Inserts for heat exchanger tubes to be used in the heat exchanger tube inside a fuel-fired apparatus or non-fired storage tank heat exchanger. The heat exchanger insert is comprised of an inner rode as well as the cap. At least two protruding, helical guides are designed to guide heated fluid around the heat exchanger tube’s inner circumference.
Heat exchangers can be used to alter the thermodynamic properties of a particular or a few fluids. They include heat exchangers that are used in ventilation, heating and water heaters (HVAC) systems and other similar devices (generally called heat exchangers). Sometimes, HX tubes, sometimes referred to as heat exchanger tubes can be used to transfer working liquid through the HX tubes. This changes the thermal properties of both the fluid inside the HX tube and the outside fluid. The design of the device, temperatures of both the working fluid and the fluid outside can vary. Both the outside and working fluid are unable to mix. Numerous ways have been discovered to boost the efficiency (HX tube) of the device. The overall efficiency of the thermal performance of a device depends on the working fluid it is in as well as its outside fluid.
One method to improve the thermal efficiency of the HX tube is to increase the turbulence of working fluid within the HX tube by incorporating baffles or turbulators within the tube. Another approach is to ensure that the HX tube features multiple dimple likedeformations on the HX tube’s surface to increase the speed of the fluid when it deforms and thus increase the turbulent flow.
This disclosure proposes an alternate way to increase efficiency and heat exchange within a HX tube. This HX tube insert increases the time of residence for working fluids flowing through HX tubes and improves fluid contact time around the tube’s inner circumference, thereby increasing the efficiency. The HX tube insert is able to improve performance and limit the pressure drop to normal limits for combustion systems.

What is a patent?
Granted by the government to protect an invention patents grant the inventor exclusive rights to create, use to sell, and market the invention? Society gains when a innovative technology is introduced to the market. The benefits can be directly realized when people can achieve previously unattainable feats or through the opportunities for economic growth which innovation can bring (business growth, employment).
Patent protection is demanded by many pharmaceutical companies and university researchers to aid in their research and development. Patents can be granted to products, processes, or method of creating new materials. In order to be granted protection under a patent, an invention must be innovative, novel and not apparent to anyone else in the same area.
Patents reward inventors for their commercially successful inventions. They serve as a motivator for inventors to create. Patents allow inventors and small businesses to be assured that there’s a good chance they will be paid back for their time, effort and investment in technology development. This means they will be able to make a living by their work.
Businesses that have the capacity to:
Protect your innovative products and services
Increase the value, appearance, and visibility of your products on the market
Make your brand stand out from the competition.
Access to business and technical knowledge and information;
Avoid the danger of accidentally using third-party proprietary content, or losing valuable information, innovative outputs, or other creative output.
Patents transform inventors’ information into a tradeable asset, which creates new opportunities to create jobs and boost business growth through licensing or joint ventures.
Small businesses that have patent protection will be more attractive to investors in the development and commercialization of technology.
Patenting could lead to the development of new ideas and inventions. These information may be patent-worthy.
Patents can be used as an obstacle to unscrupulous third parties who profit from an invention’s efforts.
Patent-protected technology that is commercially profitable can be used to fund technological research and development (R&D), which will improve the chances for better technology in the future.
Intellectual property ownership is a way to convince lenders and investors that there are genuine chances to market your product. A single patent could provide many financing opportunities. Patents as well as other IP assets are able to be used as collateral or security for debt financing. Investors may also look at your patent assets in order to boost the value of their company. Forbes and other publications have reported that each patent could increase anywhere from $500,000 to a million dollars in company valuation.
Start-ups need a well-constructed business plan that leverages the IP to prove that your product/service is unique, superior, or innovative. Additionally, investors will be impressed if you prove that your IP rights are secure or in the process of becoming secure and that they align with your business strategy.
It is crucial to keep an invention secret prior to filing for patent protection. Public disclosure of an invention before it is filed can often destroy its novelty and make it ineligible for patent protection. Disclosures that are filed prior to filing, like for investors, test-marketing or other business partners should be done only following the signing of a confidentiality agreement.
There are many kinds of patents. Knowing them is essential to safeguard your invention. Utility patents protect new processes and machine creations. Design patents cover ornamental designs. Utility patents are the best as they protect the owner from copycats as well as other competition. In most cases they are granted for improvements or modifications to existing inventions. Utility patents also cover improvements and changes to existing inventions. A process patent would cover the acts or methods of performing a specific act. However, a chemical composition could be a combination of components.
What is the typical length of a patent? Utility patents last 20 years from the earliest date of filing, however their expirations may be extended due to delays in the patent office for instance.

Interested in finding more similar patents? Here are the steps to follow:
1. Brainstorm terms to describe your invention according to its function and composition or use.
Write down a brief detailed description of your invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Consider synonyms for the terms you chose initially. Then, take note of important technical terms as well as keywords.
Use the questions below to help you identify key words or concepts.
- What’s the goal of this invention? Is it a utilitarian device or an ornamental design?
- Is the invention a method of creating something or performing a function? Does it constitute a product?
- What is the composition of the invention? What is the physical structure of the invention?
- What’s the point of this invention?
- What are the technical terms and terms that describe an invention’s nature? To assist you in finding the correct terms, consult a technical dictionary.
2. These terms allow you to search for relevant Cooperative Patent Classifications at Classification Search Tool. To determine the most suitable classification to your invention, scan the classification’s class Schemes (class schedules). If you do not get results from the Classification Text Search, you might consider substituting your words that describe your invention using synonyms.
3. Go through the CPC Classification Definition for the CPC Classification Definition to verify the accuracy of the CPC classification that you have found. If the chosen classification includes a blue square with a “D” on its left, the hyperlink will take you to the CPC classification description. CPC classification definitions can be used to identify the specific classification’s scope, so you are sure to choose the most relevant. Additionally the definitions may include search tips and other suggestions that may be useful for further study.
4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. By focusing on abstracts and illustrations, you can narrow down your search to find the most relevant patent publications.
5. Utilize this list of most relevant patent publications to study each in depth to find similarity to your invention. Be sure to read the claims and specifications. You may find additional patents through contacting the patent examiner and the applicant.
6. Find patent applications published in the public domain using the CPC classification you picked in Step 3 from the Applications Full-Text and Image Database. You may also employ the same strategy of searching you employed in Step 4 to narrow your search results to just the most relevant patents by reading the abstracts and drawings on each page. Then, you must carefully review the published patent applications and pay particular attention to the claims as well as additional drawings.
7. You can find additional US patent publications using keywords in the AppFT and PatFT databases, and also classification searching of patents that aren’t from the United States as per below. Additionally, you can use web search engines to find non-patent patent disclosures in literature about inventions. Here are some examples:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
