Inorganic superconducting heat pipe technology is a new type of heat transfer material technology independently developed by Huaqu Group with independent intellectual property rights. After nearly 20 years of development, this technology has continuously innovated and improved in mechanism and application research, and has obtained recognition from the United States, the European Community, and other countriesPatent authorizations for inventions in 27 countries and regions. At the same time, through the 14 year long systematic demonstration of Stanford Research Institute in the United States and the application assessment of more than 10 well-known scientific research institutions at home and abroad, such as GE, the University of Alabama, Switzerland SGS, the Chinese Academy of Sciences, it is proved that its technical performance is at the international leading level. In 2012, this technology won the German Bavarian Chemistry Award.

Application scope of inorganic superconducting heat pipe technology

The inorganic superconducting heat pipe engineering heat exchanger includes a series of products such as air preheater, water preheater, steam generator, dual preheater, etc., which are mainly suitable for petroleum exploration and petrochemicalsAll industries related to thermal energy utilization, including the refining industry, metallurgy, chemical industry, building materials, ground temperature melting, frozen soil prevention, etc., focus on the use of various heating devices and the comprehensive utilization of waste heat.

Main features of the product

Wide applicabilityCan be applied to heat transfer between various media such as gas gas, gas vapor, gas-liquid, liquid-liquid, etc.

High heat transfer coefficientTaking gas gas exchange as an example, its equivalent heat transfer coefficient "K" can be increased by 5-10 times compared to traditional tube heat exchange.

Low fluid resistanceBoth types of exchange media go outside the tube, without the need for back and forth, greatly shortening the process, and the flow direction of the media is consistent with the direction of the heat sink, thereby reducing flow resistance.

Compact equipment structureInorganic superconducting heat pipes made of finned tubes have compact structure, small equipment volume, and light weight when used in combination with heat exchange equipment, making them suitable for limited installation space.

During the operation of the equipment, it is not easy to form dust and scale, and it is not easy to block. In the design of the equipment, the medium flow rate can be adjusted to have the ability to self clean dust, and the installation and layout of inorganic superconducting heat pipes can also be adjusted to achieve the purpose of self cleaning and easy cleaning after scaling.

According to the working environment of the equipment, the surface temperature distribution of inorganic superconducting heat pipes can be changed by adjusting the heat transfer area between the cold and hot media to avoid low-temperature acid dew point corrosion.

Has good replaceabilityThe heat transfer elements work independently of each other and can be connected to the equipment through flanges (especially gas air exchange), suitable for separate disassembly and replacement.

Heat transfer components may fail due to special working conditions such as wear, erosion, corrosion, etc. The cold and hot media will not mix, and there is no need to stop the equipment for emergency repairs. This feature is particularly suitable for gas-Gas exchange or heat exchange between two liquids in a non miscible working environment.

During normal use, inorganic superconducting heat pipes have no transmission components and do not require maintenance.
