Abstract

The utility integrated and intensified heat pipes are heat-pipe heat transmission components used with a heat exchanger. A heat-release pipe bundle and a heat-absorption pipe bundle are arranged respectively at the two ends of the transition pipe. One end of the heat-release pipe bundle and the heat-absorption pipe bundle are sealed while the other ends are welded to the two lateral ends of the transition pipe. The internal sides of the heat-release pipe bundle, the transition pipe and the heat-absorption pipe bundle are sealed to form a communicating cavity, in which is input heat transmission medium. Different heat transmission media are chosen according to different working conditions and water is used as heat transmission medium under conditions of 0 to 270 degrees Celsius. The utility model has the characteristics that dust is not easily deposited and two layers of heat-exchanging walls are formed between the cooling medium and the heating medium. The utility model has also the advantages of novel structure, reliable safety, long service life, great heat-exchanging capacity of unit area, etc. Therefore, the utility model is a novel integrated and intensified heat pipe structure of good economical efficiency and practicability.

Description

Integrated intensive heat pipe

Technical field

Integrated intensive heat pipe described in the utility model relates to the used adopting heat pipes for heat transfer element of a kind of heat exchanger.

Background technology

The pipe heat exchanger of using can be divided into tubular heat exchanger and heat-pipe heat exchanger at present.In order to increase the unit space effective heat exchange area, according to applicable cases, what have manages the external welding fin, the welding turbolator in pipe that has.Though heat exchange efficiency increases like this, owing in application, be easy to dust stratification on the fin, and dust is difficult to cleaning.Especially in the bigger heat exchange side of dustiness, can only adopt the light pipe heat-transfer surface.Therefore light pipe heat-transfer surface unit space effective heat exchange area is little, can only make huge that equipment volume does.For the liquid-liquid heat exchange, especially to the liquid heat exchange of severe corrosive, heat exchanger is easy to corrosion failure, can cause two kinds of heat exchanging liquids directly to mix, and has an accident.Though can adopt heat exchange of heat pipe, because the restriction of manufacturing process, liquid-liquid heat exchange of heat pipe unit space effective heat exchange area is little, makes equipment volume huge.At existing problem in the above-mentioned prior art, a kind of novel adopting heat pipes for heat transfer element of research and design, existing problem is very necessary in the prior art thereby overcome.

Summary of the invention

In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of integrated intensive heat pipe of research and design, makes it place two kinds to be conducted heat exchange in the middle of the medium of heat-shift.Owing to adopt integrated intensive heat pipe, the unit space effective heat exchange area is increased, dwindled volume, integrated in addition intensive heat pipe makes and forms two-layer heat exchange wall between the cold and hot heat transferring medium, and heat transferring medium is difficult for mixing.Integrated intensive heat pipe described in the utility model, its structure are that the both sides by transition conduit are welded with the heat release section tube bank respectively and endotherm section is restrained.The one end sealing of heat release section tube bank and endotherm section tube bank, the other end is welded on the end face of transition conduit.The inner communication seals cavity that forms of heat release section tube bank, transition conduit and endotherm section tube bank is equipped with heat transfer medium in the cavity.Heat release section tube bank described in the utility model also can be used the heat release section finned tube.Heat release section tube bank described in the utility model and endotherm section tube bank are provided with deflection plate.Integrated intensive heat pipe described in the utility model, heat release section heat-transfer surface and endotherm section heat-transfer surface all adopt intensive Pipe bundle structure, and two sections heat-transfer surfaces link together by transition conduit, and inside cavity is interconnected and fills heat transfer medium.Heat transfer medium is selected different media for use according to different operating modes, and generally under 0～270 ℃ of condition, heat transfer medium selects for use water to get final product.The effect that heat release section described in the utility model tube bank and endotherm section are restrained set deflection plate be to improve fluid heat transfer coefficient, improve heat-transfer effect and strengthen the intensity of restraining.The Pipe bundle structure of integrated intensive heat pipe described in the utility model is difficult for dust stratification, is applicable to the one gas heat exchange of the big gas of dust content.The heat exchanger that integrated intensive heat pipe described in the utility model is formed, make and form two-layer heat exchange wall between the cold and hot heat transferring medium, behind the heat pipe corrosion failure, heat transferring medium is difficult for mixing, and is applicable to that deep-etching, while two kinds of liquid mix there is harmfulness the back to system liquid-liquid heat exchanger.The integrated intensive inside heat pipe heat transfer medium capacity of heat transmission described in the utility model is strong, and the densification row portion by tube bank has increased the unit space effective heat exchange area on former heat transfer element architecture basics simultaneously, and exchange capability of heat strengthens.Characteristics such as the utlity model has that novel structure, security performance are reliable, long service life, unit space exchange capability of heat are big, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
