Problems solved by technology
Because the heat exchange plate of the traditional vapor-liquid heat exchanger produces too much resistance under the high-speed impact of the fluid, and at the same time, it is easy to form a vortex. The vortex will reduce the fluid return velocity, the heat exchange area cannot be fully used, and the overall heat exchange performance is reduced. Therefore, , there is an urgent need for a heat exchanger that can reduce the resistance of the existing heat exchanger and improve its heat exchange capacity

The invention provides a heat exchanger. The heat exchanger comprises a plurality of annular heat exchange pipes used for containing heat exchanging fluid and a heat partition plate. The multiple annular heat exchange pipes are arranged in parallel so that a cavity can be formed in a ring. The heat partition plate is obliquely arranged in the cavity in the manner that the two opposite side edges of the heat partition plate make contact with the heat exchange pipes, and therefore the heat exchange pipes can be supported and fixed; meanwhile the cavity is divided by the heat partition plate into two spaces, and the heat exchange pipes are partitioned into evaporation pipes and cooling pipes. By means of contact of the evaporation pipes and heating bodies, fluid in the evaporation pipes is evaporated to push fluid in the cooling pipes to flow towards the evaporation pipes, and circulating heat dissipation is formed in the heat exchange pipes. According to the heat exchanger, the resistance of an existing heat exchanger can be reduced, and meanwhile the heat exchange capability of the heat exchanger is improved.
Description
【Technical field】 [0001] The invention relates to the field of heat exchangers, in particular to a heat exchanger utilizing fluid circulation conduction heat exchange. 【Background technique】 [0002] Some communication outdoor cabinets, communication cabinets, high-power power supply cabinets, server cabinets, industrial electrical cabinets and control system equipment will generate a lot of heat when they work. The heat exchanger can effectively solve the above problems by migrating outside, realizing temperature adjustment, and then meeting the heat dissipation requirements of the control cabinet in a closed state. Heat exchangers are divided into direct contact heat exchangers, partition wall heat exchangers, regenerative heat exchangers, multiple heat exchangers and fluid connection indirect heat exchangers according to the heat transfer principle. Direct contact heat exchangers are divided into two types: air heat exchangers and gas-liquid heat exchangers. Because the...
