Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of resistance, specifically to a simple water -cooled resistance. BACKGROUND

[0002] With the development of power electronics, the use of load is more and more, especially liquid cooling load, has great performance advantage, use is more and more widely, liquid cooling load is also towards small volume direction development, power is more and more big, volume is more and more small. The applicant created the technology with the publication number CN209609063U and the name of a phase change cooling type load box before, the resistance unit is immersed in the phase change liquid medium, in the use process, the phase change liquid medium absorbs the heat of the resistance unit and converts into gaseous medium, the gaseous medium flows to the condenser cooling liquefaction, and then backflows to the container, the phase change liquid medium automatically circulates from the liquid-gas-liquid process, without using the traditional water pump, so the energy consumption is low, the resistance unit is directly immersed in the phase change liquid medium, absorbs heat quickly, and can meet the high heat dissipation demand.

[0003] From the above, the insulation liquid of the existing immersion type water-cooled resistance relies on evaporation and condensation to realize circulation, and the evaporated insulation liquid will leave the container and enter the condenser, therefore, when the resistance unit generates a lot of heat, a large amount of insulation liquid will evaporate, and if the evaporation cannot be condensed back in time, the liquid insulation liquid in the container may be too little, which may cause the risk of overheating of the resistance unit without insulation liquid immersion in a local part.

[0004] Then the applicant developed a compact liquid-cooled resistance disclosed in the Chinese patent document with the publication number CN116031032A, which comprises a sealed container and a resistance unit accommodated in the container. The internal space of the container is divided into a heat exchange zone and a condensation zone. The condensation zone is located above the heat exchange zone. The heat exchange zone is loaded with insulation liquid. The resistance unit is immersed in the heat exchange zone. The resistance unit comprises a plurality of resistance sheets arranged side by side. The plurality of resistance sheets are connected in parallel or in series with each other. The container further comprises a heat conduction mechanism. The heat conduction mechanism comprises a lower heat conduction pipe laid on the surface of the plurality of resistance sheets and an upper heat conduction pipe arranged in the condensation zone. The upper heat conduction pipe and the lower heat conduction pipe are sealed and pass out of the container and are connected to a water supply mechanism to circulate cooling liquid therein. The resistance sheet directly contacts the insulation liquid, has good heat dissipation performance, and the internal insulation liquid only has heat conduction effect and does not participate in external circulation. The amount of insulation liquid used is small, the pollution is small, the stability of cooling use is improved, the use of expensive insulation liquid is reduced, and the cost is reduced.

[0005] The above-mentioned prior art uses insulation liquid as cooling liquid, which can directly contact the resistance and take away heat. However, the above-mentioned resistance has a large volume and is not suitable for some small volume occasions. SUMMARY
