Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupled phase change cooling technology, and in particular to a vacuum high-efficiency optimization device for direct cooling units with coupled phase change cooling. Background Technology
[0002] A direct-cooling unit is a device that achieves cooling and refrigeration through the circulation of refrigerant. Its working principle mainly includes the following steps: the refrigerant absorbs heat in the evaporator, cooling the surrounding air or object, then is compressed into a high-temperature, high-pressure gas by the compressor, enters the condenser to dissipate heat and become liquid, and finally returns to the evaporator to continue the cycle.
[0003] The existing technology includes a housing, battery cell modules, an arch-shaped liquid cooling structure, PCM filling material, and a housing cover. When the energy storage system is working, the air conditioning unit starts normally, and the PCM filling material is in a solid state, participating in the system operation as an intermediate heat transfer medium. When the air conditioning unit stops abnormally, it cannot effectively transfer heat to the outside of the housing. At this time, the PCM filling material continues to absorb heat from the battery cells, and it undergoes a phase change from solid to liquid, but the temperature does not change significantly, which can avoid the risk of excessive temperature rise caused by the system's inability to dissipate heat in the short term.
[0004] The existing technology also has the following drawbacks: When using coupled phase change cooling for direct cooling units, traditional flange seals rely on bolt tightening. Thermal expansion and contraction can easily lead to micro-leakage on the sealing surface, requiring frequent start-stop of the vacuum pump to replenish gas, resulting in excessive energy consumption. If vacuum sealing is not possible, the overall cooling efficiency and cooling loss cannot meet the current requirements. Utility Model Content
