[0030] Working principle:

The coolant in the liquid cooling chamber is circulated on the hot side of the heat exchange device 2 by the circulation pump 8, and the liquid in the heat sink 3 is circulated on the cold side of the heat exchange device 2. The liquid in the heat sink 3 enters the heat exchange device 2 to exchange heat with the heat-generating coolant. The liquid at the end of the heat exchange device 2 connected to the heat sink 3 absorbs heat and expands and vaporizes, thereby achieving the cooling of the coolant. The vaporized specific liquid in the heat sink 3 is compressed into liquid by the compressor 4, and then flows into the condensation system 5. The fan 6 dissipates the heat for the condensation system 5. The liquid after the heat is cooled is increased in flow rate by the throttling device 7 and then flows back to the heat exchange device 2. This cycle is repeated to achieve continuous and stable heat dissipation of the heat source to be cooled.
