When the cooling liquid circulates in the connecting pipe 300, the cooling liquid circulates through the battery, and then the heat of the battery is taken away by the cooling liquid. Then, the liquid cooling host 200 radiates heat to the coolant, so that the coolant has a good heat dissipation effect in the next cycle. The cooling liquid can make the battery heat dissipation uniform and sufficient, and ensure the safety of the battery. The liquid-cooled temperature control cabinet 10 provided in this embodiment can effectively improve the battery temperature control problem of the energy storage battery cabinet, ensure uniform battery temperature, prolong the service life of the battery, and avoid potential safety hazards caused by uneven temperature or overheating of the battery.

Further, it should be noted that when the battery is dissipated through the cooling host and the connecting pipe 300, heat can be transferred in at least two ways: directly through the coolant and indirectly through the coolant. When heat is transferred directly through the cooling liquid, the battery is immersed in the cooling liquid, and the cooling liquid is an insulating cooling liquid; when the heat is transferred indirectly through the cooling liquid, the cooling liquid can be flowed in the connecting pipe 300.
