Technical Field

[0002] The liquid cooling integrated machine equipment in the prior art all uses ordinary battery trays. The trays are hollowed out with large round holes to cooperate with the liquid cooling integrated machine for heat dissipation. When the equipment starts the charging and discharging process, the liquid cooling integrated machine equipment detects the temperature of the storage location, and adjusts the speed of the cold air blower next to the liquid cooling heat exchanger according to the changes in the temperature inside the storage location to control the heat generation inside the storage location. This adjustment method requires the design of a large-area heat exchanger on the equipment, which occupies a large space. The manufactured equipment occupies a large area and has a high cost. The heat exchanger is far away from the heat source battery and power module in physical space, and the cooling and heat dissipation effect is poor. The temperature uniformity in the storage location is difficult to control, and the temperature change inside the storage location cannot be effectively controlled, resulting in a sluggish reaction of the temperature control in the storage location. In addition, the liquid cooling integrated machine equipment in the prior art only adjusts the air volume, but does not adjust the flow rate of the coolant.
