Description
Technical Field
[0001] The utility model relates to the technical field of cooling equipment, in particular to a liquid cooling plate for PCS. Background Art
[0002] PCS is short for energy storage converter. The energy storage converter can control the charging and discharging process of the battery and perform AC / DC conversion. It can directly supply power to AC loads in the absence of a power grid. PCS is composed of a DC / AC bidirectional converter, a control unit, etc. The PCS controller receives background control instructions through communication and controls the converter to charge or discharge the battery according to the sign and size of the power instruction, thereby realizing the regulation of the active power and reactive power of the power grid. The PCS controller communicates with the BMS through the CAN interface to obtain battery pack status information, which can realize protective charging and discharging of the battery and ensure safe battery operation.

[0021] The side of the liquid cooling plate 9 close to the Peltier 4 is connected to the side of the aluminum fin 11 facing away from the cover plate 16 . The aluminum fin 11 and the aluminum plate 15 can dissipate part of the heat inside the liquid cooling plate 9 .
[0022] The interior of the transfer cavity 14 is hollow, and the transfer cavity 14 and the air pipe 13 are interconnected, so that air can be blown into the interior of the aluminum plate 15 .

At the same time, the fan 12 can be turned on to absorb the outside air into the interior of the transfer cavity 14 through the air pipe 13. The transfer cavity 14 is aligned with the aluminum plate 15, so that the air can quickly pass through the gap inside the aluminum plate 15.

At the same time, when the gas passes through the inside of the aluminum plate 15, the aluminum plate 15 can be dissipated. Subsequently, when the Peltier 4 is turned on, the first storage cavity 3 and the second storage cavity 7 can be cooled, so that the water inside the first storage cavity 3 and the second storage cavity 7 can be cooled again to avoid the water temperature being too high, and the work is completed.
