[0002] When the liquid cooling unit is in use, it requires ventilation and heat dissipation in the front and back, and through-type grid holes need to be opened. Waterproof structures such as louvers cannot be used to avoid affecting the heat dissipation of the liquid cooling unit and thus the cooling effect on the battery pack. Considering that the overall waterproof requirement of the cabinet is IPX4 in design, while the waterproof requirement of the liquid cooling unit compartment is IPX0. When the liquid cooling unit is installed on the upper part of the cabinet, a sealed drainage device for the liquid cooling unit compartment needs to be designed to prevent rainwater from leaking to the electrical compartment below the liquid cooling unit during outdoor cooling, causing a short-circuit risk, and at the same time ensuring that the rainwater can be discharged outside the cabinet. Therefore, there is a particular need for a sealed drainage device for a liquid cooling unit compartment of an energy storage liquid cooling integrated cabinet.
[0003] However, in the existing design of liquid cooling units, while ensuring the efficient heat dissipation of the liquid cooling unit, it is also necessary to take into account the overall waterproof requirement of the cabinet and the special waterproof requirement of the liquid cooling unit compartment. In traditional designs, directly opening through-type grid holes can effectively improve the heat dissipation performance, but the risk of rainwater penetration increases significantly, resulting in the problem of sealed drainage of the liquid cooling unit.

A first drainage hole 10 is opened on the lower surface of the cabinet front door 6. A liquid cooling unit installation tray 11 is fixedly installed on one surface of the cabinet frame 2. A cabinet waterproof eaves 12 is fixedly installed on one surface of the cabinet frame 2. A second drainage hole 13 is opened on one surface of the cabinet waterproof eaves 12. Through the settings of the cabinet body 1, the cabinet frame 2, the baffle 3, the liquid cooling unit 4, the connecting piece 5, the cabinet front door 6, the front air inlet grid hole 7, the cabinet rear door 8, the rear air outlet grid hole 9, the first drainage hole 10, the liquid cooling unit installation tray 11, the cabinet waterproof eaves 12 and the second drainage hole 13, a waterproof sealing rubber strip is installed in a whole circle on the cabinet waterproof eaves 12 of the cabinet front door 6 and the cabinet rear door 8, and then the cabinet front door 6 and the cabinet rear door 8 are closed through the connecting piece 5. When the cabinet door is in the closed state, the cabinet door compresses the waterproof rubber strip to play a waterproof sealing role. Then, the liquid cooling unit installation tray 11 is fully welded to the cabinet body and a sealing glue is applied in a whole circle after welding for sealing. By combining these two methods, a waterproof and sealed isolation effect is achieved between the liquid cooling unit 4 compartment and other compartments of the cabinet. The air inlet and outlet before and after the liquid cooling unit 4 compartment are ventilated through the front air inlet grid hole 7 and the rear air outlet grid hole 9 opened on the cabinet front door 6 and the cabinet rear door 8. When it rains during outdoor work, rainwater will enter the liquid cooling unit 4 compartment. Due to the sealing reason, the rainwater will not leak to the lower part and other adjacent compartments. The second drainage hole 13 is opened on the cabinet waterproof eaves 12 for drainage. After the water is discharged, it drains along the gap between the cabinet door and the cabinet waterproof eaves 12 to the bottom of the cabinet door. The first drainage hole 10 is opened at the bottom of the cabinet door to drain the water out of the cabinet.
[0020] Further, the baffle plates 3 are installed at equal intervals on one surface of the cabinet frame 2, and the outer surface dimensions of the baffle plates 3 match the inner surface dimensions of the cabinet frame 2. Through the setting of the baffle plates 3, the outer shell of the tank body 1 is protected.
[0021] Further, the outer surface dimensions of the liquid cooling unit 4 match the inner surface dimensions of the cabinet frame 2. The connecting members 5 are installed at equal intervals on one surface of the tank body 1. Through the setting of the connecting members 5, the cabinet front door 6 and the cabinet rear door 8 are opened and closed.
[0022] Further, the cabinet rear door 8 has the same dimensions as the cabinet front door 6. The cabinet front door 6 is connected to the tank body 1 through the connecting member 5. Through the setting of the cabinet front door 6, the equipment inside the tank body 1 is protected.
[0023] Further, the front air inlet grid holes 7 are opened at equal intervals on one surface of the cabinet front door 6, and the rear air outlet grid holes 9 are opened at equal intervals on one surface of the cabinet rear door 8. Through the setting of the front air inlet grid holes 7, ventilation operation can be carried out on the tank body 1.
[0024] Further, the outer surface dimensions of the liquid cooling unit installation tray 11 match the inner surface dimensions of the cabinet frame 2. The cabinet waterproof eaves 12 are symmetrically installed with respect to the central axis of the liquid cooling unit installation tray 11. Through the setting of the cabinet waterproof eaves 12, water is prevented from entering the interior of the tank body 1.
[0025] Further, the second drain holes 13 are opened at equal intervals on one surface of the cabinet waterproof eaves 12, and a waterproof sealant strip is installed around the cabinet waterproof eaves 12. Through the setting of the second drain holes 13, the accumulated water can be discharged.
[0026] Working principle: First, install a waterproof sealing strip around the cabinet body waterproof eaves 12 on the front door 6 and the rear door 8 of the cabinet. Then, close the front door 6 and the rear door 8 of the cabinet through the connecting piece 5. When the cabinet door is in the closed state, the cabinet door compresses the waterproof strip to play a waterproof and sealing role. Then, the liquid cooling unit installation tray 11 is fully welded to the cabinet body and sealed with sealant around the weld. By combining these two methods, a waterproof and sealing isolation effect is achieved between the chamber of the liquid cooling unit 4 and other chambers of the cabinet. The air intake and exhaust before and after the chamber of the liquid cooling unit 4 are ventilated through the front air intake grid holes 7 and the rear air exhaust grid holes 9 opened on the front door 6 and the rear door 8 of the cabinet. When encountering rainy weather during outdoor work, rainwater will enter the chamber of the liquid cooling unit 4. Due to the sealing, the rainwater will not leak to the lower part and other adjacent chambers. Drainage is carried out by opening a second drain hole 13 on the cabinet body waterproof eaves 12. After the water is discharged, it drains along the gap between the cabinet door and the cabinet body waterproof eaves 12 to the bottom of the cabinet door. The bottom of the cabinet door is provided with a first drain hole 10 to drain the water out of the cabinet.
