Description

Technical Field

[0001] The present invention belongs to the technical field of cooling high-voltage electrical systems of energy storage batteries, and more specifically, particularly relates to a liquid cooling device for high-voltage electrical systems of energy storage batteries with a capacity of more than 800AH. Background Art

[0002] Above 800AH means that the rated capacity of the energy storage battery is above 800AH. The high-voltage electrical system of the energy storage battery generates a lot of heat and has limited heat dissipation space. It is difficult to achieve temperature control under natural ventilation conditions, which can easily affect the life of the energy storage battery and is not conducive to the safe use of the energy storage battery. In order to improve the heat dissipation effect of the high-voltage electrical system of the energy storage battery, liquid cooling is usually used to reduce the temperature.

[0003] The liquid cooling devices currently in use have the following problems: 1. The refluxed coolant usually comes into direct contact with the coolant in the water tank without mixing, resulting in an unstable coolant temperature at the cooling pipe, affecting the liquid cooling effect; 2. When the coolant circulates, it cannot assist in dissipating heat in the radiator, affecting the heat dissipation effect of the coolant; 3. The water tank is generally installed and fixed with screws. After the water tank is installed, the screws cannot be automatically tightened and limited, resulting in the screws being easily loosened during subsequent use. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, when the servo motor rotates forward, the hollow insulation block moves downward under the action of the control rod, which squeezes the coolant under the hollow insulation block, so that the coolant in the stainless steel box is discharged through the cooling pipe joint, and the high-voltage electrical system of the energy storage battery is automatically liquid-cooled. The coolant after liquid cooling of the high-voltage electrical system of the energy storage battery enters the radiator, and the coolant after heat dissipation by the radiator flows back to the stainless steel box through the return pipe joint. The returned coolant is located above the hollow insulation block. The setting of the hollow insulation block blocks the returned coolant, avoiding the returned coolant from directly contacting the coolant under the hollow insulation block, ensuring that the temperature of the coolant under the hollow insulation block is in a stable state, and improving the liquid cooling effect of the high-voltage electrical system of the energy storage battery;

[0020] In addition, when the servo motor reverses, the hollow insulation block moves upward under the action of the control rod, which squeezes the coolant above the hollow insulation block. At this time, the two return springs are compressed, causing a gap between the two sealing discs and the hollow insulation block. The coolant above the hollow insulation block flows to the bottom of the hollow insulation block through the gap between the two sealing discs and the hollow insulation block. When the coolant above passes through the hollow insulation block, the two cross mounting frames and the gap between the two sealing discs and the hollow insulation block can automatically mix the coolant above, ensuring that the coolant temperature below the hollow insulation block is basically in a stable state. When the hollow insulation block stops moving, the two sealing discs are automatically reset under the action of the two return springs.

[0021] 2. In the present invention, when the servo motor rotates forward or reversely, the two linkage push rods move back and forth left and right under the action of the two arc-shaped linkage rods and the two return springs;

[0022] In addition, when the two linked push rods move outward at the same time, the two auxiliary push plates squeeze the air in the two auxiliary shells, so that the air in the two auxiliary shells is discharged through two rows of exhaust pipes, which has an auxiliary heat dissipation effect on the radiator. When the two linked push rods move inward at the same time, the pressure in the two auxiliary shells becomes smaller, allowing external air to enter the auxiliary shells through the two intake pipes.

[0023] 3. In the present invention, after the installation of the second mounting frame is completed, the staff can pull the two positioning pins forward. At this time, the stainless steel box automatically moves downward under the action of gravity. After the stainless steel box moves downward, the two positioning pins are inserted into the two circular limit grooves above, and the four mounting circular holes are automatically separated from the four mounting screws. The two limit blocking frames automatically press and limit the four mounting screws, thereby avoiding the four mounting screws from loosening, making the second mounting frame more secure after installation.

When the coolant above passes through the hollow insulation block 201, the gap between the two cross mounting frames 202 and the two sealing discs 204 and the hollow insulation block 201 can automatically mix the coolant above, ensuring that the coolant temperature below the hollow insulation block 201 is basically in a stable state.

After the four installation screws 502 are tightened, the staff pulls the two positioning pins 504 forward to make the stainless steel box 101 automatically move downward under the action of gravity, and then loosens the two positioning pins 504 to insert the two positioning pins 504 into the two circular limiting grooves 1011 above. The four installation circular holes 6021 are automatically separated from the four installation screws 502, and the two limiting blocking frames 602 automatically press and limit the four installation screws 502, thereby preventing the four installation screws 502 from loosening, making the installation frame 2 501 more secure after installation; one end of the external cooling pipe is connected to the cooling pipe joint 103 is connected, and then the external cooling pipe is set in the high-voltage electrical system of the energy storage battery, and then the other end of the external cooling pipe is connected to the external radiator, and then the return pipe joint 102 is connected to the radiator through the external return pipe; when the high-voltage electrical system of the energy storage battery needs to be liquid-cooled, the staff starts the servo motor 302. When the servo motor 302 rotates forward, the hollow insulation block 201 moves downward under the action of the control rod 303, and squeezes the coolant under the hollow insulation block 201, so that the coolant in the stainless steel box 101 is discharged through the cooling pipe joint 103, which automatically cools the high-voltage electrical system of the energy storage battery.

At this time, the two return springs 206 are compressed, causing a gap between the two sealing discs 204 and the hollow insulation block 201. , the coolant above the hollow heat-insulating block 201 flows to the bottom of the hollow heat-insulating block 201 through the gap between the two sealing discs 204 and the hollow heat-insulating block 201. When the coolant above passes through the hollow heat-insulating block 201, the gap between the two cross mounting frames 202 and the two sealing discs 204 and the hollow heat-insulating block 201 can automatically mix the coolant above, ensuring that the coolant temperature below the hollow heat-insulating block 201 is basically in a stable state. When the hollow heat-insulating block 201 stops moving, the two sealing discs 204 automatically reset under the action of the two reset springs 1 206; when the servo motor 302 rotates forward or reversely, the two linkage push rods 403 move back and forth left and right under the action of the two arc-shaped linkage rods 305 and the two reset springs 2 404;When the two linkage push rods 403 move outward at the same time, the two auxiliary push plates 402 squeeze the air in the two auxiliary shells 401, so that the air in the two auxiliary shells 401 is discharged through the two rows of exhaust pipes 406, which has an auxiliary heat dissipation effect on the radiator. When the two linkage push rods 403 move inward at the same time, the pressure in the two auxiliary shells 401 decreases, so that the external air enters the auxiliary shell 401 through the two intake pipes 405. ;
