DETAILED DESCRIPTION

[0038] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0039] like Figures 1 to 17 The integrated liquid-cooled energy storage cabinet shown comprises a support base 1, the top of the support base 1 is fixedly connected to an energy storage cabinet body 2, one side of the energy storage cabinet body 2 is hingedly connected to a cabinet door 4 through a hinge 3, and the interior of the energy storage cabinet body 2 is provided with a fixed baffle 5, a first movable baffle 6 and a second movable baffle 7, the fixed baffle 5 is located on the bottom surface of the interior of the energy storage cabinet body 2, the first movable baffle 6 is located between the fixed baffle 5 and the second movable baffle 7 and contacts each other, and the first movable baffle 6 and the second movable baffle 7 are connected to a vertical movable mechanism;

[0040] A liquid storage tank 8 is fixedly connected to the inside of the energy storage cabinet 2. The liquid storage tank 8 is located between the fixed baffle 5 and one side of the energy storage cabinet 2. A matching liquid injection mechanism is connected to the liquid storage tank 8. A plurality of mounting racks 9 are fixedly connected to the inside of the energy storage cabinet 2. The mounting racks 9 are all located above the liquid storage tank 8. A plurality of battery assemblies 10 are fixedly installed on the top of the mounting racks 9. A condenser 11 is arranged above the inside of the energy storage cabinet 2. A circulating condensing mechanism is connected to the condenser 11. When working, the prior art usually sprays the energy storage equipment to cool it down and circulates the coolant to cool it. When the coolant is sprayed on the energy storage equipment, it is difficult for the coolant to come into synchronous contact with the surface of the energy storage equipment, and multiple groups of energy storage equipment need to be installed in the energy storage cabinet. The range and sequence of contact between the coolant and the multiple groups of power storage devices will affect the degree of cooling of the power storage devices, thereby causing a large temperature difference between the multiple groups of power storage devices, affecting the cooling effect of the energy storage cabinet and the stability of the internal temperature; the technical solution can solve the above problems, and the specific working method is as follows: the first movable baffle 6 and the second movable baffle 7 are vertically raised by the action of the vertical movable mechanism, and the first movable baffle 6 and the fixed baffle 5 and the second movable baffle 7 are sealed and shielded by mutual contact. During the rising process of the first movable baffle 6 and the second movable baffle 7, the liquid storage tank 8 outputs the internal insulating coolant to the outside by cooperating with the injection mechanism, and is located between the fixed baffle 5, the first movable baffle 6 and the second movable baffle 7 and the energy storage cabinet The battery assembly 10 and the condenser 11 on the mounting frame 9 are immersed in the insulating coolant in the sealed space formed by the body 2. When the battery assembly 10 releases heat during operation, the heat is absorbed by the immersion contact between the coolant and the battery assembly 10. Under the action of the circulating condensation mechanism, the condenser 11 continuously absorbs heat and condenses. The condenser 11 continuously absorbs and conducts the heat in the coolant and discharges it from the energy storage cabinet, thereby completing the cooling of the battery assembly 10. The battery assembly 10 is immersed in the coolant, so that the coolant and the surface of the battery assembly 10 are in synchronous contact. Multiple battery assemblies 10 are immersed in the coolant. Under the action of the circulating condensation mechanism, the condenser 11 cools the coolant. The coolant is used to cool the battery assembly 10. The conduction and diffusion of heat reduces the temperature difference between multiple battery assemblies 10 and the temperature difference between the battery assemblies 10 and the coolant, thereby improving the cooling effect of the battery assembly 10 and the stability of the temperature inside the energy storage cabinet 2. When the battery assembly 10 is inspected and maintained, the cabinet door 4 is opened, and the first movable baffle 6 and the second movable baffle 7 are moved downward and located on one side of the liquid storage tank 8 under the action of the vertical movable mechanism, thereby reducing the obstruction of the battery assembly 10. In the process of the first movable baffle 6 and the second movable baffle 7 moving downward, the coolant that submerges the battery assembly 10 is returned to the inside of the liquid storage tank 8 by cooperating with the injection mechanism, thereby preventing the coolant from overflowing when the shielding and sealing effect is lost, and improving the convenience of inspecting the battery assembly 10.

Two circular through holes 23 are provided on the top of the liquid storage tank 8, and an L-shaped tube 24 is fixedly connected to the bottom of the liquid storage tank 8. One end of the L-shaped tube 24 passes through the support base 1 and extends to the outside of the support base 1; the second movable baffle 7 moves upward, driving the two circular rods 22 to move upward along the inside of the limiting ring 21, and when the second movable baffle 7 drives the first movable baffle 6 to move upward, the circular rod 22 drives the limiting ring 21 to move upward through the action of the limiting mechanism, so that the piston plate 20 moves upward along the inside of the liquid storage tank 8 and the liquid storage tank 8 is filled with liquid. The insulating coolant in the part is squeezed and transported outward along the circular through hole 23, so that the coolant immerses multiple battery assemblies 10, and when the piston plate 20 moves upward along the inside of the liquid storage tank 8, the fixed connection between the L-shaped tube 24 and the bottom of the liquid storage tank 8 allows the position where negative pressure is generated below the piston plate 20 to be supplemented with intake air. When the second movable baffle 7 moves downward, the limiting ring 21 drives the piston plate 20 to move downward through the action of the limiting mechanism, and the L-shaped tube 24 exhausts air outward synchronously, and when the first movable baffle 6 moves downward, the circular rod 22 moves downward along the inside of the limiting ring 21. Through the above-mentioned sequence of movement, the coolant inside the liquid storage tank 8 is synchronized with the vertical rise of the first movable baffle 6 during the outward transportation process, and is preferentially synchronized with the vertical descent of the second movable baffle 7 during the inward reflux process, so as to prevent the coolant from losing its sealing barrier and causing overflow.

The heat of the coolant is driven by the contact conduction between the condenser 11 and the coolant, and the condenser 39 is used to dissipate the heat and cool down the cooling water in the water tank 37, and then the heat generated on the condenser 39 is quickly discharged by the cooling fan 40, so as to circulate and cool down the coolant.

[0046] As a further implementation scheme of the present invention, the portion of the condenser 11 located at the energy storage cabinet 2 is reciprocatingly bent; during operation, the reciprocating bending of the condenser 11 increases the contact area between the condenser 11 and the coolant, thereby improving the contact heat conduction effect of the condenser 11.

[0047] Working principle of the present invention:

[0048] The first movable baffle 6 and the second movable baffle 7 are vertically raised by the action of the vertical movable mechanism, and the first movable baffle 6 is sealed and shielded by the mutual contact between the fixed baffle 5 and the second movable baffle 7. During the rising process of the first movable baffle 6 and the second movable baffle 7, the liquid storage tank 8 outputs the internal insulating coolant to the outside by cooperating with the action of the liquid injection mechanism, and is located in the sealed space formed by the fixed baffle 5, the first movable baffle 6, the second movable baffle 7 and the energy storage cabinet 2, so that the battery assembly 10 and the condenser 11 on the mounting frame 9 are immersed in the insulating coolant. When the battery assembly 10 releases heat during operation, the heat is absorbed by the immersed contact between the coolant and the battery assembly 10, and the condenser 11 continuously absorbs heat and condenses under the action of the circulating condensation mechanism, so that the condenser 11 continuously absorbs and conducts the heat in the coolant and discharges it from the energy storage cabinet, thereby completing the cooling of the battery assembly 10. The battery assembly 10 is immersed in the coolant. The cooling liquid and the surface of the battery assembly 10 are brought into synchronous contact, and a plurality of battery assemblies 10 are immersed in the cooling liquid. Under the action of the circulating condensation mechanism, the condenser 11 cools the cooling liquid. The temperature difference between the plurality of battery assemblies 10 and the temperature difference between the cooling liquid and the cooling liquid are reduced by utilizing the heat conduction and diffusion effect of the cooling liquid, thereby improving the cooling effect of the battery assembly 10 and the stability of the temperature inside the energy storage cabinet 2. When the battery assembly 10 is inspected and maintained, the cabinet door 4 is opened, and the first movable baffle 6 and the second movable baffle 7 are moved downward and located on one side of the liquid storage tank 8 under the action of the vertical movable mechanism, thereby reducing the obstruction of the battery assembly 10. In the process of the first movable baffle 6 and the second movable baffle 7 moving downward, the cooling liquid that submerges the battery assembly 10 is returned to the liquid storage tank 8 by cooperating with the action of the liquid injection mechanism, thereby preventing the cooling liquid from overflowing when the shielding and sealing effect is lost, and improving the convenience of inspecting the battery assembly 10.
