[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] In the related art, in order to meet the refrigeration needs of the energy storage container, the layout design of the refrigeration mechanism generally chooses to arrange multiple refrigeration equipment according to the refrigeration needs to meet the working needs of the energy storage container. The surface of the current refrigeration equipment is generally arranged with multiple air inlets and air outlets. Commonly, an air inlet and an air outlet are arranged on the front of the refrigeration equipment, and an air inlet is arranged on each side. In the working state, there will be a mixed flow of inlet and outlet air, resulting in a decrease in the heat dissipation efficiency of the refrigeration equipment. Based on this, the utility model provides a refrigeration mechanism and an energy storage device for an energy storage device, so as to solve such technical problems.

[0030] The following will refer to Figure 1 A refrigeration mechanism for an energy storage device and an implementation process of the energy storage device provided by the utility model are described in detail.

[0031] Reference Figure 1 This embodiment discloses a refrigeration mechanism for an energy storage device, comprising:

[0032] A plurality of refrigeration devices 5, wherein the refrigeration device 5 comprises a first side surface and a pair of second side surfaces adjacent to the first side surface, the pair of second side surfaces are symmetrical, a first air inlet and an air outlet are provided on the first side surface, and a second air inlet is provided on the pair of second side surfaces respectively, and a second air inlet of each refrigeration device 5 faces the second air inlet of the refrigeration device 5 adjacent thereto;

[0033] The supporting device includes a base, a top plate, a plurality of first supporting mechanisms disposed between the base and the top plate, and a pair of second supporting mechanisms disposed between the base and the top plate, a plurality of refrigeration devices 5 are disposed on the base, a plurality of first supporting mechanisms are located between the pair of second supporting mechanisms, and a plurality of refrigeration devices 5 are respectively located between adjacent first supporting mechanisms and second supporting mechanisms and between a plurality of first supporting mechanisms;

[0034] A plurality of stoppers 1, the first support mechanism and the refrigeration device 5 as well as the second support mechanism and the refrigeration device 5 are connected via the stoppers 1, and the stoppers 1 are located between the air outlet and the second air inlet;

[0035] The air guiding channel 3 has one end connected to the first air inlet and the other end bent toward a side away from the air outlet.

[0036] When in use, a stopper 1 is arranged between the second air inlet of the refrigeration device 5 and the air outlet of the refrigeration device 5, and an air guide channel 3 is arranged at the first air inlet of the refrigeration device 5. The stopper 1 and the air guide channel 3 reduce the influence of mixed flow of inlet and outlet air, improve the refrigeration efficiency, ensure the heat dissipation of the refrigeration device 5, and control the heat dissipation cost of the refrigeration device 5.

[0037] As an optional implementation, the first supporting mechanism includes a pair of supporting members 8 , and a ventilating opening connected to the second air inlet is formed between the pair of supporting members 8 .

[0038] A pair of support members 8 cooperate with the stopper 1 to form a vent connected to the second air inlet, which is effectively separated from the air outlet of the refrigeration device 5 .

[0039] As an optional embodiment, an air intake grille 6 is provided in the vent.

[0040] The air inlet grille 6 fixed at the vent can effectively filter the air entering the second air inlet.

[0041] As an optional implementation, the angle at which the air guiding channel 3 is bent toward the side away from the air outlet is 90°.

[0042] An air guide channel 3 is fixed on the first air inlet of the refrigeration device 5, and the air outlet end of the air guide channel 3 is connected to the first air inlet of the refrigeration device 5. The air guide channel 3 is a 90° bent structure, and the air inlet end of the air guide channel 3 is arranged toward the ground, so that the first air inlet of the refrigeration device 5 keeps sucking air from below. Since the hot air discharged from the air outlet of the refrigeration device 5 will move upward, the setting of the air guide channel 3 can significantly prevent hot air from entering the first air inlet.

[0043] As an optional implementation, one end of the stopper 1 is connected to the top plate, and the other end is connected to the base.

[0044] As an optional implementation, the second supporting mechanism is a column structure 7 .

[0045] The vertically arranged stopper 1 fixed by the column structure 7 fixed to the refrigeration equipment 5 and the energy storage container 4 prevents the hot gas discharged from the air outlet of the refrigeration equipment 5 from returning to the refrigeration equipment 5 through the second air inlet on the side of the refrigeration equipment 5, and plays a fixing role on the side of the refrigeration equipment 5.

[0046] As an optional implementation, the refrigeration device 5 includes a water-cooling coil, which extends into the energy storage container 4 of the energy storage device. The water-cooling coil is used to perform heat exchange with the energy storage container 4.

[0047] As an optional implementation, the refrigeration equipment 5 in this embodiment can be selected as a water cooler or an air cooler, and the number of units can be set according to the required cooling capacity.

[0048] There are two refrigeration devices 5, and the refrigeration devices 5 are water-cooled machines.

[0049] By simultaneously providing a stopper 1 at the second air inlet on the left and right sides of the refrigeration device 5 and providing an air guide channel 3 at the first air inlet at the lower front part of the refrigeration device 5, heat cannot flow back into the refrigeration device 5. By analyzing the paths of inlet and outlet air through simulation means, the ventilation and heat dissipation effects are well optimized while ensuring the structural strength.

[0050] On the other hand, the utility model also provides an energy storage device, comprising:

[0051] The energy storage container 4; and the above-mentioned refrigeration mechanism for the energy storage device, the refrigeration mechanism is used to perform heat exchange with the energy storage container 4. Specifically, the refrigeration equipment 5 can be arranged on the outside of the energy storage container 4, and the cooling component of the refrigeration equipment 5 extends into the interior of the energy storage container 4, or the refrigeration equipment 5 and its cooling component are directly arranged on the inside of the energy storage container 4. The cooling component of the refrigeration equipment 5 can be a water-cooled coil or an air duct, which can perform cooling operations on the interior of the energy storage container 4.

[0052] As an optional embodiment, the energy storage container 4 includes a box body and an energy storage battery pack arranged in the box body, and the refrigeration device 5 is used to perform heat exchange with the energy storage battery pack. Specifically, the refrigeration device 5 can be arranged on the outside or inside of the box body, and the cooling component of the refrigeration device 5 can perform cooling operation on the energy storage battery pack inside the box body.

[0053] Among them, the refrigeration equipment 5 can be a water cooler, and its cooling component is a water cooling coil. By arranging the refrigeration equipment 5 outside the box, extending the water cooling coil into the box, and making the water cooling coil contact with the energy storage battery pack, the energy storage battery pack can be cooled.
