[0026] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] In the prior art, see Figure 1 The energy storage device 100 includes a shell a10 and a battery assembly a20. The shell a10 is provided with a receiving cavity a10a, and the battery assembly a20 is provided in the receiving cavity a10a. The shell a10 is installed on the wall 200, and the heat R generated by the energy storage device 100 is conducted to the wall 200 through the shell a10. Usually, the user's wall 200 is not completely flat, resulting in a gap between the shell a10 and the wall 200. Most of the heat generated by the energy storage device 100 accumulates in the shell a10, and only a small part of the heat is conducted to the wall 200 through the shell a10 and the gas medium between the shell a10 and the wall 200. As a result, the shell a10 is very hot, which seriously affects the operation of the energy storage device 100 and causes a poor user experience.

[0029] This utility model provides an energy storage device, please refer to Figure 2-Figure 5 The energy storage device 100 includes a shell 10, a battery assembly 20 and a thermally conductive adhesive (not shown). The shell 10 is provided with a accommodating cavity 10a, the battery assembly 20 is arranged in the accommodating cavity 10a, and the thermally conductive adhesive is located between the first side wall 10b and the battery assembly 20. One end of the thermally conductive adhesive is attached to the first side wall 10b, and the other end of the thermally conductive adhesive is attached to the battery assembly 20. When the battery assembly 20 generates heat, the heat is conducted to the shell 10 through the thermally conductive adhesive, thereby achieving heat dissipation and further improving the heat dissipation performance of the energy storage device 100. It should be noted that when the battery assembly 20 generates heat by supplying power to an external device or when an external power supply charges the battery assembly 20, the battery assembly 20 will have a partial loss of electrical energy, and the lost electrical energy is usually converted into internal energy.

[0030] The accommodating cavity 10a has a first sidewall 10b and a second sidewall 10c, with the first sidewall 10b and the second sidewall 10c being disposed opposite each other. Two battery assemblies 20 and two thermally conductive adhesives are disposed at intervals. One thermally conductive adhesive is attached to the first sidewall 10b and one battery assembly 20 at its ends, while another thermally conductive adhesive is attached to the second sidewall 10c and another battery assembly 20 at its ends. A heat dissipation channel 20a is formed between the two battery assemblies 20 to provide heat dissipation space for the battery assemblies 20.

[0031] The outer surface of the shell 10 is also provided with a plurality of heat dissipation fins 11, which can increase the heat dissipation area of ​​the shell 10, thereby increasing the heat dissipation effect of the shell 10, so that the heat of the battery assembly 20 is transferred to the shell 10 faster, and the battery assembly 20 is effectively cooled.

[0032] The housing 10 is further provided with an air inlet and an air outlet, both of which are connected to the heat dissipation channel 20a, and the air inlet and the air outlet are arranged opposite to each other. By blowing gas into the air inlet, the gas passes through the heat dissipation channel 20a and is discharged from the air outlet, which helps to reduce the resistance to gas circulation and improve the heat dissipation performance of the energy storage device 100.

[0033] The outer surface of the housing 10 is recessed toward the accommodating cavity 10a to form a primary heat dissipation channel 10e. This elliptical channel 10e is surrounded by a plurality of heat dissipation fins 11, with heat dissipation gaps 11a between adjacent heat dissipation fins 11. The housing 10 is also provided with an air guide channel 10d, which connects to the air outlet and directs air from the air outlet toward the primary heat dissipation channel 10e. Furthermore, the opening of the heat dissipation gap 11a faces the air guide channel 10d, directing air discharged from the air outlet toward the primary heat dissipation channel 10e, thereby accelerating heat dissipation from the plurality of heat dissipation fins 11.

[0034] In some embodiments, a single heat dissipating fin 11 has a guide portion (not shown) extending toward the main heat dissipating channel 10e. Along the direction of the gas blown out of the air guide channel 10d, the length of the guide portion extending toward the main heat dissipating channel 10e gradually increases. The guide portion is used to guide the gas discharged from the air guide channel 10d into the heat dissipating gap 11a between two adjacent heat dissipating fins 11, thereby enabling the heat dissipation of the heat dissipating fins 11 to be good.

[0035] The energy storage device 100 further includes a fan 30, see Figure 6 The fan 30 is installed on the shell 10, and the fan 30 corresponds to the air outlet. The fan 30 is used to extract the gas in the accommodating chamber 10a to the outside, so that the gas in the accommodating chamber 10a forms a gas exchange with the gas outside, thereby increasing the speed of the gas flow in the accommodating chamber 10a, further increasing the speed at which the heat of the battery assembly 20 is discharged to the outside, and improving the heat dissipation performance of the energy storage device 100.

[0036] In some embodiments, see Figure 6 The energy storage device 100 also includes a semiconductor refrigerator 40 and a plurality of cooling fins 50. The plurality of cooling fins 50 are arranged at the cold end of the semiconductor refrigerator 40. The plurality of cooling fins 50 and the cold end of the semiconductor refrigerator 40 both correspond to the air inlet. The semiconductor refrigerator 40 is used to cool the gas entering the accommodating chamber 10a from the air inlet, and the plurality of cooling fins 50 can increase the contact area with the gas entering the accommodating chamber 10a from the air inlet, so that the gas entering the accommodating chamber 10a from the air inlet is cooled, further improving the heat dissipation performance of the energy storage device 100.

[0037] In some embodiments, the energy storage device 100 further includes a heat pipe 60, see Figure 4 The heat pipe 60 has a tubular structure. One end of the heat pipe 60 is connected to the hot end of the semiconductor cooler 40, and the other end of the heat pipe 60 is connected to the shell 10. The heat pipe 60 is used to transfer the heat from the hot end of the semiconductor cooler 40 to the shell 10, thereby reducing the temperature inside the shell 10.

[0038] In an embodiment of the present application, an energy storage device 100 is provided. The energy storage device 100 includes a shell 10, a battery assembly 20, and a thermally conductive adhesive. The shell 10 is provided with a receiving cavity 10a, the receiving cavity having a first side wall 10b, the battery assembly 20 is provided in the receiving cavity 10a, and the thermally conductive adhesive is located between the first side wall 10b and the battery assembly 20. One end of the thermally conductive adhesive is attached to the first side wall 10b, and the other end of the thermally conductive adhesive is attached to the battery assembly 20. The thermally conductive adhesive is used to conduct the heat of the battery assembly 20 to the shell 10. When the battery assembly 20 generates heat, the heat is conducted to the shell 10 through the thermally conductive adhesive, thereby achieving heat dissipation and further improving the heat dissipation performance of the energy storage device 100. Compared with the prior art, the energy storage device 100 has good heat dissipation performance, which makes the energy storage device 100 have a longer service life, higher working efficiency and stronger stability.
