[0006] Furthermore, a heat conducting sleeve is wrapped on the outer side wall of the battery body. The heat conducting sleeve is located between the battery body and the corrugated plate, and the heat conducting sleeve is adhesively connected to the corrugated plate.

[0007] Furthermore, the flow holes are divided into upper and lower parts. Both the liquid inlet pipe and the liquid outlet pipe are C-shaped and are correspondingly arranged with the upper and lower ends of the flow holes.

[0008] Furthermore, a protective frame is fixedly connected to the outer end of the fixing frame. A heat dissipator is fixedly connected to the outer end of the protective frame. An air outlet is formed at the other end of the protective frame, and the heat dissipator dissipates heat from the surface of the flow pipe through air cooling.

[0009] Furthermore, the contact area between the side surfaces of both ends of the corrugated plate and the side surfaces of both ends of the battery bodies is not less than one-third of the side surface area of the battery bodies, and the contact area between the battery body in the middle of the corrugated plate and the corrugated plate is not less than two-thirds.

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0021] Please refer to Figures 1-5The utility model provides a technical solution: a battery assembly, including a fixed frame 4, in which a battery body 3 is arranged in an array, a pressing sheet 13 is placed on the upper end of the battery body 3, a corrugated plate 5 is arranged on the outer side of the battery body 3, a flow hole 11 is opened on the inner side of the corrugated plate 5, both ends of the corrugated plate 5 are fixed on the fixed frame 4, and both ends of the fixed frame 4 are fixedly connected with a liquid guide plate 10, wherein the outer side of the liquid guide plate 10 at one end is connected with a liquid inlet pipe 6, wherein the outer side of the liquid guide plate 10 at the other end is connected with a liquid outlet pipe 9, a flow pipe 7 is connected between the liquid inlet pipe 6 and the liquid outlet pipe 9, and a water pump 8 is fixedly connected to the flow pipe 7; the battery body 3 The overall rectangular shape is staggered and arranged in a fixed frame 4. A pressing sheet 13 is placed at the upper end of the battery body 3. A battery pack is formed by combining the positive and negative electrodes at the upper and lower ends. A corrugated plate 5 is provided on the side of the battery body 3. The corrugated plate 5 contacts the battery body 3. A flow hole 11 is provided in the corrugated plate 5. A coolant flows in the flow hole 11. The coolant enters from the liquid inlet pipe 6 and flows out from the liquid outlet pipe 9. The heat generated by the battery body 3 is then taken away by the flow of the coolant. When the overall temperature of the battery body 3 is higher than the set temperature, the water pump 8 starts to work, and the internal coolant is driven to circulate through the water pump 8, thereby achieving the effect of cooling the battery body 3. Figure 3 It can be seen that the independent cooling effect can quickly reduce the temperature of the battery body 3 to a stable temperature range, thereby allowing the battery body 3 to reach the optimal range of use.

[0022] like Figure 5 As shown, the outer wall of the battery body 3 is wrapped with a heat-conducting sleeve 12, and the heat-conducting sleeve 12 is located between the battery body 3 and the corrugated plate 5, and the heat-conducting sleeve 12 is bonded and connected to the corrugated plate 5. The heat-conducting sleeve 12 is sleeved on the outer side of each battery body 3, and the heat generated by the battery body 3 can be quickly discharged through the heat-conducting sleeve 12, and then conducted to the corrugated plate 5 through the heat-conducting sleeve 12, and discharged through the coolant in the corrugated plate 5, thereby accelerating the heat transfer effect of the single battery body 3.

[0023] like Figure 4 As shown, the flow hole 11 is divided into two parts, and the liquid inlet pipe 6 and the liquid outlet pipe 9 are both C-shaped and correspond to the upper and lower ends of the flow hole 11; the flow hole 11 with upper and lower parts is opened in the corrugated plate 5. After the flow hole 11 is divided into two parts, the flow speed of the internal coolant can be increased, and the C-shaped setting of the liquid inlet pipe 6 and the liquid outlet pipe 9 can correspond to the flow holes 11 at the upper and lower ends, thereby improving the heat absorption efficiency of the corrugated plate 5.

[0024] like Figure 1As shown in the figure, the outer end of the fixed frame 4 is fixedly connected with a protective frame 1. The outer end of the protective frame 1 is fixedly connected with a radiator 2. An air outlet is provided at the other end of the protective frame 1. The radiator 2 dissipates heat from the surface of the air-cooled convection pipe 7 through air cooling; the protective frame 1 is fixed on the outside of the fixed frame 4. The overall liquid inlet pipe 6, convection pipe 7, water pump 8 and liquid outlet pipe 9 can be protected by the protective frame 1. A radiator 2 is fixedly connected to the lower outer side of the protective frame 1. When the internal water pump 8 operates, the radiator 2 starts to work, and the heat on the surfaces of the liquid inlet pipe 6, convection pipe 7 and liquid outlet pipe 9 is blown to the air outlet of the protective frame 1 by air cooling, thereby improving the heat dissipation of the coolant.

[0025] As Figure 4 and Figure 5 shown in the figure, the contact area between the sides of the two end waveform plates 5 and the sides of the two end battery bodies 3 is set to be not less than one-third of the side area of the battery body 3, and the contact area between the battery body 3 in the middle of the waveform plate 5 and it is set to be not less than two-thirds; the contact area between the two end battery bodies 3 and the waveform plate 5 is set to be not less than one-third of the side of the battery body 3, while the contact area between the battery body 3 in the middle inside and the waveform plate 5 is set to be not less than two-thirds of the side of the battery body 3. Increasing the contact area in this way can increase the absorption and transfer of heat, improve the efficiency of heat transfer, and thus achieve the effect of rapid cooling.

[0026] As Figure 1 shown in the figure, the protective frame 1 is integrally formed and bent from an aluminum alloy plate. The heat of the air inside the periphery of the fixed frame 4 can be absorbed and transferred through the aluminum alloy plate, thereby further improving the heat dissipation. Moreover, the aluminum alloy plate has a protective effect and is light in weight.

[0027] As Figure 5 shown in the figure, the outer end of the waveform plate 5 is coated with insulating glue, and the heat conduction sleeve 12 and the waveform plate 5 are adhesively bonded with heat conduction glue; the insulating glue coated on the outer end of the waveform plate 5 can prevent the battery body 3 from leaking electricity, thereby avoiding electrical conduction. Moreover, the heat conduction sleeve 12 and the waveform plate 5 are adhesively connected through heat conduction glue, which can not only improve the connection stability between the battery bodies 3, but also improve the heat transfer. Embodiment

[0028] An electrical device includes the battery assembly of any one of the above. The electrical device can maintain a stable operating state when powered by the above battery assembly. When the operating temperature increases, it can quickly cool down, and while the cooling is stable, it can dissipate heat, preventing heat from staying around the battery assembly.

[0029] The above are only the preferred embodiments of the present utility model, and do not impose any formal limitations on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the above-disclosed technical content. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
