[0031] DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model. In the present utility model, unless otherwise specified, the orientation terms such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0033] Thermal management has always been the focus of new energy vehicles; as the energy density and power density of the power batteries of new energy vehicles are getting higher and higher, the heat generation of the batteries increases, and the heat dissipation system with characteristics such as fast cooling speed and high heat transfer coefficient has gradually become particularly important. In related technologies, a heat dissipation structure is often provided at the bottom of the battery pack for heat dissipation. This heat dissipation structure can only dissipate heat from the bottom of the battery pack well, and has poor heat dissipation ability for the middle part of the battery pack, resulting in too high a temperature in the middle of the battery pack and prone to thermal runaway.

[0034] In view of this, the present utility model proposes a direct cooling component Figures 1 to 6 FIG. is a schematic structural diagram of an embodiment of the direct cooling component provided by the present utility model. The direct cooling component will be described in detail below in conjunction with the main drawings.

[0035] For the convenience of description, taking Figure 1 the first direction in as an example, the first direction is the length direction of the cooling plate 101, the second direction is the height direction of the cooling plate 101, and the third direction is the width direction of the cooling plate 101.

[0036] Please refer to Figure 1 and Figure 2, The cooling group includes a plurality of cooling plates 101 and a liquid pipe assembly a. The plurality of cooling plates 101 are arranged at intervals in a direction perpendicular to the length of the cooling plate 101. A cooling cavity 102 is formed between two adjacent cooling plates 101. The cooling cavity 102 is used to accommodate a plurality of batteries 200. Each cooling plate 101 includes a plurality of bending segments 103, and the bending segments 103 are used to fit the outer surface of the battery 200. Among them, each cooling plate 101 includes a liquid inlet end 104, a liquid outlet end 105 and a cooling channel. The cooling channel is communicated with the liquid inlet end 104 and the liquid outlet end 105. The liquid pipe assembly a is communicated with the cooling plate 101 through a pipe joint b. Among them, the pipe joint b includes a plate end connector b1, a pipe end connector b2 and a threaded fixing member b3. The plate end connector b1 is fixed to the liquid inlet end 104 or the liquid outlet end 105. The pipe end connector b2 is fixed to the liquid pipe assembly a. The plate end connector b1 and the pipe end connector b2 are threadedly connected through the threaded fixing member b3.

[0037] In the technical solution of the present utility model, a cooling cavity 102 is formed between two adjacent cooling plates 101. The cooling cavity 102 is used to accommodate the battery 200. The cooling plates 101 cool the battery 200 from two sides, and the cooling efficiency is high. At the same time, the cooling plate 101 is provided with a plurality of bending segments 103, and the plurality of bending segments 103 are adapted to the outer peripheral surface of the battery 200, so that the cooling plate 101 can be in close contact with the battery 200, thereby improving the cooling effect. At the same time, a pipe joint b is provided between the cooling plate 101 and the liquid pipe assembly a. The pipe joint b includes a plate end connector b1, a pipe end connector b2 and a threaded fixing member b3. The plate end connector b1 is fixed to the liquid inlet end 104 or the liquid outlet end 105. The pipe end connector b2 is fixed to the liquid pipe assembly a. The plate end connector b1 and the pipe end connector b2 are threadedly connected through the threaded fixing member b3, which improves the pressure resistance and sealing performance of the direct cooling component 100.

[0038] In some embodiments, each cooling plate 101 further includes a first end 106, and the liquid inlet end 104 and the liquid outlet end 105 are located at the first end 106. With such a setting, the length of the cooling channel can be extended, so that the cooling medium in the cooling channel flows through the same battery 200 at least twice successively, improving the cooling efficiency and avoiding the occurrence of thermal runaway.

[0039] Further, a plurality of cooling plates 101 are arranged at intervals in the third direction, and a plurality of batteries 200 are arranged at intervals in the first direction in the cooling cavity 102. In some embodiments, among the plurality of batteries 200 in each cooling cavity 102, every two adjacent batteries 200 are in close contact with each other. With such an arrangement, space can be saved, more batteries 200 can be placed, and the capacity of the cooling cavity 102 can be increased. In some other embodiments, among the plurality of batteries 200 in each cooling cavity 102, a gap groove is formed between every two adjacent batteries 200 to prevent adjacent batteries 200 from contacting each other, thereby reducing the probability of temperature transfer between the batteries 200. At the same time, the gap groove can also have a certain cooling effect (air cooling), improving the cooling efficiency of the cold area components.

[0040] It should be noted that during the cooling process, as the cooling medium flows, the temperature of the cooling medium continuously rises, that is, the temperature of the cooling matrix at the liquid inlet end 104 is higher than the temperature of the cooling matrix at the liquid outlet end 105. In this embodiment, the cooling medium in the cooling channel can flow through the same battery 200 at least twice successively. The battery 200 that is first flowed through by the cooling medium is the last to be flowed through by the cooling medium again, and vice versa. The battery 200 that is last flowed through by the cooling medium is the first to be flowed through by the cooling medium again. Since the temperature of the cooling medium gradually rises during the cooling process and its cooling effect gradually decreases, the battery 200 with a better cooling effect when the cooling medium first flows through has a worse cooling effect when the cooling medium flows through it the second time, and vice versa. Thus, the cooling effects of the round-trip cooling are superimposed, which can balance the cooling effects obtained by the batteries 200 in the same column, keep the plurality of batteries 200 in an isothermal state, avoid the phenomenon of local high temperature, and improve the service life of the plurality of batteries 200.

[0041] It should be noted that the direct cooling assembly 100 provided by the present utility model can be applicable to various different models of batteries 200. In some embodiments, when the battery 200 to be cooled is a cylindrical battery 200, the bending section 103 is arc-shaped. In some other embodiments, when the battery 200 to be cooled is a square battery 200, the bending section 103 is square. In some embodiments, when the battery 200 to be cooled is a long blade battery 200, the bending section 103 is rectangular.

[0042] It should be noted that the type of the cooling medium in the above embodiments is not limited and can be selected according to the actual application situation. For example, the cooling medium can be lubricating oil, water, cold air, alcohol compounds, etc.
