[0034] The following is for reference. Figures 1 to 4 This invention describes a heat dissipation assembly and a battery according to embodiments of the present invention.

[0035] According to a first aspect embodiment of the present invention, the heat dissipation assembly is installed within a battery housing 400. The sidewall of the housing 400 may have multiple through holes through which the heat dissipation fins 202 of the heat dissipation component 200 pass. Furthermore, the battery may also include a cell module disposed within the housing 400.

[0036] like Figures 1 to 4 As shown, the heat dissipation assembly includes a heat-conducting base plate 100 and at least one heat sink 200.

[0037] The heat-conducting base plate 100 has at least one heat-conducting connecting plate 101 connected to its edge. For example, four heat-conducting connecting plates 101 can be provided, each connected to one of the four perimeters of the heat-conducting base plate 100. The heat-conducting connecting plates 101 extend along the edge of the heat-conducting base plate 100 to which they are connected, for example, extending to both ends of the edge of the heat-conducting base plate 100 to which they are connected. The thickness direction of the heat-conducting connecting plate 101 can be parallel to the edge of the heat-conducting base plate 100 to which it is connected. For example, when the heat-conducting base plate 100 is attached to the bottom of the housing 400, the thickness direction of the heat-conducting connecting plate 101 can be parallel to the thickness direction of the corresponding side wall of the housing 400. The heat-conducting connecting plate 101 is provided with multiple clearance openings 102, which can be arranged along the length direction of the heat-conducting connecting plate 101 and can penetrate along the thickness direction of the heat-conducting connecting plate 101. When the heat-conducting base plate 100 is attached to the bottom end inside the housing 400, the clearance openings 102 can be aligned with the through holes on the corresponding side wall of the housing 400. When the battery cell module is placed inside the housing 400, the battery cell module can be attached to the upper surface of the heat-conducting base plate 100 to facilitate the transfer of heat to the heat-conducting base plate 100.

[0038] At least one heat sink 200 is provided. For example, when four heat-conducting connecting plates 101 are provided, the four heat sinks 200 can be respectively provided for the four heat-conducting connecting plates 101. The heat sink 200 includes a heat sink connecting plate 201 and a plurality of heat sinks 202. The heat sink connecting plate 201 is attached to the inner side of the corresponding heat-conducting connecting plate 101 and is detachably connected to the heat-conducting connecting plate 101. For example, the heat sink connecting plate 201 can be connected to or snapped onto the heat-conducting connecting plate 101 by fasteners 203. The plurality of heat sinks 202 are provided on the outer side of the heat sink connecting plate 201 and are respectively provided through a plurality of relief openings 102 and through through holes on the corresponding side wall of the housing 400.

[0039] It should be noted that the inner surface of the heat-conducting connecting plate 101, the inner surface of the heat-dissipating connecting plate 201, and the inner surface of the housing 400 refer to the surface facing the battery cell module after the battery cell module is placed inside the housing 400. The outer surface of the heat-conducting connecting plate 101, the outer surface of the heat-dissipating connecting plate 201, and the outer surface of the housing 400 refer to the surface facing away from the battery cell module after the battery cell module is placed inside the housing 400.

[0040] In this invention, when assembling the battery, firstly, the heat-conducting base plate 100 of the heat dissipation component is attached to the bottom surface inside the battery casing 400. Then, the heat dissipation component 200 is moved above the heat-conducting base plate 100, and the surface of the heat dissipation connecting plate 201 is made parallel to the surface of the heat-conducting connecting plate 101, so that multiple heat dissipation fins 202 are aligned with multiple clearance openings 102. Then, the heat dissipation component 200 is moved outward so that the heat dissipation connecting plate 201 is attached to the inner side surface of the heat-conducting connecting plate 101, and multiple heat dissipation fins 202 are respectively inserted through multiple clearance openings 102 and multiple through holes on the side wall of the casing 400. Finally, the heat dissipation connecting plate 201 is connected to the heat-conducting connecting plate 101. The operation is simple, time-saving and labor-saving.

[0041] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the heat dissipation assembly also includes at least one heat-conducting side plate 300. The heat-conducting side plate 300 is connected to the top of the heat-conducting connecting plate 101. The outer side of the heat-conducting side plate 300 is used to fit against the inner side of the battery casing 400, and the inner side of the heat-conducting side plate 300 is used to fit against the outer side of the battery cell module. For example, when four heat-conducting connecting plates 101 are provided and the four heat-conducting connecting plates 101 are respectively connected to the four peripheral edges of the heat-conducting base plate 100, the heat-conducting side plates 300 can also be provided as four, and the four heat-conducting side plates 300 can be respectively located at the four peripheral edges of the heat-conducting base plate 100, and the four heat-conducting side plates 300 are respectively connected to the top of the four heat-conducting connecting plates 101.

[0042] In this embodiment, a heat-conducting side plate 300 is provided, which can transfer the heat of the battery cell module from the periphery of the battery cell module to the heat-conducting side plate 300, and then part of it is transferred to the heat-conducting connecting plate 101 and dissipated through the heat sink 200, and part of it is directly transferred to the side wall of the housing 400 and dissipated through the side wall of the housing 400, so that the heat dissipation effect of the battery is better.

[0043] It should be noted that the heat-conducting base plate 100, heat-conducting side plate 300, heat-conducting connecting plate 201 and heat sink 202 of the heat dissipation component can all be made of heat-conducting materials, which will not be described in detail here.

[0044] In some embodiments of this utility model, such as Figures 1 to 4As shown, a plurality of first heat dissipation grooves 301 are formed on the outer surface of the heat-conducting side plate 300. The plurality of first heat dissipation grooves 301 are arranged at intervals along the length direction of the heat-conducting connecting plate 101, and the top end of the first heat dissipation groove 301 is through-hole. For example, the plurality of first heat dissipation grooves 301 can be directly formed on the outer surface of the heat-conducting side plate 300, or the heat-conducting side plate 300 can be set as a bent plate structure, and the heat-conducting side plate 300 forms the first heat dissipation grooves 301 by bending. In this embodiment, by providing a plurality of first heat dissipation grooves 301, some of the heat between the heat-conducting side plate 300 and the side wall of the housing 400 can be conducted through the air flow in the first heat dissipation grooves 301, thereby improving the heat dissipation effect of the heat dissipation component.

[0045] In some embodiments of this utility model, such as Figures 1 to 4 As shown, multiple first heat dissipation grooves 301 are respectively located above multiple relief openings 102, and the bottom end of the first heat dissipation groove 301 is connected to the relief opening 102. For example, the bottom end of the first heat dissipation groove 301 can be through-hole, and the top end of the relief opening 102 can be through-hole, so that the bottom end of the first heat dissipation groove 301 is connected to the relief opening 102. In this embodiment, the bottom end of the first heat dissipation groove 301 is connected to the relief opening 102, which makes the flow of hot air in the first heat dissipation groove 301 better, and the hot air in the first heat dissipation groove 301 can directly flow into the relief opening 102 at the bottom end of the first heat dissipation groove 301 and be directly absorbed by the heat sink 202, thereby making the heat dissipation effect of the heat dissipation component better.

[0046] In some embodiments of this utility model, such as Figures 1 to 4 As shown, a plurality of second heat dissipation grooves 302 are formed on the inner surface of the heat-conducting side plate 300. The plurality of second heat dissipation grooves 302 are arranged at intervals along the length direction of the heat-conducting connecting plate 101, and the top of the second heat dissipation grooves 302 are through. For example, the plurality of second heat dissipation grooves 302 can be directly formed on the inner surface of the heat-conducting side plate 300, or the heat-conducting side plate 300 can be set as a bent plate structure, and the second heat dissipation grooves 302 are formed by bending the heat-conducting side plate 300. In this embodiment, by setting a plurality of second heat dissipation grooves 302, part of the heat between the heat-conducting side plate 300 and the outer surface of the battery cell module can be conducted through the air flow in the second heat dissipation grooves 302, thereby improving the heat dissipation effect of the heat dissipation component.

[0047] In some embodiments of this utility model, such as Figures 1 to 4As shown, the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat-conducting connecting plate 101, and the bottom end of the second heat dissipation groove 302 is through-hole. The inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat-conducting connecting plate 101, facilitating the through-hole penetration of the bottom end of the second heat dissipation groove 302. In this embodiment, the through-hole penetration of the bottom end of the second heat dissipation groove 302 improves the airflow within it, allowing the hot air to flow to the vicinity of the heat-conducting base plate 100 and be absorbed by it, thus enhancing the heat dissipation effect of the heat dissipation assembly.

[0048] It should be noted that the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat-conducting connecting plate 101, that is, the projection along the length direction of the heat-conducting connecting plate 101. The inner side of the heat-conducting side plate 300 is located directly above the inner side of the inner side of the heat-conducting connecting plate 101.

[0049] In some embodiments of this utility model, such as Figures 1 to 4 As shown, the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat dissipation connecting plate 201. In this embodiment, this arrangement allows the heat dissipation connecting plate 201 to be located between the bottom surface of the heat-conducting side plate 300 and the top surface of the heat-conducting base plate 100, thereby preventing the battery cell module from touching the heat dissipation connecting plate 201 and damaging both the battery cell module and the heat dissipation connecting plate 201. Furthermore, the inner side of the heat dissipation connecting plate 201 has a certain amount of heat dissipation space, which further improves the heat dissipation effect of the heat dissipation component.

[0050] It should be noted that the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat dissipation connecting plate 201, that is, the projection along the length of the heat-conducting connecting plate 101. The inner side of the heat-conducting side plate 300 is located directly above the inner side of the heat dissipation connecting plate 201.

[0051] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first heat dissipation groove 301 and the second heat dissipation groove 302 are arranged alternately along the length of the heat-conducting connecting plate 101. This arrangement can prevent the heat-conducting side plate 300 from being too thin at a certain position, thus reducing the structural strength and minimizing the risk of damage to the heat-conducting side plate 300.

[0052] In some embodiments of this utility model, such as Figures 1 to 4 As shown, four heat-conducting connecting plates 101 are provided and located on the four periphery of the heat-conducting base plate 100, and four heat sinks 200 are provided accordingly. The heat sink connecting plate 201 of each heat sink 200 is respectively attached to the inner side of each heat-conducting connecting plate 101. In this embodiment, this arrangement makes the heat conduction and heat dissipation effect of the heat dissipation component better.

The side wall of the housing 400 is provided with a plurality of through holes, the heat dissipation assembly is disposed inside the housing 400, and a plurality of heat dissipation fins 202 are respectively disposed through the plurality of through holes.

[0054] According to the battery of the present invention, by adopting the heat dissipation component of the first aspect of the present invention, when assembling the battery, firstly, the heat-conducting base plate 100 of the heat dissipation component is attached to the bottom surface inside the battery housing 400. Then, the heat dissipation component 200 is moved above the heat-conducting base plate 100, and the plate surface of the heat dissipation connecting plate 201 is made parallel to the plate surface of the heat-conducting connecting plate 101, so that multiple heat dissipation fins 202 are aligned with multiple clearance openings 102. Then, the heat dissipation component 200 is moved outward so that the heat dissipation connecting plate 201 is attached to the inner side surface of the heat-conducting connecting plate 101, and multiple heat dissipation fins 202 are respectively inserted through multiple clearance openings 102 and multiple through holes on the side wall of the housing 400. Finally, the heat dissipation connecting plate 201 and the heat-conducting connecting plate 101 are connected. The operation is simple, time-saving and labor-saving.

[0055] It should be noted that since the battery can adopt all the technical solutions of the heat dissipation component of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment. These additional beneficial effects will not be elaborated here.

[0056] It is understood that the battery according to the present invention may further include a cell module, which is installed inside the housing 400 and can be attached to the upper surface of the heat-conducting base plate 100. Furthermore, other configurations and operations of the battery according to the present invention are known to those skilled in the art and will not be described in detail here.
