Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery packs, and in particular to a heat dissipation plate. Background Art
[0002] Conventional battery modules include two side plates and two end plates, which fit the single cells together over a large area and are fixed inside the side plates and end plates to form a battery module. The single cells generate heat when working, and the heat cannot be discharged because the single cells fit together. Under harsh conditions, the single cells will expand significantly, and there is no extra space left after the single cells are grouped together, so they are all in a state of fitting together, causing the single cells to squeeze each other, affecting their service life. Utility Model Content
[0003] The utility model aims to provide a heat dissipation plate to solve the problem that the heat of a single battery is difficult to be discharged and the batteries are squeezed against each other.
[0004] In order to achieve the above object, the basic scheme of the utility model is as follows:

[0006] Compared with the prior art, the heat dissipation plate of the present application has the following beneficial effects:
[0007] The heat sink of the present application is placed between the single cells when in use, which can not only prevent the single cells from squeezing each other when they heat up and expand, but also prevent the heat from being transferred to each other, thereby increasing the service life of the single cells. The heat sink of the present application improves the heat dissipation efficiency by providing heat dissipation channels and heat dissipation fins, and reduces the degree of deformation of the heat sink when it is squeezed by providing a support assembly.
[0008] Preferably, the support assembly includes a left support plate and a right support plate, one end of the left support plate is connected to the first plate body, and the other end is connected to the second plate body; one end of the right support plate is connected to the first plate body, and the other end is connected to the second plate body; the left support plate and the right support plate are connected to separate the heat dissipation channel, and a heat dissipation fin is arranged between adjacent left support plates and right support plates.
[0009] Beneficial effect: The arrangement of the left support plate and the right support plate increases the contact area between the first plate body, the second plate body and the heat dissipation channel, thereby improving the heat dissipation efficiency.
[0010] Preferably, the heat dissipation fins on the inner sides of the first plate body and the second plate body are staggered and arranged with equal intervals.
[0011] Beneficial effect: The staggered gap arrangement of the heat dissipation fins makes the heat dissipation more uniform and prevents local overheating.
[0012] Preferably, the left support plate and the right support plate are obliquely arranged between the first plate body and the second plate body, and the adjacent left support plates and the right support plates are mirror-arranged with the heat dissipation fins therebetween as a mirror surface.
[0013] Beneficial effect: The inclined arrangement of the left support plate and the right support plate improves the stability of the support and makes the heat sink less likely to be damaged.
[0014] Preferably, the surface of the heat dissipation fins is configured to be in a corrugated shape.
[0015] Beneficial effect: The surface of the heat dissipation fin is set to a corrugated shape, which increases the contact area between the heat dissipation fin and the heat dissipation channel and improves the heat dissipation efficiency.
[0016] Preferably, the support assembly, the heat sink fins, the first plate body, the second plate body and the connecting piece are all made of metal, and the heat sink is an integrally formed structure.
[0017] Beneficial effect: The heat sink is an integrated structure and is made of metal, so that the heat sink has a certain strength to resist the extrusion of the single battery.
[0018] Preferably, an adhesive layer is provided on the outer sides of the first plate body and the second plate body.
[0019] Beneficial effect: The setting of the adhesive layer connects the heat sink and the single battery, so that the heat generated by the single battery is transferred to the heat sink in the first time and then dissipated from the heat dissipation channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is further described in detail through specific implementation methods:
[0024] The reference numerals in the drawings of the specification include: a first plate body 1 , a second plate body 2 , a connector 3 , a heat dissipation channel 4 , a heat dissipation fin 5 , a left support plate 6 , a right support plate 7 , and an adhesive layer 8 .
[0025] As attached Figure 1-2 As shown, this embodiment shows a heat sink, including a first plate body 1 and a second plate body 2 arranged parallel to each other, and connecting members 3 are respectively arranged on both sides of the first plate body 1 and the second plate body 2, and the first plate body 1 and the second plate body 2 are connected by the connecting member 3.
[0026] Specifically, the first plate body 1 and the second plate body 2 have the same shape and size, both of which are rectangular plates. The connecting member 3 is in the shape of a strip with an arc-shaped longitudinal interface, and the length of the connecting member 3 is the same as the width of the first plate body 1 and the second plate body 2. The upper end of the connecting member 3 is connected to the first plate body 1, and the lower end of the connecting member 3 is connected to the second plate body 2.
[0027] There is a certain distance between the first plate body 1 and the second plate body 2, so a heat dissipation channel 4 is formed between the first plate body 1 and the second plate body 2. Heat dissipation fins 5 are arranged on the inner sides of the first plate body 1 and the second plate body 2, and the heat dissipation fins 5 are located in the heat dissipation channel 4; a support assembly is arranged between the first plate body 1 and the second plate body 2.
[0028] The support assembly can prevent the heat sink from excessive deformation when it is squeezed.
[0029] The support assembly includes a left support plate 6 and a right support plate 7. One end of the left support plate 6 is connected to the first plate body 1, and the other end is connected to the second plate body 2; one end of the right support plate 7 is connected to the first plate body 1, and the other end is connected to the second plate body 2; the connected left support plate 6 and right support plate 7 separate the heat dissipation channel 4, and a heat dissipation fin 5 is arranged between the adjacent left support plate 6 and right support plate 7. At the same time, the arrangement of the left support plate 6 and the right support plate 7 increases the contact area between the first plate body 1 and the second plate body 2 and the heat dissipation channel 4. The first plate body 1 and the second plate body 2 can conduct heat to the left support plate 6 and the right support plate 7, and then dissipate it through the heat dissipation channel 4, thereby improving the heat dissipation efficiency.
[0030] Specifically, the lengths of the left support plate 6 , the right support plate 7 and the heat dissipation fins 5 are the same as the widths of the first plate body 1 and the second plate body 2 .
[0031] In consideration of uniform heat dissipation, the heat dissipation fins 5 on the inner sides of the first plate body 1 and the second plate body 2 in this embodiment are staggered and arranged with equal intervals.
[0032] The left support plate 6 and the right support plate 7 are tilted between the first plate body 1 and the second plate body 2. The adjacent left support plates 6 and right support plates 7 are mirrored with the heat sink fins 5 therebetween. The tilted arrangement of the left support plate 6 and the right support plate 7 improves the stability of the support, making it less likely for the heat sink to be damaged by squeezing.
[0033] In some embodiments, the surface of the heat dissipation fin 5 is configured to be in a corrugated shape (not shown in the figure). The surface of the heat dissipation fin 5 is configured to be in a corrugated shape to increase the contact area between the heat dissipation fin 5 and the heat dissipation channel 4 and improve the heat dissipation efficiency.
[0034] Among them, the support assembly, the heat sink fins 5, the first plate body 1, the second plate body 2 and the connecting member 3 are all made of metal, and the heat sink is an integrated structure, so that the heat sink has a certain strength to resist the extrusion of the single battery.
[0035] like Figure 3 As shown, in another embodiment, an adhesive layer 8 is disposed on the outer sides of the first plate body 1 and the second plate body 2. The adhesive layer 8 is disposed so that the heat sink and the single battery are tightly connected, and the heat generated by the single battery can be directly transferred to the heat sink, thereby improving the heat transfer efficiency. Specifically, the adhesive layer 8 uses 3M double-sided adhesive.
[0036] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
