[0001] Cross Reference to Related Applications
[0002] This application claims the benefit of Korean Patent Application Nos. 10-2021-0056421, filed April 30, 2021, and 10-2022-0047511, filed April 18, 2022, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties.
[0003] The present disclosure relates to a heat dissipation assembly that effectively dissipates heat while preventing heat propagation between adjacent battery modules, and a battery pack including the same. BACKGROUND
[0004] As technology develops and the demand for mobile devices increases, the demand for secondary batteries as energy sources is rapidly increasing. In particular, secondary batteries have attracted considerable attention as energy sources for electric power-driven devices such as electric bicycles, electric vehicles, and hybrid electric vehicles, and as energy sources for mobile devices such as mobile phones, digital cameras, laptop computers, and wearable devices.
[0005] Small mobile devices use one or more battery cells per device, while medium or large devices such as vehicles require high power and large capacity. Therefore, medium or large battery modules using a plurality of battery cells electrically connected to each other are used.
[0006] Medium or large battery modules are preferably manufactured to have as small a size and weight as possible. Therefore, square batteries, pouch batteries, etc. that can be stacked at a high integration level and have a small weight relative to capacity are mainly used as battery cells of medium or large battery modules.
[0007] However, a battery pack of the related art includes a plurality of battery modules, and if thermal runaway occurs in a portion of the battery cells of each battery module to cause a fire or an explosion, heat or flames can be transferred to adjacent secondary batteries to cause a secondary explosion, etc. Therefore, more efforts are being made to prevent secondary fires or explosions.
[0008] Therefore, there is a need to develop a heat dissipation assembly and a battery pack including the same that can effectively dissipate generated heat while preventing heat transfer to adjacent battery modules when a portion of the battery modules in the battery pack catches fire or explodes.

[0041] Hereinafter, a battery pack including a heat dissipation assembly according to an embodiment of the disclosure will be described.
[0042] Figure 1 is a diagram briefly showing a pair of battery modules and a heat dissipation assembly included in a battery pack according to an embodiment of the disclosure.
[0043] Referring to Figure 1 , a battery pack according to an embodiment of the disclosure includes a heat dissipation assembly 100, in which the heat dissipation assembly 100 is located between a pair of adjacent battery modules 10 among a plurality of battery modules.
[0044] Here, the battery module 10 is not specifically shown in the drawing, but a plurality of battery cells (not shown) can be stacked in a predetermined direction and then mounted on a module frame to constitute the battery module. Here, since the plurality of battery cells (not shown) are not specifically limited in type, a pouch-shaped secondary battery or a square-shaped secondary battery can be used.
[0045] Further, in the present embodiment, one side surface of one of the pair of battery modules 10 can be in contact with a first heat insulating member 131 ( Figure 3 ), and one side surface of the other of the pair of battery modules 10 can be in contact with a second heat insulating member 135 ( Figure 3 ).
[0046] Therefore, according to the present embodiment, when a fire or an explosion occurs in a portion of the battery module, heat transfer between the adjacent battery modules 10 can be blocked by the heat insulating member 130 ( Figure 3 ) of the heat dissipation assembly 100, thereby preventing continuous fire or explosion due to heat propagation between the adjacent battery modules 10.
[0047] Further, an upper portion of one of the pair of battery modules 10 can be in contact with at least a portion of a first heat dissipation member 151 ( Figure 2 ), and an upper portion of the other of the pair of battery modules 10 can be in contact with at least a portion of a second heat dissipation member 155 ( Figure 2 ).
[0048] Thus, according to the present embodiment, when a fire or an explosion occurs in a portion of the battery module, heat generated in the adjacent battery modules 10 moves along the heat dissipation member 150 ( Figure 2 ) of the heat dissipation assembly 100, and thus, heat generated in the battery modules 10 can be effectively and rapidly dissipated.
[0049] Next, the heat dissipation assembly according to the embodiments of the present disclosure will be described in more detail.
[0050] Figure 2 is a perspective view showing the heat dissipation assembly of Figure 1 . Figure 3 is a front view of the heat dissipation assembly of Figure 1 . Figure 4 is a view showing a frame member included in the heat dissipation assembly of Figure 1 . Figure 5 is a view showing a heat insulating member and a heat dissipation member included in the heat dissipation assembly of Figure 1 .
[0051] Referring to Figure 2 and Figure 3, the heat dissipation assembly 100 according to the embodiment of the disclosure includes a frame member 110 including a first frame 111 and a second frame 115 connected to each other, in which inner surfaces of the first frame 111 and the second frame 115 are folded to face each other, a first thermal insulation member 131 attached to an outer surface of the first frame 111, a second thermal insulation member 135 attached to an outer surface of the second frame 115, a central thermal insulation member 170 located between the inner surface of the first frame 111 and the inner surface of the second frame 115, a first heat dissipation member 151 located between the inner surface of the first frame 111 and the central thermal insulation member 170, and a second heat dissipation member 155 located between the inner surface of the second frame 115 and the central thermal insulation member 170.
[0052] More specifically, referring to Figure 2 and Figure 4 , the frame member 110 can include the first frame 111 and the second frame 115 connected to each other. More specifically, the frame member 110 can be folded such that the inner surface of the first frame 111 and the inner surface of the second frame 115 face each other.
[0053] For example, the frame member 110 can have at least one hinge coupling part 119 formed between the first frame 111 and the second frame 115. Here, the hinge coupling part 119 can have a hinge coupling structure commonly used in the art.
[0054] Thereby, the first frame 111 and the second frame 115 are folded in a direction in which the inner surface of the first frame 111 and the inner surface of the second frame 115 face each other based on the hinge coupling part 119. In addition, the hinge coupling part 119 is located below the frame member 110 to prevent the heat dissipation member 150 and the central thermal insulation member 170 from being separated upward and downward.
[0055] Referring to Figure 4 , each of the first frame 111 and the second frame 115 can be a grid frame including at least one cross-shaped structure. However, the shape of the first frame 111 and the second frame 115 is not limited thereto and can include any shape capable of maintaining the rigidity of the frame member 110 in the embodiment.
[0056] In addition, in the frame member 110, first side surface parts 111a and 111b can be formed on both sides of the first frame 111, respectively, and second side surface parts 115a and 115b can be formed on both sides of the second frame 115, respectively. More specifically, the first side surface parts 111a and 111b can extend in the upward and downward direction based on the wide surface of the first frame 111, and the second side surface parts 115a and 115b can extend in the upward and downward direction based on the wide surface of the second frame 115.
[0057] More specifically, referring to Figure 3 and Figure 4 , the first side surface portions 111a and 111b of the first frame 111 can cover the side surfaces of the first heat insulating members 131 attached to the outer surface of the first frame 111. Also, the first side surface portions 111a and 111b of the first frame 111 can cover the side surfaces of the first heat dissipation members 151 and the central heat insulating member 170 located on the inner surface of the first frame 111.
[0058] Even in the case of the second side surface portions 115a and 115b of the second frame 115, they can similarly cover the side surfaces of the second heat insulating members 135 attached to the outer surface of the second frame 115. Also, the second side surface portions 115a and 115b of the second frame 115 can cover the side surfaces of the second heat dissipation members 155 and the central heat insulating member 170 located on the inner surface of the second frame 115.
[0059] Thereby, the frame member 110 can cover the side surfaces of the heat insulating members 130, the heat dissipation members 150, and the central heat insulating member 170 located on the inner or outer surfaces of the first frame 111 and the second frame 115, thereby preventing the heat insulating members 130, the heat dissipation members 150, and the central heat insulating member 170 from being separated left and right and protecting them from external impact.
[0060] Referring to Figure 4 , the frame member 110 can have at least one protrusion 113 formed on the inner surface of at least one of the first frame 111 and the second frame 115. For example, as shown in Figure 4 , the protrusion 113 can be formed only on the inner surface of the first frame 111. However, the present application is not limited thereto, and the protrusion 113 can be formed on the inner surface of the second frame 115, or can be formed on the inner surfaces of the first frame 111 and the second frame 115, respectively.
[0061] Here, the protrusion 113 can pass through the first heat dissipation members 151, the second heat dissipation members 155, and the central heat insulating member 170. More specifically, the first heat dissipation members 151, the second heat dissipation members 155, and the central heat insulating member 170 can be pre-formed with holes into which the protrusion 113 can be fitted.
[0062] Accordingly, the frame member 110 can more stably fix the heat dissipation members 150 and the central heat insulating member 170 located on the inner surfaces of the first frame 111 and the second frame 115 within the frame member 110.
[0063] Further, the frame member 110 can be made of a material such as polycarbonate-acrylonitrile-butadiene-styrene (PC-ABS), polybutylene terephthalate (PBT), or polypropylene (PP). However, the material of the frame member 110 is not limited thereto, and in the present embodiment can include any material that has low thermal conductivity while maintaining the rigidity of the frame member 110.
[0064] Referring to Figure 2 , Figure 3 and Figure 5 (a), the thermal insulation member 130 can include a first thermal insulation member 131 connectable to an outer surface of the first frame 111 and a second thermal insulation member 135 connectable to an outer surface of the second frame 115.
[0065] Here, the first thermal insulation member 131 can extend along the outer surface of the first frame 111, but can extend to the first side surface portions 111a and 111b. Further, the second thermal insulation member 135 extends along the outer surface of the second frame 115, but can extend to the second side surface portions 115a and 115b.
[0066] Further, the thermal insulation member 130 can be made of silicon oxide. For example, the silicon oxide can be made of a material such as glass fiber. However, the material of the thermal insulation member 130 is not limited thereto, and in the present embodiment can include any material that has high thermal insulation performance.
[0067] Thereby, according to the present embodiment, the thermal insulation member 130 can block heat transfer between the adjacent battery modules 10( Figure 1 ).
[0068] Referring to Figure 2 , Figure 3 and Figure 5 (b), the central thermal insulation member 170 can be located between the inner surface of the first frame 111 and the inner surface of the second frame 115. More specifically, the central thermal insulation member 170 can be located between the first heat dissipation member 151 and the second heat dissipation member 155.
[0069] Here, the width of the central thermal insulation member 170 can be greater than the width of the thermal insulation member 130. More specifically, the width of the central thermal insulation member 170 can be greater than the width of the first thermal insulation member 131 or the width of the second thermal insulation member 135.
[0070] For example, the width of the central thermal insulation member 170 can be twice the width of the first thermal insulation member 131 or the width of the second thermal insulation member 135. However, the width of the central thermal insulation member 170 is not limited thereto, and in the present embodiment can include any width sufficient to block heat transfer between the first heat dissipation member 151 and the second heat dissipation member 155.
[0071] In addition, the central thermal insulation member 170 can be made of silicon oxide. For example, the silicon oxide can be made of a material such as glass fiber. However, the material of the central thermal insulation member 170 is not limited thereto, and can include any material having high thermal insulation performance in the present embodiment.
[0072] Thereby, according to the present embodiment, even if heat is transferred from the battery module 10( Figure 1 ) to the first heat dissipation member 151 and the second heat dissipation member 155, respectively, the central thermal insulation member 170 is capable of blocking heat transfer between the first heat dissipation member 151 and the second heat dissipation member 155.
[0073] Referring to Figure 2 , Figure 3 and Figure 5 (c), the heat dissipation member 150 can include the first heat dissipation member 151 and the second heat dissipation member 155. More specifically, the first heat dissipation member 151 can be located between the inner surface of the first frame 111 and the central thermal insulation member 170, and the second heat dissipation member 155 can be located between the inner surface of the second frame 115 and the central thermal insulation member 170.
[0074] Here, the heat dissipation member 150 can further include a surface curved in a direction perpendicular to the frame member 110. More specifically, the first heat dissipation member 151 can further include a surface curved in a direction perpendicular to the first frame 111, and the second heat dissipation member 155 can further include a surface curved in a direction perpendicular to the second frame 115. Here, the first heat dissipation member 151 and the second heat dissipation member 155 can be curved in opposite directions to each other.
[0075] In addition, the heat dissipation member 150 can be made of a material such as aluminum (Al) or graphite. However, the material of the heat dissipation member 150 is not limited thereto, and can include any material having high thermal conductivity in the present embodiment.
[0076] Thereby, according to the present embodiment, the upper portion of the battery module 10( Figure 1 ) is located near the curved surface of the first heat dissipation member 151 or the curved surface of the second heat dissipation member 155, respectively, so that heat generated in the battery module 10( Figure 1 ) is capable of being easily dissipated to the first heat dissipation member 151 or the second heat dissipation member 155. In addition, the curved surface of the first heat dissipation member 151 or the curved surface of the second heat dissipation member 155 is in contact with a cooling member formed on the upper portion of a battery pack frame (not shown), so that heat generated in the battery module 10( Figure 1 ) is capable of being effectively dissipated.
[0077] Next, the assembly process of each component of the heat dissipation assembly 100 according to this embodiment will be described in detail.
[0078] Figures 6 to 12 This shows the assembly. Figure 1 A diagram illustrating the process of heat dissipation components.
[0079] See Figure 6 ,like Figure 6 As shown in (a), the first insulating member 131 can be located in the groove 210 formed in the pre-prepared clamp 220, and as Figure 6 As shown in (b), the first thermal insulation member 131 can be stably fixed to the groove 210.
[0080] Next, refer to Figure 7 Adjust the position so that the outer surfaces of the first thermal insulation member 131 and the first frame 111 face each other, such as... Figure 7 As shown in (a), the outer surface of the first frame 111 can then be mounted on the first insulation member 131, as... Figure 7 As shown in (b).
[0081] Next, refer to Figure 8 One surface of the first heat dissipation member 151 is located on the inner surface of the first frame 111, wherein a protrusion 113 formed in the first frame 111 can pass through the first heat dissipation member 151. Here, the first heat dissipation member 151 may have a hole whose size corresponds to the size of the pre-formed protrusion 113.
[0082] Next, refer to Figure 9 The central heat insulation member 170 is placed on the first heat dissipation member 151, wherein the protrusion 113 formed in the first frame 111 can pass through the central heat insulation member 170. Here, even in the case of the central heat insulation member 170, a hole with a size corresponding to the size of the protrusion 113 can be pre-formed.
[0083] Next, refer to Figure 10 The second heat dissipation member 155 is placed on the central heat insulation member 170, wherein the protrusion 113 formed on the first frame 111 can pass through the second heat dissipation member 155. Here, even in the case of the second heat dissipation member 155, a hole with a size corresponding to the size of the protrusion 113 can be pre-formed.
[0084] Next, refer to Figure 11 The second frame 115 is folded in a direction in which the inner surface of the second frame 115 and the inner surface of the first frame 111 face each other, wherein the inner surface of the second frame 115 can be placed on the second heat dissipation member 155.
[0085] Next, refer to Figure 12The second heat insulating member 135 can be disposed on the outer surface of the second frame 115.
[0086] Accordingly, according to the present embodiment, the heat dissipation assembly 100 can have respective components assembled through the above-described process, whereby the assembly process is relatively simple and can be fixed through mechanical coupling between the components without a separate adhesive layer, thereby further improving productivity.
[0087] Further, although not shown in Figures 6 to 12 , according to another embodiment of the present disclosure, a hook structure or a snap-fit structure is formed on at least a portion of the components, whereby the components included in the heat dissipation assembly 100 can be fixed to each other through hook coupling or snap-fit coupling.
[0088] Accordingly, according to the present embodiment, the coupling force between the components is further improved, and thus, the quality of the heat dissipation assembly 100 can also be further improved.
[0089] Next, a heat dissipation assembly 100 according to another embodiment of the present disclosure will be described. At this time, the heat dissipation assembly according to the present embodiment includes all configurations of the heat dissipation assembly according to the present embodiment, and the respective descriptions will be omitted to avoid repetition and redundancy.
[0090] Figure 13 and Figure 14 are drawings illustrating a heat dissipation assembly according to another embodiment of the present disclosure.
[0091] Referring to Figure 13 and Figure 14 , the heat dissipation assembly 100 according to the present embodiment can further include a cooling pad 190 formed on the heat dissipation member 150. That is, the heat dissipation assembly 100 according to the present embodiment can further include a cooling pad 190 formed on the first heat dissipation member 151 and the second heat dissipation member 155. More specifically, the cooling pad 190 included in the heat dissipation assembly 100 according to the present embodiment can be formed of a compressible cooling pad.
[0092] The cooling pad 190 can be formed on the curved surfaces of the first heat dissipation member 151 and the second heat dissipation member 155. At this time, the cooling pad 190 can be formed to have the same area as the curved surfaces, or can be formed to have an area smaller than the curved surfaces. Accordingly, heat transferred through the first heat dissipation member 151 and the second heat dissipation member 152 can be rapidly cooled and transferred through the cooling pad 190.
[0093] In this case, the cooling pad 190 can be formed of a silicon-based or an acrylic-based material. Specifically, the cooling pad 190 can be a silicone pad, a silicone rubber pad, a silicone polymer pad, etc., and can be an acrylic pad, an acrylic polymer pad, etc., but is not limited thereto.
[0094] The cooling pad 190 is formed on the heat dissipation member 150 of the heat dissipation assembly 100 according to the present embodiment, thereby being able to further contact a battery pack frame (not shown) of a battery pack including the heat dissipation assembly 100. Accordingly, heat generated in the battery module 10 is transferred to the battery pack frame of the battery pack through the heat dissipation member 150 and the cooling pad 190, so that the heat generated in the battery module 10 can be effectively and rapidly dissipated. In particular, the cooling pad 190 is formed of a compressible cooling pad and is in close contact with the battery pack frame of the battery pack, thereby minimizing a contact thermal resistance and being able to form an effective heat transfer path.
[0095] Meanwhile, the device according to the present embodiment can include the above-described battery pack. Such a device can be applied to a vehicle device such as an electric bicycle, an electric vehicle, or a hybrid vehicle, but the present disclosure is not limited thereto, and can be applied to various devices that can use a battery module and a battery pack including the battery module, which also falls within the scope of the present disclosure.
