When the battery module temperature is high and heat dissipation is required, the battery heat dissipation and insulation system is in a heat dissipation state. At this time, the shielding member can expose the heat dissipation vent, and the battery module can dissipate heat through the heat dissipation channel of the heat dissipation member. When the battery module temperature is low and heat preservation is required, the battery heat dissipation and insulation system is in a heat preservation state. At this time, the shielding member can block the heat dissipation vent, thereby reducing heat loss caused by the battery module through the heat dissipation channel and thus preserving the battery module.

[0030] Figure 1 This is a schematic diagram of a battery heat dissipation and insulation system provided in an embodiment of the present disclosure in a heat dissipation state. Figure 2 This is another schematic diagram of the battery heat dissipation and heat preservation system provided in the embodiments of this disclosure in a heat dissipation state. Figure 3 This is a schematic diagram of a battery heat dissipation and heat preservation system in a heat preservation state, as provided in an embodiment of this disclosure. Figure 4 This is a schematic diagram of a heat dissipation module and a battery module in a battery heat dissipation and insulation system provided in an embodiment of this disclosure. Figure 5 This is a schematic diagram of the structure of the insulation component, heat dissipation component, and battery module in the battery heat dissipation and insulation system provided in the embodiments of this disclosure.

[0031] refer to Figures 1 to 5 The battery heat dissipation and insulation system includes: a battery module 1, a heat dissipation module 2, and an insulation module 3. The heat dissipation module 2 includes a heat sink 21, which is disposed on one side of the battery module 1. The heat sink 21 has a heat dissipation channel for heat dissipation and heat dissipation vents located on opposite sides of the heat dissipation channel. The insulation module 3 includes a shielding member 31, which is disposed on at least one side of the heat dissipation channel. The shielding member 31 can expose the heat dissipation vents in the heat dissipation state and block the heat dissipation vents in the heat insulation state.

[0032] Figure 6 This is a schematic diagram of a battery module in a battery heat dissipation and insulation system provided in an embodiment of this disclosure.

[0033] refer to Figure 6 In some embodiments, the battery module includes a housing 11 with a receiving cavity and a battery module 12 placed in the receiving cavity. The housing 11 is used to protect the battery module 12, which is the core component of the battery module 1 and is used to provide or store electrical energy.

[0034] The battery module 1 also includes a cover plate 13. The cover plate 13 is located on one side of the battery module 12 and is connected to the housing 11. An adhesive layer (not shown) may be provided between the cover plate 13 and the housing 11, and the cover plate 13 is bonded to the housing 11 by the adhesive layer.

[0035] A connector 14 may be provided on the cover plate 13. The connector 14 is used to connect the battery module 12 to other components. The connector 14 can be fixed to the cover plate 13 by bolts or other fixing components.

[0036] refer to Figure 1 , Figure 4 and Figure 5 The heat dissipation module 2 is used to dissipate heat from the battery module 1. The heat dissipation module 2 includes a heat sink 21, which has heat dissipation vents at both ends. When the heat dissipation vents are exposed, the heat dissipation channel of the heat sink 21 allows air to circulate, so that the heat sink 21 can exchange heat with the air, thereby reducing the temperature of the battery module 1 and dissipating heat from the battery module 1.

[0037] The insulation module 3 is used to insulate the battery module 1. The insulation module 3 includes a shielding member 31, which can block the heat dissipation vents during the insulation process, reducing heat loss from the battery module 1 caused by the heat dissipation component 21, thus achieving the insulation effect. Alternatively, the shielding member 31 can expose the heat dissipation vents during the heat dissipation process, allowing the heat dissipation component 21 to exchange heat with the air, thereby dissipating heat from the battery module 1.

[0038] In some embodiments, the shielding member 31 has a first state and a second state. In the heat dissipation state, the shielding member 31 is in the first state, and the shielding member 31 exposes the heat dissipation vent. In the heat preservation state, the shielding member 31 is in the second state, and the shielding member 31 blocks the heat dissipation vent. In this way, the shielding member 31 can switch between the first state and the second state to expose or block the heat dissipation vent, thereby achieving heat dissipation and heat preservation of the battery module 1.

[0039] In some embodiments, the shielding element 31 is phase change foam.

[0040] Phase change foam is foam filled with phase change material. The volume of the phase change foam changes with temperature, thus switching between a first state and a second state. When the temperature of battery module 1 is high, the phase change foam is in the first state and exposes the heat dissipation vents, allowing the battery module 1 to dissipate heat through the heat sink 21. When the temperature of battery module 1 is low, the phase change foam expands in volume to the second state due to temperature changes and blocks the heat dissipation vents, thereby reducing heat loss from battery module 1 due to the heat sink 21 and thus insulating battery module 1.

[0041] In other embodiments, the shielding member 31 is movable relative to the battery module 1. In a first state, the shielding member 31 is moved away from and exposes the heat dissipation vent, allowing the battery module 1 to dissipate heat through the heat dissipation member 21. In a second state, the shielding member 31 is positioned on and blocks the heat dissipation vent to reduce heat loss from the battery module 1 due to the heat dissipation member 21, thereby insulating the battery module 1.

[0042] In some embodiments, the battery heat dissipation and insulation system includes multiple battery modules 1 arranged along a first direction X. For the same heat sink 21, the direction from one heat sink vent to another is perpendicular to the first direction X. That is, the two heat sink vents are located in the direction perpendicular to the first direction X of the heat sink 21, which facilitates air circulation in the heat dissipation channel, thereby improving the heat exchange efficiency of the heat sink 21.

[0043] Multiple battery modules 1 can be connected via connector 14.

[0044] In some embodiments, the battery heat dissipation and insulation system includes a plurality of battery modules 1 arranged along a first direction X. The heat dissipation outlets include a first heat dissipation outlet 211 and a second heat dissipation outlet 212 located on opposite sides of the heat dissipation channel. The extension direction of the heat dissipation channel is parallel to the first direction X. The shielding member 31 includes a first shielding member 311 disposed near the first heat dissipation outlet 211 and a second shielding member 312 disposed near the second heat dissipation outlet 212.

[0045] In some embodiments, the battery heat dissipation and insulation system includes a plurality of heat dissipation modules 2, each corresponding to a battery module 1. The plurality of heat dissipation modules 2 are stacked along a first direction X. A first heat dissipation vent 211 is formed on one side of each heat dissipation module 2, and a second heat dissipation vent 212 is formed on the opposite side of each heat dissipation module 2. Thus, each battery module 1 is equipped with one heat dissipation module 2 for heat dissipation. The plurality of heat dissipation modules 2 are also stacked along the first direction X. The heat dissipation channels of the plurality of heat dissipation modules 2 can be interconnected, allowing air to circulate within the heat dissipation channels of the stacked heat dissipation modules 2.

[0046] In other embodiments, the battery heat dissipation and insulation system includes an integrally formed heat dissipation module 2, which is used to dissipate heat from multiple battery modules 1.

[0047] Figure 7 This is a schematic diagram of a support base and a first shielding member in a battery heat dissipation and insulation system provided in an embodiment of this disclosure.

[0048] refer to Figure 1 and Figure 7 In some embodiments, the battery heat dissipation and insulation system further includes: a support base 4, which is located on one side of the battery module 1, and a first shielding member 311 is located on the support base 4.

[0049] The support base 4 is used to support the battery module 1, which can prevent the battery module 1 from directly contacting objects and causing damage to the battery module 1. The first shielding member 311 is located on the support base 4 to expose or shield the first heat dissipation vent 211.

[0050] In some embodiments, an adhesive layer (not shown) is provided between the first shielding member 311 and the support base 4, and the first shielding member 311 is bonded to the support base 4 through the adhesive layer.

[0051] Figure 8 This is a schematic diagram of a control box and a second shielding component in a battery heat dissipation and insulation system provided in an embodiment of this disclosure.

[0052] refer to Figure 1 and Figure 8 In some embodiments, the battery heat dissipation and insulation system further includes: a control box 5, which is located on the opposite side of the battery module 1 and is electrically connected to the battery module 1, and a second shield 312 is located on the control box 5.

[0053] The control box 5 can be connected to the battery module 1 for real-time monitoring, safety protection, equalization management, and data communication, ensuring the safe, efficient, and stable operation of the battery module 1.

[0054] The second shielding member 312 is located on the control box 5 to expose or block the second heat dissipation vent 212. In some embodiments, an adhesive layer (not shown) is provided between the second shielding member 312 and the control box 5, and the second shielding member 312 is bonded to the control box 5 by the adhesive layer.

[0055] Continue to refer to Figures 1 to 5 In some embodiments, the heat sink 21 includes a main body 213 and a plurality of heat dissipation teeth 214 spaced apart within the main body 213. The heat dissipation module 2 also includes a heat-conducting plate 22, which is located between the battery module 1 and the heat sink 21. In the heat dissipation state, the first shielding member 311 and the second shielding member 312 are in a first state, and the first heat dissipation port 211 and the second heat dissipation port 212 are exposed. The heat-conducting plate 22 transfers the heat generated by the battery module 1 to the heat dissipation teeth 214, and exchanges heat with the air through the heat dissipation teeth 214.

[0056] The presence of heat dissipation fins 214 can increase the heat exchange area between the heat sink 21 and the air, thereby improving the heat exchange efficiency of the heat sink 21.

[0057] Both the heat sink 21 and the heat conduction plate 22 can be made of materials with high thermal conductivity. In this way, the heat conduction plate 22 can transfer the heat generated by the battery module 1 to the heat dissipation teeth 214 of the heat sink 21, so that the heat dissipation teeth 214 can exchange heat with the air, thereby dissipating heat from the battery module 1.

[0058] In some embodiments, the heat sink 21 may be made of thermally conductive silicone; the heat-conducting plate 22 may also be made of thermally conductive silicone.

[0059] In some embodiments, the heat preservation module 3 further includes a heat preservation member 32, which covers the outer surface of the main body 213. In the heat preservation state, the first shielding member 311 and the second shielding member 312 are both in the second state. The first heat dissipation port 211 is shielded by the first shielding member 311, and the second heat dissipation port 212 is shielded by the second shielding member 312. The first shielding member 311, the second shielding member 312 and the heat preservation member 32 form a heat preservation layer surrounding the battery module 1.

[0060] The materials of the first shielding member 311, the second shielding member 312, and the heat insulation member 32 can all be low thermal conductivity materials. In this way, under heat insulation conditions, the heat insulation layer formed by the first shielding member 311, the second shielding member 312, and the heat insulation member 32 can play a good heat insulation role.

[0061] In a specific example, insulation component 32 can be a polyurethane board.

[0062] In some embodiments, the insulation module 3 includes a plurality of insulation elements 32, each insulation element 32 being disposed corresponding to a heat dissipation element 21. In other embodiments, the insulation module 3 includes a single insulation element 32, which is disposed corresponding to a plurality of heat dissipation elements 21, i.e., the insulation element 32 is located on the outer surface of the plurality of heat dissipation elements 21.

[0063] In the battery heat dissipation and insulation system provided above, when the battery module 12 is in a high-temperature environment and its temperature is high, the battery heat dissipation and insulation system is in a heat dissipation state. The heat-conducting plate 22, which has a high thermal conductivity, can transfer the heat generated by the battery module 12 to the heat dissipation teeth 214. The heat is then exchanged with the air through the heat dissipation teeth 214, achieving the purpose of cooling the battery module 12. At this time, both the first shielding member 311 and the second shielding member 312 are in the first state, and the heat dissipation vents of the heat dissipation member 21 are not closed, allowing hot and cold air to circulate in the heat dissipation channel. In addition, when the battery module 12 is in a high-temperature environment or a normal-temperature environment, both the first shielding member 311 and the second shielding member 312 can be in the first state, that is, the first heat dissipation vents 211 and 212 are exposed, allowing air to circulate in the heat dissipation channel for heat exchange.

[0064] When the battery module 12 is in a low-temperature environment, the battery heat dissipation and heat preservation system is in a heat preservation state. The first shielding member 311 and the second shielding member 312 can expand to a second state due to temperature, and shield the first heat dissipation port 211 and the second heat dissipation port 212. In this way, the first shielding member 311 and the second shielding member 312 can form a heat preservation layer with the heat preservation member 32 to prevent cold air from exchanging heat with the battery module 12 and losing the heat of the battery module 12. That is, the battery module 12 is kept warm. This can also prevent the temperature of the side of the battery module 12 close to the heat dissipation tooth 214 from being too low, and avoid the temperature difference between the side and the side away from the heat dissipation tooth 214 from being too large, which would affect the performance of the battery module 12.

[0065] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of this disclosure. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure should be determined by the scope defined in the claims.
