At the same time, with the continuous improvement of the miniaturization and integration of electronic products, the heat dissipation capacity and mode are increasingly valued, which has become a major bottleneck restricting the intelligent development of new energy vehicle electronic products.

[0045] Referring to Figures 1a-3b According to one embodiment of the present application, a heat dissipation fin is provided, which includes a first connecting end 1211, a free end 1212 and a second connecting end 1213 arranged in sequence along a first direction, the first connecting end 1211 and the second connecting end 1213 are configured to be connected with a fixing member, the free end 1212 is arranged away from the first connecting end 1211 and / or the second connecting end 1213 along a second direction, and the first direction and the second direction have an included angle.

[0046] The heat dissipation fin 12 provided by the embodiment of the present application has a first connecting end 1211, a free end 1212 and a second connecting end 1213, and the first connecting end 1211, the free end 1212 and the second connecting end 1213 are arranged at intervals in the first direction; wherein the first connecting end 1211 and the second connecting end 1213 are both connected with the fixing member, which can stably install the heat dissipation fin 12 on the fixing member. And the free end 1212 is arranged away from the first connecting end 1211 and / or the second connecting end 1213 along the second direction, which is conducive to increasing the heat dissipation area of the heat dissipation fin 12, so that the heat dissipation fin has better heat dissipation effect.

[0047] Referring to Figure 1b , Figure 1c As shown in the figure, in one embodiment, the heat dissipation fin includes a heat dissipation fin 1210, the heat dissipation fin 1210 is communicated with the inside of the fixing member along the first direction, and the heat dissipation fin 1210 is arranged to extend along the second direction; a plurality of heat dissipation fins are arranged, and the first connecting end 1211 of one of the two adjacent heat dissipation fins and the second connecting end 1213 of the other are connected.

[0048] In this specific example, the arrangement of the heat dissipation fin 1210 helps to increase the heat dissipation area of the heat dissipation fin 12 and improve the heat dissipation effect. At the same time, a plurality of heat dissipation fins 12 are arranged, and the first connecting end 1211 of one of the two adjacent heat dissipation fins 12 and the second connecting end 1213 of the other are connected, so that the heat dissipation fin 12 extends to form a wavy shape. When the heat dissipation fin 12 exchanges heat with the external cold air flow, the undulating and extending heat dissipation fin 12 not only has a large contact area with the cold air flow, but also can produce good disturbance effect on the cold air flow, so that the heat dissipation fin 12 has high heat exchange capacity.

[0049] Referring to Figure 1c As shown in the figure, in one embodiment, the heat dissipation fins 1210 are provided in plurality, the plurality of heat dissipation fins 1210 are arranged at intervals, and adjacent two heat dissipation fins 1210 are provided with a gap part 1200 along the first direction.

[0050] In this specific example, the heat dissipation fin 12 contains a plurality of heat dissipation fins 1210 arranged at intervals, so that the heat dissipation fin 12 forms a structure similar to a louver, each heat dissipation fin 1210 can form sufficient contact with the cold air flow, each heat dissipation fin 1210 can generate disturbance to the air flow, thereby ensuring that the heat dissipation fin 12 has high heat exchange capacity.

[0051] Referring to Figure 1a , Figure 1b As shown in the figure, in one embodiment, the heat dissipation fin further comprises a heat dissipation channel 110 configured to be formed between the heat dissipation fin and the fixing part, the heat dissipation channel 110 is provided through along the third direction b, and the heat dissipation channel 110 is adapted to pass through the air flow.

[0052] In this specific example, the arrangement of the heat dissipation channel 110 can make the air flow smoothly between the heat dissipation fin 12 and the fixing part, further improving the heat dissipation effect.

[0053] Referring to Figure 3a As shown in the figure, in one specific example, the first direction is the X direction in Figure 3a , the second direction is the Z direction in Figure 3a , and the third direction is the Y direction in Figure 3a ; that is, the predetermined included angle formed between the first direction, the second direction and the third direction can be 90°.

[0054] According to another embodiment of the present application, referring to Figure 2a As shown in the figure, a heat dissipation assembly is provided, comprising a heat dissipation support 13 and a heat dissipation fin 12 as described above, the heat dissipation support 13 is arranged between the first connecting end 1211 and the second connecting end 1213 along the first direction, and the heat dissipation support 13 is arranged between the free end 1212 and the fixing part along the second direction.

[0055] In the heat dissipation assembly provided in the embodiment of the present application, the heat dissipation support 13 abuts against the heat dissipation fin 12, the heat dissipation support 13 can provide good support to the heat dissipation fin 12, thereby enhancing the strength of the heat dissipation fin 12 and preventing it from deforming or being damaged; and when the heat dissipation fin 12 exchanges heat with the external cold air flow, the heat dissipation support 13 can also form a certain disturbance to the cold air flow, thereby enhancing the heat exchange capacity of the heat dissipation assembly.

[0056] Referring toFigure 2a As shown in the figure, in one embodiment, the heat dissipation supports 13 are provided in plurality, and the heat dissipation supports 13 are provided in correspondence with the heat dissipation fins 12.

[0057] In this specific example, one heat dissipation support 13 is provided between every two adjacent heat dissipation fins 12, so that each heat dissipation fin 12 can be effectively supported, and the stability of the entire heat dissipation assembly is improved.

[0058] Referring to Figure 2b As shown in the figure, in one embodiment, the heat dissipation support 13 has a bottom and a top along the second direction, the bottom is away from the free end 1212, i.e. the bottom is close to the first connecting end 1211 and the second connecting end 1213, and the top is close to the free end 1212, and the cross-sectional area of the top is smaller than that of the bottom.

[0059] In this specific example, the bottom of the heat dissipation support 13 connected with the fixing member has a larger cross-sectional area, so that the heat dissipation support 13 can form a stable connection with the fixing member, thereby providing reliable support for the heat dissipation fin 12. And the cross-sectional area of the top of the heat dissipation support 13 is smaller than that of the bottom, so that under the condition that the height of the heat dissipation support 13 is constant, the heat dissipation support 13 can have a larger side area, thereby making the heat dissipation support 13 more fully contact with the cold air flow and having a stronger heat dissipation capacity.

[0060] Referring to Figure 2b As shown in the figure, in one embodiment, the heat dissipation support 13 is in the shape of a rotary body along the second direction; the heat dissipation support 13 comprises a first rotary body 131 and a second rotary body 132, the side wall of the first rotary body 131 is concave with respect to the heat dissipation fin 12, and the side wall of the second rotary body 132 is convex with respect to the heat dissipation fin 12.

[0061] In this specific example, first, the heat dissipation support 13 in the shape of a rotary body can enhance the disturbance to the cold air flow and improve the heat exchange capacity. And the side wall of the heat dissipation support 13 is not linear, but includes a concave arc surface and a convex arc surface; in this way, the side wall of the heat dissipation support 13 has a larger contact area with the cold air flow and has a stronger heat exchange capacity.

[0062] Referring to Figure 2b As shown in the figure, in one embodiment, along the second direction, the first rotary body 131 and the second rotary body 132 are staggered and spaced.

[0063] In the specific example, along the second direction, i.e. the Z direction in FIG. 1, the first rotary body 131 with the concave side wall and the second rotary body 132 with the convex side wall are staggered and spaced, so that the heat dissipation support 13 has a shape similar to a tower; the heat dissipation support 13 has a stronger disturbance effect on the cold air flow and a better heat exchange effect.

[0064] Referring to Figure 3a In one embodiment, as shown in FIG. 1, the heat dissipation assembly is provided with a plurality of heat dissipation assemblies, and the plurality of heat dissipation assemblies are arranged along the third direction, and a gap is arranged between adjacent two heat dissipation assemblies.

[0065] In the specific example, the plurality of heat dissipation assemblies can achieve a stronger heat dissipation effect; and the plurality of heat dissipation assemblies are arranged in a spaced manner along the third direction, so that the cold air flow can flow in the gap formed between adjacent two heat dissipation fins 12, thereby further improving the heat dissipation capacity.

[0066] In addition, the cross section of the heat dissipation channel 110 formed in the heat dissipation assembly is triangular, and the top of the heat dissipation support 13 and the position close to the top are in abutment with the heat dissipation fin 12; each heat dissipation channel 110 is provided with a heat dissipation support 13, that is, the heat dissipation support 13 is arranged one by one with the heat dissipation channel 110, so that the supporting force of the heat dissipation support 13 on the heat dissipation fin 12 is stronger, and the disturbance effect of the heat dissipation support 13 on the cold air flow is more sufficient.

[0067] According to another embodiment of the present application, referring to Figure 3a , Figure 3b As shown in FIG. 1, a heat dissipation unit is provided, which comprises a heat dissipation housing 11 and a heat dissipation assembly as described above, the heat dissipation housing 11 has a first surface 101; the heat dissipation assembly is arranged on the first surface 101.

[0068] In use, the heat dissipation unit provided in the embodiment of the present application, the heat generated by the electronic product is transmitted to the heat dissipation housing 11, and then transmitted to the heat dissipation assembly connected with the heat dissipation housing 11. In the heat dissipation unit, the heat dissipation assembly can be stably installed on the first surface 101 of the heat dissipation housing 11.

[0069] Referring to Figure 3a , Figure 3b In one embodiment, as shown in FIG. 1, the first connecting end 1211 and the second connecting end 1213 are connected with the first surface 101; and the heat dissipation support 13 is connected with the first surface 101.

[0070] In the specific example, the first connecting end 1211 and the second connecting end 1213 of the heat dissipation fin 12 are connected with the first surface 101 of the heat dissipation shell 11, and the heat dissipation support 13 is also connected with the first surface 101; in this way, the heat dissipation assembly can be firmly mounted on the heat dissipation shell 11, and the stability and reliability of the whole heat dissipation unit are improved.

[0071] Referring to Figure 3a , Figure 3b In one embodiment, the heat dissipation shell 11 has a second surface 102 which is arranged opposite to the first surface 101, and the second surface 102 is provided with a plurality of heat dissipation protrusions 15 which are arranged protruding away from the second surface 102.

[0072] In the specific example, by arranging the heat dissipation protrusions 15, the heat emitted by the electronic product is transferred to the heat dissipation shell 11 through the heat dissipation protrusions 15, and then to the heat dissipation assembly for dissipation; in this way, the heat transfer effect is better. The arrangement of the heat dissipation protrusions 15 can increase the heat dissipation area of the heat dissipation shell 11 and improve the heat dissipation effect.

[0073] According to still another embodiment of the present application, referring to Figure 3a , Figure 3b A heat dissipation system 1 is provided, which comprises the heat dissipation unit as described above, and further comprises a cooling member 14 which is configured to provide a cold air flow to the heat dissipation unit.

[0074] In use, the heat dissipation system provided in the embodiments of the present application can transfer the heat emitted by the electronic product to the heat dissipation shell 11, and then to the heat dissipation assembly connected with the heat dissipation shell 11; at the same time, the cold air flow provided by the cooling member 14 blows to the heat dissipation assembly, thereby taking away the heat on the heat dissipation assembly, and achieving the purpose of heat dissipation and cooling for the electronic product.

[0075] In the heat dissipation system 1 provided in the embodiments of the present application, the heat dissipation support 13 is arranged in the heat dissipation channel 110 formed by the heat dissipation fin 12, and the heat dissipation support 13 abuts against the heat dissipation fin 12; therefore, the heat dissipation support 13 can provide good support to the heat dissipation fin 12, thereby enhancing the strength of the heat dissipation fin 12. Moreover, the heat dissipation channel 110 where the heat dissipation support 13 is arranged is in communication with the environment outside the heat dissipation fin 12; therefore, the cold air flow provided by the cooling member 14 can blow to the heat dissipation fin 12 and also contact the heat dissipation support 13, and the heat dissipation support 13 forms a certain disturbance to the cold air flow, thereby enhancing the heat exchange capacity of the heat dissipation system 1 and improving the effect of heat dissipation for the electronic product through the heat dissipation system 1.

[0076] In addition, the gap part 1200 between two adjacent heat dissipation fins 1210 is communicated with the heat dissipation channel 110, so that the cold air flow not only can directly reach the heat dissipation channel 110 and contact the heat dissipation support 13, but also can reach the heat dissipation channel 110 and contact the heat dissipation support 13 via the gap part 1200 between two adjacent heat dissipation fins 1210. In the process of the cold air flow entering and exiting the heat dissipation channel 110 via the above gap, the heat transferred to the heat dissipation fin 12 and the heat dissipation support 13 by the electronic product can be fully taken away.

[0077] Referring to Figure 3a , Figure 3b As shown in the figure, in one embodiment, the cooling supply part 14 includes an air compressor 141 and a vortex tube 142, the air compressor 141 is connected with the air inlet end of the vortex tube 142, and the cold air outlet end of the vortex tube 142 is connected with the heat dissipation unit. Further, a cooling supply pipe 143 is also included, the air inlet end of the cooling supply pipe 143 is connected with the cold air outlet end, the air outlet end of the cooling supply pipe 143 is connected with the heat dissipation shell 11, and the air outlet end of the cooling supply pipe 143 is provided with a plurality of

[0078] In this specific example, the air compressor 141 is connected with the vortex tube 142 through a connecting pipe 144, after the compressed gas provided by the air compressor 141 enters the vortex chamber of the vortex tube 142, the gas flow rotates at high speed and flows to the hot gas outlet end of the vortex tube, a part of the gas flow flows out through the control valve, and the remaining gas is blocked and reversely rotates at the same speed in the inner circle of the original gas flow, and then flows to the cold gas outlet end of the vortex tube. In this process, heat exchange occurs between the two gas flows, the inner ring gas flow becomes very cold, flows out from the cold gas outlet end of the vortex tube and enters the heat dissipation unit via the cooling supply pipe 143; and the outer ring gas flow becomes very hot, flows out from the hot gas outlet end of the vortex tube, and the outflowing hot gas flow can be discharged to the passenger compartment or used for heat preservation of the battery pack. The arrangement of the cooling supply pipe 143 can make the cold air flow uniformly flow to the heat dissipation unit, thereby improving the heat dissipation effect.

[0079] In addition, the vortex tube 142 is used to provide cold air flow for the heat dissipation assembly, on the one hand, the vortex tube can generate cold air flow with very low temperature, so that there is a large temperature difference between the cold air flow and the heat dissipation assembly, and the cooling effect is better. Moreover, the vortex tube does not need electricity and does not need to rely on any chemical substances, which not only can save energy, but also has higher safety.

[0080] In addition, referring to Figure 3a , Figure 3bAs shown, in one embodiment, the cooling pipe 143 comprises a cooling main pipe 1431 and a plurality of cooling branch pipes 1432, the first end of the cooling main pipe 1431 is connected with the vortex pipe 142, one end of each of the cooling branch pipes 1432 is connected with the second end of the cooling main pipe 1431, and the other end of each of the cooling branch pipes 1432 leads to the heat dissipation assembly; that is, each gas outlet end of the cooling pipe 143 corresponds to one cooling branch pipe 1432.

[0081] In this specific example, the cold air flow generated by the vortex pipe 142 first enters the cooling main pipe 1431, and then is distributed to the plurality of cooling branch pipes 1432, and finally flows from the cooling branch pipes 1432 to the heat dissipation assembly, so that the cold air flow can flow more uniformly to the heat dissipation assembly, thereby achieving better heat dissipation effect.

[0082] Referring to ​ , ​ As shown, in one embodiment, the heat dissipation housing 11 comprises a first housing part 111 and a second housing part 112, the second housing part 112 is arranged higher than the first surface 101 of the first housing part 111 in the second direction, the heat dissipation assembly is arranged in the first housing part 111, the second housing part 112 is provided with a gas outlet 100 facing the heat dissipation assembly in the third direction, and the gas outlet end of the cooling pipe 143 communicates with the gas outlet 100 of the second housing part 112; the gas outlet 100 is arranged at the side of the heat dissipation assembly along the third direction.

[0083] In this specific example, the cold air flow flows out of the cooling branch pipe 1432, and then flows to the heat dissipation assembly through the gas outlet 100. Optionally, the gas outlet 100 is arranged one-to-one corresponding to the cooling branch pipe 1432. That is, each cooling branch pipe 1432 is connected with one gas outlet 100, thereby being able to provide the heat dissipation assembly with more uniform cold air flow.

[0084] In one embodiment, the heat dissipation channel 110 is arranged penetratingly in the third direction, and the gas outlet 100 is arranged at the side of the heat dissipation assembly along the third direction.

[0085] In this specific example, the direction opposite to the heat dissipation assembly of the gas outlet 100 is the same as the direction in which the heat dissipation channel 110 penetrates, so that the cold air flow out of the gas outlet 100 can enter the heat dissipation channel 110 and contact the heat dissipation support 13, thereby improving the heat exchange capacity of the heat dissipation system 1.

[0086] In addition, the plurality of gas outlets 100 are arranged in the first direction, that is, the direction in which the plurality of gas outlets 100 are arranged is the same as the direction in which the heat dissipation fins 12 extend in a wave shape, so that along the direction in which the heat dissipation fins 12 extend, the heat dissipation fins 12 and the cold air flow out of the gas outlets 100 can be fully and uniformly exchanged.

[0087] According to still another embodiment of the present application, an electronic device is provided, which comprises the heat dissipation system 1 as described above, and further comprises a heat generating component connected with the heat dissipation housing 11.

[0088] In the electronic device provided by the embodiments of the present application, the heat generated by the heat generating component is transferred to the heat dissipation housing 11, and then transferred to the heat dissipation fins 12 and the heat dissipation support 13 connected with the heat dissipation housing 11; at the same time, the cold air flow provided by the cooling component 14 blows to the heat dissipation fins 12 and the heat dissipation support 13, so as to take away the heat on the heat dissipation fins 12 and the heat dissipation support 13, thereby achieving the purpose of heat dissipation and temperature reduction for the heat generating component.

[0089] In one embodiment, the heat dissipation housing 11 is provided with a plurality of heat dissipation protrusions 15, and the heat generating component is connected with the heat dissipation housing 11 through the heat dissipation protrusions 15; the heat generating component is a controller.

[0090] In this specific example, the heat generated by the heat generating component is transferred to the heat dissipation housing 11 through the heat dissipation protrusions 15, and then transferred to the heat dissipation fins 12 and the heat dissipation support 13 for dissipation; in this way, the heat transfer effect is better.

[0091] In one specific example, the electronic device can be a domain controller, and the heat generating component can be a chip of the domain controller.

[0092] In addition, for the case that the domain controller operates under different heat loads, the cold air flow and temperature generated by the vortex tube 142 can be adjusted by adjusting the rotating speed of the air compressor 141, so as to ensure that there is a large temperature difference between the surfaces of the heat dissipation fins 12 and the heat dissipation support 13 and the cold air flow, thereby ensuring that the domain controller can be sufficiently cooled.

[0093] Specifically, when the domain controller operates under a high-power working condition, the heat generated by the domain controller is large, at this time, the air compressor 141 is controlled to work in a high rotating speed range, so as to ensure that the vortex tube 142 can generate a sufficient amount of cold air flow; when the cold air flow uniformly blows to the heat dissipation fins 12 and the heat dissipation support 13, due to the large temperature difference between the cold air flow and the heat dissipation fins 12 and the heat dissipation support 13, the heat generated by the domain controller is taken away, the temperature of the domain controller is reduced, and the operation life and reliability of the domain controller are enhanced. When the domain controller operates under a medium-power working condition, the air compressor 141 is controlled to work in a normal rotating speed range, at this time, it is only required to ensure that the amount of cold air flow is sufficient. When the domain controller operates under a low-power working condition, the air compressor 141 is controlled to work in a low rotating speed range, while the cooling capacity is ensured, the energy consumption of the air compressor 141 itself is also reduced.

[0094] In summary, by adjusting the rotating speed of the air compressor 141, the cooling requirement of the domain controller in the three operating conditions of small power, medium power and large power can be realized, the cooling requirement of the domain controller in different operating conditions is precisely controlled, the thermal load of the domain controller is reduced, the working reliability is ensured, and the service life is prolonged.
