The first heat dissipation body 10 and the second heat dissipation body 20 are used for heat exchange with the charging socket wire harness 2.

[0031] It should be noted that in the related art, an electric vehicle charges the battery through a charging gun and a charging socket. The internal terminals of the charging socket generate heat and the temperature rises. If the charging current is increased, the temperature rise of the existing internal terminals of the charging socket may exceed the allowable temperature rise, causing a safety hazard.

[0032] Based on this, an embodiment of the present application provides a heat dissipation device 1. The heat dissipation device 1 may include a first heat dissipation body 10 and a second heat dissipation body 20. Both the first heat dissipation body 10 and the second heat dissipation body 20 may be made of a high thermal conductivity metal material or a plastic material, so that the first heat dissipation body 10 and the second heat dissipation body 20 have good thermal conductivity. The first heat dissipation body 10 and the second heat dissipation body 20 are disposed opposite to each other and fixedly connected. The first heat dissipation body 10 and the second heat dissipation body 20 can be fixedly connected by means of snap connection, bolt connection, etc. The first heat dissipation body 10 and the second heat dissipation body 20 are assembled in cooperation to jointly define an assembly hole 30 for assembling the charging socket wire harness 2. The assembly hole 30 penetrates the heat dissipation device 1 along the first direction of the heat dissipation device 1. When the heat dissipation device 1 is arranged in the Figure 1 direction, the first direction of the heat dissipation device 1 is Figure 1 the X direction in

[0033] The charging socket wire harness 2 can be passed through the assembly hole 30, and the inner wall of the assembly hole 30 abuts against the charging socket wire harness 2. When the charging socket is charging, the heat generated by the internal terminals of the charging socket can be conducted to the first heat dissipation body 10 and the second heat dissipation body 20 through the charging socket wire harness 2. The first heat dissipation body 10 and the second heat dissipation body 20 can exchange heat with the charging socket wire harness 2, and the heat is dissipated through the first heat dissipation body 10 and the second heat dissipation body 20, so that the temperature of the charging socket wire harness 2 is reduced, thereby reducing the temperature rise of the charging socket terminals during charging and improving the safety of the charging socket.

[0034] In some embodiments of the present utility model, as Figures 2 - 5 shown, a first groove 11 is formed on the side of the first heat dissipation body 10 facing the second heat dissipation body 20, and a second groove 21 is formed on the side of the second heat dissipation body 20 facing the first heat dissipation body 10. When the first heat dissipation body 10 and the second heat dissipation body 20 are connected, the first groove 11 and the second groove 21 are opposite to each other to define the assembly hole 30.

[0035] The first heat sink 10 and the second heat sink 20 are arranged opposite to each other. The first heat sink 10 and the second heat sink 20 jointly define an assembly hole 30 for assembling the charging socket wire harness 2. A first groove 11 is formed on the side of the first heat sink 10 facing the second heat sink 20, and the first groove 11 can avoid the charging socket wire harness 2. A second groove 21 is formed on the side of the second heat sink 20 facing the first heat sink 10, and the second groove 21 can avoid the charging socket wire harness 2.

The inner wall of the first groove 11 can be in close contact with the charging socket wire harness 2, and the inner wall of the second groove 21 can be in close contact with the charging socket wire harness 2, that is, the inner wall of the assembly hole 30 can be in close contact with the outer wall of the charging socket wire harness 2, so that the contact area between the heat dissipation device 1 and the charging socket wire harness 2 can be increased, the heat exchange efficiency between the heat dissipation device 1 and the charging socket wire harness 2 can be improved, and the temperature reduction efficiency of the heat dissipation device 1 for the charging socket can be improved.

[0036] In some embodiments of the present invention, as Figure 1 shown, at least one of the outer surface of the first heat sink 10 and the outer surface of the second heat sink 20 is provided with a heat dissipation structure 40.

A first heat dissipation structure 41 is provided on the outer surface of the first heat sink 10, and a second heat dissipation structure 42 is provided on the outer surface of the second heat sink 20. The heat dissipation structure 40 is in contact with air, and heat convection can be formed between the air and the heat dissipation structure 40, so that the temperature of the heat dissipation structure 40 is reduced. The first heat dissipation structure 41 can form heat convection with the air to reduce the temperature of the first heat sink 10, and the second heat dissipation structure 42 can form heat convection with the air to reduce the temperature of the second heat sink 20. The cooled first heat sink 10 and second heat sink 20 can continue to exchange heat with the charging socket wire harness 2, so as to achieve the effect of continuously reducing the temperature of the charging socket by the heat dissipation device 1.

The plurality of assembly holes 30 that are parallel to each other and spaced apart can space apart the plurality of charging socket wire harnesses 2, reducing the probability of mutual influence when the plurality of charging socket wire harnesses 2 exchange heat with the heat dissipation device 1, which is beneficial to improving the heat dissipation efficiency of the charging socket wire harnesses 2. And the parallel assembly holes 30 facilitate the management and fixation of the charging socket wire harnesses 2, preventing the charging socket wire harnesses 2 from being damaged during the heat dissipation process and extending the service life of the charging socket.

As an example, the fastener can be configured as a bolt, a connecting pin, etc. The fastener can be fixedly connected to the first assembly portion 12 and the second assembly portion 22 respectively, so as to realize the fixed connection between the first heat dissipation body 10 and the second heat dissipation body 20. When the fastener locks the first assembly portion 12 and the second assembly portion 22, the first heat dissipation body 10 and the second heat dissipation body 20 are fixed.
