The embodiments of the present application do not limit the setting mode of the cooling pipe.

[0072] Next, the specific structure of the heat dissipation device 100 provided in the embodiments of the present application will be described.

[0073] Figure 3 A structure diagram of a heat dissipation device provided in the embodiments of the present application is provided; Figure 4 Another structure diagram of a heat dissipation device provided in the embodiments of the present application is provided; Figure 5 An explosion diagram of a heat dissipation device provided in the embodiments of the present application is provided.

[0074] Referring to Figures 3 to 5 As shown in the drawings, the heat dissipation device 100 provided by the embodiments of the present application comprises a support structure 110, a heat exchanger 150, a liquid storage tank 120, a pump body 130 and a first adapter pipe 141. The heat exchanger 150 is arranged in the support structure 110, the liquid storage tank 120 is arranged on the support structure 110, the liquid storage tank 120 is in communication with the heat exchanger 150, and the liquid storage tank 120 comprises a liquid storage tank outlet 121. The pump body 130 is also arranged on the support structure 110, and the pump body 130 comprises a pump body inlet 131, which is oriented in a first direction X. The first adapter pipe 141 extends along the first direction X, one end of the first adapter pipe 141 is in communication with the liquid storage tank outlet 121, and the other end of the first adapter pipe 141 is aligned with and in communication with the pump body inlet 131.

[0075] Exemplarily, the support structure 110 can be a cuboid structure, and the support structure 110 has a first direction X, a second direction Y and a third direction Z. The support structure 110 comprises a base plate 114 and a side wall connected in sequence around the side of the base plate 114, and the side wall is respectively a first side wall 111, a second side wall 112 and a third side wall 113. The first side wall 111 and the third side wall 113 are oppositely arranged along the third direction Z, and the side opposite to the second side wall 112 along the first direction X is an open structure. The base plate 114 and the side wall form a containing cavity, and the heat exchanger 150 is located in the containing cavity.

[0076] The heat exchanger 150 comprises a heat exchanger inlet 151, a heat exchange element 152 and a heat exchanger outlet 153 connected in sequence. In Figures 3 to 5 Two heat exchanger inlets 151 are shown in the drawings. The heat exchange element 152 can be one whole body or a plurality of heat exchange fins, and the plurality of heat exchange fins are arranged in a stack along the third direction Z in the containing cavity.

[0077] Figure 6 For Figure 5 An enlarged view of position A in the drawings.

[0078] Referring to Figure 6 As shown in the drawings, the heat exchange element 152 comprises a heat exchange element body 1521, a circulating channel 1522 in the heat exchange element body 1521, and a heat dissipation fin 1523 attached to the side surface of the heat exchange element body 1521, and the heat dissipation fin 1523 forms a heat dissipation channel. Figure 6 In the embodiment shown in the drawings, the heat dissipation fin 1523 is bent to form the heat dissipation channel. Please continue to refer to Figure 3 and Figure 5 The heat dissipation device 100 further comprises a fan 154, which can be installed on the base plate 114. A first temperature sensor 155 is also arranged near the heat exchanger inlet 151, and the first temperature sensor 155 is used to detect the temperature of the cooling liquid before entering the heat exchanger 150.

[0079] The heat dissipation device 100 further comprises a liquid storage tank 120 for storing the cooling liquid, the liquid storage tank 120 comprises a liquid storage tank inlet 122 and a liquid storage tank outlet 121, and the liquid storage tank 120 is further provided with a liquid level gauge 123 for detecting the liquid level in the liquid storage tank 120. The liquid storage tank 120 is further provided with a second temperature sensor 124 for detecting the temperature of the cooling liquid in the liquid storage tank 120.

[0080] The heat dissipation device 100 further comprises a pump body 130 for providing power for circulating the cooling liquid. The pump body 130 comprises a pump body inlet 131 and a pump body outlet 132, the liquid outlet flow channel 420 of the cooling pipe 400 is communicated with the heat exchanger inlet 151, the heat exchanger outlet 153 is communicated with the liquid storage tank inlet 122 through the second adapter pipe 142, the liquid storage tank outlet 121 is communicated with the pump body inlet 131 through the first adapter pipe 141, and the pump body outlet 132 is communicated with the liquid inlet flow channel 410 of the cooling pipe 400 through the third adapter pipe 143. In this way, the liquid outlet flow channel 420 of the cooling pipe 400, the heat exchanger 150, the liquid storage tank 120, the pump body 130 and the liquid inlet flow channel 410 of the cooling pipe 400 are sequentially communicated.

[0081] The cooling liquid in the liquid outlet flow channel 420, which absorbs heat, flows into the circulation channel 1522 of the heat exchange part 152 from the heat exchanger inlet 151, and the heat is transferred from the circulation channel 1522 to the heat dissipation fins 1523. When the fan 154 is turned on, the fan 154 can blow or suck air, and the fan 154 can form an air flow when blowing or sucking air, which can carry away the heat of the heat dissipation fins 1523, thereby cooling the cooling liquid in the circulation channel 1522. The cooled cooling liquid flows out of the heat exchanger outlet 153 and enters the liquid storage tank 120, and is pumped by the pump body 130 and enters the liquid inlet flow channel 410 of the cooling pipe 400 through the third adapter pipe 143, and thus circulates to dissipate heat for the cable 220.

[0082] The pump body 130 can be a gear pump, a piston pump, a plunger pump, a gear pump, a screw pump, a vane pump, etc. In the case that the length of the cable 220 is relatively long and the diameter of the cable 220 is relatively small, the length of the cooling pipe 400 is also relatively long, and it is difficult to set the diameter of the cooling pipe 400 to be relatively large. The required driving force for the cooling liquid to flow in the cooling pipe 400 is large, and the pressure drop of the cooling liquid is large. The gear pump has the advantages of small flow and high lift, and the gear pump can provide a large driving force for the cooling liquid in the cooling pipe 400.

[0083] Next, the structure of the pump body 130 will be described taking the gear pump as an example.

[0084] Figure 7 The structure of the pump body in the heat dissipation device provided by the embodiment of the present application is shown in the schematic diagram.

[0085] See Figure 7 As shown, the pump body 130 includes a pump casing 133, a pump inlet 131 and a pump outlet 132 are located on opposite sides of the pump casing 133, and two gears 134 of the same specifications but rotating in opposite directions are provided in the pump casing 133, each gear having multiple teeth 1341. On the pump inlet 131 side, the two gears 134 respectively rotate along... Figure 7 As the gear rotates in the direction indicated by the middle arrow, a sealed space is formed between the multiple teeth 1341 of the gear 134 and the pump housing 133. With the rotation of the gear, a low pressure is created on the pump inlet 131 side, drawing coolant in. The coolant flows along the space between the two gears 134 and the pump housing 133 to the pump outlet 132 side, where a high pressure is created, causing the coolant to flow out. Pressure sensors can be installed at both the pump inlet 131 and the pump outlet 132 to detect the pressure at each location. The low and high pressures at the pump inlet and outlet 132 provide the driving force for coolant flow. Due to the low pressure at the pump inlet, a large number of bubbles are generated in the coolant. These bubbles impact the gears and pump housing, producing noise and resulting in relatively high noise levels during operation of the cooling system.

[0086] In this embodiment, the pump inlet 131 can be oriented in the first direction X, and the first adapter pipe 141 can also extend along the first direction X. The end of the first adapter pipe 141 facing the pump inlet 131 is aligned with the pump inlet 131 along the first direction X. The end of the first adapter pipe 141 facing the reservoir outlet 121 is connected to the reservoir outlet 121. Therefore, when connecting the reservoir outlet 121 and the pump inlet 131, the first adapter pipe 141 can connect to the pump inlet 131 without bending. When the coolant flows from the first adapter pipe 141 into the pump inlet 131, the coolant also flows along the first direction X. The flow direction of the coolant does not change, and the pressure of the coolant does not decrease due to the change in flow direction. This avoids further reducing the pressure at the pump inlet 131, thereby reducing the amount of air bubbles in the coolant and reducing the noise during operation of the heat dissipation device 100.

[0087] In one possible implementation, the diameter of the first adapter pipe 141 is greater than or equal to about 9 mm.

[0088] Figure 8 An exploded view of the connection between the first adapter pipe and the pump body in the heat dissipation device provided in the embodiments of this application.

[0089] See Figure 8As shown, at the connection between the first adapter pipe 141 and the pump body inlet 131, the first adapter pipe 141 is connected with the pump body inlet 131 through a connection joint 1411, which can be a lotus-shaped joint. The connection joint 1411 has a threaded joint 1411a on the side facing the pump body inlet 131. The pump body inlet 131 has an internal thread, and the threaded joint 1411a of the connection joint 1411 can be threadedly connected with the internal thread of the pump body inlet 131. The connection joint 1411 has a lotus head 1411b on the side facing the connection joint 1411. The lotus head 1411b is inserted into the first adapter pipe 141. The first adapter pipe 141 has a clamping member 1412 outside the first adapter pipe 141 to connect the lotus head 1411b and the first adapter pipe 141.

[0090] The flow rate of the cooling liquid required for heat dissipation of the charging gun 200 is set according to the power of the charging gun 200, and thus the flow rate of the cooling liquid is set. When the pipe diameter of the first adapter pipe 141 is set to be small, the flow rate of the cooling liquid in the circuit is large, and air bubbles are more likely to be generated in the low-pressure environment of the pump body inlet 131, which can increase the noise of the operation of the heat dissipation device 100. Therefore, in the embodiment of the present application, the pipe diameter of the first adapter pipe 141 can be greater than or equal to about 9 mm to reduce the flow rate of the cooling liquid. For example, when the flow rate of the cooling liquid is less than 4.5 L / min, the flow rate at the pump body inlet 131 can be less than 0.5 m / s.

[0091] It should be noted that the diameter of the lotus head 1411b inserted into the first adapter pipe 141 matches the pipe diameter of the first adapter pipe 141. The diameter of the lotus head 1411b can be about 7 mm, and the diameter of the threaded joint 1411a can be about 10 mm.

[0093] Referring to Figure 3 and Figure 9 As shown, the heat dissipation device 100 further includes a first adapter 160 having opposite first and second ends 160a and 160b. The first end 160a is connected with the first side wall 111 of the support structure 110, and the second end 160b has a plurality of first connecting portions 161 arranged in the second direction Y. The pump body 130 has a plurality of second connecting portions 135 arranged in the second direction Y. The pump body inlet 131 is aligned with the liquid tank outlet 121 in the first direction X. At least part of the first connecting portions 161 are connected with at least part of the second connecting portions 135.

[0094] The axial direction L of the pump shell 133 is consistent with the second direction Y of the support structure 110.

In another possible implementation, the adapter body 162 is a connecting rod, the mounting portion 163 is connected with the adapter body 162, the projection area of the mounting portion 163 on the first side wall 111 is larger than the projection area of the adapter body 162 on the first side wall 111, and the mounting portion 163 is attached to the first side wall 111, so that the contact area of the mounting portion 163 with the first side wall 111 is large, and the connection between the mounting portion 163 and the first side wall 111 is more reliable.

[0103] The second reinforcing part 172 is attached to and connected with the second side wall 112, and the first reinforcing part 171 is bent from the second reinforcing part 172 towards the first side wall 111 at the connection between the second side wall 112 and the first side wall 111. The first reinforcing part 171 is attached to and connected with the first side wall 111. The first adapter 160 is connected with the first reinforcing part 171 to be connected with the first side wall 111 through the first reinforcing part 171. By arranging the first reinforcing part 171, the strength of the first side wall 111 at the connection with the pump body 130 can be increased, and the deformation of the first side wall 111 caused by the vibration of the pump body 130 can be reduced. By arranging the second reinforcing part 172 connected with the first reinforcing part 171 and connecting the second reinforcing part 172 with the second side wall 112, the reliability of the connection between the first reinforcing part 170 and the support structure 110 can be increased. Thus, the noise caused by the vibration during the operation of the heat dissipation device 100 can be further reduced.

[0104] Please continue to refer to Figure 10 and Figure 11 As shown in

[0105] The third reinforcing part 173 is connected with the third side wall 113 after being bent from the second reinforcing part 172 towards the third side wall 113 at the connection between the second side wall 112 and the third side wall 113. The third reinforcing part 173 can be connected with the third side wall 113 through fasteners. Thus, the first reinforcing part 170 reinforces the support structure 110 from three side walls, so that the support structure 110 has high strength and compact structure, and the noise caused by the vibration during the operation of the heat dissipation device 100 can be further reduced.

[0106] Please continue to refer to Figure 10 and Figure 11 As shown in

[0107] The reinforcing part body 1711 has a first face 1711a facing the first side wall 111 and a second face 1711b away from the first side wall 111.

By providing the second reinforcing member 180 and connecting the first reinforcing portion 171 and the second reinforcing portion 172 through the second reinforcing member 180, the tendency of the first reinforcing portion 171 and the second reinforcing portion 172 to move away from each other can be reduced, so that the structural reliability of the heat dissipation device 100 is higher.
