[0042] Next, a small charging gun cooling device according to an embodiment of the present utility model is described.

[0043] like Figures 1 to 3 As shown, the small charging gun cooling device of the embodiment of the utility model includes a liquid storage tank 110 , a centrifugal pump 200 , a manifold block 310 and a microchannel radiator 410 .

[0044] First, the liquid storage tank 110 and the centrifugal pump 200 are described. The liquid storage tank 110 contains cooling liquid. The centrifugal pump 200 is located below the liquid storage tank 110, and its liquid inlet end is connected to the liquid outlet end of the liquid storage tank 110 to receive the cooling liquid from the liquid storage tank 110.

[0045] like Figure 1 and Figure 2 As shown, the liquid storage tank 110 contains coolant, and the liquid inlet end of the centrifugal pump 200 draws coolant from the liquid storage tank 110 and delivers the coolant to the liquid outlet end of the centrifugal pump 200 .

[0046] Next, the manifold block 310, the first quick connector 321, and the second quick connector 322 are described. The manifold block 310 is disposed on the side of the liquid storage tank 110, and the manifold block 310 has a first channel and a second channel spaced apart therefrom. The liquid outlet of the centrifugal pump 200 is connected to the first channel. The first quick connector 321 is connected to the first channel of the manifold block 310, and the second quick connector 321 is connected to the second channel of the manifold block 310.

[0047] The centrifugal pump 200 pumps the coolant in the liquid storage tank 110 to the first channel, and the coolant is input into the first quick connector 321, and flows from the first quick connector 321 to the liquid inlet end of the charging gun, thereby providing the coolant to the charging gun and cooling the charging gun. The coolant enters the charging gun from the liquid inlet end of the charging gun, flows out of the charging gun from the liquid outlet end of the charging gun, and then flows into the second quick connector 322, and enters the second channel of the manifold block 310 from the second quick connector.

[0048] The first quick connector 321 and the second quick connector 322 can be easily plugged in and out of the pipe of the charging gun, so that they can be easily connected to each other.

[0049] Finally, the microchannel radiator 410 is described. The microchannel radiator 410 is vertically arranged and located on the side of the manifold block 310 away from the liquid storage tank 110. The liquid inlet end of the microchannel radiator 410 is connected to the second channel of the manifold block 310 to receive the coolant from the second channel and cool the coolant. The liquid outlet end of the microchannel is connected to the liquid inlet end of the liquid storage tank 110.

[0050] The coolant in the second channel of the manifold block 310 enters the microchannel radiator 410, which cools the coolant and then inputs the coolant into the liquid storage tank 110, so that the liquid storage tank 110 is continuously filled with low-temperature coolant to provide low-temperature coolant to the charging gun.

[0051] In the above small charging gun cooling device, the liquid storage tank 110 contains coolant, and the centrifugal pump 200 located below the liquid storage tank 110 extracts the coolant in the liquid storage tank 110. The centrifugal pump 200 inputs the coolant into the first channel of the manifold block 310. The coolant in the first channel enters the liquid inlet of the charging gun through the first quick connector 321, thereby cooling the charging gun and ensuring the good operation of the charging gun. The coolant after cooling the charging gun enters the second quick connector from the liquid outlet of the charging gun, enters the second chamber of the manifold block 310 from the first quick connector 321, and then enters the microchannel radiator 410 located on one side of the manifold block 310, cools the coolant through the microchannel, and inputs the coolant into the liquid storage tank 110, so that the coolant in the liquid storage tank 110 maintains a low temperature, and then provides the charging gun with a continuously low-temperature coolant, so that the charging gun operates well. This small charging gun cooling device has a compact structure, can be miniaturized, occupies a small space, has low power consumption, low cost, and stable operation.

[0052] In some embodiments of the utility model, the microchannel radiator 410 includes a lower header 413, a plurality of first flat tubes 412a and a plurality of second flat tubes 412b.

The upper header 411 is located directly above the lower header 413, and is connected to the second ends of the plurality of first flat tubes 412a and the plurality of second flat tubes 412b.

[0053] like Figure 2 As shown, the first chamber of the lower header 413 receives the coolant from the second channel of the manifold block 310, and inputs the coolant into the first flat tube 412a. The coolant in the first flat tube 412a flows upward into the upper header 411 and is horizontally transmitted. The coolant in the first flat tube 412a flows downward into the second flat tube 412b and then flows into the lower header 413. The coolant in the lower header 413 flows into the water tank, so that the coolant is circulated in the device. The heat exchange area of ​​the microchannel radiator 410 is large, which improves the cooling efficiency of the coolant. Moreover, this structure is compact and suitable for miniaturization.

[0054] Furthermore, the small charging gun cooling device includes a fan 420 . The fan 420 is arranged facing the micro-channel heat sink 410 .

[0058] The two fans 420 disposed above and below blow or suck air toward the micro-channel radiator 410, so that the wind force area can be enlarged to cover the entire micro-channel radiator 410, thereby increasing the intensity of convective heat exchange.

[0059] In some embodiments of the present invention, the small charging gun cooling device further includes a breathing valve 120. The breathing valve 120 is disposed on the top of the liquid storage tank 110.

[0061] In some embodiments of the present invention, the small charging gun cooling device further includes an oil mark 130 , which is disposed on a side of the liquid storage tank 110 .

[0062] like Figure 1 As shown, an oil mark 130 is provided on the side of the liquid storage tank 110. The liquid level of the coolant in the liquid storage tank 110 can be known through the oil mark 130.

[0063] In some embodiments of the present invention, the small charging gun cooling device further includes a liquid level switch 140. The liquid level switch 140 is inserted upward from the bottom of the liquid storage tank 110 into the liquid storage tank 110 to measure the liquid level of the coolant in the liquid storage tank.

[0066] like Figure 1 and Figure 3 As shown, the pressure of the coolant in the first channel can be obtained through the first pressure sensor 331, thereby knowing the pressure of the coolant to be input into the charging gun. The pressure of the coolant in the second channel can be obtained through the second pressure sensor 332, thereby knowing the pressure of the coolant output by the charging gun. Moreover, the operation of the centrifugal pump 200 is conveniently adjusted through the first pressure sensor 331 and the second pressure sensor 332 to maintain the stability of the pressure of the coolant provided to the charging gun.

[0067] According to some embodiments of the present invention, the small charging gun cooling device further includes a first temperature sensor 341 and a second temperature sensor 342 .

[0068] like Figure 1 and Figure 3 As shown, the temperature of the coolant in the first channel can be obtained through the first temperature sensor 341, thereby knowing the temperature of the coolant to be input into the charging gun. The temperature of the coolant in the second channel can be obtained through the second temperature sensor 342, thereby knowing the temperature of the coolant output by the charging gun. Moreover, the operation of the centrifugal pump 200 can be conveniently adjusted through the first temperature sensor 341 and the second temperature sensor 342 to maintain the temperature of the coolant provided to the charging gun stable.

[0069] In some embodiments of the present invention, the small charging gun cooling device further includes a housing, which is connected to the liquid storage tank 110 , the centrifugal pump 200 , the manifold block 310 and the microchannel radiator 410 .
