DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0044] Next, the liquid cooling device of the charging gun according to the embodiment of the utility model is described.

[0045] like Figures 1 to 3 As shown, the charging gun liquid cooling device of the embodiment of the utility model includes: a mounting plate 100 , a water tank 210 , a water pump 700 , a fan 300 and a microchannel radiator 400 .

[0046] First, the mounting plate 100 is described. The mounting plate 100 includes a first surface and a second surface facing each other, and a plurality of mounting holes 110 are formed on the mounting plate 100 so that fasteners can pass through the second surface from the first surface of the mounting plate 100 and be fixedly connected to the outside. The fasteners may be bolts, studs, screws, pins, etc.

[0047] The mounting plate 100 provides stable support for other components, and the mounting holes 110 are exposed. When it is necessary to hang or install it outside (outside the charging gun liquid cooling device), the mounting plate 100 is fixed to the outside by fasteners passing through the mounting holes 110.

[0048] Optionally, the mounting hole 110 is a calabash hole. A screw can be inserted into a predetermined position of the side plate of the charging station, with a predetermined gap between the head of the screw and the side plate, and then the calabash hole of the mounting plate 100 is buckled into the screw, so that the mounting plate 100 is suspended, which is convenient for disassembly and installation.

[0049] Next, the water tank 210 and the water pump 700 are described. The water tank 210 is disposed on the upper portion of the first surface of the mounting plate 100, and the coolant can be contained therein. The water pump 700 is disposed on the first surface of the mounting plate 100 and is located below the water tank 210. The liquid inlet end of the water pump 700 is connected to the liquid outlet end of the water tank 210, and the liquid outlet end of the water pump 700 is used to connect to the liquid inlet end of the charging gun.

[0050] The water pump 700 draws coolant from the water tank 210 and delivers the coolant to the liquid inlet of the charging gun, thereby cooling the charging gun.

[0051] Next, the fan 300 and the microchannel radiator 400 are described. The fan 300 is horizontally arranged on the first surface of the mounting plate 100 and is located on the left or right side of the water tank 210 and the water pump 700. The mounting plate 100 is hollowed out at the position corresponding to the fan 300. The microchannel radiator 400 is arranged on the surface of the fan 300 away from the mounting plate 100. The liquid inlet end of the microchannel radiator 400 is used to connect to the liquid outlet end of the charging gun, and its liquid outlet end is connected to the liquid inlet end of the water tank 210.

[0052] After the coolant enters the charging gun, the charging gun is cooled, and the temperature of the coolant increases. The heated coolant enters the microchannel radiator 400, and the heat is dissipated through the microchannel radiator 400, so that the temperature of the coolant is reduced. The coolant cooled by the microchannel radiator 400 flows into the water tank 210 again.

[0053] The fan 300 faces the micro-channel radiator 400 , thereby performing forced convection heat exchange on the micro-channel radiator 400 , thereby accelerating the cooling of the coolant in the micro-channel radiator 400 .

[0054] Optionally, there are multiple fans 300, and the multiple fans 300 are arranged vertically and spaced apart.

[0055] like Figure 1 , two upper and lower fans 300 are provided. The number of fans 300 is not limited here. Multiple fans 300 can increase wind force and improve cooling efficiency.

[0056] In the above charging gun liquid cooling device, the first surface of the mounting plate 100 is provided with a water tank 210, a water pump 700, a fan 300 and a microchannel radiator 400. The mounting plate 100 is formed with a mounting hole 110 penetrating the first surface and the second surface thereof. The mounting hole 110 is exposed, so that the fastener can pass through the mounting hole 110 and be fixedly connected to the outside, which is convenient for the installation or hanging of the mounting plate 100. The water pump 700 extracts the coolant from the water tank 210 and inputs the coolant into the liquid inlet end of the charging gun. The coolant cools the charging gun. The liquid inlet end of the microchannel radiator 400 receives the coolant from the charging gun and cools the coolant. The fan 300 blows / sucks air to the microchannel radiator 400 to increase the cooling efficiency of the coolant in the microchannel radiator 400. The charging gun liquid cooling device with this structure has a compact structure, high cooling efficiency and is easy to hang or install.

[0057] In some embodiments of the utility model, the charging gun liquid cooling device also includes a manifold block 510. The manifold block 510 is connected to the microchannel radiator 400, and a first cavity and a second cavity that are independent of each other are formed inside the manifold block 510. The first end of the first cavity is connected to the liquid outlet of the water pump 700 and its second end is connected to the charging gun through the first connector 521. The liquid outlet of the water pump 700 is connected to the liquid inlet of the charging gun through the first cavity of the manifold block 510. The first end of the second cavity is used to connect the charging gun and its second end is connected to the microchannel radiator 400 through the second connector 531. The liquid inlet of the microchannel heat dissipation is connected to the liquid outlet of the charging gun through the second cavity of the manifold block 510.

[0058] That is, the charging gun liquid cooling device is connected to the charging gun through the manifold block 510. The liquid outlet of the water pump 700 is connected to the liquid inlet of the charging gun through the first cavity of the manifold block 510 and the first connector 521, and the liquid inlet of the microchannel radiator 400 is connected to the liquid outlet of the charging gun through the second cavity of the manifold block 510 and the second connector 531. The provision of the manifold block 510 can facilitate the docking of the charging gun liquid cooling device with the charging gun, and make the charging gun liquid cooling device more compact and simple.

[0059] Furthermore, the first connector 521 and the second connector 531 are both multi-way connectors.

[0060] like Figure 3 As shown, the first connector 521 and the second connector 531 are both three-way connectors, which can simultaneously provide coolant to two charging guns. It should be noted that the above are only optional examples, and there is no limitation on multi-way connectors, which can also be four-way connectors, six-way connectors, etc.

[0061] Further, the charging gun liquid cooling device also includes a plurality of first hoses 522, a plurality of first clamping joints 523, a plurality of second hoses 532 and a plurality of second clamping joints 533. The first ends of the plurality of first hoses 522 are respectively connected to the first joints 521. The plurality of first clamping joints 523 correspond to the plurality of first hoses 522 one by one, the first clamping joints 523 are connected to the second ends of the first hoses 522, and the first joints 521 are connected to the liquid inlet ends of the plurality of charging guns through the plurality of first hoses 522 and the plurality of first clamping joints 523. The first ends of the plurality of second hoses 532 are respectively connected to the second joints 531. The plurality of second clamping joints 533 correspond to the plurality of second hoses 532 one by one, the second clamping joints 533 are connected to the second ends of the second hoses 532, and the second joints 531 are connected to the liquid outlet ends of the plurality of charging guns through the plurality of second hoses 532 and the plurality of second clamping joints 533.

[0062] like Figure 3 As shown, the charging gun liquid cooling device includes two first hoses 522, two first clamping joints 523, two second hoses 532 and two second clamping joints 533. That is, one end of the three-way joint is connected to the manifold block 510, and the other two ends are connected to two hoses respectively. The number of hoses (first hose 522 and second hose 532) is not limited here, and it depends on the joints (first joint 521 and second joint 531). For example, if the first joint 521 is six-way, the corresponding first hose 522 is five. Among them, the hose can be a nylon tube, a rubber tube, etc.

[0063] The first clamping connector 523 and the second clamping connector 533 can facilitate quick connection and disassembly of the charging gun liquid cooling device and the pipeline of the charging gun.

[0064] The hose is easier to bend and has higher flexibility. During the process of taking, placing, plugging and unplugging the charging gun, the hose can be moved and bent adaptively, that is, the flexible connection between the charging gun liquid cooling device and the charging gun increases the stability and service life of the connection, and avoids the situation where the rigid connection between the charging gun liquid cooling device and the charging gun (non-hose hard tube) is easy to separate and wear.

[0065] Furthermore, the charging gun liquid cooling device also includes a first temperature sensor 551 and a second temperature sensor 541. The first temperature sensor 551 is inserted into the first cavity of the manifold block 510 to detect the first temperature of the coolant in the first cavity. The second temperature sensor 541 is inserted into the second cavity of the manifold block 510 to detect the second temperature of the coolant in the second cavity.

[0066] like Figure 3 As shown, the first temperature sensor 551 is inserted into the first cavity of the manifold block 510, so as to detect the first temperature of the coolant to be input into the charging gun. The second temperature sensor 541 is inserted into the second cavity of the manifold block 510, so as to detect the second temperature of the coolant output from the charging gun. Based on the first temperature and / or the second temperature, the rotation speed of the water pump 700 and the rotation speed of the fan 300 can be conveniently adjusted, so as to provide the charging gun with a stable temperature of the coolant, thereby increasing the stability of the cooling of the charging gun.

[0067] Furthermore, the charging gun liquid cooling device also includes a first pressure sensor 552 and a second pressure sensor 542. The first pressure sensor 552 is inserted into the first cavity of the manifold block 510 to detect the first pressure of the coolant in the first cavity. The second pressure sensor 542 is inserted into the second cavity of the manifold block 510 to detect the second pressure of the coolant in the second cavity.

[0068] like Figure 3 As shown, the first pressure sensor 552 is inserted into the first cavity of the manifold block 510, so as to detect the first pressure of the coolant in the first cavity. The second pressure sensor 542 is inserted into the second cavity of the manifold block 510, so as to detect the second pressure of the coolant in the first cavity. Based on the first pressure and the second pressure, it is convenient to connect the pressure of the coolant in the pipeline, and it is convenient for the water pump 700 to adjust the speed, so as to avoid the situation where the cooling effect is reduced due to insufficient pressure of the coolant, or to avoid the situation where the coolant delivery pipeline is broken due to excessive pressure of the coolant.

[0069] In some embodiments of the present invention, the charging gun liquid cooling device further includes a drain pipe 610 and a drain valve 620. The drain pipe 610 is connected to the first cavity of the manifold block 510. The drain valve 620 is connected to the drain pipe 610 to open or close the drain pipe 610.

[0070] like Figure 1and Figure 3 As shown, when the coolant needs to be replaced, it is only necessary to open the drain valve 620, and the coolant in the water tank 210 and the manifold block 510 can flow out from the drain pipe 610. Thus, the coolant in the water tank 210 and the manifold block 510 can be easily discharged.

[0071] In some embodiments of the present invention, a threaded hole is formed on the top of the water tank 210, and the charging gun liquid cooling device also includes a breathing valve 240, which is threadedly connected to the threaded hole.

[0072] like Figure 1 As shown, when it is necessary to add coolant to the water tank 210, the breathing valve 240 is rotated and taken out, the coolant is injected from the threaded hole, and then the breathing valve 240 is rotated and locked. Moreover, the thermal expansion and contraction of the coolant will cause the pressure in the water tank 210 to change. The breathing valve 240 can allow the water tank 210 to exchange gas with the outside world to prevent the water tank 210 from bursting and deforming.

[0073] Furthermore, the charging gun liquid cooling device also includes an oil mark 220 and a liquid level sensor 230. The oil mark 220 is arranged on the surface of the water tank 210 away from the mounting plate 100 and is located at the upper part of the water tank 210. The liquid level sensor 230 is inserted upward from the bottom of the water tank 210 into the interior of the water tank 210 to detect the liquid level of the coolant in the water tank 210.

[0074] like Figure 1 As shown, the coolant in the water tank 210 can be detected by the liquid level sensor 230 or checked by the oil mark 220, so as to adjust and replenish the coolant in time. Moreover, when the coolant is injected into the water tank 210, the coolant level can be obtained in time by the oil mark 220.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
