Detailed implementation manner

[0049] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0050] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0051] Next, the cooling device of the new energy charging pile according to the embodiment of the present utility model will be described.

[0052] As Figures 1 to 3 shown, the cooling device of the new energy charging pile according to the embodiment of the present utility model includes: a fixed plate 100, a water tank 210, a water pump 300, a manifold block 400, a flow sensor 510, a first pipeline, a second pipeline, a cooling device, and an alarm.

[0053] First, the fixed plate 100, the water tank 210, and the water pump 300 will be described. The fixed plate 100 is arranged vertically. The water tank 210 is arranged above the fixed plate 100, and the water tank 210 can hold the coolant. The water pump 300 is arranged on the fixed plate 100 and below the water tank 210, and the liquid inlet end of the water pump 300 is connected to the liquid outlet end of the water tank 210.

[0054] As Figure 1As shown, the fixing plate 100 can stably support other components and is convenient for movement. The water tank 210 accommodates the coolant, thereby providing the coolant. The water pump 300 can extract the coolant in the water tank 210 to make the coolant flow smoothly.

[0055] Next, the manifold block 400, the flow sensor 510 and the first pipeline will be described. The manifold block 400 has a first chamber 410 and a second chamber 420 formed therein. The liquid inlet end of the first chamber 410 is connected to the liquid outlet end of the water pump 300. The liquid inlet end of the flow sensor 510 is connected to the liquid outlet end of the first chamber 410 to detect the flow rate of the coolant. The liquid inlet end of the first pipeline is connected to the liquid outlet end of the flow sensor 510, and its liquid outlet end is used to connect to the liquid inlet end of the charging gun.

[0056] As Figure 1 and Figure 2 shown, the manifold block 400 includes a first chamber 410 and a second chamber 420 arranged vertically. The first chamber 410 and the second chamber 420 can respectively provide independent accommodation spaces for the coolant, reducing the number of components and having a simple structure.

[0057] The water pump 300 pumps the coolant into the first chamber 410, flows into the flow sensor 510, then into the first pipeline, and then into the liquid inlet end of the charging gun. The flow sensor 510 can accurately detect the flow rate of the coolant.

[0058] Then, the second pipeline and the cooling device will be described. The liquid inlet end of the second pipeline 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 second chamber 420. The cooling device is arranged on the fixing plate 100 and is located on the side of the water tank 210. The liquid inlet end of the cooling device is connected to the liquid outlet end of the second chamber 420, and its liquid outlet end is connected to the liquid inlet end of the water tank 210.

[0059] After the coolant cools the charging gun, it flows into the second pipeline, then into the cooling device. The cooling device cools down the coolant, and then it flows back to the water tank 210, thereby realizing a cyclic flow.

[0060] Finally, the alarm will be described. The alarm is connected to the flow sensor 510 to give an alarm according to the fact that the flow rate of the coolant detected by the flow sensor 510 is lower than a predetermined value.

[0061] When the first pipeline and / or the second pipeline is bent, the greater the degree of bending, the smaller the cross-sectional area of the coolant at the bent part, and the lower the flow rate. When the flow rate drops to a predetermined value, it indicates that the first pipeline and / or the second pipeline is bent too much. At this time, the pump is still running, and the pressure of the coolant borne by the equipment is very high, which poses a greater risk to the equipment (such as coolant pipeline bursting, coolant leakage, etc.). At this time, the alarm gives an alarm, which can remind relevant personnel to deal with it in time (such as shutting down the equipment, etc.), so as to avoid equipment failure and improve the safety of the equipment.

[0062] For the above cooling equipment of the new energy charging pile, the fixing plate 100 provides stable support for other components. The water pump 300 extracts the coolant from the water tank 210 and inputs it into the first chamber 410 of the manifold block 400, and then flows from the first chamber 410 into the flow sensor 510. The flow sensor 510 detects the flow rate of the coolant. The coolant flows through the flow sensor 510 to the first pipeline and then into the liquid inlet end of the charging gun. The coolant flows through the charging gun to cool the charging gun, enabling the charging gun to operate stably, and then flows into the second pipeline. The coolant flows from the second pipeline into the cooling device, and the cooling device cools the coolant and then flows back to the water tank 210, thus realizing the circulating flow of the coolant. When the first pipeline and / or the second pipeline is bent, the greater the degree of bending, the smaller the cross-sectional area of the coolant at the bent part, and the lower the flow rate. When the flow rate drops to a predetermined value, it indicates that the first pipeline and / or the second pipeline is bent too much. At this time, the pump is still running, and the pressure of the coolant borne by the equipment is very high, which poses a greater risk to the equipment. At this time, the alarm gives an alarm, which can remind relevant personnel to deal with it in time (such as shutting down the equipment, etc.), so as to avoid equipment failure and improve the safety of the equipment.

[0063] In some embodiments of the present invention, the cooling equipment of the new energy charging pile further includes a controller. The controller is connected to the water pump 300 and the flow sensor 510. The controller controls the water pump 300 to stop running according to the fact that the flow rate of the coolant detected by the flow sensor 510 is lower than the predetermined value.

[0064] When the flow sensor 510 monitors that the flow rate of the coolant is lower than the predetermined value, the pressure of the coolant borne by the equipment is very high, which poses a greater risk to the equipment. Through the controller, the water pump can be timely shut down, that is, even when there is no one on duty, the water pump 300 can be timely shut down, which can avoid equipment failure, has a high degree of automation, and has higher safety.

[0065] In some embodiments of the present utility model, there are two flow sensors 510. The two flow sensors 510 are connected to the first chamber 410 at intervals. The first pipeline includes two first round tubes 520 and two liquid outlet connectors 530. The first ends of the two first round tubes 520 are correspondingly connected to the liquid outlet ends of the two flow sensors 510 respectively. The two liquid outlet connectors 530 are correspondingly connected to the liquid outlet ends of the two first round tubes 520 respectively. The first pipeline is connected to the liquid inlet ends of the two charging guns through the two liquid outlet connectors 530.

[0066] As Figure 1 and Figure 2 shown, through the two flow sensors 510, the two first round tubes 520 and the two liquid outlet connectors 530, coolant can be provided for the two charging guns, and the two charging guns can be cooled synchronously, improving the equipment utilization rate.

[0067] The liquid inlet end of the charging gun can be connected more simply through the liquid outlet connector 530.

[0068] Furthermore, the second pipeline includes two second round tubes 610 and two liquid inlet connectors 620. The two second round tubes 610 are arranged at intervals. The second pipeline is connected to the liquid inlet end of the second chamber through the liquid outlet ends of the two second round tubes 610. The two liquid inlet connectors 620 are respectively and correspondingly connected to the liquid inlet ends of the two first round tubes. The second pipeline can be connected to the liquid outlet ends of the two charging guns through the two liquid inlet connectors 620.

[0069] As Figure 1 and Figure 2 shown, through the two second round tubes 610 and the two liquid inlet connectors 620, the coolant flowing out of the two charging guns can be received synchronously, realizing the circulating cooling of the two charging guns.

[0070] The liquid outlet end of the charger can be simply connected through the liquid inlet connector 620.

[0071] In some embodiments of the present utility model, the cooling device includes a fan 710 and a microchannel radiator 720. The fan 710 is arranged on the fixing plate 100 and its air inlet / outlet direction is perpendicular to the fixing plate 100. The fixing plate 100 forms air holes at the position corresponding to the fan 710. The microchannel radiator 720 is arranged on the side of the fan 710 facing away from the fixing plate 100. The cooling device is connected to the liquid outlet end of the second chamber 420 and the liquid inlet end of the water tank 210 through the microchannel radiator 720.

[0072] The microchannel radiator 720 has a large heat dissipation area. The coolant passes through the microchannel radiator 720, and the heat dissipation efficiency is high. The fan 710 performs forced convection heat transfer on the microchannel radiator 720, thereby dissipating and cooling the coolant in the microchannel radiator 720, further improving the heat dissipation efficiency of the coolant.

[0073] Furthermore, the microchannel radiator 720 includes a lower header 721, a plurality of first flat tubes 722, an upper header 723, and a second flat tube 724. The lower header 721 is formed with independent first and second cavities 721a and 721b. The microchannel radiator 720 is connected to the second chamber 420 through the liquid inlet end of the first cavity 721a, and the microchannel radiator 720 is connected to the water tank 210 through the liquid outlet end of the second cavity 721b. A plurality of first flat tubes 722 are arranged vertically, and the liquid inlet ends of all the first flat tubes 722 are connected to the first cavity 721a. The liquid inlet end of the upper header 723 is connected to the liquid outlet ends of all the first flat tubes 722. A plurality of second flat tubes 724 are arranged vertically, and the plurality of second flat tubes 724 are spaced apart from the plurality of first flat tubes 722. The liquid inlet ends of all the second flat tubes 724 are connected to the liquid outlet end of the upper header 723, and their liquid outlet ends are connected to the liquid inlet end of the second cavity 721b.

[0074] As Figure 3 shown, the microchannel radiator 720 includes a lower header 721, a plurality of first flat tubes 722, an upper header 723, and a second flat tube 724. The coolant flows out from the liquid outlet end of the second chamber 420 and sequentially passes through the first cavity 721a of the lower header 721, all the first flat tubes 722, the upper header 723, all the second flat tubes 724, and the second cavity 721b of the lower header 721, and finally enters the liquid inlet end of the water tank 210 from the second cavity 721b. The cooling path through which the coolant flows is relatively long, and the cooling efficiency is relatively high, which can sufficiently cool the coolant. Moreover, the overall structure occupies a relatively small space and is relatively compact, which can improve the utilization rate of space.

[0075] In some embodiments of the present utility model, the cooling device of the new energy charging pile further includes a drain pipe 810 and a drain valve 820. The liquid inlet end of the drain pipe 810 is connected to the bottom of the water tank 210. The drain valve 820 is connected to the liquid outlet end of the drain pipe 810.

[0076] As Figure 1 shown, the drain pipe 810 is connected to the bottom of the water tank 210, and the drain valve 820 is provided at the bottom end of the drain pipe 810. Opening the drain valve 820 can cause the coolant in the water tank 210 to flow out, facilitating the drainage of the cooling device.

[0077] In some embodiments of the present utility model, the cooling device of the new energy charging pile further includes a breather valve 220. The breather valve 220 communicates with the water tank 210.

[0078] As Figure 1As shown in the figure, a breather valve 220 is provided at the top of the water tank 210. Through the breather valve 220, the water tank 210 can exchange air with the outside world, avoiding the damage of the water tank 210 caused by thermal expansion and contraction in a closed environment, thereby increasing the service life of the equipment.

[0079] In some embodiments of the present invention, the cooling device of the new energy charging pile further includes a first temperature sensor 540 and a first pressure sensor 550. The first temperature sensor 540 is connected to the first chamber 410 to detect the first temperature of the coolant in the first chamber 410. The first pressure sensor 550 is connected to the first chamber 410 and spaced apart from the first temperature sensor 540 to detect the first pressure of the first chamber 410.

[0080] As Figure 1 and Figure 2 shown in the figure, a first temperature sensor 540 and a first pressure sensor 550 are provided on the first chamber 410 of the manifold block 400. Through the first temperature sensor 540, the first temperature of the coolant in the first chamber 410 can be accurately obtained, and through the first pressure sensor 550, the first pressure of the coolant in the first chamber 410 can be accurately obtained, which is convenient for the cooling device to input coolant that meets the temperature and pressure requirements to the charging gun.

[0082] As Figure 1 shown in the figure, a second temperature sensor 630 and a second pressure sensor 640 are provided on the second chamber 420 of the manifold block 400. Through the second temperature sensor 630, the second temperature of the coolant in the second chamber 420 can be accurately obtained, and through the second pressure sensor 640, the second pressure of the coolant in the second chamber 420 can be accurately obtained, which is convenient for accurately obtaining the temperature and pressure of the coolant flowing out of the charging gun.

[0083] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
