Description

Technical Field

[0001] The utility model relates to the technical field of liquid-cooled charging piles, in particular to a liquid replenishing mechanism for a liquid-cooled charging pile. Background Art

[0002] A liquid-cooled charging pile is a type of charging pile that uses liquid circulation cooling to cool the battery. The liquid-cooled charging pile mainly adopts annular heat pipe technology. Through the circulation of heat-conducting liquid, the temperature of the charging pile battery is always maintained within an appropriate range, thereby achieving the purpose of fast charging. The liquid cooling system is divided into open system, semi-open system and sealed system.

[0003] According to Chinese patent publication number CN209159450U, an automatic refilling liquid-cooled charging pile is disclosed. This patent uses a liquid storage element, a liquid pump, a solenoid valve, a temperature sensor, and a pressure sensor to facilitate refilling, solving the problem of inconvenient refilling in existing liquid-cooled charging piles. It is very practical. However, this patent still has certain shortcomings in actual use. Since the coolant inside the liquid-cooled charging pile is continuously output and input during operation, and the input coolant is continuously heat-exchanged, resulting in a certain difference between the temperature of the newly input coolant and the temperature of the coolant during operation. After the new coolant is added and mixed together, the heat exchange work cannot be completed quickly to make the coolant temperature uniform and stable. As a result, for a period of time after refilling, the temperature of some output coolant is different from the temperature during normal circulation, which affects the liquid cooling effect during this period. In response to this, the present application is based on allowing the newly input coolant to quickly match the working coolant to meet the normal cooling working requirements, thereby proposing a refilling mechanism for a liquid-cooled charging pile.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 3The utility model provides a technical solution: a liquid replenishing mechanism for a liquid-cooled charging pile, comprising a mounting frame 1, a liquid cooling mechanism 200 mounted on the inner side of the mounting frame 1, and a liquid replenishing component 300 mounted on the inner side of the mounting frame 1 for replenishing coolant into the liquid cooling mechanism 200; through the coordinated use of the liquid cooling mechanism 200 and the liquid replenishing component 300 mounted on the inner side of the mounting frame 1, the replenished coolant can be quickly mixed and matched with the coolant in the working process, so that the newly replenished coolant can be pre-mixed with the working coolant in advance, and through the effect of heat exchange, the temperature of the coolant newly entering the working process can be quickly matched and mixed, so that the liquid cooling effect will not be excessively affected during the replenishment process, so that the cooling work can be carried out normally, thereby effectively improving the practicality of the liquid replenishing mechanism of the liquid-cooled charging pile.

[0024] In this embodiment, the liquid cooling mechanism 200 is a structure for performing liquid cooling.

[0025] like Figure 1 and Figure 2 As shown, the liquid cooling mechanism 200 includes a liquid storage tank 201 fixedly installed on the inner side of the mounting frame 1, a plurality of connecting pipes 202 passing through and fixedly installed on the outer side of the liquid storage tank 201, a first water pump 203 fixedly installed on the outer side of the connecting pipes 202, and a first liquid level sensor 204 fixedly installed on the inner side of the liquid storage tank 201.

[0026] It should be noted that the bottom end of the connecting pipe 202 extends to the bottom of the inner side of the liquid storage tank 201. The number of connecting pipes 202 is even and is divided into an output pipe and an input pipe. The coolant is output from the inside of the liquid storage tank 201 through the output pipe for liquid cooling, and then input into the inside of the liquid storage tank 201 through the input pipe. A cooling mechanism for cooling the coolant is installed on the outside of the input pipe. Among them, the output and input of the coolant and the cooling technology are all existing publicly available technologies, so they will not be elaborated on.

[0027] In this embodiment, the liquid replenishing assembly 300 is a structure for replenishing the cooling liquid of the liquid cooling mechanism 200 .

[0028] like Figure 1 、 Figure 2 and Figure 3As shown, the fluid replenishment assembly 300 includes a fluid replenishment tank 301 fixedly mounted on the inner side of the mounting frame 1, a premixing tank 302 fixedly mounted on the inner side of the mounting frame 1, a first delivery pipe 303 fixed between the fluid replenishment tank 301 and the opposite side of the premixing tank 302, two first control valves 304 fixedly mounted on the outside of the first delivery pipe 303, a second delivery pipe 305 fixed on the other side of the premixing tank 302, two second control valves 306 fixedly mounted on the outside of the second delivery pipe 305, two second water pumps 307 fixedly mounted on the outside of the first delivery pipe 303 and the second delivery pipe 305 respectively, an intake pipe 308 passing through and fixed to the top of the premixing tank 302, a heat exchange pipe 309 fixed to the other end of the intake pipe 308, and a third water pump 310 fixedly mounted on the outside of the intake pipe 308.

[0029] It should be noted that the second delivery pipe 305 is fixedly connected to the outside of the liquid storage tank 201 and is internally connected. The two first control valves 304 are respectively located on the outside of the premixing tank 302 and the outside of the liquid replenishing tank 301, and the two second control valves 306 are respectively located on the outside of the premixing tank 302 and the outside of the liquid storage tank 201, so that the coolant inside the liquid storage tank 201 can be transported through the second delivery pipe 305. Under the action of the first control valve 304 and the second control valve 306, the two ends of the first delivery pipe 303 and the second delivery pipe 305 can be controlled to open and close respectively, wherein the coolant can be output to the interior of the premixing tank 302 under the action of the second water pump 307.

[0030] In addition, the heat exchange tube 309 has a spiral shape, which gives it a larger contact area and is conducive to rapid heat exchange. An extension plate is fixed to the back of the liquid storage tank 201 for fixed connection to the outside of the third water pump 310, so that the third water pump 310 can work stably. And because the third water pump 310 is arranged at a position close to the liquid storage tank 201, the coolant inside the suction tube 308 can fully pass through the third water pump 310 into the interior of the heat exchange tube 309.

[0031] In addition, a second liquid level sensor is fixedly installed on the inner side of the rehydration tank 301 and the premixing tank 302, so that the liquid level inside them can be monitored, which facilitates the rehydration work and enables the staff to easily judge the liquid level of the coolant inside the rehydration tank 301, so as to replenish it during regular maintenance.

[0032] It should also be noted that several fixing plates 401 are fixed to the outside of the heat exchange tube 309, and a support rod 402 is fixed to the side of the fixing plate 401 away from the heat exchange tube 309. The heat exchange tube 309 is located inside the liquid storage tank 201, and the other end of the support rod 402 is fixedly connected to the inner side of the liquid storage tank 201. The number of fixing plates 401 is not less than four, so that under the supporting effect of the support rod 402 and the fixing effect of the fixing plate 401, the heat exchange tube 309 can be stably installed inside the liquid storage tank 201, wherein the heat exchange tube 309 is a pipe with strong thermal conductivity such as an aluminum alloy tube.

[0033] The working principle of the above embodiment is:

[0034] During the replenishment, the first liquid level sensor 204 can monitor the liquid level inside the liquid storage tank 201. When the liquid level is lower than the preset value, the two second water pumps 307 and the first control valve 304 and the second control valve 306 are started, so that the coolant inside the liquid storage tank 201 and the liquid replenishment tank 301 are both input into the premixing tank 302, and premixed during the simultaneous input process, so that the newly added coolant can be mixed with the working coolant in advance and heat exchange is carried out. After the input is completed, the third water pump 310 is started, so that the coolant inside the premixing tank 302 is input into the heat exchange pipe 309 through the suction pipe 308, and fully exchanges heat with the coolant inside the liquid storage tank 201 during the circling transportation inside the heat exchange pipe 309. Finally, after being discharged into the liquid storage tank 201 through the heat exchange pipe 309, the temperature of the coolant in each area inside the liquid storage tank 201 can be kept relatively uniform and stable, which is conducive to the normal and stable operation of liquid cooling.

[0035] Compared with the existing technology, the refilling mechanism of the liquid-cooled charging pile, through the cooperation between the liquid cooling mechanism 200 installed on the inner side of the mounting frame 1 and the refilling assembly 300, can quickly mix and match the replenished coolant with the coolant in the working process, so that the newly replenished coolant can be pre-mixed with the working coolant in advance, and through the effect of heat exchange, the temperature of the coolant newly entering the working process can be quickly matched and mixed, so that the liquid cooling effect will not be excessively affected during the refilling process, so that the cooling work can be carried out normally, thereby effectively improving the practicality of the liquid-cooled charging pile refilling mechanism, and solving the problem that the existing automatic refilling liquid-cooled charging pile is prone to cause the temperature of the newly entered coolant to be mismatched with the coolant in the working process during the refilling process, which will affect the liquid cooling effect for a certain period of time.

The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field.
