Description

Technical Field

[0001] The utility model relates to a car washing and charging integrated device and a system composed of the same, and the IPC classifications are B60S 3 / 04 and B60L53 / 00. Background Art

[0002] Usually, self-service car washers are mostly high-pressure cleaning machines, which use high-pressure pumps to connect water tanks and foam tanks to achieve the functions of spraying clean water and foam. Self-service car washers on the market are generally single-unit devices that can only be used by one user at a time. To a certain extent, they consume site costs and installation costs. If the car owner also needs to charge, it cannot meet the one-stop consumption needs of the car owner. Chinese patent CN205344848U discloses an Internet intelligent self-service car wash machine with a charging pile function, which is equipped with a control system and a charging gun, and the product realizes multiple uses of one machine.

[0003] However, the above scheme lacks comprehensive consideration on how to achieve the deep integration of charging and car washing functions, and at the same time improve the cleaning rate of car washing, reduce energy consumption and improve reliability.

[0004] For other relevant terms and common knowledge, please refer to the "Mechanical Engineering Handbook" and "Electrical Engineering Handbook" (Editorial Group, Machinery Industry Press, 2nd edition, 1997), and Chinese patent CN205344848U "Internet intelligent self-service car wash machine with charging pile function". Utility Model Content

[0005] In order to solve the problems described in the background technology, the utility model provides a car washing and charging integrated device, including a box body and a cleaning spray gun and a foam spray gun located on one side of the box body, and a charging gun located on the other side of the box body, and also includes:

[0006] - A charging unit, including a circuit breaker connected to a power source outside the box, a lightning arrester connected in parallel to the circuit breaker, and a charging module connected to the circuit breaker, wherein the charging module is connected to the charging gun;

[0007] -- a cleaning unit, comprising a clean water tank, a foam tank, and a high-pressure pump. The clean water tank is provided with a water level sensor for sensing the water level, and the foam tank is provided with a liquid level sensor for sensing the liquid level. The clean water tank and the foam tank are respectively connected to the input port of the high-pressure pump, and the output port of the high-pressure pump is respectively connected to the clean water spray gun and the foam spray gun through a hose;

[0008] - A cooling unit, including a first liquid-cooled heat exchanger in contact with the charging module, a cooling channel for conducting cooling liquid to flow to the first liquid-cooled heat exchanger to achieve heat exchange with the charging module, and a centrifugal pump for driving the cooling liquid to flow;

[0009] ——Control main board, receive induction signals, and control the electrical components of the above-mentioned charging unit, cleaning unit, and cooling unit to work simultaneously or in different time periods.

[0010] The cooling channel is a first cooling water channel formed by the first liquid-cooled heat exchanger being connected to the clean water tank through the water inlet and the water outlet of its pipeline. The first cooling water channel is also connected in series with a first centrifugal pump to drive the cleaning water in the clean water tank to circulate in the first cooling water channel. The cooling liquid is the cleaning water in the clean water tank.

[0011] The utility model adopts a cooling channel to conduct liquid to quickly reduce the temperature of the charging module, which can effectively avoid high-temperature failure of the charging module. In addition, the washing water used to wash the vehicle is used to cool the charging module, which can increase the temperature of the washing water, increase the activity of the detergent in the foam liquid, improve the cleaning rate (capacity) of the washing vehicle, reduce water and electricity consumption, and reduce energy consumption.

[0012] Furthermore, the cooling unit includes a condenser, a fan is provided on one side of the condenser for air cooling and heat dissipation, the pipe of the condenser is connected to the clean water tank to form a second cooling water channel, and the second cooling water channel is also connected in series with a second centrifugal pump to drive the flow of cleaning water in the clean water tank; or, the condenser is connected in series between the first liquid-cooled heat exchanger of the first cooling water channel and the clean water tank.

[0013] Preferably, the setting range of the cleaning water temperature of the clean water tank is 25-65 degrees, that is, higher than 65 degrees. The control mainboard starts the fan, and the centrifugal pump drives the cleaning water in the clean water tank to flow to the condenser for heat exchange and cooling. When the water temperature drops to 25 degrees, the fan is turned off for heat dissipation.

[0014] By controlling the cleaning water temperature of the clean water tank within a certain setting range, the activity of the detergent components in the foam can be guaranteed, and too high a temperature can be prevented from affecting the cooling performance of the charging module and causing safety problems for users.

[0015] Preferably, the cooling unit also includes a condenser, a heat exchanger, and a coolant tank containing coolant. The cooling channel is a fourth cooling channel formed by connecting the first liquid-cooled heat exchanger in series with the heat exchanger, the condenser, and the coolant tank. The fourth cooling channel is also connected in series with a fourth centrifugal pump to drive the coolant to flow. The cooling liquid is the coolant in the coolant tank.

[0016] Furthermore, the heat exchanger is also connected to the clean water tank to form a fifth cooling water channel. The fifth cooling water channel is serially connected with a fifth centrifugal pump to drive the cleaning water of the clean water tank to flow through the heat exchanger and the coolant in the fourth cooling channel to exchange heat.

[0017] The utility model adopts an independent fourth cooling channel to conduct coolant to lower the temperature of the charging module, which can effectively avoid high-temperature failure of the charging module; and further adopts a heat exchanger to connect with the clean water tank to form a fifth cooling water channel. The cleaning water of the clean water tank flows through the heat exchanger and the coolant in the fourth cooling channel to exchange heat. On the one hand, it can improve the ability to lower the temperature of the charging module, and on the other hand, it can increase the temperature of the cleaning water, increase the activity of the detergent in the foam liquid, improve the cleaning rate (capacity) of the cleaning vehicle, reduce water and electricity consumption, and reduce energy consumption.

[0018] Furthermore, the temperature of the coolant in the coolant tank is controlled to be no more than 65 degrees through condenser heat dissipation. If the coolant temperature exceeds 65 degrees, the charging module reduces the power of operation; the setting range of the cleaning water temperature of the clean water tank is 25-50 degrees. If it is higher than 50 degrees, the control main board stops the fifth centrifugal pump, and the coolant and the water in the clean water tank stop heat exchange. When the water temperature drops to 25 degrees, the fifth centrifugal pump is restarted, and the coolant and the water in the clean water tank continue heat exchange.

[0019] By monitoring the temperature of the coolant, the protection measures for the charging module can be effectively implemented, and the cleaning water temperature of the clean water tank can be controlled within a certain setting range, which can ensure the activity of the detergent components in the foam and avoid too high temperature affecting the cooling performance of the charging module and causing user safety problems.

[0020] Preferably, the inner cavity of the box body is separated by a partition and configured into an upper area, a first side area and a second side area. The charging module and the first liquid-cooled heat exchanger are assembled to form an integrated liquid-cooled charging module, which is isolated and placed in the upper area; the cleaning unit is isolated and placed in the first side area; the charging unit and the control mainboard are isolated and placed in the second side area. Placing the water channel components in isolated areas can avoid damage to the charging unit and the control mainboard caused by water leakage, thereby improving the reliability of the device.

[0021] Another preferred embodiment is that the inner cavity of the box body is separated by partitions to form a third side area and a fourth side area, and the charging module and the first liquid-cooled heat exchanger are assembled to form an integrated liquid-cooled charging module, and the liquid-cooled charging module and the cleaning unit are isolated and placed in the third side area; the charging unit and the control main board are isolated and placed in the fourth side area.

[0022] The above solution places the water-related components in an isolated partition from the charging unit and the control main board, which can avoid damage to the charging unit and the control main board caused by water leakage and improve the reliability of the device.

[0023] In addition, the utility model also provides a system composed of the above-mentioned car wash and charging integrated device, including a cooling tower and several of the above-mentioned car wash and charging integrated devices, the cooling tower is respectively connected to the first liquid-cooled heat exchanger of each car washing and charging integrated device to form a third cooling water channel, and the third cooling water channel is also connected in series with a third centrifugal pump to drive the cooling water flow of the cooling tower.

[0024] Preferably, the cooling water temperature is set to be no greater than 65 degrees. If the cooling water temperature exceeds 65 degrees, the charging module operates at reduced power.

[0025] The system composed of the car wash and charging integrated device of the utility model can control the temperature of the charging modules of several car wash and charging integrated devices within the set range through the cooling tower, which can avoid the impact of too high temperature on the cooling performance of the charging module and cause safety problems for users. This centralized water cooling solution can reduce the production and operation costs of a single car wash and charging integrated device, and the comprehensive energy consumption is lower.

DETAILED DESCRIPTION

[0039] As shown in the accompanying drawings, the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. When describing the device and system structure of the present invention, the side where the device operates the touch screen is referred to as the front or front side, and the opposite side is referred to as the rear or rear side. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Please refer to Figure 1 to Figure 2 As shown, it shows the specific structure of the embodiment 1 of the utility model of the integrated car washing and charging device, including a box body 1, an operation touch screen 5 arranged in the front of the box body, charging and car washing can be operated on the touch screen 5, considering that the hands will be wetted by water when washing the car, some specific implementations such as Figure 1 As shown, the physical buttons for washing hands / clean water / foam / settlement are still retained. A clean water spray gun 2 and a foam spray gun 3 for washing the vehicle are arranged on one side of the box, and a charging gun 4 is arranged on the other side of the box, and the charging gun 4 is used to charge the electric vehicle. Figure 2 for Figure 1 From the structural diagram after cutting open the front plate of the box body, it can be seen that the box body is divided into a first side area 11, a second side area 12 and an upper area 13 by the partition.

[0041] In the first side area 11, a cleaning unit 100 is provided. The cleaning unit 100 includes a clean water tank 101, a foam tank 102, a high-pressure pump 103, a first solenoid valve 104, and a second solenoid valve 105. A water level sensor 106 for controlling the water level is provided in the clean water tank 101, and a liquid level sensor 107 is provided in the foam tank 102. When the foam liquid is about to run out and the liquid in the barrel is lower than the set safety threshold, the liquid level sensor 107 sends a sensing signal and transmits the signal back to the control main board (to be introduced later). The control main board sends a signal to notify the user that a foaming agent needs to be added (which can be displayed on the operating touch screen). After adding a certain amount of foaming agent (the foam tank 102 is provided with an addition port, not shown in the figure), the ball valve 111 provided between the foam tank 102 and the water source is manually opened to fill the water in the tank. The water circuit diagram of a specific embodiment of the cleaning unit 100 is as follows: Figure 3 As shown, the input port of the first solenoid valve 104 is connected to the tap water source outside the box, the output port of the first solenoid valve 104 is connected to the clean water tank 101, and the clean water tank 101 is connected to the input port of the high-pressure pump 103; the input port of the second solenoid valve 105 is connected to the foam tank 102, and the output port of the second solenoid valve 105 is connected to the input port of the high-pressure pump 103; the output port of the high-pressure pump 103 is connected to the clean water spray gun 2 and the foam spray gun 3 through a hose. The water circuit diagram of another specific embodiment of the cleaning unit 100 is as follows Figure 4As shown, the cleaning unit 100 also includes a third solenoid valve 108 and an automatic dilution proportioning device 109. The input port of the first solenoid valve 104 is connected to the tap water source outside the box, and the output port of the first solenoid valve 104 is connected to the clean water tank 101. The clean water tank 101 is connected to the input port of the high-pressure pump 103 through the third solenoid valve 108; the second solenoid valve 105 is connected to the foam tank 102 through the automatic dilution proportioning device 109 (specifically, the input port of the second solenoid valve 105 is connected to the output port of the automatic dilution proportioning device 109, and one input port of the automatic dilution proportioning device 109 is connected to the foam tank 102), the other input port of the automatic dilution proportioning device 109 is connected to the clean water tank 101, and the output port of the second solenoid valve 105 is connected to the input port of the high-pressure pump 103. In other embodiments, the other input port of the automatic dilution proportioning device 109 can also be connected to the tap water source through the ball valve 111; the output port of the high-pressure pump 103 is connected to the clean water spray gun 2 and the foam spray gun 3 through a hose. The automatic dilution proportioning device 109 uses existing technology products, such as the proportioning machine of Jieruis. In other embodiments, a fully automatic water stop valve can also be set in the clean water tank 101, such as Shouli's 304FQF fully automatic water stop valve, which can automatically control the connection and disconnection between the clean water tank and the tap water source (realizing the joint function of the first electromagnetic valve 104 and the water level sensor 106). Specifically, when water enters the box body 1 and submerges the fully automatic water stop valve, the fully automatic water stop valve works, closes the water circuit, and stops adding water; when washing the car, once the water level is lower than the fully automatic water stop valve, the fully automatic water stop valve will open the water circuit and automatically add water. In this way, the cleaning unit 100 does not need to be provided with the first electromagnetic valve 104 and the water level sensor 106. Usually, on one side of the box body, the clean water spray gun 2 and the foam spray gun 3 are arranged, and the cleaning unit 100 is also provided with a faucet 401 for washing hands or cleaning rags, and the faucet is connected to the clean water tank 101 or the tap water source through the fourth solenoid valve 402.

[0042] In the second side area 12 and the upper area 13, a charging unit 200 connected to the charging gun 4 outside the box is provided. Figure 5As shown, it includes a circuit breaker 201 connected to the power supply outside the box, and a lightning arrester 202 connected in parallel with the circuit breaker 201. The lightning arrester 202 can filter out interfering peak current or voltage to prevent damage to the electrical components inside the charging pile. The circuit breaker 201 is preferably a residual current circuit breaker, such as Taiyong Changzheng MB50L-250 / 3320 250A A type, and the lightning arrester 202 uses existing technology products, such as RPM-40-3N+NPG calibrated in Chengdu; the charging unit 200 also includes a charging module 203 arranged in the upper area 13 and electrically connected to the circuit breaker 201. The charging module 203 is electrically connected to the charging gun 4. Preferably, a fuse 403 is also connected in series between the charging module 203 and the charging gun 4 to prevent overcurrent from damaging the electrical components inside the charging pile. An ammeter 402 is also connected in parallel in the above circuit to count the charging power. A control mainboard 300 is also disposed in the second side area 12, which is electrically connected to the electrical components of the cleaning unit 100 or the charging unit, and receives signals and issues instructions to implement the functions of the above-mentioned units.

[0043] The charging module 203 of this embodiment is a rectangular parallelepiped, and a first liquid-cooled heat exchanger 501 is installed on at least one side surface (preferably the side where the power element is located). The first liquid-cooled heat exchanger 501 includes a main body made of a metal with high thermal conductivity (such as aluminum, copper, etc.), and a folded pipe formed in the main body or attached and fixed to the main body. The first liquid-cooled heat exchanger 501 is in contact with the charging module 203, and the contact includes direct contact or indirect contact with a thermal conductive material such as thermal grease coated in the gap between them. In short, this contact is a heat-conducting contact that is conducive to the charging module 203 transferring the heat generated by the heat to the first liquid-cooled heat exchanger 501. The first liquid-cooled heat exchanger 501 is provided with a water inlet 502 and a water outlet 503. Preferably, as Figure 6 As shown, the first liquid-cooled heat exchanger 501 is in contact with and connected to the charging module 203, and is placed and fixed in a sealed chamber formed by an upper shell 521, a lower shell 522, and a sealing ring 523 to form an integrated liquid-cooled charging module 520, which facilitates modular production in advance and improves production efficiency.

[0044] like Figure 7As shown, the first liquid-cooled heat exchanger 501 (having formed an integrated liquid-cooled charging module 520) is connected to the clean water tank 101 through the water inlet 502 and the water outlet 503 to form a cooling unit 500 having a first cooling water channel 504. The first cooling water channel 504 is also connected in series with a first centrifugal pump 505 to drive the liquid to flow. The cleaning water of the clean water tank 101 flows through the first liquid-cooled heat exchanger 501, takes away the heat of the charging module 203, and at the same time increases the temperature of the cleaning water of the clean water tank 101. The cleaning water with a certain water temperature can improve the foam The activity of the detergent in the liquid can improve the cleaning rate of the car wash product, thereby reducing water and electricity consumption and reducing energy consumption; further, the cooling unit 500 also includes a condenser 506, and the condenser 506 also has a main body made of a metal with a high thermal conductivity (such as aluminum, copper, etc.), a fold-back pipe formed in the main body or attached to the main body, and a fan 509 is fixedly connected to one side of the condenser 506 for air cooling and heat dissipation. The condenser 506 can select existing technology products, such as the air-cooled series condensers of Foshan Keweili Refrigeration Equipment Co., Ltd. In this embodiment, the condenser 506 is connected in series between the first liquid-cooled heat exchanger 501 of the first cooling water channel 504 and the clean water tank 101, and is used to reduce the excessively high cleaning water temperature of the clean water tank 101 to a temperature that meets the set value range of 25°C-65°C. In other embodiments, such as Figure 8 As shown, the condenser can also be connected in parallel with the clean water tank through its return pipe to form an independent second cooling water channel 507, and the second cooling water channel 507 is connected in series with a second centrifugal pump 508 to drive the flow of cleaning water.

[0045] A temperature sensor 110 is provided in the clean water tank 101. The control range of the cleaning water temperature of the clean water tank is 25-65 degrees, that is, higher than 65 degrees. The control main board 300 condenser fan 509 drives the liquid in the clean water tank 101 to flow to the condenser 506 for heat exchange and cooling through a centrifugal pump. When the water temperature drops to 25 degrees, the fan 509 or the second centrifugal pump 508 is turned off, and the condenser 506 is stopped to actively dissipate heat and cool the liquid in the clean water tank 101.

[0046] The working process of the cooling unit 500 of this embodiment is as follows: when the user issues a charging command through the mobile phone or the touch screen, the control motherboard gives a signal to start charging, and at the same time the first centrifugal pump 505 starts working, using the cleaning water as the medium to transfer the heat of the liquid-cooled charging module to the cleaning water in the clean water tank. When the water temperature of the cleaning water in the clean water tank reaches the set upper limit temperature of 65°C, the temperature sensor detects the value and feeds it back to the control motherboard 300. The control motherboard 300 sends a signal to start the fan 509 (some embodiments also need to start the second centrifugal pump 508). The condenser exchanges heat with the cleaning water in the clean water tank to reduce the temperature of the cleaning water until the water temperature drops to the lower limit temperature of 25°C. The temperature sensor then feeds back a signal to the control motherboard, and the control motherboard sends a command to turn off the fan 509 or the second centrifugal pump 508, and stop the condenser 506 from actively dissipating heat and cooling the cleaning water in the clean water tank 101.

[0047] Fig. 9 The specific structure of the second embodiment of the utility model is shown. The second embodiment is a modified design of the first embodiment, and its main design difference lies in the partition design of the box body and the design of the cooling unit. It can be seen that the box body of the present embodiment is divided into a third side area 11' and a fourth side area 12' by a partition. The charging module 203 of the present embodiment is placed in a sealed chamber formed by the upper shell 521, the lower shell 522, and the sealing ring 523, and is fixed in contact with the first liquid-cooled heat exchanger 501 to form an integrated liquid-cooled charging module 520. The liquid-cooled charging module 520 is placed in the third side area 11' together with the cleaning unit 100. The other components of the charging unit 200, such as the circuit breaker 201, the lightning arrester 202, the electric meter 204, the fuse 205 and the control mainboard 300, are arranged in the fourth side area 12' to prevent leakage of water-related components and pipelines, and water droplets splashing onto the electrical components and the control mainboard 300 of the charging unit 200, affecting the safety of high-voltage or high-current charging electrical components.

[0048] The cooling unit 500 of this embodiment is designed as follows Fig.10As shown, the first liquid-cooled heat exchanger 501 is built into the liquid-cooled charging module 520 for cooling the charging module 203. The first liquid-cooled heat exchanger 501 is connected in series with the heat exchanger 513, the condenser 506, and the coolant tank 514 containing coolant to form a fourth cooling channel 515. The coolant temperature in the coolant tank 514 is set in the range of 25°C-65°C. Preferably, the fourth cooling channel 515 is connected in series with a fourth centrifugal pump 516 to drive the flow of the coolant. Furthermore, the heat exchanger 513 is also connected in parallel with the clean water tank 101 to form the fifth cooling water channel 517. The fifth cooling water channel 517 is also connected in series with the fifth centrifugal pump 518 to drive the cleaning water of the clean water tank 101 to flow through the heat exchanger 513. The cleaning water exchanges heat with the coolant of the fourth cooling channel 515 in the heat exchanger 513, indirectly absorbing the heat generated by the charging module 203, and at the same time increasing the temperature of the cleaning water in the clean water tank 101. The cleaning water with a certain water temperature can increase the activity of the detergent in the foam liquid and improve the cleaning rate of the product car washing, thereby reducing water and electricity consumption and reducing energy consumption. The heat exchanger 513 uses existing technology products, such as the plate heat exchanger of Guangzhou Chi Ri Heat Exchange Equipment Manufacturing Co., Ltd.

[0049] The working process of the cooling unit 500 of this embodiment is as follows: when the user issues a charging command through the mobile phone or the touch screen, the control mainboard sends a signal to start charging, and the cooling unit 500 starts working. The heat generated by the charging module 203 is carried by the coolant to the condenser 506 through the fourth cooling channel 515 for heat dissipation and cooling, thereby keeping the temperature of the charging module 203 within the working range of 25°C to 65°C. Furthermore, during the charging process, the fifth centrifugal pump 518 starts working, and the cleaning water in the clean water tank 101 also flows through the heat exchanger. At this time, the coolant and the cleaning water exchange heat in the heat exchanger, and the temperature of the cleaning water in the clean water tank 101 increases. When the temperature of the cleaning water in the clean water tank 101 reaches the set temperature of 50°C, the temperature sensor 110 detects the value and feeds it back to the control main board 300. The control main board 300 sends a signal to command the fifth centrifugal pump 518 to stop working, and the heat exchange between the coolant and the cleaning water in the heat exchanger stops; when the water temperature in the clean water tank 101 drops to 25°C, the temperature sensor 110 detects the value and feeds it back to the control main board 300. The control main board 300 sends a signal to start the fifth centrifugal pump 518, and the heat between the coolant and the cleaning water in the heat exchanger continues to be exchanged.

[0050] The control mainboard 300 of the integrated car washing and charging device of the present invention includes a basic function module and a network module, so as to connect to the Internet and control each unit to work simultaneously or in time-sharing manner through the Internet. The specific description is as follows:

[0051] When in use, the device is connected to a tap water source, and water supply and water cut-off of the device are realized through the first electromagnetic valve 104 and the water level sensor 106 (or a fully automatic water stop valve).

[0052] When the "Clean Water" button on the operation panel is pressed or the "Clean Water" function is selected through the touch screen, the control mainboard 300 starts the high-pressure pump 103 to pressurize and suck the cleaning water in the clean water tank 101, and sprays high-pressure cleaning water through the clean water spray gun 2 to realize the clean water flushing function. In some embodiments, the third solenoid valve 108 needs to be opened at the same time to realize the clean water flushing function. Press the "Clean Water" button again to turn off the high-pressure pump 103, disconnect the corresponding liquid circuit, and shut down the function of the clean water spray gun 2 to spray cleaning water. The water level of the cleaning water in the clean water tank 101 is monitored by the water level sensor. When the cleaning water level is lower than the preset lower limit of the water level sensor, the control mainboard 300 receives the water level sensor signal and controls the first solenoid valve 104 to open and connect the tap water source to replenish water in the clean water tank 101. When the water level of the cleaning water rises to the preset upper limit of the water level sensor, the first solenoid valve 104 is turned off to stop replenishing water to the clean water tank 101.

[0053] When the "foam" button on the operation panel is pressed or the "foam" function is selected through the touch screen, the control mainboard 300 starts the second electromagnetic valve 105 and the high-pressure pump 103, the liquid path connected to the foam box 102 is opened, and the high-pressure foam water is sprayed through the foam spray gun 3 to realize the foam adding function. Corresponding to the device with the dynamic dilution proportioner 109, the foam stock liquid in the foam box 102 leading to the automatic dilution proportioner 109 is extracted, enters the cavity of the automatic dilution proportioner 109, and after mixing with the cleaning water from the clean water tank 101 in the cavity, it is passed to the high-pressure pump 103 for pressurization, and then the high-pressure foam is sprayed through the foam spray gun 3 to realize the foam adding function. Press the "foam" button again, the second electromagnetic valve 105 and the high-pressure pump 103 are closed, the corresponding liquid path is disconnected, and the foam adding function is turned off.

[0054] When the electric car needs to be charged, the charging gun 4 is connected to the electric car. When the user issues a charging command through the mobile phone or the touch screen, when the control mainboard 300 receives the charging command, the circuit breaker 201 is connected to the three-phase power supply. After the three-phase power supply passes through the circuit breaker 201, it enters the charging module 203. The main function of the charging module 203 is to convert the three-phase AC power into DC power. Since the charging module abandons the traditional air cooling mode and uses liquid cooling instead, the temperature of the charging module 203 is controlled between 25°C and 65°C. Once the temperature of the charging module exceeds 65°C, the power operation will be reduced, which can effectively avoid the over-temperature failure of the charging module. The AC power is converted into DC power through rectification by the liquid-cooled charging module, and then the car is charged through the charging gun to complete the charging function;

[0055] A specific implementation of the utility model car washing and charging integrated system is as follows Fig.11As shown, it includes several car wash and charging integrated devices, which are not provided with the above-mentioned first cooling water channel 504, second cooling water channel 507, fourth cooling water channel 515, and fifth cooling water channel 517. Instead, the liquid-cooled charging modules of each car wash and charging integrated device are connected in series with the cooling tower 510 through their water inlet 502 and water outlet 503 to form independent third cooling water channels 511. Each third cooling water channel 511 is connected in series with a third centrifugal pump 512 to drive the cooling water of the cooling tower 510 to circulate in each corresponding third cooling water channel 511. The heat generated by the charging module 203 is brought to the cooling tower 510 by the cooling water through the third cooling water channel 511 for heat exchange. The water level of the cooling water is set in the range of 25°C to 65°C, so that the temperature of the charging module 203 can be kept in the working range of 25°C to 65°C. Once the temperature of the charging module exceeds 65°C, the power operation will be reduced, which can effectively avoid the over-temperature failure of the charging module.

[0056] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several deformations and improvements can be made, such as not setting strict partitions in the box or only waterproofing and isolating the pipe connectors and functional components connecting the waterway, etc., which are all feasible and fall within the scope of protection of the utility model.
