DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model 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 numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0037] In order to solve the above technical problems, Figure 1 As shown, an embodiment of the utility model provides a water cooling device, including a liquid flow component and a liquid cooling structure 1, wherein the liquid flow component includes a liquid replenishing structure 2, a pumping structure 3 and a condensing structure 4, the liquid cooling structure 1 has a first liquid outlet 101 and a first liquid inlet 102, the first liquid outlet 101 is connected to the first liquid inlet 102 via the condensing structure 4 and the pumping structure 3 to form a heat dissipation component, and the liquid replenishing structure 2 is connected to the heat dissipation component.

[0038] It should be noted that the liquid flow component can be arranged at the pile end, wherein the pile end refers to a place with control equipment such as a charging gun and an operation panel. The pile end can be arranged on a column similar to an AC charging pile, or can be installed at a location such as a wall of a building; the liquid cooling structure 1 and the transmitting device 12 can be arranged at the ground end, and the ground end refers to a ground end device that can wirelessly charge the electric vehicle through wireless coupling.

[0039] At least a portion of the liquid cooling structure 1 is used to connect with the transmitting device 12 of the wireless charging system. At least a portion of the liquid cooling structure 1 is connected with the transmitting device 12, which can be understood as follows: if the power device 11 of the wireless charging system is set at the pile end, the entire liquid cooling structure 1 can be in contact and connected with the transmitting device 12; or, if the power device 11 of the wireless charging system and the liquid cooling structure 1 are both set at the ground end, a portion of the liquid cooling structure 1 is connected with the transmitting device 12, and another portion of the liquid cooling structure 1 can be connected with the power device 11, so that the power device 11 and the transmitting device 12 can be cooled and dissipated at the same time through the liquid cooling structure 1.

[0040] During normal operation of the water cooling device, the coolant can circulate in the heat dissipation component composed of the liquid flow component and the liquid cooling structure 1. When the flow rate of the coolant is reduced and cannot meet the heat dissipation demand of the emitting device 12, the heat dissipation component can be connected through the liquid cooling structure 1 to replenish the coolant in the liquid cooling structure 1 into the heat dissipation component, so that there is a sufficient flow of coolant in the heat dissipation component to achieve normal heat dissipation operation of the emitting device 12.

[0041] in, Figure 1The medium-thick solid line represents the normal flow path of the coolant in the heat dissipation assembly, while the thin solid line represents the flow direction of the coolant added into the heat dissipation assembly.

[0042] The liquid cooling structure 1 can be a plate-like structure with a flow channel inside, or a tubular structure that can be arranged around the emitting device, and the first liquid outlet 101 and the first liquid inlet 102 are respectively connected to the hollow inner cavity of the liquid cooling structure 1, which is not specifically limited here.

[0043] In this embodiment, the water cooling device mainly includes a liquid flow component and a liquid cooling structure 1, wherein the liquid flow component can be arranged at the pile end, and the transmitting device 12 and the liquid cooling structure 1 can be arranged at the ground end, and the liquid flow component at the pile end can be connected to the liquid cooling structure 1 at the ground end through a pipeline. Since at least part of the liquid cooling structure 1 is connected to the transmitting device 12, the coolant in the liquid cooling structure 1 can absorb the heat generated by the transmitting device 12 during operation, and then under the action of the pumping structure 3 in the heat dissipation component, such as a water pump, the coolant that absorbs the heat flows out through the first liquid outlet 101 of the liquid cooling structure 1, and when flowing through the condensation structure 4, the coolant can be cooled by the condensation structure 4, and then the cooled coolant flows back to the liquid cooling structure 1 through the pumping structure 3 and the first liquid inlet 102, and this process is continuously circulated to achieve at least the cooling operation of the transmitting device 12 in the wireless charging system.

[0044] When the coolant in the heat dissipation component is short of and needs to be replenished, the replenishing structure 2 is connected to the heat dissipation component so that the coolant in the replenishing structure 2 can enter the heat dissipation component from a certain position to realize the replenishment operation of the coolant in the heat dissipation component, thereby ensuring that there is a sufficient flow of coolant in the heat dissipation component for the normal cooling operation of the emitting device 12.

[0045] In one embodiment of the present invention, Figure 2 , Figure 3 and Figure 7 As shown, the liquid replenishing structure 2 includes a liquid replenishing container 21 and a first three-way pipe 22, the first three-way pipe 22 has a first end, a second end and a third end that are interconnected, and in the heat dissipation component, the first liquid outlet 101 is connected to the first liquid inlet 102 via the condensation structure 4, the first end, the second end, and the pumping structure 3 in sequence;

[0046] The fluid replenishment container 21 has an outlet 212 , and the outlet 212 of the fluid replenishment container 21 is connected to the liquid cooling structure 1 via the third end, the second end, the pumping structure 3 , and the first liquid inlet 102 in sequence to form a fluid replenishment assembly.

[0047] It should be noted that the first three-way pipe 22 can be a three-way pipe joint structure, and the first three-way pipe 22 has three pipe joints, which can be defined as a first end, a second end and a third end, respectively, wherein the first end and the second end can be connected to the condensation structure 4 and the pumping structure 3, respectively, so the first three-way pipe 22 is used to connect the outlet 212 of the fluid replenishment container 21 and the pumping structure 3, as well as the condensation structure 4 and the pumping structure 3.

[0048] Combination Figure 2 As shown, when the coolant in the heat dissipation component circulates, the coolant in the liquid cooling structure 1 can flow out from the first liquid outlet 101 under the suction force of the pumping structure 3, and enter the liquid cooling structure 1 through the condensation structure 4, the first end, the second end, the pumping structure 3, and the first liquid inlet 102 in sequence, thereby realizing the circulation operation of the coolant in the above-mentioned heat dissipation component. The flow path of the coolant in the heat dissipation component can be referred to Figure 2 The symbol of the medium thick solid arrow. Figure 2 The dotted line between the middle liquid replenishing container 21 and the second three-way pipe 42 indicates that during normal cooling operation (ie, no liquid replenishing), the liquid replenishing container 21 may not participate in the circulation of the above-mentioned coolant.

[0049] The refill container 21 is used to hold the coolant, such as a refill pot, a refill bottle, etc., and the coolant can be added to the heat dissipation component in the following manner: Figure 3 As shown, for example, the coolant in the liquid replenishment container 21 flows out from the outlet 212, enters the pumping structure 3 through the third end and the second end of the first three-way pipe 22 in sequence, and then enters the liquid cooling structure 1 through the pumping structure 3 and the first liquid inlet 102 to achieve the liquid replenishment operation of the coolant in the heat dissipation component. The flow path of the liquid replenishment container 21 to replenish the coolant in the heat dissipation component can be referred to Figure 3 The logo of the medium thin solid arrow.

[0050] In one embodiment of the present invention, Figure 2 , Figure 3 and Figure 7 As shown, the liquid replenishing structure 2 further includes a valve structure 23, the condensing structure 4 includes a condenser 41 and a second three-way pipe 42, the second three-way pipe 42 has a fourth end, a fifth end and a sixth end that are interconnected, and the first liquid outlet 101 is connected to the condenser 41 through the fourth end and the fifth end;

[0051] The liquid replenishing container 21 further has an inlet 211 , and the sixth end is connected to the inlet 211 via the valve structure 23 .

[0052] It should be noted that the second three-way pipe 42 is a three-way pipe joint structure, and the second three-way pipe 42 has three pipe joints, which can be defined as the fourth end, the fifth end and the sixth end, respectively, wherein the fourth end and the fifth end can be connected to the first liquid outlet 101 and the condenser 41 respectively, and the sixth end is connected to the valve structure 23, so the second three-way pipe 42 is used to connect the first liquid outlet 101 of the liquid cooling structure 1 and the condenser 41, as well as the first liquid outlet 101 and the valve structure 23.

[0053] When the liquid replenishing container 21 replenishes the cooling liquid in the heat dissipation component for circulation, the cooling liquid in the liquid replenishing container 21 can be replenished in the following manner. For example, under the suction force of the pumping structure 3, the cooling liquid in the liquid replenishing container 21 flows out from the outlet 212, and enters the liquid cooling structure 1 through the third end, the second end, the pumping structure 3, and the first liquid inlet 102 of the first three-way pipe 22 in sequence, and then flows out from the first liquid outlet 101 of the liquid cooling structure 1 through the fourth end, the sixth end, and the valve structure 23 of the second three-way pipe 42 through the inlet 211 to return to the liquid replenishing container 21, so as to realize the circulation operation of the replenished cooling liquid, and the flow path of the replenished cooling liquid can refer to Figure 3 The logo of the medium thin solid arrow.

[0054] exist Figure 3 The dotted lines between the middle condenser 41 and the first three-way pipe 22 and the second three-way pipe 42 indicate that during liquid replenishment, the condenser 41 may not participate in the circulation of the above-mentioned coolant.

[0055] In one embodiment of the present invention, Figure 7 As shown, the liquid replenishing container 21 further has an exhaust port 213 , and the outlet 212 is located below the exhaust port 213 .

[0056] It should be noted that, since the outlet 212 is located below the exhaust port 213 , the coolant in the liquid replenishing container 21 will not leak from the exhaust port 213 .

[0057] Since the liquid replenishing container 21 has an exhaust port 213, the air in the entire heat dissipation pipeline can be exhausted during the first liquid replenishment. Figure 3 and Figure 7 As shown, the valve structure 23 is opened, and under the action of the pumping structure 3, the coolant in the liquid replenishing container 21 flows out from the outlet 212, and enters the liquid cooling structure 1 through the third end, the second end, the pumping structure 3, and the first liquid inlet 102 of the first three-way pipe 22 in sequence, and then flows out from the first liquid outlet 101 of the liquid cooling structure 1 through the fourth end, the sixth end, the valve structure 23 of the second three-way pipe 42 in sequence, and the inlet 211 into the liquid replenishing container 21. In other words, during the first liquid replenishing process, the exhaust port is in an open state, and the coolant flowing out of the first liquid outlet will not enter the condenser after passing through the second three-way pipe (see Figure 3As shown, the condenser does not participate in the refilling operation during the first refilling, so the condenser and the second three-way pipe are indicated by a dotted line), and directly flows back to the refilling container through the valve structure, so that when the replenished coolant flows in the pipelines between the above-mentioned components, the air in the pipeline can be effectively squeezed into the refilling container 21, and the air is discharged from the exhaust port 213 of the refilling container 21, thereby effectively reducing the refilling noise generated by the air in the pipeline in the subsequent refilling operations after the first refilling.

[0058] Of course, after the first refilling, when the second or even multiple refillings are performed, the condenser can participate in the normal refilling operation. At this time, the refilling operation and the cooling operation of the emitting device by the coolant in the heat dissipation component can be carried out simultaneously.

[0059] After the refilling operation is finally completed, that is, the refilled coolant at least meets the heat dissipation demand of the emitting device, the valve structure 23 can be closed at this time, and the refilling container no longer participates in the normal circulation of the coolant in the heat dissipation component to dissipate heat for the emitting device (see Figure 2 shown).

[0060] Furthermore, the exhaust port 213 can also be used as a refill port. For example, when it is found during the refill process that the coolant inside the refill container 21 is insufficient to be replenished into the heat dissipation component (i.e., the coolant capacity inside the refill container 21 is too small), new coolant can be added to the refill container 21 through the exhaust port 213 (refill port) to avoid affecting the refill effect due to insufficient coolant in the refill container 21.

[0061] In one embodiment of the present invention, Figure 7 and Figure 8 As shown, the liquid flow component also includes a water inlet pipe 5 and a water outlet pipe 6 , the first liquid outlet 101 is connected to the fourth end via the water inlet pipe 5 , and the pumping structure 3 is connected to the first liquid inlet 102 via the water outlet pipe 6 .

[0062] It should be noted that, since the liquid flow component is arranged at the pile end, and the liquid cooling structure 1 is arranged at the ground end, there is a certain distance between the pile end and the ground end, so the water inlet pipe 5 and the water outlet pipe 6 can be used as the water inlet pipe 5 and the water outlet pipe 6 of the liquid flow component respectively, and one end of the water inlet pipe 5 is connected to the fourth end of the second three-way pipe 42 arranged in the pile end, and the other end is connected to the first liquid outlet 101 of the liquid cooling structure 1 in the ground end; one end of the water outlet pipe 6 is connected to the water outlet end of the pumping structure 3 arranged in the pile end, and the other end is connected to the first liquid inlet 102 of the liquid cooling structure 1 in the ground end, so the water inlet pipe 5 and the water outlet pipe 6 are used to connect the water cooling device at the pile end and the liquid cooling structure 1 at the ground end.

[0063] In one embodiment of the present invention, Figure 2 , Figure 3 and Figure 5As shown, the condenser 41 has a second liquid inlet 412 and a second liquid outlet 411. In the heat dissipation assembly, the first liquid outlet 101 is connected to the first liquid inlet 102 via the fourth end, the fifth end, the second liquid inlet 412, the second liquid outlet 411, and the pumping structure 3;

[0064] In the fluid replenishing assembly, the first end and the second end of the first three-way pipe 22 correspond to the second liquid outlet 411 of the condenser 41 and the pumping structure 3 respectively, and the position of the second liquid outlet 411 is lower than the position of the second liquid inlet 412.

[0065] It should be noted that when the coolant in the heat dissipation component circulates, it can be done in the following manner. For example, under the action of the pumping structure 3, the coolant in the liquid cooling structure 1 flows out from the first liquid outlet 101, and enters the condenser 41 through the fourth end of the second three-way pipe 42 and the fifth end from the second liquid inlet 412, and then flows out from the second liquid outlet 411 of the condenser 41, and then enters the liquid cooling structure 1 through the first end, the second end, the pumping structure 3, and the first liquid inlet 102 of the first three-way pipe 22, thereby realizing the circulation operation of the coolant in the above-mentioned heat dissipation component.

[0066] You can add new coolant to the heat dissipation component in the following ways: Figure 3 As shown, for example, the coolant in the liquid replenishment container 21 flows out from the outlet 212 and is divided through the first three-way pipe 22 in sequence. One stream of coolant enters the liquid cooling structure 1 through the pumping structure 3 and the first liquid inlet 102, and the other stream of coolant flows to the second liquid outlet 411 of the condenser 41. At this time, since the position of the second liquid outlet 411 is lower than the position of the second liquid inlet 412 (see Figure 7 As shown), during the refilling operation, the added coolant cannot enter the condenser 41 due to gravity, which not only realizes the exhaust operation of the air in the pipelines between the components, but also improves the refilling efficiency of the liquid cooling structure 1.

[0067] In one embodiment of the present invention, Figures 4 to 6 As shown, the liquid flow component further includes a pile end housing 7 and a fan 8 , the liquid replenishing structure 2 , the pumping structure 3 and the condensing structure 4 are arranged in the pile end housing 7 , and the fan 8 is arranged opposite to the condensing structure 4 .

[0068] It should be noted that the liquid replenishing structure 2, the pumping structure 3 and the condensation structure 4 are arranged in the pile end shell 7, which can constitute the pile end equipment of the wireless charging system, and the pile end shell 7 can also be used to provide safety protection for the liquid replenishing structure 2, the pumping structure 3 and the condensation structure 4; since the fan 8 is arranged relative to the condensation structure 4, the condensation structure 4 can be blown by the fan 8, and the flow speed of the air around the condensation structure 4 can be accelerated to improve the heat exchange efficiency between the coolant in the condensation structure 4 and the surrounding air, thereby realizing the rapid cooling operation of the coolant in the heat dissipation component.

[0069] Figure 4 , Figure 5 and Figure 6 The sizes of the pile end housing 7 are different, so the pile end housing 7 of different sizes can be flexibly selected according to the wireless charging systems of different models and powers.

[0070] The pile end housing 7 also includes a shell 71 and an end cover 72 . An opening may be provided on the shell 71 so that the liquid replenishing structure 2 , the pumping structure 3 and the condensing structure 4 can be installed in the shell 71 through the opening and packaged by the end cover 72 .

[0071] In one embodiment of the present invention, Figure 5 As shown, the fluid flow assembly further includes a dustproof structure 14 . A heat dissipation hole may be provided on the pile end housing 7 . The dustproof structure 14 may be installed between the heat dissipation hole and the fan 8 .

[0072] It should be noted that the dustproof structure 14 can be installed between the heat dissipation hole and the fan 8, so that the dust impurities entering the pile end housing 7 from the heat dissipation hole can be filtered through the dustproof structure 14 to prevent the dust from entering the inside of the fan 8, thereby reducing the maintenance and cleaning frequency of the water cooling device. The dustproof structure 14 can be a dustproof net structure.

[0073] The water cooling device also includes a fan speed control switch, which is electrically connected to the fan 8. The fan speed control switch can adjust the cooling effect on the coolant by adjusting the speed of the fan 8 according to factors such as the temperature of the water cooling device and the ground.

[0074] The water cooling device also includes a power switch 13, which can be installed in the pile end housing 7. The input end of the power switch 13 can be connected to the mains switch, and the output end of the power switch 13 can be electrically connected to the pumping structure 3, the fan 8, etc., so as to supply power to the pumping structure 3 and the fan 8.

[0075] When the power device 11 is set at the ground end, the output end of the power switch 13 is also electrically connected to the power device 11 and the transmitting device 12 through a cable to provide power to the power device 11 and the transmitting device 12.

[0076] In addition, combined Figure 4 and Figure 5 As shown, the water cooling device also includes a wireless communication module 9, which is installed on the pile end housing 7. At least one of the fan 8, the pumping structure 3, and the power device 11 can be electrically connected to the input end of the wireless communication module 9 through a signal line, and the output end of the wireless communication module 9 can be connected to a display device, so that at least one electrical signal (such as rotation speed, working voltage, current, etc.) of the fan 8, the pumping structure 3, and the power device 11 can be wirelessly transmitted to the display device through the wireless communication module 9, so that the staff can understand the working status data of the fan 8, the pumping structure 3, and the power device 11 in real time.

[0077] The wireless communication module 9 may be at least one of WiFi, 4G, and Bluetooth.

[0078] Of course, an emergency stop switch is provided on the pile end housing 7, and the emergency stop switch is electrically connected to the power switch 13. When a fault occurs in the water cooling device, the power supply of the relevant components in the water cooling device can be quickly shut off by the emergency stop switch to avoid the expansion of the fault.

[0079] The utility model also provides a wireless charging system, comprising the water cooling device as described above, and also comprising a transmitting device 12, wherein the transmitting device 12 is used for wireless connection with a receiving device arranged on a vehicle.

[0080] It should be noted that the transmitting device 12 is wirelessly connected to the receiving device on the vehicle so that the two can realize wireless charging of the vehicle, such as an electric car, by wireless coupling.

[0081] In one embodiment of the present invention, Fig. 9 As shown, the wireless charging system also includes a ground end shell 10 and a power device 11, the transmitting device 12, the liquid cooling structure 1 of the water cooling device and the power device 11 are respectively installed in the ground end shell 10, and the transmitting device 12 and the power device 11 are respectively connected to the liquid cooling structure 1.

[0082] It should be noted that, in the related art, the power device 11 is usually installed in the pile end housing 7, and the transmitting device 12 is installed in the ground end housing 10. At this time, the power device 11 and the transmitting device 12 are electrically connected through the excitation line, which not only increases the volume of the pile end equipment, but also because the excitation line is exposed, it is easy to be scratched, crushed, etc. by foreign objects, which may cause safety hazards. Moreover, the exposed excitation line may also affect the normal operation of surrounding devices due to the generation of magnetic field, thereby affecting the normal operation of the wireless charging system.

[0083] However, usually, the pile end is installed on a building such as a wall, which has a relatively high space requirement. Therefore, by installing the power device 11 in the ground end housing 10, the volume of the pile end housing 7 can be reduced to reduce the volume of the pile end equipment, thereby meeting the requirements of installing the pile end equipment in a place with limited space; furthermore, installing both the power device 11 and the transmitting device 12 in the ground end housing 10 can also greatly shorten the length of the excitation line to reduce the cost of using the excitation line, and can also reduce heat generation and energy consumption.

[0084] The transmitting device 12, the liquid cooling structure 1 and the power device 11 are respectively integrated and installed in the ground end housing 10 to form a ground end device, and the ground end device can be installed at the location where the electric vehicle is charged. Among them, the power device 11, the transmitting device 12 and the liquid cooling structure 1 can be stacked in the vertical direction, or the power device 11 and the transmitting device 12 can be arranged horizontally and installed on the upper part of the liquid cooling structure 1, or the liquid cooling structure 1 can be installed around the power device 11 and the transmitting device 12. As long as the arrangement method that the liquid cooling structure 1 can simultaneously dissipate heat and cool the power device 11 and the transmitting device 12 is satisfied, it is applicable to the present technical solution, and no specific limitation is made here.

[0085] The emitting device 12 and the power device 11 are connected to the liquid cooling structure 1 , so that the liquid cooling structure 1 can simultaneously perform heat dissipation and temperature reduction operations on the emitting device 12 and the power device 11 by means of heat conduction.

[0086] Among them, the input ends of the power device 11 and the transmitting device 12 can be connected to the power switch 13 to perform heat dissipation and cooling operations on the power device 11 and the transmitting device 12 through the power switch 13. The output end of the power device 11 is electrically connected to the transmitting device 12, so the power device 11 is used to convert the AC power of the city power into high-frequency AC power and transmit it to the transmitting device 12, and the transmitting device 12 is wirelessly coupled to the receiving device, and the receiving device is used to convert the received high-frequency electric energy into a DC power of a voltage level, and then convert the DC power of a voltage level into another voltage level of DC power and charge the battery pack of the electric vehicle to realize wireless charging of the battery pack of the vehicle. Therefore, the technical solution of wireless charging of the electric vehicle through the power device 11 and the transmitting device 12 is a prior art, and only a brief overview is given here without limitation.

[0087] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
