Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and more specifically, to a heat dissipation device and a wireless charging device. Background Technology

[0002] As a modern means of transportation, automobiles have gradually become common in every household, becoming an important part of our family life and bringing us much convenience for our daily travel. However, the main energy source used by automobiles is petroleum products, and the engine cannot completely burn gasoline, emitting a large amount of exhaust gas into the atmosphere, which seriously pollutes the human living environment.

[0003] To conserve energy and reduce environmental pollution, electric vehicles are being increasingly promoted. Electric vehicles use electricity as their energy source and an electric motor as their driving force, producing no exhaust emissions and having no pollution or impact on the atmospheric environment. Currently, electric vehicles primarily use batteries as energy storage devices to provide power to the motor. Therefore, when the battery discharges to a critical point, it needs to be recharged. There are currently two methods for charging electric vehicles: wired charging and wireless charging.

[0004] Wired charging: Charging is completed by connecting the charging gun to the car's charging interface, just like refueling a car, except that it is converted from gasoline to electric. Because there is a power supply cable connected to the charging gun, it is called wired charging.

[0005] Wireless charging: This method charges a car through electromagnetic induction. A transmitter is installed on the ground, and a receiver is installed in the car. Energy is transferred between them through electromagnetic induction to charge the battery. Because it is a non-contact charging method, it is called wireless charging.

[0006] However, current wireless charging suffers from insufficient heat dissipation during use. Specifically, automotive wireless charging consists of an energy exchange system composed of transmitting and receiving coils. Electric vehicles require high power, long driving range, and are equipped with a large number of battery packs. Therefore, to ensure normal operation and high utilization rate of the vehicle, a high-power charging system is needed to guarantee the charging time and efficiency of the battery. As the charging power increases, the current passing through the coil in the transmitting device will increase accordingly, and the temperature of the coil will rise accordingly. The higher the power, the higher the temperature rise. The existing natural heat dissipation and air cooling modes can no longer meet the requirements. Utility Model Content

[0007] The problem this invention aims to solve is: how to improve the heat dissipation efficiency of the ground transmitter for wireless charging of high-power electric vehicles.

[0010] The heat dissipation device of this invention comprises a condenser tube assembly and a fan arranged opposite each other inside the housing.

A liquid cooling plate is disposed within the transmitting device, and the liquid cooling plate and the condenser tube assembly are connected by a circulation pipe. The condenser tube assembly and the liquid cooling plate circulate their internal coolant through the circulation pipe. For example, during operation, the transmitting device generates heat, which heats the coolant in the liquid cooling plate. The high-temperature coolant in the liquid cooling plate flows through the circulation pipe to the condenser tube assembly for heat dissipation. Simultaneously, the low-temperature coolant in the condenser tube assembly flows through the circulation pipe to the liquid cooling plate for heat dissipation of the transmitting device. This continuous circulation provides sustained water cooling for the transmitting device.

It is only for the convenience of describing this utility model and is not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0035] Furthermore, in the attached diagram, the Z-axis represents the vertical direction, that is, the up and down position, and the positive direction of the Z-axis (that is, the direction the arrow points to) represents up, and the negative direction of the Z-axis (that is, the direction opposite to the positive direction of the Z-axis) represents down; in the attached diagram, the X-axis represents the horizontal direction, that is, the left and right position, and the positive direction of the X-axis (that is, the direction the arrow points to) represents left, and the negative direction of the X-axis (that is, the direction opposite to the positive direction of the X-axis) represents right.

[0036] It should also be noted that the meanings of the aforementioned Z-axis and X-axis are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0037] With the increasing popularity of wireless charging technology for electric vehicles, it is becoming more convenient and safer than wired charging because it eliminates the need for plugging and unplugging a charging gun. Wireless charging technology is based on inductive coupling, where energy is exchanged between a transmitting component and a receiving coil.

[0038] The power supply unit (transmitter 100) of existing wireless charging devices suffers from insufficient heat dissipation. Furthermore, with continuously increasing power, the existing products' natural heat dissipation and air cooling modes are no longer sufficient to meet the demands.

[0039] Based on this, such as Figures 1 to 2 As shown, the heat dissipation device of this utility model embodiment includes: a housing 1, a fan 2, a condenser tube assembly 3, a circulation pipeline, and a liquid cooling plate 4. The condenser tube assembly 3 and the fan 2 are respectively disposed inside the housing 1, and the air outlet of the fan 2 is arranged facing the condenser tube assembly 3. The liquid cooling plate 4 is used to be disposed inside the transmitter 100 of the wireless charging device. The circulation pipeline is connected to the condenser tube assembly 3 and the liquid cooling plate 4 respectively, and the condenser tube assembly 3 and the liquid cooling plate 4 are used to circulate the coolant inside them through the circulation pipeline.

[0040] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 2As shown, a condenser tube assembly 3 and a fan 2 are arranged opposite each other inside the housing 1 (the air outlet of the fan 2 faces the condenser tube assembly 3). The air blown by the fan 2 is directed towards the condenser tube assembly 3 to cool the coolant inside the condenser tube assembly 3. A liquid cooling plate 4 is installed inside the launching device 100 and is connected to the condenser tube assembly 3 by a circulation pipe. The coolant inside the condenser tube assembly 3 and the liquid cooling plate 4 can circulate through the circulation pipe. For example, the launching device 100 generates heat during operation, which heats the coolant in the liquid cooling plate 4. The high-temperature coolant in the liquid cooling plate 4 can flow through the circulation pipe to the condenser tube assembly 3 for heat dissipation and cooling. Then, the low-temperature coolant in the condenser tube assembly 3 can flow through the circulation pipe to the liquid cooling plate 4 to exchange heat with the launching device 100 again. This cycle can continuously cool the launching device 100. Compared with related technologies, the heat dissipation device of this utility model has higher heat dissipation efficiency, can dissipate heat from the wireless charging ground transmitter more quickly, and has a longer maintenance cycle and service life compared with air cooling.

[0041] It should be noted that in the initial working state of this heat dissipation device, the fan 2 is in a non-working state. As the transmitter 100 of the wireless charging device continues to work, its temperature gradually rises. When the temperature exceeds the set value, the fan 2 starts to work. Similarly, when the transmitter 100 switches from the working state to the non-working state and its temperature drops to the set value, the fan 2 stops working.

[0042] Optionally, the heat dissipation device further includes a liquid storage tank 6, which is disposed inside the housing 1 and is used to store coolant;

[0043] The circulation pipeline includes a first connecting pipe 51, a second connecting pipe 52, and a third connecting pipe 53. The two ends of the first connecting pipe 51 are respectively connected to the liquid storage tank 6 and the condenser tube assembly 3. The two ends of the second connecting pipe 52 are respectively connected to the condenser tube assembly 3 and the liquid cooling plate 4. The two ends of the third connecting pipe 53 are respectively connected to the liquid storage tank 6 and the liquid cooling plate 4.

[0044] In this embodiment, in conjunction with the appendix Figure 2 As shown, a liquid storage tank 6 is provided inside the shell 1, and at the upper end of the liquid storage tank 6 (attached) Figure 2 A liquid injection port 61 can be provided in the positive Z-axis direction, wherein the liquid injection port 61 extends upward to the outside of the housing 1, and coolant can be injected into the liquid storage tank 6 through the liquid injection port 61. (See attached diagram) Figure 1 and attached Figure 2As shown, the liquid storage tank 6 and the condenser tube assembly 3 can be connected by a first connecting pipe 51, and the coolant in the liquid storage tank 6 can be transported to the condenser tube assembly 3 through the first connecting pipe 51. The condenser tube assembly 3 and the liquid cooling plate 4 can be connected by a second connecting pipe 52, and the coolant in the condenser tube assembly 3 can be transported to the liquid cooling plate 4 through the second connecting pipe 52. The liquid storage tank 6 and the liquid cooling plate 4 can be connected by a third connecting pipe 53, and the coolant in the liquid cooling plate 4 can be transported to the liquid storage tank 6 through the third connecting pipe 53.

[0045] In other embodiments, in conjunction with the appendix Figure 2 As shown, a water pump 94 is installed inside the housing 1. A first connecting pipe 51 is connected to the water pump 94. The coolant in the storage tank 6 can be pumped to the condenser tube assembly 3 through the water pump 94 and the first connecting pipe 51. Then, the coolant in the condenser tube assembly 3 can be transported to the liquid cooling plate 4 through the second connecting pipe 52. Then, the coolant in the liquid cooling plate 4 can be transported to the storage tank 6 through the third connecting pipe 53. This cycle repeats continuously to provide water cooling for the launching device 100.

[0046] In other embodiments, in conjunction with the appendix Figure 2 As shown, a liquid level sensor 91 can be installed on the liquid storage tank 6 to detect whether there is liquid inside the liquid storage tank 6, so as to ensure the normal operation of the system.

[0047] In other embodiments, in conjunction with the appendix Figure 2 As shown, a pressure sensor 93 can be installed on the liquid storage tank 6 to detect the pressure of related pipelines and ensure the normal operation of the system.

[0048] In other embodiments, in conjunction with the appendix Figure 1 As shown, a control board 92 can be installed on the housing 1. The water pump 94 and the fan 2 can be electrically connected to the control board 92 respectively. The speed of the fan 2 and the water pump 94 can be controlled by the control board 92. The speed of the fan 2 and the water pump 94 can be adjusted according to different coolant temperatures to ensure energy saving and minimum noise.

[0049] Optionally, the condenser tube assembly 3 includes a first tube 31, a second tube 32, and a heat dissipation tube 33. The first tube 31 and the second tube 32 are arranged in parallel and spaced apart within the housing 1. A plurality of heat dissipation tubes 33 are arranged in parallel and spaced apart between the first tube 31 and the second tube 32, and the two ends of the heat dissipation tube 33 are respectively connected to the first tube 31 and the second tube 32.

[0050] In this embodiment, in conjunction with the appendix Figure 3As shown, the first pipe 31 and the second pipe 32 are arranged parallel to each other and spaced apart within the housing 1. A heat dissipation pipe 33 is vertically connected between the first pipe 31 and the second pipe 32, with both ends of the heat dissipation pipe 33 connected to the first pipe 31 and the second pipe 32 respectively. The first pipe 31 and the second pipe 32 can be arranged horizontally, with the first pipe 31 positioned lower than the second pipe 32 within the housing 1. Simultaneously, the heat dissipation pipe 33 is vertically arranged between the first pipe 31 and the second pipe 32. The first pipe 31 can be connected to the first connecting pipe 51, and the second pipe 32 can be connected to the second connecting pipe 52. Coolant can enter from the first pipe 31 and then flow upwards along the heat dissipation pipe 33 to the second pipe 32. The coolant in the second pipe 32 flows from its outlet to the second connecting pipe 52. Because hot air is lighter, allowing the coolant to flow from the bottom (first pipe 31) to the top (second pipe 32) of the condenser assembly 3 improves heat dissipation. Multiple heat dissipation pipes 33 are arranged parallel to and spaced apart between the first pipe 31 and the second pipe 32, that is, there is a gap between any two adjacent heat dissipation pipes 33 to ensure that air can pass through when the fan 2 blows air onto the heat dissipation pipes 33.

Figure 2 (In the X-axis direction), the condenser tube assembly 3 is set close to the first window, and the fan 2 is located on the side of the condenser tube assembly 3 away from the first window, that is, the fan 2 is located between the condenser tube assembly 3 and the second window.
