[0002] Currently, devices such as vehicle domain controllers generate heat during operation due to the electrothermal effect of their components. However, the heat dissipation of these devices is relatively poor. Some devices use liquid cooling, which is quite complex. While others use fan convection heat exchange to cool or heat up the device, in scenarios where the device generates a lot of heat or requires rapid heating, the only way to improve heat dissipation is often to increase the fan speed, resulting in high energy consumption. This makes it difficult to balance heat dissipation effectiveness and operating energy consumption in the current technology for vehicle domain controllers and other devices. Utility Model Content

This allows for flexible adjustment of the fan blades' inflow angle while maintaining a relatively small overall size for the drive component and fan, thereby changing the airflow during fan operation and controlling the heat dissipation effect on the component. This method of controlling fan heat exchange does not require continuous high-speed rotation of the fan hub to drive the fan blades in scenarios where the component needs rapid heating or cooling. Instead, it only requires adjusting the fan blades to change the inflow angle to adapt to the heat exchange requirements. The components driving the fan blades relative to the fan hub do not need continuous operation, thus improving fan heat exchange capacity with relatively low energy consumption. It is also suitable for use in scenarios with limited assembly space, such as vehicles, where components need to be centrally located. It is understood that compared to liquid cooling, this solution does not require complex piping structures, resulting in a simpler structure.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0060] According to the first aspect of this application, referring to Figures 1 to 3 As shown, a heat exchange device 100 is provided. In specific applications, the heat exchange device 100 can be used, for example, to dissipate heat or heat a component to be heated in a vehicle 10, wherein the component to be heated is, for example, part of an on-board domain controller, an on-board water tank, or other equipment. The heat exchange device 100 includes a fan 110 for specifically implementing the heat exchange function, and a drive assembly 140 connected to the fan 110.

[0061] The fan 110 includes a hub 120 and fan blades 130. The hub 120 is used to mount the fan blades 130 so that the fan blades 130 can move when in motion, thereby accelerating the flow of surrounding air by the movement of the fan blades 130, which speeds up the heat exchange between the airflow and the heat exchange components, thereby achieving heating or cooling of the heat exchange components.

[0062] The drive assembly 140 is used to drive the fan blade 130 to change the inflow angle. The drive assembly 140 is connected to the fan 110 so that the drive assembly 140 rotates synchronously with the fan 110.

[0063] The fan blade 130 is movably connected to the fan hub 120 so that the inflow angle of the fan blade 130 changes according to the temperature of the heat exchange component when the fan 110 is running. Those skilled in the art will understand that the inflow angle of the fan blade refers to the angle between the fan blade and the airflow direction. In a specific embodiment, for example, the fan blade surface can be configured as a plane, and the inflow angle of the fan blade can be the angle between the airflow direction generated when the fan is operating and the normal to the fan blade surface. As a specific embodiment, the drive assembly 140 is, for example, directly connected to the fan hub 120, so that it rotates synchronously with the fan hub 120 when the fan hub 120 rotates to drive the fan blade 130 to rotate.

[0064] The inflow angle of the fan blade 130 affects the airflow generated during fan operation, thus influencing the fan's efficiency. By changing the inflow angle of the fan blade 130, the fan 110 can adjust the airflow during operation, thereby controlling the heat exchange effect between the airflow and the heat exchange components.

[0065] By adopting the above solution, by configuring the fan blades 130 movably connected on the fan hub 120, during the process of the fan 110 working to heat or cool the component to be heat exchanged, the fan blades 130 can be adjusted relative to the fan hub 120 by the drive component 140 integrated on the fan 110 according to the heat exchange requirements of the component to be heat exchanged. This is beneficial to achieve flexible adjustment of the inflow angle of the fan blades 130 while the overall size of the drive component 140 and the fan 110 is relatively small, thereby changing the airflow when the fan 110 is working and thus controlling the heat dissipation effect of the component to be heat exchanged. This method of controlling the heat exchange effect of fan 110 eliminates the need for continuous high-speed rotation of fan hub 120 and fan blades 130 in scenarios where the component to be heat-exchanged requires rapid heating or cooling. Instead, it simply adjusts the fan blades 130 to change the inflow angle to adapt to the heat exchange demand. Since the components driving the fan blades 130 relative to the fan hub 120 do not need to operate continuously, this method can improve the heat exchange capacity of fan 110 while maintaining relatively low energy consumption. It is also suitable for use in scenarios with limited assembly space, such as vehicles, where components need to be centrally located. It is understood that compared to liquid cooling, this method does not require complex piping structures, resulting in a simpler structure.

[0066] It should be noted that, in practical application, the heat exchange device 100 can be used as part of a heat dissipation module so that the heat dissipation module can achieve the heat dissipation function. By configuring fan blades with adjustable inflow angle, the heat dissipation module can flexibly adjust the heat dissipation effect on external components.

[0067] In practical applications, this application can, for example, integrate a temperature sensor for detecting the temperature of the component to be heat-exchanged on the heat exchange device 100. The temperature parameters detected by the temperature sensor can then be used to control the operation of the components that drive the fan blade 130 relative to the fan hub 120, thereby adjusting the inflow angle of the fan blade 130. The specific electrical connection between the temperature-detecting means, such as the temperature sensor, and the components that drive the fan blade 130 to achieve the control function can be as follows: the temperature sensor can be electrically connected to a control chip to transmit an electrical signal to the control chip. Then, the control chip can control the movement of the fan blade 130 by electrically connecting it to the components that drive the fan blade 130. The specific electrical connection between the temperature-detecting means, such as the temperature sensor, and the components that drive the fan blade 130 to achieve the control function is not the focus of this application. Those skilled in the art can configure it flexibly according to actual needs, and therefore it will not be elaborated here. Furthermore, the temperature sensor is not shown in the accompanying drawings of this application.

[0068] In some embodiments, refer to Figure 2As shown, the drive assembly 140 includes a driven gear 141, a driving gear 142, and a first drive motor 143. The driven gear 141 is connected to the fan blade 130 to drive the fan blade 130 to rotate during rotation, thereby changing the inflow angle of the fan blade 130. The driving gear 142 meshes with the driven gear 141 to drive the driven gear 141 to rotate during rotation. The first drive motor 143 is connected to the driving gear 142 to drive the driving gear 142 to rotate. In a specific embodiment, the first drive motor 143 can be, for example, a motor with a self-locking function, meaning that after the first drive motor 143 stops operating, it can automatically lock the rotor through mechanical or electrical devices to prevent unnecessary movement of the fan blades from affecting the heat exchange effect of the fan 110 on the heat exchange components.

[0069] As an example of the practical application of the above solution, refer to Figure 2 As shown in the specific embodiment illustrated in the attached drawings, a cylindrical transmission shaft 131 is formed on the fan blade 130. The driven gear 141 is a bevel gear coaxially and fixedly connected to the transmission shaft 131. The driving gear 142 is a bevel gear coaxially and fixedly mounted on the output shaft of the first drive motor 143. The driving gear 142 and the driven gear 141 mesh. Thus, when the first drive motor 143 is working, it drives the driving gear 142 to rotate, and the driven gear 141 meshing with the driving gear 142 rotates accordingly, thereby driving the fan blade 130 to rotate relative to the fan hub 120.

[0070] In some embodiments, the fan hub 120 has an inner cavity. This inner cavity is used to accommodate the first drive motor 143, meaning the first drive motor 143 can be fixedly mounted inside the fan hub 120. Furthermore, referring to… Figure 2 As shown, the driven gear 141 and the driving gear 142 are located within the inner cavity, thereby using the fan hub 120 to position and install the first drive motor 143, the driving gear 142, and the driven gear 141. At least a portion of the fan blade 130 is inserted into the inner cavity to connect with the driven gear 141, for example, by inserting the drive shaft 131 on the fan blade 130 from outside the fan hub 120 into the inner cavity, so that when the first drive motor 143 rotates, it can drive the fan blade 130 to rotate relative to the fan hub 120, and when the fan hub 120 rotates, it can drive the fan blade 130 to rotate. This application does not specifically limit the exact position of the inner cavity inside the fan hub 120; those skilled in the art can flexibly configure it according to their needs. The inner cavity is not shown in the accompanying drawings of this application.

[0071] In some embodiments, to achieve rotation of the fan hub 120, refer to Figure 2As shown, the fan 110 also includes a second drive motor 150. The second drive motor 150 is connected to the fan hub 120 to drive the fan hub 120 to rotate around the first rotation axis L1. Thus, when the second drive motor 150 is working, it can drive the fan hub 120 and the fan blades 130 as a whole to rotate around the first rotation axis L1, thereby using the fan blades 130 to accelerate the airflow and enable the airflow to exchange heat with the heat exchange components.

[0072] In some embodiments, refer to Figure 2 As shown, the fan blade 130 is rotatably connected to the fan hub 120 around the second rotation axis L2. For example, the drive assembly 140 is connected to the fan blade 130 to transmit force, thereby driving the fan blade 130 to rotate relative to the fan hub 120 around the second rotation axis L2. In a specific embodiment, under the drive of the first drive motor 143, the fan blade 130 can rotate relative to the fan hub 120 around the second rotation axis. The extension directions of the first rotation axis L1 and the second rotation axis L2 are opposite.

[0073] As an example of the practical application of the above solution, refer to Figure 2 As shown, in the appendix Figure 2 In a specific implementation of the example, the first rotation axis L1 is, for example, the axis of the output shaft of the second drive motor 150, and the second rotation axis L2 is, for example, the axis of the aforementioned transmission shaft 131. The first rotation axis L1 and the second rotation axis L2 are intersecting. In a more specific embodiment, the first rotation axis L1 and the second rotation axis L2 intersect perpendicularly to achieve adjustment of the inflow angle of the fan blade 130.

[0074] Of course, in other specific embodiments, the first rotation axis L1 and the second rotation axis L2 may be configured to intersect at an angle, and this application does not limit this.

[0075] Since the first drive motor 143 is mounted on the fan hub 120, the first drive motor 143 rotates synchronously with the fan hub 120 when the fan hub 120 rotates. A power supply contact can be provided on the fan hub 120. This power supply contact is electrically connected to the first drive motor 143 and is also connected to another contact outside the fan hub 120 that is connected to a power source, so that the power source can supply power to the first drive motor 143 so that the first drive motor 143 can be powered on and work normally.

[0076] In a more specific embodiment, the first rotation axis L1 can be configured to pass through the power supply contact, or the power supply contact can be configured as a ring-shaped contact with the first rotation axis L1 as the axis. The shape of the power supply contact, which is independent of the fan hub 120 and connected to the power supply, is adapted to the shape of the power supply contact, so that when the fan hub 120 rotates, the power supply can supply power to the second drive motor 150 at any time to make the second drive motor 150 work. The power supply contact and the power supply contact independent of the fan hub 120 are not shown in the figure.

[0077] Of course, the above solutions are only some specific examples of the power supply methods for the first drive motor 143. In actual applications, other methods can also be used to power the first drive motor 143, and this application does not limit this.

[0078] In some embodiments, refer to Figure 1 and Figure 3 As shown, the heat exchange device 100 further includes a housing 160. The housing 160 has a receiving cavity 160a for accommodating at least a portion of the component to be heat exchanged, meaning the component to be heat exchanged can be directly integrated inside the heat exchange device 100, thus the housing 160 provides protection for the component. A fan 110 can be fixedly mounted on the housing 160 and located outside the receiving cavity 160a. Therefore, the fan 110 can cool or heat the housing 160 by exchanging heat with it, and the housing 160 further exchanges heat with the component to be heat exchanged, ultimately achieving the goal of cooling or heating the component using the fan 110.

[0079] The housing 160's configuration somewhat limits the heat dissipation of the heat exchange components. In some embodiments, refer to... Figure 1 and Figure 3 As shown, the heat exchange device 100 also includes a heat-conducting plate 170. The heat-conducting plate 170 is made of a material with relatively high thermal conductivity (such as copper, graphite, etc.), and is disposed on the housing 160, and is at least partially located outside the receiving cavity 160a. Taking the use of the heat exchange device 100 to cool the heat exchange component as an example, by setting the heat-conducting plate 170, the heat of the housing 160 is transferred to the heat-conducting plate 170 more quickly, so that the housing 160 and the heat exchange component can exchange heat better.

[0080] In some embodiments, the heat-conducting sheet 170 can be fixed to the housing 160 by means of welding, interference fit, etc., so that the heat-conducting sheet 170 and the housing 160 are in close contact, thereby ensuring the heat transfer effect of the heat-conducting sheet 170.

[0081] In some embodiments, refer to Figure 1 and Figure 3As shown, the heat-conducting plate 170 and the fan 110 are disposed on the same side of the housing 160. Taking the use of the heat exchange device 100 to cool the heat exchange component as an example, the above arrangement allows the fan 110 to be closer to the heat-conducting plate 170, thereby dissipating the heat on the heat-conducting plate 170 into the air more quickly, so that the heat-conducting plate 170 can continuously absorb heat from the housing 160 to ensure the heat dissipation effect of the heat exchange component.

[0082] In a more specific design, multiple heat-conducting plates 170 are positioned around the fan 110. (See reference...) Figure 1 and Figure 3 As shown, in Figure 1 and Figure 3 In the specific implementation of the example, multiple heat-conducting plates 170 are arranged side by side to form a heat-conducting body group. A heat-conducting body group is arranged on both sides of the fan 110. Thus, by setting multiple heat-conducting plates 170, the heat dissipation on the housing 160 is accelerated, and the fan 110 can quickly dissipate heat from each heat-conducting plate 170 on the periphery, so that each heat-conducting plate 170 can stably and continuously absorb heat from the housing 160.

[0083] For the heat exchange components housed in the housing 160, in practical applications, these may be electronic components such as circuit boards. These electronic components often require a relatively dry environment to operate stably, and when the fan 110 accelerates airflow, moisture in the airflow can more easily come into contact with the electronic components. In some embodiments, refer to Figure 3 As shown, the heat exchange device 100 also includes a sealing layer 180. This sealing layer 180 is disposed on the housing 160 to seal the receiving cavity 160a. More specifically, the sealing layer 180 can be disposed between the housing and the heat exchange component located in the receiving cavity. By providing the sealing layer 180, the sealing performance of the receiving cavity 160a can be improved, reducing the possibility of external moisture intruding into the housing 160. This arrangement, when combined with the fan arrangement 100 and other liquid cooling methods for comprehensive heat exchange of the heat exchange component, ensures the stable operation of the heat exchange component located in the housing 160.

[0084] In some embodiments, the sealing layer 180 is configured as conductive adhesive filling the housing 160. While using conductive adhesive to seal the receiving cavity 160a, the conductive adhesive can also provide electromagnetic shielding for electronic components such as circuit boards disposed in the receiving cavity 160a, thereby enabling the electronic components to operate more stably.

[0085] As an exemplary illustration of a specific embodiment in which the housing 160 forms the receiving cavity 160a, the housing 160 includes a first housing portion 161 and a second housing portion 162 that are interconnected.

[0086] The first shell portion 161 and the second shell portion 162 mutually enclose each other to form at least a portion of the receiving cavity 160a, thereby confining at least a portion of the heat exchange component between the first shell portion 161 and the second shell portion 162. A sealing layer 180 may be disposed between the first shell portion 161 and the second shell portion 162 to seal the receiving cavity 160a. More specifically, the first shell portion 161 and the second shell portion 162 are fixed to each other, for example, by means of threaded connection, snap-fit, interference fit, welding, etc., thereby protecting the heat exchange component within the receiving cavity 160a.

[0087] For more specific solutions, refer to Figure 3 As shown, sealing layers 180 can be provided between the first shell portion 161 and the heat exchange component, and between the second shell portion 162 and the heat exchange component.

[0088] According to a second aspect of this application, a vehicle-mounted device is provided, including a component to be heat-exchanged and the aforementioned heat exchange device 100; wherein the component to be heat-exchanged is combined with the heat exchange device 100 to form a heat exchange with the heat exchange device 100. This vehicle-mounted device possesses all the beneficial effects of the aforementioned heat exchange device 100, which will not be elaborated further herein.

[0089] In some embodiments, the vehicle-mounted device is configured as a vehicle-mounted domain controller, meaning that the aforementioned heat exchange device 100 can be specifically applied to heat exchange of at least a portion of the vehicle-mounted domain controller.

[0090] In a more specific embodiment, the component to be heat exchanged is configured as the circuit board 200 of the vehicle domain controller. In a specific embodiment, the circuit board 200 of the vehicle domain controller is, for example, placed in the aforementioned receiving cavity 160a. While the heat exchange device 100 cools down the circuit board 200 of the vehicle domain controller to make it work stably, the housing 160 provides protection for the circuit board 200 of the vehicle domain controller.

[0091] According to the third aspect of this application, referring to Figure 4 As shown, a vehicle 10 is provided, including the heat exchange device 100 described above, or including the on-board equipment described above. The vehicle 10 possesses all the beneficial effects of the heat exchange device 100 or the on-board equipment described above, which will not be elaborated further here.

[0092] The vehicle 10 may be a hybrid vehicle or a new energy vehicle, etc., and this application does not make any specific restrictions on it.
