[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] See also Figure 1 , Figure 1 Schematic diagram of the overall structure of the heat dissipation assembly provided in an exemplary embodiment of the present disclosure.

[0042] In the first aspect of the present application, a heat dissipation assembly for a sun visor is provided, comprising: a heat conductive member 10 having a receiving surface 11 and a heat conductive surface, wherein the heat conductive surface is used for thermal connection with a display device of the sun visor; a heat dissipation member 20 having a heat exchange cavity 21 and a plurality of openings 22 connected to the heat exchange cavity 21, the heat dissipation member 20 being connected to the receiving surface 11, and the heat exchange cavity 21 being connected to the outside through other openings 22.

[0043] Through the above technical solution, since the three-period minimal surface has a larger specific surface area, the contact area with the air can be increased. The air flows through the surface of the three-period minimal surface heat dissipation structure and removes the heat through convection heat exchange, thereby strengthening the convection heat exchange between the device and the air, improving the heat dissipation performance of the sun visor 70, and ensuring the stability of the display device 50 during long-term operation.

[0044] In the present application, X is the first direction, Y is the second direction, and Z is the third direction.

[0045] Optionally, the outer side wall of the heat sink 20 includes a plurality of heat sink surfaces. This arrangement can maximize the contact area between the heat sink 20 and the outside world, thereby facilitating the improvement of the heat dissipation efficiency of the heat sink 20.

[0046] The outer wall of the heat sink 20 includes at least one three-periodic minimal surface structure 30. In the present application, a minimal surface refers to a surface with an average curvature of zero. The average curvature is defined as the average of any two mutually perpendicular orthogonal curvatures at a point on a spatial surface. If the average curvature of all points on a surface in space is zero, then this surface is called a minimal surface. A three-periodic minimal surface is a minimal surface that is periodic in three directions in three-dimensional space and can be infinitely expanded. This surface structure has a large specific surface area, which can increase the air convection heat exchange area and improve the heat dissipation performance.

[0047] Optionally, the heat dissipation component includes a plurality of heat dissipation members 20, and the plurality of heat dissipation members 20 are arranged in an array along a first direction and a second direction to form a set of heat dissipation units, and the first direction intersects with the second direction. In this application, the first direction and the second direction are perpendicular to each other. By setting the above structure and setting the number of the heat dissipation members 20 to be plural, the contact area between the heat dissipation component and the external air can be increased, which is beneficial to improving the heat dissipation efficiency.

[0048] Optionally, the heat dissipation component includes a plurality of heat dissipation units, and the plurality of heat dissipation units are arranged in sequence along a third direction, and the third direction is perpendicular to the first direction and the second direction.

[0049] Optionally, at least two adjacent heat dissipation members 20 are connected through corresponding openings 22. With such a setting, adjacent heat exchange cavities 21 can also be communicated, facilitating heat exchange with the external air. In this application, all adjacent two heat dissipation members 20 are connected through corresponding openings 22, thus maximizing the heat exchange efficiency between the heat dissipation component and the external air to meet the heat dissipation requirements of the heat dissipation component.

[0050] Optionally, both ends of the heat dissipation member 20 in the first direction respectively have openings 22 and / or both ends of the heat dissipation member 20 in the second direction respectively have openings 22 and / or both ends of the heat dissipation member 20 in the third direction respectively have openings 22. In this application, the openings 22 are symmetrically arranged in the first direction, the second direction, and the third direction. The symmetrical structural arrangement helps to maintain the balance of the force on the heat dissipation member 20, and at the same time, the symmetrical structural design can greatly reduce the difficulty of structural design and processing difficulty. It makes the processing process simpler and more efficient, and is beneficial to reducing the processing cost.

[0051] Optionally, at least two of the openings 22 have different diameters. With such a setting, the heat exchange requirements in different environments can be met, which is beneficial to improving the applicability and application range of the device.

[0052] Optionally, the triply periodic minimal surface includes a P-type triply periodic minimal surface.

[0053] Optionally, the P-type triply periodic minimal surface satisfies the following formula:

[0054] where x, y, and z are the spatial coordinates of the P-type triply periodic minimal surface in the Cartesian coordinate system, and l is the side length of the circumscribed cube of the P-type triply periodic minimal surface.

[0055] Optionally, the heat sink 20 is an integrally formed structure and / or the heat conducting member 10 and the heat sink 20 are integrally formed structures. The integral forming technology combines multiple parts into one heat sink 20 through a single processing or casting process, which significantly reduces the number of parts and assembly time during the manufacturing process. Due to the reduction in the number of parts and assembly time, the integrally formed structure can reduce the manufacturing cost. At the same time, the integrally formed structure makes the heat sink 20 more solid and firm, while reducing the assembly steps and improving the production efficiency. This cost-effectiveness is reflected in multiple industries, such as inductor manufacturing, automotive manufacturing, and construction, etc. The integrally formed structure improves the strength and stability of the structure by integrating multiple parts into a whole. This can ensure the reliability and safety of the heat sink 20 in complex environments.

[0056] Furthermore, the integral forming technology allows for more innovation during the manufacturing process, so that the integrally formed structure can meet the needs of different industries and applications, thus achieving a wider range of applications. And the integrally formed structure can be manufactured using a variety of materials, such as aluminum alloy, copper, stainless steel, etc. These materials have different physical and chemical properties, and appropriate materials can be selected according to specific requirements to manufacture the integrally formed structure.

[0057] Specifically, in automotive manufacturing, the integrally formed structure can adopt new materials and manufacturing processes to reduce energy consumption and environmental pollution.

[0058] In this application, the heat sink 20 can be made of metal materials with high thermal conductivity such as copper or aluminum. The advantages of materials with high thermal conductivity are mainly reflected in the following aspects:

[0059] 1. Rapid heat transfer:

[0060] Thermal conductivity is a key indicator to measure the strength of a material's heat conduction ability. Materials with high thermal conductivity can quickly transfer heat from one end to the other. This efficient heat transfer characteristic is particularly crucial in some high-temperature application scenarios, which can significantly increase the heat transfer speed, thereby improving the heat dissipation efficiency of the heat dissipation component.

[0061] 2. Efficient heat dissipation:

[0062] High thermal conductivity materials can not only quickly transfer heat energy but also dissipate heat efficiently. Taking a heat sink with a high thermal conductivity coefficient as an example, it can export the heat generated by electronic devices faster and more effectively, thereby ensuring that electronic components operate at a stable temperature, improving their operating stability and service life.

[0063] At the same time, since the thermal conductivity of copper is as high as 385 W / m·K (according to some data, the thermal conductivity can even reach about 401 watts / (meter·kelvin)), this means that copper can transfer heat from one area to another very quickly. And the thermal conductivity of copper is uniform, which can transfer heat evenly to the entire heat dissipation surface, avoiding local overheating or overcooling, thus improving the heat dissipation effect of the heat dissipation component. Moreover, copper is a material that is easy to process, so the processing efficiency can be improved.

[0064] Since the thermal conductivity of aluminum is about 205 W / m·K (some data indicates it is 237 W / m·K), this value is higher than that of many other common metals, such as iron and steel. This means that aluminum can transfer heat quickly and effectively, allowing the heat to spread rapidly. The thermal conductivity of aluminum is uniform, which can transfer heat evenly to the entire heat dissipation surface, effectively avoiding local overheating or overcooling, thus improving the heat dissipation effect. Compared with other metals, aluminum is lighter in weight, which enables the overall weight of the heat dissipation component to be reduced.

[0065] As Figures 2 to 4 shown, according to the second aspect of the present application, a sun visor 70 is provided. The sun visor 70 includes a display device 50; the above-mentioned heat dissipation component is arranged in the accommodation cavity, and the heat conducting member 10 of the heat dissipation component is thermally connected to the display device 50.

[0066] In the solution of the present application, a triple-period minimal surface heat dissipation enhancement structure is installed on one side of the key display device 50. A heat dissipation hole 61 is provided at the position of the display device 50. When air flows through the triple-period minimal surface heat dissipation structure, heat is carried away through convective heat transfer to ensure that the display device 50 operates stably within a reasonable temperature range.

[0067] The sun visor 70 integrates waveguide display technology, and the imaging distance of the waveguide display is greater than 10 meters. Passengers can experience large-size high-definition videos more than 10 meters away while sitting in their seats.

[0068] Optionally, a heat conducting member is provided between the heat conducting surface of the heat dissipation component and the display device 50. With this setting, the contact thermal resistance between the two can be reduced, thus facilitating heat conduction between the two and being beneficial to improving the heat dissipation effect of the heat dissipation component on the display device 50.

[0069] Optionally, the heat conducting member includes thermal grease. Thermal grease has extremely high thermal conductivity and can quickly and effectively transfer heat from the heat source to the heat dissipation component, thereby reducing the temperature of the display device 50 and ensuring the stable operation of the display device 50. At the same time, thermal grease, as a high thermal conductivity insulating silicone material, not only has excellent thermal conductivity, but also has good electrical insulation, ensuring that the display device 50 will not be damaged by current leakage during the heat conduction process. In addition, thermal grease can maintain its grease state for a long time in the temperature range of -50°C to +230°C, and can even work in an environment with a high temperature of up to 300°C, meeting the thermal conductivity requirements under various extreme conditions.

[0070] Furthermore, the thermal grease has the characteristics of resistance to high and low temperatures, water, ozone, and weather aging, stable chemical and physical properties, and reliable long-term use effect, thus being able to meet the use requirements of the device.

[0071] Optionally, the sun visor 70 further includes a plate body 40 and a cover body 60 , wherein the cover body 60 is covered on the plate body 40 and together with the plate body 40 forms a receiving cavity, and the display device 50 and the heat dissipation assembly are disposed in the receiving cavity.

[0072] Optionally, the cover 60 is provided with a heat dissipation hole 61 connected to the accommodating cavity, and the heat dissipation hole 61 is provided corresponding to the heat dissipation component. In this way, the heat generated by the display device 50 is transferred to the three-period minimal curved surface heat dissipation structure through heat conduction, and the air flows over the surface of the three-period minimal curved surface and removes the heat through convection heat exchange.

[0073] Optionally, there are multiple heat dissipation holes 61, and the multiple heat dissipation holes 61 are arranged in an array on the cover body 60. This arrangement can increase the heat exchange flow between the accommodating cavity and the external air as much as possible, thereby improving the heat dissipation effect of the heat dissipation component.

[0074] According to a third aspect of the present application, a vehicle is also provided, comprising the sun visor 70 as described above.

[0075] In the heat dissipation assembly for the sun visor projector of the embodiment of the present application, the heat dissipation assembly for the sun visor projector. Through the above technical solution, since the three-period minimal surface has a large specific surface area, the contact area with the air can be increased, and the air flows through the surface of the three-period minimal surface heat dissipation structure and removes heat through convection heat exchange, thereby strengthening the convection heat exchange between the device and the air, improving the heat dissipation performance of the sun visor 70, and ensuring the stability of the display device 50 during long-term operation.
