It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0035] This embodiment provides a vehicle, including a vehicle body and a roof tent, wherein the roof tent is installed on the top of the vehicle body. Figure 1 and Figure 2As shown, the roof tent includes a tent body 200 and a solar module 100. The solar module 100 is arranged on the outer wall of the tent body 200. The solar module 100 can convert solar energy into electrical energy required by the user, thereby meeting outdoor electricity needs.

[0036] Further, such as Figure 2-Figure 5 As shown, the solar module 100 includes a solar panel 1 and a heat sink 2. The heat sink 2 is arranged on the back side of the solar panel 1. The heat sink 2 is attached to the back of the solar panel 1. The heat sink 2 has or contains a heat-conducting medium. The heat-conducting medium can absorb the heat generated by the solar panel 1 and dissipate it outward through phase change.

[0037] Specifically, the rooftop tent provided in this embodiment addresses the user's outdoor electricity needs by installing a solar module 100 on the tent body 200. Furthermore, a heat sink 2 is provided on the back side of the solar panel 1. The heat-conducting medium in the heat sink 2 directly absorbs the heat generated by the solar panel 1 and dissipates the heat outward through a phase change of the heat-conducting medium, thereby cooling the solar panel 1 and improving the power generation efficiency of the solar panel 1, thereby increasing the utilization rate of solar energy. Furthermore, the operating time of the solar panel 1 at high temperatures is reduced, slowing the aging rate of the solar panel 1 and extending its service life.

[0038] In this embodiment, the heat sink 2 is a hydrogel, and the thermal conductive medium is water. Hydrogel is a general term for polymers with a high water content and specific shapes and mechanical properties. The specific heat capacity and thermal conductivity of hydrogel are comparable to those of water, approximately 4.2-5.2 kJ / (kg*K). When heated, the hydrogel reaches its dehydration point and loses a large amount of water. Once the temperature drops, it absorbs water molecules from the air, returning to its original state. This water absorption and dehydration process is entirely a passive physical property, with no active energy consumption. When the solar panel 1 is idle, the hydrogel absorbs moisture from the air. When the solar panel 1 is operating, the hydrogel absorbs heat dissipated by the solar panel 1. Simultaneously, the water within the hydrogel evaporates under the influence of high temperature and sunlight, removing a large amount of heat during the evaporation process. This heat dissipation method is not only highly efficient, but also requires no additional energy to drive the heat dissipation. Compared to air cooling, it also produces less noise pollution, thus embracing environmental protection and energy conservation. Furthermore, hydrogel has excellent biocompatibility and stability, is harmless to the human body, and is well-suited for use in outdoor products.

[0039] Exemplarily, the hydrogel's water loss point is set at 40°C to 50°C. Preferably, the hydrogel's water loss point is set at 45°C. A control experiment was conducted to test the actual temperature control and power generation efficiency improvement effects of the hydrogel with a water loss point of 45°C on the solar panel 1. The test conditions were a fixed angle between the solar panel 1 and the ground, and the test lasted for 6 hours. The control group consisted of solar panels 100 without a cooling structure. The test results are shown in Table 1.

[0040] Table 1:

[0041]

[0042] It can be seen that under different ambient temperatures, the hydrogel can effectively reduce the surface temperature of the solar panel 1. Compared with the control group, the surface temperature of the solar panel 1 using the hydrogel group is reduced by about 20°C, and the power generation efficiency of the solar panel 1 is increased by 7%-10%, which is a significant effect. Especially when the ambient temperature is 35°C, the power generation efficiency of the solar panel 1 is increased by about 10%.

[0043] In other embodiments of the present invention, the heat sink 2 may also be a heat pipe. The heat pipe is filled with a liquid heat-conducting medium. When a heat source heats the heat-conducting medium, the medium evaporates into gas, removing heat. The gas then condenses into liquid in the condensation section of the heat pipe, releasing heat and flowing back to the evaporation section, forming a closed-loop heat dissipation system.

[0044] For example, the outer periphery of the heat sink 2 is covered with a waterproof and dustproof membrane, which seals the heat sink 2 therein and effectively prevents liquid water and dust from passing through. The waterproof and dustproof membrane can be made of a microporous membrane such as PTFE (polytetrafluoroethylene), Nylon (nylon), PES (polyethersulfone), PVDF (polyvinylidene fluoride), PP (polypropylene), NC (nitrocellulose), or MCE (microporous cellulose ester).

[0045] For example, Figure 2-Figure 5 As shown, the solar assembly 100 further includes a support plate 3 , which is used to fix the solar panel 1 and the heat sink 2 . The support plate 3 is located on the side of the heat sink 2 facing away from the solar panel 1 , and is mounted on the outer wall of the tent body 200 .

[0046] For example, Figure 5 As shown, the heat sink 2 and the support plate 3 are spaced apart to form a heat exchange gap 10 between the heat sink 2 and the support plate 3. The heat exchange gap 10 allows the heat-conducting medium to fully exchange heat with the air, releasing heat from the heat sink 2. Specifically, the liquid water in the hydrogel evaporates and then passes through the waterproof and dustproof membrane to dissipate into the heat exchange gap 10.

[0047] For example, Figure 2-Figure 5As shown, the solar panel 100 further includes a fixing frame 4, which is mounted on the support plate 3. The solar panel 1 is mounted on the side of the fixing frame 4 facing away from the support plate 3. The fixing frame 4 is provided with a hollow portion 41, and the heat sink 2 is mounted in the hollow portion 41. Specifically, the heat sink 2 is located in the hollow portion 41 and is connected to the solar panel 1 or the fixing frame 4 by screws. The solar panel 1 is mounted to the fixing frame 4 by screws to keep the heat sink 2 in close contact with the back of the solar panel 1, thereby ensuring the heat transfer efficiency of the solar panel 1 to the heat sink 2.

[0048] For example, Figure 2-Figure 5 As shown, the solar module 100 includes at least two heat sinks 2, which are arranged side by side. The fixing frame 4 also has at least two corresponding hollow portions 41. In this embodiment, there are three heat sinks 2, and three corresponding hollow portions 41. The three heat sinks 2 are spaced apart along the length of the solar module 100. The three heat sinks 2 collectively absorb heat emitted by the solar panel 1, thereby enhancing the heat dissipation effect.

[0049] For example, Figure 3-Figure 5 As shown, a receiving groove 31 is provided on the support plate 3, and the fixing frame 4 is mounted in the receiving groove 31. A heat exchange gap 10 is formed between the fixing frame 4 and the bottom of the receiving groove 31. The lateral dimension of the fixing frame 4 is smaller than that of the receiving groove 31. This not only facilitates the assembly of the fixing frame 4, but more importantly, it also forms a ventilation gap 20 between the edge of the fixing frame 4 and the sidewall of the receiving groove 31. The ventilation gap 20 is connected to the heat exchange gap 10. Specifically, the provision of the ventilation gap 20 connects the heat exchange gap 10 with the external atmosphere, allowing the evaporated water vapor in the hydrogel to dissipate quickly, thereby improving the heat exchange efficiency between the solar module 100 and the external atmosphere.

[0050] For example, Figure 4 and Figure 5 As shown, the length of the fixing frame 4 is smaller than the length of the accommodating groove 31, and ventilation gaps 20 are formed at both ends of the accommodating groove 31 in the length direction. The two ventilation gaps 20 and the heat exchange gap 10 therebetween constitute a heat exchange channel structure, which can accelerate the flow rate of air and increase the speed at which water vapor is carried away by the air, thereby further improving the heat exchange efficiency between the solar module 100 and the external atmosphere.

[0051] Exemplarily, the support plate 3 is made of metal materials such as aluminum alloy, which has the advantages of being light, strong and having good thermal conductivity.

[0052] Exemplarily, the fixing frame 4 is made of metal materials such as aluminum alloy, which has the advantages of being light, strong and having good thermal conductivity.

[0053] For example, Figure 2-Figure 5As shown, the solar panel 100 further includes a thermal insulator 5, which is disposed on the side of the support plate 3 facing away from the heat sink 2. The thermal insulator 5 is secured to the back side of the support plate 3 via screws, clips, or other structures. The thermal insulator 5 extends over the entire area of ​​the receiving groove 31, effectively preventing heat from the solar panel 1 and the heat sink 2 from being transferred into the interior of the tent body 200 and reducing the impact on the internal temperature of the tent body 200. The thermal insulator 5 and the heat sink 2 together constitute the temperature control system of the solar panel 100, both lowering the temperature of the solar panel 1 and reducing the transfer of heat from the solar panel 1 to the tent body 200.

[0054] Exemplarily, the heat insulating member 5 is heat insulating cotton, preferably polyurethane heat insulating cotton. Of course, the heat insulating member 5 can also be made of other heat insulating materials such as aerogel.

[0055] For example, Figure 1 and Figure 2 As shown, the roof tent further includes a ladder 210 , which is connected to the opening of the tent body 200 . The ladder 210 is configured as a foldable and detachable soft ladder structure, so that the user can easily fold and store the ladder 210 .

[0056] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
