[0002] In hot summer days, sunshade tents are commonly used equipment for people during outdoor activities, which can provide people with a shady temporary rest area. Sunshade tents generally have a foldable structure. Although sunshade tents can block the heat brought by direct sunlight, due to the high surface temperature in summer, people still feel unbearably stuffy under the sunshade tent in a windless environment.

[0003] In order to further reduce the temperature under the sunshade tent, people usually use external devices for auxiliary cooling, such as high-pressure spray devices, outdoor air conditioners, etc. Although the cooling effect is good, their drawbacks are also obvious: high-pressure spray devices will cause the environment to be humid and will wet people's clothes; outdoor air conditioners have problems such as high power consumption, being bulky, and being limited by external power sources. They have certain requirements for the use environment and are not convenient to use. Summary of the Utility Model:

[0007] A concave pit is provided in the middle of the upper surface of the housing; a filter screen is provided at the air inlet for filtering sand and gravel. The filter screen blocks dust and other impurities from entering the interior of the housing, protecting the cleanliness and efficient operation of the interior of the cooling fan.

[0008] The outer shape of the housing is cylindrical; the water-absorbing cooling cylinder is a circular cylinder; the annular spray pipe is a circular ring pipe; both the air inlet and the air outlet are vertical strip-shaped openings, and the air outlet through holes are arranged on the upper surface of the air outlet hood; the concave pit is a square concave pit.

[0009] The M water spraying through holes are evenly distributed on the lower surface of the annular spray pipe; the N water leakage through holes are evenly distributed on the surface of the transverse partition.

P is a natural number greater than or equal to 3. The air cooler can be firmly fixed to the ground by driving nails or other means through the fixing installation through holes.

[0012] The function of the cross-flow fan is to suck in the air at the air inlet and discharge it from the air outlet. The front windshield and the rear windshield can prevent the cooled air from flowing back to the air inlet. The symmetrical design of the air inlet and the air outlet ensures the smooth flow of air inside the housing and optimizes the evaporation cooling effect. The lower cavity is used to store water. The circulation water pump extracts water from the lower cavity and transports it to the annular spray pipe. The valve is used to control the flow of water and can be opened or closed as needed. The function of the annular spray pipe is to evenly spray water onto the water-absorbing and cooling cylinder, realizing the even distribution and effective utilization of water. The water leakage through holes on the transverse partition plate can enable the excess water in the upper cavity to flow back to the lower cavity.

[0013] A sunshade tent that uses solar energy to generate electricity and refrigerate and contains the above air cooler includes a tent body. The tent body is propped up by T support rods at its lower part. A photovoltaic power generation panel is installed on the top of the tent body. The air cooler is arranged below the support rods. The lower end of the support rod is inserted into the concave pit on the upper surface of the air cooler housing. The shape and size of the lower end of the support rod match the shape and size of the concave pit. An air outlet pipe is fixed along the support rod. The lower end of the air outlet pipe is communicated with the air outlet through hole of the air cooler, and the upper end of the air outlet pipe extends to the top inside the tent body. The photovoltaic power generation panel supplies power to the cross-flow fan and the circulation water pump of the air cooler through a cable, enabling the air cooler to operate and continuously output cold air even in an environment without an external power grid. T is a natural number greater than or equal to 1.

[0014] T is a natural number greater than or equal to 3. T air coolers are respectively arranged below T support rods. The upper ends of the T support rods are connected to the T corners of the tent body. T photovoltaic power generation panels are respectively arranged at the upper ends of the T support rods.

[0015] Each support rod is provided with two bifurcations at its upper end. The tent body is installed on the inner bifurcation, and the support feet of the photovoltaic power generation panel are installed on the outer bifurcation.

[0016] The photovoltaic power generation panel is connected to the support feet through a rotary joint. The support feet are of a hollow structure and are inserted into the outer bifurcation. The tent body is a sunshade cloth, the concave pit is a square concave pit, and the support rod is a square rod.

[0017] The cable is semi-embedded in the groove on the side wall of the support rod, reducing the risk of damage to the cable in the external environment and also avoiding the cable being exposed in a messy manner, which affects the operation and visual experience of the user.

[0018] When using this sunshade tent, first unfold the tent, then insert the support rod into the pit on the upper surface of the air cooler. Next, fix the air outlet pipe and install the photovoltaic power generation panel.

[0019] The main function of the air cooler is to draw in external air through evaporation cooling technology, cool and humidify it, and then discharge the processed cold air from the air outlet. The cold air discharged by the air cooler is transported to the inside of the tent through the air outlet pipe to reduce the local temperature inside the tent. The air cooler adopts direct evaporation cooling technology (DEC), and its working principle is: when air comes into direct contact with water on a large area, the evaporation of water will cause the temperature of the air to drop, and at the same time, the moisture content of the air will increase, converting the sensible heat of the air into latent heat.

[0020] The air cooler is detachable from the support rod, which not only facilitates the storage of the tent but also makes it convenient for carrying and transportation. The height and air outlet direction of the upper end of the air outlet pipe can be adjusted according to actual usage requirements, making it easy to use. The photovoltaic power generation panel can be flexibly adjusted in direction and angle through a rotating joint to optimize the power generation efficiency.

[0021] The projection of the annular spray pipe in the vertical direction coincides with the projection of the water absorption and cooling cylinder in the vertical direction, so that water can be evenly sprayed onto the water absorption and cooling cylinder, thereby achieving the best evaporation cooling effect when air flows through the water absorption and cooling cylinder and ensuring the stable operation of the air cooler. When the outside air enters the housing from the air inlet under the action of the cross-flow fan, the air will pass through the side wall of the water absorption and cooling cylinder twice, experiencing two evaporation cooling processes, thus significantly enhancing the refrigeration efficiency of evaporation cooling.

[0022] The beneficial effects of the present utility model are as follows:

[0023] 1. According to the evaporation cooling principle, the air cooler of the present utility model uses a cross-flow fan to draw in external air into the housing, cools and humidifies it through the water absorption and cooling cylinder, and then discharges the processed cold air from the air outlet, and then transports it to the sunshade tent through the air outlet pipe to reduce the temperature inside the sunshade tent. Compared with the prior art, the present utility model not only avoids using a high-energy-consuming compressor, has low energy consumption, saves electric energy, but also avoids the common fogging and water droplet splashing of high-pressure spray type sunshade tents, has a good refrigeration effect, makes people feel more comfortable, and creates a cooler and more comfortable space in a hot outdoor environment.

[0024] 2. The sunshade tent of the present utility model converts light energy into electrical energy through the photovoltaic power generation panel on the top of the tent body, which is used to supply the cross-flow fan and circulating water pump of the air cooler, and can also refrigerate without an external power supply, making it convenient to use and highly environmentally friendly.

[0025] 3. The lower end of the support rod of the sunshade tent of the present utility model is inserted into the concave pit on the upper surface of the air cooler, and the support feet of the photovoltaic power generation panel are inserted into the upper fork of the support rod. This structure is convenient for assembly and disassembly and is more suitable for the temporary outdoor use of the sunshade tent.

[0026] 4. The humid air in the air outlet pipe of the sunshade tent of the present utility model will condense into water droplets on the pipe wall. These water droplets will flow down along the air outlet pipe and into the upper cavity of the air cooler. Then, they will flow into the lower cavity through the water leakage through holes on the transverse partition, realizing the recycling and utilization of water resources, which is energy-saving and environmentally friendly.
