Description

A portable cooling device for outdoor use

technical field

The utility model belongs to the technical field of outdoor refrigeration equipment, in particular to an outdoor portable cooling device.

Background technique

In recent years, high temperature weather has occurred frequently in many areas in summer, making people who spend a long time outdoors or working suffer from high temperatures. In high temperature weather, along with the evaporation of human sweat, sometimes people will have adverse reactions such as heatstroke. Therefore, in the hot outdoors, how to cool down the human body reasonably and provide a comfortable environment for people has become the focus of people's research.

In order to solve the problem of difficulty in cooling outdoors, small fans that can be worn on the head have appeared on the market, but this small fan is rechargeable and cannot generate continuous power, and its cooling effect is also very limited. It can be seen that if the cooling is to be realized outdoors, the problem to be solved is how to provide enough power for the cooling device so that it can continue to operate and how to improve the cooling effect so that the human body can really feel cool and comfortable. In addition, for portability, it is also very important to reduce the volume of the cooling device.

Solar energy is clean and renewable energy, which is easy to obtain outdoors, which makes solar power generation a more popular outdoor power supply method in recent years. Photovoltaic power generation equipment is usually used in the process of solar power generation. The existing photovoltaic power generation equipment on the market is mainly monocrystalline silicon solar panels, polycrystalline silicon solar panels or thin-film photovoltaic cells, and both monocrystalline silicon solar panels and polycrystalline silicon solar panels have the problems of large volume and heavy weight; considering that outdoor activities or Laborers demand portability, and thin-film photovoltaic cells have become the preferred equipment for outdoor solar power generation due to their advantages of flexibility, bendability, and light weight.

In the research, it was found that the reason why the human body feels hot is actually because the human body is exposed to the sun for a long time, and a large amount of heat is generated after being irradiated by the sun. Therefore, when doing outdoor activities or working, use shelters to avoid sunlight. The human body can alleviate the feeling of heat to a certain extent, but the cooling effect brought by simply blocking the sun is very limited, and usually requires a cooling device to cool down. Most of the commonly used cooling devices are based on evaporative cooling technology. Most of them are direct evaporative cooling technology. Generally speaking, direct evaporative cooling devices are mainly divided into packing direct evaporative cooling devices and direct spray evaporative cooling devices; among them, direct spray evaporative cooling devices can be used as outdoor cooling equipment due to their light size and good cooling effect .
