Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted cooling, and more specifically, to a vehicle-mounted cooling structure. Background Art

[0002] In the hot summer, especially in the sunny southern region, the temperature inside the car often rises sharply, causing discomfort to passengers and drivers. The traditional cooling method mainly relies on the car air conditioning system. However, in a high temperature environment, even if the air conditioning is turned on at the highest level, it is difficult to quickly reduce the temperature inside the car. An important reason for this is that part of the sunlight directly shines into the interior of the car through the external sheet metal protection cover of the vehicle (such as the engine protection cover, roof, front and rear doors, etc.), causing the temperature inside the car to rise;

[0003] Although the traditional vehicle air conditioning system can effectively reduce the temperature inside the car, it will consume a lot of fuel if it runs for a long time, increasing driving costs. It will also produce additional exhaust emissions, which will have an adverse impact on the environment. In addition, the air conditioning system's consumption of vehicle power cannot be ignored, especially when the vehicle is stationary or driving at low speed, the power consumption will be more significant. Therefore, we have made improvements to this and proposed a vehicle cooling structure.

[0004] For example, a Chinese patent (publication number CN109878293B) discloses an automatic cooling device, method and car for a car, and its specification discloses: With the development of society, more and more cars have entered ordinary families. At the same time, global warming has caused the temperature inside the car to be too high in summer, and this phenomenon has seriously affected people's travel experience. Due to the sun's exposure, the interior of the car not only increases in temperature, but also produces various plastic odors, which seriously affect people's health. What is particularly serious is that many parents reported on the Internet that when they drove their children out, they accidentally left their children in the car, and the high temperature in the car caused accidents to the children. Therefore, there is an urgent need for a device that can save costs and automatically help cool down the interior of the car. The above patents can prove the defects of the existing technology.
