Problems solved by technology

[0002] With the improvement of people's living standards, cars have become more and more common means of transportation, and car covers are one of the most important parts of cars, including car roof covers, car engine covers, car tail covers, etc. Because the profile used in the car cover is a good conductor of heat, in the face of high temperature environments such as the summer heat, good thermal conductivity often makes passengers feel uncomfortable. At the same time, excessive temperature can easily cause accidents and cause losses.
