Of course it is necessary. In summer, using a car sunshield will have the following benefits:

1. Reduce the temperature inside the car. The sunscreen is composed of multiple layers of bubble film and aluminum foil. It belongs to a kind of plastic product. The bubble film has good strength, toughness, and impact resistance, while aluminum foil has the ability to reflect light. , so as to reduce thermal radiation, and has low thermal radiation conduction ability, when the sun shines on the sunshade, part of the heat will be blocked, and the ultraviolet rays will be reflected by the aluminum foil;

2. Protect the instrumentation equipment in the car. Direct exposure to sunlight will make the temperature in the car up to about 70 degrees. Not only is the center console shell easily deformed, but the instruments on the instrument panel and audio equipment are also damaged due to high temperature, such as components. Aging, pin de-soldering, etc., the sunshade can effectively avoid direct sunlight;

3. Reduce pollution in the car. The center console and interior of the car are generally made of plastic. Long-term high temperature will cause them to emit harmful substances and affect human health. The use of sunshade can make the car The internal temperature has dropped.
