Why are car refrigerant pipes not wrapped?

[SanLucia]

Car refrigerant pipes are not wrapped because they need heat dissipation. The functions of an air filter include the following 3 points: 1. Provide fresh air: It prevents the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the cabin, preventing passengers from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: It keeps the cabin air clean and free from bacterial growth, effectively separating solid impurities such as dust, core powder, and grinding particles from the air; it effectively blocks pollen, ensuring that passengers do not experience allergic reactions that could affect driving safety. 3. Adsorb harmful substances: It adsorbs moisture, soot, ozone, and odors from the air, with strong and durable moisture adsorption capabilities.
