What is the Principle of Cooling Spray?
2 Answers
Automotive cooling spray is a formulation that can rapidly lower the temperature inside a vehicle. Its main ingredients include dry ice, softened water, and a small amount of fragrance. Below is an introduction to automotive cooling spray: 1. It can generally be sprayed on surfaces inside the car, such as seats and the dashboard. Upon contact with heat, it quickly vaporizes, absorbing surface heat. It is suitable for cooling car interiors, reducing overheating of brake pads during off-road trips, rapid cooling during repairs of exhaust pipes, quick ice-making, and indoor cooling in various high-temperature environments. It can also be used in emergency rescue scenarios like firefighting. 2. Simply spray lightly on seats or any part of the car interior, and the temperature inside the vehicle will drop instantly. "Instant Cool" (rapid car interior cooling spray) is the latest product developed using advanced foreign technology and equipment for cooling car air and seats. With its unique formula and noticeable effects, it can instantly lower the temperature by 40 degrees.
I remember being quite puzzled when I first heard about coolant, but later when I started driving, I realized it's simply the car's cooling liquid, and its working principle is quite straightforward. When the engine runs, it generates heat, and the coolant is pumped by the water pump to circulate around the engine, absorbing the heat and becoming hot. Then it flows to the radiator at the front of the car, where the fan blows or the airflow dissipates the heat. The cooled liquid then returns to absorb heat again, creating a continuous cycle. It also contains ethylene glycol, which prevents freezing in winter and withstands high temperatures without boiling in summer. Before every long trip, I check the fluid level and add some distilled water to maintain it, preventing the engine from overheating. Once in the summer, I neglected this, and the engine almost overheated. Since then, I've developed a habit of regular replacement, about every two years, to prevent system corrosion or clogging, ensuring the car's longevity.
