[0002] As a core component of modern automotive intelligence and automation, the stability and durability of vehicle computers are crucial for ensuring driving safety and enhancing the driving experience. Traditionally, vehicle computers rely primarily on air-cooling systems to maintain a suitable operating temperature. This mechanism utilizes efficient fans installed on the chassis and carefully designed heat sinks, using the principle of air convection to quickly dissipate heat generated within the computer to the external environment.

[0003] However, in the hot summer, when a vehicle is exposed to high outdoor temperatures, the temperature inside the vehicle can quickly rise to uncomfortable levels. Traditional air cooling methods are unable to effectively dissipate the heat in high-temperature environments. Excessive system temperature not only affects the operational stability of the onboard computer, resulting in reduced processing speed and sluggish response, but may even cause the system to crash or restart. Excessive operating temperature will also accelerate the aging process of internal computer components, shorten their service life, and increase repair and replacement costs. Utility Model Content
