Description

A notebook computer hybrid radiator

technical field

The utility model relates to the technical field of computer accessories, in particular to a hybrid radiator for notebook computers.

Background technique

At present, the heat dissipation method of existing computers is mainly air-cooled. The main method is to quickly spread the heat generated by the heat source into the chassis by setting a heat sink at the heat source, and then accelerate the air convection through the exhaust fan arranged on the chassis to dissipate the heat. Quickly and timely discharge the chassis; but this cooling system has the following defects: 1. Although the fast air flow speeds up the cooling speed, it also produces a lot of noise, which affects the comfort of use; 2. Long-term and rapid air convection will bring a large amount of dust into the chassis and adhere to the equipment and cables, which will not only affect the stability of equipment operation, but also block the cooling holes and reduce the cooling effect; 3. The cooling method is single , when it is in summer, the temperature of the air is high, and the temperature difference with the equipment is small. Even if the air circulation is smooth, the heat dissipation effect is relatively poor; high computer.
