Description

Laptop external hidden cooling device

The utility model relates to a heat dissipation device used for heat dissipation and ventilation in the general engineering field, in particular to a heat dissipation device combined with an external connection on a notebook computer and hidden in an expansion slot thereof so as to draw in cold air from the outside through a specific direction It is a modular cooling device that sends hot air into the computer or extracts hot air from the inside of the computer for forced cooling. The notebook computer is connected with a hidden cooling device.

It is a known technology to set independent and exclusive cooling devices on the surface of large integrated circuits such as CPUs. At present, whether it is a general personal computer or a notebook computer, the CPU on the motherboard is equipped with an independent cooling device. The main reason is The reason is that the processing speed of the newly developed CPU is increasing day by day, and the operating temperature is also relatively increasing accordingly. In order to ensure its normal operation in an appropriate temperature environment, it is obviously necessary to have a separate cooling device.
