Description

External high-efficient heat sink of computer host Technical Field The invention belongs to the technical field of computer auxiliary equipment, and particularly relates to an external efficient cooling device of a computer host. Background When the desktop computer host runs for a long time under high load, the internal CPU, the display card and other parts of the desktop computer host can generate a large amount of heat. If the heat dissipation is poor, the internal temperature of the host is too high, so that the system is blocked, a blue screen and even hardware are damaged. The traditional heat dissipation mode mainly depends on a fan in a case, but the problems of unsmooth internal air channel or insufficient heat dissipation capability are particularly remarkable for some old machine types, small-sized cases or high-power consumption hosts. Most of the existing hosts are directly placed on a desktop or a common base, the existing hosts are easy to fall down due to collision, the problem that the existing hosts are difficult to move is solved, the built-in fans are limited by the inner space of a case, air circulation is not smooth, heat dissipation dead angles are caused, and hardware frequency reduction is easy to occur in a high-temperature environment. In order to prevent dust from entering the case, the air inlet of the main machine is usually provided with a filter screen, but the filter screen is required to be manually disassembled for cleaning after dust accumulation, so that the operation is complicated, if the dust is not cleaned for a long time, the air inlet quantity is reduced, the heat dissipation efficiency is greatly reduced, and when the filter screen is manually cleaned, the dust is easily scattered to the tabletop or the inside of the case, so that secondary pollution is caused, and the indoor environment and the cleanliness of hardware are influenced.
