Heat dissipation device of heat dissipation fan in computer case

Back to list Release date: Jul 30, 2019

In order to increase the heat dissipation performance of the computer chassis, a heat dissipation fan is generally fixedly arranged on the inner side of the back plate of the existing computer chassis, and a ventilation area formed by densely distributed ventilation holes is arranged at the position of the back plate opposite to the heat dissipation fan, and the area of the ventilation area is equivalent to that of the heat dissipation fan. On the other hand, the CPU heat sink is generally installed at the inner side of the side plate of the computer case, and a heat dissipation fan is fixedly installed at the other side of the CPU heat sink.However, due to the limited space in the computer case and many other components, there is a great resistance to ventilation and heat dissipation, and in order to improve the heat dissipation efficiency, the rotation speed of the heat dissipation fan must be increased, which will lead to an increase in the noise of the heat dissipation fan.

The invention relates to a heat dissipation device of a heat dissipation fan in a computer case.A heat dissipation fan is fixedly arranged on the back plate of the case, a plurality of ventilation holes are arranged on the back plate of the case opposite to the heat dissipation fan, CPU radiating fins are arranged on the inner side of a side plate of the computer case, a diversion pipeline is connected between the heat dissipation fan and the CPU radiating fins, and two ends of the diversion pipeline respectively cover the heat dissipation fan and the CPU radiating fins. The scheme can improve the heat dissipation efficiency of the fan in the computer case and shield the noise generated by the heat dissipation fan.
