Heat radiating system and method

Abstract

The invention is used in a thermal source and comprises a fan and a dust separating device. The fan is used to generate an air flow from outside; the air flow is blown into the dust separating device to separate the dust from the air flow; after dust separation, the air flow takes the heat from thermal source.

Description

technical field [0001] The invention relates to a heat dissipation system, in particular to a heat dissipation system of an electronic device. Background technique [0002] As the processing speed of electronic devices is getting faster and faster, resulting in an increase in the heat generated during work, if the heat is not properly handled, it will cause a reduction in the processing speed of electronic devices, and even affect the life of electronic devices in severe cases. Therefore, electronic Heat dissipation fins or fans are often installed in the device to help the electronic device dissipate heat. [0003] Since the influence of dust on cooling fins or heat sources has always been regarded as an unavoidable problem in design, designers regard dust as an unpredictable item, and purely reduce the thermal resistance of cooling fins to ensure the design safety factor. But in fact, the accumulation of dust in the air on fins or heat sources will not only affect the the...

AI Technical Summary

Problems solved by technology

However, above-mentioned such existing method basically protects the generation source (ie fan 13) of the airflow, rather than protecting the heat dissipation fins 14 or the heat source 11 as the heat dissipation body

The dust in the air will still accumulate on the cooling fins 12 or the heat source 11, which has no effect on the reliability of the cooling effect and the maintenance of the cooling fins 12.
