Problems solved by technology

However, in the known technology, in order to provide the light sources 11 with electric power, it is necessary to use additional wires 14 to connect the light sources 11
In addition, since the light output direction of the light source 11 needs to be adjusted to face the radiator 20 to improve the light output efficiency, the light source 11 must protrude from the inner wall surface of the fan 10 to cause wind resistance, change the flow field of the airflow 13, and reduce the heat dissipation efficiency

Abstract

The invention discloses a radiating unit which comprises a fan, a radiator and a light source, wherein the fan drives an air stream; the radiator comprises a plurality of radiating fins, a light-transmission plate, an air inlet and an air outlet, wherein the radiating fins are arranged in the radiator; the light-transmission plate is arranged on the surface of the radiator; the air stream enters the radiator from the air inlet and flows out from the air outlet; the light source corresponds to the light-transmission plate, wherein the light source provides a light ray which enters into the radiator after passing through the light-transmission plate and leaves the radiator from the air outlet.

Description

technical field [0001] The invention relates to a heat dissipation unit, in particular to a heat dissipation unit with a glare effect. Background technique [0002] refer to figure 1 , which shows a known cooling unit 1 including a fan 10 and a radiator 20 . A plurality of light sources 11 are disposed inside the fan 10 , and the light sources 11 provide light 12 . The light 12 emits from the fan 10 and passes through the heat sink 20 to provide a visual glare effect. At the same time, the fan 10 drives the airflow 13 , and the airflow 13 passes through the radiator 20 to take away the heat on the radiator 20 . However, in the prior art, in order to provide the light sources 11 with electric power, it is necessary to use additional wires 14 to connect the light sources 11 . In addition, since the light output direction of the light source 11 needs to be adjusted to face the heat sink 20 to improve the light output efficiency, the light source 11 must protrude from the in...
