Abstract

The invention discloses a power supply power device radiation structure which comprises a radiator and at least one power magnetic device. The radiator comprises a top plate and two side plates; the top plate and the two side plates form a U-shaped structure; the open slot formed by the top plate and the side plates is a power magnetic device installation slot; the power magnetic device is arranged in the open slot and radiates through the top plate and the side plates. Because the single-side radiation of the power magnetic device is changed into multiple-side radiation, the radiating efficiency of the power magnetic device is improved, and because the power magnetic device is arranged in the open slot of the radiator, the anti-seismic effect of the power magnetic device can be improved. The power supply power device radiation structure is particularly suitable for the automobile power supply.

Description

[technical field] [0001] The invention relates to a heat dissipation structure of a device, in particular to a heat dissipation structure of a power device. [Background technique] [0002] The small power devices in the traditional power supply series flat package, such as semiconductor power devices, power resistors, etc., and power magnetic devices, such as transformers, inductors, etc., use the main heat dissipation surface of these power devices to dissipate heat on one side, and use screws to pass through the power The fixing holes on the device, or the use of pressure strips to press the main heat dissipation surface of the power device and the heat dissipation surface of the radiator to conduct heat conduction. The disadvantage of this heat dissipation method is that the installation process is complicated, there are many auxiliary materials such as beading and screws, and the cost is relatively high; the power device dissipates heat on one side, and the heat dissipat...
