The invention relates to a tunnel air-cooled power supply based on an insulation heat conduction pad. The tunnel air-cooled power supply comprises a box body and a power supply main body. The box bodyis divided into an upper cavity and a lower cavity through a separator plate. The upper cavity of the box body is provided with a run-through tunnel air channel. The lower cavity of the box body is in an enclosed structure. The power supply main body is arranged in the lower cavity of the box body. A first heat conductive member is arranged between the power supply main body and the separator plate. The first heat conductive member is a flexible insulation heat conduction pad. The tunnel air-cooled power supply has the advantages of being simple in structure, low in cost, safe and reliable and good in heat dissipation, and can effectively ensure work stability and reliability.
Description
technical field [0001] The invention relates to a power supply, in particular to a high-power, high-density air-cooled power supply based on an insulating thermal pad. Background technique [0002] In some special fields, it is required that the high-power power supply should have the characteristics of miniaturization and excellent electromagnetic compatibility to meet the application requirements in harsh environments. For this reason, this type of high-power power supply mostly adopts a closed chassis and achieves the above-mentioned purpose by densely distributing power devices. However, in practical applications, due to the fact that power supply products are heat-generating devices under working conditions, and due to the closedness of the power supply chassis and the high density of power devices, existing high-power power supplies often cause excessive internal temperature due to poor heat dissipation, which not only affects The stability and reliability of its work...
