Abstract

The invention relates to a heat radiation mechanism of a distribution box. The heat radiation mechanism comprises a heat conduction sleeve which penetrates through two end wall surfaces of the distribution box. A heat collecting sleeve sleeves the heat conduction sleeve. The heat collecting sleeve is connected with the heat conduction sleeve in a heat-conductive manner. The heat collecting sleeve is provided with a plurality of annular welding troughs for embedding capillary heat tubes. A plurality of capillary heat tubes are embedded into the welding troughs. The distribution box is internally provided with a plurality of heat-conductive boards which closely abut against the inner part of the electronic component housing. The heat-conductive boards are connected with the capillary heat tubes in a heat-conductive manner. Two axial ends of the heat conduction sleeve are provided with axial flow fans in correspondence with outer part of the wall surface of the distribution box. According to the heat radiation mechanism, heat radiation is performed through a capillary heat tube heat conduction mechanism which is arranged in the distribution box and one copper heat conduction sleeve; and an air channel in the heat conduction sleeve is directly isolated from the distribution box, thereby preventing a trouble caused by dust.
