Problems solved by technology
[0002] In some complex environments, such as factory buildings and farmland with poor ventilation, the heat generated by the electrical components in the distribution box cannot be completely removed. If the temperature is too high, it will easily lead to unstable operation of the electrical components and even dangers such as burning.
[0003] Traditional power distribution boxes use fans for forced airflow to dissipate heat, which can easily bring dust from the outside into the power distribution box, causing circuit breakage of related electrical components.

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.
Description
technical field [0001] The invention relates to a heat dissipation mechanism of a distribution box, which belongs to the field of electric engineering. Background technique [0002] In some complex environments, such as factory buildings and farmland with poor ventilation, the heat generated by the electrical components in the distribution box cannot be completely removed. If the temperature is too high, it will easily lead to unstable operation of the electrical components, and even dangers such as burning. [0003] However, traditional distribution boxes use fans for forced airflow to dissipate heat. It is easy to bring dust from the outside into the distribution box, causing circuit breakage of related electrical components. Contents of the invention [0004] The invention provides a heat dissipation mechanism capable of dissipating heat from electrical components and surroundings. [0005] The technical solution adopted by the present invention to solve its technical ...
