Heat dissipation device and coal quality detection device

The invention relates to the technical field of heat dissipation of coal quality detection equipment, and discloses a heat dissipation device and a coal quality detection device.The heat dissipation device comprises a dustproof mechanism and a heat dissipation mechanism. The heat dissipation mechanism is in a closed state, meanwhile, power is provided to enable heat in the body to be dissipated from the heat dissipation holes, and in the heat dissipation process, the dustproof mechanism prevents dust outside the body from entering the body from the heat dissipation holes. After the dustproof mechanism is used for a period of time, dust is accumulated on the dustproof mechanism, the dustproof mechanism needs to be cleaned, at the moment, the heat dissipation mechanism is switched from the closed state to the open state, the dustproof mechanism is exposed, and the dust on the dustproof mechanism is cleaned, so that the dustproof mechanism is not blocked by the heat dissipation mechanism any more; the cleaning e
