Heat sink and vending machine

Abstract

The invention is applicable to the technical field of heat sinks, and provides a heat dissipating device and a vending machine. The heat dissipating device comprises a fan, a fan motor and a heat dissipating cavity; the fan is connected with the fan motor, and the heat dissipating cavity comprises a first end surface close to the fan and away from the fan. a second end surface; the first end surface and the second end surface further comprise a plurality of sets of heat dissipating copper tubes parallel to the first end surface and disposed in the same direction, and the heat dissipating copper tubes in each set of heat dissipating copper tubes are parallel to each other, and the same group of heat dissipating The copper tube is also covered with a wide gap metal mesh; wherein the fan motor is a positive and negative motor; when the vending machine refrigeration system is started, the fan motor is reversed within a preset time to drive the fan to reverse, so that the heat dissipation cavity is obtained. Wind power from the first end to the second end. The invention can clean the heat sink in time, so that the vending machine refrigeration system can operate stably and efficiently.
