NOVELTY - The utility model claims a sliding groove type touch type circuit board, comprising a bearing plate, the middle of the top part of the bearing plate close to the front and back two ends are fixedly installed with an aluminium alloy heat conducting plate, the top part alloy heat conducting plate is fixedly mounted with graphene radiating layer, the position of the middle of the top of the bearing plate close to the front and back sides is fixedly installed with a radiating fan, the middle of the middle of the left and right ends of the bearing plate close to the lower side is fixedly installed with a connecting plate, the position of the middle of the front end of the bearing plate close to the two sides is provided with a sliding groove. when the circuit board works for a long time, it can turn on the radiating fan, the bottom of the circuit board for air cooling radiating, avoiding the temperature of the circuit board is too high, at the same time, it also can through graphene radiating layer to absorb the temperature of the circuit board, then the absorbed temperature is transmitted to the aluminium alloy heat-conducting plate by graphene radiating layer, The aluminium alloy heat conducting plate has good thermal conductivity, which can effectively lead out the heat and reduce the temperature of the circuit board.
