[0002] The heat dissipation device of the current outdoor projector equipment has a complex structure, a large volume or a low heat dissipation efficiency. For outdoor projection equipment, the volume is too large to be convenient to carry and install, and the poor heat dissipation effect greatly shortens the service life of the equipment. The Chinese utility model patent with application number of fan frame 20 bolts 19 fan 2 peristaltic pump 1844709.4 records an outdoor projector with a circulating heat dissipation structure. The outdoor projector includes a projector body, a shell, an inclined groove, an inclined protruding block, a heat dissipation port, a heat dissipation square tube, a copper tube and a heat dissipation panel assembly. The projector body is installed in the inner cavity of the shell, and is fixed to the shell with four sets of screws through the upper cover plate of the projector body. Secondly, the inclined groove opened at the bottom of the notch of the shell is used to cooperate with the upper inclined protruding block. The temperature in the projector body enters the notch of the inclined groove through the heat dissipation port opened on the inclined protruding block, and is transmitted to the steering tube and the copper tube through the heat dissipation square tube, and the heat dissipation panel assembly connected to the copper tube is used to dissipate the temperature, which is realized through the heat dissipation hole plate.
