Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a bull electromagnetism stove heat radiation structure, its includes end box 1 and covers panel 2 at its upper end, its characterized in that: end box 1 coat and have baffle 3, form down wind channel 4 between baffle 3 and the end box 1, form wind channel 5 on the baffle 3 and the panel 2 between, the ventilation hole 6 has been seted up on the baffle 3 to install ventilating fan 7 in ventilation hole 6, the wind channel switches on about ventilating fan 7 will, lower wind channel 4 in install main control circuit board 8, go up wind channel 5 in install high frequency coil panel 9, lower wind channel 4 switches on with lower vent 15 that sets up on end box 1, last wind channel 5 switches on with last vent 11 on the panel 2.
The bottom box 1 is provided with a plurality of upward extending isolation columns 12, the ventilating fan 7 is installed at the top of the isolation columns 12, and a wind guide area is formed between the bottom of the ventilating fan 7 and the bottom box 1.
The periphery of the air guide area is provided with an air guide plate 13, the air guide plate 13 is in an arc shape, and the extending direction of the air guide plate 13 is consistent with the rotating direction of the ventilating fan 7.
The main control circuit board 8 is arranged on two sides or the periphery of the ventilating fan 7.
