Abstract
The utility model relates to a heat radiation structure of electromagnetism stove, including base (1), circuit board (2), bridge rectifier (21) and IGBT (22), wherein circuit board (2) are adorned admittedly in base (1), and bridge rectifier (21) and IGBT (22) are installed on circuit board (2), its characterized in that insulating heat-conducting plate (3) have been installed respectively to the position that corresponds with bridge rectifier (21) and IGBT (22) on base (1), and bridge rectifier (21) and IGBT (22) are hugged closely respectively on insulating heat-conducting plate (3). The utility model discloses owing to adopt on the base and installed insulating heat-conducting plate respectively with the position that bridge heap and IGBT correspond, bridge heap and IGBT hug closely the structure on insulating heat-conducting plate respectively, and the heat that bridge heap and IGBT produced transmits for base shell through insulating heat-conducting plate, and then discharges the heat to the exterior space, the utility model discloses not only simplify the structure with fin and fan heat dissipation, be favorable to the design of electromagnetism stove inner structure, the cost is reduced moreover.
Description
Technical field
The utility model relates to a kind of radiator structure of electromagnetic oven, belongs to the improvement technology of the radiator structure of electromagnetic oven.
Background technology
Existing electromagnetic oven product is to rely on alternating magnetic field to produce eddy current in the bottom of a pan food is heated, and its operation principle is: rely on bridge heap on the circuit board to carry out after the rectification by opening of not stopping of power transistor (IGBT) again, turn-off and produce alternating magnetic field.Therefore, bridge heap and power transistor (IGBT) can produce a large amount of heats at work, overheated for preventing, device to bridge is piled and power transistor (IGBT) dispels the heat generally all is housed in the electromagnetic oven, concrete radiator structure is: aluminum thermal fin is installed on the circuit board, the bridge heap of band pin and power transistor (IGBT) are fixed on the circuit board after being fitted on the fin again, and the circuit board side is installed blower fan and carried out the forced circulation heat radiation facing to fin.There is following shortcoming in this heat abstractor: by the heat radiation of fin and blower fan, though can reach radiating effect, the cost height, and the two all is bigger parts, has occupied the inner no small space of electromagnetic oven, is unfavorable for the simplification of structural design.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of simple in structure that it is little to occupy volume, easy for installation, cheaply the radiator structure of electromagnetic oven.
The purpose of this utility model reaches by following technical proposals: a kind of radiator structure of electromagnetic oven, comprise base, circuit board, bridge heap and I GBT, wherein circuit board is packed in the base, bridge heap and IGBT are installed on the circuit board, it is characterized in that position corresponding with bridge heap and IGBT on the described base is equiped with the insulating heat-conductive plate respectively, bridge heap and IGBT are close to respectively on the insulating heat-conductive plate.
Above-mentioned insulating heat-conductive plate is made by mica material or heat conductive silica gel material.
Be provided with the heat radiation thin plate of aluminum below the above-mentioned insulating heat-conductive plate.
Above-mentioned base is made by the good conductor material of metal material or heat.
The foregoing circuit plate is packed in the base by screw.
The utility model is owing to adopt position corresponding with bridge heap and IGBT on base to be equiped with the insulating heat-conductive plate respectively, bridge heap and IGBT are close to the structure on the insulating heat-conductive plate respectively, the heat that bridge heap and IGBT produce passes to base shell by the insulating heat-conductive plate, and then heat row to space outerpace, the utility model is without fin and blower fan heat radiation, not only simplify the structure, help the design of electromagnetic oven internal structure, and reduced cost.
