Abstract

The utility model relates to a heat dissipation structure for induction cooker, comprising a lower cover, an IGBT, IGBT cooling fins and a fan, wherein the lower cover is provided with an air channel the inside of which is provided with at least an air deflector arranged between the fan the IGBT cooling fins; the air deflector which is the flat plate or the curved plate is normal to the lower cover and consistent with the line of centers of the fan and the IGBT; the air deflector and the lower cover are combined into a whole or separated. Because in the heat dissipation structure, the air channel is provided inside with the air deflector arranged between the fan and the IGBT cooling fins, due to the guide of the air deflector, the air from the axial fan can be directly blown on heating elements such as the electromagnetic wire coil and the IGBT cooling fins, achieving better heat dissipation effect; with the heat dissipation structure, the temperature of the IGBT cooling fins is reduced by more than 3 DEG C; moreover, due to the guide of the air deflector, the air flow in the air channel is more even and order, thereby lowering noise.

Description

The electromagnetic oven heat radiation structure
Technical field
The utility model relates to a kind of electromagnetic oven heat radiation structure.
Background technology
Electromagnetic oven is that the principle of utilizing electromagnetic induction to produce eddy current heats pan, in the course of the work because the heating of electromagnetism drum and IGBT, and pan by ceramic panel to electromagnetic oven internal radiation heat, make the electromagnetic oven temperature inside than higher.The radiator structure of existing electromagnetic oven is the aerofoil fan parallel with lower cover to be installed covering down, and the air channel is set cold wind is blowed to as heat generating components such as IGBT, electromagnetism drums, then through covering the air outlet discharge of setting down.But the aerofoil fan self-characteristic is air inlet through hollow shaft and axially air-out, and directly towards loam cake or panel, the heat radiation wind direction is at random, and radiating effect is poor, and the cooling-down effect of heat generating components is undesirable.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of efficient height, electromagnetic oven heat radiation structure that noise is little are provided, and the temperature rise of the inside components and parts of electromagnetic oven is reduced.
A kind of electromagnetic oven heat radiation structure comprises lower cover, IGBT, IGBT fin, fan, under cover the air channel be set, it is characterized in that at least one wind deflector is set, and wind deflector is between fan and IGBT fin in the air channel.
Described wind deflector is perpendicular to lower cover, and is consistent with the line of centres of fan and IGBT.
Described wind deflector is flat board or curved slab.
The height of described wind deflector is 2~50mm.
Described wind deflector and lower cover are one or split.
Adopt this radiator structure, owing in the air channel, be provided with a wind deflector, wind deflector is between fan and IGBT fin, can be with the air-out of aerofoil fan guiding by wind deflector, make the wind of fan directly blow to electromagnetism drum and these heater elements of IGBT fin more swimmingly, reach great heat radiation effect, general that the direction of wind deflector is consistent with the line of centres of IGBT with fan, increased effective wind rate by the IGBT fin, checking by experiment adopts this radiator structure that the temperature of IGBT fin is reduced more than 3 degree; Because the guiding of wind deflector, the flow direction has reduced noise more evenly, in order in the air channel.
Description of drawings
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the schematic diagram of an embodiment of the utility model electromagnetic oven heat radiation structure;
Among the figure: 1, fan; 2, lower cover; 3, IGBT fin; 4, wind deflector; 5, air channel; 6, IGBT
Embodiment
Utility model electromagnetic oven heat radiation structure as shown in Figure 1, a kind of electromagnetic oven heat radiation structure, comprise lower cover 2, IGBT 6, IGBT fin 3, fan 1, under cover air channel 5 be set, two wind deflectors 4 are set in air channel 5, and between fan 1 and IGBT fin 3, wind deflector 4 is perpendicular to lower cover 2, highly be 45mm, approaching parallel with the line of centres of fan 1 and IGBT6.Wind deflector 4 is one-body molded for being injected into lower cover 2.
Because the guiding of wind deflector 4 makes the wind of fan 1 directly blow to IGBT fin 3 heater elements such as grade more swimmingly, reaches great heat radiation effect; The flow direction in the air channel 5 has reduced noise more evenly, in order.

Claims (5)

1. an electromagnetic oven heat radiation structure comprises lower cover, IGBT, IGBT fin, fan, under cover the air channel be set, it is characterized in that at least one wind deflector is set, and wind deflector is between fan and IGBT fin in the air channel.
