A kind of radiator structure

Technical field

The utility model relates to technical field of heat dissipation, in particular to a kind of for electromagnetic heating control module in kitchen appliance field And the structure that coil radiates.

Background technique

Electromagnetic induction heating electric appliance generally includes upper cover, pedestal, coil panel and coil brace, automatically controlled mainboard, and radiator is interior Several parts such as pot.Wherein, the power device (such as IGBT) on automatically controlled mainboard (usually using PCB as form) at work, can generate A large amount of heat.In addition to power component, other electronic components on mainboard can also generate certain heat.In addition, electromagnetic induction adds Thermal modules are using alternating magnetic field caused by inductance coil disk, so that the magnetic conductivity object being placed in the magnetic field generates vortex, from And it generates heat.Therefore, when electromagnetic induction heating module works, the inductance coil disk being energized can also generate a large amount of heat, these If heat cannot be timely and effectively discharged to except electromagnetic induction heating module, it is excessively high to will lead to temperature in equipment, and then influence The normal work of device components, or even damage component.In the prior art, it will usually which wind groove formula is installed on automatically controlled mainboard Radiator, and a fan towards radiator is set, to realize the heat dissipation of automatically controlled mainboard, while the air-flow generated using fan, Take away the heat of coil sections disk generation.Currently, the radiating mode in kitchen appliance field for electromagnetic heating control module is adopted mostly Mounting means is stacked with simple fan, radiator is blowed to merely with the wind direction that fan itself generates and other needs to radiate Component.Aforesaid way does not form effective air duct, and distinguished and admirable at random, wind pressure is obviously insufficient, and radiating efficiency is lower, and structure Complexity, volume is larger to be unfavorable for production assembling.

For example 203693249 U of CN discloses the cooker body and electric cooker of a kind of electric cooker, the air-flow blown out upwards from fan After left side is stopped by wind deflector 73, coil panel is blowed to across radiator 50, although design can guarantee all air-flows all Coil panel is blowed to, but since the main thermal component of electric cooker is exactly radiator, the radiating airflow temperature produced by boasting from radiator Degree increases obviously, then blows to coil panel, it may appear that the case where being radiated using thermal current for heat generating components, and do not have above fan Effective wind pressure cavity is formed, it cannot effective hoisting wind pressure.

For example 203873542 U of CN discloses a kind of electric cooker, after the air-flow blown out from fan is stopped by wind deflector, wears Cross notch and blow to coil panel, although design can guarantee that most air-flow all blows to coil panel, still have part from The high temperature gas flow that radiator is produced by boasting can blow to coil panel, it may appear that the case where being radiated using thermal current for heat generating components, and Because open notch is very big, effective wind pressure cavity is not formed above fan, it cannot effective hoisting wind pressure.Most Afterwards it is exactly only seldom a part of by the air-flow of radiator, and due to the slant setting of fan, leads to this fraction not Be it is very stable, influence radiating efficiency.

For example CN 203987534U discloses a kind of electric pressure cooking saucepan, the air-flow of fan blowout is divided into two parts, a part Coil panel has not just been blowed to directly by the guidance of guide plate, after another part air-flow blows to radiator, but due to electric cooker Main thermal component is exactly radiator, and the radiating airflow temperature produced by boasting from radiator increases obviously, then blows to coil panel, meeting Occur using thermal current being the case where heat generating components radiates, and does not form effective wind pressure cavity above fan, it cannot Effective hoisting wind pressure.

For example CN 204335270U discloses a kind of electric cooker, the air-flow of fan blowout is divided into two parts, a part warp The guidance for crossing split-wind plate 4 directly blows to coil panel, and another part air-flow is vented directly to module-external after blowing to radiator, practical Upper only two-way air-flow, and effective wind pressure cavity is not formed above fan, cannot effective hoisting wind pressure, can not increase Add the air quantity and wind pressure into radiator.

For example CN 203647052U discloses a kind of electric cooker, the air-flow of fan blowout is divided into two parts, a part warp The guidance for crossing wind deflector 6 directly blows to coil panel, and another part air-flow is vented directly to module-external after blowing to radiator, practical Upper only two-way air-flow, and effective wind pressure cavity is not formed above fan, cannot effective hoisting wind pressure, can not increase Add the air quantity and wind pressure into radiator.
