Abstract

The utility model relates to electromagnetic oven technical field, in particular to an electromagnetic oven heat dissipation structure, which comprises an oven body. A bottom case of the oven body is a heat conductor, a heating element of the electromagnetic oven is arranged in the bottom case of the oven body, a heating radiator is arranged on the upper lateral side of the heating element, with at least a pin of the heating radiator extended and fixed on the bottom case to form a heat conducting system together with the heating radiator and the bottom case. The electromagnetic oven heat dissipation structure of the utility model utilizes the heating radiator and the bottom case to form the heat conducting system, the bottom case is utilized for dissipating heat, which relatively enlarges heat dissipating area, thereby effectively controlling temperature rising of an IGBT, a bridge stack and other elements, avoiding partly excessive temperature, ensuring stable operation of the electromagnetic oven, and relatively extending service life of the electromagnetic oven.

Description

The electromagnetic oven heat radiation structure

Technical field:

The utility model relates to the electromagentic furnace technology field, refers in particular to a kind of electromagnetic oven heat radiation structure.

Background technology:

Electromagnetic oven is that a kind of electricity that utilizes produces the stove and accessory that the magnetic line of force makes metal cooking utensil generation eddy-current heating that food is boiled, because it does not have flame, is subjected to very much people's welcome.In use, the electronic component of electromagnetic oven inside, all can generate heat as IGBT, bridge heap etc., the problem of how to dispel the heat and then generally to consider for industry, general comparatively ripe way is directly at upper sides such as IGBT, the bridge heap radiator that superposes, and is combined with radiator fan, utilizes air to flow and dispels the heat, to guarantee operate as normal such as IGBT, bridge heap, increase the service life.Yet, along with the development of electromagentic furnace technology, the tactic pattern of existing stack radiator, because its area of dissipation is limited, radiating rate is slower, causes local temperature rise too high often, so that the electromagnetic oven working stability is not good, actual heating-up temperature and design temperature differ greatly.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, provides a kind of structural good, can improve area of dissipation, avoids the too high electromagnetic oven heat radiation structure of local temperature.

For achieving the above object, the utility model comprises body of heater, the heater element of electromagnetic oven is arranged in the drain pan of body of heater, the drain pan of described body of heater is a heat carrier, can adopt the heat conductive metal material to make, and the heater element upper side is provided with a radiator, and this radiator has at least pin extension to be fixed on the drain pan, just makes and forms the heat conduction system between radiator and the drain pan.

The utility model is by being connected to radiator on the drain pan, and drain pan is a heat carrier, can utilize like this and form the heat conduction system between radiator and the drain pan, dispel the heat by drain pan, enlarge area of dissipation relatively, thereby also effectively control the temperature rise of elements such as IGBT, bridge heap, avoid local temperature rise too high, guarantee the steady operation of electromagnetic oven, the service life of also relative prolongation electromagnetic oven.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

See shown in the accompanying drawing 1, the utility model comprises body of heater 1, the heater element 2 of electromagnetic oven is arranged in the drain pan 11 of body of heater 1, drain pan 11 is a heat carrier, as adopt the heat conductive metal material to make, certainly also can adopt the nonmetallic materials of heat conduction to make, on drain pan 11, also be provided with inlet and outlet and radiator fan.

Heater element 2 comprises electronic components such as IGBT, bridge heap, at heater element 2 upper sides one radiator 3 is set, the radiator 3 bottom surfaces heater element 2 that reclines, and the upper side of radiator 3 is rule or irregular radiating surface; Radiator 3 has at least a pin 31 to extend down to be fixed on the drain pan 11, and both can or adopt mode such as welding to connect by securing member interlocking such as screw, make formation heat conduction system between radiator 3 and the drain pan 11.

During use, radiator 3 absorbs the heat of heater element 2, and dispel the heat, and form the heat conduction system between drain pan 11 and the radiator 3, the heat transferred drain pan 11 on the radiator 3 can be cooperated heat radiation by drain pan 11 like this, strengthen area of dissipation thus, improve heat radiation function, improve limited the deficiency of dispelling the heat that in the past only relied on radiator 3, improve the service behaviour of electromagnetic oven.

Electromagnetic oven described in the utility model can be platform-type or embedded, thereby the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by in the protection domain of the present utility model.
