Detailed description of the invention
In order to be more clearly understood that the above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.It should be noted that when not conflicting, embodiments herein and the feature in embodiment can be mutually combined.
Elaborate a lot of detail in the following description so that fully understanding the present invention; but; the present invention can also adopt other to be different from other modes described here to implement, and therefore, protection scope of the present invention is by the restriction of following public specific embodiment.
Describe according to the electromagnetic oven invented described in some embodiments referring to Fig. 1 and Fig. 2.
As it is shown in figure 1, electromagnetic oven, including: upper cover (not shown), base plate 1, master control borad 2, heat-conducting plate 6, coil panel 3, fan 4 and radiator 5.
Base plate 1 and upper cover constitute accommodation chamber.
Master control borad 2 is arranged in accommodation chamber, and is provided with heatable electric elements 201 on master control borad 2.
Coil panel 3 is positioned at the middle part holding chamber.
Fan 4 is arranged in accommodation chamber and blows to master control borad 2, and fan 4 simple in construction is with low cost, and can effectively cool down radiator 5.
Radiator 5 is connected with described master control borad 2, and is positioned on the air outlet direction of fan 4, and specifically, radiator 5 is fin or heat-pipe radiator.
Heat radiating fin structure is simple, cheap；Heat-pipe radiator is safe and reliable, good heat dissipation effect.
The kind of radiator 5 is also a variety of, does not just repeat one by one at this, and those skilled in the art can select suitable radiator according to concrete requirement and demand.
Heat-conducting plate 6 is connected with electric elements 201, and absorbs the heat that electric elements 201 produce, and transfers heat to radiator 5, preferably, as depicted in figs. 1 and 2, described heat-conducting plate 6 is an imposite and is covered on electric elements 201, and contacts be connected with electric elements 201 and radiator 5 respectively.The setting of heat-conducting plate 6 can effectively solve the problem that the problem that the part electric elements radiating effect caused due to electric elements position air quantity difference is not good, namely the radiating condition of electric elements in the defective region that dispels the heat on master control borad is improved, so that each electric elements can be dispelled the heat effectively, and then extend the service life of electric elements.
It addition, contacting the electric elements 201 connected with heat-conducting plate 6 is one or more in IGBT, Qiao Dui, filter capacitor, switch chip, choking-winding and transformator.
In one embodiment of the invention, heat-conducting plate 6 being provided with contact feet, heat-conducting plate 6 contacts connection by contact feet with described electric elements 201.
In one particular embodiment of the present invention, as in figure 2 it is shown, contact feet is multiple flaps 601 extended downwardly from, heat-conducting plate 6 contacts connection by flap 601 with electric elements 201.It is low that electric elements 201 on master control borad 2 have height to have, heat-conducting plate 6 is connected with relatively low electric elements 201 by flap 601 while being connected with higher electric elements 201, all electric elements 201 that can produce heat can be connected by the setting of flap 601 with heat-conducting plate 6, so that effectively being dispelled the heat of each electric elements 201.
Or, contact feet is the boss (not shown) being provided with multiple hollow on heat-conducting plate 6, and electric elements 201 insert in boss and contact connection with heat-conducting plate 6.The boss of hollow can wrap up electric elements 201, which increases the contact area of heat-conducting plate 6 and electric elements 201, thus adding the heat absorption efficiency of heat-conducting plate 6.
Above example, be on heat-conducting plate 6 at the flap 601 stretched out and/or cannular boss as contact feet to illustrate that heat-conducting plate 6 is connected with the contact of electric elements 201, so that electric elements 201 are carried out heat conduction and heat radiation, in fact, the kind of electric elements 201 is a lot, shape is also different, in order to make heat-conducting plate 6 and electric elements 201 better contact with and contact area maximization, the contact feet of difformity, different size and different angles can be set on heat-conducting plate 6, just no longer repeat one by one here.
In an embodiment of invention, it is provided with heat-conducting layer (not shown) between heat-conducting plate 6 and electric elements 201, it is preferable that heat-conducting layer is thermal conductive silicon lipid layer.The setting of heat-conducting layer adds the heat transfer efficiency between electric elements and heat-conducting plate, thus improve the rate of cooling of electric elements；Silicone grease has good heat conductivity, nonpoisonous and tasteless, and non-corrosiveness, physicochemical properties are stable.
