The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1-3, general electromagnetic oven heat radiation structure comprises lower cover 1 and upper cover 2, and the cavity that forms between lower cover 1 and upper cover 2 is used for holding each parts of electromagnetic oven, and described parts comprise drum, pcb board, IGBT and bridge heap etc.The electromagnetic oven heat radiation structure also comprises fan 100, fin 200 and at least one deep bead that is arranged in cavity.Deep bead comprises around the peripheral fan deep bead 310 that arranges of fan 100, two ends of fan deep bead 310 form air inlet 400 in the location towards fin and parts, the cold wind that fan 100 produces blows to inside cavity by this air inlet 400, thereby lowers the temperature for the parts in cavity.
In the electromagnetic oven heat radiation structure of the foundation embodiment of the present invention, still referring to Fig. 1-3, be oppositely arranged two the first dividing plates 510 in cavity, above-mentioned two the first dividing plates 510 begin to extend on the shell of lower cover 1 and upper cover 2 from two ends of fan deep bead 310 respectively, thereby cavity is divided into mutual isolation cup 11 and rear chamber 12, gaseous exchange can not occur between cup 11 and rear chamber 12, the cold wind that therefore enters cup 11 can only pass into from air inlet 400.Two the first dividing plates 510 can be both to be removably disposed in cavity, can be also to be fixedly installed in cavity.
Be provided with fan 100, fin 200 and cavity in cup 11, cavity is positioned at bottom the drum (not shown), is used for holding each parts of electromagnetic oven.The zone at fin 200 places belongs to middle high-temperature region, the maximum operating temperature general control is below 80 ℃, for the radiating effect that makes fin 200 reaches best, be provided with the 3rd deep bead 340 in a side of closing on fin 200, in order to the side shell of fin 200 with upper cover 2 and lower cover 1 separated.In an embodiment of the present invention, the second partition 520 perpendicular to air inlet 400 is set in cavity, cavity is divided into higher-pressure region 14 and the low-pressure area 15 of mutual isolation.In addition, second partition 520 can be both to be removably disposed in cavity, can be also to be fixedly installed in cavity.For example in an embodiment of the present invention, as shown in Figure 1, be provided with two relative draw-in grooves 800 in cavity, be used for second partition 520 is installed, this mounting means is dismountable, can insert at any time or take out second partition 520.Higher-pressure region 14 is between fin 200 and second partition 520, and the 220V zone on corresponding pcb board in this higher-pressure region 14, mainly accommodates high power capacity and inductance, and operating temperature is 75 ℃ to 80 ℃.Low-pressure area 15 mainly accommodates caloric value transformer on the low side and electric capacity between the shell of second partition 520 and upper cover 2 and lower cover 1, the operating temperature of this part parts is generally below 50 ℃.As can be seen from the above, by second partition 520 is set, between high-temperature area (higher-pressure region 14) and low-temperature region (low-pressure area 15), gaseous exchange occurs no longer.
In addition, in the electromagnetic oven heat radiation structure of the foundation embodiment of the present invention, the place also is provided with at least one air inlet deep bead at air inlet, thereby air inlet is separated into a plurality of sub-air inlets, and wherein the air inlet deep bead removably or regularly vertically arranges on lower cover 1.In an embodiment of the present invention, the air inlet deep bead comprises the first deep bead 320, the first deep bead 320 and vertically is arranged on lower cover 1 between fin 200 and fan 100, thereby forms fin air inlet 410 between an end of the first deep bead 320 and adjacent fan deep bead 310.The cold wind that passes into from fin air inlet 410 blows to fin 200.The air inlet deep bead can comprise that also the second deep bead 330, the second deep beads 330 are arranged between second partition 520 ends and fan, and can be connected with second partition 520 end contacts.Thereby form formation low-pressure area air inlet 430 between the other end of higher-pressure region air inlet 420, the second deep beads 330 and adjacent fan deep bead 310 between the second deep bead 330 and adjacent the first deep bead 320.At this moment, the cold wind of fan 100 generations blows to the interior parts in higher-pressure region 14 by higher-pressure region air inlet 420; Blow to the interior parts of low-pressure area 15 by low-pressure area air inlet 430.In addition, also can between the upper cover 2 at air inlet place and lower cover 1, rib 700 or dividing plate be set, thereby form drum air inlet 440 between upper cover 2 and rib 700.The cold wind that fan 100 produces blows to drum so that drum is dispelled the heat by drum air inlet 440, and drum belongs to high heater members, and this zone belongs to the high-temperature region, and in work, maximum temperature can reach 150 ℃.
In the electromagnetic oven heat radiation structure of the foundation embodiment of the present invention, the material for preparing two the first dividing plates 510 and second partition 520 is identical with the material of upper cover 2 or lower cover 1.The material for preparing each deep bead is identical with the material of upper cover 2 or lower cover 1.Certainly, also can adopt other exotic material preparation.
In the electromagnetic oven course of work that has according to the radiator structure of the embodiment of the present invention, because adopt the first dividing plate 510 cavity to be divided into cup 11 and the rear chamber 12 of mutual isolation, the cold wind that fan 100 produces can only enter cup 11 from air inlet, can not flow to other zone, therefore can take full advantage of the radiating efficiency of cold airflow in the heat radiation process, desirable utilization rate reaches 100%.In addition, the cold wind that fan 100 produces enters corresponding fin region, higher-pressure region 14, low-pressure area 15 and drum region from fin air inlet 410, higher-pressure region air inlet 420, low-pressure area air inlet 430 and drum air inlet 440 respectively, therefore cold wind can arrive the purpose zone rapidly by each sub-air inlet, having dredged cold wind flows, make cold wind flow more orderly and even, also reduced noise.In addition, second partition 520 is kept apart middle high-temperature area (fin region and higher-pressure region 14) and low-temperature region (low-pressure area 15) fully, on the one hand, between high-temperature area and low-temperature region gaseous exchange can not occur, reduced the resistance that convection current produces, thereby accelerated flowing of cold wind, the speed of coming out of the stove that has then improved the radiating efficiency of cold wind and accelerated thermal current; On the other hand, fin is isolated in the zone that communicates with parts in higher-pressure region 14, has therefore improved the efficient of fin; On the other hand, because high temperature gas flow can not mix with low-temperature airflow again, so the temperature in low-temperature region can be maintained, and avoids being subject to the impact of high temperature gas flow and again rises.
As can be seen from the above, because adopt the heat-sinking capability that has improved electromagnetic oven according to the electromagnetic oven heat radiation structure of the embodiment of the present invention, therefore be equal on the basis of radiating effect in acquisition, can select the lower fin of heat dispersion, thereby reduce the mainboard cost; Also can select the lower electronic devices and components of temperature resistant grade, reduce equally the mainboard cost; Nor need to add fan housing on fan, simplify the structure and saved cost.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improve and conversion all should belong to the protection domain of claims of the present invention.
