Description
Technical field
The utility model belongs to small household appliances field, kitchen, relates in particular to a kind of radiator structure of electromagnetic oven.
Background technology
Advantages such as electromagnetic oven, cleans because product is energy-conservation as emerging machine for kitchen use product, and firing rate is fast obtain consumer's approval.IGBT power tube and rectifier bridge are the core component of electromagnetic oven, because power tube and rectifier bridge produce a large amount of heats inevitably in the switch running, need it be taken away by outside cooling system.Incomplete or the untimely direct result of dispelling the heat is to cause the temperature of electric elements too high, and the crystal structure of chip irreversible variation takes place and lost efficacy.Thereby cause shortening of electromagnetic oven service life, can cause the kitchen security incident when serious.
Now adopt the extruded aluminium section radiator with electric furnace power tube and rectifier bridge.Be subjected to the slow restriction of the solid heat transfer long heat transfer of distance, must assist heat radiation by the wind by force of fan.Existing heat dissipation wind channel design is that a fan is all element radiatings in the whole electromagnetism furnace shell, and then fan needs big air quantity, runs up.Even like this, IGBT power tube and bridge heap are near the temperature height of radiator, and away from the radiator position of IGBT power tube and bridge heap, temperature is than higher, and heat can not effectively shed.The intensive place of electronic component radiating effect is variation especially also.For reaching radiating effect, institute's assembling fan volume is bigger, and the build heaviness is unfavorable for the lightening design of complete machine.Simultaneously, the fan of rotation produces big noise sound in the course of the work at a high speed.
The utility model content
The essential technique problem that the utility model is intended to solve is to provide that a kind of volume is less, good heat dissipation effect and the low electromagnetic oven heat radiation structure of noise.
For achieving the above object, the utility model corresponding techniques scheme is:
A kind of electromagnetic oven, comprise loam cake, lower cover, control circuit, coil panel, described coil panel and described control circuit are electrically connected and place in the space of being made up of described loam cake and described lower cover, also include heater and the radiator that is connected with described heater in the wherein said control circuit, described radiator is liquid-cooling heat radiator or heat-pipe radiator.Electromagnetic oven of the present utility model comprises that also air outlet faces toward the radiator fan of described radiator, concentrates heat radiation, exempts the obstruct of other electronic components, makes the mobile of wind become more concentrated, makes its radiating effect improve.
As a kind of mode ground, described power heat abstractor is a radiator fan.Described fan directly is installed on the described radiator.By wind-force radiator is cooled off.
Described heater is that the IGBT power tube is or/and the rectifier bridge heap.
Compared with prior art, the beneficial effects of the utility model are: volume structure is little, noise is low, frivolous easy, radiating effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model electromagnetic oven;
Fig. 2 is located at structural representation on the radiator for the power heat abstractor.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Embodiment one:
Shown in Fig. 1-2, a kind of electromagnetic oven, comprise loam cake 1, lower cover 2, control circuit 3, coil panel 4, coil panel 4 is electrically connected and places in the space of being made up of loam cake 1 and lower cover 2 with control circuit 3, wherein also include heater 6 and radiator 7 in the control circuit 3, be equipped with power heat abstractor 5 on the radiator 7.Electromagnetic oven of the present utility model, power heat abstractor 5 directly are installed on the radiator 7, concentrate heat radiation, exempt the obstruct of other electronic components, make the mobile of wind become more concentrated, make its radiating effect improve.
As the preferred forms of present embodiment, power heat abstractor 5 is a radiator fan.Fan directly is installed on the radiator 7.By wind-force radiator 7 is concentrated cooling.
In the present embodiment, heater 6 is IGBT power tube and rectifier bridge heap.
Embodiment two:
The electromagnetic oven of present embodiment technical scheme, radiator 7 is different with embodiment one, and other structures are identical substantially, give unnecessary details no longer one by one.
In the present embodiment, radiator 7 is a liquid-cooling heat radiator, has fluid pipe.Liquid in the fluid pipe is realized flowing of liquid by boiling and condensation.Liquid-cooling heat radiator is commonly used in the prior art, is used to electronic element radiating more, does not provide diagram at this.Liquid inlet, liquid outlet and liquid storage space that middle fluid pipe is connected, and constitute the fluid course of a closed circuit, for obtaining bigger heat exchange area, radiator 7 is made of the dried heat exchanger plate that is stacked, liquid is caused radiator 7 through fluid pipe carry out absorbing and cooling temperature, the liquid of cooling is back to the circulation cooling in liquid storage space again.
Embodiment three:
The electromagnetic oven of present embodiment technical scheme, radiator 7 is different with embodiment one, and other structures are identical substantially, give unnecessary details no longer one by one.
In the present embodiment, radiator 7 is a heat-pipe radiator, fill with working media and utilize the decalescence of medium and heat release to carry out heat exchange in the shell of sealing, after being pumped into negative pressure in the pipe, fill, make to be sealed after being full of liquid in the imbibition core capillary porous material of being close to inside pipe wall with an amount of hydraulic fluid.One end of pipe is evaporator section (bringing-up section), the other end is condensation segment (cooling section), liquid carburation by evaporation when an end of heat pipe is heated among the Mao Renxin, steam flows to the other end and emits heat and condense into liquid under small pressure reduction, liquid flows back to evaporator section along porous material by the effect of capillary force again.So circulation oneself, heat is reached in addition-is held by an end of heat pipe.Power heat abstractor 5 is a radiator fan, blows to heat release one end.
In sum; after those of ordinary skill in the art reads the utility model file; need not creative mental labour according to the technical solution of the utility model and technical conceive and make other various corresponding conversion scheme, all belong to the scope that the utility model is protected.
