Description
Technical field
It the utility model is related to a kind of radiator structure of cooking apparatus.
Background technology
Carry the cooking apparatus of internal forced air cooling, such as the electromagnetic oven with cooling fan, electric cooker, electricity on the market at present
Pressure cooker, cooking machine, various food cooking machines, all using blowing radiator structure is forced, are all placed in air inlet, in outlet air by fan
Fan is not provided with mouthful, forces the air-flow of blowing easily to produce air-flow vortex and air flow shortcircuit in internal air passage, is produced a large amount of
Air flow losses, and heat source is effectively passed through in unmanageable flow field, heat source cooling effect is poor, and radiating efficiency is low.Due to internal each heat source
Component obtain cooling effect it is poor, much cooking apparatus on the market some in order to avoid long-time maximal work using heat
Power is reduced after some minutes causes performance to decline；Some increase fan but occupied space is big, increases inappropriate rotating speed
Cause high noise fan life low；Some use the blowing in parallel of multiple fans or with independent multiple fans to corresponding independent fever
Region flow field quenching, of high cost, radiator structure layout difficulty etc. is many unfavorable.
For example, market is typically dried, the ordinary electromagnetic furnace structure of radiator structure and air passage are as shown in Figure 1, arrow is shown
Air passage path and direction signal.The air-flow that fan produces divide into region everywhere：Region 1 is mainly that circuit board main portion dissipates
Heat, the air quantity of fan that this region is got substantially 40%, heat dissipation are fine；Region 2 is mainly the heat dissipation of coil sections disk, this region is divided
The air quantity of fan substantially 30% obtained, herein since coil panel has tied up thickness direction major part space, passage is narrow so that warp
The gas-flow resistance for crossing coil panel becomes larger, so air-flow it is most of all from there coil panel and side enclose it is relatively broad low between muscle
Resistance channel flows out, so as to form air flow shortcircuit, it is difficult to forces most air-flows effectively to pass through coil panel；Region 3 is predominantly another
The circuit board remainder heat dissipation of coil sections disk and its air passage order rear side, the air quantity of fan got substantially 20%.This portion
Subregion area is broad, and air quantity is small, easily produces air-flow vortex so as to reduce cooling effect again；And air passage front end coil herein
The temperature of disk can be added to this partial circuit plate on rear side of the order of air passage, and high temperature can cause the circuit board service life to greatly shorten very
To damage；For the low flow volume region on air passage, the coil panel positioned at herein is partially in the environment of head temperature accumulation in region 4
Under, and persistently cannot effectively radiate, more easily damage.
The structure such as the common electric pot of radiator structure, pressure cooker and air passage such as Fig. 2 institutes for another example market is typically dried
Show, arrow show air passage path and direction signal.The air-flow that air inlet fan produces divide into two wind paths：Wind path 1 passes through
Circuit board and heat sink thereon；Wind path 2 passes through coil panel；Two wind paths respectively cool down two regions, several diverted last
It is aggregated into the air outlet outflow of the back lower place.Due to radiating respectively, the air quantity of each region distribution be it is limited, it is rarer on air passage
It is overlapping.Air passage distance is long and several diverted, increases air resistance coefficient, reduces the total blast volume of whole system.
Air draught heat dissipation cooking apparatus structure for fan postposition, such as described in Chinese patent CN201220636139
For electromagnetic oven air channel structure as shown in figure 3, since the air-flow of negative-pressure air-suction formation is generally all than more uniform, air-flow can be comprehensively and opposite
Fifty-fifty low speed flows through the ample area in air passage, if only putting thermo-responsive heat source element IGBT, bridge heap etc. and its heat sink
Ample area on this air passage, and the total blast volume that the radiator fan of the cooking apparatus such as ordinary electromagnetic stove and electric cooker produces is
Limited, the air quantity very little distributed is accounted at the heat sink of this ample area fraction sectional area, and wind speed is very low, and wind speed is usually low
In 1.0 meter per seconds, the air at room temperature of this wind speed e insufficient to cooling heat source element IGBT, bridge heap etc. and its heat sink.If use
Other heat-removal modalities (such as heat dissipation film) make its heat sink enlarged cross section product seem simultaneously at present full of this ample area to close
It is uneconomical.
To sum up, tradition force blowing radiator structure be by fan in body preposition, wind of the air-flow from air inlet and herein
Fan enters, then blows to internal each heat source component (main power member of such as electromagnetic coil disk or electrothermal heat-generating disc at the same time or successively
Part and its periphery, and have the circuit board of spontaneous heat power consumption etc.), air-flow is flowed out from air outlet again.This traditional structure heat dissipation effect
Rate is low, it is difficult to improves and optimizates.
