The specific embodiment
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
To shown in Figure 6, it is the specific embodiment of electromagnetic oven of the present invention as Fig. 1, and it comprises panel 11, shell, display circuit board 121, movement 13.Described shell comprises outer casing upper cover 12 and shell lower cover 14.Described panel 11 and display circuit board 121 are installed on the outer casing upper cover 12.Shell lower cover 14 is provided with air inlet 141 and air outlet 142.
During installation, the first step is fixed on control circuit board 132 on the lower casing 1312; In second step, drum 134 is fixed on the upper casing 1310; In the 3rd step, fan 133 is fixed on the upper casing 1310; The 4th step was fixed on lower casing 1312 on the upper casing 1310, offered rectangle fluting on upper casing 1,310 one sidewalls, and the part of control circuit board 132 is stretched out outside inner casing 131; The 5th the step, with thermal insulation board 130 sealing and fixing on upper casing 1310; In the 6th step, movement 13 is fixed on the lower cover 14.After the installation, the power adjusting knob 1324 of control circuit board 132, power supply access port 1322, holding wire access port 1326 all stretch out inner casing 131, the convenient adjusting and installation.
After installing by the way, movement 13 is except inner casing air inlet 16 and inner casing air outlet 18, other parts seal substantially, so, drum 134, fan 133, control circuit board 132 are contained in the relative sealed space, are a significant benefit to the heat radiation of drum 134, control circuit board 132, IGBT and IGBT fin.
The inner casing 131 of electromagnetic oven of the present invention also can only have upper casing 1310, and upper casing 1310 is mounted on the shell lower cover 14, and its sidewall contacts with shell lower cover 14 and seals its contact position in case leak-stopping wind with glue or other modes.Drum 134, fan 133, control circuit board 132 also can be mounted on the shell lower cover 14 and by upper casing 1310 and be contained in the relative sealed space.
Existing electromagnetic oven fan is influenced by machine inner structure to the heat radiation of components and parts bigger, easily form the internal heat dissipating dead angle, the part air-flow is forming eddy current in casing, because the employing of suction-type fan makes machine intimate that certain blast be arranged, the slit of existing electromagnetic oven structure upper and lower covers junction is run off certain air quantity, and heat radiation air quantity utilization rate is low; And, existing electromagnetic oven heat radiation structure is subject to the influence of appearance and modeling, different appearance and modelings has determined the structure of internal heat dissipating layout, often there is each the components and parts temperature rise in the shell of different appearance and modelings of same parts to have in the test than big-difference, the temperature rise of individual metablocks device exceeds standard, the easy like this delay that causes the construction cycle, the raising of R﹠D costs and unit cost.In the electromagnetic oven of the present invention, fan 133 passes through air inlet 141, inner casing air inlet 1310 with wind inspiration movement 13 inside, fan 133 with drum 134, control circuit board 132, IGBT and the IGBT fin of wind in movement 13, blows out from inner casing air outlet 1312, air outlet 142 more then.But inner casing 13 has only inner casing air inlet 1310 and the turnover of inner casing air outlet 1312 air feeds, so, drum 134, control circuit board 132, IGBT and IGBT fin are installed concentratedly in inner casing 131 or by inner casing 131 and are accommodated, can make more concentrated drum 134, control circuit board 132, IGBT and the IGBT fin of blowing to of wind, make it concentrate heat radiation, and reduce air-flow dead angle, air channel, effectively reduce the excessive loss of air quantity, avoid air-flow to blow to the place of no heat dissipation element, improve the utilization rate of heat radiation air quantity, effectively reduce the components and parts temperature rise, improve machine life.Behind contrast test, under the similarity condition, electromagnetic oven of the present invention reduces by 2 degree compared to existing electromagnetic oven IGBT temperature rise, and the drum temperature rise reduces by 10 degree, and other components and parts all have the temperature rise range of decrease in various degree.
The present invention can make the shared movement of different types of machines, has reduced the influence of appearance and modeling to machine intimate radiator structure layout, has versatility; Fan 133, drum 134, fin are fixed on 131 li of inner casings together with control circuit board 132, are convenient to concentrate heat radiation, this cooling system does not almost have the air quantity loss, dead angle, no air channel, and the radiating efficiency height, and reduced the electromagnetic oven noise; This movement with great heat radiation effect can become unitized standard component, and different types of machines can use general movement, have improved production efficiency, effectively reduces the construction cycle, reduces R﹠D costs and unit cost.
