Fig. 3 is the structure partial sectional view of heat radiator and transformer in the utility model preferred embodiment.
Embodiment
Hereafter with specific embodiment, the utility model is described further by reference to the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, a kind of portable magnaflux with automatic cooling function, comprises cabinet 10, fan group 20, transformer group 30, temperature sensor and control circuit 40 and switch instrument, pilot lamp and connector socket 50.
Cabinet 10 comprises shell 101 and skeleton 102.Further, described shell comprises the first component and second component that are tightly connected, makes the classification of waterproof that shell can reach certain.Described first component comprises integrated front panel 1011, base plate 1012 and rear panel 1013; Described second component comprises integrated left and right side plate 1014,1015 and top board 1016.Skeleton 102 plays the effect that strength support and parts are installed.
In the present embodiment, casing 101 and skeleton 102 select aluminium alloy manufacture; Certainly, shell 101 also can select hard plastics, under the prerequisite of proof strength, alleviates weight.
The left and right side plate 1014,1015 of shell 101 has the first air inlet 1017, and rear panel 1013 top has exhaust outlet 1018, and bottom has the second air inlet 1019.
Described first air inlet 1017, second air inlet 1019 and exhaust outlet 1018 are separately installed with screen pack, prevent dust simultaneously, serve certain waterproof action.
Front panel 1011 installs switch instrument, pilot lamp and connector socket 50, rear panel 1013 bottom installation insurance silk and instrument master switch, top board 1016 is arranged a groove, one end of groove arranges a rotating shaft and is rotationally connected in carrying handle 10110, therefore, carry handle 10110 can be placed in the groove of top board, can pull up during use, can be placed in groove after placement.
Fan group 20 comprises the extraction fan 201 being arranged on exhaust outlet 1018 position, cabinet 10 interior back panel 1013 top, and air intake surface is towards in cabinet 10, and be arranged on skeleton 102, and vertically with the first air inlet 1017 to arrange, and outlet air surface is towards the air blowing fan 202 of described transformer group 30.
Transformer group 30 comprises transformer 301 and heat radiator 302, and transformer 301 is arranged in heat radiator 302, is positioned at cabinet 10 Internal back end.Because transformer 301 temperature rise in whole instrument is fast the highest, therefore mounting temperature sensor 401 on heat radiator 302, in real time the rising situation of its temperature of monitoring.Transformer group 301 overhead height lower than the bottom of extraction fan 201, thus ensures that top is unobstructed, can be discharged to cabinet outside fast after hot-air rises to this place by extraction fan 201.Control circuit 402 is arranged on cabinet front portion, and near front panel 1011 position, vertical base plate 1012 is arranged on skeleton 102, and is arranged on the back of air blowing fan 202, relative with its air intake surface.In addition, in cabinet 10, between device, wiring should have arranging along skeleton 102 of rule.
Press instrument switch, instrument power source pilot lamp is bright.Press pre exciting switch, start to magnetize workpiece.When the temperature that temperature sensor 401 detects does not reach early warning upper temperature limit, fan group 20 does not operate, and now instrument leans on the first air inlet 1017, second air inlet 1019 of self and exhaust outlet 1018 to dispel the heat.When temperature exceedes early warning upper temperature limit, extraction fan 201 and air blowing fan 202 are started working.The air entered from the first air inlet 1017 is constantly blowed to heat radiator 302 by air blowing fan 202.Because cold air constantly enters from the first air inlet 1017 of both sides, and control circuit 402 is relative with the air intake surface of air blowing fan 202, therefore control circuit 402 is also cooled, thus improves the serviceable life of components and parts.Air blowing fan 202 is dried to the heat radiator 302 of parcel transformer, takes away the hot-air around heat radiator 302, due to the heat-conducting effect that heat radiator 302 is good, therefore, it is possible to reduce the own temperature of transformer 301 fast.The hot-air on heat radiator 302 top is discharged by extraction fan 201 simultaneously, under the draft effect of extraction fan 201, second air inlet 1019 of rear panel 1013 bottom also constantly enters cold air, thus the temperature of transformer is constantly declined, when being reduced to early warning lowest temperature, control circuit 402 sends instruction fan group 20 and quits work.Temperature province between early warning upper temperature limit and lower limit can be used as the buffer zone that fan group 20 starts, thus avoids the voltge surge that fan group 20 brings at single temperature frequent starting.By above-mentioned process, not only maintain instrument and work in desirable temperature range, also reduce the waste of noise that fan continuous firing brings and electric energy simultaneously.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
