Compared with the prior art, the fan housing with an upper air outlet is additionally arranged above the fan, so that the airflow that enters into the interior of the electromagnetic oven through the fan can change the direction and can be concentrated to flow to the elements requiring the cooling, thereby reducing the phenomenons such as the air leakage and the chaos of the wind passage; moreover, the axial airflow of the fan is guided by the fan housing, thereby being free from being directly blown to an operation display board, and preventing the operation display board from being corroded and polluted by the water and the oil, which are thrown by the fan.
Description
Technical field
The utility model relates to the electromagentic furnace technology field, particularly a kind of electromagnetic oven heat radiation structure.
Background technology
Electromagnetic oven is that the principle of utilizing electromagnetic induction to produce eddy current heats pan, in the course of the work because the heating of electromagnetism drum and IGBT, and pan by bearing panel to electromagnetic oven internal radiation heat, make the electromagnetic oven temperature inside than higher.The radiator structure of existing electromagnetic oven is the aerofoil fan parallel with lower cover to be installed covering down, and the air channel is set cold wind is blowed to as heat generating components such as IGBT, electromagnetism drums, then through covering the air outlet discharge of setting down.But the aerofoil fan self-characteristic is air inlet through hollow shaft and axially air-out, and directly towards loam cake or bearing panel, the heat radiation wind direction is at random, and radiating effect is poor, and the cooling-down effect of heat generating components is undesirable.
China's utility model patent discloses a kind of cooling system ZL200720068801.7 number.This electromagnetic oven heat radiation system comprises coil panel, air channel, fan and mainboard, and its air channel is rhombus or approximate rhombus and is provided with opening, and fan is arranged in the air channel, and mainboard is arranged on the opening direction in air channel, and coil panel is arranged on fan and mainboard top.This cooling system can be concentrated fan wind in the horizontal direction by the rhombus air channel and is blowed to mainboard, and still, it does not solve axial direction upwind problem at random.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of electromagnetic oven heat radiation structure is provided, so that electromagnetic oven can effectively reduce temperature rise and protect electromagnetic oven operation display board not corroded and pollute.
To achieve these goals, the utility model electromagnetic oven heat radiation structure is reached by the following technical programs:
A kind of electromagnetic oven heat radiation structure, it comprises lower cover, fan, is located at the deep bead of lower cover, described radiator structure also comprises a fan housing, described fan housing hides in fan top and is provided with air outlet, described fan housing be fixed in deep bead or under cover.
Compared with prior art; the utility model electromagnetic oven set up above the fan have on the fan housing of air outlet; the air-flow that makes fan suck electromagnetic oven inside changes wind direction; can concentrate and blow to the element that needs to reduce temperature rise effectively; reduced leak out, the phenomenon of air channel confusion; and the fan axial flow is guided by fan housing, can directly not blow to the operation display board of its top, can protect the operation display board can not corroded because of water, the greasy dirt that fan throws away and pollute.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model embodiment schematic diagram.
Fig. 2 installs schematic diagram behind the drum for the utility model embodiment.
Fig. 3 is the utility model embodiment fan housing schematic diagram.
Fig. 4 removes the fan housing schematic diagram for Fig. 1.
Fig. 5 increases the wind deflector schematic diagram for Fig. 4.
Among the figure: 1, lower cover; 10, air inlet; 12, air outlet; 2, IGBT; 20, IGBT fin; 22, circuit board; 4, drum; 5, fan housing; 50, main part; 52, extension; 500, air guiding wall; 501, go up air outlet; 503, fixed leg; 505, projection; 520, fixing hole; 6, deep bead; Wind deflector 7.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
To shown in Figure 5, the applied electromagnetic oven of the utility model electromagnetic oven heat radiation structure comprises lower cover 1, IGBT2, IGBT fin 20, circuit board 22, drum 3, fan 4, fan housing 5, deep bead 6 and wind deflector 7 as Fig. 1.
Described lower cover 1 is provided with air inlet 10 and air outlet 12, and fan 4 is installed in air inlet 10 places.Described deep bead 6 roughly is semicircle shape, its and from lower cover 1 inner surface air outlet around upwards vertical extension one-body molded with lower cover 1.Deep bead 6 openings are towards IGBT2, IGBT fin 20 and circuit board 22, and so, deep bead 6 can blow to the wind that fan 4 sucks on the said elements in the horizontal direction.
As shown in Figure 5, deep bead 6 opening parts can also be established the wind deflector 7 of one or more roughly curved sheets.Wind deflector 7 and lower cover 1 are one-body molded and from the upwards vertical extension of lower cover 1 inner surface.Can the position and the shape of wind deflector 7 be set according to each heater members layout difference of master control borad, thereby adjust the and arranged on left and right sides wind flow, the wind that comes out from deep bead 6 openings in the horizontal direction can selectively be shunted.
When fan 4 work, constantly suck air and form air-flow, at first air is blowed to fan housing 5, the air-flow that fan housing 5 will blow out vertically changes over and is roughly horizontal direction, the part air communication is crossed arch air guiding wall 500, distributes to top drum 3, makes drum be operated in suitable temperature.And all the other most of air communication are crossed the guiding of fan housing 5 and deep bead 6 and are blown to IGBT2, IGBT fin 20, circuit board 22.Because the design of fan housing 5 forms obvious and unimpeded air channel, the wind that fan 4 is sent is concentrated and is effectively blowed to the element that needs to reduce temperature rise, and reduction is leaked out, the phenomenon of air channel confusion.Following table be under the normal temperature in a type in the temperature rise correction data that each device before and after the fan housing is installed:
As can be seen from the above table, install fan housing 5 after, IGBT2, the inductance temperature rise range of decrease is bigger, other device temperature rises all have certain amplitude to descend.Consider the operating temperature limit value of device own, can want the scheme that reaches by regulating air outlet 501 and wind deflector 7 realizations.
Existing electromagnetic oven is positioned at the fan top owing to be installed on the operation display board of loam cake, and fan sucks to such an extent that water and greasy dirt can get rid of to the operation display board from the electromagnetic oven outside, uses for a long time because of greasy dirt, and aqueous vapor etc. easily cause operates that display board is corroded or dirtyly cause damage.The design of the utility model fan housing 5 can be avoided the operation display board of the straight blower fan of wind 4 tops, plays the effect of waterproof and greasy dirt.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
