The invention discloses an electric heating plate for a vacuum drying oven. The electric heating plate for the vacuum drying oven comprises a wire winding plate and a resistance wire, wherein the resistance wire is uniformly wound on the wire winding plate; a thermal couple is fixedly arranged at one end of the wire winding plate; the upper surface and the lower surface of the wire winding plate are respectively in contact with a heat-conducting insulating plate and the wire winding plate and the heat-conducting insulating plate are arranged in the shell. The electric heating plate for the vacuum drying oven has the advantages of simple structure, uniform heating, easiness in realization and extremely high practicability, and is suitable for working in vacuum environments.
Description
Technical field
The present invention relates to heating in vacuum production technical field, particularly a kind of electric boiling plate for vacuum drying oven.
Background technology
Laser welding enters the high-speed developing period in 21 century.With all kinds of laser generators to high-power, lighting
With the development of economization, laser welding is little due to energy high concentration and heat affected area, meet high-quality, low consumption, efficiently, cleaning,
The technical characterstics such as heat affected area is narrow, joint distortion is little, flexible operation, its development prospect is known no measure.
The encapsulation being widely used in the microwave device of radar generally adopts laser welding, needs device before laser welding
Part is placed in vacuum drying oven and carries out heating degassing processing.It is provided with multilamellar electric boiling plate in vacuum drying oven, device is placed on two-layer
Between electric boiling plate, in the heat transfer on electric hot plate to device, will there is a vacuum pump that vacuum is dried by heat radiation simultaneously
Case evacuation, thus reach the purpose that device is heated with degasification.Therefore, simply clean electric boiling plate is very heavy to vacuum drying oven
Will.
Content of the invention
The technical problem to be solved is, not enough for prior art, provides that a kind of structure is simple, homogeneous heating
The electric boiling plate for vacuum drying oven.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of electrical heating for vacuum drying oven
Plate, including around filament plate and resistance wire, described resistance wire uniform winding is described on filament plate；Described it is fixed with heat around filament plate one end
Galvanic couple；Described respectively contact with one block of heat conductive insulating plate around filament plate upper and lower surface, and described around filament plate with heat conductive insulating plate
It is arranged inside the shell.
Described wherein three sides around filament plate all offer at least one breach, and described resistance wire is twined by described breach
Described in being wound on filament plate, and described resistance wire is wound around spirality described on filament plate；Two wiring of described resistance wire
End, described thermocouple be arranged at described around the side not opening up breach of filament plate；Heat conduction on the described upper surface around filament plate is exhausted
Cover plate is coated with listrium.
Described cover plate and shell are all made using rustless steel；Described it is micarex around filament plate, heat conductive insulating plate.
Described resistance wire material be chrome-nickel bandlet, described chrome-nickel bandlet thickness be less than 0.2mm, width be 2～

Contact with shell 5 in preventing resistance wire 2.
As shown in figure 3, the material in the heat conductive insulating plate 3 around filament plate 1 upper and lower surface is micarex, cover plate 4 and shell 5
Material is the rustless steel that thickness is less than 0.5mm.
As shown in Figure 1, Figure 2, Figure 3 shows, around one end extracting power supply cord of filament plate 1 and arrange the thermocouple 6 of a measurement temperature,
It is being respectively provided with one block of heat conductive insulating plate 3 around filament plate 1 upper and lower surface；Cover plate 4 and shell 5 will be around filament plate 1 and heat conductive insulating plate 3 envelopes
Dress is pressed into whole hot table, and to reduce the pollution of dust-like volatile substances, the thickness of whole hot table is less than 5mm.Electrical heating
During plate electrified regulation, the heat energy on resistance wire 2 is delivered on the cover plate 4 and shell 5 of heating plate by heat conductive insulating plate 3, then will
Even heat is radiated on the device needing heating.
