Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation is not limited to following embodiment.
[embodiment 1]
As illustrated in fig. 1 and 2, board-like electric heater unit, including explosion-proof chamber 1, core 2, square flange 3, end socket 4 are used for be a kind of
It (is not drawn into figure) with heat insulation layer.Core is bolted with explosion-proof chamber, convenient to overhaul and replacement electric boiling plate and cooling fin,
End socket 4 is equipped with gas outlet adapter and flange.
As shown in Figures 3 and 4, core include electric boiling plate 102, cooling fin 106, partition 101, electric boiling plate strip of paper used for sealing 103,
Cooling fin strip of paper used for sealing 104 and cover board 105；After cooling fin 106, partition 101, strip of paper used for sealing and 105 groups of cover board are welded into an entirety, need
Air-tight test and the water pressure test are carried out to each inner passage in core, guarantee the leakproofness and pressure-bearing property of inner passage
Can, it detects the quality of welding and combined type end socket is burn-on, is then put into electric boiling plate in reserved cavity after detection is qualified.
As it can be seen in figures 5 and 6, electric boiling plate 102 includes heating wire 201, alumina ceramic plate 202 and mica sheet 203, it will be electric
On potsherd 202,202 two sides of potsherd are covered with thin mica sheet 203 and are integrally formed 201 disk of heated filament, form electric boiling plate
102；Wherein, two sides is slotted on thick potsherd, and by screw type electric filament disc in the slot of potsherd, potsherd upper end is provided with
The heating wire of slot, side continues disk system through the other side by slot, and for the convenience of wiring and installation, the heating wire that two sides are drawn is not
At one end, by 201 disk of heating wire it is good after, cover thin mica sheet in the two sides of potsherd, fixed with bolt, formed electric boiling plate
