Abstract
The utility model relates to an electric heating device and in particular relates to an electric heating plate device which comprises a metal plate and a heating element. A through hole for holding the heating element is arranged in the metal plate. The heating element comprises an electric heating tube, a resistor wire and a down-out rod; wherein the resistor wire is characterized in that the distance between the loops gradually reduces from the middle part to two ends of the resistor wire, so the loops at two ends are dense and the loops at the middle part are thin. The electric heating plate device has the advantage that the temperature at the working surface is even; and the electric heating plate device is widely applicable in occasions which require plane heating, particularly on various electric heating plane plate vulcanizing machines, and has obvious effect on improving the quality of the vulcanized products.
Description
Technical field
The utility model relates to a kind of electric heater unit, especially a kind of electric boiling plate device.
Background technology
Present electric heater unit, electric boiling plate device particularly, mainly be to constitute by the heating element in metallic plate and the plate, on the metallic plate, following two sides is a heating work face, in use, electric boiling plate is the multilayer setting, be placed with the goods that to heat in the middle of per two electric boiling plates, two of the highest and lowest non-heating work face operated by rotary motion have heat-insulation layer in the electric boiling plate of multilayer setting, therefore, in working order down, on the electric boiling plate, the heat transferred of following working face is to the goods of being heated, convection current in air, radiation seldom, and electric boiling plate around the side contact the convection current in air of its heat with air, radiation is more, make that temperature is lower around the electric boiling plate, this just causes the medium temperature height of electric boiling plate working face, the low situation of temperature all around, and the inhomogeneous of its temperature directly has influence on by the Products Quality of heating.Therefore temperature evenly is to improve one of the key issue of quality of item of being heated on the electric boiling plate working face.
Summary of the invention
The purpose of this utility model provides the good electric boiling plate device of a kind of working face temperature homogeneity.
The technical solution of the utility model is a kind of electric boiling plate device, comprise metallic plate and heating element, has the hole of placing heating element in the metallic plate, its innovative point is: heating element comprises electrothermal tube, resistance wire and eduction rod, its resistance wire turns to and begins from the stage casing to dwindle distance between circle and the circle gradually to two ends, forms close and the structure that the stage casing spacing is thin of two ends spacing.
The hole of placing heating element in the described metallic plate is roughly in one plane an exhausting hole of n center line.Has the heat pipe array of linking up in length and breadth between the heating face of described metallic plate and the heating element.Be fixed with the heat-conducting plate and the heating working plate that fit tightly with it on the heating face of described metallic plate.The eduction rod of described electric heating element stretches out from the side of metallic plate.
The utility model is to rely on the distribution that changes resistance wire from heating element, it is close to make two ends, middle dredging, its density degree is wanted root a tree name electrothermal tube length, the decision of electrothermal tube power, make electrothermal tube two ends temperature higher than middle, pack into behind the metallic plate, can offset electric boiling plate heat radiation all around and guarantee that monoblock electric hot plate working surface temperature is even, simultaneously owing to have the heat pipe array and the better heat-conducting plate of heat conductivility of linking up in length and breadth and the working plate that generates heat further to improve the uniformity of electric boiling plate working face temperature.

Fig. 1 is the structural representation of the utility model electric boiling plate device;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of heating element among Fig. 1;
Fig. 4 is the left view of Fig. 1;
Fig. 5 is the structural representation of another embodiment of the utility model electric boiling plate device.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing is further described the utility model:
Referring to Fig. 1,3,5, a kind of electric boiling plate device, comprise metallic plate 1 and heating element 2, has the hole 1-1 that places heating element 2 in the metallic plate 1, its innovative point is: heating element 2 comprises electrothermal tube 2-1, resistance wire 2-2 and eduction rod 2-3, its resistance wire 2-2 turns to and begins from the stage casing to dwindle distance between circle and the circle gradually to two ends, forms close and the structure that the stage casing spacing is thin of two ends spacing.The heat that this structure makes electrothermal tube 2-1 itself send is not even.Therefore, electrothermal tube 2-1 two ends temperature is higher than middle, behind the threading metallic plate 1, can offset metallic plate 1 heat radiation all around and just make that monoblock electric boiling plate heating face 1-3 temperature is even.
Referring to the hole 1-1 that place heating elements 2 in Fig. 2, the 4 described metallic plates 1 is roughly in one plane an exhausting hole 1-1 of n center line.Has the heat pipe 1-2 array of linking up in length and breadth between the heating face 1-3 of described metallic plate 1 and the heating element 2.The further like this uniformity that improves metallic plate heating surface temperature.
Referring to Fig. 5,, be fixed with the heat-conducting plate 3 and the heating work plate 4 that fit tightly with it on the heating face 1-3 of described metallic plate in order further to eliminate issuable heat conduction inhomogeneities on metal material and the structure.
Referring to Fig. 2,3, the eduction rod 2-3 of described electric heating element 2 stretches out from the side of metallic plate 1.Because the eduction rod at electrothermal tube two has been a fixation, do not generate heat, therefore, electrothermal tube 2-1 is longer when making electrothermal tube, makes eduction rod 2-3 stretch out from the side of metallic plate 1, and the part in the electric boiling plate all is heating part, samming better effects if like this.
Electric boiling plate device of the present utility model can be widely used in the various occasions that need plane heating, particularly is used on the various Electrothermal plate vulcanizers, and effect is very obvious.
