Description
The utility model relates to a kind of tubular electric heating of making heater with resistance wire.
At present, the electric heater that produce to use has various ways, and by the heater element branch: electrothermal ceramic plate, PCT heating plate, electric infrared heater, resistance wire heating element etc. are arranged, and the most frequently used still is the resistance wire heating element.The electric heater of making of resistance wire has pipe heater and plate-like electric heater, for pipe heater, its version mainly contains two kinds, a kind of is that resistance wire is wrapped on the insulating rod, then it is inserted in to be fixed in the insulated tube and constitutes pipe heater, the disadvantage of this pipe heater is: resistance wire is wrapped on the smooth insulating rod, when the resistance wire heating power, it is more loose to become, particularly when vertical the use, resistance wire will be under the effect of deadweight, landing downwards in case adjacent resistance wire comes in contact, will be short-circuited, the lighter will reduce heating effect, and weight person will produce danger.Another kind of pipe heater is that resistance wire is placed the soft insulating material, and then this electric heating element is installed in the metal tube, and metal tube is fixed formation metal pipe type electric heater through carrying out undergauge.The deficiency of this metal pipe type electric heating element is: the encapsulant between the resistance wire generally is difficult to be filled with evenly, heating repeatedly through resistance wire, resistance wire will produce and expand with heat and contract with cold, resistance wire will make the insulating material between them be shifted through expanding with heat and contract with cold repeatedly, cause resistance wire with being short-circuited, the lighter influences the heating effect of resistance wire, and weight person will cause danger.Moreover, although the metal tube of electrothermal tube outside generally all adopts stainless steel tube,, also can produce corrosion and damage through heat repeatedly.More seriously be that this metal tube can not must be placed in the medium of heating by dry combustion method, otherwise will cause danger.No matter be above-mentioned any electrical heating elements, the joint of resistance wire all is to stretch out from the two ends of outer tube.Some special needs is difficult to satisfy.
The purpose of this utility model is to provide that a kind of heating effect is good, the electric heater of long service life.
The utility model is to realize like this.Its structure is that the front end at a resistant to elevated temperatures insulating joint has a resistant to elevated temperatures insulating rod, have helicla flute on this insulating rod, heating resistance wire just is wrapped in this helicla flute, be set with a resistant to elevated temperatures insulated tube in the outside of insulating rod, the external port of insulated tube is fixedlyed connected with insulating joint, is installed with electric plug in the rear end of insulating joint and constitutes.
Because the said electric heater of the utility model is that heating resistance wire is wrapped on the resistant to elevated temperatures spiral insulating rod, make the accurate positioning of heating resistance wire on insulating rod, can on insulating rod, not produce the short circuit that comes off and cause because of expanding with heat and contract with cold of heating resistance wire makes heating wire, and reduce its heating effect, can guarantee the result of use of electrothermal tube so well.Use the screw-type insulating rod will make that the structure of this pipe heater is more reasonable.Also can prolong widely the useful life of electric heater.The results showed: be generally 3000 hours the useful life that outside is the electric heater of metal tube, and the electric heater made from the structure under the utility model, the heat-resistant insulation tube of its outside suit adopts quartz ampoule, and can reach 5000-8000 hour its useful life.
Fig. 1 is a structure principle chart of the present utility model;
Fig. 2 is a right view of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
The said electric heater of the utility model is the heater that a kind of heating resistance wire is made, its structure is that the front end at a resistant to elevated temperatures insulating joint 5 has a resistant to elevated temperatures insulating rod 3, insulating joint 5 can be fixedlyed connected with insulating rod 3, also can be connected by an alignment pin 4.Have helicla flute on the insulating rod 3, heating resistance wire 1 just is wrapped in this helicla flute, be set with a resistant to elevated temperatures insulated tube 2 in the outside of this insulating rod, the external port of insulated tube 2 is fixedlyed connected with insulating joint 5, and be installed with electric plug 6 in the rear end of insulating joint 5, so that be connected with power supply.Said insulating rod 3 of the utility model and insulating joint 5 preferably adopt resistant to elevated temperatures ceramic material manufacturing.And insulated tube 2 preferably adopts resistant to elevated temperatures quartz ampoule manufacturing, and it not only can produce heat conduction, and can produce thermal radiation, to improve heat transfer efficiency.
The surperficial selected helicla flute of the said insulating rod 3 of the utility model can be the single head helicla flute, also can select the twin-feed spiral groove for use.
The through-hole pipe that the said insulated tube 2 of the utility model can adopt two ends all to communicate, also can adopt the blind hole pipe, for the insulating rod 3 that has the twin-feed spiral groove, if insulated tube 2 adopts the blind hole pipe, the pars intermedia of heating resistance wire 1 is stuck in an end of insulating rod 3, with heating resistance wire 1 separated into two parts, it is wrapped in respectively in the helicla flute, so just can guarantee of the end output of two joints of heating resistance wire from insulated tube 2.If insulating rod 3 adopts the single head helicla flute, for two joints that guarantee heating resistance wire 1 are exported from an end, at this moment, establish an axially extending bore in the center of insulating rod 3, the other end that makes heating resistance wire 1 returns with an electric plug 6 that insulate on 5 through the through hole of adiabatic rod 3 fixedlys connected.This tube electric heater can realize that the terminals double end of heating resistance wire 1 singly goes out, and can realize easily also that the terminals single head of heating resistance wire 1 is two to go out, and promptly the joint of two heating resistance wires stretches out from an end of insulated tube 2.
