Heater strip, the sunken end face in the heating tank close to sleeve bottom are provided with the mounting hole for being caught in heater strip one end,
The mounting hole cross sectional shape is consistent with the heater strip cross sectional shape.
By using above-mentioned technical proposal, when heater strip is embedded in the heating tank of sleeve surface, first by heater strip
One end is penetrated in mounting hole, and since position hole cross sectional shape is consistent with heater strip cross sectional shape, heater strip one end is fixed；Then lead to
Cross instrument heater strip is completely embedded into heating tank, and the one end of heater strip away from mounting hole is extended heating tank, complete to add
The installation of heated filament；Heater strip one end is fixed in mounting hole, will not be because of temperature distortion and out of heating tank in heating process
Depart from.
Further, described sleeve pipe surface is located at heating tank side and is provided with several cavitys communicated with heating tank, institute
State to be provided with cavity and bonded with heater strip for the solder of fixed heater strip.
By using above-mentioned technical proposal, since heating tank is arranged in a curve way sleeve surface, heater strip is in embedded heating tank
After interior, due to natural resiliency, in heating process, easily depart from from heating groove bottom wall, cause contact area to reduce, heat-transfer effect
It is deteriorated；By setting the cavity communicated with heating tank, solder is solded into cavity, solder is melted with the heater strip in heating tank
Close, since cavity opening is small, internal big, solder is not easily disconnected from, so that effectively heater strip is fixed in heating tank.
Further, the heating slot cross-section is trapezoidal.
By using above-mentioned technical proposal, the aperture area of heating tank is less than the area of bottom wall, so that heater strip is embedding
After entering in heating tank, under the position-limiting action of heating tank, heater strip is not easy to depart from out of heating tank, further fixed heating
Silk, to improve heat-transfer effect.
Further, the heat-conducting daub being bonded with heater strip is provided with the heating tank.
By using above-mentioned technical proposal, since heating slot cross-section is trapezoidal, cause heater strip cannot be with the two of heating tank
Side wall is fully bonded, and by setting heat-conducting daub, is filled the gap in heating tank, is reduced thermal loss；Meanwhile heat conduction
Clay has good thermal conductivity and heat-resisting quantity, adds heat conduction efficiency.
Further, the heater jacket is equipped with heat insulating sleeve.
By using above-mentioned technical proposal, by being arranged heat insulating sleeve in heater surfaces, heater surfaces can be reduced
Heat loss, makes the surface that heater strip is located at outside sleeve distribute heat and is concentrated in heat insulating sleeve, realize insulation and thermal insulation
Effect.
Further, state sleeve surface and recessing groove for passing through heater strip is provided with along its axial direction.
By using above-mentioned technical proposal, recessing groove is used to make to leave certain gap between casing and heat insulating sleeve, with
Make heater strip by making heater strip can extend to jacket exterior；Heater strip is interior through recessing groove so that heater is positioned at resigning
Part at groove is heated, so that heating is more abundant.
Further, the one end of the heating tank away from mounting hole is provided with the gap communicated with recessing groove.
By using above-mentioned technical proposal, by setting the gap communicated with recessing groove, make heater strip directly through gap
Into recessing groove, interference is not produced with thermal sleeve, heater strip can be fitted in heating tank all the time, ensure the stability of heat transfer.
Further, described sleeve pipe material is H62 brass.
By using above-mentioned technical proposal, H62 brass has good mechanical property, has good plasticity and machinability,
In order to process heating tank and mounting hole；Its hardness is relatively low, is easily installed heater strip；In addition, also having good thermal conductivity, increase
Heat transfer efficiency is added.
In conclusion the utility model has the advantages that：
1st, by setting mounting hole, realize and one end of heater strip is fixed, in use, heater strip is not easy to take off
From heating tank；
2nd, by setting cavity, further heater strip is fixed；
3rd, the characteristics of copper sheathing pipe heater is high with heat transference efficiency, and heat loss is small is changed.
