Abstract
The invention provides a heater strip casing pipe. A body made of high-temperature alloy comprises a spiral groove used for fixing a heater strip and an air outlet. Due to the design of the spiral groove, the heating strip can be directly fixed and the problem that the heating strip is difficult to fix is solved; the outlet hole is used for dissipating heat of the heater strip; heat dissipation is conducted on the inner portion through the air outlet with the diameter of 4mm; the surface of the body is coated with a high-temperature-resistant material. Due to the fact that the body is made of the high-temperature alloy and the surface of the body is coated with the high-temperature-resistant material, the service life is prolonged. The designed heater strip casing pipe is simple in structure, the material of the casing pipe is resistant to high temperature, the service life is long, and the casing pipe is not prone to breakage.
Description
Technical field
The invention relates to a kind of heater, particularly a kind of heater strip sleeve pipe.
Background technology
The key that improves the useful life of heater strip is the connectivity problem of realizing between heater strip and sleeve pipe, and in practical operation, the connected mode of heater strip and sleeve pipe has two kinds, and a kind of is to adopt the mode of welding to connect; Another kind is to adopt the mode of glueing joint to connect.But, adopt welding difficulty larger, the node welding under vibration environment is prone to crackle, produces heating wire and contacts bad problem with sleeve pipe, affects heater and uses; If adopted, glued joint, long-time use can cause bonded adhesives to have aging, tired problem, easily causes heating wire to contact bad problem with sleeve pipe, affects heater and uses.
Summary of the invention
The problem that the invention will solve is to provide a kind of heater strip sleeve pipe, has solved a fixedly difficult problem for heater strip, and rapid heat dissipation, has extended the useful life of heating muff.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of heater strip sleeve pipe, and the body that adopts high temperature alloy to prepare comprises:
Helicla flute, for fixing heater strip; Helicla flute design can be directly fixing heater strip, solved the fixedly difficult problem of heater strip;
Venthole, for distributing the heat of heater strip; The venthole of inner utilization φ 4mm carries out the heat radiation of heat;
The surface-coated exotic material of described body, body adopts high temperature alloy and at surface-coated exotic material, improves useful life.
Further, spiral fluted angle is consistent with the angle of heater strip, facilitates being connected or installation between heater strip and sleeve pipe.
Further, body is pipe, and venthole is uniformly distributed along the circumference at body surface.
This heating muff can be widely used in the fields such as Aeronautics and Astronautics, chemical industry, electronics.
Advantage and good effect that the invention has are: this heater strip sleeve surface arranges helical groove structure and is convenient to the fixing of heater strip, the venthole that sleeve surface is uniformly distributed 54 φ 4mm facilitates heater strip to dispel the heat, sleeve pipe adopts high temperature alloy and in surface-coated exotic material, longer service life.The advantage that the invention has is as follows:
(1) high temperature resistant, the long service life of the material simple in structure, sleeve pipe of the heater strip sleeve pipe of the invention design, easy fracture not.
(2) in order to facilitate the installation, fixing of heater strip, a kind of groove consistent with heater strip spiral angle of sleeve surface design, can be fixed in the groove of sleeve pipe heater strip, without welding or bonding mode again.
Accompanying drawing explanation
Fig. 1 is heater strip sleeve structure schematic diagram;
Fig. 2 is provided with the schematic diagram of heater strip on heater strip sleeve pipe.
In figure:
1. venthole 2. helicla flute 3. heater strips
Embodiment
In conjunction with the accompanying drawings and embodiments the technical scheme of the invention is elaborated.
As shown in Figure 1, a kind of heater strip sleeve pipe, body is the pipe that adopts high temperature alloy to prepare, and venthole 1 is uniformly distributed along the circumference at body surface, and body surface is provided with for the fixing helicla flute 2 of heater strip; Venthole 1, for distributing the heat of heater strip; The surface-coated exotic material of described body.The angle of helicla flute 2 is consistent with the angle of heater strip 3.
As shown in Figure 2, by heater strip 3 according to the slow precession sleeve pipe of the direction of the spiral angle of helicla flute on sleeve pipe 2, because the helicla flute 2 of sleeve pipe is identical with the spiral angle of heater strip 3, thus the surface of heater strip 3 can be arranged in the groove of helicla flute 2, without welding again, gluing connection.
Above the embodiment of the invention is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the invention scope and improvement etc., within all should still belonging to this patent covering scope.
