Abstract
The utility model discloses a heat-dissipation resistor with an aluminium shell, comprising a resistance wire, mica sheets, a resistor shell, a lead, a bracket and an insulating sizing, wherein the resistance wire is wound on the mica sheets and welded with the lead; the mica sheets are uniformly arranged at the periphery of the inner wall of the resistor shell; the insulating sizing is filled in the resistor shell and used for fixing the mica sheets winding the resistance wire; the resistor shell is provided with a radiating fin; the bracket is connected with the resistor shell; the lead is made from a refractory glass fiber silica gel; and lead clamping grooves for the refractory glass fiber silica gel lead to pass through are arranged at two sides of the resistor. Compared with the prior art, the heat-dissipation resistor with the aluminium shell has the advantages that the breakage phenomenon of the resistance wire due to oxidization are greatly decreased, the service life of the resistor is prolonged; as the unique structure of the radiating fin has good dehumidification effect, the materials are saved and the cost is reduced; and a wiring end can be connected with a power supply in the drying position of the environment, thus being not easy to generate phenomena of contact due to oxidization, and the like.
Description
Technical field
The utility model relates to a kind of heat sink resistance device, especially relates to aluminium shell heat sink resistance device.
Background technology
Go moist firing equipment to be mainly resistance heater.Be exactly that alloy resistance wire with the certain specification model is on mica sheet, pack in the heat radiating metal shell, generally all use aluminum alloy casing, be that fixedly heating resistance wire is closely filled insulated heat-conducting medium in aluminum alloy casing, utilize the principle of resistor heating power to remove wet gas, in the prior art resistor in use binding post vicinity resistance wire in wet environment, use for a long time, be very easy to take place oxidation, often rupture, cause resistor to open circuit, and resistance wire opens circuit, and the back is very difficult to be connected with binding post again, owing to can not elongate after the resistance wire fracture, causes resistor can not continue to use like this, external power cord also adopts binding post to connect in addition, in wet environment, use for a long time and also oxidation can take place, the loose contact phenomenon occurs, normally steady operation, the fin cross section is a rectangle, appearance is a smooth structure, and this structure has increased the use amount of alloy shell material, also is unfavorable for the heat radiation dehumidifying; Inner coiling adopts porcelain spare skeleton to do support, adjusts resistance and lacks flexibility with processing.
The utility model content
The purpose of this utility model is exactly to provide a kind of better aluminium shell heat sink resistance device of resistance wire fracture heat dispersion that reduces for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of aluminium shell heat sink resistance device; comprise resistance wire; mica sheet; resistor housing; lead; support; insulation paste; resistance wire is on mica sheet; resistance wire and wire bonds; be equipped with mica sheet around the resistor housing inwall; insulation paste is filled in resistor housing inside; in order to fixing mica sheet around resistance wire; resistor housing is provided with fin; support is connected with resistor housing; described lead is a refractory glass fibre silica gel lead; avoid resistance wire and wire head to expose in humid air and work, fine resistance wire and the external power supply wire terminal of having protected resistor, described resistor both sides are provided with the lead draw-in groove that penetrates for refractory glass fibre silica gel lead; increase the lead steadiness; the cross section of described fin is a triangle, and this structure is that rectangular smooth cross section is more conducive to heat radiation than cross section, and the resistor housing periphery is provided with mat; mat is connected with resistor housing by screw, and avoiding in use, personnel scald.
Compared with prior art, the utility model makes resistance wire be in work under complete 100% air-proof condition, avoiding the part resistance wire to expose in humid air works, significantly reduce resistance wire oxidation scission phenomenon, prolonged resistor useful life, the utility model is because fin unique texture effect on moisture extraction is good, economical with materials, reduce cost, the utility model can be connected at the environmental drying place terminals with power supply, be not easy to occur phenomenons such as oxidation contact, this design makes resistor be convenient to very much install in addition, and safe in utilization.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As figure; aluminium shell heat sink resistance device; comprise resistance wire; mica sheet; resistor housing 1; lead; support 2; insulation paste 3; resistance wire is on mica sheet; resistance wire and wire bonds; be equipped with mica sheet around the resistor housing inwall; insulation paste 3 is filled in resistor housing 1 inside; in order to fixing mica sheet around resistance wire; resistor housing is provided with fin; support 2 is connected with resistor housing 1, and described lead is a refractory glass fibre silica gel lead 4, avoids resistance wire and wire head to expose in humid air and works; fine resistance wire and the external power supply wire terminal of having protected resistor; described resistor both sides are provided with the lead draw-in groove 5 that penetrates for refractory glass fibre silica gel lead 4, increase the lead steadiness, and the cross section of described fin 6 is a triangle; this structure is that rectangular smooth cross section is more conducive to heat radiation than cross section; the resistor housing periphery is provided with mat, and mat is connected with resistor housing by screw, and avoiding in use, personnel scald.
With the resistance wire of certain model and consumption on the mica sheet of good heat conductivity and insulation, using mica sheet to do winding bracket is because mica sheet processing and coiling adjustment resistance value ratio porcelain spare skeleton are easy, refractory glass fibre silica gel lead 4 welding with the resistance wire that winds and certain-length, in the good aluminum alloy casing of the silica gel sealing of packing into then, in order to guarantee heat radiation and insulation, mica sheet is housed around the aluminum alloy casing inside, fill with the insulation paste medium-tight of specific guide good in thermal property then, in order to fixing aluminum alloy casing inside around the mica sheet of resistance wire, oven dry then also seals the lead draw-in groove together with silica gel at last.
