Abstract
The invention discloses a heat-dissipation resistor with an aluminum 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 aluminum 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 present invention relates to a kind of heat sink resistance device, especially relate to a kind of aluminium shell heat sink resistance device.
Background technology
Go moist firing equipment to be mainly resistance heater.Be exactly alloy resistance wire with the certain specification model on mica sheet, in the heat radiating metal shell of packing into, generally all use aluminum alloy casing; In aluminum alloy casing, closely fill insulated heat-conducting medium, utilize the principle of resistor heating power to remove wet gas for fixing heating resistance wire, in the prior art resistor in use binding post vicinity resistance wire in wet environment, use for a long time; Be very easy to oxidation takes place, 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, uses for a long time and also oxidation can take place, and poor contact phenomenon occurs; Can not normal and stable work, the fin cross section is a rectangle, appearance is a smooth structure; 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, and the adjustment resistance lacks flexibility with processing.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of better aluminium shell heat sink resistance device of resistance wire fracture heat dispersion that reduces to be provided.
The object of the invention can be realized through following technical scheme:
A kind of aluminium shell heat sink resistance device comprises resistance wire, mica sheet, resistor housing, lead, support, insulation paste, and resistance wire is on mica sheet; Be equipped with mica sheet around resistance wire and the wire bonds, 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, and support is connected with resistor housing; Said lead is a refractory glass fibre silica gel lead, 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; Said resistor both sides are provided with the lead draw-in groove that supplies refractory glass fibre silica gel lead to penetrate, and increase the lead steadiness, and the cross section of said fin 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 through screw, and avoiding in use, personnel scald.
Compared with prior art, the present invention makes resistance wire be in work under complete 100% air-proof condition, avoids the part resistance wire to expose and in humid air, works; Significantly reduce resistance wire oxidation scission phenomenon, prolonged resistor useful life, the present invention is because fin unique texture effect on moisture extraction is good; Economical with materials; Reduce cost, the present invention 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 accompanying drawing and specific embodiment the present invention is elaborated.
Like figure, a kind of aluminium shell heat sink resistance device comprises resistance wire, mica sheet, resistor housing 1, lead, support 2, insulation paste 3; Resistance wire is on mica sheet, and resistance wire and wire bonds are equipped with mica sheet around the resistor housing inwall; Insulation paste 3 is filled in resistor housing 1 inside, and in order to fixing mica sheet around resistance wire, resistor housing is provided with fin; Support 2 is connected with resistor housing 1, and said 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, said resistor both sides are provided with the lead draw-in groove 5 that supplies refractory glass fibre silica gel lead 4 to penetrate, and increase the lead steadiness; The cross section of said fin 6 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 through 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, the refractory glass fibre silica gel lead 4 of the resistance wire that winds and certain-length is welded, 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, then with the insulation paste medium-tight filling of specific guide good in thermal property, 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 with silica gel at last together.
