Description

The even infrared directive radiator of hot suspension-wire type

The utility model relates to a kind of infrared ray directive radiator, the particularly even infrared directive radiator of hot suspension-wire type.

Existing infrared directive radiator is below the secondary excitation source pyrotoxin to be housed mostly, this pyrotoxin is contained in the groove of pedestal, pyrotoxin is generally cylindrical screw shape heating wire, by heating wire generate heat and through pedestal with a part of heat reflection to the secondary excitation source, make it give off infrared ray.The shortcoming of this structure is that heating wire is enclosed in the groove of pedestal, is difficult for heat radiation, makes the radiator internal temperature inconsistent, causes radiation inhomogeneous; And local temperature is too high, and heating wire easily blows; Shell in use because the temperature difference of upper and lower part is bigger, yielding, causes the directed radiation weak effect.

The utility model purpose provides a kind of even infrared directive radiator of hot suspension-wire type, and it can prolong the heating wire life-span, keeps all even assurance shell of radiation in use not yielding, keeps even, directed radiation effect.And it is simple in structure, and it is low to manufacture cost.

The utility model is realized by following technical scheme.Should comprise shell 1, secondary excitation source 2, pyrotoxin 3, fire-resistant pedestal 4, heat-conducting plate 5, heat-insulation layer 6 by the even infrared directive radiator of hot suspension-wire type, tabular secondary excitation source 2 is equipped with on top in the shell 1, its below is a pyrotoxin 3, it is arranged in the groove of fire-resistant pedestal 4, in the bottom of this fire-resistant pedestal 4 heat-conducting plate 5, heat-insulation layer 6 is housed successively.When using, during pyrotoxin 3 heating powers, heat-conducting plate that can be by being positioned at fire-resistant pedestal 4 belows 5 conducts heat rapidly, makes fire-resistant pedestal 4 and this radiator internal temperature even, produces even strong radiant energy.This heat-conducting plate can adopt the aluminium sheet of good heat conductivity or copper coin to make.The groove of fire-resistant pedestal 4 is that the bottom has some equally distributed grooves of protruding 10 9, this pyrotoxin 3 is supported on the top of this projection 10, makes for example heating wire of this pyrotoxin 3, is in the suspended state by projection 10 supportings, the heat that helps heating wire distributes, and avoids local overheating.On shell 1, be positioned at an end in secondary excitation source 2, have slit 12, overcome the casing deformation that causes greatly owing to the two end temperature difference about this radiator.

Do with embodiment below and specify.

Fig. 1 is a vertical view of the present utility model,

Fig. 2 is the A-A cutaway view among Fig. 1,

Fig. 3 is the C-C cutaway view Amplified image among Fig. 2,

Fig. 4 is that D among Fig. 1 is to view.

As Fig. 1, shown in 2, comprise shell 1, secondary excitation source 2, pyrotoxin 3, fire-resistant pedestal 4, heat-conducting plate 5, the infrared directive radiator of even hot suspension-wire type of heat-insulation layer 6, quartz plate is selected in its secondary excitation source 2 for use, pyrotoxin 3 is a heating wire, heat-conducting plate 5 is an aluminium sheet, secondary excitation source 2 is housed in shell 1, its below is a pyrotoxin 3, this pyrotoxin 3 is arranged in the some grooves 9 on the fire-resistant pedestal 4, the bottom of this fire-resistant pedestal 4 is equipped with heat-conducting plate 5 successively, heat-insulation layer 6, aluminium sheet 7 is housed below heat-insulation layer 6, has binding post 8 in the bottom of shell 1, with reference to Fig. 3, the bottom of this groove 9 has some equally distributed protruding 10, be placed with this pyrotoxin 3 on the top of this projection 10, this pyrotoxin 3 is suspended, help heat radiation.As Fig. 2, this long l sum of equally distributed protruding 10 is that 1/4 to 1/3 of groove 9 length overalls are best.As Fig. 3, this pyrotoxin 3 is the heating wire of the oval spiral of coiled, compares with the heating wire of round screw thread, can increase the area of dissipation of this heating wire, and the power of heating wire is 3.7-4.4w/cm with the power density that to keep this secondary excitation source be quartz plate 2 ²For good.As Fig. 4, for convenience with the aid of pictures, only show shell 1 among the figure, and each part in the shell 1 is all not shown, is the part of upper and lower side opening at this shell 1, with reference to Fig. 1, wide B is 100 millimeters, and high H is 50 millimeters, and length L is fixed with instructions for use.Be positioned at an end in secondary excitation source 2 on shell 1, have slit 12, the wide b of this slit is that 0.5 millimeter, long a are that 20 millimeters, spacing m are 300 millimeters, has overcome because the distortion that the temperature difference causes more greatly between the top of shell 1 and the bottom.When using, energising is with pyrotoxin 3 heating, and this secondary excitation source 2 promptly gives off infrared ray, can single, a plurality of uses; Arrange arbitrarily, any direction is installed and all can.By the product that present embodiment is made, compare with the product of homogeneous structure, under same power, the heating wire life-span has prolonged one times, and product does not in use have distortion.

In sum, the utility model is owing to adopted oval spiral heating wire, increased the area of dissipation of heating wire, adopt Floating support slot, the heat that helps heating wire distributes, and by heat-conducting plate that the heat distribution on the fire-resistant pedestal is even, causes heat efficiency raising and radiation even, and avoid local overheating, improved the heating wire life-span.Slit in the shell upper end has overcome the distortion that this radiator upper and lower temperature difference causes greatly, keeps the directed radiation function.In addition, this utility model material therefor all can be buied by market, and material is not had specific (special) requirements, and simple in structure, is easy to manufacture, so cost reduces.

The even infrared directive radiator of hot suspension-wire type of the utility model is applicable to the usefulness of printing and dyeing, tobacco, welding rod industry, refrigerator, washing machine, the automobile plastic-blasting oven dry in spraying paint, and the usefulness of food and other industry oven dry.
