Abstract
The utility model discloses a high-temperature far-infrared directional radiator with a vacuum thermal-protective coating, which is composed of a shell, a heating source, a reflector, a radiant plate with a protective plate, and a thermal-protective layer. The utility model is characterized in that the shell is provided with a hollow airtight cavity body, the vacuum of which is pumped. Compared with the prior art, the radiator increases effective radiation and decreases noneffective radiation at the periphery of the radiator.
Description
The utility model relates to a kind of high temperature far infrared directive radiator, more specifically, relates to a kind of high temperature far infrared directive radiator with vacuum heat-insulating layer.
High temperature far infrared directive radiator is to use high temperature to excite element to produce the heat radiation device of far infrared radiation as pyrotoxin.Install thermal-radiating efficient in order to improve this, the solution that the applicant proposes in No. 98247911.5 applications of submitting on December 2nd, 1998 is to improve its directed radiation except that the reflecting layer is set below the radiation source of radiator, be provided with the plate that plays reflex thereon, make partly not by the reflection by reflecting plate of the energy of radiation direction directed radiation to make it along the radiation direction radiation along radiation direction.The applicant in No. 98247911.5 application also the downside in the reflecting layer be provided with an air layer and reduce idle radiation.Though taked above-mentioned measure that effective radiation of radiator is improved significantly, but, also there is weak point in it, the actual measurement proof, temperature on the directed radiation direction of radiator can reach more than 1000 ℃, but the temperature of irradiator periphery is still up to 200 ℃, and this explanation radiator also needs further to improve its effective radiation efficiency.
Therefore, the purpose of this utility model is to provide a kind of high temperature far infrared directive radiator with vacuum heat-insulating layer of novelty, and this radiator can overcome the defective of prior art, to obtain effectively radiation efficiently.
The shell that comprises a hollow according to the high temperature far infrared directive radiator with vacuum heat-insulating layer of the present utility model, a pyrotoxin is housed in the shell, described pyrotoxin is made up of one or more far infrared heating devices, it below the pyrotoxin reflecting layer, the effect in reflecting layer is the energy of not direct radiation is used by the reflection of surface, reflecting layer, to increase radiation efficiency.Radiant panel with backplate is arranged at the top of pyrotoxin, radiant panel bear most of by the direct radiation of pyrotoxin energy and through the directionally radiation of emittance of reflective layer reflects, that is along the axially upwards radiation (Fig. 1) of radiator.The effect of backplate is part is made it by predetermined direction radiation through the reflection of its one or many without radiant panel directed radiation energy, to reduce the loss of emittance, improves the radiation efficiency of far infrared radiation directive radiator.
Have heat-insulation layer around the radiant panel of pyrotoxin, reflecting layer and band backplate and between the shell, heat-insulation layer is to make with the material of low heat transfer coefficient, for example foamed plastics.In addition, between reflecting layer and shell, also has a air gap layer.
The high temperature far infrared directive radiator of tool vacuum heat-insulating layer of the present utility model is characterised in that described shell is the airtight cavity of a hollow that vacuumizes, this cavity is vacuumizing the back hermetic seal, thereby form a vacuum heat-insulating layer, obviously it applies for that at No. 98247911.5 disclosed device has better heat-proof quality than the applicant.
Above-mentioned purpose of the present utility model and other purpose and advantage thereof will be more readily apparent from by the detailed description below in conjunction with embodiment shown in the accompanying drawing, and accompanying drawing has:
Fig. 1 is the cutaway view according to the high temperature far infrared directive radiator of tool vacuum heat-insulating layer of the present utility model.
As shown in Figure 1, the shell 1 that comprises a hollow according to the high temperature far infrared directive radiator of tool vacuum heat-insulating layer of the present utility model, pyrotoxin 4 is housed in the shell 1, pyrotoxin 4 can be the quartz glass infrared radiation heater, also can be that Chinese patent ZL 94245689.0 disclosed high temperature excite element, the far infrared light wavelength of their radiation be more than 1 μ.Reflector 5 is housed below the pyrotoxin 4, the heat that pyrotoxin 4 radiation produce is along its length side's radial radiation, therefore, only some energy is towards directed radiation (as upwards radiation among the figure), and radiation is to make it towards the orientation direction radiation by reflector 5 reflections on all the other directions, to make full use of the energy of heating element 4 radiation, therefore, the reflector shape of reflector 5 is put to death in the shape of heating element 4, also puts to death in the subtended angle of the directed radiation of high temperature far infrared radiator on the other hand.Reflector 5 can be with stainless steel or resistant to elevated temperatures aluminium alloy manufacturing.
By pyrotoxin 4 directly upwards the energy of radiation and after reflector 5 reflections towards the energy of directed radiation through being positioned at radiant panel 2 directed radiations of pyrotoxin 4 tops, radiant panel is made with quartz material, the periphery design of radiant panel 2 has backplate 3, the effect of backplate 3 is similar to reflector 5, it makes the energy of not directed radiation be pooled to orientation direction, to reduce this partial loss, improve the efficient of whole device.Backplate 3 can use stainless steel, and aluminium alloy and so on material is made, and also can make with the quartz material that applies reflecting material.Backplate 3 can be made of one with radiant panel 2.
Be a heat-insulation layer 6 of being made by the warming plate material below the reflector 5, its role is to make the heat of penetration device 5 radiation unlikely along non-service orientation diffusion, to improve the reflection efficiency of reflector 5, heat-insulation layer 6 generally can be made with foamed plastics.As an embodiment, also can be at the back side of reflector 5 coated heat-insulation layer.
The air barrier of forming between the following inwall by and shell 1 of heat-insulation layer 7 because the thermal conductivity factor of air is low, therefore, has guaranteed the insulation effect of heat-insulation layer 6.
Described pyrotoxin 4, reflector 5, radiant panel 2 and expansion plate 3, heat-insulation layer 6, and also have insulation material 8 between the inwall of the periphery of air barrier 7 and shell.
Now, further specify shell 1 more back, as previously mentioned, shell 1 is a hollow housing, and it can use aluminium alloy, and stainless steel and other suitable material are made, and also can make with organic material, for example ABS etc.Its shape can be rectangular, also can be columniform, or other suitable shape.Shell 1 is hermetic seal, vacuumizes after shaping, forms the hollow cavity 9 of vacuum.The degree that vacuumizes depends on the hollow volume of permissible temperature of desired enclosure and shell 1, and general vacuum is 10
-1To 10
-3, after vacuumizing shell 1 is realized hermetic seal by seal 10.
The applicant is described in detail with regard to design of the present utility model and embodiment; the professional and technical personnel can make various improvement and conversion in view of the above; but these improve and conversion does not all break away from spirit of the present utility model, all within the protection domain that appended claims limits.
