Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model and beneficial effect thereof are described in further detail.

With reference to Fig. 1, a kind of high conduction efficient carbon trichite heat, radiator comprise superconducting layer 6, and a side of this superconducting layer 6 sets gradually first inorganic insulation layer 5, carbon trichite thermosphere 4, second inorganic insulation layer 3, metallic reflector 2 and inorganic insulating layer 1.

The utility model superconducting layer 6 is according to residual gas heat conduction principle, and when the pressure of vacuum chamber was extracted into a certain limit, the heat that gas conducts between heat exchange surface can be ignored.When using the SU304 stainless steel as superconducting layer exterior material, because its physical strength is done 1200 times (thermal conductivity factor of copper is 383.8W/m.K, and namely the thermal conductivity factor of this superconducting layer is 460560W/m.K) that its thermal conductivity factor after the application of vacuum can reach the copper thermal conductivity factor.Simultaneously, because this moment, heat transfer type was that radiant type is conducted heat, radiant type heat transfer energy can not decayed in a vacuum, so this moment, heat energy can at utmost be delivered to material surface down.Concrete preparation method makes gross thickness to the SU304 stainless sheet steel to be no more than the 3CM evacuated panel, perhaps is tiled into one deck with vacuum tube with arrangement arranged side by side and forms the superconducting layer.

Under this structure constituted, because the hot conduction mode of the brilliant material of carbon and vacuum heat-conduction material is the radiant type conduction, the heat exchange pattern that has changed heating, radiator conducted heat with radiant type and replaces convection type to conduct heat.Greatly improve heat conduction velocity, reduced carbon crystal electrothermo device specific heat rejection to greatest extent.

Described first, second inorganic insulation layer 5,3 adopts the insulation splitting, (DCB ceramic substrate Direct Copper Bonding refers to copper and aluminium oxide ceramic substrate or aluminium nitride ceramics substrate Direct Bonding composite together to the DCB ceramic substrate.Have the good electric insulating properties, high thermal conduction characteristic, excellent solderability and high adhesive strength, and can etch various figures as pcb board, have very big current capacity.Therefore, the DCB ceramic substrate has become the basic material of high-power electric and electronic circuit structure technology and interconnection technique.Epoxy resin or PET plastic sheeting that the existing carbon crystal electrothermo device insulating barrier of comparing adopts, the thermal conductivity factor of the inorganic insulating material that the utility model adopts is well below above material, this has just guaranteed that with under the constant power electric heater energy loss that inorganic insulating material sheet of the present utility model is made substrate is lower, programming rate is faster, the heat radiation is more even.

Described inorganic insulating layer 1 adopts inorganic heat insulation materials such as foaming mud warming plate, pearlite heat-insulation plate, littleization of hollow bead heat-insulation layer.It is low to adopt the inorganic heat preservation plate to have a thermal conductivity factor as heat-insulation layer, can reach below 0.050 W/m.K, has reduced the convection type heat radiation in the hot conduction.Long service life, can with the same life-span of concrete construction.Nontoxic, tasteless, "dead" pollution to environment and body harmless, has good environmental protection benefit.Inorganic heat insulation material heat-insulation system fire prevention A level is not burnt.

What existing carbon crystal electrothermo device adopted on the reflecting layer substantially is aluminium-foil paper or ground thermal reflecting coating, these strengths of materials poor (being exactly the intensity of paper substantially).Reflecting effect because the surface of reflectance coating is difficult to guarantee smooth and no breakage to cause reflecting effect poor.Because aluminium-foil paper or ground thermal reflecting coating intermediate materials are paper or other organic materials, so temperature tolerance is poor, burning-point is low, cause that easily material structure Yin Gaowen changes or burns, and brings potential safety hazard to use.Adopt metallic reflective coating such as aluminium, copper, tin buckle as the reflecting layer.The burning-point of metal is higher than the heating temp (90 ℃) of the brilliant heating element of carbon far away.It is better that the back reflection effect is handled in the surface finish of metallic reflective coating, completely cut off the effect that hot crossing radiant type is conducted heat largely.

Because the utility model material therefor is inorganic material, heat-resisting, flame retardant effect is given prominence to, and security of products and stability are high, not gaseous contamination in the generating chamber, and material is recyclable utilization all, meets directional heat conduction, heat conversion height, free of contamination requirement.

Structure of the present utility model can be used on the heating systems such as heating of house equipment, warmhouse booth heating equipment, animal feeding room heating equipment.Because the brilliant heating element of carbon has the effect of infrared treatment, can also make infrared treatment equipment in addition.Under situation about changing by powered by direct current, can be used as portable heating system.
