Abstract
The utility model discloses an environment-friendly thermal shield, which comprises an upper layer made of an aluminum coated plate, a middle thermal insulating layer made of environment-friendly thermal insulation materials capable of enduring the high temperature above 1000 DEG C, and a lower layer made of another aluminum coated plate. The environment-friendly thermal shield has the advantages of simple structure and tidy appearance, and can effectively avoid the influence to the peripheral non-metallic components by the radiating heat quantity, and play a role of heat preservation.
Description
Technical field
The utility model relates to thermal shield, particularly relates to the environmental protection thermal shield.
Background technique
The tradition thermal shield generally adopts monometallic or bimetal to make, and employing double-level-metal+insulating layer structure is also arranged.Monometallic or bimetal thermal shield are simpler on technology, control is also fine in appearance, but because that the heat of metal is passed process is very fast, the heat one of radiation is that peripheral part is brought adverse effect, the 2nd, because heat radiation is too fast, make that near the exhaust gas temperature the automobile exhaust manifold outlet also correspondingly descends, facilitate bag for the ternary that operating range is arranged, if temperature is lower than its minimum operating temperature, its catalytic conversion effect will be had a greatly reduced quality.Traditional three-decker thermal shield is owing to the factor of its structure and material composition, and traditional preparation process is difficult to stop the generation of fold, in the employing of gas exhaust manifold thermal-protective material, generally selects asbestos or glass wool etc. for use at present.Wherein asbestos protect ring and exist unfavorable factor to be prohibited in the automobile industry use, and its operating temperature also is only applicable to 200 ℃～450 ℃, the high row's temperature of incompatibility motor car engine.And glass wool adaptive temperature (400 ℃～650 ℃) and environmental protection factor all are better than asbestos, but influenced by its adaptive temperature district, are unfavorable for using that to exceed the vent systems of its adaptive temperature scope in row's temperature heat insulation.Therefore present thermal-protective material is chosen improperly, causes and attends to one thing and lose sight of another.
Summary of the invention
The utility model is finished in order to solve deficiency of the prior art, and that the purpose of this utility model provides is simple in structure, flat appearance, can effectively prevent the influence of radiations heat energy to peripheral non-metal part, plays the environmental protection thermal shield of insulation effect simultaneously.
Environmental protection thermal shield of the present utility model comprises the upper strata of being made by alclad sheet, constitutes by the anti-intermediate thermal insulating layer that the environmental protection thermal-protective material of high temperature is made more than 1000 ℃ with by the lower floor that alclad sheet is made.
Environmental protection thermal shield of the present utility model can also be:
Described intermediate thermal insulating layer is by the anti-mesosphere that the refractory ceramic fiber paper of high temperature is made more than 1000 ℃.
Environmental protection thermal shield of the present utility model, in terms of existing technologies: comprise the upper strata of making, by the anti-intermediate thermal insulating layer that the environmental protection thermal-protective material of high temperature is made more than 1000 ℃ and the lower floor of making by alclad sheet by alclad sheet.The advantage of this spline structure is that outer field alclad sheet is easy to process and can not produce fold, flat appearance in stamping process.And the intermediate thermal insulating layer that the environment protection heat-proof material of anti-1000 ℃ of high temperature of intermediate course is made can prevent the influence of radiations heat energy to peripheral metalwork, plays insulation effect simultaneously.

Embodiment
Below in conjunction with accompanying drawing Fig. 1 environmental protection thermal shield of the present utility model is described in further detail.
Environmental protection thermal shield of the present utility model please refer to Fig. 1, comprises the upper strata 1 of being made by alclad sheet, by the anti-intermediate thermal insulating layer 2 that the environmental protection thermal-protective material of high temperature is made more than 1000 ℃ and the lower floor 3 of being made by alclad sheet.The advantage of this spline structure is, upper strata 1 and lower floor 3 are that outer field alclad sheet is easy to process and can not produce fold, flat appearance in stamping process.And the intermediate thermal insulating layer 2 that the environment protection heat-proof material of anti-1000 ℃ of high temperature of therebetween is made can prevent the influence of radiations heat energy to peripheral metalwork, plays insulation effect simultaneously.
Environmental protection thermal shield of the present utility model please refer to Fig. 1, and described intermediate thermal insulating layer is by the anti-mesosphere that the refractory ceramic fiber paper of high temperature is made more than 1000 ℃.Because the Applicable temperature of refractory ceramic fiber paper is 850 ℃-1750 ℃, and is environment-friendly materials, therefore meet the requirements fully.Certainly can also be the refractory material of other anti-1000 ℃ of high temperature.
Above-mentionedly only the specific embodiment of the utility model is illustrated; but can not be as protection domain of the present utility model; every equivalence variation of having done according to the design spirit in the utility model or modification or equal proportion are amplified or are dwindled etc., all should think to fall into protection domain of the present utility model.
Claims (2)
1. environmental protection thermal shield is characterized in that: comprise the upper strata of being made by alclad sheet, by the anti-intermediate thermal insulating layer that the environmental protection thermal-protective material of high temperature is made more than 1000 ℃ and the lower floor of being made by alclad sheet.
2. environmental protection thermal shield according to claim 1 is characterized in that: described intermediate thermal insulating layer is by the anti-mesosphere that the refractory ceramic fiber paper of high temperature is made more than 1000 ℃.
