Abstract

The utility model discloses a thermal insulating board, wherein, a plurality of lined bulges (2) are punched on both sides of a aluminum board (1); dents (3) are positioned at the opposite side of the bulges (2); the presence of bulges (2) enlarge the heat radiating area of the aluminum board (1), thereby improving the heat insulation effect; the bulges (2) improves the structure strength of the aluminum insulating board (1), thereby advantageously reinforcing the shaping effect when being applied on the equipment. Additionally, a plurality of sound absorption holes (4) can be provided on the aluminum board (1) to isolate and reduce noises. The utility model can be single-layer, double-layer or multiple-layer structures according to actual demands.

Description

A kind of cleading

Technical field

The utility model relates to a kind of cleading.

Background technology

Cleading is mainly used in and produces sound and heat mechanically, for example on automotive engine or the freeing pipe, also have on other heating, the sonorific equipment, general its surface of existing cleading is smooth, overlay on when using on the heat-producing device at cleading, effect of heat insulation is relatively poor, and the structural strength of sheet material is not high yet.

The utility model content

The purpose of this utility model is to solve smooth cleading poor effect, the problem that structural strength is not high, and a kind of good heat-insulation effect, cleading that structural strength is high are provided.

The utility model is in the punching press of the two sides of sheet metal or foil a plurality of arrangement convex closures to be arranged, the another side that convex closure is relative is depression, the formation of convex closure makes this cleading increase dissipating area, thereby improved effect of heat insulation, the formation of this convex closure has improved the structural strength of sheet material, thus the molding effect when helping on the equipment of being overlying on.

The utility model also can be offered the sound-absorption hole of plural number on sheet material, can play the effect of sound insulation, noise reduction, but the utility model individual layer uses, also can bilayer and multiple layer combination use, described sheet metal is generally selected aluminium for use when actual selecting for use, because aluminium material surface has higher heat reflection performance, material is light simultaneously, meets current mechanical equipment weight-saving developing direction.

Description of drawings

Fig. 1 is the plan sketch of the utility model embodiment.

Fig. 2 is that A-A among Fig. 1 is to amplifying cross-sectional schematic.

The specific embodiment

See also Fig. 1, shown in Figure 2, present embodiment is the convex closure 2 that a plurality of arrangements are arranged in the punching press of the two sides of aluminium plate 1, convex closure 2 relative another sides are depression 3, the formation of convex closure 2, make this aluminium matter cleading increase dissipating area, thereby improved effect of heat insulation, the formation of this convex closure 2 has improved the structural strength of aluminium plate 1, thus the molding effect when helping on the equipment of being overlying on.

In addition, the utility model can be offered the sound-absorption hole 4 of plural number on aluminium plate 1, as shown in Figure 2, can play the effect of sound insulation, noise reduction, the utility model can use according to actual conditions individual layer, bilayer or multiple layer combination, and present embodiment is selected the aluminium plate for use, because aluminium material surface has higher heat reflection performance, material is light simultaneously, is difficult for getting rusty, and meets current structural establishment weight-saving developing direction.

Claims

1. a cleading is characterized in that; In the punching press of the two sides of sheet metal or foil the convex closure of a plurality of arrangements is arranged, the another side that convex closure is relative is depression.

2. according to the described a kind of cleading of claim 1, it is characterized in that; Offer sound-absorption hole on described sheet metal or the foil.

3. according to the described a kind of cleading of claim 1, it is characterized in that; Described sheet metal or foil are aluminium plate or aluminium foil.
