Abstract

A heat resistant structure with a heat conduction function mainly comprises a sheet-shaped heat resistant layer. A plurality of independent heat resistant spaces are densely uniformly arranged inside the sheet-shaped heat resistant layer. The two side faces of the heat resistant layer respectively have a heat conduction sheet attached thereon. The air between the two heat conduction sheets is pumped out during an assembling process. Each heat resistant space of the heat resistant layer can be isolated from the outside and keep a vacuum state. The heat resistant layer can thus obstruct the passage of the majority of heat. Meanwhile, by means of the heat conduction sheets, a part of heat can be rapidly transmitted and diffused towards the peripheries. Effects of obstructing heat transmission and preventing heat from concentrating on a local position are thus achieved.

Have the heat insulation structure of heat conduction function concurrently

Technical field

The relevant a kind of heat insulation structure that has the heat conduction function concurrently of the utility model, espespecially a kind of effectively trap heat transmission, and avoid the heat concentrations in the heat insulation structure of local location.

Background technology

Traditional electronic installation internal circuit often is difficult to have many heat source bodies (processor, power crystal or other when work, can produce the assembly of heat) with avoiding.This heat source body can produce a large amount of heats when work, if this heat is directly spread, and near local surface of shell position excess Temperature can causing.Therefore, more common ground, to utilize heat transfer efficiency preferably heat-conductive assembly is (for example: heat pipe) with its part, be attached on this thermal source, and on this heat-conductive assembly, separately be equipped with the radiating subassembly that increases radiating effect, utilize this heat-conductive assembly that the heat of thermal source is transferred to other position, dispersed again, can be reduced so that heat is concentrated and the situation that causes the local location excess Temperature.

The direct blocking heat source of thermal resistance assembly that another favourable use has a splendid thermal resistance characteristic conducts to the mode of housing, and this thermal resistance assembly is made to sheet or cap shape, can directly be arranged between thermal source and position to be intercepted, and uses to reach and blocks the effect that heat transmits.

Yet, the mode of above-mentioned application or structure all only have the function of single heat transmission or heat obstruct, but and vertically transmit (blocking the direct radiation transmission of heat) there are no trap heat, by the technological means of the horizontal rapid diffusion of heat (avoiding heat accumulation in local location), cause it in practical application, to be difficult to reach the effect be entirely satisfactory simultaneously.

Because known heat conduction or thermal resistance assembly have above-mentioned shortcoming, creator when application, be the road for those shortcoming Improvements, finally have this creation to produce.

Summary of the invention

The purpose of this utility model is to provide a kind of heat insulation structure that has the heat conduction function concurrently, and it is the direct radiant transfer of trap heat effectively, causes peripheral temperature anomaly to rise with the heat of avoiding thermal source.

Another purpose of the present utility model is to provide a kind of heat insulation structure that has the heat conduction function concurrently, its can be rapidly by heat to the surrounding transfer spreading with disperse, to avoid heat build-up, affect each assembly normal operation.

For reaching above-mentioned purpose and effect, the technical scheme that the utility model adopts is: a kind of heat insulation structure that has the heat conduction function concurrently, be characterized in, it comprises at least: the sheet heat resistant layer of a bad heat conduction, and section evenly is densely covered with several thermal resistance spaces independently separately in the inner; The conducting strip of two splendid thermal conduction characteristics of tool, be attached at respectively two of this heat resistant layer and show sides, makes each thermal resistance space externally form isolation fully.

According to said structure, described heat resistant layer several flexible section ropes of serving as reasons weave the network structure body formed, and this thermal resistance space mesh that is this network structure body.

According to said structure, be penetrated with through hole on described heat resistant layer.

According to said structure, on described heat resistant layer, be laid with spongy porous organization.

According to said structure, described heat resistant layer is provided with groove.

According to said structure, described each thermal resistance interior volume keeps vacuum.

So, this structure is the direct radiant transfer of trap heat effectively, causes peripheral temperature anomaly to rise with the heat of avoiding thermal source; Can be rapidly by heat to the surrounding transfer spreading with disperse, to avoid heat build-up, affect each assembly normal operation.

For above-mentioned purpose of the present utility model, effect and feature can be obtained more specifically, understand, hereby according to following accompanying drawing, be described as follows.
