Description

Hot buffer element
Technical field
The present invention relates to a kind of hot buffer element.
Background technology
The heat dissipation element that is applied at present electronic product is mostly fan, fin, heat pipe or water-cooled device.Yet due to scientific and technological progress, the external form of the electronic products such as notebook computer, panel computer and mobile phone is more and more frivolous, and above-mentioned heat dissipation element is because volume is difficult to dwindle, and has limited the reduction of electronic product integral thickness, therefore can cause the inconvenience in design.
In addition, though can be attached on the thermal source of electronic product with known slim conducting strip or fin, known conducting strip or fin only can, as the medium of heat transmission, only can provide the path of thermal energy transfer, do not have the function of heat energy storage, and be difficult for maintaining the temperature of electronic product.That is to say, known conducting strip or fin are in fact very limited for the equally distributed effect of heat of electronic product, are therefore difficult to provide good experience for user.
Summary of the invention
The invention provides a kind of hot buffer element that is applied to electronic installation, it comprises heat-absorbing material and a plurality of metallic particles.The corresponding setting of thermal source of heat-absorbing material and electronic installation.Metallic particles is dispersed in heat-absorbing material.
Because heat-absorbing material can store the heat energy that thermal source produces, and metallic particles can improve the rate of heat transfer of hot buffer element, therefore when hot buffer element is positioned on thermal source, when being positioned at circuit board back on the surface of thermal source time or being located close on the housing of thermal source, hot buffer element can be by the thermal energy storage of thermal source diffusion, make electronic installation there is equally distributed temperature, avoid causing hot concentration phenomenon at the heat source position of electronic installation.
In addition,, when the temperature acute variation of thermal source, hot buffer element can pass through heat absorption and the heat release of heat-absorbing material, slows down the rate temperature change of electronic installation, is convenient to the heat management of electronic installation integral body.Thus, can not only promote the component life in electronic installation, and when user uses electronic installation, can differently because of the position touching not feel the excessive temperature difference, there is preferably temperature sensation.
