Description
Technical Field
The utility model relates to a heat-conducting glue especially relates to a compound heat conduction double faced adhesive tape.
Background
The double-sided adhesive tape is mainly used for heat dissipation of electronic components (such as heat dissipation of a CPU). When the double-sided adhesive tape is bonded between the heat conductive element and the heat sink, bubbles are easily generated in the bonding process, and sometimes cannot be seen by naked eyes. And in the long-time working process of the heat-conducting double-sided adhesive tape, the edges of the heat-conducting double-sided adhesive tape are easy to dry or be polluted, so that the adhesive failure or the pollution is caused. The heat conduction double faced adhesive tape of prior art can't discharge or reduce the bubble to can't improve double faced adhesive tape's coefficient of heat conductivity, thermal conductivity is relatively poor, also can't effectively protect the double faced adhesive tape edge, reduces the double faced adhesive tape edge and dries out or receives the pollution, thereby improves double faced adhesive tape's life. Therefore, the development of a composite double-sided thermal adhesive tape is a problem to be solved by those skilled in the art.

The above object of the present invention is achieved by the following technical solutions: the utility model provides a compound heat conduction double faced adhesive tape, includes concave type copper sheet, concave type copper sheet upper and lower surface all establishes to indent sphere form, and concave type copper sheet upside is equipped with heat-conducting glue layer, and the downside is equipped with down heat-conducting glue layer, be equipped with evenly distributed's a plurality of through-hole between the upper and lower surface of concave type copper sheet, make and go up heat-conducting glue layer and heat-conducting glue layer infiltration these a little through-holes and bond mutually down.
The utility model discloses a theory of operation: firstly, the colloid is extruded into the through holes of the concave copper sheet by the extrusion of the upper layer of heat conducting glue, and after all the through holes emerge from the colloid on the other side of the concave copper sheet, the lower heat conducting glue layer is covered, so that the composite heat conducting double-sided adhesive with the concave copper sheet sandwiched in the middle is manufactured. And the lower heat-conducting adhesive layer is attached to the surface of the heating element, and the lower heat-conducting adhesive layer is formed between the concave copper sheet and the heating element. And then the surface of the radiator is attached to the upper layer of the concave copper sheet, and an upper heat-conducting adhesive layer is formed between the concave copper sheet and the radiator. By extruding the radiator, the upper and lower heat-conducting adhesive layers are stressed and transversely extruded, and the edges of the concave copper sheet can provide an inward gathering force for the upper and lower heat-conducting adhesive layers, so that the pressure between the upper heat-conducting adhesive layer and the lower heat-conducting adhesive layer is increased, and the density is increased. Under the high pressure state, the volumes of the gas in the upper and lower heat-conducting glue layers and the residual gas on the contact surfaces of the upper and lower heat-conducting glue layers, the radiator and the heating element are reduced. The influence on the heat-conducting performance of the upper heat-conducting glue layer and the lower heat-conducting glue layer is reduced after the volume of the gas is reduced, so that the heat conductivity of the double-sided adhesive is improved. The concave copper sheet has wide edges, and can effectively reduce the area of the edges of the upper and lower heat-conducting adhesive layers exposed in the air, thereby reducing the volatilization of moisture in the upper and lower heat-conducting adhesive layers and keeping the viscosity of the double-sided adhesive. The service life of the upper and lower heat-conducting adhesive layers is prolonged.
