Description
Technical field
The utility model relates to electronic component radiator, specifically a kind of graphite heat radiator.
Background technology
Because electronic component can produce heat energy when consuming electric power, the time that electronic component uses is long more, and the heat of generation will be many more.Electronic component has its normal operating temperature range, if the temperature of electronic component itself exceeds this operating temperature range, the running result of electronic component just may make a mistake.Therefore, electronic component adopts good radiator structure to seem very important.Heat pipe is a kind of element that improves heat transfer efficiency, when heat pipe one end in contact electronic component is heated, absorbs heat from thermal source, and a large amount of heats are delivered to radiating area from the thermal source district.Heat can not piled up at heating position, but be dispersed into equably on the heat radiation thin slice group of radiator.In the prior art, the heat radiation thin slice often adopts copper or aluminium, be further to improve radiating effect, also has to adopt graphite material.Graphite material is a kind of novel heat-conducting medium material, and its planar conductive coefficient is about three times of a fine aluminium conductive coefficient at 500-600W/m.k, and light weight, is the good material that is fit to very much utilization in the heat radiation.But it is soft partially that drawback is exactly a graphite, can not satisfy the technological requirement of carrying out random bending and flange as copper, aluminium, has very strong auxiliary connection technology so connect in the heat radiation practicality.Its many employing resinae welding between thin slice cut sides and heat absorption base plate.But its profile is not attractive in appearance, and producting process difficulty is bigger, and the weld part between thin slice cut sides and heat absorption base plate influences heat-conducting effect.
The utility model content,
Technical problem to be solved: the utility model provides a kind of production technology simple for overcoming the prior art deficiency, and syndeton is scientific and reasonable, the graphite heat radiator of good heat dissipation effect.
Technical scheme: a kind of graphite heat radiator of the utility model, comprise the heat absorption base plate, graphite flake, its special character is: heat pipe is fixed on the heat absorption base plate, some auxiliary fitted component with through hole are set on the heat pipe, also be provided with the graphite flake with through hole and be set on the heat pipe between two adjacent auxiliary fitted component.
The utility model is all right:
Described auxiliary fitted component is circle or polygon Heat Conduction Material thin slice.
Described auxiliary fitted component is the circular foil member through flanging technology.
Described auxiliary fitted component through hole is circular hole, cydariform hole or polygon hole.
Described auxiliary fitted component is two and plural conjoined structure.
The utility model advantage is:
The utility model graphite flake has solved the graphite application limit by being connected between auxiliary fitted component and the heat pipe, also makes it be transferred to the middle part heat absorption from the side heat absorption, and the while also allows graphite flake bring into play more important role in solid space.The utility model is owing to adopt technique scheme, in the integral body assembling, graphite flake is in own and heat pipe close-fitting, the auxiliary fitted component of each employing of both sides clamps up and down, the thin slice that the material that prevents graphite flake oneself is crossed soft generation not just, loosening, distortion etc. are bad, simultaneously, stay the thin slice of heat radiation and the gap between thin slice for graphite flake.The close-fitting contact-making surface that auxiliary fitted component and heat pipe are bigger has increased the heat absorption function, heat is drawn in the auxiliary fitted component be conducted on the thin slice of graphite again, further strengthens thermal conductance and plays a role.It is simple in structure for the utility model, and good heat dissipation effect can be applicable to computer, LED lamp decoration, other electrical type heat radiation such as display floater.
