Description

Heat abstractor

Technical field

The utility model relates to electronic component radiator, specifically a kind of heat-pipe radiating apparatus that has honeycomb heat conduction cover on heat pipe

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, general radiator structure has vertical heat radiation, horizontal heat radiation, two ends heat radiation and the heat radiation of other structure, heat pipe all is close-fitting or passes through bond pattern with heat radiation thin slice group connected mode, and the heat radiation thin slice is directly to contact with heat pipe, and heat pipe all can adopt local technology bending or integrally bending.Its deficiency is that general heat pipe radiator structure heat pipe basically all is that the part bending is arranged in suction or heat radiation position, can increase the thermal conductance loss like this, and radiating effect is reduced.

The utility model content

Technical problem to be solved: the utility model provides a kind of heat abstractor that has honeycomb heat conduction cover on heat pipe for overcoming the prior art deficiency.

Technical scheme: a kind of heat abstractor, comprise heat pipe, heat radiation thin slice group, fan is with honeycomb heat conduction cover on described heat pipe, connect heat radiation thin slice group in honeycomb heat conduction cover periphery, and fan outlet is located at heat radiation thin slice group upper end.

Described honeycomb heat conduction cover is solid or hollow-core construction.Described honeycomb heat conduction cover is axially established several heat pipe trepannings.

The advantage of the utility model contrast prior art is:

The utility model is owing to adopt technique scheme, and the heat pipe for thermal conductivity heat is conducted into honeycomb heat conduction cover and imports to heat radiation thin slice group again, and top fan utilizes blast that cold wind is blown into respectively to dispel the heat to dispel the heat between the thin slice, again wind is directly pressed to the thermal source circuit board.Other electron component on thermal source circuit board and the circuit board thereof is dispelled the heat, make its wind direction directly blow to the thermal source area, reduce the temperature of other heat-generating electronic elements around the thermal source and reach the total system cooling-down effect.Solving the general heat pipe structure generally can not multi-faceted deficiency to thermal source district circuit board and electronic element radiating.

The utility model makes heat pipe can not have bending and directly dispels the heat after adopting honeycomb heat conduction cover, heat is centered at heat conduction honeycomb cover forwards the heat radiation thin slice again to and dispel the heat, and can reduce the thermal loss of heat pipe in the technology bending.It is simple in structure, good heat dissipation effect.
