The utility model solves the technical scheme that its technical problem adopts: this integral type heat-pipe radiator comprises heat-pipe radiator body and fan.Be provided with a plurality of radial fin around the heat-pipe radiator body, central part is a heat pipe, and fan is located at the top of heat-pipe radiator body.The seal chamber that this heat pipe is made of column cavity wall, top cover, exhaust tubule, inside is vacuum state; Column cavity wall inner surface is provided with the sinter layer of porous capillary structure, is adsorbed with hydraulic fluid in the sinter layer; The upper end of column cavity wall is provided with top cover, and top cover is provided with the exhaust tubule, and the exhaust tubule is sealing state.Described fan is located at the top of heat-pipe radiator body, forces air to flow through radial fin from top to bottom.
The utility model can be further perfect by following manner:
Be provided with a plurality of radial fin around the heat-pipe radiator body, fin is arc or linear.The profile of heat-pipe radiator body can be cylindrical or cube.
The effect that the utility model is useful is: electronic component directly contacts with the heat pipe bottom, the heat that electronic component is produced conducts fast to heat pipe, heat pipe directly conducts heat gives radial fin, forces air to be downward through fin by the fan that is located at the radiator top heat is dispersed in the surrounding air.Because heat pipe is with the mode heat conduction of evaporation-condensation phase-change heat transfer, its heat conduction speed is fast, heat transfer power is big, temperature is even up and down for the heat-pipe radiator body, and the radiating efficiency of fin improves.Heat pipe and radiator body are done together, have eliminated the contact heat resistance between prior art cylinder and radiator body, have improved the efficient and the ability of radiator; Along a plurality of fin that heat pipe outwards distributes radially, area of dissipation is big, and fan places the radiator top, forces air to blow over fin from top to bottom, and wind resistance is little.Therefore this utility model heat-sinking capability is big, thermal resistance is little, in light weight, can satisfy that electronic component is big to radiator power, volume is little, lightweight demand.
