The heat-pipe radiator base comprises a heat dissipation base and metal heat-conduction pipes connected with the heat dissipation base, wherein the heat dissipation base is provided with a metal heat-conduction pipe containing groove. The metal heat-conduction pipes are rolled and molded by at least 2 rollers to form a contact surface for tightly combining with the metal heat-conduction pipe groove and a heat-dissipation contact surface height of which is same to height of an upper surface of the heat dissipation base. By adopting the radiator provided by the utility model, multi-rolling small-variable flexible rolling combination needs relatively small external force and energy can be saved. Deformation of the metal heat-conduction pipes is relatively small in every rolling and molding. Damage of the metal heat-conduction pipes can't appeal generally. Contact surface junction of the metal heat-conduction pipes and the heat dissipation base is very tight and heat dissipation efficiency is raised.

Embodiment

Below the utility model is described in further detail:

See Fig. 1 and shown in Figure 9, the disclosed a kind of heat pipe radiator base of the utility model, it comprise cooling base 2 and with cooling base 2 metal heat-conducting tube 3 that links together, be provided with fin 1, loose with fin 1 and cooling base 2 metal heat-conducting tube 3 that links together at cooling base 2, metal heat-conducting tube 3 can adopt aluminum pipe, copper pipe and compo pipe.Be provided with accommodating metal heat-conducting tube seat at cooling base 2, described metal heat-conducting tube 3 is by forming the heat radiation contact-making surface that contact-making surface reaches and cooling base 2 upper level are smooth that metal heat-conducting tube 3 grooves are combined closely through 2 running roller roll-formings at least.

Described cooling base 2 and metal heat-conducting the tube seat in the same way upper surface in cross section are curved.When the radiator installation needed on the heat radiation chip, when the clamping frame was installed radiator and chip pressing clamping, the radiator end positions produced small distortion, because the upper surface of cooling base of the present utility model is curved, behind the installation of heat radiator, on the contrary and contact-making surface larger, contact tightr.

As shown in Figure 8, the manufacture method of heat pipe radiator base, its concrete steps are as follows:
