Benefits of technology

[0007]The present invention is to provide a heat sink having juxtaposed heat pipes and a method for manufacturing the same. The respective heat pipes are juxtaposed and adhered to each other, thereby increasing the thermal contact area between the respective heat pipes and an electronic heat-generating source. By this arrangement, the heat-dissipating efficiency of the heat sink is increased greatly.

Problems solved by technology

However, it is an important issue to combine heat pipes with a heat-conducting base to generate a better heat-conducting or heat-dissipating effect.
However, since the heat-conducting coefficient of the dividing strip is much smaller that that of the heat pipe, the resultant heat-conducting efficiency of the whole structure is limited.
On the other hand, since the heat pipes are separated from each other by the dividing strips, if one heat pipe is inactive, the other heat pipes cannot help the inactive heat pipe to conduct the heat.
As a result, the electronic heat-generating source may suffer damage or burn down.

Abstract

The present invention relates to a heat sink having juxtaposed heat pipes and a method for manufacturing the same. The heat sink includes a base, a plurality of heat pipes and a pair of side strips. The base has a surface on which an open trough and an insertion trough on both sides of the open trough are provided. Each heat pipe has an evaporating section. The evaporating sections are juxtaposed in the open trough and adhered to each other. Each evaporating section has a planar surface. The side strips are fixed into the insertion troughs and protrude from the surface of the base. The planar surface of each evaporating section and the outer surface of each side strip are coplanar. By this structure, the thermal contact surface between the heat pipes and electronic heat-generating sources is increased, so that the heat-dissipating efficiency of the heat sink is improved.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat sink, and in particular to a heat sink having juxtaposed heat pipes and a method for manufacturing the same.[0003]2. Description of Prior Art[0004]A heat-conducting module constituted by combining heat pipes with a heat-conducting base, or a heat sink constituted by combining heat-dissipating fins and heat pipes can conduct or dissipate the increasing heat generated by current processors. Thus, such a heat-conducting module or heat sink has replaced the conventional heat-dissipating structure constituted by merely heat-dissipating pieces. However, it is an important issue to combine heat pipes with a heat-conducting base to generate a better heat-conducting or heat-dissipating effect.[0005]The conventional heat-dissipating module includes a heat-conducting block and a plurality of heat pipes. The heat-conducting block is provided with a plurality of grooves parallel to one another...
