PROBLEM TO BE SOLVED: To provide a method of manufacturing a heat sink, which reduces the number of processes and the like, reduces production processing cost and at the same time, reduces also the labor hour of a work. SOLUTION: In this manufacturing method, a frame wall body 7 with a recessed section, a plurality of sheets of corrugated sheets 8, flat plates 9, a flat cap body 10 and the like are first prepared and at the same time, bonding materials R, such as a bonding agent or a brazing agent, are provided at abutment and bonding places between these of the sheets 8 and the plates 9 in after the preparation. Then, the plurality of sheets of the corrugated sheets 8 and the plates 8 are laminated and filled in the body 7 to form a honeycomb structure, which consists of a planar assembled body constituted of hollow pillar-shaped cells 13, and at the same time, the cap body 10 is made to cover on the body 7 along the axial directions of the cells while being made contact with this honeycomb structure. After that, this body 7, the sheets 8, the plates 9 and the cap body 10 are bonded together at one time with the materials R by heating and a heat sink 6 is obtained. In the sink 6, an object A to be cooled is arranged on the outside and cooling air is made to pass through the honeycomb structure, whereby the heat dissipation and cooling of the sink is executed. |
