Claims10
A heat sink with fins comprising:
- a metal base plate to one side of which surfaces a heat generating element is attached in close contact;
- and
- a group of heat dissipating fins comprising plural heat dissipating fins of thin metal plates made of at least two kinds of materials having different heat conductivity, inserted into each of plural grooves formed on other side of the surfaces of said metal base plate, and then crimped from both directions of the grooves by pressing to deform portions of the metal base plate between said grooves, thus fixed on said metal base plate.
A heat sink with fins comprising:
- groups of heat dissipating fins which comprise at least two groups of heat dissipating fins, which are made of at least two kinds of metals having different heat conductivity, said heat dissipating fins of each group being made of same metal, respectively;
- and
- a metal base plate on which surface portion said groups of heat dissipating fins are densely jointed.
