Heat sink and method for manufacturing heat sink |
摘要 |
This heat sink has bonded on one surface a member to be bonded, and has a cooling member in contact with the other surface. The heat sink is provided with a metal plate having a thermal expansion coefficient larger than that of the member to be bonded, and the metal plate is provided with a center portion where the member to be bonded is bonded, and a plurality of linear peripheral slits formed in a whirl-like radial manner such that the linear peripheral slits surround the center portion. |

1. A heat sink having a surface which is to be bonded to a member to be bonded, the heat sink comprising:
a metal plate having a thermal expansion coefficient larger than that of the member to be bonded, and buried metals; wherein the metal plate is provided with a center portion where the member to be bonded is bonded and a plurality of linear peripheral slits formed in a whirl-like radial manner and in such a way as to surround the center portion, the buried metals are buried in the plurality of linear peripheral slits, and the buried metals are plastically deformed by a shearing stress along the peripheral slits easily as compared with the metal plate. |
