Patent ID: 7900692

Claim:
A component package having a heat exchanger, comprising: a first plate member; a second plate member placed on top of an inner surface portion of the first plate member, the first plate member and the second plate member being metal plates; a heat-exchanging hollow part formed between the first plate member and the second plate member, the hollow part being formed in a sealed state; plate-shaped fins formed integrally at prescribed intervals on the inner surface portion of the first plate member by carving out the inner surface portion which faces into the hollow part, the fins having spaces between the fins that function as channels for circulating a heat-exchanging working fluid; an outer concavity for mounting a component subjected to heat exchange, the outer concavity being formed as a component-mounting part by pressing the first plate member in an out-of-plane direction and being formed on an outer surface portion of the first plate member which is disposed opposite to the inner surface portion of the first plate member; a frame-shaped first flat-surface portion surrounding the inner surface portion of the first plate member, the frame-shaped first flat-surface portion being formed on the first plate member; an inner concavity for forming the hollow part; and a frame-shaped second flat-surface portion for encircling an outer circumference of the concavity formed on the second plate member, the first and second flat-surface portions being joined together, wherein the fins are formed by carving out a convexity that is formed using a press to protrude from the inner surface portion of the first plate member and has a size corresponding to the outer concavity, and the fins are formed in an area of the inner surface portion of the first plate member that is substantially vertically aligned to the outer concavity, portions of the first plate member between the fins and the outer concavity being thinner than the other portions of the first plate member.
