Component package having heat exchanger

Abstract

In an electrical component package (1) provided with a liquid-cooled heat exchanger (20), a main-body plate (1A) of the package and a crowning member (5) that are composed of metal plates are joined together, forming a hollow part (6) therebetween for use as a liquid-cooled heat exchanger in which a working fluid is sealed. A concavity (2) for use in mounting an electrical component (8) to be cooled is formed on the outer surface portion of the main-body plate (1A) of the package disposed opposite to the hollow part (6). An inner surface portion (5a) that faces into the hollow part (6) of the main-body plate (1A) of the package is carved out using a carving tool, whereby fins (3) are formed at a fine pitch on the inner surface portion. Minute channels (4) for moving the working fluid are formed between the fins. A flat electrical component package can [therefore] be provided with a liquid-cooled heat exchanger that has excellent heat-radiating functionality.
