HEAT DISSIPATION STRUCTURE, POWER MODULE, METHOD FOR MANUFACTURING HEAT DISSIPATION STRUCTURE AND METHOD FOR MANUFACTURING POWER MODULE

摘要

A heat dissipation structure having high joining strength during a cooling/heating cycle and a high cooling efficiency, a power module, a method of manufacturing the heat dissipation structure, and a method of manufacturing the power module is provided. A power module 1 of the present invention includes: a ceramic substrate 10 having an insulation quality; a metal member 50 containing a metal or an alloy and joined by a brazing material on a surface of the ceramic substrate 10; and a heat dissipation member 40 formed by accelerating a powder containing a metal or an alloy with a gas, and by spraying and depositing the powder in a solid phase state on a surface of the metal member 50, wherein a heat pipe 60 is embedded in the heat dissipation member 40.
