As fixed part 4, can exemplify screw (screw).
Heated parts 5 is to bear the hot parts that semiconductor device 3 sends.
Heat-conducting part 6 is the heat of heated parts 5 to be passed to the parts of radiating part 7, and possesses cold-producing medium in inside.
Radiating part 7 is parts that the heat of coming via heat-conducting part 6 conduction is emitted.Radiating part 7 does not possess the structure of fin (fin) shape etc., but forms the smooth structure without concavo-convex processing.The radiating part of therefore, constructing with fin is in the past compared and can be reduced to occupy space.
High thermal transfer plate 8a, 8b are the parts that make respectively to conduct in the heat between semiconductor device 3 and heated parts 5 and between radiating part 7 and electric component case 9 become smooth and easy (smooth), and the material of high thermal transfer plate 8a, 8b is the material that pyroconductivity is high.In addition, in the situation that the caloric value of semiconductor device 3 is little, also one or both in high thermal transfer plate 8a, 8b can be set.
As long as electric component case 9 has thermal endurance, corrosion resistance and the mechanical strength of the degree that can tolerate environment for use.
Heated parts 5, heat-conducting part 6 and radiating part 7 form heat pipe, and radiating part 7 is configured in the position higher than heated parts 5.The heat that semiconductor device 3 sends is passed to radiating part 7 from heated parts 5 via heat-conducting part 6, and emits from electric component case 9.
Because radiating part 7 is configured in the position higher than heated parts 5, therefore by the refrigerated medium in the heat pipe after heated parts 5 heating, towards radiating part 7, flowed.Like this, cold-producing medium flows towards radiating part 7 naturally from heated parts 5, does not therefore need the pump (pump) for making refrigerant circulation.
, the power inverter of present embodiment is mounted in the power inverter that one or more semiconductor device 3 on electronic printing substrate 2 are incorporated in electric component case 9, it is characterized in that, this power inverter forms following structure: possess heat pipe, this heat pipe possesses the heated parts 5 of the setting of contacting with semiconductor device 3, contact the heat-conducting part 6 arranging with this heated parts 5 and contact the radiating part 7 arranging with this heat-conducting part 6, the radiating surface of radiating part 7 is along the gabarit configuration of electric component case 9, radiating part 7 is disposed at the position higher than heated parts 5, cold-producing medium in described heat pipe is by gravity and temperature gradient and spontaneously circulation.In addition, radiating surface refers to the face of the area maximum that radiating part 7 has, and is the face with semiconductor device 3 opposition sides.
