Abstract:
According to some embodiments, a cooling device may comprise first and second contact surfaces to transfer heat to a cooling medium. The cooling device may further comprise, in some embodiments, a first electrical component coupled to transmit heat to the first contact surface and a second electrical component coupled to transmit heat to the second contact surface.
Abstract:
Die Erfindung bezieht sich auf eine drahtbeschriebene Leiterplatte oder Platine mit sich auf und/oder in der Leiterplatte oder Platine zwischen Anschlussstellen erstreckenden Leitungsdrähten. Um derartige Leiterplatten zu verbessern, ist erfindungsgemäß vorgesehen, dass zumindest einer der Leitungsdrähte einen rechteckförmigen oder quadratischen Querschnitt aufweist .
Abstract:
The apparatus includes a flexible printed wiring device (18) having a region sized to receive the electronic component (10) and a channel (28) disposed within the flexible printed wiring device. The channel has an inlet end (32) and an outlet end (34) and has an orifice (36) disposed therein. The inlet end receives a fluid, the fluid is distributed to the orifice via the channel and the orifice directs the fluid towards the region, so that the fluid is in direct contact with the electronic component when the electronic component is disposed in the region.
Abstract:
PROBLEM TO BE SOLVED: To provide a heat radiation structure which has high bond strength in a cold cycle and achieves high cooling efficiency, a power module, a manufacturing method of the heat radiation structure, and a manufacturing method of the power module.SOLUTION: A power module 1 includes: an insulative ceramic substrate 10; a metal member 50 which is joined to a surface of the ceramic substrate 10 with a brazing material and is formed by a metal or alloy; and a heat radiation part 40 formed on a surface of the metal member 50 by accelerating powder, formed by a metal or alloy, with a gas and blowing the powder and the gas onto the surface while keeping the solid state of the powder to deposit the powder thereon. A heat pipe 60 is buried in the heat radiation part 40.
