The specific thermal resistance values of several thermal interface materials (TIMs) intended to thermally enhance Cu contact pairs and their degradation under isothermal ageing at 170°C have been investigated using Cu stack samples consisting of 10 Cu discs and 9 layers of the TIMs. The results obtained indicate that the specific thermal resistance values of the as-prepared Cu stack samples, one...
The use of an innovative jet impingement cooling system in a power electronics application is investigated using numerical analysis. The jet impingement system, outlined by Skuriat et al, consists of a series of cells each containing an array of holes. Cooling fluid is forced through the device, forming an array of impingement jets. The jets are arranged in a manner, which induces a high degree of...
Liquid jet impingement can be used to efficiently generate high heat transfer coefficients for cooling. However, optimization of the jet impingement array is complicated as a large number of geometrical parameters, such as array size, jet spacing and jet diameter affect performance. In the studies described in this paper a custom designed half-bridge substrate tile, supporting two IGBT and two diode...
