Electronic power circuit with flat heat sink device

摘要

The electronic circuit has a flat heat sink device (4) for dissipating the waste heat generated by the power components of the electronic circuit , e.g. insulated gate bipolar transistors. The heat sink device has deformable regions for providing heat reception areas (8), heat transport areas (10) and heat dissipation areas (11). The heat sink device may incorporate cooling fluid channels and/or hollow spaces (9) containing a gas which is vaporised by the received heat and condensed upon heat dissipation.
