Abstract
Disclosed are a hybrid heat sink and a hybrid heat sink assembly for a power module. The hybrid heat sink comprises a base provided with at least one power module on one side thereof, a first heat dissipation unit being a first heat dissipation fin group which is composed of a plurality of heat dissipation fins intervally arranged and is located on the other side of the base, and a second heat dissipation unit comprising a plurality of heat pipes and a second heat dissipation fin group. Each of the heat pipes comprises an evaporating section provided in the base and close to the power module, a condensing section, and an adiabatic section located between the evaporating section and the condensing section and comprises an extension portion and a folding portion, the second heat dissipation fin group is provided on the condensing sections.
