Abstract
In a method of manufacturing a power module unit, cooling fins are positioned in recesses of a frame, in particular a metal frame. A first metallic material is applied to the cooling fins and the frame by a thermal spraying process, causing the applied first metallic material to produce a material bond between the cooling fins and the frame.

A method of manufacturing a power module unit, said method comprising:
- positioning cooling fins in recesses of a frame, in particular a metal frame;
- and
- applying a first metallic material to the cooling fins and the frame by a thermal spraying process, causing the applied first metallic material to produce a material bond between the cooling fins and the frame.
A heat sink for a power module unit, said heat sink comprising:
- a frame, in particular a metal frame;
- cooling fins positioned in recesses of the frame;
- and
- a first metallic material applied to the cooling fins and the frame by a thermal spraying process to produce a material bond between the cooling fins and the frame.
A power module unit, comprising a heat sink, said heat sink comprising a frame, in particular a metal frame, cooling fins positioned in recesses of the frame, and a first metallic material applied to the cooling fins and the frame by a thermal spraying process to produce a material bond between the cooling fins and the frame.
