Al-AlN composite material, related manufacturing method and heat exchanger using such composite material

A method of manufacturing an Al—AlN composite material, the method comprising:

• melting aluminum in an area over one surface of an AlN plate under inactive gas atmosphere;
• flowing melted aluminum in the area over the one surface of the AlN plate under inactive gas atmosphere;
• placing a forming die on a layer of melted aluminum present on the one surface of the AlN plate;
• and
• solidifying the layer of melted aluminum to form an Al plate bonded to the AlN plate.

A heat exchanger for cooling a heating body, comprising:

• a cooling tube;
• and
• an Al—AlN composite material interposed between the heating body and the cooling tube to initiate a heat exchange between the heating body and the cooling tube;
• wherein the Al—AlN composite material comprises an Al plate, made of aluminum and having one surface formed with a heat dissipating surface associated with the cooling tube, and an AlN plate made of aluminum nitride and bonded to the other surface of the Al plate upon melting aluminum on the AlN plate under inactive gas atmosphere after which melted aluminum is solidified.
