Patent ID: 7119284

Claim:
A printed circuit board having an insulated metal substrate with an integrated cooling system, comprising: a metal substrate( 10 ); at least one electrically insulating layer ( 11 ) adhered to said metal substrate ( 10 ); and several electro-conducting tracks ( 12 ) capable of interconnecting electronic power components ( 24 ) adhered to said electrically insulating layer ( 11 ); wherein said metal substrate ( 10 ) incorporates at least one heat transporting cavity ( 13 ), having at least one opening ( 14 ) at one edge ( 19 ) of said metal substrate ( 10 ), said at least one heat transporting cavity ( 13 ) having located therein a conduit for a heat-carrying fluid, said conduits extending by way of said at least one opening ( 14 ) to the outside of, and upward from, said metal substrate ( 10 ) forming a sealed heat transfer area in an external heat transfer medium.
