Patent ID: 7872349

Claim:
An integrated coolant circuit arrangement comprising: a unitary substrate, the unitary substrate having one surface of which forms a main area, the unitary substrate being made of a monocrystalline material; a housing surrounding and encapsulating the unitary substrate, a liquid cooling medium situated entirely within the housing, wherein the unitary substrate is located entirely within the housing; at least one integrated electronic component arranged at the main area, the at least one component arranged in the unitary substrate or isolated from the unitary substrate by an electrically insulating region; main channels formed in the unitary substrate and arranged along the main area, each of the main channels completely defined within a single layer of the unitary substrate transversely with respect to a longitudinal axis; transverse channels arranged transversely with respect to the main channels, each transverse channel opening into at least one main channel, and more than about ten transverse channels opening into one main channel; and wherein the housing contains a first condensing device or a second condensing device connected to the housing, the first or second condensing device condensing gaseous cooling medium to form the liquid cooling medium, wherein the first or second condensing device is located entirely within the housing.
