Patent ID: 8178966

Claim:
A method for cooling a circuit arrangement, comprising: providing: a substrate, one surface of which forms a main area, at least one integrated electronic component arranged at the main area, the at least one component arranged in the substrate or isolated from the substrate by an electrically insulating region; a housing surrounding and encapsulating the substrate, a liquid cooling mechanism situated entirely within the housing, wherein the substrate is located entirely within the housing; main channels formed in the substrate and arranged along the main area, each of the main channels completely surrounded by the substrate transversely with respect to a longitudinal axis; and 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; transporting a cooling liquid from a collecting trough located in the housing by capillary forces in the transverse channels as far as one or more of the main channels to which the transverse channels are connected such that coolant vapor exits from the main channels or transporting the cooling liquid from the collecting trough by capillary forces in the main channels as far as one or more of the transverse channels to which the main channels are connected such that coolant vapor exits from the transverse channels; and condensing the coolant vapor to form the cooling liquid, which is introduced into the collecting trough.
