Abstract
Abstract A modular reflux cooling plate (10) having a condenser region (11) above the boiling channels (12) or above and below (11,24) the region (11), boiling channels (12) and downcomers (16) which effect reflux cooling of electrical power modules used in aircraft and the like. Air flow fins (18) are arranged adjacent the condenser (11) or condensers (11,24) and the boiling channels (12) to effect cooling of a coolant vapor which has entered the condenser (11) after being boiled from a liquid state in the boiling channels (12) as a result of the heat generated by one or more power modules affixed to an end plate (14) by any suitable means and to provide a parallel heat transfer path which shares the heat transfer task with the reflux cooling during normal system operation and which provides emergency heat transfer when reflux cooling is not available.

Claim 1
Independent Claim
213 words
A modular reflux cooling plate, for one or more heat generating components, comprising: at least one condensing region; boiling channels disposed adjacent the at least one condensing region; at least one downcomer in the vicinity of the boiling channels so as to be operatively communicated between the at least one condensing region and the boiling channels; end plates hermetically sealing the at least one condensing region, the boiling channels and the at least one downcomer therebetween so that a coolant can be provided in the region of the boiling channels, and means for supplying cooling air from the boiling channels to the at least one condensing region arranged adjacent one of the end plates to define a cooling circuit defined by the boiling channels, the at least one condensing region, and the at least one downcomer, wherein the one or more heat generating components are mounted externally on the other of the end plates adjacent the boiling channels to form an assembly adapted to be joined with one or more other modular reflux cooling plates with assemblies thereon for providing shared heat exchange between the at least one condensing region and the cooling air supply means, wherein the at least one condensing region comprises a condensing region above and below the boiling channels.
