1. An impingement cooling apparatus including a heat liberating device, the impingement cooling apparatus including in combination:
- a housing having an end of said housing in intimate contact with said device,a stack of plates fitted within and parallel to said housing end, one of said plates being an impingement orifice plate adjacent said end of said housing where said device is located, said orifice plate having impingement orifice regions characterized by coolant flow impingement orifices passing therethrough, said orifice plate having coolant drainage return means adjacent said impingement orifice regions,the remaining plates positioned adjacent said orifice plate and between said orifice plate and a coolant inlet means and a drainage means, each of said plates having at least one opening therethrough, each said opening cooperating with the opening on an adjacent plate to form an inlet channel means between said coolant inlet means and said orifice plate to thereby allow the establishment of a coolant flow path to said orifice plate to thereby supply coolant through said orifice to impinge at right angles upon said end of said housing to provide impingement cooling of said heat liberating device,said coolant being returned via said coolant drainage return means adjacent said impingement orifice regions and a return channel means from said orifice plate to said drainage means whereby a drainage flow path is established such that coolant after impinging upon said end of said housing passes back past said stack of plates to said drainage means and is free from cross-flow with said coolant flow path delivered through said inlet channel means to said impingement plate to thereby provide maximum heat transfer from said device to said coolant.

Abstract
The present invention relates to an impingement cooling apparatus for use in the removal of heat from a heat liberating device. The apparatus includes a housing on which the device is secured and a stack of plates fitted within the housing. One of the plates is an impingement orifice plate adjacent the housing where the device is located. The orifice plate has a region that is characterized by coolant flow impingement orifices passing therethrough. The orifice plate also has a coolant drainage return adjacent the impingement orifice region.

15. An impingement cooling apparatus including a heat liberating device, the impingement cooling apparatus including in combination:
-
a heat transmitting means positioned between said heat liberating device and a first impingement orifice means, said first impingement orifice means positioned in a plane parallel to said heat transmitting means and having an orifice passing therethrough, said first impingement orifice means being thermally, mutually coupled to said heat transmitting means and a second impingement orifice means, said first impingement orifice means having portions thereof spaced apart from said heat transmitting means and said second impingement orifice means to thereby cause heat liberated from said device to be conducted through said heat transmitting means to said first and second impingement orifice means, said second impingement orifice means having an orifice therethrough that is in non-aligned relationship with said orifice of said first impingement means, means to deliver coolant in a path to and through said orifice of said second impingement means at a right angle to said first impingement means and thereafter to and through said orifice of said first impingement means whereupon said coolant impinges at a right angle to and upon said heat transmitting means, drainage means coupled to said heat transmitting means and said first and second impingement orifice means to thereby provide an isolated coolant return path of coolant that has come in impinging contact with said heat conducted from said device via said heat transmitting means and said first impingement orifice means, said coolant return path located such that said coolant passes back past said first and second impingement orifice means and is free from cross-flow with said coolant delivery path to thereby provide maximum heat transfer from said device to said coolant. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An impingement cooling apparatus including a heat liberating device, said apparatus including in combination:
-
a stacked series of heat transfer surface fins, thermally coupled by conduction means to said device at one end of said stacked series of fins, each of said fins having an orifice passing therethrough, said fin orifices each being in non-alignment with the orifice of an adjacent fin, means to provide coolant to and through said fin orifices in a direction towards said device to thereby cause said coolant passing through said orifices to impinge upon the next fin encountered in the direction of coolant flow and finally upon said conduction means, said coolant being returned via a coolant drainage return means adjacent said stacked series of heat transfer surface fins and a return channel means from said conduction means to said drainage means whereby a drainage flow path is established such that coolant after impinging upon said conduction means passes back past said stack of plates to said drainage means and is free from cross-flow with said coolant flow path delivered through said inlet channel means to said impingement plate to thereby provide maximum heat transfer from said device to said coolant. - View Dependent Claims (28)
