Compact cold plate configuration utilizing ramped closure bars

Abstract

A method of communicating fluid through a cold plate includes communicating fluid through an internal header.

1 . A cold plate assembly comprising:
 an internal header with a fluid port, said fluid port in fluid communication with a fluid path B fin structure in a second layer which contains said fluid path B fin structure through a fluid outlet in a fluid path closure bar in a first layer which contains a fluid path A fin structure.   
     
     
         2 . The cold plate assembly as recited in  claim 1 , wherein said fluid outlet includes a ramped surface. 
     
     
         3 . The cold plate assembly as recited in  claim 1 , wherein said fluid outlet includes a stepped surface. 
     
     
         4 . A cold plate assembly comprising:
 a port;   an upper end sheet mounted to said port;   an upper parting sheet attached to said upper end sheet, said upper parting sheet includes an opening in communication with said port;   a fluid path B closure bar attached to said upper parting sheet, said fluid path B closure bar contains a fluid path B fin structure and a fluid path B channel;   a fluid path A closure bar, said fluid path A closure bar contains a fluid path A fin structure, said fluid path A closure bar defines a fluid path A closure bar outlet in communication with said fluid path B channel;   a middle parting sheet attached between said fluid path B closure bar and said fluid path A closure bar, said middle parting sheet includes a first opening in communication with said fluid path A closure bar outlet and a second opening in communication with said port.   
     
     
         5 . The cold plate assembly as recited in  claim 4 , wherein said fluid path A closure bar outlet includes a ramped surface. 
     
     
         6 . The cold plate assembly as recited in  claim 4 , wherein said fluid path A closure bar outlet includes a stepped surface. 
     
     
         7 . The cold plate assembly as recited in  claim 4 , wherein a lower parting sheet is attached to said fluid path A closure bar opposite said middle parting sheet. 
     
     
         8 . The cold plate assembly as recited in  claim 7 , further comprising a lower end sheet attached to said lower parting sheet. 
     
     
         9 . A method of communicating fluid through a cold plate comprising:
 communicating fluid through an internal header of the cold plate, the internal header communicates fluid through a fluid inlet which passes through a common layer of the cold plate with a fluid outlet.   
     
     
         10 . A method as recited in  claim 9 , further comprising ramping the fluid to a first layer which first receives the fluid from an inlet port from a second layer which receives fluid from the first layer. 
     
     
         11 . A method as recited in  claim 9 , further comprising stepping the fluid to a first layer which first receives the fluid from an inlet port from a second layer which receives fluid from the first layer.
