Cooling tube included in aircraft heat exchanger

Abstract

A channel tube includes a body having first and second surfaces extending between first and second opposing ends to define a tube width. The first and second surfaces are separated from each other by a distance defining a tube height. A plurality of ports extend through the body and between the first and second surfaces to define a fluid path extending in a direction of the tube width. Each port defines a plurality of walls and a plurality of ribs having a thermal conductive surface to transfer heat therethrough. A first wall extends in a direction of the tube width. The second wall extends in a direction of the tube width and is disposed opposite the first wall. At least one rib is integrally formed between the first and second walls and extends perpendicular thereto.

1 . A channel tube included in a heat exchanger, comprising:
 a body including first and second surfaces extending between first and second opposing ends to define a tube width, outer surfaces of the first and second surfaces separated from each other by a distance defining a tube height; and   a plurality of ports extending through the body and between the first and second surfaces to define a fluid path extending in a direction of the tube width, each port defining a plurality of walls and a plurality ribs having a thermal conductive surface to transfer heat therethrough, the plurality of ribs comprising:   a first wall extending in a direction of the tube width;   a second wall extending in a direction of the tube width, the second rib wall disposed opposite the first wall; and   at least one rib integrally formed between the first and second walls and extending perpendicular thereto.   
     
     
         2 . The channel tube of  claim 1 , wherein the first wall, the second wall and the at least one rib are formed integrally to one another and define a port thickness that determines a heat transfer rate of liquid flowing through the port. 
     
     
         3 . The channel tube of  claim 2 , wherein the first and second ends include a curved portion extending radially from the body of the tube. 
     
     
         4 . The channel tube of  claim 3 , wherein the body consists of fourteen ports. 
     
     
         5 . The channel tube of  claim 4 , where the ports are rectangular-shaped to define a port height-to-port width ratio. 
     
     
         6 . The channel tube of  claim 5 , wherein the at least one rib has a width of 0.010 inches. 
     
     
         7 . The channel tube of  claim 6 , wherein the first and second walls have width of 0.014 inches. 
     
     
         8 . The channel tube of  claim 7 , wherein the port has height of 0.100 inches and a width of 0.0594 inches. 
     
     
         9 . The channel tube of  claim 8 , wherein the tube height is 0.128 inches. 
     
     
         10 . The channel tube of  claim 9 , wherein the body, the first and second walls and the at least one rib are integrally formed from a thermal conductive material. 
     
     
         11 . The channel tube of  claim 10 , wherein the thermal conductive material is aluminum. 
     
     
         12 . The channel tube of  claim 3 , wherein the width of the curved portion is 0.020 inches.
