Radiator Tube with Angled Flow Passage

Abstract

A radiator tube. Implementations of a radiator tube may include a tube body with external sides including an internal flow passage defined by the tube body oriented obliquely with respect to one or more external sides of the tube body.

1 . A radiator tube comprising:
 a tube body with external sides; and   an internal flow passage defined within the tube body and oriented obliquely with respect to one or more of the external sides of the tube body.   
   
   
       2 . The radiator tube of  claim 1 , wherein the tube body is coupled to a facesheet. 
   
   
       3 . The radiator tube of  claim 2 , wherein the tube body is substantially rectangular. 
   
   
       4 . The radiator tube of  claim 3 , wherein a short side of the tube body is coupled to the facesheet. 
   
   
       5 . The radiator tube of  claim 2 , wherein the internal flow passage is substantially rectangular. 
   
   
       6 . The radiator tube of  claim 1 , wherein the tube body is substantially rectangular. 
   
   
       7 . The radiator tube of  claim 1 , wherein the internal flow passage is substantially rectangular. 
   
   
       8 . The radiator tube of  claim 1 , wherein the internal flow passage has an aspect ratio of at least about 2.5:1. 
   
   
       9 . The radiator tube of  claim 1 , wherein the internal flow passage is oriented obliquely between one of:
 about 0.01 to 89.99 degrees; and   about 90.01 to 179.99 degrees.   
   
   
       10 . A radiator tube comprising:
 a rectangular tube body with external sides; and   a rectangular internal flow passage defined within the tube body and oriented obliquely with respect to one or more of the exterior sides of the tube body.   
   
   
       11 . The radiator tube of  claim 10 , wherein the rectangular internal flow passage has an aspect ratio of at least about 2.5:1. 
   
   
       12 . The radiator tube of  claim 10 , wherein the rectangular tube body is coupled to a facesheet. 
   
   
       13 . The radiator tube of  claim 10 , wherein a short side of the rectangular tube body is coupled to the facesheet. 
   
   
       14 . The radiator tube of  claim 10 , wherein the rectangular internal flow passage is oriented between one of:
 about 0.01 to 89.99 degrees; and   about 90.01 to 179.99 degrees.   
   
   
       15 . A spacecraft radiator system comprising:
 a plurality of tube bodies, each tube body comprising an internal flow passage defined within the tube body and oriented obliquely with respect to one or more exterior sides of the tube body; and   at least one facesheet in thermal communication with an external low-temperature radiative environment coupled to the plurality of tube bodies.   
   
   
       16 . The spacecraft radiator system of  claim 15 , wherein the plurality of tube bodies are substantially rectangular. 
   
   
       17 . The spacecraft radiator system of  claim 15 , wherein the internal flow passage in each of the plurality of tube bodies is substantially rectangular. 
   
   
       18 . The spacecraft radiator system of  claim 17 , wherein the rectangular internal flow passages of the plurality of tube bodies have an aspect ratio of at least about 2.5:1. 
   
   
       19 . The spacecraft radiator system of  claim 16 , wherein the plurality of tube bodies each comprise a short side and the short side of each of the plurality of tube bodies is coupled to the at least one facesheet. 
   
   
       20 . The spacecraft radiator system of  claim 15 , wherein the rectangular internal flow passage is oriented obliquely between one of:
 about 0.01 to 89.99 degrees; and   about 90.01 to 179.99 degrees.
