Baffles for thermal transfer devices

Abstract

A baffle for a fluid collection portion of a thermal transfer device can include a body having an inner perimeter, an outer perimeter, and an asymmetric feature, where the asymmetric feature is configured to create a pressure drop within the fluid collection portion of the thermal transfer device. The inner perimeter can be configured to be at least as large as an inner surface of a first wall that forms the fluid collection portion of the thermal transfer device. The outer perimeter can be configured to be no larger than an outer surface of a second wall that forms the fluid collection portion of the thermal transfer device.

1 . A baffle for a fluid collection portion of a thermal transfer device, wherein the baffle comprises:
 a body comprising an inner perimeter, an outer perimeter, and an asymmetric feature, wherein the asymmetric feature is configured to create a pressure drop within the fluid collection portion of the thermal transfer device,   wherein the inner perimeter is configured to be at least as large as an outer surface of a first wall that forms the fluid collection portion of the thermal transfer device,   wherein the outer perimeter is configured to be no larger than an inner surface of a second wall that forms the fluid collection portion of the thermal transfer device, and   wherein the asymmetric feature comprises a difference in a distance between the inner perimeter and the outer perimeter.   
     
     
         2 . The baffle of  claim 1 , wherein the asymmetric feature starts at a first side of the body and ends at a second side of the body, wherein the first side and the second side are opposite each other. 
     
     
         3 . The baffle of  claim 2 , wherein the first side of the body is configured to be located proximate to an outlet of the thermal transfer device. 
     
     
         4 . The baffle of  claim 2 , wherein the second side of the body is configured to be located proximate to an outlet of the thermal transfer device. 
     
     
         5 - 9 . (canceled) 
     
     
         10 . The baffle of  claim 1 , wherein the body is planar. 
     
     
         11 . The baffle of  claim 1 , wherein the body asymmetric feature comprises a curvature to the body. 
     
     
         12 . A fluid collection portion of a thermal transfer device, wherein the fluid collection portion comprises:
 a first wall having an outer surface;   a second wall having an inner surface;   an outlet; and   a first baffle disposed between the first wall and the second wall, wherein the first baffle comprises a first baffle body having a first inner perimeter, a first outer perimeter, and a first asymmetric feature, wherein the first asymmetric feature is configured to create a pressure drop within the fluid collection portion of the thermal transfer device, wherein the pressure drop forces fluid proximate to the first baffle to traverse toward the outlet,   wherein the first inner perimeter is configured to be at least as large as the outer surface of the first wall that forms the fluid collection portion of the thermal transfer device, and   wherein the first outer perimeter is configured to be no larger than the inner surface of the second wall that forms the fluid collection portion of the thermal transfer device.   
     
     
         13 . The fluid collection portion of  claim 12 , wherein the first baffle is directly coupled to the outer surface of the first wall. 
     
     
         14 . The fluid collection portion of  claim 12 , wherein the first baffle abuts against the outer surface of the first wall. 
     
     
         15 . The fluid collection portion of  claim 12 , wherein the first baffle is directly coupled to the inner surface of the second wall. 
     
     
         16 . The fluid collection portion of  claim 12 , wherein the first baffle abuts against the inner surface of the second wall. 
     
     
         17 . The fluid collection portion of  claim 12 , wherein the first asymmetric feature comprises at least one gap through which fluid flows. 
     
     
         18 . The fluid collection portion of  claim 12 , further comprising:
 a second baffle disposed between the first wall and the second wall, wherein the second baffle comprises a second baffle body having a second inner perimeter and a second outer perimeter.   
     
     
         19 . The fluid collection portion of  claim 18 , wherein the second baffle further comprises the first asymmetric feature. 
     
     
         20 . The fluid collection portion of  claim 18 , wherein the second baffle further comprises a second asymmetric feature. 
     
     
         21 . The baffle of  claim 1 , wherein the distance is greatest opposite an outlet of the thermal transfer device. 
     
     
         22 . The baffle of  claim 21 , wherein the distance gradually increases towards the outlet of the thermal transfer device. 
     
     
         23 . The baffle of  claim 21 , wherein the baffle has no apertures therethrough. 
     
     
         24 . The baffle of  claim 21 , wherein the distance between the inner perimeter and the outer perimeter is not uniform along the baffle. 
     
     
         25 . The baffle of  claim 21 , wherein the distance is zero closest to the outlet of the thermal transfer device.
