Abstract
Official abstract text for this publication.
A heat exchanger includes a body defining a flow channel, and a pin extending across the flow channel, the pin including an at least partially non-cylindrical shape. The pin can be a double helix pin including two spiral branches defining a double helix shape. The two branches can include a uniform winding radius. The two branches include a non-uniform winding radius. The non-uniform winding radius can include a base radius and a midpoint radius, wherein the midpoint radius is smaller than the base radius. The two branches can be joined together by one or more cross-members.
First claim
Opening claim text (preview).
What is claimed is: 1. A heat exchanger, comprising: a body defining a flow channel; and a pin extending across the flow channel, the pin including an at least partially non-cylindrical shape, wherein the pin is a double helix pin including two spiral branches defining a double helix shape, each branch having two ends, wherein the two branches are joined together by one or more cross-members, wherein the two branches extend across the flow channel such that the branches are connected to the body at two sides of the flow channel at respective ends of each branch. 2. The heat exchanger of claim 1 , wherein the two branches includes a uniform winding radius. 3. The heat exchanger of claim 1 , further comprising a plurality of pins. 4. The heat exchanger of claim 3 , wherein the plurality of pins includes pins of only one shape. 5. The heat exchanger of claim 3 , wherein the plurality of pins are defined in the channel in a predetermined pattern relative to each other.
