Abstract

A heat exchanging system includes one or more heat exchanging portions, wherein each heat exchanging portion includes an optimized internal fin structure. The optimization of the optimized internal fin structure includes receiving existing heat exchanging system information, analyzing exterior fluid flow around the one or more heat exchanging portions as a heat flux analysis, determining boundary conditions of a heat flux distribution based on the heat flux analysis, receiving material properties of the one or more heat exchanging portions, and designing the optimized internal fin structure based on the existing heat exchanging system information, the boundary conditions of the heat flux distribution, and the material properties of the one or more heat exchanging portions.

First claim

The invention claimed is:

1. A method, comprising:
receiving existing heat exchanging system information;
analyzing exterior fluid flow over an exterior surface of one or more heat exchanging structure as a heat flux analysis, the one or more heat exchanging structure including an aperture through which an interior fluid is passable and including an internal fin that projects into the interior fluid;
determining, via processing circuitry, boundary conditions of a heat flux distribution based on the heat flux analysis;
receiving material properties of the one or more heat exchanging structure; and
designing an optimized structure of the internal fin based on the existing heat exchanging system information, the boundary conditions of the heat flux distribution, and the material properties of the one or more heat exchanging structure.

2. The method of claim 1 , wherein the one or more heat exchanging structure is polygonal, circular, or elliptical.

3. The method of claim 1 , wherein the existing heat exchanging system information includes geometric information of flow domain, location of heat sources, magnitude of heat sources, solid material properties, fluid properties, and flow properties.

4. The method of claim 1 , wherein the heat flux distribution is non-uniform.

5. The method of claim 1 , wherein the optimized structure of the internal fin is non-straight.

6. The method of claim 1 , wherein the optimized internal fin structure is fabricated out of thermal conductivity enhanced plastic materials or metals.
