Abstract

A heat exchanger has a base that is part of a heat producing component or is attached to a heat producing component and fins mounted on the base as is conventional. Spheres (also called beads or particles or balls) are located in the spaces between the fins, and the fins are arranged to hold the spheres in a suitable packing arrangement. The spheres can be made of a poor conductor of heat and produce turbulence in a fluid flowing through the heat exchanger without otherwise transferring heat between the base and the fluid. Alternatively, the spheres can be made of a good heat conductor to increase the heat transfer provided by the fins. Thermally conductive spheres can be packed loosely or can be fused for better heat transfer.

Heat Exchanger with Packed Spheres to Produce Turbulence and Fins Supporting the Spheres

A heat exchanger has a base that is part of a heat producing component or is attached to a heat producing component and fins mounted on the base as is conventional. Spheres (also called beads or particles or balls) are located in the spaces between the fins, and the fins are arranged to hold the spheres in a suitable packing arrangement. The spheres can be made of a poor conductor of heat and produce turbulence in a fluid flowing through the heat exchanger without otherwise transferring heat between the base and the fluid. Alternatively, the spheres can be made of a good heat conductor to increase the heat transfer provided by the fins. Thermally conductive spheres can be packed loosely or can be fused for better heat transfer.

In one example, pin fins are mounted on the base in rows and columns (or rows and offset columns) and spheres are with space between pins to hold a sphere. The pins are high enough to hold one or a few layers of spheres.

The drawing shows an example with thin rectangular fins that are formed from a single sheet of metal. The drawing shows a base 2, fins 3, and spheres 4.
