Title:
STAGED GRAPHITE FOAM HEAT EXCHANGERS
Document Type and Number:
WIPO Patent Application WO/2012/106605
Kind Code:
A3
Abstract:
Shell-and-tube heat exchangers that utilize one or more foam heat transfer units engaged with the tubes to enhance the heat transfer between first and second fluids. The foam of the heat transfer units can be any thermally conductive foam material that enhances heat transfer. In an embodiment, a liquid distribution unit is employed that sprays a fluid to maximize the energy transfer through the use of large surface/volume ratio of the sprayed fluid. The spraying can be used in combination with or separately from the foam heat transfer units. Also, the tubes can be helically twisted around the liquid distribution unit so that the sprayed fluid impinges on the tubes. The shell-and-tube heat exchangers described herein are highly efficient, inexpensive to build, and corrosion resistant. The heat exchangers can be configured as an evaporator, a condenser, or for single phase cooling or heating thermal transfer applications.
