Photochemical etching of microfluidic plates
Plate heat exchangers are found in numerous industrial applications, and essentially use metal plates to transfer heat between two fluids. Their use is burgeoning as they out-perform conventional heat exchangers (often a coiled pipe containing one fluid that passes through a chamber containing another fluid) as the fluids being cooled are in contact with a much greater surface area, which optimizes the transfer of heat and greatly increases the speed of temperature change.
