Abstract
A substantially planar heat exchanger for regulating the temperature of objects using a fluid coolant includes a bottom plate, a top plate, a fin insert sealed therebetween and a coolant inlet and outlet. The fin insert may include a plurality of substantially flattened omega-shaped or teardrop-shaped fins, which enhances the transfer of heat from the top and/or bottom plates into the fin insert. The omega-shaped fin inserts enhance the contact surface area between the plates and the insert to improve thermal migration therebetween. The fin insert may be constructed, for example, by forming convolutions in a sheet of metal, and compressing the convolutions laterally inwardly and vertically inwardly.
