Thermoelectric heat exchanger

A thermoelectric heat exchanger comprising:

• a first heat sink having a first finned surface and an opposed planar first contacting surface, said first finned surface defining an array of first fins extending in an axial direction;
• a plurality of second heat sinks, each having a second finned surface and an opposed second planar contacting surface, said second finned surface defining an array of second fins extending in the axial direction;
• a plurality of sets of thermoelectric cooling elements, each of said sets made up of three cooling elements arranged in a triangular pattern and disposed between the second contacting surface of a respective one of the second heat sinks and the first contacting surface of the first heat sink;
• means for electrically connecting all three of the cooling elements within each set together in series;
• a gasket disposed between the first and second heat sinks and surrounding each set of cooling elements;
• a plurality of fasteners extending between the first and second heat sinks between adjacent ones of the cooling elements to ensure at least point contact between each of the cooling elements and both of the respective heat sinks;
• at least one fan centrally mounted over the first find to force cooling air from a central region of the first heat sink along the axial direction towards each end of the first heat sink;
• and
• means for applying an electrical voltage in parallel across each of the sets of cooling elements.
