 |
module 4cm x 4cm, (1.6" x 1.6") with 127 p-n couples. When current passes through two different conductors, heat is produced in one and absorbed in the other. Peltier first described this in 1834. Modern semiconductor materials can make p-n junctions which produce large temperature differences. This 4cm x 4cm x 4mm thick module contains 127 p-n junctions connected electrically in series but thermally in parallel. Maximum temperature difference = 59 deg C at 30 deg C ambient with no heat load. Maximum ratings = 13.5V, 4.4A, 36W.
