Patent number: 6400013Abstract: A thermoelectric module is capable of successfully reducing the heat stress for increased reliability. The module includes a plurality of thermoelectric chips of P-type and N-type arranged in a matrix between sets of first and second contacts to form a series electrical circuit. The chips are arranged to give at least three chip arrays each having a limited number of the chips. A first carrier is provided on one side of the chips to carry the first contacts and to include first bridges each integrally joining two adjacent first contacts to define first discrete couples for electrical connection of the chips in each chip array. The first carrier further includes at least two inter-array bridges which are solely responsible for electrical interconnection between the adjacent chip arrays.Type: GrantFiled: November 13, 2000Date of Patent: June 4, 2002Assignee: Matsushita Electric Works, Ltd.Inventors: Michimasa Tsuzaki, Nobuteru Maekawa, Narimasa Iwamoto, Junji Imai, Hiroaki Okada, Teruaki Komatsu, Shinya Murase, Hiroyuki Inoue, Masayuki Sagawa, Yuri Sakai
