THERMOELECTRIC DEVICE TO MAINTAIN TEMPERATURE MODE Russian patent published in 2012 - IPC H05K7/20 

FIELD: electricity.

SUBSTANCE: invention relates to a thermoelectric device to maintain a temperature mode, comprising several elements (10) operating on thermoelectricity and maintaining the temperature mode with a cold surface produced on their one side as current is supplied and warm surface on their opposite side, with air heat exchange bodies (11, 11') installed on both sides and placed in an appropriate chamber for air flow passage and fans (13, 13') causing air flow along them. Easy opportunities for adjustment and expansion are available due to the fact that a device unit formed as a module (1) for maintenance of the temperature mode to maintain the temperature mode is arranged so that chambers for air flow are arranged in the form of through channels (15, 15') that surround heat exchange bodies (11, 11') at sides in parallel to the flow direction and on the side opposite to the elements (10) maintaining the temperature mode, arranged as bent and having narrowed and expanded cross sections, which have an air input hole (14, 14') and an air output hole (16, 16'), besides, a fan (13, 13') of the appropriate through channel (15, 15') is arranged near its input hole (14, 14') or near its output hole (16, 16').

EFFECT: invention provides for optimisation of a flow, which serves for improvement of heat transfer.
