THERMOELECTRIC COOLING UNIT Russian patent published in 2014 - IPC F25B21/02 

FIELD: heating.

SUBSTANCE: thermoelectric cooling unit is applied in refrigerating engineering. A thermoelectric cooling unit includes two or more thermoelectric modules (2) arranged in sealed chamber (4) pre-vacuumised and filled with dry gas. Hot junctions of thermomodules are connected to liquid radiator (6) of the sealed chamber, and cold junctions are connected to condensers (7). Into each condenser there built are three independent thermosyphons (8) with internal steam lines (10); besides, evaporation zone (9) of thermosyphons is in the housing of air radiator (3) separated with heat-insulating insert (5) from the liquid radiator of the sealed chamber, which provides unidirectional heat transfer in case of power interruption of thermoelectric modules. Heat-insulated housing (1) forms internal and external thermal circuits. Fan (11) and electric heater (12) are installed on the air radiator housing.

EFFECT: use of the invention provides electric energy cost reduction.
