Patent ID: 8704076

Claim:
A thermoelectric tempering device having a plurality of thermoelectrically operating tempering elements ( 10 ), with a first side comprising a cold surface and an opposite side comprising a hot surface; air/heat exchange elements ( 11 , 11 ′) affixed to both sides and each accommodated in a flow conduit wherein each respective flow conduit ( 15 , 15 ′) is constructed so that each flow conduit encompasses the respective heat exchange elements ( 11 , 11 ′) in a flow direction; ventilators ( 13 , 13 ′) producing an air flow along the air/heat exchange elements, a housing ( 5 ) with a housing bottom part ( 6 ) and a housing top part ( 7 ), wherein the housing has at least one air inlet opening ( 14 , 14 ″) and at least one air outlet opening ( 16 , 16 ″), and wherein the ventilator ( 13 , 13 ″) of each respective flow conduit ( 15 , 15 ″) is situated at a respective inlet opening ( 14 , 14 ″) or outlet opening ( 16 , 16 ″) and wherein the air outlet opening and the air inlet opening are connected via the respective flow conduit, wherein the housing bottom part ( 6 ) has a detachably mounted housing bottom ( 28 ) on an underside and is covered on an opposite surface by the housing top part ( 7 ), and the flow conduits are formed of curved channels having partially constricted and partially expanded flow cross-sections, wherein the flow conduits are oriented parallel to the sides of the housing bottom part and positioned in the region of or near the tempering elements and in the same plane as the tempering elements so that a layered structure of flow conduits is produced, and wherein the partially constricted cross-sections exist before and after the tempering elements and the partially expanded regions are positioned in the space between either the housing bottom or the housing top part and the tempering elements.
