Low-temperature destroyer.

摘要

Low-temperature destroyer is provided with thermoelectric modules (5), whose cold junction is in thermal contact with core (2) of cryoprobe (1). Thermoelectric modules (5) are connected in multi-stage thermoelectric cascades (4), which are arranged around the core (2) of cryoprobe (1). The cold junction of the highest stage of every cascade (4) is structurally connected with the core (2) of the cryoprobe (1), whereas the hot junction of the first stage of every cascade (4) is connected structurally with a cooling system (6). Moreover, to the core (2) of the cryoprobe (1) there is mounted a sorption pump (7) for maintaining inside the casing (3) a static vacuum, and in said casing (3) there is installed a vacuum valve (8).
