Abstract
A cooling apparatus utilizing the Joule-Thomson effect contains a lead conduit including an inlet end connectable to a source of pressurized gas, and an outlet end, a relief nozzle provided at the outlet end of the lead conduit whereby pressurized gas inflowing through the lead conduit is depressurized at the relief nozzle with cooling, a return for the cooled and depressurized gas, and a countercurrent heat exchanger by which the pressurized gas inflowing through the lead conduit is in heat conductive contact with the cooled and depressurized gas outflowing through the return. Peltier elements serve for additional cooling of the inlet end of the lead conduit and have cold sides which are in immediate contact with the inlet end of the lead conduit. A heat exchanger is provided at the warm sides of the Peltier elements and is throughflown by the gas from the return.
