ABSTRACT:
A cooling device for rapidly cooling items, such as biological samples. The cooling device includes an enclosure having a chamber and an air circulation path at least partially within the chamber. A fan is operatively connected to the chamber for circulating air within the air circulation path and a perforated tube is disposed within the air circulation path for receiving a liquid refrigerant under pressure and distributing refrigerant in gaseous form to the air circulation path. Preferably the perforated tube is formed as a coil having multiple revolutions and either an axial blade fan or a centrifugal fan is received generally within the coils.
