Vortex refrigerator with industrial cabinet

The utility model provides an improved vortex refrigerator with an industrial cabinet. The utility model is characterized in that a vortex chamber in the form of a cylinder is replaced by a vortex chamber in the form of an Archimedes spiral for improving the vortex quality; a pin valve adjustor is replaced by a cone vortex preventing device to improve the separating effect of cold air currents and hot air currents for increasing the refrigerating efficiency. The hot pipe segment of the vortex refrigerator with the industrial cabinet is of the structure of inside and outside casing pipes, and the hot air currents which are separated by the cone vortex preventing device are discharged after flowing through the back space of the inside pipe of the hot pipe segment and the outside pipe of the hot pipe segment for lowering the discharged temperature of the hot air currents and improving the working environment. The cold pipe segment of the vortex refrigerator with the industrial cabinet is of the structure of inside and outside casing pipes; the length of the inside pipe of the cold pipe segment is extended; the outside pipe of the cold pipe segment is additionally opened with an outlet for guiding the hot air currents of the industrial cabinet, and an extensive cold air current loop for achieving ideal uniform cooling effect is formed in the industrial cabinet. The utility model which has the advantages of low noise, little pollution, no moving pieces, compact structure, convenient installation and free maintenance is especially suitable for the arrangement of precision instruments and the refrigerating requirements of the industrial cabinet which requires small range of the cold amount.
