COOLING DEVICE Russian patent published in 1998 - IPC

FIELD: cooling devices. SUBSTANCE: cooling device has water-and-oil separator, vortex flow divider and metering unit which form together closed cooling system. Water-and-oil separator is connected with heat exchanger through check valve. Vortex flow divider is mounted in parallel with heat exchanger and is brought in communication with this heat exchanger through hot and cold media supply loops forming combined heat exchanger-cooler. Metering unit is made in form of accumulating proportioning reservoir with dividing piston and system of control pneumatic valves. Metering unit is brought in communication with working reservoirs used for storage and delivery of finished product by means of check and blow valves. EFFECT: avoidance of drainage of carbon dioxide due to controllable pneumatic valve fitted in filling and blowing system which enhanced ecological and operational safety. 1 dwg
