HEAT EXCHANGER WITH VIBRATOR TO REMOVE ACCUMULATED SOLIDS
First Claim
Patent Images
1. A heat exchanger comprising:
- at least one heat exchanger tube for receiving a cooling fluid;
a space around said at least one tube for receiving a gas to be cooled; and
an ultrasonic device for vibrating at least a portion of said heat exchanger to remove built up accumulation on said at least one tube, said ultrasonic device being operable to vibrate said at least one tube while a working gas is flowing over said at least one tube.

Abstract
A ultrasonic transducer is associated with a heat exchanger and is operable to vibrate a tube associated with the heat exchanger to break up accumulated solids which may have formed on an outer periphery of the tube. A gas flow passes over the tube to remove the pulverized solids.

5. A system for supplying an air flow into an enclosed space comprising:
-
a pair of heat exchangers, each of said heat exchangers having at least one heat exchanger tube for receiving a cooling tube; valving for selectively delivering an airflow over a first of said pair of heat exchangers, while a purge gas flows over a second pair of heat exchangers; and an ultrasonic device for vibrating at least one tube of the second heat exchanger as the purge gas flows over the at least one tube to remove solids which have been previously built up on said at least one tube of said second heat exchanger. - View Dependent Claims (6, 7, 8)

9. A method of operating a heat exchanger comprising the steps of:
-
passing a cooling fluid through a heat exchanger tube; passing a gas to be cooled around said tube; and vibrating at least a portion of said tube to remove built up accumulation while a working gas is flowing over said tube. - View Dependent Claims (10, 11, 12)
