Abstract
A tubular heat exchanger designed for easy and compact mounting within a receiver tank. Within the rigid casing of the heat exchanger are mounted a plurality of spaced, parallel tubes. Coolant fluid entering one end of the heat exchanger, flows through a group of the tubes, and returns to the same end of the heat exchanger through the remaining tubes, whereupon it exits the exchanger. Hot fluid such as compressed air enters one end of the exchanger, passes along the length of the exchanger while intermingling with the tubes so as to be cooled, and then exits into a receiver tank through a plurality of holes located in the opposite end of the heat exchanger.
Claims10
An aftercooler for cooling compressed gas such as compressed air, the aftercooler including a tubular casing having a plurality of internal ducts for conveying coolant fluid therethrough with spaces between the ducts, said casing having a first inlet port for introducing coolant fluid into the casing to pass through certain of said cooling ducts, an outlet port for discharging spent cooling fluid from the casing, said casing having a second inlet port for introducing a compressed gas to be cooled such as compressed air into the casing to pass in the spaces between the cooling ducts, said casing having outlet means adjacent one end thereof for exiting the cooled compressed gas from the casing and into a receiving tank, and said casing having means for fixing a portion of said casing to a wall of a receiving tank with said outlet means for the compressed gas located within a receiving tank, and with said inlet and outlet ports for the cooling fluid located externally of a receiving tank, and wherein said inlet and outlet ports for the coolant fluid are situated adjacent the end of the casing opposite said one end where said outlet means for the compressed gas is located, and wherein the outlet means for exiting the compressed gas includes a first set of a plurality of small apertures angularly spaced around the periphery of the casing for reducing noise associated with the discharge of the compressed gas.
In combination with a receiving tank for a compressed gas such as a receiving tank in an air compressor system for receiving compressed air to be subsequently discharged at a point of use and wherein the receiving tank includes a chamber for receiving the compressed gas;
- an aftercooler for cooling the compressed gas prior to receipt in the receiving tank, the aftercooler including an elongated body having heat exchange means therein, said body being mounted to the receiving tank with a first portion of said body being received in said chamber and with a second portion of said body being located externally of the receiving tank, said body having an inlet port located in said second portion thereof for directing the compressed gas into said body to be cooled, and said body having in said second portion thereof an outlet means for discharging the compressed gas after cooling into said chamber, and wherein said outlet means includes a plurality of small angularly spaced apertures communicating with said chamber for exiting the cooled compressed gas directly into said chamber of the receiving tank.
