摘要： A heat exchanger for cooling system compressed air dehumidifiers includes an inner body forming a dehumidifying passage provided with a cooler, an outer body surrounding the inner body and forming a precooling passage along the outer periphery of the inner body, an air supply port opened in the outer body through which compressed air is led into the precooling passage from one end thereof, a communicating hole opened in the inner body to guide the air led into the precooling passage out through its other end into the dehumidifying passage through one end thereof, and a plurality of heat transmitting pipes extending through the precooling passage in order to form an air-flow passage which guides the compressed air out of the other end of the dehumidifying passage to an air discharge port provided in the outer body. The heat of the compressed air in the air-flow passage which has been cooled and dehumidified in the dehumidifying passage and is flowing towards the air discharge port is exchanged with that of the compressed air of relatively high temperature in the precooling passage flowing from the air supply port towards the dehumidifying passage. In this manner, the heat exchanger simultaneously precools the compressed air to be dehumidified and heats already dehumidified compressed air. Further, by maintaining the outer body which forms the outer surface of the heat exchanger at a relatively high temperature dewdrops on the surface are prevented from forming.
