Abstract
PURPOSE: Into a cylinder having a lot of fins, specifically shaped core metal and sliding press device on the core metal are inserted and used to expand the cylinder, thereby to provide a high heat-transmission heat exchanger in simple and inexpensive way.
CONSTITUTION: A plurality of fins 2 having engaging portions is inserted into the outer surface of a cooling pipe 1. A core metal 4 has a diameter smaller than the I.D. of the cooling pipe 1 and receiving portion 3 at its end. Metal collars 8 and expandable 0-ring 6 are arranged in the space between the receiving portion 3, the core metal 4, and a slidable pressing body 5. The so assembled expanding device 7 is inserted into the cooling pipe 1, and the core metal 4 is fixed, the press body 5 is pushed to displace the 0-ring in radial direction so that the cooling pipe 1 is firmly contacted with the fins. The process causes the external surface of the cooling pipe to be plastically deformed to engage with the fins 2 internal surfaces. As a result, fluid flow changes to cause more effective heat transmission. The process, thus, provides simple, inexpensive means to produce heat exchangers.
