초록 ▼

A system and method for expanding, joining or securing a plurality of tubes by electromagnetic expansion to a plurality of sheets in a tubular heat transfer system. The system and method involve the automatic sensing and positioning of a electromagnetic coil in operative relationship with at least a portion of a tube and an inner wall of a sheet and then energizing the electromagnetic coil to expand the portion of the tube to engage the inner wall of the sheet, thereby securing the tube thereto. A tubular heat transfer system tube expander and method are also shown.

1. A method for securing a conductive tube to a surrounding member of a tubular heat transfer system, said method comprising the steps of:inserting a coil into a conductive tube; moving said coil along the inside of said tube; when said coil reaches a position at which said tube intersects said surrounding member, while the coil is moving, energizing said coil to expand the portion of the conductive tube at the position of intersection and thereby securing said conductive tube to said surrounding member. 2. The method of claim 1 wherein the method includes the additional steps of sensing the position at which said tube intersects said surrounding member and energizing said coil in response to sensing said intersection.3. The method of claim 1 wherein the method includes the additional steps of determining the position at which said tube intersects said surrounding member and energizing said coil in response to determining said intersection.4. The method of claim 1 wherein the method includes the additional steps of:moving the coil to a second position at which said tube intersects a second surrounding member, and when said coil reaches said second position, while said coil is moving, energizing said coil to expand the portion of the conductive tube at the position of intersection and thereby securing said conductive tube to said second surrounding member. 5. The method of claim 4 wherein the method includes the additional steps of sensing the position at which said tube intersects said surrounding members and energizing said coil in response to sensing said intersection.6. The method of claim 4 wherein the method includes the additional steps of determining the position at which said tube intersects said surrounding members and energizing said coil in response to determining said intersection.
