Title:
METHOD OF MANUFACTURING TWISTED TUBE-TYPE HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2006284009
Kind Code:
A
Abstract:
To perform sound joining without needing large-scaled expensive equipment, coating of flux and cleaning to eliminate the flux.
A refrigerant tube 3 is wound on water piping 2 along a plurality of spiral grooves 2a formed on an outer periphery of the water piping 2, the water piping 2 on which the refrigerant tube 3 is wound is bent to a prescribed dimension, the bent water piping 2 and the refrigerant tube 3 are coated with thermosetting resin adhesive 4 having high heat conductivity, and the water piping 2 and the refrigerant tube 3 coated with the thermosetting resin adhesive 4 are heated in the atmosphere to be closely joined to each other.
