METHOD OF INSTALLING HEAT EXCHANGER

PROBLEM TO BE SOLVED: To easily install a heat exchanger body without changing a layout pattern of a heat exchanging tube.SOLUTION: On the ground, a heat exchanging tube 12 wound into a coil is shifted in a direction along a coil surface and extended to form a winding part 16 including an array of continuous loops 18. The heat exchanging tuber 12 connected to the winding part 16 is extended along an arrangement direction of the loop 18 to form a linear part 20. The loops 18 of the winding part 16 and the linear part 20 arranged under the loop 18 are connected by a retainer 26. The loops 18 constitute a positioned heat exchanger body 14. The heat exchanger body 14 is installed in a groove 32 with a loop surface of the loop 18 erected, to fill the groove 32.
