PROBLEM TO BE SOLVED: To provide a heat exchanger capable of adjusting a heat exchanging amount. SOLUTION: A heat exchanger 1 comprises a tube-storing chamber 4 communicated with a heat-exchanging chamber 2 where heat-exchanging fluid flows, a coil-like extendable or retractable tube 3 extended from the tube-storing chamber 4 to the heat-exchanging chamber 2, and an extending or retracting adjuster means 10 for adjusting an extending or retracting amount of the tube 3. Then, the aforesaid amount of extension and retraction is adjusted to cause a heat exchanging area of the tube 3 positioned inside the heat exchanging chamber 2 to be varied, and a heat exchanging amount is adjusted. |
