<p>PROBLEM TO BE SOLVED: To provide a heat exchanger at low cost and in a compact manner, which exhibits high performance concerning heat resistance, pressure resistance, liquid leakage, heat exchange rate and so forth.SOLUTION: A heat exchanger 1 comprises a stacked plate assembly 11 having stacked plates 111, and a casing 12 of a hollow pipe shape, which houses the stacked plate assembly 11 inside and extends in the direction of stack. Two kinds of fluids to be heat-exchanged flow in a circular arc manner in the insides of hollow parts formed between adjacent two plates 111 without mixing with each other. Adjacent hollow parts are connected in series by bypasses. The first bypasses 2112, 2118 of a flow passage in the stack direction for entrance and exit of the first fluid are provided on both sides of the second bypass 1113 of a flow passage in the stack direction for the second fluid, and the flow passage for the first fluid does not detour around the flow passage for the second fluid in the stack direction, so that the flow passage for the first fluid and the flow passage for the second fluid can be formed large without interfering with each other.</p> |
