PURPOSE:To enable to increase and decrease the number of heat exchanger blades to meet with the copacity of a heat exchanger, by superposing a plurality of heat exchanger blades by the intermediary of sleeve portions, extending a fixing shaft through the blades, and fastening the shaft by means of nuts. CONSTITUTION:A rotor 3 of a heat exchanger is supported in a housing 4 in a freely rotatable manner. The rotor 3 is held in contact with a low-temperature fluid in the upper half section of the housing 4, while it is held in contact with a high-temperature fluid in the lower half section, thus exchanging heat between the low-temperature fluid and high-temperature fluid. Further, a plurality of heat exchanger blades 1 are superposed in parallel to each other with sleeve portions being interposed therebetween, and a fixing shaft B is extended through the heat exchanger blades 1. The heat exchanger blades 1 fixed securely in place by tightering nuts on the opposite sides of the shaft B. |
