PROBLEM TO BE SOLVED: To provide an inexpensive heat exchanger capable of preventing the impairing of heat exchanging performance caused by clogging of tubes. SOLUTION: A plurality of tube bundle blocks 40 composed of a plurality of tubes 10 communicated with a number of through holes of bases 20, and mounted approximately vertically from surfaces of the bases 20, are mounted between the bases 20 having a number of through holes, the tube bundle blocks 40 are stacked through spacers 30 mounted on the circumference of back faces of the bases 20, mixing chambers 70 are respectively formed between the tube bundle blocks 40, and the tubes 10, the bases 20 and the spacers 30 are integrally molded, thus an area where the internal fluid is not circulated because of clogging of a part of the tube bundles, can be narrowed to the tube bundle one block, and the significant lowering of heat exchanging quantity can be prevented. Further as it is unnecessary to make joining of the tube 10 and the base 20, and the base 20 and the spacer 30 anew, the man hour and costs can be reduced. COPYRIGHT: (C)2006,JPO&NCIPI
