PURPOSE:To increase the efficiency of the titled heat exchanger, by constituting the heat exchanger by assembling a rotary heat exchanger part of regenerative heat permeating type on the outer side, and a rotary heat exchanger part of regenerative type on the inside. CONSTITUTION:An air flow A and an air flow B flow into the elements 24 and 25 of a rotary heat exchanger part 16 of regenerative, heat permeating type, flowing out of the openings on the periphery of a heat exchanger, in the upper part of a heat exchanger partitioned into the upper and the lower parts by a bulkhead 29. The inside ends of diaphragms 19, 19 among the element 24 and 25 are positioned close to the outer side from the center of a circle. This structure provides large internal passages. Pressure loss is small in the air flows A and B, so that highly efficient heat exchanging can be taken place in the passages. The air flow B only flows into a rotary heat exchanger part 15 of regenerative type in the center, flowing out of the openings on the periphery of an outer heat exchanger part 16, guided by flow guide members 26. The heat exchanger part 15 has internal passages of which diameters are equal both in the center part and on the outer periphery, so that the air flow B can flow uniformly and heat is accumulated uniformly as well. When a heat exchanger body rotates and comes to a position in the lower part divided by a partition plate 29, the air flows A and B are changed reversely, and are circulated to the elements 24 and 25 of a heat exchanger part 16. |
