Abstract
Abstract A heat exchanging element for use in a rotary-type counter-current heat exchanger is provided. The heat exchanging element comprises a gathering member composed of natural fiber, especially coconut fiber. And a rotary-type counter-current heat exchanger is provided. The heat exchanger comprises a casing, a rotary frame rotatably supported by the casing, the rotary frame having a shaft, a pair of rotor rims maintaining a predetermined distance in an axial direction of the shaft and a plurality of rotor spokes, and the heat exchanging element accommodated in the rotary frame.

Claim 5
Dependent Claim
105 words
A rotary-type counter-current heat exchanger comprising: a casing; a rotary frame rotatably supported by said casing, said rotary frame including a shaft, a pair of rotor rims maintaining a predetermined distance in an axial direction of said shaft and a plurality or rotor spokes, one end of each rotor spoke being fixed to said shaft and the other end thereof being fixed to said pair of rotor rims, and a heat-exchanging element accommodated in said rotary frame, said heat exchanging element consisting of a gathering member, said gathering member being composed of coconut fiber having a diameter equal to between about 0.1 and 0.4 millimeter.
Claim 6
Dependent Claim
35 words
A rotary-type counter-current heat exchanger as claimed in claim 3, wherein said rotor spoke is plate-like member so that a plurality of said rotor spokes form a plurality of fan-shaped matrixes in said rotary frame.
Claim 7
Dependent Claim
32 words
A rotary-type counter-current heat exchanger as claimed in claim 4, wherein said heat exchanging element is contained in a fan-shaped cartridge, and said fan-shaped cartridge is fitted into each said fan-shaped matrix.
Claim 8
Dependent Claim
32 words
