PURPOSE:To increase the heat exchanging rate of a heat exchanger, by constituting the heat exchanger so that the primary and the secondary air flows can freely flow through the same air-flow paths, and that the state of air flow in the small through-holes on a partition board becomes a turbulence or to be the distance of an approach run for the air flow, utilizing high workability and moisture absorption characteristics of fibrous material such as pulp and asbestos. CONSTITUTION:A partition board is constituted so that the primary and the secondary air flows can contact to each other in the state of turbulence or within the distance of an approach run on the partition board as a whole. The blast of the primary air flow A and the secondary air flow B are fed into small through-holes 4, consisting of a partition board 1 and a number of spacer sheets 2'. The primary air flow A and the secondary air flow B being fed into the small through-holes 4 in the first row exchange heat and moisture by the intermediary of a partition board 1. Then the primary air flow A and the secondary air flow B passed through the small through-holes 4, which are now different in the state from the above- mentioned air flows A and B, are mixed with each other in a mixing space 3 which is formed of cut spacer sheets 2, and is fed into the small through-holes 4 in the next row, and heat and moisture are exchanged by the intermediary of a partition board 1 in the same manner. The above- mentioned process is repeated several times, and the primary and the secondary air flows A and B respectively are supplied to be put to use or are discharged from the heat exchanger. |
