BACKGROUND OF THE INVENTIONField of the Invention
The present invention relates to a total heat exchanger, and in particular to a total heat exchanger with a total heat exchanging core disposed on a side thereof.
Description of the Related Art
In conventional total heat exchangers, a total heat exchanging core is disposed in the central portion of the total heat exchanger, and fans are disposed on two sides of the total heat exchanging core to impel the air flow. The fans are disposed in an upright position. The total heat exchanging core exchanges the heat and the moisture with the air flow, and recycles energy.
In conventional total heat exchangers, the dimensions of the fans are restricted by the dimensions of the total heat exchanging core. The small fans produce noise, and cannot generate sufficient rates of flow. However, if the dimensions of the fans are increased, the dimensions of the total heat exchanging core and the whole total heat exchanger are increased. Additionally, the capability of the total heat exchanging core cannot be sufficiently exerted.

In one embodiment, the housing further comprises a third side wall and a fourth side wall. The first side wall faces the second side wall. The third side wall faces the fourth side wall. The first inlet is formed on the third side wall. The second inlet is formed on the fourth side wall.
In one embodiment, a first flow enters the total heat exchanger through the first inlet, passes through the first inlet chamber, the total heat exchanging core and the first fan, and leaves the total heat exchanger through the first outlet. A second flow enters the total heat exchanger through the second inlet, passes through the second inlet chamber, the total heat exchanging core and the second fan, and leaves the total heat exchanger through the second outlet.
