Abstract

A heat exchanger includes a plurality of unit modules aligned in parallel, in which each unit module has a heat exchange function.

Claims

1. A heat exchanger comprising:

a plurality of unit modules aligned in parallel, each unit module having a heat exchange function, wherein

the unit module includes a plurality of heat transmitting fins disposed between waves of a wave-shaped heat lane,

the unit module has a partition mechanism for dividing the unit module into a heat releasing side and a heat absorbing side,

the partition mechanism defines a plurality of spaces disposed within the wave-shaped heat lane, and includes a plurality of receptacle parts selectively insertable into the spaces, and a plurality of plate members selectively insertable into the receptacle parts, and

wherein each of the plate members has a rear end part that protrudes from the receptacle part when inserted into the receptacle part, wherein the receptacle part has a connection part formed at a front end side for receiving the rear part of another plate member.

2. The heat exchanger as claimed in claim 1, wherein the receptacle parts have at least one of a water resistant property and an elastic property.

3. The heat exchanger as claimed in claim 1, further comprising a plurality of holding members for holding the unit modules in the aligned state, wherein the holding members include a fixing mechanism for fixing the unit modules.

4. The heat exchanger as claimed in claim 1, wherein the heat exchanger is disposed at a part of an outer wall of a cabinet.
