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.

2. The heat exchanger as claimed in claim 1, wherein the unit module includes a plurality of heat transmitting fins disposed at a prescribed part between a wave-shaped heat lane.

3. The heat exchanger as claimed in claim 2, wherein the unit module has a partition mechanism for dividing the unit module into a heat releasing side and a heat absorbing side.

4. The heat exchanger as claimed in claim 3, wherein 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.

5. The heat exchanger as claimed in claim 4, wherein the receptacle parts have at least one of a water resistant property and an elastic property.

6. The heat exchanger as claimed in claim 4, 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 end part of another plate member.

7. 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.

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

9. A heat exchanger comprising:

a plurality of unit modules, each unit module having an independent heat exchange function and defining a flow path direction therethrough;

wherein the plurality of unit modules are stacked with respect to one another in the flow path direction.

10. The heat exchanger as claimed in claim 9, wherein each unit module includes a partition mechanism, and wherein the partition mechanisms of the stacked unit modules together form a partition part extending in the flow path direction that divides the stacked unit modules into a heat releasing side and a heat absorbing side.

11. A heat exchanger comprising:

a plurality of unit modules, each unit module having an independent heat exchange function and including a position defining mechanism;

wherein the plurality of unit modules are stacked end to end with respect to one another, and the position defining mechanism of one unit module mates with the position defining mechanism of an adjacent unit module to align the adjacent unit modules end to end with respect to one another.

12. The heat exchanger as claimed in claim 11, wherein the position defining mechanism of one unit module mates with the position defining mechanism of an adjacent unit module to form a partition part extending in the end to end direction, the partition part dividing the stacked unit modules into a heat releasing side and a heat absorbing side.

13. A unit module for use in a heat exchanger, the unit module comprising:

a heat exchanging structure defining a flow path direction therethrough; and

a partition mechanism extending in the flow path direction dividing the heat exchanging structure into a heat absorbing side and a heat releasing side;

wherein the partition mechanism includes a receptacle part having a passage and a plate inserted into the passage and secured in the receptacle part.
