Abstract

The purpose of the present invention is to provide an air guide-integrated evaporation cooler which allows a plurality of barrier plates, heat exchangers, and air guides for forming a dry channel and a wet channel to be integrally manufactured by a simple process, and a method of manufacturing the same. The air guide-integrated evaporation cooler for implementing the purpose includes a plurality of barrier plates; and gap units including a plurality of bars positioned between the plurality of barrier plates, disposed to be spaced apart from each other at a center portion thereof, and configured to form heat exchangers, and guides disposed at edges of the plurality of barrier plates and configured to determine a direction of a fluid flow.

First claim

The invention claimed is:

1. An air guide-integrated evaporation cooler comprising:
a plurality of barrier plates; and
gap units including a plurality of bars positioned between the plurality of barrier plates, disposed to be spaced apart from each other at a center portion thereof, and configured to form heat exchangers, and guides disposed at edges of the plurality of barrier plates and configured to determine a direction of a fluid flow,
wherein a counterflow is formed in two adjacent gap units of the gap units with one barrier plate of the plurality of barrier plates interposed therebetween.

2. The air guide-integrated evaporation cooler of claim 1 ,
wherein the plurality of barrier plates include a first barrier plate, a second barrier plate, and a third barrier plate which are spaced predetermined distances from each other;
a dry channel is formed between the first barrier plate and the second barrier plate, wherein indoor air and outdoor air flow through the dry channel; and
a wet channel is formed between the second barrier plate and the third barrier plate, wherein water and exhausted air flow through the wet channel.

3. The air guide-integrated evaporation cooler of claim 2 ,
wherein the gap units are formed with a first gap unit provided between the first barrier plate and the second barrier plate and a second gap unit provided between the second barrier plate and the third barrier plate; and
a fluid flow in the first gap unit is the counterflow of a fluid flow in the second gap unit.

4. The air guide-integrated evaporation cooler of claim 2 ,
wherein a plurality of embossings respectively protrude from the barrier plates in a direction of one side thereof; or
some of the plurality of embossings respectively protrude from the barrier plates in a direction of one side thereof and the remainder thereof respectively protrude from the barrier plates in a direction of the other side thereof.

5. The air guide-integrated evaporation cooler of claim 4 , wherein some of the embossings that protrude toward the dry channel (DC) have lengths in a direction parallel to a flow direction of the indoor air and the outdoor air.

6. The air guide-integrated evaporation cooler of claim 4 , wherein the embossings are in contact with the embossings on another adjacent barrier plate.

7. The air guide-integrated evaporation cooler of claim 1 , wherein pairs of guides are provided at edges of one sides and the other sides of the barrier plates to be opposite each other, and areas thereof in contact with the barrier plates are bonded such that the fluid is introduced through one open sides between the pairs of guides, and the fluid is discharged through the other open sides of the pairs of guides.

8. The air guide-integrated evaporation cooler of claim 7 , wherein the bar includes a plurality of bars spaced predetermined distances in a horizontal direction, which is a diagonal direction of the barrier plates, and arranged in parallel.

9. The air guide-integrated evaporation cooler of claim 1 ,
wherein the guides and the bars are formed of aluminum clad and the outer layers thereof are formed of aluminum having a melting point lower than that of the inner layers; and
the aluminum clad forming the outer layers is melted by heat, and the guides and the bars are integrally bonded to the barrier plates.

10. The air guide-integrated evaporation cooler of claim 1 ,
wherein the plurality of bars are formed to be hollow in a shape of a pipe with a rectangular cross section;
each of one side surfaces and the other side surfaces of the bars is in contact and coupled with adjacent barrier plates; and
the fluid flows through spaces between the adjacent bars and spaces inside the bars.

11. A method of manufacturing an air guide-integrated evaporation cooler,
wherein the air guide-integrated evaporation cooler comprises:
a plurality of barrier plates; and
gap units including a plurality of bars positioned between the plurality of barrier plates, configured to form heat exchangers by being disposed to be spaced apart from each other at a center portion thereof, and formed with inner layers and outer layers formed of clad, and guides disposed at edges of the plurality of barrier plates, configured to determine a direction of a fluid flow, and formed inner layers and outer layers formed of clad,
the method comprising:
operation a) providing the plurality of barrier plates, the bars, and the guides;
operation b) repeating operations of arranging the bars and the guides at an upper portion of one of the plurality of barrier plates, covering the arranged bars and guides with the next barrier plates, and arranging the bars and the guides; and
operation c) heating a component provided through the operation b), melting the outer layers having a melting point lower than that of the inner layers of the guides and the bars, and bonding the barrier plates to the bars and the guides,
wherein, in the operation b), the guides and the bars are arranged such that flow directions of fluids flowing through the adjacent gap units with one of the barrier plates interposed therebetween form counterflow.

12. The method of claim 11 , wherein the guides and bars are formed of aluminum clad.
