Description

Air guide integrated evaporative cooler and its manufacturing method

The present invention relates to an air guide integrated evaporative cooler and a method of manufacturing the same, and more particularly, to an air guide integrated evaporative cooler and a method of manufacturing the same that can be applied to an evaporative cooling and dehumidification apparatus.

An air conditioner, which is a commonly used cooling and dehumidifying device, uses a refrigerant and is recognized as a major culprit of ozone layer destruction and global warming due to leakage of the refrigerant. In consideration of the problem of using the refrigerant, energy ventilators have been developed to reduce the ventilation load through the sensible and latent heat transfer between indoor exhaust and outdoor intake air.

However, the conventional ventilators have a problem that the latent heat recovery rate is significantly lower than the sensible heat recovery rate and cannot cope with an increase in cooling load. In consideration of the problems of the conventional energy ventilator, regenerative evaporative cooling technology has been developed.

Regenerative evaporative cooling technology lowers the temperature of the air by using the evaporative cooling effect of water, and solves the problems of the existing air conditioner because it does not use a refrigerant other than water, and has the advantage of sufficiently reducing the cooling load. have.

The cooler applied to such a regenerative evaporative air conditioner has a wet channel and a dry channel formed continuously and repeatedly. The dry channel passes through a mixture of indoor and outdoor air, and extracts a portion of the air passing through the dry channel through the wet channel in which the water is moistened to induce the evaporation of water. When water evaporates from the surface of the wet channel, the surface of the wet channel is cooled to absorb heat from the air passing through the dry channel, and the air passing through the dry channel is cooled and supplied to the room. In the heat exchange part between the dry channel and the wet channel, a plurality of repeated bent pins are used to increase the contact area.

At this time, the wet channel for supplying the bleed air and the dry channel for supplying the cooled indoor air should be completely separated from each other. To this end, air guides for the wet channel and the dry channel are installed at the lower and upper portions of the structure in which the wet channel and the dry channel are alternately formed.

In this example, Korean Patent No. 10-1055668 discloses a unit module (heat exchange part of the present invention) which is connected to the dry channel part and the wet channel part repeatedly arranged, and is formed at the outlet side of the wet channel part to separate the bleed air from the indoor air. It is configured to include a wet channel guide duct, characterized in that it further comprises a coupling portion for fitting the guide duct (air guide of the present invention) inside or outside the wet channel portion.

However, in this way, the dry channel unit and the wet channel unit are separately made and joined to form a unit module, and the method of combining the air guides with the upper and lower parts of the unit module again requires manufacturing each component separately, and a process requiring assembling thereof is required. Therefore, the manufacturing cost is increased, and in particular, leakage may occur between the unit module and the air guide, or the mixing efficiency of the bleeding air and the indoor air of the wet channel and the dry channel may be degraded.

In particular, the dry channel portion and the wet channel portion include fins having a corrugated cross section (multiple bent), which can be expected to be difficult to manufacture and costly.

In addition, Korean Patent No. 10-1207551 shows a configuration in which a heat exchanger body made of a metal material and a guide member made of a synthetic resin material are combined. Sealing member should be applied between the heat exchanger body and the guide member of the structure to prevent leakage and leakage, but it is not easy to assemble the sealing member, and even if the sealing member is applied, it is difficult to maintain the airtight assembly of the guide member. The evaporated water leaked through the inflow into the dehumidification rotor inside the system is a problem that it is difficult to secure the reliability of the product by causing the cooling capacity and the failure of the rotor.

In the wet channel WC, water and additional air are introduced from the upper left side, and water is evaporated to cool the second partition plate 20, the third partition plate 30, and the second gap portion 60. It cools the air passing through DC).

The second gap portion 60 is a pair of guide portions 61; 61a and 61b for determining a direction in which air flows, and is separated from the guide portion 61 and is diagonal to the second partition plate 20. It consists of a plurality of bars (62; bar) arranged side by side spaced apart at regular intervals in the horizontal direction.

The bars 62 are arranged side by side at regular intervals in a horizontal direction, which is a diagonal direction of the second partition plate 10, which is the same direction as the bars 52 of the first gap portion 50 constituting the dry channel DC. It is.

The bar 62 may be formed in a pipe shape having a rectangular cross section as a hollow inside. One side of the bar 62 is in contact with the second partition plate 20, and the other side is in contact with the third partition plate 30. Water and bleed air passing through the wet channel WC flow through the space 63 between the neighboring bars 62 and the interior space of the bar 62 which is hollow. The bar 62 increases the surface area of the wet channel heat exchanger 64 in place of the conventional fins to allow for a smooth heat exchange.

Since the water and the bleed air supplied to the wet channel WC should be completely separated from the dry channel DC, the guide portion 61 of the second gap portion 60 is opened so that the upper left and lower right sides of the second gap portion 60 are open in the drawing. It is provided to contact the circumference of the second partition plate (20).

The plurality of reliefs 31 may have a difference in a protruding direction, and may be configured to alternately project the upper and lower reliefs 31 up and down.

As such, the second partition plate 20, the second gap portion 60, and the third partition plate 30 constituting the wet channel WC exchange heat with a position where the bar 62 of the second gap portion 60 is in contact with each other. The portion 64 is formed, and the other portion forms the air guide portions 65 and 66 which determine the flow direction of the water and the bleed air. The heat exchange portion 64 and the air guide portions 65 and 66 are integrally formed. It is formed to be able to prevent the leakage and leakage occurs between.

In the wet channel WC and the dry channel DC, the flow direction of the fluid is opposite to 180 degrees in the heat exchange parts 54 and 64 and orthogonal in the air guide parts 55, 56, 65 and 66. In general, a counterflow flow is formed. In addition, the wet channel WC and the dry channel DC may further increase the heat exchange efficiency by preventing leakage and leakage of fluid into the counter flows. This is because the outside air having a high temperature passing through the dry channel DC can be prevented from entering the low temperature wet channel WC.

The second partition plate 20, the second gap portion 60 and the third partition plate 30 form a wet channel (WC), the first gap portion in contact with the opposite surface of the third partition plate (30) The 50 and the fourth partition plate 40 form a dry channel DC again.

The manufacturing method of the evaporative cooler 100 is demonstrated.

First, the first to fourth partition plates 10, 20, 30, and 40 having the same shape are manufactured (step S10).

As shown in FIGS. 1 to 5, first to fourth partition plates 10, 20, 30, and 40 having an octagonal shape having vertices in a rhombus shape are manufactured (step S10). In this case, the first to fourth partition plates 10, 20, 30, and 40 may be manufactured in various ways, and together, the incidences 11, 21, 31, and 41 having a direction in a diagonal direction are formed together.

Next, the guide parts 51 and 61 which contact a part of the edges of the first to fourth partition plates 10, 20, 30 and 40 to determine the flow direction of the fluid are manufactured (step S20).

The guide parts 51 and 61 have been described as forming the dry channel DC and the wet channel WC according to their application, but their shapes are the same.

For convenience of description, the description will be made separately from the step S10, but step S20 may be performed simultaneously with step S10.

Next, the bars 52 and 62 for forming the heat exchange parts 54 and 64 are manufactured (step S30). Step S30 may also be performed simultaneously with steps S10 and S20.

Step S40 to step S60 described below is a step of stacking the components prepared in the step S10 to S30.

First, a plurality of bars 52 positioned between the pair of guide parts 51a and 51b and the pair of guide parts 51a and 51b are arranged on an upper portion of the first partition wall plate 10. The barrier rib 20 is covered to form a dry channel DC (step S40).

Next, a pair of guide portions 61a and 61b and a plurality of bars 62 are arranged on the second partition wall 20, and the guide portions 61a and 61b are arranged in the guide portion ( After arranging the arrays 51a and 51b so as to be rotated 180 degrees, the wet bulkhead WC is formed to cover the third partition plate 30 (step S50).

Next, a pair of guide parts 51a and 51b and a plurality of bars 52 are arranged on the upper part of the third partition plate 30, and the guide part is arranged on the upper part of the first partition plate 10. After the same arrangement as that of 51a and 51b and the plurality of bars 52, the fourth partition plate 40 is covered to form the dry channel DC (step S60).

Thus, the first partition plate 10, the first gap portion 50, the second partition plate 20, the second gap portion 60, the third partition plate 30, the first gap portion 50 and The fourth partition plate 60 is laminated in this order. In this case, the first gap portion 50 and the second gap portion 60 each have bars 52 and 62 which form heat exchange portions 54 and 64 at the same position, and the flow directions of the fluids are diagonal to each other. And guide parts 51 and 52 arranged in a direction (opposite direction in the heat exchange part area and orthogonal direction in the air guide area).

The resultant of the step S60 is put into a heating furnace and bonded to each other by brazing (step S70).

That is, when the resultant of the step S60 is heated to the set temperature, the outer layers of the guide parts 51 and 61 and the bars 52 and 62 made of aluminum 4000 series having a low melting point are melted to form the first partition plate 10 to the fourth. Bonding is made between the partition walls 40.

Therefore, the present invention simplifies the manufacturing process because the partition plates 10, 20, 30, 40 and the gap portions 50, 60 are integrally joined by one brazing without mechanically coupling each other. .

In addition, since the leakage of fluid does not occur between the partition plates 10, 20, 30, 40 and the gaps 50, 60, and a separate mechanical means for fastening is not used, the volume is reduced and manufactured. The increase in cost can be prevented.

It will be apparent to those skilled in the art that the present invention is not limited to the above embodiments and may be variously modified and modified without departing from the technical spirit of the present invention. will be.
