Description

Heat exchanger for ventilation

The present invention relates to a heat exchanger for a ventilation device for exchanging outdoor air and indoor air.

In general, the ventilation system is a device that discharges contaminated indoor air to the outside and supplies fresh outdoor air to the room, and the ventilation device filters and filters the various harmful substances contained in the outdoor air, and heat exchanges the indoor air and the outdoor air. A heat exchanger is provided to minimize changes in room temperature during ventilation.

Existing heat exchangers for ventilation devices are interposed with the first heat exchanger and the first heat exchanger formed in a corrugated form so as to form a first air passage which is laminated between the heat exchanger plates and is stacked between the heat exchanger plates and the outdoor air passes. It is composed of a second heat transfer member formed in a corrugated form so as to form a second air passage through which the indoor air passes and is stacked between the heat transfer plates.

And on both sides of the heat exchanger, a first barrier rib is installed on both sides of the first air passage, and on both sides of the heat exchanger, a second barrier rib is installed on both sides of the second air passage to provide a first air passage. Block indoor air from entering and block outdoor air from entering the second air passage.

As such, the existing heat exchanger for the ventilation system is manufactured by alternately stacking the first heat exchanger member, the heat exchanger plate, and the second heat exchanger member, thus making the manufacturing process complicated, blocking indoor air from entering the first air passage, and blocking the second air cylinder. Separate first and second bulkheads are required to block the outdoor air from entering the furnace, so the manufacturing process is complicated and costs increase.

In addition, there is a problem in that production costs are increased because welding or the like is required to seal the first and second partition walls so that air does not pass therethrough.

Accordingly, an object of the present invention is to divide the first heat exchange part where the first air passage is formed and the second heat exchange part where the second air passage is formed alternately, so that the first air passage and the second air passage are partitioned, so that the manufacturing process is performed. It is to provide a heat exchanger for a ventilation system which can simplify and reduce manufacturing cost.

According to an embodiment of the present invention, the first heat exchange part in which the first air passage through which the first air passes is formed and the second heat exchange part in which the second air passage through which the second air passes is formed are alternately stacked, and The first heat exchange part may be arranged to surround the flat surface on both sides and upper surfaces of the first corrugated plate formed in a corrugated form so that the first air passage is formed, thereby partitioning between the first air passage and the second air passage.

The second heat exchange unit may be formed of a corrugated second wave plate to form a second air passage.

The first wave plate and the flat plate may be formed of a metal material having excellent heat transfer.

In the flat plate, a lower surface portion is disposed on a lower surface of the first wave plate, and side portions bent at both sides of the lower surface portion are disposed on both side surfaces of the first wave plate, and an upper surface portion bent inward from the side portion is an upper surface of the first wave plate. Can be placed on.

Both ends of the flat plate may be disposed to overlap each other on the upper surface of the first wave plate.

Both ends of the flat plate are disposed to overlap each other on the upper surface of the first wave plate, and the overlapped portions can be sealed by adhesion or welding.

Both ends of the flat plate may be placed against the upper surface of the first wave-shaped plate and fixed by an adhesive sheet.

As described above, in the present invention, the first heat exchange portion is disposed so that the flat plate is enclosed on both sides and upper surfaces of the first corrugated plate forming the first air passage, and the second heat exchange portion forms the second air passage. If alternately stacked, the first air passage and the second air passage are partitioned, thereby simplifying the manufacturing process and reducing manufacturing costs.

A first suction port 12 through which the first air is sucked and a second discharge port 14 through which the second air is discharged are formed on one side surface of the case 10, and the first air on the other side surface of the case 10 A first discharge port 16 discharged and a second suction port 18 through which the second air is sucked may be formed.

In addition, two opposite sides of the heat exchanger 20 are connected to the first suction port 12 and the first discharge port 16, and the two opposite sides are connected to the second suction port 14 and the second discharge port 18 As the first air and the second air are crossed, heat exchange between the first air and the second air may be performed. For example, the first air may be outdoor air, and the second air may be indoor air.

As shown in FIG. 2, the heat exchanger 20 is alternately stacked with a first heat exchange part 30 in which a first air passage 22 through which the first air passes is formed, and a first heat exchange part 30. And a second heat exchange part 40 through which the second air passage 24 through which the second air passes is formed, and a fixing member fixing the first heat exchange part 30 and the second heat exchange part 40 which are alternately stacked. It may include 50.

The first air passage 22 and the second air passage 24 are arranged to be orthogonal to each other, and the first air passing through the first air passage 22 and the second air passing through the second air passage 24 are provided. Heat exchange may be performed by the first heat exchange unit 30 and the second heat exchange unit 40.

As shown in FIG. 3, the first heat exchange unit 30 is formed with a first corrugated plate 32 formed in a corrugated form to form a first air passage 22, and an upper surface of the first corrugated plate 32, It may include a flat plate 34 is disposed to surround the lower surface and the side.

The first corrugated plate 32 and the flat plate 34 may be formed of a metal material having excellent heat transfer, and may be made of, for example, aluminum or an aluminum alloy.

The first wave plate 32 may be formed with a convex portion and a concave portion repeatedly to form the first air passage 22. In addition, the flat plate 34 is provided with a lower surface portion 34a and a lower surface portion 34a, which are disposed on the lower surface of the first wave plate 32, and a side portion 34b that is disposed on both sides of the first wave plate 32. , It may include an upper surface portion 34c extending in the inner direction from the side portion 34b and disposed on the upper surface of the first wave plate 32.

At this time, the side portion 34b is located on the side surface of the first wave plate 32 to block both sides of the first air passage 22 so that the first air passing through the first air passage 22 leaks laterally prevent.
