Description

Heat exchanger assembly for air conditioner {HEAT EXCHANGE STRUCTURE IN AIR CONDITIONER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to a heat exchange element assembly which enables more efficient heat exchange between inlet air and outlet air passing through an air conditioner.

An air conditioner is a device that adjusts a certain indoor space to a temperature, humidity, and airflow distribution suitable for human activity, and removes dust in the air at the same time. Generally, a concept including an air conditioning and heating device. Used as

According to the present invention, in order to increase the efficiency of an air conditioner, the inside and outside air is prevented from being directly mixed while maximizing the mutual contact of the inside and outside air, while minimizing the temperature difference between the outside air. It relates to a heat exchange element of the structure to be able to.

1 is a perspective view schematically showing the structure of an air conditioner 1 in which a heat exchange element assembly 10 is mounted, and FIG. 2 is a perspective view showing the structure of the heat exchange element assembly 10 in detail.

As shown, the heat exchange element assembly 10 for the air conditioner forms a plurality of rectangular diaphragms 11 mounted as a stacked structure at predetermined intervals, and a one-way air passage 13 for each space between the diaphragms 11. On the upper surface of each partition 12 such that a plurality of partitions 12 connecting both sides of each partition 11 and a projection surface in the direction of each air flow path 13 form a wave shape. In addition to having a heat transfer area enlargement portion 14 provided as a corrugated plate structure, each partition 12 connects the two opposite sides of each of the diaphragms 11 to each layer, thereby allowing each air passage 13 to be mutually connected to each layer. It has a structure formed at right angles and repeatedly.

Therefore, as shown in FIG. 2, when air of different properties passes through the heat exchange element assembly 10 through different air flow paths 13A and 13B, these air flows through the diaphragm 11 constituting each layer. Although not directly mixed by the bulkhead 12 and the partition wall 12, the mutual heat transfer is actively progressed as the contact area is enlarged by the diaphragm 11 and the heat transfer area expanding portion 14, so that the air having different properties The temperature difference between the air while passing through the heat exchange element assembly 10 can be minimized.

The heat exchange element assembly 10 having this structure is mounted on the air conditioner 1 as shown in FIG. 1, and indoor and outdoor air passes vertically through the heat exchange element assembly 10 by a blower fan (not shown). While the heat exchange as described above, the contaminated indoor air is discharged to the outside and the fresh air is introduced into the room, while achieving the basic purpose of air conditioning, while the air flow is made in a state where the temperature difference between both air is minimized. In order to ensure efficient operation of air conditioning systems.

That is, when the indoor temperature is to be maintained higher than the outdoor, such as in winter, heat contained in the outflowing air is transferred to the air introduced by the heat exchange element assembly 10, thereby saving driving of the heating device. If the indoor temperature is to be kept low compared to the outdoor, such as in summer, the heat contained in the incoming air is transferred to the air discharged by the heat exchange element assembly 10, thereby saving the driving of the cooling device. It can be.

FIG. 3 shows the structure of each layer of the heat exchange element assembly 10, and includes the diaphragm 11, the partition 12, and the heat transfer area enlargement portion 14 constituting one heat exchange element.

As shown, the heat transfer area enlargement portion 14 is formed as a corrugated plate structure such that the projection surface has a wave shape of a uniform wavelength 14a in the direction of the air flow passage 13, and the air passing through the air flow passage 13 is Indirect contact with the air passing through the adjacent air passages 13a and 13b causes heat transfer.

Since heat transfer occurs more actively as the temperature difference between the two mediators increases, in the structure shown in FIG. 3, air is provided at the inlet side (the left side of FIG. 3) as compared to the outlet side (the right side of FIG. 3) of the adjacent air flow paths 13a and 13b. The heat transfer to the air passing through the flow path 13 is active.

By the way, in the structure of the conventional heat exchange element assembly, the structure which uniformly forms all the wavelengths 14a which comprise the wave-shaped projection surface of the heat transfer area expansion part 14 without considering the above aspect is efficient. It has been criticized for not being a structure.

It is an object of the present invention to provide a heat exchange element assembly which can more efficiently exchange heat between inflow air and outflow air passing through an air conditioner.

In order to achieve the object described above, the present invention provides a plurality of rectangular diaphragms mounted as a laminated structure at predetermined intervals, and connecting both sides of each diaphragm to form a one-way air passage for each space between the diaphragms. And a plurality of partitions and a heat transfer area enlargement portion provided as a corrugated plate structure on the upper surface of each of the partitions such that the projection surface in the direction of each air flow path forms a wave, and the partitions have different sides of the partition for each layer. In a heat exchanger assembly for an air conditioner, wherein the air passages are repeatedly formed at right angles to each layer by connecting sides, the air passages have a wavelength forming a wave projection surface of the heat transfer area enlargement portion adjacent to the air passages. The non-uniform heat transfer area enlargement is formed to become narrower toward the outlet from the inlet of the The present invention provides a heat exchange element assembly for an air conditioner.

Here, the non-uniform heat transfer area enlargement portion may be formed only in the air passages facing a specific direction of each of the air passages, or may be formed in all the air passages.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the heat exchange element assembly for an air conditioner according to the present invention is basically a plurality of rectangular diaphragms 11 mounted as a laminated structure at predetermined intervals, and between each diaphragm 11. A plurality of partitions 12 connecting both sides of each diaphragm 11 so as to form a one-way air passage 13 for each space, and a projection surface in the direction of each air passage 13 form a wave shape. In addition to having a heat transfer area enlarged portion 14 provided as a corrugated plate structure on the upper surface of each partition 12 to form, each partition 12 is connected to each other by the opposite side of each partition 11 for each layer The air flow path 13 is the same as the conventional structure in that it takes a structure repeatedly formed at right angles to each layer.

However, as shown in Fig. 4, the wavelength 100a at which the air flow path 13 forms the wavefront projection surface of the heat transfer area enlargement portion is the inlet port of the adjacent air flow paths 13a and 13b of the air flow path 13 (Fig. It has a characteristic in that it comprises a non-uniform heat transfer area enlargement part 100 formed so as to become narrower toward the outlet direction (right side of FIG. 4) from the left side of 4).

That is, in the heat exchange element assembly according to the present invention, heat transfer is more actively occurring as the temperature difference between the two mediums increases, so that the inlet side (the right side of FIG. 4) is compared with the outlet side (right side of FIG. 4) of the adjacent air flow paths 13a and 13b. On the left) bar heat transfer to the air passing through the air flow path 13 will be actively generated, the wavelength of the heat transfer area expansion portion 100 corresponding to the inlet side (100a) is formed wider than the outlet side of the air By increasing the flow amount, more heat transfer is possible.

In addition, the heat exchange element assembly according to the present invention has a structure in which each air passage 13 is repeatedly formed at right angles to each layer by connecting the two opposite sides of each of the partition plate 11 for each layer. The non-uniform heat transfer area expansion part 100 may be formed only in the air flow paths facing a specific direction among the respective air flow paths, or may be formed in all the air flow paths.

Other structures and working principles are the same as the conventional structures.

That is, as shown in FIG. 2, when the air having different properties passes through the heat exchange element assembly 10 through the different air flow paths 13A and 13B, these air flows through the diaphragm 11 constituting each layer. Although not directly mixed by the bulkhead 12 and the partition wall 12, the mutual heat transfer is actively progressed as the contact area is enlarged by the diaphragm 11 and the heat transfer area expanding portion 14, so that the air having different properties While passing through the heat exchange element assembly 10, the temperature difference between the air can be minimized.

The heat exchange element assembly 10 having this structure is mounted on the air conditioner 1 as shown in FIG. 1, and indoor and outdoor air passes vertically through the heat exchange element assembly 10 by a blower fan (not shown). While the heat exchange as described above, the contaminated indoor air is discharged to the outside and the fresh air is introduced into the room, while achieving the basic purpose of air conditioning, while the air flow is made in a state where the temperature difference between both air is minimized. In order to ensure efficient operation of air conditioning systems.

That is, when the indoor temperature is to be maintained higher than the outdoor, such as in winter, heat contained in the outflowing air is transferred to the air introduced by the heat exchange element assembly 10, thereby saving driving of the heating device. If the indoor temperature is to be kept low compared to the outdoor, such as in summer, the heat contained in the incoming air is transferred to the air discharged by the heat exchange element assembly 10, thereby saving the driving of the cooling device. It can be.

As shown in FIG. 4, the heat transfer area enlargement part 100 is formed as a corrugated plate structure such that the projection surface has a wave shape of non-uniform wavelength 100a in the air flow path 13 direction. The passing air is indirectly in contact with the air passing through the adjacent air passages 13a and 13b to generate heat transfer.

In particular, in the heat exchange element assembly according to the present invention, since the inlet side is wider than the outlet side of the adjacent air passages 13a and 13b, the wavelength 100a is formed on the inlet side of the adjacent air passages 13a and 13b. Since the flow amount of the air passing through the corresponding air flow passage 13 is further increased, more heat transfer can be obtained, and the effect of increasing the thermal efficiency as a whole can be obtained.

The present invention provides a heat exchange element assembly for more efficient heat exchange between the inlet air and the outlet air passing through the air conditioner.
