The refrigeration cycle is composed of a compression-condensation- It is possible to circulate a series of processes and supply the indoor air to the room after the heat exchange with the refrigerant.

The compressor 20 compresses and discharges the refrigerant gas in a state of high temperature and high pressure, and the discharged refrigerant gas flows into the heat exchanger 100. The condenser condenses the compressed refrigerant into a liquid phase and releases heat to the surroundings through the condensation process.

The expansion valve (30) expands the liquid refrigerant in the high-temperature and high-pressure state condensed in the heat exchanger (100) into the liquid refrigerant in the low-pressure state. The evaporator (40) evaporates the refrigerant expanded in the expansion valve (30). The evaporator 40 achieves the refrigerating effect by heat exchange with the object to be cooled by using the latent heat of evaporation of the refrigerant, and returns the low-temperature low-pressure refrigerant gas to the compressor 20.

The air conditioner may include an accumulator (60) for separating the liquid from the gas-liquid mixed refrigerant through the evaporator (40) and allowing only the gas refrigerant to flow into the compressor (20). The air conditioner can harmonize the air in the indoor space through the refrigerant pipe (70) connecting the devices so as to form one closed circuit.

The outdoor unit (1) of the air conditioner refers to a portion composed of the compressor (20) and the heat exchanger (100) during the cooling cycle. The expansion valve 30 may be located either in the indoor unit or the outdoor unit 1, and an evaporator (indoor heat exchanger) 40 is located in the indoor unit.

The heat exchanger 100 and the indoor heat exchanger 40 may operate as a condenser or an evaporator depending on the purpose of air conditioning. 1, the heat exchanger 100 of the air conditioner according to the present invention functions as a condenser to condense the refrigerant compressed in the compressor 20, and the indoor heat exchanger 40 It functions as an evaporator and exchanges heat with indoor air to achieve cooling effect.

In the case of the heating purpose, the heat exchanger 100 serves as an evaporator, the indoor heat exchanger 40 serves as a condenser, and the refrigerant is condensed in the room, thereby achieving a heating effect.

Depending on the size of the refrigerant or the capacity of the air conditioner, a plurality of compressors 20 may be provided.

Since the refrigerant transferred from the compressor 20 to the heat exchanger 100 is heat-exchanged with the outside air introduced into the inlet 15, the refrigerant is more likely to be discharged from the outdoor unit 1 as the area of contact between the heat exchanger 100 and the air becomes wider. The efficiency can be improved.

Therefore, the heat exchanger 100 may be provided so as to face the inner surface of the housing 10 to widen the contact area with the air. In particular, to correspond to the inner surface corresponding to the suction port 15.

The air blowing unit cover 250 may be provided in parallel with the upper end of the housing 10 at the upper end of the diffuser 240. The air blowing unit cover 250 may be extended to the side where the first long side 11 and the second long side 13 are offset to be supported on the upper side of the housing 10.

The air blowing unit cover 250 has a structure for covering the upper side of the housing 10 so as to restrict the airflow to the upper side of the housing 10 except the discharge port 16, the bell mouth 230 and the diffuser 240 .

Hereinafter, the structural arrangement of the heat exchanger 100 and the air blowing unit 200 will be described in detail in order to increase the efficiency of the outdoor unit 1.

In order to increase the efficiency of the outdoor unit 1, there is provided a heat exchanger 100 having a large-diameter blowing fan 210 and a large contact area with the air so that a large amount of air can heat- .

Therefore, a method of increasing the efficiency of the outdoor unit 1 in the housing 10, which is provided at a predetermined size by restriction on the place where the outdoor unit 1 is installed, has a maximum diameter that can be provided inside the housing 10 And a heat exchanger 100 having an air blowing fan 210 and a blowing fan 210 disposed inside the housing 10 in a state where a contact area with the air is maximized.

5, in order to maximize the length of the diameter R of the air blowing unit when the length b of the long side of the housing of the present invention is fixed to a predetermined length, the length b of the long side of the housing, (A) of the heat exchanger to the sum of the diameters (R) of the heat exchanger.

When the first blowing unit 211 and the second blowing unit 212 are disposed in the housing 10 in parallel to each other with the two blowing units 200 as in the embodiment of the present invention, ) Is a value obtained by adding the diameter (R + R) of the two blowing units and the thickness (a) of the heat exchanger (b = R + R + a).

However, there may actually be a gap between the diameter R of the blowing unit and the thickness a of the heat exchanger. This distance corresponds to a length that can be excluded from the length (b) of the long side of the bar housing which is the minimum separation provided for the heat exchanger (100) and the blowing unit (200).

The length b of the long side may be set to a length of (R * n) + a when the number of the blowing units 200 is more than n, unlike the embodiment.

This is because the diameter R of the air blowing unit is maintained in the maximum length within the length b of the long side of the housing defined by a predetermined length so that the suction amount of the air to the inside of the housing 10 is maximized So that the efficiency of the outdoor unit 1 is increased.

The diameter R of the air blowing unit may be set to the length of the diameter of the proximal portion 231 which is the inner circumferential surface of the bell mouth 230 closest to the outermost periphery of the blowing fan 210. [ The larger the diameter R of the air blowing unit is, the larger the diameter of the blowing fan 210 is, and the more the amount of air flowing into the housing 10 can be increased.

The distance between the proximal portion 231 and the outermost circumferential surface of the blowing fan 210 may be preferably set to be about 10 mm or so.

The height of the heat exchanger 100 may correspond to the vertical height of the housing 10. This is to maximize the area in contact with the heat exchanger 100 and the air.

And a bending portion 104 bent to connect the first heat exchanger 101 to the second heat exchanger 102 and the second heat exchanger 102 and the third heat exchanger 103.

The heat exchanger 100 according to an embodiment of the present invention may include the first heat exchanger 101, the second heat exchanger 102 and the third heat exchanger 103 without the bend 104, ) May be provided as three or more heat exchangers (100).

The first heat exchanger unit 101 and the third heat exchanger unit 103 are provided facing each other with a space therebetween, but they may be asymmetric in length. This is to ensure a length in which the mounting portion (c) to be described later is provided.

The length of the second long side 13 except for the length of the third heat exchanger 103 may be provided with a mounting portion c.

The installation section c is a space in which the blowing unit 200 is inserted and removed so that the blowing unit 200 is inserted into the inside space formed by the heat exchanger 100 together with the second short side 14.

Since the heat exchanger 100 is provided outside the blowing unit 200 so as to surround the housing 10 in order to increase the efficiency of the heat exchanger 100, It is necessary to have a space to be in and out of the inside of the housing 100.

When the first heat exchanger 101 and the third heat exchanger 103 are provided symmetrically, the space through which the air blowing unit 200 enters and exits is provided only on the second short side 14 side.

Since the size of the diameter R of the air blowing unit is maximized in the length b of the long side of the housing in order to maximize the efficiency of the air blowing unit 200, ) May not be able to access.

The third heat exchanger unit 103 is shorter than the second long side 13 in order to secure the space for the air blowing unit 200 and the blower unit 200 is connected to the heat exchanger 100 A space in which the mounting portion c, which is an insertion / exit space that can be inserted inward, can be formed.

The mounting portion c may be provided with a length corresponding to a minimum space through which the air blowing unit 200 can be inserted and removed. The length obtained by subtracting the length of the mounting portion c from the length of the second long side 13 is referred to as a third heat exchange It can be the length of the donation.

Accordingly, the third heat exchanger unit 103 may be shorter than the first heat exchanger unit 101 in the longitudinal direction.

At this time, unlike the first blowing unit 211, the heat exchanger 100 is not provided at one side of the second blowing unit 212, so that a relatively larger space can be secured. Therefore, unlike the embodiment of the present invention, the diameter of the second blowing unit 212 may be larger than the diameter of the first blowing unit 211.

As the diameter of the second blowing unit 212 is increased, the diameter of the blower 210 is increased and the amount of the air can be further increased, so that the efficiency of the outdoor unit 1 can be increased.

Also, unlike the embodiment of the present invention, when there are two or more blowing units 200, at least one blowing unit 200 may be a part of the first heat exchanging unit 101 like the first blowing unit 211 The second heat exchanger unit 102 and the third heat exchanger unit 103 and at least one of the other blower units 200 may have a structure corresponding to another part of the first heat exchanger unit 101 .

The length b 'of the long side of the housing may be extended by the length of the thickness a of the second heat exchanger in the length b of the long side of the housing shown in the above embodiment.

Therefore, the lengths of the first and second short sides 12 'and 14' are the same, but the lengths of the first and second long sides 11 'and 13' are longer than the thickness a of the heat exchanger, .

The second heat exchanger 110 is installed on the side of the second short side 14 after the air blowing unit 200 is inserted into the heat exchanger 100 through the second short side 14 and the installation part c, .
