Description

Outdoor Heat Exchanger Condenser of Air Conditioner

The present invention relates to a device for condensing an outdoor heat exchanger of an air conditioner, and in particular, the efficiency of the splashing is improved by installing an auxiliary ring curved in a wave shape in a sprinkling ring that bounces condensate generated during heat exchange in an outdoor heat exchanger to an outdoor heat exchanger. To an outdoor heat exchanger condenser of an air conditioner.

In general, the air conditioner is installed in a window or the like as shown in Figure 1 is provided with a main body 1, the front and rear are exposed to the interior and exterior. The main body 1 is divided into an indoor space portion 1b and an outdoor space portion 1c by a diaphragm 1a, and a diaphragm 1a is provided with a motor 2 for transmitting rotational force in both directions.

In addition, a compressor 5 for compressing the refrigerant at high temperature and high pressure is installed in the outdoor space 1c, and an outdoor heat exchanger 4 for condensing the refrigerant compressed at high temperature and high pressure in the compressor 5 to room temperature is installed at the rear thereof. . The outdoor heat exchanger (4) is provided with a plurality of refrigerant pipes in which the refrigerant flows in a zigzag form, and is provided with heat dissipation fins for radiating heat generated from them to the outside on the outer circumferential surface of each refrigerant pipe.

In addition, a cooling fan 2b is installed at the rear of the motor 2 corresponding to the outdoor space 1c to blow air toward the outdoor heat exchanger 4 to cool the outdoor heat exchanger 4. In addition, the outdoor suction port 4a is formed at both side plates of the outdoor space part 1c, and the outdoor discharge port 4b is formed at the rear of the outdoor heat exchanger 4. Therefore, when the cooling fan 2b is rotated by the driving of the motor 2, the outdoor air is sucked along the outdoor suction opening 4a, and the air is cooled by passing through the rear outdoor heat exchanger 4. In addition, the outdoor air cooled by air is discharged to the outside along the outdoor discharge port (4b).

In addition, the indoor heat exchanger 3 is installed inside the indoor space 1b. The indoor heat exchanger (3) is a refrigerant heat exchanged in the outdoor heat exchanger (4) expands and flows through a capillary tube, and absorbs ambient heat to evaporate the refrigerant, and the ambient temperature decreases while the refrigerant evaporates. Goes. The circulation fan 2a is installed in front of the motor 2 corresponding to the indoor space 1b.

The circulation fan 2a is rotated by the motor 2 which rotates in both directions to circulate the indoor air toward the indoor heat exchanger 3. In addition, the indoor intake port (3a) is installed in the front of the main body 1 by the rotation of the circulation fan (2a) to suck the indoor air toward the indoor heat exchanger (3), and the indoor heat exchanger (3) below the indoor intake (3a) An indoor discharge port 3b through which the cold air cooled by heat exchange while being discharged is discharged into the room is formed.

In addition, the indoor heat exchanger (3) is condensed water is generated by the condensation of moisture contained in the indoor air during the heat exchange process. The condensed water thus generated falls toward the receiving part 6 of the lower part directly and is drained toward the receiving part 6b of the outdoor heat exchanger 4 along the hose 6a. In addition, a watering ring (2c) is formed on the outer circumferential surface of the cooling fan (2b) and a portion of the lower end of the watering ring (2c) passes through the receiving portion (6b).

At this time, the condensed water 7 contained in the receiving part 6b is raised along the watering ring 2c which is rotated and scattered toward the outdoor heat exchanger 4. In addition, the heat dissipation efficiency of the outdoor heat exchanger 4 is improved due to the condensed water 7 scattered.

In the conventional air conditioner configured as described above, when the motor 2 is operated, the circulation fan 2a and the cooling fan 2b installed in both directions thereof are rotated at the same time. In addition, when the refrigerant is compressed at a high temperature and high pressure in the compressor 5 and then circulated toward the outdoor heat exchanger 4, the refrigerant is air-cooled by the wind generated by the rotation of the cooling fan 2b. That is, when the cooling fan 2b is rotated, the outdoor air is sucked into the outdoor space 1c through the outdoor suction opening 4a and then passes through the outdoor heat exchanger 4 at the rear. In addition, after passing through the heat exchanger (4) to cool it is exhausted to the outside along the outdoor discharge port (4b).

In addition, while the refrigerant condensed in the outdoor heat exchanger 4 passes through a capillary tube (not shown), the expanded and expanded refrigerant is circulated toward the indoor heat exchanger 3 of the indoor space 1b. In addition, when the circulation fan 2a is rotated by the driving of the motor 2, the indoor air is sucked into the indoor space 1b along the indoor suction port 3a and then cooled while passing through the indoor heat exchanger 3. In addition, the cooled indoor air is discharged into the room through the indoor discharge port (3b) and the room is cooled.

In addition, when the room is cooled, moisture in the indoor air passing through the indoor heat exchanger (3) is condensed due to the temperature difference, and the condensate (7) is carried by the receiving part (6) and the hose (6a) to receive the outdoor space part (1c). Gather toward the part 6b. When the cooling fan 2b is rotated while the condensate 7 is collected in this manner, the condensate 7 is scattered by the sprinkling ring 2c formed on the cooling fan 2b and bounced toward the outdoor heat exchanger 4. Therefore, the outdoor heat exchanger 4 is air-cooled and water-cooled at the same time to improve the condensation efficiency.

However, since the condensate 7 collected in the receiving part 6b is bounced off the inner circumferential surface of the sprinkling ring 2c in the process of being bounced toward the outdoor heat exchanger 4 through the sprinkling ring 2c, the condensed water 7 ) Has a disadvantage in that the spraying effect is reduced. The sprinkling ring 2c is condensed water (7) buried in the inner circumferential surface in the process of being rotated to the upper side by the surface tension and the condensed water (7) is thus scattered by the centrifugal force.

In addition, the scattered condensate 7 is bounced toward the outdoor heat exchanger 4 by the wind power of the cooling fan 2b, and the outdoor heat exchanger 4 is water cooled. At this time, because the condensate (7) buried in the sprinkling ring (2c) is raised to the upper side by the surface tension, the condensate (7) is not actively heard. In addition, since the condensate 7 that is lifted upward is small, the condensate 7 that is splashed and splashed is reduced, and the heat dissipation effect of the outdoor heat exchanger 4 is reduced.

The present invention was developed in view of the conventional problems, and an object of the present invention is to supply condensate generated during heat exchange of an indoor heat exchanger to an outdoor heat exchanger, and then condensate to be splashed toward an outdoor heat exchanger by a sprinkling ring of a cooling fan. In the condenser unit of the air conditioner to install the pumping member to pull the condensate to the upper portion to increase the amount of condensate lifted to the upper, the water cooling efficiency is improved by the condensate water scattered by the outdoor heat exchanger In providing.
