Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit installed outside of an air conditioner, and more particularly to an outdoor unit of an air conditioner in which the degree of freedom of an outdoor installation place is increased.

[0002]

2. Description of the Related Art Conventionally, an example of an outdoor unit of this type of air conditioner is disclosed in Japanese Utility Model Publication No. Sho 62-41144. The outdoor unit of this air conditioner has a heat exchanger unit portion and a machine room portion formed up and down by a casing portion. A compressor, an accumulator, and the like are housed in the machine room portion, and a V.V. It houses a heat exchange element and a blower.

[0003] A right-angled triangular ventilation opening is formed in the outer wall surrounding the V-shaped heat exchange element of the heat exchanger unit,
The outside air is introduced from the ventilation port to exchange heat with the V-shaped heat exchange element, and then is released again to the outside from the air outlet on the upper surface.

[0004]

However, in such a conventional outdoor unit of an air conditioner, when, for example, a plurality of such outdoor units are installed side by side in a laterally adjacent manner, adjacent outdoor units are installed. Are opposed to each other, so that the flow rate of suction of outside air from the triangular ventilation port into the heat exchanger unit decreases. For this reason, since sufficient heat exchange cannot be performed with the V-shaped heat exchange element due to a sufficient flow of outside air, the heat exchange capacity is reduced, and the air conditioning capacity is reduced. Also, when the outdoor unit is installed such that the suction port of the heat exchange unit portion is close to, for example, a wall surface such as a building outdoor wall, the outdoor unit is introduced into the heat exchange unit from the suction port close to the wall surface. Since the flow rate of outside air is reduced, the heat exchange capacity of the heat exchange element is reduced. In other words, there is a problem that the heat exchange capacity and, consequently, the air conditioning capacity are reduced depending on the installation location or method of the outdoor unit.

[0005] The present invention has been made in view of such circumstances, and its object is to perform installation while maintaining high performance without reducing the heat exchange capacity, regardless of the installation location or method. It is an object of the present invention to provide an outdoor unit of an air conditioner that can increase the degree of freedom of installation and effectively utilize the installation space.

[0006]

According to the present invention, the pair of opposed sides of the heat exchanger housed in the heat exchange chamber are inwardly formed with respect to the outer peripheral wall of the heat exchange chamber in which the suction port is formed. Is inclined at a predetermined angle, so that one surface of the outer peripheral wall, in which a pair of opposed sides of the inclined outdoor heat exchanger is provided with a suction port facing each other, is proximately opposed to a wall surface such as a building outdoor wall. Even when an outdoor unit is arranged, each opposing side portion of each heat exchanger faces the outer peripheral wall of each heat exchange chamber which is close to and opposes the exterior wall surface of the building and each inner surface of the outer peripheral wall adjacent thereto, respectively. Since the suction space in the gap between the outer peripheral wall of the heat exchange chamber and each opposing side of the heat exchanger is enlarged by the amount that the opposing side of the heat exchanger is inclined inward, each heat exchange The reduction of the outside air suction area of the vessel can be suppressed or prevented. For this,
A decrease in the heat exchange capacity of the heat exchanger can be suppressed or prevented.

Further, even when a plurality of outdoor units are arranged side by side so that one surface of an outer peripheral wall provided with a suction port of a heat exchange chamber is closely opposed to each other, each of the opposed sides of the heat exchangers of both units is arranged. The outer peripheral wall of the heat exchange chamber of each of these units, the outer peripheral wall of the unit and the outer peripheral wall of the unit adjacent to each other, and the inner wall of the outer peripheral wall of the adjacent unit. The suction space of the gap between the opposing sides of each heat exchanger is enlarged by the amount that the opposing sides of each heat exchanger are inclined inward, so that the reduction of the outside air suction area of each heat exchanger is suppressed. Or prevent it. For this reason, a decrease in the heat exchange capacity of the heat exchanger can be suppressed or prevented.

Therefore, even when the outdoor unit has to be installed in a state where one surface of the outer peripheral wall of the heat exchange chamber in which the suction port is formed is close to and facing the outside wall of the building or the like, the outdoor unit is required to be high. It can be installed while maintaining the heat exchange capacity. That is, since the installation can be performed in such a limited space without reducing the heat exchange capacity of the outdoor unit while maintaining high performance, the degree of freedom of installation of the outdoor unit is increased, and the installation space is increased. Can be used effectively.

The invention according to claim 2 is characterized in that the heat exchanger comprises:
2. The outdoor unit of an air conditioner according to claim 1, wherein the pair of inclined sides are arranged substantially in parallel.

According to the present invention, since the pair of inclined opposite sides of the heat exchanger are arranged substantially in parallel with each other, each suction space in the heat exchange chamber is substantially equal to the inclined surface of the opposed sides. Can be secured evenly. For this reason, even when a plurality of outdoor units are arranged side by side close to each other on the left and right sides, a sufficient intake amount of outside air can be ensured, so that a high heat exchange capacity and thus an air conditioning capacity can be maintained.

According to a third aspect of the present invention, in the heat exchanger,
2. A heat exchanger comprising a pair of heat exchangers each formed in an obtuse angle L-shape, each L-shaped side of which is disposed so as to face a suction port of a heat exchange chamber. An outdoor unit of the air conditioner according to Item 2.

According to the present invention, since two inclined surfaces can be formed by a pair of heat exchangers formed in an obtuse L-shape, the outer surface area, that is, the heat exchange area, is smaller than that of, for example, a rectangular heat exchanger. The air conditioning capacity can be increased.

Further, since the heat exchanger is composed of a pair of obtuse angle L-shaped heat exchangers having the same shape, these heat exchangers can be raised and fixed on the partition plate, so that assembly can be simplified, and productivity can be improved. Is good.
