1 to 3 show an embodiment of the present invention. FIG. 1 is a front view of an outdoor unit, FIG. 2 is a right side view of the outdoor unit, and FIG. 3 is a top view of the outdoor unit. FIG. In each figure, white arrows indicate the direction of the intake wind, and solid black arrows indicate the direction of the blown air.

The refrigeration system is composed of an outdoor unit 2 and an indoor unit (not shown) as shown in FIGS. 1 to 3, and both units are connected by unit piping (not shown) to function as a refrigeration system. .

The outdoor unit 2 has a compressor (not shown) therein, a back surface 4C, a left side surface 4B, and a right side surface 4A.
An air-cooled fin tube heat exchanger 9 having a U-shaped horizontal cross section is disposed inside the suction port 11 opposite to the suction port 11 (see FIGS. 2 and 3).

A plurality of blowers 8 and air outlets 6 for sucking outside air toward the fin tube heat exchanger 9 are provided on the front surface 3 and the top surface 5 of the outdoor unit 2, respectively.

A plurality of air outlets 6 are provided in the upper part of the front surface 3 of the outdoor unit 2 (see FIG. 1) so as to be covered with a fan guard 6A. .

The blower 8 comprises a fan motor 8A and a propeller fan 8C, and is fixed to the outdoor unit 2 by a support frame 8B (see FIG. 2).

An outlet 6 covered by a cover 7 for closing the outlet 6 is provided at the lower left of the front surface 3.

A plurality of air outlets 6 are also provided on the top surface 5 (see FIG. 3) of the outdoor unit 2 so as to be covered by a fan guard 6A, and a blower 8 is provided inside the air outlets 6.

The right side surface 4A of the outdoor unit 2 (see FIG. 2)
Is provided with a wiring / pipe port 10 which is a passage for inter-unit piping and electric wiring.

The positions of the plurality of outlets 6 can be relocated according to various conditions of the installation location.

For example, if there is an obstacle on the right side in front of the outdoor unit 2 in FIG. Thus, the outlet 6 at the lower left can be used.

In this case, the cover 7 of the lower left outlet port 6
And the fan guard 6A and the blower 8 of the upper right outlet 6 are removed, the blower 8 and the fan guard 6A removed at the lower left outlet 6 are attached, and the cover 7 removed to the upper right outlet 6 is further attached. What is necessary is just to redo the electric wiring of the blower 8 which was removed.

By doing so, the outdoor unit 2
In the case where there is an obstacle on the right side of the front face 3, it is possible to set the optimal arrangement of the outlet ports 6 by rearranging the outlet ports 6 on the left side of the front face 3.

Although not described in detail here, the air outlet 6 of the front surface 3 and the top surface 5 can be similarly moved.

Further, when using the outdoor unit 2 to develop a refrigerating apparatus having a different refrigerating capacity, the number of the outlets 6 and the number of the blowers 8 can be increased or decreased according to the refrigerating capacity.

FIG. 4 is an explanatory front view of an outdoor unit of a refrigerating apparatus showing another embodiment of the present invention. In another embodiment, a shutter opening / closing device 12 that opens and closes automatically is provided in front of the outlet 6, and is configured to open and close in accordance with the operation of the blower 8. This shutter opening / closing device 12
Is configured to prevent air leakage from the outlet 6 when closed.

As described above, during low-load operation, some of the blowers 8 (for example, the blower 8 on the top surface 5) are stopped to save energy. It is possible to prevent intrusion and improve the appearance.

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the present invention. For example, although the refrigerating apparatus has been described in the above embodiment, it is needless to say that a separate type air conditioner may be used.

[0028]

As described above, according to the first aspect of the present invention, a suction port is provided on at least one surface of a main body having a built-in air-cooled heat exchanger, and the air sucked from the suction port is used to generate heat. In an outdoor unit in which the refrigerant flowing in the exchanger is subjected to heat exchange and the air after the heat exchange is discharged from an outlet provided on a surface different from one surface of the main body, the air is blown to a plurality of surfaces different from the one surface. By providing the outlet, it is possible to improve the arrangement of the air outlets in the outdoor unit and provide an outdoor unit having a sufficient air flow to the heat exchanger.

According to the second aspect of the present invention, one surface is the rear surface of the main body, and the plurality of surfaces different from the one surface are the top surface and the front surface of the main body, thereby improving the arrangement of the air outlets in the outdoor unit. In addition, it is possible to provide an outdoor unit having a sufficient amount of air for the heat exchanger.

According to the third aspect of the present invention, since the blowers are provided in each of the plurality of outlets, the arrangement of the outlets in the outdoor unit is improved, and the outdoor air volume to the heat exchanger is sufficient. Units can be provided.

According to the fourth aspect of the present invention, the positions of the plurality of outlets can be relocated according to the installation conditions, so that the arrangement of the outlets in the outdoor unit is improved, and the number of the outlets is reduced. An outdoor unit with a sufficient air volume can be provided.

According to the fifth aspect of the present invention, the arrangement of the outlets in the outdoor unit is improved by providing a shutter opening / closing device for opening the plurality of outlets in accordance with the operation of the blower. , An outdoor unit having a sufficient airflow can be provided.
