  Conventionally, an air conditioner (air conditioning equipment), cooling equipment, and refrigeration equipment (hereinafter collectively referred to as cooling equipment) has been equipped with a heat exchanger (also referred to as a condenser section, hereinafter) in the housing of the outdoor unit. There is something. In order to cool the cooling facility in the summer, etc., the refrigeration cycle is operated so that the indoor unit releases cool air while taking heat from the heat exchanger in the outdoor unit.

  In that case, there is a water spray device for the outdoor unit for cooling equipment for spraying or sprinkling water on the heat exchanger of the outdoor unit in operation and using the cooling effect of the heat of vaporization to improve the efficiency of the heat exchanger. Various developments have been made.

  As a conventional technique for mounting the water spray device outside the housing of the outdoor unit, Patent Documents 1 and 2 disclose that a frame for attaching a spray body is screwed to the housing.

  On the other hand, in Patent Document 3, a suction inlet of a heat exchanger is provided on both front and back side surfaces of a housing that houses a heat exchanger of an outdoor unit. An auxiliary cooling device is provided so as to face each other. Each auxiliary cooling device is composed of a cooling mat facing the suction inlet, a frame frame that fixes the periphery of the cooling mat, and a water sprinkler that is disposed horizontally at the upper end of the frame frame, for flowing and supplying water to the cooling mat. It has water supply means.

And it attaches so that the vibration isolator 15 may contact | abut the corner | angular part of the front board 2a and the right side board 2c.

[Means for pressing (fixing) the frame (gate frame) to the housing]
A nut 16 is welded to the outer side surface (or inner side surface) of the pressing side frames CT2 and CT4 (the other frame in the claims) comprising the hollow prismatic frame CU, and the through hole 17 corresponding to the female thread portion of the nut 16 is pressed to the pressing side. The frames CT2 and CT4 are drilled (see FIG. 5). Then, a pressing block 19 having a plate-like vibration-proofing member 20 attached to a portion in contact with the left side plate 2 b is pressed against the left side plate 2 b with a pressing bolt 18 screwed into the nut 16. In this case, in order to prevent the lower end side of the pressing side frames CT2 and CT4 from being deformed away from the left side plate 2b by the pressing reaction force of the pressing bolt 18, a line between the pressing side frames CT2 and CT4 and the horizontal reference frames CY1 and CY2 is not used. The connection is made using a different frame DB (see FIGS. 1 and 2). As another embodiment, both ends of the horizontal connection frame YR are connected to the lower ends of the reference vertical frame CT1 and the pressing side frame CT2 by bolts and nuts 21 (see FIG. 1).

A spring 26 may be interposed. Thus, by inserting the vibration isolating members 15, 20 and the compression coil spring 26 in the pressing means, even if the housing 2 vibrates during operation of the heat exchanger or the electric fan 6, vibration is not transmitted to the frame 10, There are effects that the mounting direction of the spray body 12 to be described later is not inadvertently displaced and that other bolt fastening points can be prevented from loosening. Furthermore, since the vibration isolating members 15 and 20 are in contact with the plate of the housing 2, it is possible to reliably prevent the coating of the plate of the housing 2 from being peeled off or the plate surface from being damaged.
Further, as described above, when the housing 2 is fixed so as to sandwich the outer side of the housing 2 with a fixed frame assembly made of a gate-shaped frame, the present invention can be applied to models having different height dimensions of the housing 2 and horizontal dimensions (longitudinal direction) of the front plate 2a. As the pressing means, a portal fixed frame assembly, a pressing bolt 18 screwed to one of the pressing side frames CT2 and CT4, and a pressing block 19 with a vibration isolating member 20 are constituent parts, and the configuration is extremely simple.
