Description

  The present invention relates to an outdoor unit of a separation type air conditioner having an end plate for fixing a heat exchanger.

  Conventionally, an outdoor unit of this type of separation-type air conditioner is configured by integrally forming metal end plates provided at both ends of a fin in addition to a U-shaped copper tube and fins as a heat exchanger. There are some which are configured to be fixed to the outer box bottom plate or the outer box side plate with screws (for example, see Patent Document 1).

  Further, the heat exchanger is composed of one or a plurality of rows depending on the heat exchange capability required by the air conditioner, and is often installed by bending into an L shape or a U shape. When the heat exchanger is composed of a plurality of rows, the length of the outer row and the inner row of the heat exchanger is different. Therefore, the end plate on the closed side of the U-shaped copper tube is installed separately in the outer row and the inner row. Resin the U-shaped copper tube in the outer row and the U-shaped copper tube in the inner row after the end plate is installed only in the outer row and bent into the L or U shape after being bent into the U shape In some cases, the band was bound together.

  FIG. 8 is a plan view in which a part of the outdoor unit of the conventional separation-type air conditioner described in Patent Document 1 is omitted, and FIG. 9 is a part of the outdoor unit of the conventional separation-type air conditioner is omitted. It is a perspective view.

8 and 9, the outdoor unit 1 is provided with an outer box bottom plate 2, an outer box left side plate 3, an outer box right side plate 4, an outer box front plate 5, and an outer box top plate (not shown) on the exterior. The partition plate 6, the blower 7, and the compressor 8 are installed therein, and the L-shaped heat exchanger 10 sandwiched between the end plates 9 a, 9 b, and 9 c is attached to the rear and left sides of the outer box bottom plate 2 with screws 11. It was fixed and constituted by. The heat exchanger 10 has U-shaped copper tubes 10a and 10b and fins 10c and 10d.

With this configuration, the outdoor unit fixed the internal heat exchanger and was able to hold the heat exchanger without damage during transportation or air conditioning operation.

  Accordingly, it is an object of the present invention to realize an outdoor unit that is cheaper and easy to assemble by reducing only the end plate with a simple structure, thereby reducing loss cost and further reducing the number of parts.

  The outdoor unit of the separation-type air conditioner according to the present invention can reduce the loss cost and the number of parts with a simple structure, and can realize an outdoor unit that is cheaper and easy to assemble.

  In order to sandwich and fix the U-shaped copper tube on the side where the U-shaped copper tube of the heat exchanger is closed, the vertical surface portion along the U-shaped copper tube and the vertical surface portion. By installing and configuring an elastic arm and an end plate provided with claws to fix the U-shaped copper tube in a detachable manner, it is possible to replace only the end plate with a simple structure, thereby reducing loss costs, assembly and market Can be easily repaired.

  In the second invention, when the heat exchanger is constituted by a plurality of rows, in particular, by constituting the number of U-shaped copper tubes held in the outermost row in the end plate of the first invention. Even if the shape of the end plate is reduced, by maintaining the holding force of the copper tube, the material of the end plate can be reduced, and it can be realized at a lower cost.

  In particular, the third invention can be realized at a lower cost by reducing the influence of deformation or the like due to the difference in thermal expansion associated with the difference in heat capacity, by providing a plurality of end plates according to the first or second invention. be able to.

  In the fourth invention, when the heat exchanger is constituted by a plurality of rows, in particular, the end plate of any one of the first to third inventions is arranged between rows so that adjacent fins of the heat exchanger do not contact each other. By using the configuration in which the distance is set, the contact sound of the fins can be reduced.

  In the fifth invention, the structure can be strengthened by extending a part of the end plate and bringing it into contact with the plate constituting the outer box.
