Abstract

PURPOSE:To provide a holding piece for holding a pipe body and contrive the simplification of attaching work and the inexensiveness of assembling cost by forming cutting-up parts on a base plate. CONSTITUTION:Six holding pieces 22 for holding a pipe body 11 are integrally stood by forming rectangular cutting-up parts before and behind, left and right, backward center of a baseplate 21. These holding pieces 22 are positioned between two neighboring fins and holding faces 23 for suiting to the peripheral face 11a of the pipe body 11 by forming semi-circular notches A on the upper part thereof. The peripheral face 11a of the pipe body 11 is placed on the holding faces 23 of the holding pieces 22 at the time of attachment and a heat exchanger 8 can be attached to the baseplate 21 in the condition in which the pipe body 11 is held on the holding pieces 22. Since a support for upward and downward extending is not needed for the attachment of the heat exchanger 8, suction resistance can be lessened therefor and effectiveness can be heightened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat exchanger mounting structure suitable for implementation in, for example, an outdoor unit of an air conditioner.

[Conventional technology]

Conventionally, there are mounting structures for this type of heat exchanger as shown in FIGS. 7 to 10. To explain this based on the same figure, in the same figure, what is indicated by reference numeral 1 is a frame-shaped plywood board for an air conditioner outdoor unit, and 2 to 5 are screws 6 attached to the four corners of this base plate 1. There are four pillars erected, front, rear, left and right, 7 is the rear pillar 4.5 of these pillars 2 to 5.
Supports 8 and 9 are erected between them by screws 6, and are fixed to this support 7 and the above-mentioned supports 2 to 5 by screws 6, and have rectangular fins 10 for pipe insertion and tube bodies 11 for heat exchange. Heat exchanger, 12, these heat exchangers 8
, 9 is an upper panel provided by screws 6 and has an air passage duct 13; 14 is a mounting base provided on the back side of this upper panel 12 and has a mounting surface 15 below said air passage duct 13; 16 is this upper panel; A blower 1 fixed on a mounting surface 15 of a mounting base 14 and consisting of a motor 17 and a fan 18;
Reference numeral 9 is provided in front of this blower 16 and connected to the pillars 2 to 9.
5, the front panel is fixed to the front left and right columns 2.3 with screws 6.

In such a heat exchanger mounting structure, the motor 17
When the fan 18 is rotated by the drive of the fan 18 , the air sucked in from the suction port (not shown) passes through the heat exchangers 8 and 9 and is blown out from the air outlet (not shown) of the air path duct 13 . At this time, the refrigerant flowing inside the tube body 11 of the heat exchanger 8.9 exchanges heat with the suction air.

[Problem to be solved by the invention]

By the way, the conventional heat exchanger mounting structure does not have a holding function for attaching the heat exchangers 8.9 to the base plate 1, and therefore each heat exchanger 8.9 is suspended in the air. There was a problem in that it had to be installed, making the installation work complicated.

In addition, five columns 2 to 5 are required for mounting each heat exchanger 8.9.
．． 7, which increases the number of parts and increases costs.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a heat exchanger mounting structure that can simplify the mounting work and reduce assembly costs.

[Means to solve the problem]

The heat exchanger mounting structure according to the present invention is a structure in which a heat exchanger having a tube for heat exchange is mounted on a base plate, and a holding piece for holding the tube is formed by cutting and bending plywood. It was established.

[For production]

In the present invention, the heat exchanger can be attached to the plywood with the heat exchange tube held on the holding piece.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the structure etc. of this invention will be explained in detail by the Example shown in the figure.

1, 2, and 3 are front views, top views, and back views showing the mounting structure of a heat exchanger according to the present invention, and FIG. 4 is an enlarged view of the main part of the heat exchanger mounting structure. FIG. 5 is a perspective view showing plywood used in the mounting structure of the heat exchanger.
FIG. 6 is a perspective view showing the outdoor unit, and in this figure, the same members as in FIGS. 7 to 10 are denoted by the same reference numerals, and detailed explanations are omitted. In the figure, a total of six holding pieces 22 for holding the tubular body 11 are integrally erected at the front, rear, left, right, and rear center of the plywood indicated by the reference numeral 21 by cutting and bending them into a rectangular shape. These holding pieces 22 are positioned between the two adjacent fins 10, and have a semicircular notch A formed in the upper part of the holding surface 22 to fit the outer peripheral surface 11a of the tube body 11.
3 is provided.

In such a heat exchanger mounting structure, the holding piece 22
The heat exchanger 8 is placed against the base plate 21 while holding the tube body 11 at
．． 9 can be attached. That is, at the time of attachment, the outer circumferential surface 11a of the tubular body 11 is placed on the holding surface 23 of the holding piece 22.

Further, in the present invention, since the columns 2 to 5 and 7 extending in the vertical direction are not required for mounting the heat exchangers 8 and 9,
The suction resistance can be reduced accordingly, and the heat exchange rate can be reliably increased.

Further, the base plate 21 of the present invention is provided with holes B by cutting and raising the holding pieces 22, thereby improving drainage performance during rain.

Incidentally, in the present invention, the heat exchanger 8
. Of course, it can be applied to other devices.

Further, the shape and number of the holding pieces 22 in the present invention are not limited to the above-mentioned embodiments, and may be, for example, eight holding pieces cut and raised into a trapezoidal shape, and the shape and number of two pieces may be modified or changed as appropriate. That is freedom.

〔Effect of the invention〕

As explained above, according to the present invention, there is a structure in which a heat exchanger having a tube body for heat exchange is mounted on a base plate, and a holding piece for holding the tube body is provided by cutting and bending plywood. Therefore, the heat exchanger can be attached with the tube held by the holding piece, and the heat exchanger attachment work can be simplified. Furthermore, since the supports that were conventionally required for mounting the heat exchanger are no longer necessary, the number of parts can be reduced, and assembly costs can also be reduced.
