Abstract

PURPOSE:To reduce a vibration of a heat exchanger, and to prevent generation of noise due to the vibration and damage of a mounting mechanism by improving mounting intensity and rigidity of a fin and tube type heat exchanger. CONSTITUTION:An arbitrary number of fixing brackets 21 are inserted fixedly at an interval between side plates 93 of both ends of a fin and tube type heat exchanger 9, and fixed to a base plate 1d.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor unit for an air conditioner.

[0002]

2. Description of the Related Art An example of an outdoor unit of a conventional separation type air conditioner is shown in FIG. The inside of the device casing 1 of the outdoor unit is partitioned into a left side and a right side by a partition plate 2, and a machine room 3 is formed on one side and a heat exchange chamber 4 is formed on the other side.

A compressor 5 and the like are arranged in the machine room 3. An L-shaped fin-and-tube heat exchanger 9, a propeller fan 10, and a motor 14 are arranged in the heat exchange chamber 4.

The L-shaped heat exchanger 9 is opposed to an air intake 11 formed on the back surface 1a of the housing 1 and an air intake 12 formed on the left side surface 1b. Further, the propeller fan 10 is arranged so as to face the air outlet 13 formed on the front surface 1c of the device casing 1.

As shown in FIG. 2 (D), the fin-and-tube heat exchanger 9 includes a large number of fins 91 standing upright with a small gap and a tube 92 extending horizontally through the fins 91. The bracket 17 is fixedly installed on the base plate 1d of the device casing 1 by fastening the brackets 17 fixed to the lower ends of the side plates 93 arranged on both the left and right ends of the fin 91 to the base plate 1d with the screws 18.

When the propeller fan 10 is rotationally driven by the motor 14, the outside air flows from the air intake ports 11 and 12 into the heat exchange chamber 4.
The temperature is increased or decreased by heat exchange with the refrigerant flowing in the tube 92 in the process of being sucked into the fin and tube type heat exchanger 9 and flowing through the gap of the fins 91 of the fin-and-tube heat exchanger 9, and then urged by the propeller fan 10. And is discharged to the outside from the outlet 13.

[0007]

In the conventional outdoor unit described above, since the fin-and-tube heat exchanger 9 is fixedly installed on the base plate 1d via the side plates 93 at both ends thereof, its mounting strength and The rigidity is low, and therefore, when the compressor 5 vibrates, the heat exchanger 9 also vibrates and generates noise, and in extreme cases, there is a risk that the mounting mechanism will be damaged.

SUMMARY OF THE INVENTION The present invention has been invented to solve the above problems, and its gist is to provide a fin-and-tube heat exchanger having side plates at both ends in a casing. In an outdoor unit of an air conditioner fixedly installed on a base plate via the side plates, an arbitrary number of sheets arranged below the fin-and-tube heat exchanger with a space between the both side plates. In the outdoor unit of the air conditioner, the fixing brackets are inserted and fixed, and the fixing brackets are fixed to the base plate.

From the bracket having an L-shaped cross section, the fixing bracket includes a portion having a hole through which a tube of the fin-and-tube heat exchanger is inserted and inserted between the fins and a portion fixed to the base plate. Can be configured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention is shown in FIG. Side plates arranged at both ends of the fin-and-tube heat exchanger 9
An arbitrary number of fixing brackets 21 are inserted and fixed in the lower gaps of the fins 91 at intervals with respect to each other.

Each fixing bracket 21 has a hole 24 through which a tube 92 penetrates, and a portion 21a inserted into the gap of the fin 91.
And an L-shaped cross section consisting of a portion 21b fixed to the base plate 1d. It is desirable that the lower three tubes 92 be expanded and fixed to the fixing bracket 21.

Then, the screw 22 penetrates through the bolt hole 25 formed in the rising edge of the peripheral edge of the base plate 1d, and is screwed into the bolt hole 23 formed in the portion 21b of the fixing bracket 21 for fastening. As a result, the fixing bracket 21 is fixed to the base plate 1d. The side plate 93 is a bracket like the conventional one.
It is fixed to the base plate 1d via 17.

[0013]

According to the present invention, the fin-and-tube heat exchanger is fixed to the base plate through the side plates at both ends thereof and the arbitrary number of fixing brackets inserted and fixed at intervals between them. Therefore, the mounting strength and rigidity are significantly improved as compared with the conventional one. Therefore, since the vibration of the fin-and-tube heat exchanger can be reduced, it is possible to prevent the generation of noise due to the vibration and the damage of the mounting mechanism.
