Description

[Detailed Description of the Invention] This invention relates to a cooling device for a so-called packaged compressor, in which the compressor is housed in a soundproof casing.

For packaged compressors, we make effective use of the space in the housing to create air pockets to make the entire machine more compact, and we also increase the surface area of the air pockets to ensure good cooling performance through forced cooling air. It is being done to

However, in conventional package compressors, the air intake port of the cooling air supply mechanism is provided in only one place, so the cold air is distributed evenly to the entire air pocket that is distributed or all at once inside the tube. There was a defect that the cooling efficiency was extremely low because it could not be spread across the air.

Therefore, the present invention was carried out with the aim of eliminating such defects in the actual situation, and its gist is that in a structure in which an air pocket is formed by arranging an appropriate pipe body in communication within the soundproof casing of a packaged compressor, The casing is separated into a main storage chamber and an auxiliary chamber, and the compressor is housed in the main storage chamber. In addition, tube materials are also installed vertically at the four corners of the main storage chamber in a plan view, and these are interconnected by communicating pipes. In addition to communicating with each other to form an air pocket, the auxiliary chamber is further divided into two cooling air supply passages on both sides and one ventilation passage in the center, and these supply passages and ventilation passages are located adjacent to the main storage chamber. A cold air intake port and a communication port are formed between the two supply channels and the outside air side and the main storage chamber, respectively.

An exhaust communication port and an exhaust port are respectively formed between the main storage chamber and the outside air side with respect to the exhaust passage, and the low-temperature outside air sucked in from the two cold air intake ports is introduced into the air pocket of the main storage chamber. It is characterized by being configured so that it is forcibly supplied.

This will be explained below with reference to drawings of specific examples. A is a packaged compressor, and its soundproof casing 1 is formed by attaching a soundproof wall material 2 such as a steel plate to the frame, or in some cases, it is formed by attaching a soundproof wall material 2 such as a steel plate to the frame. It has a double structure or has a sound-absorbing material attached to the inner surface, and consists of a main storage chamber 3 and a sub-chamber 4.
A main compressor is installed in the main storage chamber 3.

Although illustration of this compressor is omitted, as is well known, it consists of a power source and an air compression supply section, and the discharge port of the air compression supply section is connected to the air reservoir 5.

As shown in the drawing, the air pockets 5 are located in the four corners of the main storage chamber 3, which is the space formed between the part where the compressor is housed and installed and the outer peripheral soundproof wall, in the vertical direction in the four corners of the plan view. It is formed by distributing and erecting tube materials 6 and communicating them through a communication tube 7.

In addition, the sub-chamber 4 installed on the side of the main storage chamber 3 has cold air intake ports 10.11 on the left and right side walls 8 and 9, respectively. Partition wall 12 within 4.
Cooling air supply channels 14 at two locations on both the left and right sides formed by 13.
Connect to 15.

An air exhaust passage 19 is formed at one location in the center of the subchamber 4 by the partition walls 12 and 13.

Therefore, each of the supply passages 14, 15 and the exhaust passage 19 is arranged adjacent to the main storage chamber 3.

The cooling air supply passage 14.15 is connected to the main storage chamber 3 at the upper part through a communication passage 16.17'! z, and the exhaust passage 19 is provided with an exhaust communication port 18 which is buttoned at the lower part and communicates with the main storage chamber 3, and a suction fan device 20 is provided in the exhaust passage 19 portion corresponding to the opening 18, An exhaust port 21 is provided at the upper end of the air exhaust passage 19.

In a package compressor with such a configuration, when the main compressor in the storage chamber 3 is operated, air is compressed and sent from its discharge port to the air reservoir 5.
Compressed air can be supplied from the discharge pipe to the air circuit outside the machine when necessary.

During this operation, the suction fan device 20 of the exhaust passage 19 of the sub-chamber 4 operates at the same time, thereby sucking in air from the main storage chamber 3 through the exhaust communication port 18 and exhausting it from the upper exhaust port 21. Therefore, along with this, the cooling air intake ports 10 on both sides.
11, low temperature outside air is sucked in, and the supply path 14.15'
After that, it is introduced into the main storage chamber 3 through the communication ports 16 and 17,
The air flows around the tubes constituting the air pockets 5 arranged in a dispersed manner, and reaches the exhaust communication port 18 as described above while cooling them.

This continues the cooling process in which the air is discharged to the exhaust air passage 19 in the subchamber.

As is clear from the above description, according to this invention, low-temperature outside air is forcibly sucked in by the suction fan device 20 through the cold air intake ports 10 and 11 formed at two locations, increasing the surface area of the installed air pocket. Since the air is discharged from the exhaust port 21 after evenly contacting the entire housing, the cooling efficiency is significantly improved compared to a configuration in which air supplied from one intake port is circulated throughout the housing for cooling.

In addition, since a large amount of low-temperature outside air can be constantly supplied from two intake ports, sufficient cooling can be ensured without unnecessarily increasing the flow rate of forced intake and exhaust, and this also has the effect of preventing noise caused by the operation of this device. It can be done well.
