Description

Compact compressor noise protection and cooling unit

The present invention relates to a noise preventing and cooling device of a small compressor, and more particularly, to effectively cool the heat generated by the compressor while preventing noise generated from the compressor so that the small compressor can be used indoors. Relates to compressor noise protection and a cooling device.

Generally, a compressor is a mechanical device that compresses gas to increase pressure, and is also called a compressor. It is used for various kinds of functions and control indoors in modern factories, small labs, learning rooms, hospitals, etc.

Compressors are basically the same as pumps in that they compress the fluid and apply mechanical energy to the fluid, but pumps compress liquids and are distinguished from pumps in that pressure is applied to the gas to convert pressure and speed.

Compressors are widely used in various fields. In particular, compact compressors of about 0.5 to 2 hp are used to operate various devices in hospitals, small laboratories, learning rooms, and pneumatic control devices.

Such compact compressors are difficult to use indoors unless they are overcome by noise, vibration and heat generation. For this reason, the compressor is not installed indoors but is installed outdoors to operate the compressor through a remote control from a long distance. Inevitably, when used indoors, there was no choice but to accept pollution due to noise.

Therefore, in order to use a compact compressor indoors, an apparatus capable of preventing noise, vibration, and heat generated from the compressor is required. This is very urgent, for example, the higher the quality of life a person needs, the better the environment in the workplace, treatment room, or workplace. The noise causes tremendous stress on the real user. Therefore, there is a need for the development of a compressor device that can improve the quality of life for workers and users who use the compressor and provide a pleasant environment in the workplace and workplace.

The present invention has been made to solve the above problems, the present invention provides a compressor noise prevention and cooling device that can cool the heat generated in the compressor at the same time to reduce the noise and vibration generated primarily in the compressor. It is.

In order to use a compact compressor indoors, it is necessary to dramatically reduce vibration and noise generated from the compressor. The present inventors have devised a method of manufacturing a rectangular parallelepiped protective box in order to reduce the vibration and noise generated in the compressor, and inserting the compressor therein to seal it.

The present inventors attached a sound absorbing material in the form of styrofoam or sponge to the inner surface of the protective box in order to remove noise generated by the compressor, and in order to prevent vibration generated by the compressor, a plurality of springs are installed on the inner surface of the protective box. The compressor was configured to float in the air without touching the protective box.

As a result, the noise and vibration generated in the compressor could be prevented, but a new problem occurred. That is, when the compressor is sealed in the protection box of the hexahedron, there is a problem that the temperature in the protection box continues to increase due to the heat generated by the compressor.

In order to solve this problem, the present inventors adopted a water-cooled cooling method. Cooling water (water) flows along the cooling water pipe, and the cooling water pipe is configured to surround the compressor. In addition, a cooling tank containing coolant is attached to the cylinder head part that generates the most heat in the compressor to maximize cooling efficiency.

In accordance with a preferred embodiment of the present invention, a compressor noise preventing and cooling device for cooling the heat and preventing noise generated in a compact compressor is

Compressor main body 10; A protective box 20 surrounding and protecting the compressor body and preventing noise generated from the compressor; A cooling water pipe (30) which directly surrounds a cylinder head, a cylinder outer wall, or a core outer wall of a motor, in a coil shape, in which the heat is most generated in the compressor so as to effectively cool the heat generated by the compressor; A cooling water storage tank 40 connected to the cooling water pipe and storing the cooling water; A driving pump circulating the cooling water so as to flow along the cooling water pipe; And a plurality of springs 70 connected to the compressor body and the protection box so that the compressor body floats in the air so as not to come into contact with the protection box to absorb vibrations generated by the compressor body.

Preferably, the apparatus further includes a cooler 80 connected to the cooling water pipe to cool the cooling water flowing along the cooling water pipe.

Preferably, it comprises a cooling tank 60 connected to the cooling water pipe and attached to the side of the cylinder head of the compressor body to cool the heat generated in the cylinder head of the compressor body.

Preferably, the sound absorbing material 22 for reducing the noise of the compressor main body is attached to the inner surface of the protective box.

Compressor noise prevention and cooling device of the present invention can reduce the noise by sealing the compressor body in the protective box, it is possible to prevent the noise more efficiently by installing a sound absorbing material on the inner surface of the protective box.

In addition, there is an advantage that the vibration of the compressor can be caught efficiently and inexpensively by supporting the compressor main body in the center inside the protective box using a spring.

In addition, there is an advantage that the heat generated in the compressor body can be efficiently cooled by the water-cooled cooling device.

Hereinafter, with reference to the accompanying drawings will be described in more detail the compressor noise prevention and cooling device of the present invention.

* Referring to Figure 1, the compressor noise prevention and cooling device of the present invention, the compressor main body 10, the protection box 20 for sealing the compressor main body, the coolant pipe 30 through which the coolant flows, the coolant storage tank in which the coolant is stored ( 40, a drive pump 50 for circulating the coolant, a cooling tank 60 for cooling the cylinder head of the compressor, a plurality of springs 70 for reducing the vibration of the compressor body, a cooler 80 for cooling the coolant It includes.

The compressor main body 10 is a compact compressor that can be used indoors, and is an air-cooled compressor of about 1 horsepower. However, it is of course not limited to this.

The protection box 20 in which the compressor main body 10 is built is a substantially hexahedral shape and will be referred to as a housing protecting the compressor main body. The compressor body 10 is sealed in the protective box 20. The protective box 20 is preferably made of metal or wood in order to protect the external impact.

The sound absorbing material 22 is attached to the inner surface of the protective box 20 to more effectively reduce the noise of the compressor main body 10. Preferably, the sound absorbing material 20 is a material for sound insulation and sound absorption.

The spring 70 supports the compressor body from all sides floating in the air. The number of springs 70 is not necessarily limited thereto, but four are provided on the upper side and four on the lower side. By the spring 70, the compressor main body 10 is suspended in the air without contacting the protective box 20, thereby effectively reducing the vibration generated in the compressor main body 10. This is because the vibration of the compressor main body 10 is absorbed by the elastic force of the spring 70.

Cooling water (water) flows into the cooling water pipe 30 surrounding the compressor main body 10. The cooling water pipe 30 wraps the compressor main body 10 in a coil shape as shown in order to cool the heat generated in the compressor main body. Preferably, the cooling water pipe 30 is made of copper having ductility and high thermal conductivity.

The cooling water pipe can further increase the cooling efficiency by allowing the cooling water to flow around a portion of the compressor main body, that is, the cylinder head, the cylinder outer wall, or the core outer wall of the motor.

Cooling water flowing along the cooling water pipe 30 is circulated by the drive pump 50 and stored in the cooling water reservoir 40. When the coolant is to be replenished from the outside, the coolant is poured into the coolant reservoir to replenish the coolant. The drive pump 50 uses a small pump with low noise.

The cooler 80 is a device for cooling the cooling water flowing along the cooling water pipe 30. When the coolant absorbs the heat of the compressor, the temperature rises, and the cooler 80 is installed to cool the coolant having the elevated temperature.

A cooling tank 60 for cooling the cylinder head is attached to the side of the cylinder head that generates the most heat among the compressor bodies. The cooling tank 60 is also connected to the cooling water pipe 30 to flow the cooling water therein. The reason for separately forming the cooling tank is to more effectively cool the cylinder head portion that generates the most heat. The cooling tank 60 may be preferably made of aluminum or copper, it is possible to maximize the cooling efficiency by forming a plurality of partitions in the cooling tank 60 to increase the area in contact with the cooling water.

2 is a schematic perspective view showing a compressor body and a cooling tank of a compressor noise suppression and cooling device according to a preferred embodiment of the present invention.

2, the compressor main body 10 is a conventional compact compressor. On the upper side of the compressor main body 10, a cylinder head 12 is formed which covers and protects the reciprocating cylinder. The cylinder is the part that generates the most heat of the compressor with continuous up and down reciprocation. In order to cool the heat generated in the cylinder, a cooling tank 60 is installed on the side of the cylinder head. Although not shown in the figure, the cooling tank 60 is connected to the cooling water pipe and the cooling water flows inside. In the drawing, the shape of the cooling tank 60 is not limited to the shape of the rectangular parallelepiped, but is not necessarily limited thereto, as long as the cooling tank 60 is installed on the side of the cylinder head to effectively cool the heat of the cylinder head.

In FIG. 3, a cooling tank 60 is attached to both sides of the cylinder head 12 of the compressor body 10 to cool the heat generated in the cylinder head 12.

실시예EXAMPLE

A compressor was purchased to configure the compressor noise protection and cooling device as shown in FIG.

First, a noise measuring device was installed on the side of the compressor while the compressor was not placed in a protective box, and the noise of the compressor was measured during operation of the compressor. The measurement was about 70 dB.

Then, after putting the compressor in a protective box, the noise was measured during operation of the compressor outside the protective box using a noise measuring device in a completely closed state. The measurement was about 40 dB. When sealed with a protective box, the noise was reduced by about 30dB.

On the other hand, after the compressor is completely enclosed in a protective box, the driving motor is not driven and the cooling water does not flow, and the compressor is driven for 1 hour, and then the temperature inside the protective box is measured using a thermometer. The measured value was about 90 degreeC.

Then, after opening and closing the protective box, the drive motor was driven to completely cool the compressor.

After the compressor was completely sealed again, the drive motor was driven, and the compressor was again driven for 1 hour, and then the temperature inside the protective box was measured using a thermometer. The measurement was about 30 ° C.

Of course, the results of the experiment may be slightly different depending on summer and winter or room temperature.

Through the above experiments, it was confirmed that the compressor noise prevention and cooling device of the present invention can effectively prevent noise and simultaneously cool heat.
