Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air compressors, and in particular to a liquid-cooled scroll air compressor. Background Art
[0002] A scroll compressor is a positive displacement compressor. Its compression components mainly include a moving scroll and a static scroll. When the air enters the air intake, the space is continuously reduced through the scroll structure, thereby achieving the purpose of compressing the gas. Scroll air compressors are now widely used in industrial applications, medical equipment, the automotive industry, and energy and environmental places that need to provide clean gas and cooling due to their low noise, high energy efficiency, less vibration, and less maintenance. When the scroll compressor is working, a large amount of heat is generated. There are two main methods for dissipating the heat of the scroll compressor: one is to install a fan on the side of the compressor and rely on the wind to dissipate the heat from the static scroll; the other is to install a wind wheel on the drive shaft to blow air, and then add a flow channel to guide the wind to the heat dissipation ribs of the moving and static disks for cooling.
[0003] In the prior art, scroll compressors mainly rely on air cooling systems for heat dissipation. First, the heat dissipation effect of the air cooling system is greatly affected by the ambient temperature. When the ambient temperature is high, the heat dissipation effect of the air cooling system will be significantly reduced, which will lead to a decrease in the operating efficiency of the compressor and even affect the reliability and service life of the equipment. In addition, the air cooling system requires sufficient space to ensure air circulation. If the installation location is poorly ventilated, it will affect the heat dissipation effect and overall performance of the compressor. Secondly, the scroll compressor of the air cooling system relies on fans for heat dissipation, which will generate a lot of noise during operation, affecting daily work and life, and in order to achieve a better heat dissipation effect, it is usually necessary to increase the fan or increase the fan power, which will increase energy consumption and increase the power of the compressor; finally, because the air cooling system requires air circulation when working, the scroll compressor cannot be completely sealed, which reduces the application scenarios of the compressor. Summary of the invention
[0004] The present invention aims to provide a liquid-cooled scroll air compressor to solve the deficiencies in the prior art. The technical problem to be solved by the present invention is achieved through the following technical solutions.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0036] Example 1
[0037] like Figure 1 As shown, a liquid-cooled scroll air compressor includes a stator plate 2, a movable plate 3, a frame 8 and a motor seat 10, a cover plate 1 is arranged on the outer side of the stator plate 2, a first coolant flow channel is arranged between the cover plate 1 and the stator plate 2, the first coolant flow channel is arranged on the stator plate 2, a movable plate seat 5 is arranged between the movable plate 3 and the motor seat 10, a second coolant flow channel is arranged between the movable plate seat 5 and the movable plate 3, the second coolant flow channel is arranged on the movable plate 3, and the second coolant flow channel is connected to the second liquid inlet 11 and the second liquid outlet 12 on the motor seat 5 through a small crank 6 with holes and a screw 7 with holes on the movable plate seat 5.
[0038] In order to ensure that the coolant does not overflow as the compressor works, the stator 2 and the frame 8 are sealed by a first sealing ring 4, and the frame 8 and the motor base 10 are sealed by a second sealing ring 9. In addition, when installing the motor, the sealing gasket on the motor end face is used to achieve the sealing of the entire machine.
[0039] like Figure 2As shown, it shows the specific structure of the static plate flow channel. The cover plate 1 is provided with a first liquid inlet 13 and a first liquid outlet 14, and the first liquid inlet 13 and the first liquid outlet 14 are connected to the first coolant flow channel on the static plate 2. The first liquid inlet 13 is arranged at the edge of the static plate 2 and connected to the first coolant flow channel. The two first liquid outlets 14 are arranged at the center of the static plate 2 in a symmetrical structure. The first coolant flow channel is divided into two symmetrical parts, which are annular as a whole, and the two parts are partially connected. Combined Figure 2 As shown, after the coolant enters the first coolant flow channel from the first liquid inlet 13, it flows along the annular coolant flow channel and is finally discharged from the two first liquid outlets 14 on both sides of the center. The coolant flow channel is arranged in an annular shape to take away the heat generated at various parts of the impeller, achieving a uniform heat dissipation effect.
[0040] like Figure 3 As shown, the static plate 2 includes a first liquid inlet 13 and two first liquid outlets 14 .
[0041] In order to enhance the overall sealing, a silicone sealing ring is also provided between the static plate 2 and the cover plate 1, and a third sealing ring is also provided between the dynamic plate 3 and the dynamic plate seat 5.
[0042] like Figure 1 and Figure 4 As shown, the moving disk 3 includes two second liquid inlets 11 and a second liquid outlet 12. The two second liquid inlets are respectively arranged on opposite sides of the moving disk and connected to the second coolant flow channel. The second liquid outlet is arranged at the center of the moving disk. The second coolant flow channel is divided into two symmetrical parts, which are annular as a whole and partially connected to each other. Figure 4 As shown, after the coolant enters the second coolant flow channel through the two second liquid inlets 11, it flows along the annular coolant flow channel and is finally discharged from the second liquid outlet 12 at the center. Although the second coolant flow channel on the moving disk 3 is not exactly the same as the first coolant flow channel on the static disk 2 in structure, the overall structure is similar. The coolant flow channels are both annular and connected in the middle. This arrangement can take away the heat generated in various parts of the moving disk and achieve the effect of uniform heat dissipation.
[0043] The coolant can be selected according to the temperature of different regions, such as water, oil, refrigerant, etc. For example, water can be used as the coolant in the warm southern region, and refrigerant can be used as the coolant in the cold northern region. This is a well-known technical means in the art and will not be elaborated here.
[0044] like Figure 6-7 As shown, the small crank 6 is hollow. Figure 7 , c is an oblique hole connected to a and b. The holes connecting the moving plate, the small crank with holes, the screws with holes, the moving plate seat, the frame and the motor seat constitute the second coolant flow channel. The flow channel direction is as follows Figure 6 As shown, the moving disc seat 5 and Figure 7 Part a in the middle makes a circular motion together, and the moving plate seat 5 and Figure 7 The middle part a is relatively static, so a sealing ring can be used for static sealing. The frame 8 is static and the motor seat 10 is static. Figure 7 When middle b makes a rotational motion, the frame 8 and the motor seat 10 can be statically sealed using a sealing ring. At the same time, the small crank is hollow so that the circulation of the second flow channel can be guaranteed.
