Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a water cooling structure of an oil-free scroll compressor. Background Art

[0002] Scroll compressors have the characteristics of high speed, low energy consumption, long service life, and simple maintenance. They are a technology that has developed rapidly in recent years, especially scroll oil-free compressors. At present, all of them use forced air cooling to achieve cooling and temperature reduction, which has certain requirements for the use environment. For the air-cooled oil-free scroll compressor structure in the prior art, most of them use a centrifugal fan installed at the end of the main shaft of the oil-free scroll compressor. When the scroll compressor enters the working state, the main shaft drives the centrifugal fan to rotate, and the wind discharged by the centrifugal fan cools the back of the dynamic and static scroll disks of the scroll compressor through the air guide channel. This structure can cool the dynamic and static scroll disks of the compressor very well, and is also widely used in current production and manufacturing.

[0003] However, this structure also has some disadvantages: first, when the outside temperature is high, the indoor air temperature is relatively high, and the temperature of the gas discharged by the centrifugal fan is also high, and the cooling effect is not good at this time; after the gas discharged by the centrifugal fan passes through the heat sink of the dynamic and static scroll disks, the gas stays in the heat sink for a short time and is not easy to cool. And because the speed of the centrifugal fan is constant, the temperature will gradually increase after the heat exchange with the dynamic and static scroll disks. When the main shaft rotates at high speed for a long time, the wind generated by the rotation of the centrifugal fan can no longer cool the scroll disk well. Utility Model Content

[0026] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

The water inlet box 2 is arranged on one side of the static vortex 1, and the water outlet box 4 is arranged on the other side of the static vortex 1. A plurality of the water cooling channels 3 are arranged on the static vortex 1. A plurality of the water cooling channels 3 are connected with the water inlet box 2 and the water outlet box 4 so that water can flow along the water inlet box 2 along any of the water cooling channels 3 to the water outlet box 4. The water retaining groove 5 is arranged on the static vortex 1 and is arranged around the outer periphery of the water inlet box 2, the plurality of the water cooling channels 3 and the water outlet box 4. The water retaining plate 6 is covered on the water retaining groove 5. One end of the sealing member is embedded in the water retaining groove 5, and the other end of the sealing member is connected to the water retaining plate 6.

[0028] Specifically, a water inlet box 2, a water outlet box 4 and a water cooling channel 3 are arranged on the back of the stationary scroll 1, that is, the side facing away from the movable scroll. This part of water enters the water inlet box 2 from the outside, and is diverted into several water cooling channels 3 through the water inlet box 2. The compression chamber is cooled by heat exchange in the water cooling channel 3, and the high-temperature water after cooling enters the water outlet box 4. The high-temperature water in the water outlet box 4 is connected to the outside through the water outlet on the water baffle 6. The number of water cooling channels 3 is multiple, and it can also be one or two as needed, which is not limited here. The water flowing out through the water outlet can be cooled by an external cooling device and then enter the water inlet box 2 again through the water inlet, so as to cool the oil-free scroll compressor in a cycle. Such a design can well meet the purpose of heat dissipation of the oil-free scroll compressor. On the premise of meeting the performance requirements of the oil-free scroll compressor, the exhaust temperature is lower, the deformation of the scroll disk is smaller, and the scroll compressor operates well. The overall shape of the water retaining groove 5 is a square, and its length and width are both smaller than the length and width of the static vortex 1. With this arrangement, the sealing ring can also be in a square shape as a whole, or in four long strips, so that the sealing ring can be more stably and flexibly embedded in the water retaining groove 5, thereby achieving sealing to ensure the water cooling effect. The water retaining plate 6 can be a square plate, and the outer circumference of the water retaining plate 6 is not less than the outer circumference of the water retaining groove 5, so that the water retaining plate 6 can cover the water inlet box 2, the water outlet box 4 and the water cooling channel 3 at the same time.

[0030] Specifically, a sealing groove 7 is provided on the water retaining plate 6, and the sealing groove 7 is arranged opposite to the water retaining groove 5. A sealing member is used to connect the sealing groove 7 and the water retaining groove 5, so that the sealing effect between the water retaining plate 6 and the sealing groove 7 is good, so that the sealing effect of the water cooling structure is good, thereby the heat dissipation effect is good.

[0031] In this embodiment, the sealing member is made of rubber material, has good sealing effect, is easy to replace and has low cost.

[0032] In this embodiment, the water baffle plate 6 is connected to the water inlet box 2 by threads; and / or the water baffle plate 6 is connected to the water outlet box 4 by threads. The threaded connection is reliable and easy to replace.

[0033] In this embodiment, the shapes of the plurality of water cooling channels 3 are all curved, so that water can flow on the water cooling channels 3 for a longer time, thereby enhancing the cooling effect. In an alternative embodiment, the water cooling channels 3 are linear, with their inlets facing the water inlet tank 2 and their outlets facing the water outlet tank 4.

[0034] In this embodiment, the two sides of the water cooling channel 3 are symmetrically arranged on the static vortex disk 1, so that the heat dissipation on the left and right sides is uniform and the effect is good.

[0035] In this embodiment, the water cooling channels 3 are evenly spaced on the static scroll 1 to ensure uniform heat dissipation up and down and left and right.

[0036] The distribution and style of the water cooling channel 3 can be varied. The distribution can be uniform, or it can be dense at the top and dispersed at the bottom according to the water flow. The style can be a straight water cooling channel 3 or a curved water cooling channel 3. In this embodiment, the water cooling channel 3 is symmetrical and evenly distributed in curved lines.

[0037] In this embodiment, a water inlet and a water outlet are provided on the water baffle plate 6 , the water inlet is communicated with the water inlet box 2 , and the water outlet is communicated with the water outlet box 4 .

[0038] Specifically, the water inlet is arranged on the side of the baffle plate close to the water inlet tank 2, and the water outlet is arranged on the side of the baffle plate close to the water outlet tank 4. The water baffle plate 6 provides a setting space for the water inlet and the water outlet, and makes the design of the water inlet and the water outlet simple, and makes the overall structure of the water cooling structure firm, so that the water cooling is stable and the water cooling effect is better.
