Detailed Description

The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

With reference to fig. 1 to 6, an integrated air cooling device includes a device body 100, an air purification structure and an air cooling and heating separation structure are provided in the device body 100, wherein the air cooling and heating separation structure includes a vortex guiding chamber 10, one end of the vortex guiding chamber 10 is communicated with a closed vortex forming tube 20, and the other end thereof is provided with a cold air discharge port 11; a cold air guide pipe 50 communicated with the vortex forming pipe 20 is further arranged in the vortex guide chamber 10, one end of the cold air guide pipe 50 is matched with the cold air outlet 11 to output cold air out of the device body 100, a vortex guide ring 51 is arranged between the other end of the cold air guide pipe 50 and one end of the vortex forming pipe 20, and the vortex guide ring 51 enables compressed air to enter the vortex forming pipe 20 in a direction internally tangent to the inner wall of the vortex forming pipe 20; the part of the vortex forming pipe 20 far away from the vortex guiding cavity 10 is provided with a hot gas outlet 21; the air purification structure comprises a closed air inlet pipeline 30, one end of the air inlet pipeline 30 is provided with an air inlet communicating part 40 communicated with the wall part of the vortex guide cavity 10, the air inlet pipeline 30 is further provided with a compressed air inlet 31, and a filtering structure for purifying air is arranged between the air inlet communicating part 40 and the compressed air inlet 31 in the air inlet pipeline 30; an oil-water outlet 32 is formed at one end of the air inlet pipeline 30, which is far away from the filtering structure.

The design integrates air purification treatment and refrigeration, avoids the problems that the parts are damaged easily due to excessive parts and excessively complex devices, so that air leakage or poor refrigeration effect is caused, improves the refrigeration effect, reduces the volume of the device and lightens the burden of a user. The intake communicating portion 40 is a component that communicates the intake duct 30 and the vortex guiding chamber 10, and when the intake duct 30 directly contacts with the outer wall of the vortex guiding chamber 10, the intake communicating portion 40 may be a through hole directly formed on the intake duct 30 and the vortex guiding chamber 10; when the outer walls of the two are not in direct contact, the two can be respectively provided with the through holes, and the connecting pipe is additionally arranged to communicate the two through holes.

The vortex guide ring 51 is used to change the flow direction of the compressed gas to make it enter tangentially relative to the inner wall of the vortex forming tube 20, so that the compressed gas entering the vortex forming tube 20 spirally moves along the inner wall of the vortex forming tube 20 toward the hot gas outlet 21, and then a part of the compressed gas is discharged from the hot gas outlet 21 and a part of the compressed gas flows back along the axis of the vortex forming tube 20 toward the cold gas outlet 11. During the operation of the compressed gas against the vortex forming tube 20, the temperature of the compressed gas rises due to friction with the inner wall, and the gas flowing back in the axial direction is continuously heat-exchanged with it, so that the temperature of the flowing back gas is continuously lowered.

Specifically, as shown in fig. 5 and fig. 6, the vortex guide ring 51 includes a plurality of wedge-shaped guide blades 511 arranged in a ring shape, and a gap for air to enter is left between two adjacent guide blades 511; the plane of the inner sides of the guide vanes 511 is substantially tangential to the circumferential direction of the inner wall of the vortex forming tube 20. The flow direction of the compressed gas is changed by arranging the guide fan blades 511, the speed of air vortex is increased, and the air cooling efficiency is further improved.

Regarding the filtering structure, the compressed gas is purified before the compressed gas vortex refrigeration, so that oil and water carried by the gas are prevented from fouling the refrigeration structure. There are several ways to achieve the purification of the compressed gas.

As shown in fig. 1, the air intake communication portion 40 and the compressed air intake port 31 may be provided with a filter mesh sheet 61, the filter mesh sheet 61 is located between the air intake communication portion 40 and the compressed air intake port 31, and a side edge of the filter mesh sheet 61 is circumferentially attached to an inner wall of the air intake duct 30 without a gap, so that the compressed air is prevented from avoiding the filter mesh sheet 61 from contacting the inner wall of the air intake duct 30.

As shown in fig. 2, it is also possible to realize this by providing an annular filter 62, a side wall of the annular filter 62 can be attached to the intake communicating portion 40, and compressed air passes through the annular filter 62 and enters the intake communicating portion 40 through a side wall filter hole thereof.

It should be noted that, no matter the rib 721 is disposed on the inner wall or the outer wall of the oil-water guide ring 72, the compressed air must not be prevented from entering the air inlet duct 30 through the filter mesh sheet 61 or the filter net. Further, when the rib 721 is provided on the inner wall, the oil-water guide ring 72 is inevitably a hollow ring-shaped body or a cylindrical body. However, when only the rib 721 is provided on the outer wall, the oil-water guide ring 72 does not necessarily need to be hollow, and in other words, may be a solid cylindrical body.

In the rib 721, in order to increase the oil-water adhesion area and further improve the oil-water discharge guiding efficiency, the rib 721 may be formed as a continuous thread from one end of the oil-water guiding ring 72 to the other end. Thus, the length of the convex edge is extended, and the length of the oil and water which can be supplied is increased.

As shown in fig. 4, the oil and water guiding structure may be a female screw-shaped protrusion 73 provided on the inner wall of the intake duct 30, and the protrusion 73 may extend in a screw shape toward the oil and water outlet 32 on the inner wall of the intake duct 30. The design is not additionally provided with an independent structure, and an oil-water guide structure is directly arranged on the inner wall of the air inlet pipeline 30, so that the weight of the whole device is prevented from being increased, and the production cost is also reduced.

As shown in fig. 1, the oil-water guiding structure may be a spring 71 disposed in the air intake duct 30, and an axis of the spring 71 is substantially parallel to or coincides with an axis of the air intake duct 30. The design utilizes the characteristic of spiral extension of the spring 71 to realize oil-water diversion, is convenient for material taking and reduces the manufacturing cost. Note that the use of the spring 71 is not based on its elastic function.

The device can also be provided with a valve 80 for controlling the opening and closing and the opening amplitude of the hot gas outlet 21 and/or the oil-water outlet 32. The valve 80 is arranged at the hot gas outlet 21 and/or the oil water outlet 32 to keep the pipeline airtight when the discharge is not needed. In addition, the valve at the hot gas outlet 21 can control the hot gas discharging speed, and further control the spiral passing speed of the gas in the vortex forming pipe 20, and further control the cooling speed and the cooling degree of the gas, and play a role in controlling the temperature of the cold gas output by the cold gas outlet 11.

In addition, the device body 100 further includes an integrated outlet 90, and both the oil-water outlet 32 and the hot-gas outlet 21 are communicated with the integrated outlet 90. The two discharge ports are communicated with one place, so that the whole device can be simplified, the discharged hot air can be used for pushing the discharge of oil and water, and the oil and water discharge efficiency is improved.
