Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a water cooling device on an air compressor. Background Art

[0002] The full name of air compressor is air compressor, which is a device used to compress gas. The working principle of air compressor is to suck in and compress air through the compressor, so that its pressure rises and is stored in the gas container. When it is needed, the compressed air is released and transmitted to the required place through the pipeline. During the operation of the air compressor, the temperature of its own oil circuit will rise. Some air compressors are equipped with cooling fans to cool the oil circuit. The cooling fan can circulate the air beside the oil circuit, so that the surrounding air and the oil circuit can exchange heat to take away the heat of the oil circuit and reduce the temperature of the oil circuit. However, when the indoor temperature is high and the machine is running and generating heat, resulting in a high ambient temperature near the cooling fan, the temperature of the air blown by the cooling fan is also high, and the oil circuit temperature cannot be quickly reduced to a safe temperature, which may cause the oil temperature to be too high and cause the air compressor to shut down.

[0003] In response to the above-mentioned problem, a patent document with authorization announcement number CN219888221U announces a water-cooling and cooling device for an air compressor, comprising a base for installation on the air inlet end of a cooling fan, a horizontal coil installed on the base, a circulating water pump connected to the horizontal coil through a pipeline, and a refrigerator connected to the horizontal coil through a pipeline, the horizontal coil, the circulating water pump and the refrigerator are connected in sequence to form a cooling circuit; the base comprises a square frame, a mounting portion for installing the square frame on the cooling fan, and support rods cross-embedded in the square frame. The water-cooling and cooling device for an air compressor is suitable for use when the air compressor oil circuit needs to be quickly cooled down, and can be conveniently installed on the cooling fan of the air compressor as an additional cooling device to assist the cooling fan to quickly reduce the temperature of the air compressor oil circuit.

[0004] In actual use, it was found that the above-mentioned related schemes still have at least the following shortcomings: in the process of using the horizontal coil to cool the air blown out by the cooling fan and then blowing the cooled air to the surface of the air compressor oil circuit, since the air passes through and contacts the horizontal coil for a relatively short time, it is easy to cause the heat in the air to not be fully absorbed by the cooling water in the horizontal coil, resulting in poor cooling effect on the air. As a result, the temperature of the air blown to the surface of the oil circuit of the air compressor will still be relatively high, and the heat dissipation of the air compressor oil circuit is not ideal.

[0005] Therefore, it is necessary to provide a new water cooling device on an air compressor to solve the above technical problems. Utility Model Content

A water cooling device on an air compressor comprises: a cooling fan 1 installed and fixed on the original oil circuit of the air compressor, and a wind collecting cover 2 and a water cooling seat 3 arranged on the cooling fan 1. The cooling fan 1 is used to cool the oil circuit of the air compressor by air, wherein:

[0024] The wind collecting hood 2 is fixedly installed at the air outlet end of the cooling fan 1. The side of the wind collecting hood 2 close to the cooling fan 1 is an open structure. The wind collecting hood 2 is used to collect the air exhausted when the cooling fan 1 is running. The water cooling seat 3 is fixedly installed on the outer wall of the wind collecting hood 2 on the side away from the cooling fan 1. An air channel 4 is opened on one side of the water cooling seat 3. The air channel 4 is used to exhaust the cooled air so as to blow the cooled air to the oil circuit of the air compressor for cooling. An annular water cavity 5 is opened in the water cooling seat 3. The annular water cavity 5 contains coolant. It should be noted that the coolant is filled in the annular water cavity 5. A circulation mechanism for controlling the circulation of the coolant is arranged on the water cooling seat 3. The circulation mechanism includes a circulating water pump 8, a refrigerator 9, and a liquid suction pipe 1. 0, the liquid infusion pipe 11 and the liquid return pipe 12, the circulating water pump 8 and the refrigerator 9 are all arranged below the water cooling seat 3, one end of the liquid suction pipe 10 is fixedly connected to the suction end of the circulating water pump 8, and the other end of the liquid suction pipe 10 extends into the annular water cavity 5, one end of the liquid infusion pipe 11 is fixedly connected to the discharge end of the circulating water pump 8, and the other end of the liquid infusion pipe 11 is fixedly connected to the inlet end of the refrigerator 9, one end of the liquid return pipe 12 is fixedly connected to the discharge end of the refrigerator 9, and the other end of the liquid return pipe 12 extends to the annular water cavity 5, and the end of the liquid suction pipe 10 located in the annular water cavity 5 is lower than the end of the liquid return pipe 12 located in the annular water cavity 5. The circulating water pump 8 can be used to pump the cooling liquid in the annular water cavity 5 to the refrigerator through the liquid suction pipe 10 and the liquid infusion pipe 11 9, the cooling liquid can be cooled by the refrigerator 9, so that the cooled cooling liquid can flow back to the annular water cavity 5 through the return pipe 12, and then the cooling liquid can be controlled to circulate in the annular water cavity 5, and it can be ensured that the cooling liquid has a low stability for effectively absorbing the heat in the air. A plurality of heat-conducting air pipes 6 are fixedly installed in the annular water cavity 5, and the plurality of heat-conducting air pipes 6 are distributed in an annular shape with equal spacing. One end of the plurality of heat-conducting air pipes 6 extends into the air collecting hood 2.

The other ends of the plurality of heat-conducting air pipes 6 are fixed. A heat-conducting air pipe 27 is installed, and one end of multiple heat-conducting air pipes 27 away from the corresponding heat-conducting air pipe 16 extends into the air channel 4. During the process of the air after preliminary cooling flowing inside the multiple heat-conducting air pipes 27, the heat can be further transferred to the coolant, thereby achieving the effect of secondary cooling of the air. Furthermore, by controlling the air to flow in the heat-conducting air pipe 16 and the heat-conducting air pipe 27 in turn, and finally allowing the air to be discharged from left to right through the air channel 4 (from the main viewing angle), the cooling time of the air can be increased, the air can be cooled more effectively, more heat in the air can be absorbed, and the cooling effect of the oil circuit of the air compressor can be improved.

[0025] In this embodiment, it should be noted that the circulating water pump 8 and the refrigerator 9 can be purchased on the market or customized in the factory. The electrical connection of the circuits of the circulating water pump 8 and the refrigerator 9 is an existing mature technology, so it will not be elaborated in this article.

[0026] In this embodiment, during the flow of air in the heat-conducting air pipe 6, in order to transfer more heat in the air to the coolant and improve the cooling effect on the air, a plurality of heat-conducting fins 13 distributed at equal intervals are fixedly mounted on the heat-conducting air pipe 6, and the plurality of heat-conducting fins 13 are all immersed in the coolant.

[0027] In this embodiment, during the flow of air in the heat-conducting air pipe 27, in order to transfer more heat in the air to the coolant and improve the cooling effect on the air, a plurality of heat-conducting fins 214 distributed at equal intervals are fixedly mounted on the heat-conducting air pipe 27, and the plurality of heat-conducting fins 214 are all in contact with the inner wall of the air channel 4.

[0028] In this embodiment, it should be additionally explained that the water cooling seat 3, the heat-conducting gas pipe 1 6, the heat-conducting gas pipe 2 7, the heat-conducting fin 1 13 and the heat-conducting fin 2 14 are all made of any one of aluminum alloy materials and copper materials with good thermal conductivity.

The setting of the avoidance hole will not affect the discharge of the cooled air from the air channel 4.

[0030] In this embodiment, in order to evenly diffuse the cooled cold air and blow it out from the air channel 4 and blow it toward the oil path surface of the air compressor in a comprehensive and effective manner, an air distribution plate 16 is detachably installed and fixed on the outer wall of the water cooling seat 3 on the side away from the air collecting hood 2. The air distribution plate 16 passes through the avoidance hole, and a plurality of air distribution holes 17 are evenly arranged on the air distribution plate 16, and the plurality of air distribution holes 17 are all connected to the air channel 4.

[0031] In this embodiment, in order to facilitate the disassembly and cleaning of the air distribution plate 16, the air distribution plate 16 is fixed to the outer wall of the water cooling seat 3 on the side away from the air collecting cover 2 by screw assembly.

[0032] The working principle of the water cooling device on the air compressor provided by the utility model is as follows:

[0033] During the operation of the air compressor, when it is necessary to dissipate heat from the oil circuit of the air compressor, the cooling fan 1, the circulating water pump 8 and the refrigerator 9 are started. Under the operation of the cooling fan 1, the air first enters the air collecting cover 2, and then passes through the multiple heat-conducting air delivery pipes 16 and the multiple heat-conducting air delivery pipes 27 in sequence to enter the air channel 4. By utilizing the heat conductivity of the air flowing in the multiple heat-conducting air delivery pipes 6 and the multiple heat-conducting fins 13, the heat in the air can be transferred to the coolant, thereby achieving the effect of preliminary cooling of the air. By utilizing the air after preliminary cooling to flow in the multiple heat-conducting air delivery pipes 27, the air can be cooled and cooled. In the process of internal flow, the heat conductivity of the plurality of heat-conducting fins 14 can be used to further transfer heat to the coolant, thereby achieving a secondary cooling effect on the air, and the air can flow through the heat-conducting air pipe 1 6 and the heat-conducting air pipe 2 7 in sequence, and finally the cooled low-temperature air is discharged through the air channel 4 and blown evenly and comprehensively to the oil circuit surface of the air compressor, thereby increasing the cooling time of the air, cooling the air more effectively, absorbing more heat in the air, and thus improving the cooling effect on the oil circuit of the air compressor;

[0034] In the process of cooling the oil circuit surface of the air compressor by air cooling, the cooling liquid in the annular water cavity 5 can be pumped into the refrigerator 9 through the suction pipe 10 and the infusion pipe 11 by utilizing the operation of the circulating water pump 8. The cooling liquid can be cooled by the refrigerator 9, so that the cooled cooling liquid can flow back into the annular water cavity 5 through the return pipe 12, thereby controlling the circulation of the cooling liquid in the annular water cavity 5 and ensuring that the cooling liquid has a low stability for effectively absorbing heat in the air.

[0035] Compared with the related art, the water cooling device on the air compressor provided by the utility model has the following beneficial effects:

[0036] The utility model provides a water cooling device on an air compressor, which controls the air to flow through the heat-conducting air delivery pipe 1 6 and the heat-conducting air delivery pipe 2 7 in sequence for secondary cooling, and then the cooled low-temperature air is discharged through the air channel 4 and blown evenly and comprehensively to the oil circuit surface of the air compressor, thereby increasing the cooling time of the air, cooling the air more effectively, absorbing more heat in the air, and further improving the cooling effect of the oil circuit of the air compressor.
