Description

Technical Field

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

[0002] Air compressors play an important role in industrial applications. However, long-term operation can cause the temperature of the equipment to rise, affecting its performance and lifespan. To ensure the normal operation of air compressors in high-temperature environments, it is necessary to cool down the air compressors.

[0003] Among them, air compressors need to be lubricated with lubricating oil during operation. The temperature of the lubricating oil will rise with the operation of the air compressor. If the temperature of the lubricating oil is too high, it is not conducive to the cooling of the air compressor and also not conducive to the long-term operation of the compressor. By cooling down the lubricating oil, the compressor can be cooled synchronously. In the prior art, an oil pump is used to drive the lubricating oil to circulate outside the compressor, and the lubricating oil circulating in the pipeline is cooled by air cooling or water cooling. In the above methods, the cooling efficiency of the lubricating oil is low. When the temperature of the environment where the air compressor is located is high or the air compressor is under high load and continuous operation conditions, the conventional air cooling or water cooling methods cannot meet the cooling requirements of the lubricating oil. Summary of the Utility Model

[0004] Aiming at the above-mentioned existing technical problems, the purpose of the utility model is to propose a cooling device for a compressor, which cools down the lubricating oil by means of air cooling and heat exchange of a heat transfer medium, has high cooling efficiency, can effectively meet the cooling requirements of the lubricating oil of the compressor in high-temperature environments or under high load and continuous operation conditions, and has strong practicability.

[0005] The technical solution of the utility model is realized as follows: A cooling device for a compressor includes a base, a cooling fan, an energy storage container, heat conducting rods, a heat conducting sleeve, and a heat conducting oil pipe.

[0006] The base is provided with a top-open air supply chamber, and an air supply port communicating with the air supply chamber is provided on the side wall of the base.

[0007] The cooling fan is arranged on the base and has an air supply end connected to the air supply port.

[0008] The energy storage container is arranged on the base and has a bottom plate covering the open mouth of the air supply chamber; a heat transfer medium for heat and cold exchange is arranged inside the energy storage container.

[0009] A plurality of the heat conducting rods are inserted through the bottom plate, having a first end extending into the interior of the energy storage container and a second end extending into the air supply chamber.

[0010] Two sets of the heat conduction sleeves are arranged in parallel inside the energy storage container, having a first end exposed above the top of the energy storage container and a second end communicating with the air supply chamber;

[0011] The heat conduction oil pipe penetrates and extends between the two sets of heat conduction sleeves, having a helically extending section formed in the heat conduction sleeve, and having a connecting section formed in the air supply chamber, and having two oil inlet and outlet ports extending out from the first end of the heat conduction sleeve.

[0012] Further, the heat conduction sleeve penetrates through the bottom plate and is hermetically connected to the bottom plate through a flange.

[0013] Further, heat dissipation fins are distributed on the outer wall of the heat conduction sleeve.

[0014] Further, a heat insulation layer is provided on the outer wall of the energy storage container.

[0015] Further, the heat exchange medium is cooling water, ice cubes or heat conduction oil.

[0016] Further, the second end of the heat conduction rod blocks the air outlet side of the air supply port.

[0017] Further, the top of the energy storage container is provided with an open mouth; the cooling device includes a cover plate for covering the open mouth at the top of the energy storage container; and avoidance holes are provided on the cover plate corresponding to the heat conduction sleeves.

[0018] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0019] 1. By the cooperative use of the heat conduction sleeves in the utility model, the lubricating oil circulates in the heat conduction oil pipe, and the heat carried by the lubricating oil is conducted to the heat conduction oil pipe. The air flow is generated by the heat dissipation fan, and the air flow enters the heat conduction sleeves through the air supply chamber and is in full contact with the helically extending section of the heat conduction oil pipe to cool down the heat conduction oil pipe and the lubricating oil. At the same time, the heat conduction sleeve exchanges heat with the heat exchange medium in the energy storage container to be able to cool down the internal space of the heat conduction sleeve, and further cools down the heat conduction oil pipe and the lubricating oil efficiently through the heat exchange method. The combination of the above methods cools down the lubricating oil by means of air cooling and heat exchange of the heat exchange medium, with high cooling efficiency, effectively meeting the cooling requirements of the lubricating oil of the compressor under high-temperature environments or under high-load and continuous operation conditions, and having strong practicability.

[0020] 2. By the cooperative use of the helically extending section in the utility model, the helically extending section can increase the contact area between the heat conduction oil pipe and the air flow and can increase the heat exchange area in the heat conduction sleeve, which is beneficial to the efficient heat exchange and cooling of the heat conduction oil pipe, and has strong practicability.

[0021] 3. Through the coordinated use of the heat conduction rod, the heat conduction rod can conduct heat exchange with the heat exchange medium in the energy storage container. The air flow entering the air supply chamber through the air supply opening contacts the heat conduction rod and conducts heat exchange, so as to reduce the temperature of the air flow and further improve the cooling efficiency of the heat conduction oil pipe and the lubricating oil.

[0032] The preferred embodiments of the present utility model will be described in detail below with reference to the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0033] As Figures 1-8Shown is a cooling device for a compressor according to this embodiment. The cooling device is placed beside the air compressor and is used for cooling the air compressor. The cooling device includes structural components such as a base 1, a cooling fan 3, a storage container 2, a heat conducting rod 4, a heat conducting sleeve 5, and a heat conducting oil pipe 6. Among them, the base 1 is fixedly installed on the ground by bolts. An air supply cavity 11 with an open top is machined on the base 1, and an air supply port 12 communicating with the air supply cavity 11 is machined on the side wall of the base 1. The aforementioned cooling fan 3 is fixedly installed on the base 1 and has an air supply end connected to the air supply port 12. When the cooling fan 3 operates, it conveys an air flow into the air supply cavity 11 through the air supply port 12.

[0034] The aforementioned storage container 2 is installed on the base 1 by bolts and has a bottom plate 21 that covers the open top of the air supply cavity 11. The bottom plate 21 is hermetically connected to the top surface of the base 1 and seals the open top of the air supply cavity 11. A heat exchange medium for heat and cold exchange is placed inside the storage container 2. The heat exchange medium in this embodiment is a cold source and can be cooling water, ice cubes, ice slurry, or heat conducting oil. In practical applications, considering the cost, the heat exchange medium is preferably ice cubes. A discharge pipe 22 is installed on the side wall of the storage container 2. Through the discharge pipe 22, the heat exchange medium inside the storage container 2 can be discharged.

[0035] The aforementioned heat conducting rod 4 is made of a metal heat conducting material. The several heat conducting rods 4 penetrate through the bottom plate 21 and have a first end extending into the interior of the storage container 2 and a second end extending into the air supply cavity 11. Through the above structural design, the first end of the heat conducting rod 4 can contact the heat exchange medium in the storage container 2 and transfer the cold quantity to the second end of the heat conducting rod 4 by means of heat conduction, thereby enabling heat and cold exchange with the heat exchange medium in the storage container 2. The heat conducting rod 4 is fixed on the bottom plate 21 by means of sealed welding. In this embodiment, in the specific structural design, the second end of the heat conducting rod 4 blocks the air outlet side of the air supply port 12, and the air flow entering the air supply cavity 11 through the air supply port 12 first contacts the heat conducting rod 4 to be able to reduce the temperature of the air flow by means of heat exchange.

[0036] The aforementioned heat-conducting sleeve 5 is of a hollow structure and is made of a metal heat-conducting material. The two sets of heat-conducting sleeves 5 are arranged side by side inside the energy storage container 2, and have a first end (upper end) exposed above the top of the energy storage container 2 and a second end (lower end) communicating with the air supply chamber 11. The air flow entering the air supply chamber 11 can enter the interior of the heat-conducting sleeve 5 through the second section of the heat-conducting sleeve 5. Specifically, insertion holes are machined on the bottom plate 21 corresponding to the heat-conducting sleeve 5. The heat-conducting sleeve 5 is inserted into the insertion holes from below the bottom of the energy storage container 2. A flange 51 is fixed at the lower end of the heat-conducting sleeve 5, and the heat-conducting sleeve 5 is locked and fixed to the bottom plate 21 through screws and the flange 51 to seal the insertion holes. The aforementioned heat-conducting oil pipe 6 is a copper pipe. The heat-conducting oil pipe 6 extends through between the two sets of heat-conducting sleeves 5. The heat-conducting oil pipe 6 has a helical extension section 61 formed in the heat-conducting sleeve 5, and a connecting section 62 formed in the air supply chamber 11, and two oil inlet and outlet ports 63 extending out from the first end of the heat-conducting sleeve 5.

[0037] The above-mentioned helical extension section 61 can increase the contact area between the heat-conducting oil pipe 6 and the air flow and can increase the heat exchange area in the heat-conducting sleeve 5, so as to facilitate the efficient heat exchange cooling and temperature reduction of the heat-conducting oil pipe 6, and has strong practicability.

[0038] Among the two oil inlet and outlet ports 63, one oil inlet and outlet port 63 is an oil inlet, and the other is an oil outlet. Among them, a lubricating oil inlet and a lubricating oil outlet are provided on the corresponding compressor. During specific connection, the oil outlet is connected to the lubricating oil inlet, the oil inlet is connected to the oil pump, and the lubricating oil outlet is connected to the oil pump to realize the circulating flow of the lubricating oil in the heat-conducting oil pipe 6.

[0039] In this embodiment, heat dissipation fins 52 are installed at intervals along the length direction on the outer wall of the heat-conducting sleeve 5. The heat dissipation fins 52 can increase the contact area between the outer wall of the heat-conducting sleeve 5 and the heat exchange medium. A heat preservation layer 23 is wrapped on the outer wall of the energy storage container 2 to reduce the cold quantity loss of the heat exchange medium. The top of the aforementioned energy storage container 2 is arranged in an open manner. Through this open top, heat exchange media such as ice cubes and cooling water can be put into the interior of the energy storage container 2. Among them, a cover plate 7 for covering the top opening of the energy storage container 2 is installed on the energy storage container 2. The cover plate 7 is composed of two plate bodies. Among them, notches are machined on the plate bodies. After combination, the two notches form an avoidance hole 71 adapted to the heat-conducting sleeve 5. Through the covering of the cover plate 7, the cold quantity loss of the heat exchange medium can be further reduced.

[0040] During specific use, driven by an oil pump, lubricating oil enters the heat-conducting oil pipe 6 through one of the oil inlet and outlet ports 63 and is discharged from the other oil inlet and outlet port 63, so as to realize the circulating flow of the lubricating oil in the heat-conducting oil pipe 6. During the circulating flow of the lubricating oil, the heat carried by it is conducted to the heat-conducting oil pipe 6. Start the cooling fan 3 to generate an air flow. The air flow enters the air supply cavity 11 from the air supply port 12, contacts the heat-conducting rod 4 and cools down, and then enters the heat-conducting sleeve 5 from the second end of the heat-conducting sleeve 5 through the air supply cavity 11. The air flow fully contacts the spiral extension section 61 of the heat-conducting oil pipe 6 to cool down the heat-conducting oil pipe 6 and the lubricating oil. At the same time, the heat-conducting sleeve 5 exchanges heat with the heat exchange medium in the energy storage container 2 to cool down the internal space of the heat-conducting sleeve 5, and then efficiently cools down the heat-conducting oil pipe 6 and the lubricating oil through heat exchange. The combination of the above methods cools down the lubricating oil through air cooling and heat exchange of the heat exchange medium, with high cooling efficiency, effectively meeting the cooling requirements of the lubricating oil of the compressor under high-temperature environments or under high-load and continuous operation conditions, and having strong practicability.
