Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a separate heat dissipation device for air compressors. Background Art

[0002] Air compressor is an important industrial equipment, widely used in various industries. Air compressor is usually composed of compression components, power components, cooling system, controller, filtration system, exhaust valve and air tank, etc.; the compression components include compressor head, crankshaft, connecting rod and plunger. The compressor head is the core component of compressed air. The crankshaft, connecting rod and plunger can provide good air sealing and strong compression capacity; the power components include motor or diesel engine, which can provide power for the compressor head; the cooling system includes fan and heat exchanger, which can dissipate heat for the compressor head so that the compressor head can operate at normal temperature; the controller is used to monitor and adjust the operating status of each component of the air compressor; the filtration system is used to filter and remove solid particles, moisture, grease and other impurities in the air; the exhaust valve can send the compressed air to the air tank; the air tank is used to store compressed air and output compressed air to meet the needs of the equipment.

[0003] Chinese patent document CN210317758U discloses an integrated permanent magnet synchronous screw air compressor, including: a permanent magnet motor, a machine head, an oil and gas barrel, an oil and gas separator, a heat exchanger, an air storage tank, and an oil filter; it is characterized in that it also includes: a frame, having a top plate and a middle accommodating space; the permanent magnet motor, the machine head, the oil and gas barrel, the oil and gas separator, the heat exchanger, and the oil filter are all fixedly installed above the top plate; the air storage tank is fixedly placed inside the middle accommodating space.

[0004] In the technical solution disclosed in the above patent document, the heat dissipation device of the air compressor is almost integrated. When the fan or heat exchanger of the heat dissipation device needs to be repaired or cleaned separately, the fan and the heat exchanger can only be disassembled for repair or cleaning. Disassembling one will affect the other, resulting in cumbersome and inconvenient operation and affecting efficiency; and connecting the fan and the heat exchanger together will cause the hot air from the heat exchanger to continuously blow on the fan motor bearing. After long-term operation, the lubricating oil inside the motor bearing is prone to oxidation and deterioration. The deteriorated lubricating oil will produce acidic substances and some insoluble substances and precipitates, such as sludge, paint film, etc.; sludge is a black-gray colloidal soft precipitate that will accelerate the deterioration of the lubricating oil; paint film is a gray-yellow to brown-black hard film that is hard and sticky after adhering to the metal surface and is not easy to remove, affecting lubrication. Long-term operation will cause the internal temperature of the motor bearing to be too high, reducing the service life.

[0005] Therefore, how to design a separate heat dissipation device for an air compressor that can prevent the fan and the heat exchanger from contacting each other and is arranged in the same sufficiently large and relatively sealed space, so that the fan or the heat exchanger can be repaired and cleaned separately, is a technical problem that has not yet been solved in the prior art.

[0039] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0040] This embodiment provides a separate heat dissipation device for an air compressor, which is suitable for being assembled in an air compressor. Figure 1-5 As shown, the air compressor includes: a head 1, a motor 2, an oil and gas barrel 3, an oil filter 4, a heat exchanger 5, a fan 6, an air storage tank 7, a heat exchange space 8 and a frame structure; wherein the heat exchanger 5 is connected in series between the head 1 and the oil and gas barrel 3; the heat exchange space 8 is a relatively sealed space, and is equipped with a detachable top plate and side plates; the heat exchange space 8 is formed inside the frame structure, and has a first mounting position 51 for mounting the heat exchanger 5, and a second mounting position 61 for mounting the fan 6, and the first mounting position 51 and the second mounting position 61 are arranged at a certain distance; the frame structure includes a bottom plate 9, a side plate and a top plate, and the bottom plate 9, the side plate and the top plate form a middle accommodating space.

[0041] When installing the heat exchanger 5 and the fan 6 on the air compressor, the heat exchanger 5 is installed inside the first installation position 51, and the fan 6 is installed inside the second installation position 61, so that the heat exchanger 5 and the fan 6 do not touch each other and are relatively far away. When it is necessary to repair or clean the heat exchanger 5 or the fan 6 of the air compressor separately, the top plate or the side plate of the corresponding installation position is removed, and the heat exchanger 5 or the fan 6 is repaired or cleaned separately; if necessary, the side plate of the heat exchange space 8 can be removed, and the heat exchange space 8 can be entered to repair or clean the heat exchanger 5 or the fan 6 separately.

[0042] The separate heat dissipation device for the air compressor of this embodiment can install the heat exchanger 5 and the fan 6 separately at a certain distance, thereby avoiding the problem that the heat exchanger 5 and the fan 6 are connected together and run for a long time, which will cause the internal temperature of the motor bearing to be too high and thus reduce the service life; and when maintenance or cleaning is needed, they can be repaired or cleaned separately without disassembling the heat exchanger 5 and the fan 6, thereby avoiding cumbersome operations and improving the efficiency of maintenance or cleaning.

[0043] The heat exchange space 8 is located inside the middle accommodating space and at a corner of the middle accommodating space. Being arranged at this position can facilitate maintenance or cleaning by maintenance personnel.

[0044] The first installation position 51 is disposed at a side wall position of the heat exchange space 8 facing outward, and the second installation position 61 is disposed at a top position of the heat exchange space 8 .

[0045] After the heat exchanger 5 is installed in the first installation position 51, it also includes an outer protective plate, which is installed in the first installation position 51 and is located on the outward side. The outer protective plate can protect the heat exchanger 5 from damage caused by collision.

[0046] Preferably, Figure 2 As shown, it also includes an inspection port 81, on which a maintenance plate is detachably installed. When it is necessary to enter the heat exchange space 8 to repair or clean the heat exchanger 5 or the fan 6, the inspection plate can be removed, and the heat exchange space 8 can be entered through the inspection port 81 to repair or clean the heat exchanger 5 or the fan 6.

[0047] Specifically, the frame structure also includes: a plurality of vertical beams 91 arranged on the four edges of the base plate 9, at least two bearing members 93 arranged on the base plate 9 for bearing the oil and gas barrels 3, and at least four first fixing members 94 and at least four second fixing members 95 arranged on the top surface of the base plate 9 for fixing the motor 2 and the gas tank 7; the frame structure of this design can make the overall stability and bearing capacity of the frame stronger.

[0049] The motor 2, oil and gas barrel 3, gas storage tank 7 and heat exchange space 8 are all fixedly mounted on the top surface of the base plate 9. This installation position has a more reasonable structure, better compactness and better heat dissipation.

The protection box 11 can protect the controller 10 to prevent the controller 10 from being damaged so that the air compressor cannot work normally.

[0051] There are two fans 6 installed side by side at the second installation position 61. The two fans 6 can increase the air intake, so that the wind that passes through the heat exchanger 5 to take away the heat is larger, and the cooling effect is better.

[0052] In the separate heat dissipation device for air compressor in this embodiment, when installing the heat exchanger 5 and the fan 6 in the air compressor, the heat exchanger 5 is installed inside the first installation position 51, and the fan 6 is installed inside the second installation position 61, so that the heat exchanger 5 and the fan 6 do not touch each other and are relatively far away. When it is necessary to repair or clean the heat exchanger 5 or the fan 6 of the air compressor separately, the top plate or the side plate of the corresponding installation position is removed, and the heat exchanger 5 or the fan 6 is repaired or cleaned separately; if necessary, the side plate of the heat exchange space 8 can be removed, and the heat exchanger 5 or the fan 6 can be entered into the heat exchange space 8 to repair or clean it separately.

[0053] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of this innovative technical solution.
