Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a compressor with efficient heat dissipation function. Background Technology

[0002] Air compressors, as mechanical devices that compress air into high-pressure gas, are widely used in many fields such as industrial production, automobile manufacturing, medical equipment, food processing, and mining machinery. Their working principle involves using an electric motor or engine to drive the compressor, compressing air to a higher pressure, thereby enabling air storage and utilization. The equipment mainly consists of an electric motor, compressor, air tank, control system, and various accessories.

[0003] During the operation of an air compressor, compressed air releases a large amount of heat. If heat dissipation is insufficient, the equipment can easily overheat, which will not only adversely affect the compressor's performance but also shorten its service life. In particular, reciprocating compressors are prone to thermal expansion of their core components, such as cylinders and pistons, under high-temperature environments. This can lead to accelerated wear of components and, in severe cases, even equipment failure.

[0004] In view of this, in order to effectively solve the above-mentioned technical problems, this application proposes a compressor with efficient heat dissipation function. Utility Model Content

A hollow first end cover and a cooling fan connected to the drive are sequentially fixedly installed at one end of the motor. A hollow second end cover and a cooling fan connected to the drive are sequentially fixedly installed at the opposite end of the motor. Two sets of cylinder assemblies are respectively installed on the side of the first end cover and the side of the second end cover, including a first cylinder assembly, a second cylinder assembly, a third cylinder assembly, and a fourth cylinder assembly. Each set of cylinder assemblies includes a cylinder liner, a valve plate assembly, and an air passage end cover that are sequentially installed in the direction away from the motor.

[0006] The motor is provided with a first liquid cooling channel and a second liquid cooling channel; the first end cover is provided with a first liquid inlet channel and a first liquid outlet channel; the second end cover is provided with a second liquid inlet channel and a second liquid outlet channel; and each cylinder assembly is provided with an annular liquid cooling channel in its cylinder liner.

[0008] As a further supplement to this utility model, a water channel sealing ring A is provided at the connection between the motor and the liquid cooling channel of the first end cover, and at the connection between the motor and the liquid cooling channel of the second end cover.

[0009] As a further supplement to this utility model, a water passage sealing ring B is provided at the connection between the liquid cooling channel of the first end cover and the cylinder liner and at the connection between the liquid cooling channel of the second end cover and the cylinder liner.

[0010] As a further supplement to this utility model, the liquid cooling channel connection between the cylinder liner and the valve plate assembly is provided with sealing ring C and sealing ring D respectively.

[0011] As a further supplement to this utility model, each cylinder assembly is provided with a cam piston assembly, which is driven by a motor.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] This invention comprehensively solves the problems of low heat dissipation efficiency and easy component damage in traditional compressors through a cooling fan, integrated liquid cooling channel design, parallel cooling of multiple cylinder components, and multiple sealing technologies. It achieves a significant improvement in heat dissipation efficiency and extends the lifespan of key components such as cylinder components and motors. Specific beneficial effects include:

[0017] First, this utility model installs cooling fans at both ends of the motor to enhance the heat dissipation of the motor.

[0018] Secondly, this invention features an integrated liquid cooling channel within the motor, end cover, and cylinder assembly, forming a complete cooling path that includes an inlet channel, an outlet channel, and the liquid cooling channel itself. The coolant directly contacts the heat sources of the motor and cylinder assembly, utilizing the liquid's high thermal conductivity to rapidly absorb heat, thus avoiding the low efficiency of traditional air cooling. The integrated design of the liquid cooling channel with the mechanical structure reduces external piping and lowers the risk of leakage.

[0019] Third, this utility model sets water sealing rings at multiple connection points of the liquid cooling channel, which effectively prevents coolant leakage, reduces the decrease in compressor cooling efficiency and component corrosion caused by leakage, and reduces maintenance frequency.

[0020] Fourth, this invention designs a liquid pump, radiator, liquid tank, and liquid cooling channel, forming a circulating liquid cooling loop of "liquid tank → liquid pump → motor / cylinder assembly → radiator → liquid tank". The coolant can be continuously supplied in a circulating manner, ensuring stable equipment temperature under high load conditions. Compared to air-cooled systems, energy consumption is reduced by approximately 40%, minimizing energy waste. This invention also reduces reliance on external cooling equipment, making it more suitable for complex operating environments. Attached Figure Description

Detailed Implementation

In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1-4 This utility model provides a compressor with efficient heat dissipation function, which includes a motor 1. A hollow first end cover 2 and a cooling fan 4 are sequentially fixedly installed at one end of the motor 1. A hollow second end cover 3 and a cooling fan 4 are sequentially fixedly installed at the opposite end of the motor 1. An end cover plate 12 is provided at the end of the first end cover 2 away from the motor 1 and the end of the second end cover 3 away from the motor 1, respectively. The end cover plate 12 is used to prevent foreign objects from entering the first end cover 2 and the second end cover 3 and affecting the operation of the cooling fan 4. Two sets of cylinder assemblies are respectively installed on the side of the first end cover 2 and the side of the second end cover 3, which include a first cylinder assembly 51, a second cylinder assembly 52, a third cylinder assembly 53 and a fourth cylinder assembly 54. Each set of cylinder assemblies is provided with a cam piston assembly 10, which is driven by the motor 1.

[0029] Each cylinder assembly includes a cylinder liner 501, a valve plate assembly 502, and an air passage end cap 503, which are installed in sequence away from the motor 1. The air passage end caps 503 of the first cylinder assembly 51 and the third cylinder assembly 53, as well as the air passage end caps 503 of the second cylinder assembly 52 and the fourth cylinder assembly 54, are respectively connected by a connecting pipe assembly 11.

[0030] The motor 1 is provided with a first liquid cooling channel 1a and a second liquid cooling channel 1b; the first end cover 2 is provided with a first liquid inlet channel 2a and a first liquid outlet channel 2b; the second end cover 3 is provided with a second liquid inlet channel 3a and a second liquid outlet channel 3b; and each cylinder liner 501 of each cylinder assembly is provided with an annular liquid cooling channel 5a.

[0031] The first liquid cooling channel 1a of the motor is connected to the first liquid inlet channel 2a, the second liquid inlet channel 3a, the liquid inlet of the annular liquid cooling channel 5a of the first cylinder assembly 51, the liquid inlet of the annular liquid cooling channel 5a of the second cylinder assembly 52, the liquid inlet of the annular liquid cooling channel 5a of the third cylinder assembly 53, and the liquid inlet of the annular liquid cooling channel 5a of the fourth cylinder assembly 54, respectively; the second liquid cooling channel 1b of the motor is connected to the first liquid outlet channel 2b, the second liquid outlet channel 3b, the liquid outlet of the annular liquid cooling channel 5a of the first cylinder assembly 51, the liquid outlet of the annular liquid cooling channel 5a of the second cylinder assembly 52, the liquid outlet of the annular liquid cooling channel 5a of the third cylinder assembly 53, and the liquid outlet of the annular liquid cooling channel 5a of the fourth cylinder assembly 54, respectively.

[0032] The present invention also includes a liquid pump 13, a radiator 14 and a liquid tank 15; wherein the liquid pump 13 is connected to the first liquid inlet channel 2a through a pipeline, and the radiator 14 is connected to the second liquid outlet channel 3b through a pipeline; the radiator 14, the liquid tank 15 and the liquid pump 13 are connected in sequence through pipelines.

[0033] The working principle of this utility model's air-cooled structure is as follows: the motor 1 drives the cooling fans 2 at both ends to enhance the heat dissipation of the motor 1.

[0034] The working principle of this utility model's liquid cooling circulation structure is as follows: the liquid pump 13 draws coolant from the liquid tank 15 and transports it through pipelines to the first liquid inlet channel 2a of the first end cover 2 of the motor 1. The coolant enters from the first liquid inlet channel 2a into the annular liquid cooling channel 5a of the first cylinder assembly 51, the annular liquid cooling channel 5a of the second cylinder assembly 52, and the first liquid cooling channel 1a of the motor, respectively, to cool the first cylinder assembly 51. The second cylinder assembly 52 and the motor 1 are cooled. After the coolant flows out of the first liquid cooling channel 1a of the motor, it enters the annular liquid cooling channel 5a of the third cylinder assembly 53 and the annular liquid cooling channel 5a of the fourth cylinder assembly 54 through the second liquid inlet channel 3a to cool the third cylinder assembly 53 and the fourth cylinder assembly 54. At the same time, after the coolant flows out of the annular liquid cooling channel 5a of the first cylinder assembly 51 and the annular liquid cooling channel 5a of the second cylinder assembly 52, it flows out through the first liquid outlet channel 2b and enters the second liquid cooling channel 1b of the motor to further cool the motor 1. Then, it merges with the coolant flowing out of the annular liquid cooling channel 5a of the third cylinder assembly 53 and the annular liquid cooling channel 5a of the fourth cylinder assembly 54 and flows out through the liquid outlet channel 3b. The cooled liquid flows out and enters radiator 14 through pipes. Radiator 14 consists of numerous fine heat dissipation pipes or fins. The coolant flows through these pipes or fins, dissipating heat to the surrounding environment through heat exchange with the outside air. The cooled liquid then enters liquid tank 15 through pipes, completing one cycle. The cycle continues, and liquid pump 13 continuously operates, driving the coolant to circulate continuously, ensuring that the equipment is continuously and effectively cooled during operation.

[0035] Water passage sealing rings A6 are respectively provided at the liquid cooling channel connection between motor 1 and first end cover 2, and at the liquid cooling channel connection between motor 1 and second end cover 3. Water passage sealing rings B7 are respectively provided at the liquid cooling channel connection between first end cover 2 and cylinder liner 501, and at the liquid cooling channel connection between second end cover 3 and cylinder liner 501. The water passage sealing rings A6 and B7 are used to prevent liquid leakage and improve the operational stability of the liquid cooling structure.

[0036] The connection between the cylinder liner 501 and the valve plate assembly 502 in the liquid cooling channel is provided with a sealing ring C8 and a sealing ring D9, respectively. The sealing rings C8 and D9 are used to improve air tightness and increase the stability of the compressed air process of this invention.

[0037] Furthermore, the intake and exhaust processes of this invention are the core components for achieving air compression and delivery. The intake process occurs when the cam piston assembly 10 moves downwards within the cylinder assembly (intake stroke), causing the pressure within the cylinder assembly to decrease below the intake pressure. At this time, the intake valve (mounted on the air passage end cover 503) is opened, allowing outside air to enter the cylinder assembly. The exhaust process occurs when the exhaust valve opens: as the cam piston assembly 10 begins to move upwards (compression stroke), the air within the cylinder assembly is compressed, increasing the pressure. When the pressure exceeds the pressure in the exhaust passage, the exhaust valve (also mounted on the air passage end cover 503) is opened.

[0038] The air passage end cover 503 has an air inlet channel and an air outlet channel connected to the cylinder assembly, which are the paths for air to enter and exit the cylinder assembly.

[0039] Compressed air is discharged from the cylinder assembly through the exhaust passage on the air passage end cap 503. The exhaust passage delivers the compressed air to the air tank or other equipment that requires high-pressure air. The cam piston assembly 10 continues to move upward, completely expelling the compressed air from the cylinder assembly, and then moves downward again to begin the next intake stroke.

[0040] Valve plate 502 is used to control the opening and closing of the intake and exhaust valves to ensure that gas enters and exits the cylinder assembly 5 at the correct time.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
