Description

Technical Field

[0001] This utility model relates to the field of compression equipment technology, and in particular to a compressor with a combined air-cooling and liquid-cooling heat dissipation structure. Background Technology

[0002] In industrial production, energy transmission, and gas processing, compressors, as key power equipment, are widely used in gas pressurization, transportation, and storage. With the continuous increase in the power of industrial equipment, the heat generated by compressors during operation increases significantly, especially under high-frequency, high-load conditions, where the compressor head, motor, and compressed gas all generate substantial heat. If heat is not dissipated effectively and promptly, it can easily lead to reduced compression efficiency, accelerated equipment wear, shortened service life, and even system failure. Therefore, how to achieve efficient thermal management of critical compressor components and exhaust gas has become a key technical challenge in this field.

[0003] Traditional compressors mostly employ a single air-cooled structure, drawing in ambient air through a fan to remove heat. However, their heat dissipation efficiency is limited by ambient temperature and airflow organization, making it difficult to meet the thermal management requirements of high-power compressors. Some systems incorporate liquid cooling systems to cool the motor or casing, which can improve heat exchange efficiency to some extent. However, the overall structure is complex, and the gas heat exchange and coolant heat exchange systems are usually separate, resulting in problems such as long heat exchange paths, large size, and increased energy consumption.

[0004] Therefore, there is an urgent need for a compact structure, a reasonable heat exchange path, and a coordinated heat dissipation solution that can simultaneously control the temperature of compressed gas and compressor components, so as to improve the thermal management capability and operational reliability of the compression system. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a compressor with a combined air-cooled and liquid-cooled heat dissipation structure. This compressor has a compact structure, a reasonable heat exchange path, and high operational reliability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A compressor with a combined air-cooled and liquid-cooled heat dissipation structure includes: a chassis, a compression assembly, an exhaust pipe, a heat exchanger, an air-cooled unit, and a liquid-cooled unit. The compression assembly is disposed inside the chassis and is used to compress gas and output compressed gas. One end of the exhaust pipe is connected to the compression assembly, and the other end is connected to an external exhaust port. The heat exchanger is disposed on the exhaust pipe and is used to cool the high-temperature gas discharged from the compression assembly. The air-cooled unit includes a fan installed inside the chassis and is used to guide ambient air through the heat exchanger to perform air-cooled heat exchange on the high-temperature gas. The liquid-cooled unit includes a liquid storage tank, a water pump, and a coolant pipe. The inlet end of the water pump is connected to the liquid storage tank, and the outlet end is connected sequentially to the cooling section of the compression assembly, the liquid channel of the heat exchanger, and the liquid storage tank through the coolant pipe to form a liquid-cooled circulation path and achieve liquid-cooled heat exchange on the compression assembly.

[0007] Furthermore, the chassis is equipped with an air inlet and an air outlet. The air inlet of the fan is connected to the air inlet through a fan shroud, and the air outlet of the fan is connected to the air outlet through a fan shroud, so as to guide the air to flow through the heat exchanger and then be discharged outside the chassis.

[0008] Furthermore, the fan shroud includes an inner heat dissipation shroud and an outer heat dissipation shroud. The inner heat dissipation shroud is located between the air inlet of the fan and the heat exchanger to guide the airflow through the heat exchanger. The outer heat dissipation shroud is located between the heat exchanger and the exhaust port to guide the heat-exchanged gas to be discharged outside the casing.

[0009] Furthermore, the heat exchanger is a plate-fin heat exchanger, with its gas passage connected to the exhaust pipe and its liquid passage connected to the coolant pipe, so as to achieve heat exchange between the compressed gas and the coolant respectively.

[0010] Furthermore, the coolant pipeline includes a first pipeline, a second pipeline, a third pipeline, and a fourth pipeline connected in sequence, wherein: the first pipeline connects the outlet of the water pump to the inlet of the cooling section of the compression assembly; the second pipeline connects the outlet of the cooling section of the compression assembly to the liquid inlet of the heat exchanger; the third pipeline connects the liquid outlet of the heat exchanger to the storage tank; and the fourth pipeline connects the storage tank to the inlet of the water pump.

[0011] Furthermore, the power supply terminals of both the fan and the water pump are electrically connected to the same control switch to achieve coordinated control of the air-cooled and liquid-cooled units.

[0012] Furthermore, the coolant reservoir is located inside the chassis, and a coolant inlet is provided on the chassis for replenishing coolant, which is connected to the coolant reservoir.

[0013] Furthermore, the compression assembly includes a compressor head and a volute. The compressor head contains an impeller for compressing gas, and the volute is located on one side of the compressor head and communicates with the exhaust end of the impeller to guide the compressed gas into the exhaust pipe.

[0014] The compressor with the aforementioned air-cooled and liquid-cooled synergistic heat dissipation structure integrates the compression components, air-cooled unit, and liquid-cooled unit within the chassis, and is equipped with a heat exchanger. This enables synergistic heat exchange between the compressed gas and key components. The exhaust heat is managed simultaneously by air cooling and liquid cooling, effectively improving heat dissipation efficiency. This solves the problems of insufficient heat dissipation capacity, complex structure, and high energy consumption of existing high-load compressors, thereby improving the operational reliability and thermal management performance of the equipment.

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figures 1 to 5 As shown, this application provides a compressor with a combined air-cooled and liquid-cooled heat dissipation structure, including a chassis 1, a compression assembly 2, an exhaust pipe 3, a heat exchanger 4, an air-cooled unit 5, and a liquid-cooled unit 6.

[0018] Specifically, the compression assembly 2 is installed inside the casing 1 and is used to compress the gas and output compressed gas; one end of the exhaust pipe 3 is connected to the compression assembly 2 and the other end is connected to the external exhaust port; the heat exchanger 4 is installed on the exhaust pipe 3 and is used to cool the high-temperature gas discharged from the compression assembly 2; the air-cooling unit 5 includes a fan 51, which is installed inside the casing 1 and is used to guide ambient air through the heat exchanger 4 to perform air-cooled heat exchange on the high-temperature gas; the liquid-cooling unit 6 includes a liquid storage tank 61, a water pump 62 and a coolant pipe 63, the inlet end of the water pump 62 is connected to the liquid storage tank 61, and the outlet end is connected to the cooling part of the compression assembly 2, the liquid channel of the heat exchanger 4 and the liquid storage tank 61 in sequence through the coolant pipe 63 to form a liquid-cooled circulation path and realize liquid-cooled heat exchange on the compression assembly 2.

[0019] This compressor adopts a combined air-cooling and liquid-cooling structure, which can simultaneously and efficiently cool the compression assembly 2 and the exhaust gas, significantly improving the system's heat dissipation capacity and making it suitable for high-power, high-load operating conditions. The air-cooling structure facilitates the removal of ambient heat, while the liquid-cooling system enables precise temperature control, reduces thermal stress on core components, extends equipment lifespan, and simultaneously reduces size and energy consumption, optimizing the overall system layout and operational reliability.

[0020] like Figure 1 As shown, the chassis 1 is equipped with an air inlet 11 and an air outlet 12. The air inlet of the fan 51 is connected to the air inlet 11 through a fan shroud 7, and the air outlet of the fan 51 is connected to the air outlet 12 through the fan shroud 7, so as to guide the airflow through the heat exchanger 4 and then discharge it to the outside of the chassis 1. This scheme optimizes the air-cooling path design, forms a stable and effective air heat exchange channel, and enhances the ventilation and cooling effect inside the compressor. Using the fan shroud 7 to guide the airflow direction helps to improve cooling efficiency and reduce local heat accumulation, further ensuring the thermal stability and system reliability of the compression assembly 2 under high load operation. Among them, the fan 51 is fitted with a fan cover 52 to improve the airflow efficiency and avoid external interference.

[0021] like Figure 5 As shown, the fan shroud 7 includes an inner heat dissipation shroud 71 and an outer heat dissipation shroud 72. The inner heat dissipation shroud 71 is located between the air inlet 11 of the fan 51 and the heat exchanger 4, guiding the airflow through the heat exchanger 4. The outer heat dissipation shroud 72 is located between the heat exchanger 4 and the exhaust port 12, guiding the heat-exchanged gas to the outside of the casing 1. By adopting a segmented air-guiding shroud structure, the airflow path can be effectively controlled, improving heat dissipation efficiency and the consistency of airflow velocity, thereby enhancing the temperature control capability of the compression system. The layered structure also reduces fan noise leakage and makes maintenance more convenient.

[0022] like Figure 2 and Figure 3 As shown, heat exchanger 4 is a plate-fin heat exchanger. Its gas passage is connected to the exhaust pipe 3, and its liquid passage is connected to the coolant pipe 63, to achieve heat exchange between the compressed gas and the coolant respectively. Using a plate-fin heat exchanger as the gas-liquid heat exchange device has advantages such as compact structure, high heat transfer efficiency, and large heat exchange area per unit volume, enabling efficient heat dissipation within a limited space. Its gas passage is directly connected to the exhaust pipe 3, reducing intermediate connection losses and improving heat exchange response speed. Simultaneously, the liquid passage is connected to the coolant pipe 63, allowing the liquid cooling system to fully absorb heat from the compressed gas, thereby significantly reducing the exhaust temperature, extending the life of the compression components, and improving system operational stability.

[0023] The coolant pipeline 63 includes a first pipeline 631, a second pipeline 632, a third pipeline 633, and a fourth pipeline 634 connected in sequence. Specifically: the first pipeline 631 connects the outlet of the water pump 62 to the inlet of the cooling section of the compressor assembly 2; the second pipeline 632 connects the outlet of the cooling section of the compressor assembly 2 to the liquid inlet of the heat exchanger 4; the third pipeline 633 connects the liquid outlet of the heat exchanger 4 to the storage tank 61; and the fourth pipeline 634 connects the storage tank 61 and the inlet of the water pump 62. Specifically, the first pipeline 631 prioritizes cooling the compressor assembly 2, ensuring good heat dissipation capacity from the initial stage of operation; the second pipeline 632 introduces the cooled coolant into the heat exchanger 4 for secondary heat dissipation, further reducing the liquid temperature; the third pipeline 633 returns the relatively cooled liquid to the storage tank 61, preparing for the next cooling cycle; and the fourth pipeline 634 transports the cooled coolant to the next cycle. This design effectively reduces the thermal load on the compression components, extends the lifespan of critical components, and enhances the operational stability and thermal management capabilities of the entire liquid cooling system.

[0024] Both the power supply terminals of the fan 51 and the water pump 62 are electrically connected to the same control switch to achieve coordinated control of the air-cooled and liquid-cooled units 6. This eliminates the need to control the two cooling methods separately, reducing the complexity of the control system and the probability of errors. Simultaneously, it ensures that the air-cooled and liquid-cooled systems can work together to quickly dissipate heat under high-temperature loads or during the initial stages of operation, effectively preventing damage caused by localized overheating or temperature fluctuations in the compressor assembly 2. Furthermore, this coordinated approach helps maintain a stable thermal management rhythm, extends the lifespan of critical components, and improves the safety and reliability of the equipment.

[0025] like Figure 3 As shown, the coolant reservoir 61 is located inside the chassis 1, and a coolant inlet 13 for replenishing coolant is provided on the chassis 1, which communicates with the coolant reservoir 61. Placing the coolant reservoir 61 inside the chassis 1 saves external installation space, improves system integration, reduces the risk of coolant exposure to the external environment, and enhances system sealing and safety. The coolant inlet 13 improves maintenance convenience, allowing users to quickly and accurately replenish coolant and avoid reduced heat dissipation efficiency or pump dry running due to insufficient coolant level.

[0026] like Figure 2 As shown, the compression assembly 2 includes a compressor head 21 and a volute 22. The compressor head 21 houses an impeller for compressing gas, and the volute 22 is located on one side of the compressor head 21 and communicates with the exhaust end of the impeller to guide the compressed gas into the exhaust pipe 3. This structure, by combining the compressor head 21 and the volute 22 in the compression assembly 2, makes the compression process more efficient and stable. The high-speed rotation of the impeller built into the compressor head 21 enables continuous pressurization of the gas, while the volute 22 provides a smooth flow path, significantly reducing pressure loss and flow noise during the exhaust process and improving the overall energy efficiency of the system.

Various modifications to these embodiments will be readily apparent to those skilled in the art.
