Description

Technical Field

[0001] This utility model relates to the technical field of air-cooled chiller units, specifically an energy-saving structure for air-cooled chiller units based on multi-stage fin heat dissipation. Background Technology

[0002] Air-cooled chillers based on multi-stage finned heat dissipation are refrigeration equipment that improves heat dissipation efficiency and energy-saving performance by optimizing the heat dissipation structure on the basis of traditional air-cooled chillers.

[0003] For example, a multi-finned heat exchanger air-cooled screw chiller unit disclosed in CN220489442U includes an air-cooled compartment with a chiller unit compartment at its bottom. Both sides of the chiller unit compartment have pads, and a cylinder is mounted on top of each pad. One end of the cylinder is connected to a rod, and the other end of the rod is connected to a clamping plate. A base plate is mounted on one side of the clamping plate, and two support frames are mounted on top of the base plate. The chiller unit is mounted on top of the two support frames. This invention, by using a cylinder, clamping plate, and support frames, and fixing the cylinder inside the air vent with pads, and by using the cylinder to push the rod, which then clamps the base plate, effectively improves the stability of the chiller unit's bottom mounting frame. The support frames fix the chiller unit to the base plate, thereby reducing vibration during operation, minimizing impact damage, and extending the chiller unit's service life.

Their ordinary finned structure has significant shortcomings in terms of expanding heat dissipation area and optimizing air disturbance, resulting in low heat dissipation efficiency. Key components inside the unit, such as compressors and condensers, are in high-temperature conditions for a long time. The high-temperature environment not only accelerates the aging of components and significantly shortens the overall service life of the equipment, but also makes the unit's energy consumption remain high, reducing the effectiveness of air-cooled chiller units.

This structure offers advantages in heat dissipation and energy saving, solving the problem of poor energy-saving performance commonly found in existing air-cooled chillers during actual operation. The conventional finned structure used in these chillers has significant shortcomings in terms of expanding the heat dissipation area and optimizing air turbulence, resulting in low heat dissipation efficiency. Key components inside the unit, such as the compressor and condenser, are subjected to high-temperature conditions for extended periods. This high-temperature environment not only accelerates component aging and significantly shortens the overall service life of the equipment but also leads to high energy consumption during unit operation, thus reducing the effectiveness of the air-cooled chiller.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving structure for an air-cooled chiller unit based on multi-stage fin heat dissipation, comprising an air-cooled chiller unit body and an air-cooled chamber, wherein the air-cooled chiller unit body is installed at the bottom of the air-cooled chamber, a unidirectional heat dissipation component is provided at the bottom of the air-cooled chamber, and an energy-saving ventilation component is provided at the top of the air-cooled chamber.

[0010] As a preferred embodiment of this utility model, a graphene block is installed on the top of the unidirectional heat conduction plate, and a plurality of graphene blocks are provided, which are arranged at equal intervals. The top of the graphene block is installed at the bottom of the wave-shaped heat dissipation fin.

[0011] As a preferred embodiment of this utility model, the top of the wave-shaped heat dissipation fins is provided with a lower air groove, and an exhaust pipe is installed at the bottom of the outer side of the wave-shaped heat dissipation fins. The outer side of the exhaust pipe is connected to the outer side of the inner wall of the air-cooled chamber.

[0014] As a preferred embodiment of this invention, the top of the wave-shaped heat dissipation fins is equipped with an air distribution inclined plate, and the wave-shaped heat dissipation fins are made of a high-entropy alloy.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model solves the problem of poor energy-saving performance of existing air-cooled chillers by setting up a unidirectional heat dissipation component in conjunction with an energy-saving ventilation component to achieve energy-saving heat dissipation of the air-cooled chiller body. The ordinary fin structure used in these chillers has obvious shortcomings in terms of expanding the heat dissipation area and optimizing air disturbance, which leads to low heat dissipation efficiency. Key components inside the unit, such as the compressor and condenser, are in high-temperature conditions for a long time. The high-temperature environment not only accelerates the aging of components and significantly shortens the overall service life of the equipment, but also makes the energy consumption of the unit high, thus reducing the performance of the air-cooled chiller and achieving the effect of heat dissipation and energy saving.

[0017] 2. This utility model, by setting up a unidirectional heat dissipation component, allows users to utilize the unidirectional heat conduction characteristics of the unidirectional heat conduction plate to prevent external heat from flowing back into the air-cooled chiller unit. This ensures that heat inside the unit can only be transferred in one direction, reducing unnecessary heat exchange and avoiding additional energy consumption caused by external heat backflow. The extremely high thermal conductivity of the graphene plate can quickly transfer heat to the unidirectional heat conduction plate, which is then accelerated by the graphene blocks to the wave-shaped heat dissipation fins, achieving efficient heat dissipation, reducing the internal temperature of the unit, and thus reducing the increased energy consumption of components such as the compressor due to high-temperature environments. This extends the service life of the equipment and achieves energy-saving goals.

[0018] 3. This utility model, by setting up energy-saving ventilation components, enables the low-speed, large-blade axial flow fan to achieve lower power consumption compared to traditional fans while providing the same air volume. The fan is installed in the mounting slot, and together with the ventilation slot and filter plate, it can accurately guide cold air in and hot air out. The filter plate prevents dust from entering, ensuring the cleanliness of the heat dissipation components, maintaining good heat exchange efficiency, and avoiding increased energy consumption due to dust accumulation affecting heat dissipation. This ensures that the air-cooled chiller unit operates stably in a low-energy-consumption state. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, the present invention provides an energy-saving structure for an air-cooled chiller unit based on multi-stage fin heat dissipation, including an air-cooled chiller unit body 1 and an air-cooled chamber 2. The air-cooled chiller unit body 1 is installed at the bottom of the air-cooled chamber 2. A one-way heat dissipation component 3 is provided at the bottom of the air-cooled chamber 2, and an energy-saving ventilation component 4 is provided at the top of the air-cooled chamber 2.

[0025] refer to Figure 3 The unidirectional heat dissipation component 3 includes a connecting groove 31, a unidirectional heat conduction plate 32 installed inside the connecting groove 31, a graphene plate 33 installed at the bottom of the unidirectional heat conduction plate 32, and a wave-shaped heat dissipation fin 34 provided at the top of the unidirectional heat conduction plate 32.

[0026] As a technical optimization of this utility model, by setting up a unidirectional heat dissipation component 3, users can utilize the unidirectional heat conduction characteristics of the unidirectional heat conduction plate 32 to prevent external heat from being reversed into the air-cooled chiller unit body 1, ensuring that the heat inside the unit can only be transferred out in one direction, reducing unnecessary heat exchange, and avoiding additional energy consumption of the unit due to external heat backflow. The extremely high thermal conductivity of the graphene plate 33 can quickly transfer heat to the unidirectional heat conduction plate 32, which is then accelerated by the graphene block 5 to the wave-shaped heat dissipation fins 34, achieving efficient heat dissipation, reducing the internal temperature of the unit, and thus reducing the energy consumption of components such as the compressor due to high-temperature environments, extending the service life of the equipment and achieving energy saving.

[0027] refer to Figure 2 The energy-saving ventilation component 4 includes an installation slot 41, in which a low-speed large-blade axial flow fan 42 is installed. A ventilation slot 43 is opened on the outside of the air-cooled chamber 2, and a filter plate 44 is installed inside the ventilation slot 43.

[0028] As a technical optimization of this utility model, by setting up an energy-saving ventilation component 4, the low-speed large-blade axial flow fan 42, compared with traditional fans, provides the same air volume, but with lower operating power consumption due to its lower speed and larger blades. The fan is installed in the mounting slot 41, and together with the ventilation slot 43 and filter plate 44, it can accurately guide cold air in and hot air out. The filter plate 44 prevents dust from entering, ensures the cleanliness of the heat dissipation components, maintains good heat exchange efficiency, avoids increased energy consumption due to dust accumulation affecting heat dissipation, and ensures stable operation of the air-cooled chiller unit 1 in a low-energy-consumption state.

[0029] refer to Figure 3 A graphene block 5 is installed on the top of the unidirectional heat conduction plate 32. Several graphene blocks 5 are arranged at equal intervals. The top of the graphene block 5 is installed at the bottom of the wave-shaped heat dissipation fin 34.

[0030] As a technical optimization of this utility model, by setting up graphene blocks 5, users can make use of their excellent thermal conductivity, which increases the thermal contact area between the unidirectional heat conduction plate 32 and the corrugated heat dissipation fins 34. Multiple graphene blocks 5 arranged at equal intervals make heat transfer more uniform and rapid, accelerate the heat dissipation speed, and enable the unit to reach a stable low-temperature operating state more quickly, thereby reducing the operating load of components such as the compressor and achieving energy saving.

[0031] refer to Figure 2 The top of the wave-shaped heat dissipation fin 34 is provided with a lower air slot 6, and an exhaust pipe 7 is installed at the bottom of the outer side of the wave-shaped heat dissipation fin 34. The outer side of the exhaust pipe 7 is connected to the outer side of the inner wall of the air-cooled chamber 2.

[0032] As a technical optimization of this utility model, by setting up a lower air duct 6 and an exhaust pipe 7, the lower air duct 6 delivers the air force transmitted by the air supply pipe 8 to the surface of the graphene block 5. The graphene block 5 has a high thermal conductivity and can quickly dissipate a certain amount of heat into the air, achieving initial rapid heat dissipation. The exhaust pipe 7 efficiently exhausts the hot air out of the air-cooled chamber 2, avoiding the accumulation of hot air in the chamber and affecting the heat dissipation effect. This optimizes the airflow path, reduces heat dissipation resistance, reduces the energy consumption required by the fan to exhaust the hot air, improves the overall heat dissipation efficiency, and indirectly achieves energy saving.

[0033] refer to Figure 2 The top of the lower air duct 6 is connected to an air supply pipe 8, and the other end of the air supply pipe 8 is connected to an air inlet ring 9.

[0034] As a technical optimization of this utility model, by setting up an air supply pipe 8 and an air inlet ring 9, the air inlet pipe can collect and transport a certain amount of air force delivered by the large-blade axial flow fan to the inside of the air inlet ring 9. The air inlet ring 9 collects external air and sends it to the lower air slot 6 through the air supply pipe 8, forming good convection with the hot air, accelerating heat exchange, so that the heat dissipation components are always in a high-efficiency heat dissipation environment, improving heat exchange efficiency, reducing the energy consumed by the unit to maintain the cooling effect, and achieving the purpose of energy saving.

[0035] refer to Figure 2 The low-speed large-blade axial flow fan 42 has a filter plate 10 installed at the inlet end, and a dust filter 11 is installed inside the exhaust pipe 7.

[0036] As a technical optimization of this utility model, by setting a filter plate 10 and a dust filter 11, the filter plate 10 is installed at the suction end of the low-speed large-blade axial flow fan 42, and the dust filter 11 is installed inside the exhaust pipe 7. The double protection avoids dust adhering to the heat dissipation components, ensuring the good heat dissipation performance of the heat dissipation components. Dust accumulation will increase thermal resistance and reduce heat dissipation efficiency, while keeping the heat dissipation components clean can effectively reduce the increase in energy consumption caused by poor heat dissipation, and ensure the long-term stable and energy-saving operation of the unit.

[0037] refer to Figure 2 The top of the wave-shaped heat dissipation fin 34 is equipped with an air distribution inclined plate 12, and the wave-shaped heat dissipation fin 34 is made of high entropy alloy.

[0038] As a technical optimization of this utility model, by setting the air distribution tilt plate 12, it is convenient for users to change the direction of airflow, so that the air is more evenly distributed on the surface of the wave-shaped heat dissipation fins 34. The air distribution tilt plate 12 is installed on the top of the wave-shaped heat dissipation fins 34, guiding the airflow to fully contact the heat dissipation fins, improving the heat exchange efficiency, so that the wind can quickly remove the heat dissipated inside the wave-shaped heat dissipation fins 34. More efficient heat exchange means that under the same cooling capacity requirement, the unit consumes less energy, thereby achieving energy saving.

[0039] The working principle and usage process of this utility model: When the air-cooled chiller unit 1 is running, it generates a large amount of heat. The entire energy-saving structure revolves around heat dissipation and air circulation. All components work together to achieve energy saving. The unidirectional heat conduction plate 32, with its unidirectional heat conduction characteristics, prevents external heat from being reversed into the air-cooled chiller unit 1, ensuring that heat inside the unit can only be transferred in one direction, avoiding unnecessary heat exchange and reducing the energy consumption required by the unit to maintain the cooling environment from the source. The graphene plate 33 at its bottom, utilizing its extremely high thermal conductivity, quickly absorbs the heat generated by the air-cooled chiller unit 1 and rapidly transfers it to the unidirectional heat conduction plate 32. The graphene blocks 5 evenly distributed at the top of the unidirectional heat conduction plate 32 further increase the thermal contact area with the corrugated heat dissipation fins 34, allowing heat to be conducted more evenly and efficiently to the corrugated heat dissipation fins 34. The corrugated heat dissipation fins 34 are made of high-entropy alloy material, which has excellent thermal conductivity and heat dissipation performance. The efficient heat dissipation process quickly dissipates heat into the surrounding air, reducing the internal temperature of the unit and minimizing the extra energy consumed by key components such as the compressor to overcome high-temperature environments, thus achieving energy savings. The low-speed, large-blade axial flow fan 42 plays a crucial role. Compared with traditional fans, the low-speed, large-blade axial flow fan 42 provides the same air volume but consumes less power due to its lower speed and larger blades. The fan is installed in the mounting slot 41, and its suction end filter plate 10 effectively filters dust and other impurities in the air, preventing these impurities from entering the air-cooled chamber 2. The filter plate 44 in the ventilation slot 43 filters the air again. This double filtration ensures that the air entering the air-cooled chamber 2 is clean, preventing dust from accumulating on the surface of the heat dissipation components, maintaining good heat exchange efficiency, and preventing increased energy consumption due to dust affecting heat dissipation. When the fan is running, it draws in external cold air into the air-cooled chamber 2. The cold air flows towards the wave-shaped heat dissipation fins 34 under the action of the fan, carrying away heat and achieving heat dissipation and cooling. The entire process is highly efficient with low energy consumption.

[0040] The lower air duct 6, exhaust duct 7, air supply duct 8, and air inlet ring 9 work together to optimize the airflow path, improve heat dissipation efficiency, and thus achieve energy saving. The lower air duct 6 guides the cold air transmitted by the air supply duct 8 to the surface of the graphene block 5, utilizing the high thermal conductivity of the graphene block 5 to achieve initial rapid heat dissipation. Subsequently, the lower air duct 6 guides the dissipated hot air to the exhaust duct 7, which efficiently exhausts the hot air out of the air-cooled chamber 2, preventing the hot air from accumulating inside the chamber, reducing heat dissipation resistance, and reducing the energy consumption required by the fan to exhaust the hot air. The air inlet ring 9 collects external air and sends the cold air to the lower air duct 6 through the air supply duct 8, forming good convection with the hot air, accelerating heat exchange, and ensuring that the heat dissipation components are always in a highly efficient heat dissipation environment. Efficient heat exchange means that under the same cooling capacity requirement, the unit does not need to consume too much energy to maintain the cooling effect, thereby achieving the purpose of energy saving.

[0041] The filter plate 10 is installed at the intake end of the low-speed large-blade axial flow fan 42, and the dust filter 11 is installed inside the exhaust pipe 7. Together, they form a double protection, which can effectively prevent dust, impurities and other contaminants from entering the air-cooled chamber 2 and avoid dust adhering to the heat dissipation components. Dust accumulation will increase thermal resistance and reduce heat dissipation efficiency, causing the unit to consume more energy to maintain the cooling effect. The filter plate 10 and the dust filter 11 ensure good heat dissipation performance of the heat dissipation components, reduce the increase in energy consumption caused by poor heat dissipation, and ensure long-term stable and energy-saving operation of the unit.

[0042] The air distribution tilt plate 12 is installed on the top of the corrugated heat dissipation fins 34. By changing the direction of airflow, the air is more evenly distributed on the surface of the corrugated heat dissipation fins 34, and the airflow is guided to fully contact the heat dissipation fins. In this way, the heat exchange efficiency is greatly improved, and the air can carry away the heat dissipated by the corrugated heat dissipation fins 34 more quickly. Under the same cooling capacity requirement, more efficient heat exchange means lower unit energy consumption, thereby achieving energy saving and heat dissipation energy saving effect, and enhancing the performance of the air-cooled chiller unit.

[0043] In summary, this energy-saving structure for an air-cooled chiller unit based on multi-stage finned heat dissipation, by setting up a unidirectional heat dissipation component 3 in conjunction with an energy-saving ventilation component 4 to dissipate heat from the air-cooled chiller unit body 1, solves the problem of poor energy-saving performance that is common in existing air-cooled chiller units during actual operation. The ordinary finned structure used in these units has significant shortcomings in terms of expanding the heat dissipation area and optimizing air disturbance, resulting in low heat dissipation efficiency. Key components inside the unit, such as the compressor and condenser, are subjected to high-temperature conditions for extended periods. This high-temperature environment not only accelerates component aging and significantly shortens the overall service life of the equipment, but also keeps the unit's energy consumption high, reducing the effectiveness of the air-cooled chiller unit.
