Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to a refrigeration energy-saving device. Background Technology

[0002] Existing cooling systems for PCB drilling machines suffer from numerous problems, the most prominent being excessive energy consumption. Firstly, traditional cooling systems are inefficient, with poorly designed coolant circulation paths leading to uneven coolant distribution. Some areas are over-cooled while others are under-cooled, impacting drilling accuracy and equipment lifespan while increasing energy consumption. Secondly, components like water pumps and cooling fans in existing systems operate inefficiently and cannot be precisely controlled according to actual needs, often operating at high energy consumption, even under low loads. Furthermore, the cooling system lacks effective monitoring and regulation functions, failing to monitor key parameters such as coolant flow and temperature in real time, hindering dynamic energy-saving operation. These problems collectively contribute to energy waste in PCB drilling machine cooling systems, increasing production costs and imposing unnecessary environmental burdens. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a refrigeration energy-saving device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a refrigeration energy-saving device, comprising: The support frame includes an upper frame and a lower frame arranged sequentially along a first direction. Both the upper and lower frames extend along a second direction. A water tank is located inside the lower frame. A condenser is located inside the upper frame for cooling the coolant.

[0005] A heat exchange device includes a plate heat exchanger and a drive assembly. The plate heat exchangers are located on both sides of the condenser along a third direction. Each plate heat exchanger includes a liquid channel and a heat exchange channel. The liquid channel is connected to the water tank piping, and the heat exchange channel is connected to the condenser piping. The drive assembly is located on one side of the water tank along a second direction and is used to drive the coolant cooled by the condenser and the water in the water tank to flow sequentially through the plate heat exchanger for heat exchange.

[0006] This utility model provides a refrigeration energy-saving device that employs a plate heat exchanger, which boasts a large heat exchange area and high heat exchange efficiency. Coolant and water can fully exchange heat within the plate heat exchanger, allowing the water to absorb the heat from the coolant, thereby reducing the cooling demand of the coolant and lowering the energy consumption of the refrigeration system. The structural characteristics of the plate heat exchanger enable it to maintain stable heat exchange performance over a wide range of flow rates and pressures. A stable temperature difference is maintained between the coolant and water during the heat exchange process, ensuring stable operation of the refrigeration system. The drive assembly ensures stable flow of coolant and water, preventing reduced heat exchange efficiency or system malfunctions due to poor fluid flow. Furthermore, the drive assembly utilizes advanced control technology to automatically adjust the fluid flow rate and pressure according to system requirements, further improving system operational stability. The layered support frame structure and integrated heat exchanger design ensure relatively fixed positions for each component, facilitating inspection and maintenance. Maintenance personnel can quickly locate faulty components and perform replacement or repair, reducing maintenance time and costs.

[0007] In some embodiments, the plate heat exchanger includes a liquid inlet, a liquid outlet, a cooling inlet, and a cooling outlet. The liquid inlet and the liquid outlet are spaced apart along a first direction, the cooling outlet and the cooling inlet are spaced apart along the first direction, and the liquid inlet and the cooling inlet are spaced apart along a third direction. The cooling outlet is connected to the inlet pipe of the condenser, and the liquid outlet is connected to the water tank pipe, for inputting the cooled liquid after heat exchange into the condenser for further cooling, and for re-inputting the cooled water into the water tank.

[0008] Using the above technical solution, the coolant after heat exchange returns directly to the condenser through the outlet for further cooling. This design ensures full utilization of the coolant's heat, reduces coolant temperature fluctuations, and improves the condenser's cooling efficiency. The cooled water returns to the water tank through the cooling outlet, achieving water recycling. This design not only saves water resources but also reduces water temperature fluctuations, improving system stability. Compared to single-use water or simple circulation methods, this design better maintains the water tank's temperature balance and reduces additional cooling requirements.

[0009] In some embodiments, the drive assembly includes a water pump and a storage tank. The inlet of the water pump is connected to the water tank pipeline, and the outlet is connected to the liquid inlet pipeline. The liquid inlet of the storage tank is located near the top and is connected to the outlet pipeline of the condenser, while the liquid outlet is located near the bottom and is connected to the cooling inlet pipeline, for storing and discharging cooled coolant.

[0010] Using the above technical solution, the storage tank can store a certain amount of coolant, acting as a buffer. The inlet end of the storage tank is near the top and connects to the outlet pipe of the condenser, while the outlet end is near the bottom and connects to the cooling inlet pipe. This design ensures sufficient settling and separation of the coolant within the storage tank, allowing the coolant to enter the cooling inlet in a stable state. This prevents a gas-liquid mixture from directly entering the cooling system, improving the efficiency and stability of the cooling system.

[0011] In some embodiments, both the inlet and outlet ends of the water pump are provided with connecting flanges.

[0012] Using the above technical solution, the flange connection is achieved through bolts and gaskets, providing a reliable seal and effectively preventing fluid leakage. Under high pressure or high flow conditions, the sealing performance of the flange connection is particularly critical, significantly reducing energy waste and system failure risks caused by leakage. When pump maintenance or replacement is required, the detachability of the flange connection makes operation more convenient. Maintenance personnel can easily remove the flange to inspect, clean, or replace the pump without requiring extensive disassembly and reinstallation of the entire piping system.

[0013] In some embodiments, the condenser is a V-shaped condenser, comprising two condensing plates arranged at opposite inclinations and a plurality of cooling fans. The condensing plates have an inlet and an outlet at one end along the first direction near the plate heat exchanger. The plurality of cooling fans are spaced apart at the top of the upper frame along the second direction.

[0014] Using the above technical solution, the two condensing plates of the V-shaped condenser are arranged at an angle towards each other. This structure can significantly increase the heat exchange area of ​​the condenser. Compared with traditional flat plate condensers, the V-shaped condenser can provide more heat exchange surface, thereby improving the cooling efficiency of the coolant. The cooling fans are spaced apart at the top of the upper frame along the second direction. This layout ensures that the cold air flows evenly across the surface of the condensing plates. The V-shaped structure causes the airflow to form vortices between the condensing plates, further enhancing the heat exchange effect and improving the cooling efficiency.

[0015] In some embodiments, the water tank has a plurality of solenoid valves at the end away from the water pump along the second direction. These solenoid valves are spaced apart along the second direction and are all connected to the water tank's piping, serving as the water tank's outlet. The water tank has an inlet at the end closer to the water pump along the second direction for replenishing water into the tank.

[0016] By employing the above technical solution, the rapid response characteristics of the solenoid valves enable the system to dynamically adjust the water flow rate according to real-time requirements. Multiple solenoid valves are spaced apart along the second direction, and this multi-point water outlet design allows for precise control of the water flow rate. By independently controlling the opening and closing of each solenoid valve, the water flow rate and direction can be flexibly adjusted according to system needs, ensuring uniform distribution and efficient utilization of water within the system.

[0017] In some embodiments, the upper frame is provided with a control panel at one end away from the plate heat exchanger along the first direction. The control panel includes multiple display instruments and meters for displaying the operating status of the solenoid valve, water pump, and liquid storage tank.

[0018] Using the above technical solution, the displays and meters on the control panel can show the real-time operating status of the solenoid valves, water pumps, and storage tanks, including key parameters such as flow rate, pressure, and temperature. The real-time monitoring function allows operators to promptly detect abnormalities in the system, such as solenoid valve malfunctions, water pump abnormalities, or insufficient liquid levels in the storage tank. By diagnosing and addressing these problems in a timely manner, system failures can be reduced, and the stability and reliability of the system can be improved.

[0019] In some embodiments, the support frame further includes multiple fixed sheet metal parts, which are respectively located at the corners of the upper frame and the lower frame.

[0020] Using the above technical solutions, corners are typically areas of structural stress concentration, which can easily lead to material fatigue and damage. Fixing sheet metal at the corners of the frame significantly enhances the overall rigidity of the support structure and disperses stress. When bearing the weight of the equipment and vibrations generated during operation, this enhanced rigidity reduces frame deformation and swaying, thereby improving the stability of the entire device.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] refer to Figure 1 and Figure 2 , Figure 1 This invention illustrates a three-dimensional view of a refrigeration energy-saving device 1 provided in an embodiment of the present invention. Figure 1 . Figure 2 This invention illustrates a three-dimensional view of a refrigeration energy-saving device 1 provided in an embodiment of the present invention. Figure 2 .

[0024] like Figure 1 and Figure 2 As shown, the technical solution provided in this application is a refrigeration energy-saving device 1, comprising: Support frame 2, including along the first direction ( Figure 1 The upper frame 20 and the lower frame 21 are arranged sequentially in the Z direction (as shown in the middle Z direction). Both the upper frame 20 and the lower frame 21 are along the second direction ( Figure 1 Extending in the X direction, the lower frame 21 houses a water tank 50. The upper frame 20 houses a condenser 40 for cooling the coolant.

[0025] The heat exchange device includes a plate heat exchanger 30 and a drive assembly. The plate heat exchanger 30 is located on the condenser 40 along a third direction ( Figure 1 On both sides (as shown in the Y direction), the plate heat exchanger 30 includes a liquid channel and a heat exchange channel. The liquid channel is connected to the water tank 50 via piping, and the heat exchange channel is connected to the condenser 40 via piping. A drive assembly is located on one side of the water tank 50 along the second direction, used to drive the coolant cooled by the condenser 40 and the water in the water tank 50 to flow sequentially through the plate heat exchanger 30 for heat exchange. The first direction, the second direction, and the third direction are perpendicular to each other.

[0026] The energy-saving refrigeration device 1 provided in this application employs a plate heat exchanger 30, which has a large heat exchange area and high heat exchange efficiency. Coolant and water can fully exchange heat in the plate heat exchanger 30, allowing the water to absorb the heat from the coolant, thereby reducing the cooling demand of the coolant and lowering the energy consumption of the refrigeration system. The structural characteristics of the plate heat exchanger 30 enable it to maintain stable heat exchange performance over a wide range of flow rates and pressures. A stable temperature difference is maintained between the coolant and water during the heat exchange process, ensuring stable operation of the refrigeration system. The drive assembly ensures stable flow of coolant and water, preventing reduced heat exchange efficiency or system failure due to poor fluid flow. Simultaneously, the drive assembly can employ advanced control technology to automatically adjust the fluid flow rate and pressure according to system requirements, further improving system operational stability. The layered support frame 2 structure and integrated heat exchanger design ensure relatively fixed positions for each component, facilitating inspection and maintenance. Maintenance personnel can quickly locate faulty components and replace or repair them, reducing maintenance time and costs.

[0027] In some embodiments, reference Figure 1 and Figure 2 The plate heat exchanger 30 includes an inlet 31, an outlet 32, a cooling inlet 33, and a cooling outlet 34. The inlet 31 and outlet 32 ​​are spaced apart along a first direction, and the cooling outlet 34 and cooling inlet 33 are spaced apart along the first direction. The inlet 31 and cooling inlet 33 are spaced apart along a third direction. The cooling outlet 34 is connected to the inlet pipe of the condenser 40, and the outlet 32 ​​is connected to the water tank 50. These connections are used to input the cooled liquid after heat exchange into the condenser 40 for further cooling, and to re-input the cooled water into the water tank 50.

[0028] For example, the coolant after heat exchange returns directly to the condenser 40 through the outlet 32 ​​for further cooling. This design ensures full utilization of the coolant's heat, reduces temperature fluctuations, and improves the cooling efficiency of the condenser 40. The cooled water returns to the water tank 50 through the cooling outlet 34, achieving water recycling. This design not only saves water resources but also reduces water temperature fluctuations, improving system stability. Compared to single-use water or simple circulation methods, this design better maintains the temperature balance of the water tank 50, reducing additional cooling requirements.

[0029] In some embodiments, reference Figure 1 and Figure 2The drive assembly includes a water pump 35 and a storage tank 36. The inlet end of the water pump 35 is connected to the water tank 50 via a pipeline, and the outlet end is connected to the liquid inlet 31 via a pipeline. The liquid inlet end of the storage tank 36 is located near the top and is connected to the outlet pipeline of the condenser 40, while the liquid outlet end is located near the bottom and is connected to the cooling inlet 33 via a pipeline, for storing and discharging cooled coolant.

[0030] For example, the liquid storage tank 36 can store a certain amount of coolant, acting as a buffer. The inlet end of the liquid storage tank 36 is near the top and connected to the outlet pipe of the condenser 40, while the outlet end is near the bottom and connected to the cooling inlet 33. This design ensures sufficient settling and separation of the coolant within the liquid storage tank 36, allowing the coolant to enter the cooling inlet 33 in a stable state, preventing the direct entry of a gas-liquid mixture into the cooling system, and improving the efficiency and stability of the cooling system. The water pump 35 can precisely control the water flow rate according to the system's needs, ensuring that the flow velocity and flow rate of the water in the plate heat exchanger 30 meet the heat exchange requirements. The efficient drive of the water pump 35 and the buffering effect of the liquid storage tank 36 can reduce the energy consumption of coolant and water circulation in the system. By optimizing the fluid flow path and flow control, the system can achieve efficient heat exchange with lower energy consumption, thereby reducing the overall energy consumption of the refrigeration system.

[0031] In some embodiments, reference Figure 1 and Figure 2 The water pump 35 is equipped with connecting flanges 37 at both the inlet and outlet ends.

[0032] For example, the flange 37 is connected via bolts and a gasket, providing a reliable seal and effectively preventing fluid leakage. The sealing performance of the flange connection is particularly critical under high pressure or high flow conditions, significantly reducing energy waste and system failure risks caused by leakage. The removability of the flange connection facilitates maintenance or replacement of the pump 35. Maintenance personnel can easily remove the flange to inspect, clean, or replace the pump 35 without requiring extensive disassembly and reinstallation of the entire piping system.

[0033] In some embodiments, reference Figure 1 and Figure 2 The condenser 40 is a V-shaped condenser 40, including two condensing plates 41 arranged at opposite inclinations and multiple cooling fans 42. The condensing plates 41 have an inlet and an outlet at one end near the plate heat exchanger 30 along a first direction. The multiple cooling fans 42 are spaced apart at the top of the upper frame 20 along a second direction.

[0034] For example, the two condensing plates 41 of the V-shaped condenser 40 are inclined towards each other, a structure that significantly increases the heat exchange area of ​​the condenser 40. Compared to a conventional flat-plate condenser 40, the V-shaped condenser 40 provides more heat exchange surface, thereby improving the cooling efficiency of the coolant. Cooling fans 42 are spaced apart at the top of the upper frame 20 along a second direction, ensuring that cool air flows evenly across the surface of the condensing plates 41. The V-shaped structure causes the airflow to form vortices between the condensing plates 41, further enhancing the heat exchange effect and improving cooling efficiency.

[0035] In some embodiments, reference Figure 1 and Figure 2 The water tank 50 is equipped with multiple solenoid valves 51 at the end away from the water pump 35 along the second direction. The multiple solenoid valves 51 are spaced apart along the second direction and are all connected to the pipeline of the water tank 50, serving as the outlet of the water tank 50. The water tank 50 is equipped with an inlet 52 at the end closer to the water pump 35 along the second direction, for replenishing water into the water tank 50.

[0036] For example, the rapid response of the solenoid valve 51 enables the system to dynamically adjust the water flow rate according to real-time demand. Multiple solenoid valves 51 are spaced apart along the second direction, and this multi-point outlet design allows for precise control of the water flow rate. By independently controlling the opening and closing of each solenoid valve 51, the water flow rate and direction can be flexibly adjusted according to system requirements, ensuring uniform distribution and efficient utilization of water within the system.

[0037] In some embodiments, reference Figure 1 and Figure 2 The upper frame 20 is provided with a control panel 23 at one end away from the plate heat exchanger 30 along the first direction. The control panel 23 includes multiple display instruments and meters for displaying the working status of the solenoid valve 51, the water pump 35 and the liquid storage tank 36.

[0038] For example, the displays and meters on the control panel 23 can show the real-time operating status of the solenoid valve 51, water pump 35, and liquid storage tank 36, including key parameters such as flow rate, pressure, and temperature. This real-time monitoring function allows operators to promptly detect abnormalities in the system, such as solenoid valve 51 malfunction, water pump 35 malfunction, or insufficient liquid level in the liquid storage tank 36. By diagnosing and addressing these issues promptly, system failures can be reduced, and the stability and reliability of the system can be improved.

[0039] In some embodiments, reference Figure 1 and Figure 2 The support frame 2 also includes multiple fixed sheet metal parts 22, which are respectively located at the corners of the upper frame 20 and the lower frame 21.

[0040] For example, corners are typically areas of structural stress concentration, which can easily lead to material fatigue and damage. The fixed sheet metal 22, installed at the corners of the frame, significantly enhances the overall rigidity of the support frame 2 and disperses stress. This enhanced rigidity reduces frame deformation and swaying when subjected to the weight of the equipment and vibrations generated during operation, thereby improving the stability of the entire device.
