Description

Technical Field

[0001] This utility model relates to the field of cooling equipment design technology, specifically to a water-oil integrated cooling machine. Background Technology

[0002] Water chillers and oil chillers are liquid cooling devices that can provide constant temperature, constant flow, and constant pressure. Traditional equipment can only cool a single liquid medium. If different liquids need to be cooled simultaneously, separate water chiller units and oil chiller units are required, resulting in low integration. Utility Model Content

[0003] In view of this, the present invention provides an integrated water-oil cooling machine to solve the problem of low integration of existing cooling equipment.

[0004] This utility model provides an integrated water-oil cooling machine, comprising: A water tank having an inlet pipe and an outlet pipe, wherein the outlet pipe is connected to one end of a water pump; A heat exchanger has an inlet and an outlet, the inlet being connected to the other end of a water pump, and the heat exchanger being connected to a refrigeration device, suitable for exchanging heat between the water supplied by the water pump and the refrigerant in the refrigeration device. The three-way valve has its inlet connected to the outlet of the heat exchanger, its first outlet connected to the water tank, and its second outlet being the cooling water outlet. An oil pump has an oil inlet pipe at one end and an oil outlet pipe at the other end. The body of the oil inlet pipe is located inside the water tank and is suitable for heat exchange with the water in the water tank. The controller is communicatively connected to the water pump and the oil pump.

[0005] In this application, the integrated water-oil cooling unit integrates the water tank, heat exchanger, three-way valve, oil pump, and controller into a single cooling system architecture, enabling simultaneous water and oil cooling. This application integrates the traditionally independent water and oil cooling systems into a single unit, reducing equipment footprint and external piping complexity. Through coordinated control of the water and oil pumps by the controller, the system can dynamically adjust its operating status according to actual cooling needs. For example, when only water cooling is required, the oil pump can be shut off, and all cooling power can be allocated to the water circulation system, avoiding energy waste. The three-way valve enables oil cooling. Water from the inlet pipe and the heat exchanger outlet flows into the three-way valve. The first outlet connects to the water tank, cooling the water in the tank for subsequent cooling of the oil inlet pipe. The second outlet directly discharges cooling water.

[0006] In one optional embodiment, the oil inlet pipe is coiled.

[0007] In this application, the oil inlet pipe is designed as a coil structure, which expands the heat exchange interface between the oil passage and the water in the water tank. The coil shape improves heat transfer efficiency by extending the fluid path and increasing the effective heat transfer area per unit volume.

[0008] In one alternative embodiment, the oil inlet pipe is spirally wound inside the water tank in both the inner and outer directions.

[0009] In this application, the oil inlet pipe is arranged in a double-spiral coil within the water tank, optimizing the flow channel structure and flow characteristics based on a single coil. The double-spiral design creates parallel and isolated flow channels, dispersing the oil flow rate, reducing flow resistance and system pressure drop along a single path, and ensuring more uniform oil distribution within the water tank volume. This avoids the formation of localized heat exchange dead zones, ensuring efficient utilization of the overall cooling capacity of the water in the tank. Furthermore, the double-spiral structure increases the uniformity of contact between the oil inlet pipe and water, enlarging the cooling area and ensuring sufficient and consistent cooling of the oil in different flow channels, thus guaranteeing the stability of the oil outlet temperature.

[0010] In one optional embodiment, the refrigeration device includes: A compressor, suitable for compressing the refrigerant inside it, has an inlet and an outlet, the inlet being connected to the liquid outlet of a heat exchanger, and the compressor being communicatively connected to a controller; The radiator is tubular, with one end connected to the compressor outlet and the other end connected to the heat exchanger inlet.

[0011] In this application, the compressor, acting as the system power source, compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure state, creating the necessary conditions for subsequent condensation and heat release. The radiator transfers the heat absorbed by the refrigerant from the cooled medium to the external environment. This application allows a single refrigeration circuit to simultaneously serve both water cooling and oil cooling needs. The water circuit is directly cooled via a heat exchanger, and the oil circuit is indirectly cooled via the cooled water, achieving intelligent allocation and efficient utilization of refrigeration power. Compared to traditional independent units, this centralized refrigeration solution reduces the number of mechanical components, lowers system complexity, and improves the overall energy efficiency ratio through unified management.

[0012] In one optional embodiment, a fan is provided on one side of the radiator to facilitate heat dissipation, and the radiator is communicatively connected to the controller.

[0013] In this application, the fan enhances the heat exchange efficiency between the radiator and the surrounding air through forced convection, ensuring that the refrigerant can quickly release heat during condensation. The controller adjusts the fan based on real-time system operating parameters such as condensing pressure or ambient temperature, enabling the system to adapt to different environmental conditions. Under low ambient temperatures, the controller can reduce the fan speed or completely shut down the fan to maintain appropriate condensing pressure and temperature, thus optimizing adaptability and reliability under different seasons and climatic conditions.

[0014] In one alternative implementation, the water inlet pipe is connected to the top of the water tank.

[0015] In one alternative embodiment, the water outlet pipe is connected to the bottom of the water tank.

[0016] In this application, the inlet pipe is connected to the top of the water tank and the outlet pipe is connected to the bottom of the water tank, forming a natural convection circulation structure that conforms to thermodynamic principles. High-temperature return water enters from the top of the water tank and, due to its lower density, naturally rises and distributes in the upper layer of the tank, while the lower-temperature cooling water, due to its higher density, naturally settles to the bottom of the tank. This temperature stratification phenomenon promotes the spontaneous circulation of water within the tank and optimizes the heat distribution.

[0017] In one optional embodiment, a temperature sensor is installed inside the water tank and is communicatively connected to the controller. The controller can be set to a preset temperature. When the user does not need to use cooling oil, the oil pump can be turned off. At this time, the three-way valve provides some water back to the water tank, lowering the temperature of the water in the tank. When the temperature reaches the preset temperature, the controller can stop the compressor from running, thus reducing power consumption even when only water cooling is used.

[0018] In one alternative implementation, the water tank is also connected to an overflow pipe.

[0019] In this application, the overflow pipe can serve as a safe channel for pressure balancing and liquid overflow, providing a reliable pressure relief and drainage path. It can also guide excess liquid to a safe area in the event of an overfilling failure in the water system, preventing internal leakage or damage to electrical components.

[0020] In one alternative implementation, it further includes: The housing, including the water tank, heat exchanger, refrigeration equipment, three-way valve, and oil pump, is located inside the housing. One side of the housing is the air inlet, and the top is the air outlet. The radiator is located at the air outlet, and the fan is located at the top of the housing.

[0021] In this application, by integrating all functional components inside the housing, the equipment can be miniaturized and integrated. One side of the housing is designated as the air inlet and the top as the air outlet. This, in conjunction with the arrangement of the internal radiator and fan, forms an upward airflow channel. This utilizes the physical property of hot air rising naturally, reducing the energy consumption of the fan and preventing hot air from circulating and accumulating inside the equipment.

[0022] In one optional embodiment, one side of the housing has openings that respectively cooperate with the water inlet pipe, water outlet pipe, oil inlet pipe, oil outlet pipe and overflow pipe.

[0023] In this application, the opening on one side of the housing provides a connection point for the water-oil cooling integrated unit to connect with the water circuit, oil circuit, and safety pipeline of the external system, simplifying the on-site installation process. With all pipe interfaces concentrated on a single side, the water-oil cooling integrated unit only requires operating space on one side during installation, reducing the space requirements for the installation environment.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0028] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0029] According to an embodiment of this utility model, a water-oil cooling integrated machine is provided, such as... Figure 2 As shown, it includes: Water tank 1 has an inlet pipe 2 and an outlet pipe 3, wherein the outlet pipe 3 is connected to one end of water pump 4; The heat exchanger 5 has an inlet and an outlet. The inlet is connected to the other end of the water pump 4. The heat exchanger 5 is connected to a refrigeration device and is suitable for exchanging heat between the water supplied by the water pump 4 and the refrigerant in the refrigeration device. The heat exchanger 5 includes an inlet, an outlet, a liquid inlet, and a liquid outlet. Internally, the heat exchanger 5 has a first pipe connecting the inlet and outlet, and a second pipe connecting the liquid inlet and outlet. The two pipes can exchange heat. The water tank 1 is connected to the first pipe, and the refrigeration device is connected to the second pipe. The heat exchanger 5 can be a plate heat exchanger.

[0030] The three-way valve 6 has its inlet connected to the outlet of the heat exchanger 5, its first outlet connected to the water tank 1 via the connecting pipe 20, and its second outlet is the cooling water outlet, which is connected to the outlet pipe 21.

[0031] Oil pump 7, one end is connected to oil inlet pipe 8 and the other end is connected to oil outlet pipe 9. The body of oil inlet pipe 8 is located inside water tank 1 and is suitable for heat exchange with water in water tank 1. The controller is communicatively connected to the water pump 4 and the oil pump 7.

[0032] In this application, the integrated water-oil cooling unit integrates the water tank 1, heat exchanger 5, three-way valve 6, oil pump 7, and controller into a cooling system architecture, enabling simultaneous water and oil cooling. This application integrates the traditionally independent water and oil cooling systems into a single unit, reducing equipment footprint and external piping complexity. Through coordinated control of the water pump 4 and oil pump 7 by the controller, the system can dynamically adjust its operating status according to actual cooling needs. For example, when only water cooling is required, the oil pump 7 can be shut down, and all cooling power can be allocated to the water circulation system, avoiding energy waste. The three-way valve 6 enables oil cooling. Water from the inlet pipe 2 and the outlet of the heat exchanger 5 flow into the three-way valve 6. The first outlet connects to the water tank 1, cooling the water in the tank, which can then be used to cool the oil in the oil inlet pipe 8. The second outlet directly discharges cooling water.

[0033] In one alternative implementation, such as Figure 3 As shown, the oil inlet pipe 8 has a coiled shape.

[0034] In this application, the oil inlet pipe 8 is designed as a coil structure, which expands the heat exchange interface between the oil passage and the water in the water tank 1. The coil shape improves heat transfer efficiency by extending the fluid path and increasing the effective heat transfer area per unit volume.

[0035] In one alternative implementation, such as Figure 3 As shown, the body of the oil inlet pipe 8 is spirally wound inside the water tank 1 in both the inner and outer directions. Specifically, the body of the oil inlet pipe 8 consists of two spirally wound pipes, which are respectively connected to the ends of the oil inlet pipe 8. One of the two spirally wound pipes is located on the inner side in a spiral shape, and the other is located on the outer side in a spiral shape.

[0036] In this application, the oil inlet pipe 8 is arranged in a double-spiral coil within the water tank 1, optimizing the flow channel structure and flow characteristics based on a single coil. The double-spiral design forms parallel and isolated flow channels, dispersing the oil flow rate, reducing flow resistance and system pressure drop along a single path, and ensuring more uniform oil distribution within the water tank 1 volume. This avoids the formation of localized heat exchange dead zones, ensuring efficient utilization of the cooling capacity of the entire water tank 1. The double-spiral structure also increases the uniformity of contact between the oil inlet pipe 8 and the water, increasing the cooling area and ensuring sufficient and consistent cooling of the oil in different flow channels, thus guaranteeing the stability of the oil outlet temperature.

[0037] In one alternative implementation, such as Figure 2 As shown, the refrigeration equipment includes: The compressor 11 is adapted to compress the refrigerant inside it, and has an inlet and an outlet. The inlet can be connected to the liquid outlet of the heat exchanger 5 through a pipe. The compressor 11 is communicatively connected to the controller. The radiator 12 is tubular, with one end connected to the outlet of the compressor 11 and the other end connected to the liquid inlet of the heat exchanger 5. The radiator 12 can be a reciprocating wound pipe.

[0038] In this application, the compressor 11 serves as the system power source, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure state, creating the necessary conditions for subsequent condensation and heat release. The radiator 12 transfers the heat absorbed by the refrigerant from the cooled medium to the external environment. This application allows a single refrigeration circuit to simultaneously serve both water cooling and oil cooling needs. The water circuit is directly cooled by the heat exchanger 5, and the oil circuit is indirectly cooled by the cooled water, achieving intelligent allocation and efficient utilization of refrigeration power. Compared to traditional independent units, the centralized refrigeration solution in this application reduces the number of mechanical parts, lowers system complexity, and improves the overall energy efficiency ratio through unified management.

[0039] In one optional embodiment, a fan 13 is provided on one side of the radiator 12 to dissipate heat from the radiator 12, and the radiator 12 is communicatively connected to the controller.

[0040] In this application, the fan 13 enhances the heat exchange efficiency between the radiator 12 and the surrounding air through forced convection, ensuring that the refrigerant can quickly release heat during condensation. The controller adjusts the fan 13 based on real-time system operating parameters such as condensing pressure or ambient temperature, enabling the system to adapt to different environmental conditions. Under low ambient temperatures, the controller can reduce the fan 13 speed or completely shut it down to maintain appropriate condensing pressure and temperature, thus optimizing adaptability and reliability under different seasons and climatic conditions.

[0041] In one alternative embodiment, the water inlet pipe 2 is connected to the top of the water tank 1.

[0042] In one alternative embodiment, the water outlet pipe 3 is connected to the bottom of the water tank 1.

[0043] In this application, two inlet pipes are connected to the top of water tank 1, and three outlet pipes are connected to the bottom of water tank 1, forming a natural convection circulation structure that conforms to thermodynamic principles. High-temperature return water enters from the top of water tank 1 and, due to its lower density, naturally rises and distributes in the upper layer of water tank 1, while the lower-temperature cooling water, due to its higher density, naturally settles to the bottom of water tank 1. This temperature stratification phenomenon promotes the spontaneous circulation of water inside water tank 1 and optimizes the heat distribution.

[0044] In one optional embodiment, a temperature sensor is installed in the water tank 1 and is communicatively connected to the controller. The controller can set a preset temperature. When the user does not need to use cooling oil, the oil pump 7 can be turned off. At this time, the three-way valve 6 provides some water back to the water tank 1, which lowers the temperature of the water in the water tank 1. When the temperature reaches the preset temperature, the controller can stop the operation of the compressor 11, which can also reduce power consumption when only water cooling is used.

[0045] In one alternative embodiment, the water tank 1 is also connected to an overflow pipe 14.

[0046] In this application, the overflow pipe 14 can serve as a safe channel for pressure balancing and liquid overflow, providing a reliable pressure relief and drainage path. It can also guide excess liquid to a safe area in the event of an overfilling failure in the water system, preventing internal leakage or damage to electrical components.

[0047] In one alternative implementation, such as Figure 1 As shown, it also includes: The housing 15, the water tank 1, heat exchanger 5, refrigeration equipment, three-way valve 6 and oil pump 7 are all located inside the housing 15. One side of the housing 15 is the air inlet surface 16 and the top surface is the air outlet surface 17. The radiator 12 is located at the air outlet surface 17 and the fan 13 is located at the top of the housing 15.

[0048] Specifically, the air inlet surface 16 and the air outlet surface 17 of the housing 15 are connected. Under the action of the fan 13, air can reach the air outlet surface 17 through the air inlet surface 16. The housing 15 can be two-layered. The water tank 1, heat exchanger 5, refrigeration equipment, and three-way valve 6 can be located in the lower layer, the oil pump 7 can be located in the upper layer, and the controller can also be located in the lower layer. The radiator 12 can be located at the inner top of the housing 15, opposite to the fan 13. The air inlet surface 16 can be a grille structure.

[0049] In this application, by integrating all functional components inside the housing 15, the device can be miniaturized and integrated. One side of the housing 15 is designated as the air inlet surface 16 and the top surface as the air outlet surface 17. This, in conjunction with the arrangement of the internal radiator 12 and fan 13, forms an upward airflow channel. This utilizes the physical property of hot air rising naturally, reducing the energy consumption of the fan 13 and preventing hot air from circulating and accumulating inside the device.

[0050] In one optional embodiment, one side of the tank 15 has openings 18 that respectively mate with the water inlet pipe 2, water outlet pipe 3, oil inlet pipe 8, oil outlet pipe 9, and overflow pipe 14. The tank 15 may also include openings 18 adapted to the outlet pipe 21. A drain pipe 19 may be connected to the bottom of the water tank 1, and openings 18 matching the drain pipe 19 may be provided on the tank 15.

[0051] In this application, the opening 18 provided on one side of the housing 15 provides a connection point for the water-oil cooling integrated unit to connect with the water circuit, oil circuit and safety pipeline of the external system, simplifying the on-site installation process. With all pipe interfaces concentrated on a single side, the water-oil cooling integrated unit only requires operating space on one side during installation, reducing the space requirements for the installation environment.

[0052] In this application, high-temperature water flows from the inlet pipe 2 into the water tank 1 inside the housing 15. The water pump 4 draws water from the water tank 1 and flows through the inlet into the heat exchanger 5 to exchange heat with the refrigerant. After heat exchange, the water in the heat exchanger 5 exits through the outlet as cooling water, and then flows through the second outlet of the three-way valve 6 into the heating device to cool it, thus completing one water cooling cycle. When oil cooling is required, the oil pump 7 starts and draws high-temperature oil into the body of the oil inlet pipe 8 inside the water tank 1 through the oil inlet pipe 8. The body of the oil inlet pipe 8 is a double-spiral coil inside and outside the water tank 1, making large-area contact with the water in the water tank 1. During water cooling cycle, the cooling water flowing out of the heat exchanger 5 enters the water tank 1 through the first outlet of the three-way valve 6 and exchanges heat with the body of the oil inlet pipe 8. After the oil in the body of the oil inlet pipe 8 is cooled, it is discharged through the oil outlet pipe 9 and flows into the heating device for cooling, thus completing one oil cooling cycle.

[0053] In the gas path section, the compressor 11 compresses the refrigerant into a high-temperature, high-pressure gas and sends it to the radiator 12 for cooling through the outlet. Driven by the fan 13, the air flows through the radiator 12, carrying away the heat released by the refrigerant. The high-temperature, high-pressure gaseous refrigerant becomes a low-temperature liquid refrigerant and flows out of the radiator 12. Then it flows into the inlet of the heat exchanger 5 to exchange heat with the high-temperature water, turning the high-temperature water into low-temperature water. After that, the refrigerant flows back from the gas path outlet of the heat exchanger 5 to the inlet of the compressor 11, thus completing one gas path cycle.

[0054] Existing cooling systems require two separate systems: one oil cooler for the spindle and one water cooler for the motor. This is complex, space-consuming, and costly. This application proposes an integrated oil-water cooling system. The water cooler is designed with a total cooling capacity of 10kW, with 5kW each for oil and water cooling. The oil cooling system can operate independently. When the user does not need the cooling oil, the oil pump 7 can be turned off. At this time, the three-way valve 6 returns some water to the water tank 1, lowering the water temperature. When the temperature reaches the preset temperature, the controller can stop the compressor 11, reducing power consumption even when only water cooling is used. The controller can regulate the pressure and the start / stop of the fan 13, allowing the system to operate normally in low-temperature environments by turning off the fan 13 to increase the condensing temperature. It is designed for year-round operation.
