Description

Technical Field

[0001] This invention relates to the field of dual-system water-cooled machine technology, specifically to a dual-system water-cooled machine and its usage method. Background Technology

[0002] In fields such as precision manufacturing, laboratory equipment, and medical instruments, there are extremely high requirements for the temperature control of process coolants. Typically, the liquid needs to be kept stable in a low-temperature range close to zero degrees Celsius, and coolants of different temperatures need to be provided according to the specific process requirements of the client.

[0003] While existing technologies have attempted to employ dual-cycle systems, most have loose structures and inefficient thermal management between the refrigeration and liquid circuits, often failing to simultaneously achieve high-precision temperature control and efficient energy utilization. Therefore, there is an urgent need in this field for a dual-system water-cooled machine and its application method, capable of intelligently and adaptively adjusting the temperature output to client devices to ensure the required liquid temperature accuracy for the user. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-system water-cooled machine and its usage method to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a dual-system water-cooled machine and its usage method, comprising a water tank, a water receiving tray, a circulating water system one, and a circulating water system two. The circulating water system one includes a condensate pipe group and a water circulation pipe group. The water circulation pipe group includes a client device. One side of the client device is connected to a main outlet pipe two and an inlet pipe. One end of the main outlet pipe two is connected to a pre-adjustment three-way valve. The other two ends of the pre-adjustment three-way valve are respectively connected to a return pipe one and a main outlet pipe one. The inlet pipe and the return pipe one are connected. An anti-tipping electric ball valve is connected to the inlet pipe. A total flow sensor is connected to the return pipe one. A gate valve three, a conductivity sensor, and an outlet flow sensor are sequentially connected to the main outlet pipe two. One end of the return pipe one is located inside the water tank. A water pressure sensor, a water temperature control probe, an electric heating element, and a water pump are connected sequentially to the main outlet pipe. One end of the main outlet pipe is connected to the water tank. One end of the main outlet pipe is connected to the return pipe, and a differential pressure bypass valve is connected to the return pipe. A water level sensor is installed inside the water tank.

[0006] According to the above technical solution, the water tank is located inside the water receiving tray. An insulation layer is provided in the middle of the water tank, which divides the water tank into two different chambers, left and right. The two different chambers of the water tank are connected by a pipe. The circulating water system one and circulating water system two are located in the two different chambers of the water tank, respectively. A drain outlet is provided on one side of the water tank, and a valve is provided on the drain outlet. An overflow outlet is provided on one side of the top of the water tank.

[0007] According to the above technical solution, a vibrator is provided at the bottom of the two sets of chambers.

[0008] According to the above technical solution, the condensate pipe assembly includes a process cooling water system, inlet pipe one, inlet pipe two, outlet pipe one, and outlet pipe two. A coil is connected between inlet pipe two and outlet pipe two. The coil is installed inside the water tank. Inlet pipe one and outlet pipe one are connected to the process cooling water system. One end of inlet pipe one and outlet pipe one is connected to a high-efficiency tank. The other end of the high-efficiency tank is connected to inlet pipe two and outlet pipe two.

[0009] According to the above technical solution, a filter, a gate valve, and an inlet temperature probe are sequentially connected to the first inlet pipe from the process cooling water system to the high-efficiency tank, and a dryer filter and a capillary tube are sequentially connected to the second inlet pipe from the high-efficiency tank to the coil.

[0010] According to the above technical solution, a gate valve and an outlet temperature probe are sequentially connected to the first outlet pipe from the process cooling water system to the high-efficiency tank, and a compressor is connected to the first outlet pipe from the high-efficiency tank to the coil.

[0011] According to the above technical solution, the outlet pipe 2 and the inlet pipe 2 are connected by pipes, and the pipes of the outlet pipe 2 and the inlet pipe 2 are connected by solenoid valves.

[0012] According to the above technical solution, the method of using the dual-system water-cooled machine is as follows. Step 1: Start the condensate piping assembly to lower the temperature of the liquid in the water tank; Step 2: Start the circulating water system, adjust the temperature in the water tank to the user's desired temperature, and transmit the temperature to the client device.

[0013] According to the above technical solution, step two includes the following specific operational steps: Step 2-a: When the liquid passes through the main outlet pipe 1, it passes through the electric heating unit to heat the liquid on the main outlet pipe 1. When the liquid is heated to the temperature required by the customer, it enters the main outlet pipe 2 through the pre-adjusted three-way valve. Step 2-b: When the temperature does not meet the customer's equipment requirements, open the pre-adjustment three-way valve, close the main outlet pipe 2 channel, open the return pipe 2 channel, and return the unmet liquid back to the water tank. Step 2-c: Detect water pressure using a water pressure sensor. When the detected water pressure is greater than the preset hydraulic pressure, open the differential pressure bypass valve to release the liquid from the main outlet pipe 1 into the return pipe 2, and then into the water tank, ensuring normal output hydraulic pressure.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: This invention, by incorporating a circulating water system, can adaptively regulate the temperature of the discharged liquid, ensuring that the user's operating temperature meets requirements and further improving the accuracy of the liquid temperature required by the user.

[0015] By incorporating a vibrator and an overflow port, liquid from one chamber is transferred to another, increasing the liquid level in that chamber until it reaches the overflow port. Simultaneously, the liquid flows from the overflow port into a receiving tray. The vibrator is activated at the same time, causing the liquid in that chamber to vibrate and mix, preventing impurities from settling in the liquid and allowing impurities to be discharged more effectively from the drain port. This avoids the problem of impurities being difficult to remove when changing the liquid in a chamber. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5 The present invention provides a technical solution: a dual-system water-cooled machine, including a water tank 1, a water receiving tray 4, a circulating water system 5 and a circulating water system 6. The water tank 1 is located inside the water receiving tray 4. An insulation layer 3 is provided in the middle of the interior of the water tank 1. The insulation layer 3 divides the water tank 1 into two different chambers, left and right. The two different chambers of the water tank 1 are connected by a pipe. The circulating water system 5 and the circulating water system 6 are located in the two different chambers of the water tank 1, respectively. A drain outlet 40 is provided on one side of the water tank 1. A valve is provided on the drain outlet 40. An overflow outlet 41 is provided on one side of the top of the water tank 1.

[0019] Vibrators (not shown in the figure) are installed at the bottom of the two sets of chambers.

[0020] The circulating water system 5 includes a condensate piping group and a water circulation piping group. The condensate piping group includes a process cooling water system 36, inlet pipe 35, inlet pipe 31, outlet pipe 30, and outlet pipe 32. A coil 11 is connected between inlet pipe 31 and outlet pipe 32, and the coil 11 is located inside the water tank 1. Inlet pipe 35 and outlet pipe 30 are connected to the process cooling water system 36. One end of inlet pipe 35 and outlet pipe 30 is connected to a high-efficiency tank 7, and the other end of the high-efficiency tank 7 is connected to inlet pipe 31 and outlet pipe 32. Through inlet pipe 35, inlet pipe 31, outlet pipe 30, outlet pipe 32, and high-efficiency tank 7, the coil 11 and the process cooling water system 36 form a loop.

[0021] On inlet pipe 1 35, from the process cooling water system 36 to the high-efficiency tank 7, a filter 17, a gate valve 16 and an inlet temperature probe 14 are connected in sequence. On inlet pipe 2 31, from the high-efficiency tank 7 to the coil 11, a dryer filter 8 and a capillary tube 9 are connected in sequence.

[0022] A gate valve 37 and an outlet temperature probe 15 are sequentially connected on the outlet pipe 30 from the process cooling water system 36 to the high-efficiency tank 7. A compressor 10 is connected on the outlet pipe 30 from the high-efficiency tank 7 to the coil 11.

[0023] The outlet pipe 32 and the inlet pipe 31 are connected by a pipeline, and a solenoid valve 13 is connected to the pipeline of the outlet pipe 32 and the inlet pipe 31.

[0024] It should be noted that the process cooling water system 36 is existing technology and will not be discussed in detail here.

[0025] Coil 11 is placed in water tank 1, replacing the plate type as a chiller. When compressor 10 is started, the refrigerant in outlet pipe 2 32 is pumped into high-efficiency tank 7, and then enters inlet pipe 2 31 to form a loop with coil 11. Since the coolant in process cooling water system 36 flows back to process cooling water system 36 through inlet pipe 1 35, through high-efficiency tank 7, and then through outlet pipe 1 30, the refrigerant in outlet pipe 2 32 passes through high-efficiency tank 7 and can cool down the high-temperature refrigerant generated by compressor 10 through the cold temperature in high-efficiency tank 7. When the refrigerant passes through dryer filter 8 and then enters capillary tube 9, it is further cooled down through capillary tube 9. The refrigerant passing through coil 11 cools down the liquid in water tank 1, controlling the temperature in water tank 1 at 0.1 degrees Celsius.

[0026] It should be noted that when the refrigerant temperature is still too low, the solenoid valve 13 is opened, allowing the refrigerant to pass directly through the solenoid valve 13 and then enter the outlet pipe 32 for circulation.

[0027] The water circulation pipeline assembly includes client equipment 2. One side of client equipment 2 is connected to main outlet pipe 2 38 and inlet pipe 39. One end of main outlet pipe 2 38 is connected to pre-adjustment three-way valve 23. The other two ends of pre-adjustment three-way valve 23 are respectively connected to return pipe 1 29 and main outlet pipe 1 33. Inlet pipe 39 and return pipe 1 29 are connected to each other. Anti-tipping electric ball valve 26 is connected to inlet pipe 39. Total flow sensor 27 is connected to return pipe 1 29. Gate valve 3 25, conductivity sensor 28 and outlet flow sensor 24 are connected in sequence to main outlet pipe 2 38. One end of return pipe 1 29 is located inside water tank 1.

[0028] A water pressure sensor 22, a water temperature control probe 21, an electric heating group 19, and a water pump 18 are connected sequentially to the main outlet pipe 33. One end of the main outlet pipe 33 is connected to the water tank 1.

[0029] One end of the main outlet pipe 33 is connected to the return pipe 34, and the return pipe 34 is connected to the differential pressure bypass valve 20.

[0030] Water level sensor 12 is installed inside water tank 1. The water level sensor 12 detects the liquid level in water tank 1. When the liquid level in water tank 1 is lower than the set liquid level, the anti-backflow electric ball valve is opened, and the liquid from client device 2 is transferred to return pipe 29 through inlet pipe 39. The total flow sensor 27 detects the flow rate of liquid entering water tank 1 and controls the flow rate of liquid entering water tank 1 within a suitable range.

[0031] Example 1 When the liquid temperature inside water tank 1 decreases, water pump 18 is activated to pump the liquid from water tank 1 through main outlet pipe 33 into pre-adjusting three-way valve 23. As the liquid passes through main outlet pipe 33, it passes through the electric heating unit, which heats the liquid on main outlet pipe 33. When the liquid reaches the customer's required temperature, it passes through pre-adjusting three-way valve 23 into main outlet pipe 38, and then into customer-end equipment 2 for customer use. When the temperature does not meet the customer's equipment requirements, pre-adjusting three-way valve 23 is opened, the channel of main outlet pipe 38 is closed, and the channel of return pipe 34 is opened, returning the unmet liquid to water tank 1. This process adaptively adjusts the liquid temperature, ensuring that the user's operating temperature meets requirements and further improving the accuracy of the liquid temperature required by the user.

[0032] When the liquid passes through the water flow sensor 24 on the main outlet pipe 38, the liquid flow rate is detected in real time, so that the outgoing liquid flow rate is within a suitable range.

[0033] When the liquid passes through the main outlet pipe 33, the water pressure is detected by the water pressure sensor 22. When the detected water pressure is greater than the preset hydraulic pressure, the differential pressure bypass valve 20 is opened to release the liquid from the main outlet pipe 33 into the return pipe 34, and then into the water tank 1, ensuring that the output hydraulic pressure is normal.

[0034] To further explain, the structure of the second circulating water system 6 is the same as that of the first circulating water system 5. The difference is that the second circulating water system 6 is equipped with two or more sets of electric heating groups. The first circulating water system 5 is used for a 1.5KW circulating water system, and the second circulating water system 6 is used for a 6.5KW circulating water system. The two are used together to achieve energy saving, and the two are set in the same equipment to reduce the floor space.

[0035] Example 2 When the water level sensor 12 detects that the liquid level in the water tank 1 is lower than the normal value, the anti-tipping electric ball valve 26 is opened to allow the liquid to flow back into the water tank 1. During the backflow process, the total flow sensor 27 detects the flow rate entering the water tank 1 in real time and records the total liquid flow rate entering the water tank 1 as L, ensuring that the liquid in the water tank 1 is always at the normal level.

[0036] When the water level sensor 12 detects that the liquid level is higher than the set normal value, it opens the valve on the drain outlet 40 to discharge the excess liquid in the water tank 1 into the water receiving tray 4.

[0037] During this process, the total liquid flow rate L remains constant, and when the outflow sensor 24 detects that the outflow rate is constant, while the water level is always higher than the set normal liquid level value (under normal circumstances, the liquid level in the chamber of water tank 1 will always be at the set normal value), but lower than the overflow port 41, it indicates that the drain port 40 is not easy to drain, proving that there are impurities in the liquid in water tank 1, and the water in water tank 1 needs to be replaced.

[0038] Specifically, since the water tank 1 has two different chambers, when one of the chambers has impurities and needs to be replaced, the liquid from the other chamber can be transferred through a pipe to the chamber with more impurities to dilute the liquid in the chamber with more impurities, while the other chamber continues to be supplied with liquid, always ensuring that the liquid level in the other chamber is at the set value.

[0039] Meanwhile, the liquid in the chamber with more impurities continues to be fed into another chamber, increasing the amount of liquid in that chamber until the liquid level is level with the overflow port 41. The liquid then flows out from the overflow port 41 into the water receiving tray 4. Simultaneously, the vibrator is activated, causing the liquid in that chamber to vibrate and mix, preventing impurities from settling in the liquid and better discharging the liquid with impurities from the drain port 40. This avoids the situation where impurities are difficult to discharge when changing the liquid in the chamber.

[0040] By following the steps above, the circulating water system can continue to operate normally and ensure work efficiency when replacing liquids in multi-chambered chambers containing impurities.

[0041] A method for using a dual-system water-cooled machine includes the following operating steps: Step 1: Start the condensate piping assembly to lower the temperature of the liquid in water tank 1.

[0042] Step 2: Start the circulating water system, adjust the temperature in water tank 1 to the user's desired temperature, and transmit the temperature to the client device.

[0043] Step two includes the following specific operational steps: Step 2-a: When the liquid passes through the main outlet pipe 1 33, it passes through the electric heating unit, which heats the liquid on the main outlet pipe 1 33. When the liquid is heated to the temperature required by the customer, it enters the main outlet pipe 2 38 through the pre-adjusting three-way valve 23. Step 2-b: When the temperature does not meet the customer's equipment requirements, open the pre-adjustment three-way valve 23, close the main outlet pipe 2 38, open the return pipe 2 34, and return the unmet liquid back to the water tank 1. Step 2-c: The water pressure is detected by the water pressure sensor 22. When the detected water pressure is greater than the preset hydraulic pressure, the differential pressure bypass valve 20 is opened to release the liquid from the main outlet pipe 33 into the return pipe 34, and then into the water tank 1, ensuring that the output hydraulic pressure is normal.
