Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a circulating water cooling evaporator. Background Art

[0002] Circulating cooling water is pumped from the water tank to the spray tube bundle, which continuously and evenly sprays the cooling water onto the heat exchange tubes (or cooling coils). The cooling water exchanges heat with the process fluid (such as steam or high-temperature, high-pressure gas / liquid) within the heat exchange tubes through the tube walls. The process fluid releases heat, which the cooling water absorbs, raising its temperature and causing some of the cooling water to evaporate, forming water vapor. The majority of the unevaporated cooling water flows downward into the water tank, where it is pumped back to the spray tube bundle, completing the cooling water cycle.

[0003] A search revealed that patent publication number CN201520388269.1 discloses a plastic-steel profile circulating water cooling system. While the system ensures water pressure and flow in the chiller's evaporator during the cooling cycle, and provides good heat dissipation for the chiller's condenser, reducing the chiller's energy consumption and saving costs, the system only controls the heat exchange rate by adjusting the flow rate. This results in a short heat exchange time for the medium and low heat exchange efficiency. Due to this short heat exchange time, the cooling water may not be able to fully absorb heat, resulting in poor cooling performance. To compensate for this lack of heat exchange efficiency, it is necessary to increase the cooling water flow rate or extend the cooling time, which increases energy consumption. Low heat exchange efficiency can lead to decreased production efficiency, which in turn increases production costs. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a circulating water cooling evaporator, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A circulating water cooling evaporator comprises a first buffer tank, the bottom end of the first buffer tank is connected to a second heat exchange tank and the first heat exchange tank, and the second heat exchange tank and the first heat exchange tank are connected through the second buffer tank;

[0007] The second heat exchange tank and the first heat exchange tank are provided with heat exchange tubes, and second flanges are provided at both ends of the heat exchange tubes. The second heat exchange tank and the first heat exchange tank are respectively provided with a liquid outlet and a liquid inlet at one end away from the second buffer tank, and the liquid outlet and the liquid inlet are both provided with a first flange, and the second heat exchange tank and the first heat exchange tank are also provided with a first flange at both ends. The second heat exchange tank and the first heat exchange tank are fixed to the second flanges of the heat exchange tubes by cooperating with the first flanges of the liquid outlet and the liquid inlet through the first flange;

[0008] The upper surfaces of the second heat exchange tank and the first heat exchange tank are provided with upper joints, and the lower surfaces of the second heat exchange tank and the first heat exchange tank are provided with lower joints. The second heat exchange tank and the first heat exchange tank are respectively connected to the liquid outlet pipe and the liquid inlet pipe through the upper joints, and the second heat exchange tank and the first heat exchange tank are connected to the first cache tank through the liquid outlet pipe and the liquid inlet pipe.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a pressure-stabilizing tube is provided at the top of the first cache tank, and the first cache tank exchanges air through the pressure-stabilizing tube, thereby maintaining the pressure in the first cache tank stable.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The pressure regulator allows air to exchange between the first buffer tank and the outside world, effectively regulating and maintaining a stable pressure within the tank. By maintaining a stable pressure, the pressure regulator helps optimize the efficiency of the cooling evaporation system. Stable pressure conditions help ensure smooth flow of the medium within the system, thereby improving heat exchange efficiency and overall system performance.

[0013] Furthermore, a joint is provided at the bottom end of the first cache tank, and the liquid inlet pipe and the liquid outlet pipe are connected to the first cache tank via the joint.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] This design allows the inlet and outlet pipes to connect directly to the bottom of the first buffer tank via joints, eliminating the need for additional connectors or piping. This not only simplifies the system structure but also reduces potential leak points, improving overall system reliability and stability. Joint design typically takes into account the flow characteristics of the medium to ensure smooth flow through the pipes. This helps reduce resistance and energy consumption in the system, improving the system's heat exchange efficiency.

[0016] Furthermore, the second heat exchange tank and the first heat exchange tank are symmetrically distributed at both ends of the second cache tank.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The symmetrical distribution design also helps enhance system stability. Because the two heat exchange tanks are identical in structure and function, they complement and balance each other, reducing the impact of a single tank failure or performance degradation on the entire system. This design improves system redundancy and reliability. The symmetrical distribution design simplifies and facilitates installation and maintenance. Since the two heat exchange tanks share the same structure, installers can more easily determine their installation location and connection method, reducing installation time and costs. Similarly, during maintenance, since the disassembly and inspection procedures for both heat exchange tanks are identical, maintenance personnel can complete the work more quickly, improving efficiency.

[0019] Furthermore, the high-temperature medium enters the first heat exchange tank through the lower joint at the bottom end of the first heat exchange tank, and enters the first cache tank from the upper joint and the liquid inlet pipe at the top end of the first heat exchange tank, and then enters the upper joint of the second heat exchange tank from the liquid outlet pipe at the bottom end of the first cache tank, and then flows out of the second heat exchange tank from the lower joint at the bottom end of the second heat exchange tank.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] After entering the heat exchange tank through the lower connector, the high-temperature medium directly heats the low-temperature medium flowing through the heat exchange tubes. This design ensures sufficient contact and efficient heat exchange between the high-temperature and low-temperature media, thereby improving the heat exchange efficiency of the entire system. The flow path within the heat exchange tank is rationally designed, avoiding problems such as poor flow and dead spots. The high-temperature medium enters through the lower connector, is heated by the heat exchange tubes, and then flows out through the upper connector. It then passes through the buffer tank and enters the next heat exchange tank. The entire flow process is smooth and unobstructed, reducing energy consumption and resistance. Because the high-temperature and low-temperature media undergo sufficient heat exchange within the heat exchange tank, the system temperature distribution is more uniform, thereby enhancing system stability. This stability helps reduce system failures or performance degradation caused by temperature fluctuations. Through efficient heat exchange and smooth medium flow, this circulating water cooling evaporator achieves more efficient energy utilization, reducing energy consumption and emissions. This helps reduce operating costs while complying with environmental and sustainable development requirements.

[0022] Furthermore, a timing valve is connected to the lower joint at the bottom end of the second heat exchange tank, and the high-temperature medium in the second heat exchange tank is discharged from the second heat exchange tank through the timing valve.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The timing valve ensures that the high-temperature medium in the second heat exchange tank is discharged at the appropriate time, preventing excessive accumulation or retention of the medium within the tank. This helps maintain the fluidity and heat exchange efficiency of the medium within the heat exchange tank, ensuring continuous and efficient system operation. By regularly discharging the high-temperature medium, the circulation and reuse of the medium within the system can be more effectively managed. This helps reduce medium waste and loss, while improving medium utilization and overall system performance. The precise control of the timing valve helps maintain stable pressure and temperature of the medium within the system. By regularly discharging the high-temperature medium, pressure increases or temperature fluctuations caused by medium accumulation can be prevented, thereby enhancing system stability and reliability.

[0025] The utility model provides a circulating water cooling evaporator. It has the following beneficial effects:

[0026] By installing heat exchange tubes within the first and second heat exchange tanks and securely securing both ends of the tubes to the tanks with flanges, this design ensures efficient and stable heat exchange. The high-temperature medium flowing through the heat exchange tubes effectively transfers heat to the surrounding low-temperature medium, achieving efficient heat exchange.

[0027] This evaporator, through pipe connections and valve control, enables flexible medium flow. High-temperature medium can enter from the bottom of the first heat exchange tank. After heat exchange, it flows through the upper connector and liquid inlet pipe into the first buffer tank. From the first buffer tank, it flows through the liquid outlet pipe into the second heat exchange tank for further heat exchange, and finally exits from the bottom of the second heat exchange tank. This design not only improves heat exchange efficiency but also increases system flexibility and controllability.

[0028] The pressure-stabilizing tube at the top of the first buffer tank allows the system to maintain stable internal pressure through air exchange. This is crucial for maintaining normal system operation and extending the life of the equipment. The timed valve at the bottom of the second heat exchange tank allows the system to regularly discharge high-temperature media, preventing overheating and scaling that can occur if the media remains in the tank for extended periods. This design not only improves system reliability and stability but also facilitates equipment maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 3 As shown, the embodiment provided by the utility model:

[0038] Example 1

[0039] A circulating water cooling evaporator includes a first cache tank 1, the bottom end of the first cache tank 1 is connected to a second heat exchange tank 2 and a first heat exchange tank 4, the second heat exchange tank 2 and the first heat exchange tank 4 are connected through a second cache tank 3, and the second heat exchange tank 2 and the first heat exchange tank 4 are symmetrically distributed at both ends of the second cache tank 3. The symmetrical distribution design strategy enhances the stability of the system. The consistency of the structure and function of the two heat exchange tanks enables them to complement and balance each other, effectively reducing the impact of failure or performance degradation of a single heat exchange tank on the entire system. This design improves the redundancy and reliability of the system while simplifying the installation and maintenance process. Because the two heat exchange tanks have the same structure, installers can quickly determine their installation location and connection method, shortening installation time and reducing costs. In terms of maintenance, the disassembly and inspection processes of the two heat exchange tanks are consistent, which improves maintenance efficiency. Heat exchange tubes 406 are provided in the second heat exchange tank 2 and the first heat exchange tank 4, and second flanges 405 are provided at both ends of the heat exchange tube 406. The second heat exchange tank 2 and the first heat exchange tank 4 are respectively provided with a liquid outlet 201 and a liquid inlet 402 at the end facing away from the second buffer tank 3, and the liquid outlet 201 and the liquid inlet 402 are both provided with a first flange 404, and the second heat exchange tank 2 and the first heat exchange tank 4 are also provided with a first flange 404 at both ends. The second heat exchange tank 2 and the first heat exchange tank 4 cooperate with each other through the first flange 404 and the first flange 404 of the liquid outlet 201 and the liquid inlet 402 to clamp and fix the second flange 405 of the heat exchange tube 406.

[0040] Example 2

[0041] In order to increase the heat exchange efficiency, for example, Figures 1 to 3As shown, the present invention also includes: an upper joint 403 is provided on the upper surface of the second heat exchange tank 2 and the first heat exchange tank 4, and a lower joint 202 is provided on the lower surface of the second heat exchange tank 2 and the first heat exchange tank 4. A timing valve is connected to the lower joint 202 at the bottom end of the second heat exchange tank 2, and the high-temperature medium in the second heat exchange tank 2 is discharged from the second heat exchange tank 2 through the timing valve. The setting of the timing valve ensures that the high-temperature medium in the second heat exchange tank 2 is discharged in time at the predetermined time, avoiding excessive accumulation or retention of the medium in the tank. This mechanism helps to maintain the fluidity and heat exchange efficiency of the medium in the heat exchange tank, ensuring the continuous and efficient operation of the system. By regularly discharging the high-temperature medium, the effective circulation and reuse of the medium in the system is achieved, the waste and loss of the medium are reduced, and the utilization rate of the medium and the overall performance of the system are improved. Precise control of the timing valve helps maintain the pressure and temperature stability of the system's internal media, preventing pressure increases or temperature fluctuations caused by media accumulation, thereby enhancing the system's stability and reliability. The second heat exchange tank 2 and the first heat exchange tank 4 are connected to the liquid outlet pipe 104 and the liquid inlet pipe 101, respectively, via the upper joint 403. The bottom end of the first cache tank 1 is provided with a joint 103, through which the liquid inlet pipe 101 and the liquid outlet pipe 104 communicate with the first cache tank 1. The liquid inlet pipe 101 and the liquid outlet pipe 104 are directly connected to the bottom end of the first cache tank 1 via the joint 103, without the need for additional connectors or piping. This design not only simplifies the system structure and reduces potential leakage risks, but also significantly improves the system's reliability and stability. The design of joint 103 fully considers the flow characteristics of the medium, ensuring smooth flow of the medium within the pipeline, effectively reducing system resistance and energy consumption, and improving heat exchange efficiency. The second heat exchange tank 2 and the first heat exchange tank 4 are connected to the first buffer tank 1 through the liquid outlet pipe 104 and the liquid inlet pipe 101. The high-temperature medium enters the first heat exchange tank 4 through the lower joint 202 at the bottom of the first heat exchange tank 4, and enters the first buffer tank 1 through the upper joint 403 and the liquid inlet pipe 101 at the top of the first heat exchange tank 4. It then enters the upper joint 403 of the second heat exchange tank 2 from the liquid outlet pipe 104 at the bottom of the first buffer tank 1, and then flows out of the second heat exchange tank 2 through the lower joint 202 at the bottom of the second heat exchange tank 2. After entering the heat exchange tank through the lower joint 202, the high-temperature medium directly heats the low-temperature medium flowing in the heat exchange tube 406. This design ensures sufficient contact between the high-temperature medium and the low-temperature medium, achieves efficient heat exchange, and improves the overall heat exchange efficiency of the system. The flow path within the heat exchange tank is rationally designed, avoiding problems such as poor flow and dead corners. High-temperature medium enters through lower connector 202, is heated by heat exchange tube 406, and then flows out of upper connector 403. It then passes through the buffer tank and enters the next heat exchange tank. The entire flow process is smooth and unobstructed, reducing energy consumption and resistance.Because the high-temperature and low-temperature media undergo sufficient heat exchange within the heat exchange tank, the system temperature distribution becomes more uniform, enhancing system stability and reducing system failures or performance degradation caused by temperature fluctuations. A pressure-stabilizing tube 102 is installed at the top of the first buffer tank 1. The first buffer tank 1 exchanges air through the pressure-stabilizing tube 102, thereby maintaining a stable pressure within the first buffer tank 1. The design of the pressure-stabilizing tube 102 allows the first buffer tank 1 to exchange air with the external environment, thereby precisely regulating and maintaining the pressure within the tank at a stable state. This mechanism helps optimize the overall operating efficiency of the cooling evaporation system, ensuring smooth and unimpeded flow of media within the system, thereby improving heat exchange efficiency and overall system performance.

[0042] Working principle:

[0043] The high-temperature medium is introduced into the bottom joint 202 of the first heat exchange tank 4. A closed circulation system is formed between the first buffer tank 1, the second heat exchange tank 2 and the first heat exchange tank 4 through connectors such as pipes and flanges.

[0044] High-temperature medium enters the bottom of the first heat exchange tank 4 and exchanges heat with the low-temperature medium through heat exchange tube 406. After heat exchange, the high-temperature medium flows into the first buffer tank 1 through upper connector 403 and liquid inlet pipe 101. The medium then flows into the second heat exchange tank 2 through liquid outlet pipe 104 for further heat exchange. Finally, the medium is discharged from the bottom connector 202 of the second heat exchange tank 2, completing one cycle. A timed valve at the bottom of the second heat exchange tank 2 opens periodically to remove high-temperature medium or accumulated waste liquid from the system, maintaining cleanliness and efficient operation.

[0045] Heat exchange tube 406 is a key component within the first and second heat exchange tanks 4 and 2. It allows the low-temperature medium to flow through the tube and exchange heat with the high-temperature medium outside the tube. Both ends of heat exchange tube 406 are fixed to the tanks via flanges, ensuring the stability and reliability of the heat exchange process.

[0046] As the low-temperature medium flows through heat exchange tubes 406, it absorbs heat from the high-temperature medium outside the tubes. As the low-temperature medium absorbs heat, its temperature rises, and some of it evaporates, forming water vapor (depending on the properties and temperature of the low-temperature medium). The heat exchange process continues until the high-temperature medium's temperature drops to a predetermined value or the low-temperature medium reaches saturation.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
