Description

Technical Field

[0001] This utility model relates to the field of heat exchanger equipment technology, specifically to a multifunctional titanium tube heat exchanger. Background Technology

[0002] Titanium tube heat exchangers are heat exchange devices made of high-quality titanium tubes that transfer part of the heat from a hot fluid to a cold fluid. Because titanium tubes have strong corrosion resistance, do not easily form an oxide layer on their surface, do not pollute the medium, are environmentally friendly and non-toxic, and can avoid failures caused by seawater corrosion, titanium tube heat exchangers have been widely used in water-source equipment such as swimming pools, seafood processing machines, and aquaculture machines.

[0003] However, existing titanium tube heat exchangers still have certain drawbacks, such as the inability to achieve effective water flow monitoring. We know that heat exchange utilizes the temperature difference between two fluids to exchange heat. A common example is refrigerant flowing through the heat exchange coils and water flowing through the heat exchanger shell. This requires continuous flow between these two fluids to achieve the desired heat exchange effect. However, if a water pump malfunctions or a pipe blockage interrupts the water flow while the compressor continues to run, it may lead to heat exchange failure. The refrigerant's heat cannot be carried away by the water flow, resulting in no heat exchange effect and potentially causing compressor overload or damage. Furthermore, it may cause localized overheating of the titanium tubes, ultimately leading to damage due to thermal stress deformation, resulting in significant economic losses. Utility Model Content

Detailed Implementation

[0023] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0024] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] refer to Figure 1-5This utility model provides a multifunctional titanium tube heat exchanger, which is mainly a vertical titanium tube heat exchanger, suitable for heat exchange of water sources such as swimming pools, seafood machines or aquaculture machines. It includes a shell 1 and a heat exchange coil 2. A cavity 10 is formed inside the shell 1 to accommodate the heat exchange coil 2. The heat exchange coil 2 has a medium inlet pipe 20 and a medium outlet pipe 21. The medium inlet pipe 20 and the medium outlet pipe 21 are connected. The medium flows from the medium inlet pipe 20 to the medium outlet pipe 21. At least a portion of the medium inlet pipe 20 and the medium outlet pipe 21 extends out of the cavity 10 to facilitate the input and output of the medium from the outside (the medium may be a refrigerant or a heat medium). A water inlet pipe 11 and a water outlet pipe 12 are provided on the shell 1 and communicate with the cavity 10. The water inlet pipe 11 and the water outlet pipe 12 are respectively spaced apart along the height direction of the shell 1. In this embodiment, the water inlet pipe 11 is located at the bottom of the shell 1 and the water outlet pipe 12 is located at the top of the shell 1 (of course, it can also be arranged in reverse, which is not limited in this application). A first detection component 3 is provided on the shell 1. The first detection component 3 is located near the water outlet pipe 12 and is used to detect the water outlet status of the water outlet pipe 12.

[0027] Specifically, in this embodiment, the first detection component 3 is mainly located at the connection between the cavity 10 and the outlet pipe 12, and is situated within the cavity 10. This ensures that the first detection component 3 can promptly detect the water flow status from the cavity 10 to the outlet pipe 12 (i.e., the water outlet status of the outlet pipe 12). The water flow status refers to the state where water can flow towards the outlet pipe 12. Once the first detection component 3 detects that no water flows out of the outlet pipe 12, it indicates that water circulation cannot be formed. At this time, the compressor is controlled to stop operating to prevent heat exchange from failing, thereby avoiding excessive pressure or temperature inside the heat exchanger, which could damage the heat exchanger. Additionally, it also prevents the heat exchanger from malfunctioning due to poor water flow, thus effectively preventing energy waste and improving the operating efficiency of the equipment.

[0028] refer to Figure 2-4In a preferred embodiment, the first detection component 3 includes a first sensor (not shown, such as a magnetic sensor) and a movable member 30. The movable member 30 is oscillatingly disposed within the housing 1 and located near the water outlet pipe 12. Under the action of water flow, the movable member 30 can oscillate along the flow direction of the water flow. The first sensor is configured to detect a sensing signal when the movable member 30 stops oscillating. In this embodiment, the first sensor can be a magnetic sensor. The movable part 30 is provided with a magnetic material. The water flows from the inlet pipe 11 to the outlet pipe 12. When the water flows continuously towards the outlet pipe 12, the movable part 30 can swing in the direction of the water flow under the pressure or impact of the water flow. The swinging of the movable part 30 also means that the magnetic field is constantly changing. Once the water circulation is disrupted, that is, the water cannot flow out of the outlet pipe 12, the movable part 30 remains stationary when the pressure or impact is lost. At this time, the magnetic field remains unchanged. The first sensor can detect this signal and control the compressor (or other components) to stop operating through the controller to prevent the heat exchanger from failing to exchange heat and causing the temperature inside the heat exchanger to become too high, which would damage the heat exchanger.

[0029] refer to Figure 2-4 In a preferred embodiment, the first detection component 3 further includes a mounting head 31, which is detachably connected to the housing 1. In this embodiment, the mounting head 31 and the housing 1 are connected by a threaded connection, making disassembly and assembly more convenient. The first sensor is fixed to the mounting head 31 and connected to the movable part 30 (the connection between the first sensor and the movable part 30 can be a physical connection or a non-contact connection). The housing 1 is provided with a mounting port, which communicates with the cavity 10. The mounting head 31 can drive the movable part 30 to extend or extend into the housing 1 through the mounting port. When the mounting head 31 is connected to the housing 1, the mounting port can be closed. That is to say, in this embodiment, the first sensor and the movable part 30 are integrated into the mounting head 31. During installation, the movable part 30 is first inserted into the housing 1 through the mounting head 31, and then the mounting head 31 is screwed tightly onto the housing 1. If the movable part 30 or the first sensor is damaged, the parts can be replaced by removing the mounting head 31, resulting in lower maintenance costs.

[0030] refer to Figure 4 In a preferred embodiment, the movable component 30 includes a connecting rod 301 and a flow-receiving plate 302. One end of the connecting rod 301 is fixed to the mounting head 31, and the other end is connected to the flow-receiving plate 302. The radial dimension of the flow-receiving plate 302 is larger than the radial dimension of the connecting rod 301, and the plate surface of the flow-receiving plate 302 is perpendicular to the direction of water flow.

[0031] In this embodiment, the guide vane 302, as the component primarily in contact with the water flow, has a radial dimension larger than that of the connecting rod 301, thereby enabling the guide vane 302 to have a larger surface area. For example, if the connecting rod 301 is cylindrical, then the radial dimension of the connecting rod 301 can be understood as the diameter of the cylinder; if the guide vane 302 is rectangular, then the radial dimension of the guide vane 302 can be understood as the width of the guide vane 302. Simultaneously, the surface of the guide vane 302 (the side impacted by the water flow) is perpendicular to the direction of water flow, maximizing its ability to withstand the impact of the water flow and better sensing the pressure and impact force of the water flow, thus effectively generating an oscillation under the action of the water flow. When the water flows normally, the moving part 30 will swing under the impact of the water flow, and the magnetic field is in dynamic change. When there is a problem with the water circulation, such as when the water cannot flow out of the outlet pipe 12, the moving part 30 will stop swinging due to the loss of water pressure and impact force. At this time, the magnetic field also remains unchanged. The first sensor can detect this stable state of the magnetic field, thereby triggering subsequent control actions, such as controlling the compressor to stop operating, to prevent the heat exchanger from being damaged due to poor heat exchange.

[0032] In a preferred embodiment, the connecting rod 301 and the air intake plate 302 are integrally formed. This improves the overall strength of the moving part 30 and makes it less prone to damage.

[0033] refer to Figure 1-3 5. In a preferred embodiment, a second detection component 4 is further provided inside the housing 1. The second detection component 4 is spaced apart on one side of the first detection component 3. The second detection component 4 includes a second sensor (not shown, such as a position sensor), a guide part, and a floating part 41 (such as a float). The floating part 41 is sleeved outside the guide part and can float along the axial direction of the guide part. The second sensor is used to sense the position state of the floating part 41. In this embodiment, the second detection component 4 is mainly used to detect changes in water level. When the water level drops to a certain level, the floating part 41 floats to the second position, and the second sensor can detect the sensing signal, thereby triggering the corresponding control action. It should also be noted that the second detection component 4, like the first detection component 3, includes a mounting head. The second sensor and the guide part can be fixed to the mounting head. At the same time, the mounting head and the housing are installed in the same way as the mounting head of the first detection component (i.e., they are detachably connected to the housing by a thread), which facilitates disassembly, assembly, and subsequent maintenance and replacement.

[0034] refer to Figure 5In a preferred embodiment, the guide part is a guide rod 40, and an upper limit plate 42 and a lower limit plate 43 are spaced apart on the guide rod 40. The floating member 41 can rise and fall with the water level and float up and down between the upper limit plate 42 and the lower limit plate 43. The two limit plates are located at different height positions of the guide rod 40 to limit the floating range of the floating member 41. When the floating member 41 floats to the first position, it can abut against the upper limit plate 42. When the floating member 41 floats to the second position, it can abut against the lower limit plate 43. The second sensor is configured to detect the sensing signal when the floating member 41 floats to the second position. In this embodiment, the first position refers to the state when the floating member 41 floats to the highest position, in which the floating member 41 abuts against the upper limit plate 42; the second position refers to the state when the floating member 41 floats to the lowest position, in which the floating member 41 abuts against the lower limit plate 43, which also means that the water level has dropped to a lower level. The second position serves as the main detection position of the second sensor and is used to determine whether the water level in the cavity 10 is too low, thereby triggering corresponding control actions (such as controlling the compressor to stop working).

[0035] In a preferred embodiment, the second position is set below the outlet pipe 12. If the second position is set above the outlet pipe 12, even if the floating element 41 floats to the second position, the water level may still be higher than the outlet of the outlet pipe 12. In this case, water can still flow out normally without triggering the low water level control action. Only when the second position is below the outlet pipe 12 will the floating element 41 float to the second position, meaning the water level has dropped to a lower level, which may affect the normal water flow from the outlet pipe 12. This ensures a timely response when the water level drops to the second position.

[0036] In a further preferred embodiment, a controller (not shown) is also included. The first detection component 3 includes a first sensor, and both the first and second sensors are electrically connected to the controller. In this invention, dual detection of water flow and water level is achieved by using two detection components. The first detection component 3 detects the water flow status through the swinging of the movable part 30, while the second detection component 4 detects changes in water level through the floating of the floating part 41. Signals from both detection components are transmitted to the controller, which performs corresponding control based on the signals from the first and second sensors. This provides dual protection, preventing heat exchanger failure due to the inability to detect malfunctions in one detection component, thus improving reliability.

[0037] refer to Figure 1-3In a preferred embodiment, a sterilization element is also provided inside the shell 1, and the heat exchange coil 2 is sleeved on the outside of the sterilization element. One end of the sterilization element is fixed to the shell 1 (here, "fixed" means relatively fixed), and the other end extends along the height direction of the shell 1. In this embodiment, there is a certain gap between the outer wall of the sterilization element and the heat exchange coil 2 to ensure that the fluid (e.g., water) inside the shell 1 can fully contact the heat exchange coil 2. The main function of the sterilization element is to sterilize the water or other fluids in the cavity 10. In actual use, the heat exchange coil 2 and the sterilization element work together, that is, while the heat exchange coil 2 is exchanging heat, the sterilization element can also sterilize the fluid. This arrangement makes full use of the internal space of the heat exchanger shell 1, ensuring heat exchange efficiency while also achieving fluid sterilization.

[0038] In a preferred embodiment, the disinfection component is a disinfection lamp 13. During use, a power cord is connected to the end of the disinfection lamp 13 that is fixed to the housing 1. The power cord is plugged into a local socket to power on the disinfection lamp 13. The disinfection lamp 13 emits light of a specific wavelength, such as ultraviolet (UV) light. This light can destroy the DNA or RNA of microorganisms (such as bacteria, viruses, algae, etc.), thereby killing or inhibiting their growth and reproduction, achieving the purpose of disinfection. This effectively reduces microbial contamination, improves the hygienic quality of fluids, and prevents equipment corrosion and other problems caused by microbial growth.

[0039] refer to Figure 3 In a further preferred embodiment, a temperature-sensing blind tube 14 is also provided inside the housing 1, and a temperature-sensing probe is installed inside the temperature-sensing blind tube 14 for detecting the fluid temperature inside the housing 1.

[0040] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
