Description

Technical Field

[0001] This utility model relates to the technical field of liquid-cooled temperature sensing devices, and in particular to a temperature sensing device and a liquid cooling system. Background Technology

[0002] Temperature sensors are needed inside the water pipes of a liquid cooling system for real-time monitoring of water temperature changes. In existing liquid cooling systems, temperature sensors are usually fixed inside the water pipes. When a temperature sensor malfunctions, the entire water pipe containing the sensor must be disassembled before a new sensor can be installed. This process takes a lot of time, and the temperature sensor also needs to be removed after the water pipes are disassembled, which affects the efficiency of disassembly and installation.

[0003] In the prior art, a temperature sensing device and liquid cooling system disclosed in CN221882825U include a water-cooled pipe, a measuring component, and a heat-conducting component. The water-cooled pipe includes a pipe body and an assembly. The pipe body has a flow cavity inside. The assembly is connected to the pipe body, and one end of the assembly extends into the flow cavity. The assembly has an assembly cavity inside. The measuring component includes terminals, a thermistor, and a connector. The terminals are connected to the thermistor. The connector is sleeved on the terminals and fixedly connected to them. The connector is detachably disposed in the assembly cavity. The heat-conducting component is disposed between the inner wall of the end of the assembly extending into the flow cavity and the thermistor. This liquid cooling system includes a temperature sensing device. The temperature sensing device of this application allows for quick replacement of the measuring component, and the steady-state temperature fluctuation of the measuring component during temperature sensing is small, resulting in more accurate temperature sensing results.

[0004] The measuring component of this application is located inside the assembly cavity, which is situated within a water-cooling pipe. When the measuring component measures the temperature, the cavity wall of the assembly cavity needs to conduct heat. However, conducting heat using the cavity wall of the assembly cavity takes a certain amount of time, which can easily affect the accuracy of the real-time temperature sensor measurement data.

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a temperature sensing device and a liquid cooling system to solve the technical problems mentioned in the background.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A temperature sensing device includes a liquid cooling pipe and a temperature sensor. The liquid cooling pipe has an installation hole on its outer periphery, and a probe is fixedly connected in the installation hole. The probe has a through hole at the bottom of its outer periphery, and a switching element is provided inside the probe.

[0008] The switching component includes a lower slider, an upper slider, and connecting posts. The lower slider is slidably connected to the bottom of the detection tube, and the upper slider is slidably connected to the top of the detection tube. A gap is left between the bottom side of the upper slider and the top side of the lower slider. There are several connecting posts, which are arranged in a circular array and fixedly connected to the bottom side of the upper slider. The bottom end of the connecting post is connected to the top side of the lower slider. The temperature sensor is mounted on the top of the upper slider through a mounting component.

[0009] In a preferred embodiment, the present invention can be further configured such that both the upper slider and the lower slider are dynamically sealed within the detection tube, and the gap between the upper slider and the lower slider is aligned with the through hole.

[0011] In a preferred embodiment, the present invention can be further configured as follows: both the positioning disk and the upper slider have clearance holes on their top sides; a protective tube is provided on the outside of the wire at the bottom of the temperature sensor; the protective tube is connected to the bottom side of the positioning disk; the bottom end of the protective tube extends to the bottom of the upper slider; and the thermistor at the end of the upper wire of the temperature sensor is fixedly connected to the bottom end of the protective tube.

[0014] In a preferred embodiment, the present invention can be further configured such that: a limiting ring is connected to the inner wall of the probe tube, the limiting ring is located above the through hole, and the top side of the limiting ring is in contact with the bottom side of the upper slider.

[0015] A liquid cooling system employing the temperature sensing device described above.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. This temperature sensing device eliminates the cavity wall between the thermistor at the sensing end of the temperature sensor and the water, allowing the thermistor at the sensing end of the temperature sensor to directly contact the water after waterproofing treatment. This reduces the temperature conduction time during detection, improves the accuracy of the temperature sensor in detecting the water temperature inside the liquid cooling pipe, and avoids the effect of temperature conduction delay.

[0018] 2. In this temperature sensing device, an upper groove is formed on the top side of the upper slider. By connecting the positioning plate and the temperature sensor, the positioning plate is threadedly connected in the upper groove. At this time, the temperature sensor is fixed on the top side of the upper slider. Then, the detection end of the temperature sensor is extended between the upper slider and the lower slider to complete the installation of the temperature sensor.

[0019] 3. In this temperature sensing device, a fixed ring is threadedly connected in an annular groove, and a fixed plate is connected to the top side of the fixed ring. At this time, the fixed ring at the bottom of the fixed plate is threadedly connected in the annular groove, and the bottom side wall of the fixed plate will abut against the upper slider, thus confining the upper slider inside the detection tube, thereby achieving the effect of sealing the detection tube and confining the upper slider.

[0020] 4. In this temperature sensing device, a support spring is connected to the bottom side wall of the probe tube. The top of the support spring is connected to the lower slider. Therefore, after the restriction on the top of the upper slider is released, the support spring returns to its original state, thereby pushing the lower slider to move upward and blocking the through hole. This achieves the purpose of automatically blocking the through hole after the part that restricts the upper slider in the mounting component is disassembled, so as to facilitate the subsequent disassembly of the temperature sensor.

[0021] 5. This liquid cooling system allows for the installation and removal of temperature sensing devices without disassembling the entire pipe, improving efficiency during installation and removal. It also allows the sensing end of the temperature sensor to directly contact the water, reducing the delay in temperature conduction and improving detection accuracy. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example:

[0030] Reference Figures 1-3 The present invention discloses a temperature sensing device, including a liquid cooling pipe 1 and a temperature sensor 2. The liquid cooling pipe 1 has an installation hole 3 on its outer periphery, and a probe 4 is fixedly connected in the installation hole 3. The probe 4 has a through hole 5 at the bottom of its outer periphery, and a switching element 6 is provided in the probe 4.

[0031] The switching component 6 includes a lower slider 7, an upper slider 8, and connecting posts 9. The lower slider 7 is slidably connected to the bottom of the detection tube 4, and the upper slider 8 is slidably connected to the top of the detection tube 4. A gap is left between the bottom side of the upper slider 8 and the top side of the lower slider 7. There are several connecting posts 9, which are arranged in a ring array and fixedly connected to the bottom side of the upper slider 8. The bottom end of the connecting post 9 is connected to the top side of the lower slider 7. The temperature sensor 2 is mounted on the top of the upper slider 8 through the mounting component 10.

[0032] In this embodiment, reference Figure 2 For temperature sensor 2, when installing it, the thermistor at the probe end should be waterproofed, for example, by wrapping it with a thin film or coating it with a waterproof layer. (Refer to...) Figure 2 The upper slider 8 is then inserted into the detection tube 4. The temperature sensor 2 is then fixed to the upper slider 8 using the mounting bracket 10, and the upper slider 8 is pressed down. During this downward movement, the connecting post 9 moves, which in turn moves the lower slider 7. (Refer to...) Figure 3The through hole 5 aligns the gap between the upper slider 8 and the lower slider 7 with the through hole 5. The upper slider 8 and the lower slider 7 are dynamically sealed inside the detection tube 4. At this time, the temperature sensing device is installed. When the water in the liquid cooling tube 1 flows, it will pass through the through hole 5 and enter the gap between the upper slider 8 and the lower slider 7, and come into contact with the thermistor at the detection end of the temperature sensor 2. At this time, the thermistor can directly detect the temperature of the water in the liquid cooling tube 1, thereby reducing the detection delay and improving the detection accuracy.

[0033] refer to Figure 2 When disassembling the temperature sensor 2, the upper slider 8 is released from its constraint by the mounting part 10, which then moves the upper slider 8 upward. This, in turn, moves the lower slider 7 through the connecting column 9, causing the lower slider 7 to block the through hole 5 on the detection tube 4. At this point, the mounting part 10 is used to release the constraint on the temperature sensor 2, thereby allowing the temperature sensor 2 to be pulled out. This achieves the effect of disassembling the temperature sensor 2 without disassembling the pipe, allowing the temperature sensor 2 to be disassembled directly, and preventing water from flowing out of the liquid cooling pipe 1.

[0034] In a further preferred embodiment of this utility model, such as Figure 2 As shown, both the upper slider 8 and the lower slider 7 are dynamically sealed inside the detection tube 4, and the gap between the upper slider 8 and the lower slider 7 is aligned with the through hole 5.

[0035] In this embodiment, reference Figure 2 The upper slider 8, the lower slider 7, and the upper slider 8 are all dynamically sealed inside the detection tube 4 to prevent water in the liquid cooling tube 1 from flowing out of the detection tube 4 when the temperature sensor 2 is disassembled. This prevents insufficient water volume in the liquid cooling tube 1 after water flows out, which would affect the use of the liquid cooling system.

[0036] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the mounting component 10 includes an inner locking part and an outer locking part. The inner locking part includes an upper groove 11, which is formed on the top side of the upper slider 8. A positioning disk 12 is internally threaded into the upper groove 11, and the temperature sensor 2 is connected to the top side of the positioning disk 12.

[0037] In this embodiment, reference Figure 4 The mounting component 10 has an upper groove 11 on the top side of the upper slider 8. The positioning plate 12 is connected to the temperature sensor 2, so that the positioning plate 12 is threaded into the upper groove 11. At this time, the temperature sensor 2 is fixed on the top side of the upper slider 8. Then, the detection end of the temperature sensor 2 is extended between the upper slider 8 and the lower slider 7 to complete the installation of the temperature sensor 2.

[0038] In a further preferred embodiment of this utility model, such as Figure 3 As shown, both the positioning disk 12 and the upper slider 8 have clearance holes 13 on their top sides. A protective tube 14 is provided on the outside of the wire at the bottom of the temperature sensor 2. The protective tube 14 is connected to the bottom side of the positioning disk 12. The bottom end of the protective tube 14 extends to the bottom of the upper slider 8. The thermistor at the end of the upper wire of the temperature sensor 2 is fixedly connected to the bottom end of the protective tube 14.

[0039] In this embodiment, reference Figure 3 The clearance holes 13 are provided on the top side of the upper slider 8 of the positioning block. The two clearance holes 13 are positioned correspondingly and connected to each other. The protective tube 14 is then connected to the bottom side of the positioning plate 12 so that the detection wire of the temperature sensor 2 passes through the protective tube 14. At the same time, the thermistor at the detection end of the temperature sensor 2 is fixed to the bottom side of the protective tube 14. At this time, the bottom end of the protective tube 14 and the position of the thermistor can be waterproofed to prevent the circuit from getting wet and affecting the use of the temperature sensor 2.

[0040] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the outer locking part includes an annular groove 15, which is formed at the top of the side wall of the detection tube 4. A fixing ring 16 is threaded into the annular groove 15, and a fixing plate 17 is fixedly connected to the top of the fixing ring 16. The bottom side of the fixing plate 17 is in contact with the top side of the upper slider 8.

[0041] In this embodiment, reference Figure 4 The detector tube 4 has an annular groove 15 at the top of its side wall. A fixing ring 16 is threaded into the annular groove 15, and a fixing plate 17 is connected to the top side of the fixing ring 16. At this time, the fixing ring 16 at the bottom of the fixing plate 17 is threaded into the annular groove 15, and the bottom side wall of the fixing plate 17 will abut against the upper slider 8, thus confining the upper slider 8 within the detector tube 4, thereby achieving the effect of sealing the detector tube 4 and confining the upper slider 8.

[0042] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the bottom end of the detection tube 4 is closed, and a support spring 18 is connected to the inner bottom side wall of the detection tube 4. The top end of the support spring 18 is connected to the bottom side of the lower slider 7.

[0043] In this embodiment, reference Figure 4The bottom of the probe tube 4 is enclosed, and a support spring 18 is connected to the bottom wall of the probe tube 4. The top of the support spring 18 is connected to the lower slider 7. Therefore, after the restriction on the top of the upper slider 8 is released, the support spring 18 returns to its original state, thereby pushing the lower slider 7 to move upward and blocking the through hole 5. This achieves the goal of automatically blocking the through hole 5 after the part of the mounting piece 10 that restricts the upper slider 8 is disassembled, so as to facilitate the subsequent disassembly of the temperature sensor 2.

[0044] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a limiting ring 19 is connected to the inner wall of the probe tube 4. The limiting ring 19 is located above the through hole 5, and the top side of the limiting ring 19 is in contact with the bottom side of the upper slider 8.

[0045] In this embodiment, reference Figure 4 The inner wall of the probe tube 4 is connected to a limiting ring 19. When the upper slider 8 is limited by the mounting part 10, the bottom end of the upper slider 8 touches the limiting ring 19 so as to lock the upper slider 8 with the mounting part 10, so as to prevent the lower slider 7 from shaking after the water flow washes it, thus affecting the detection of the temperature sensor 2.

[0046] In addition, after the upper slider 8 is released from its restraint, the support spring 18 pushes the lower slider 7 to move upward, thereby pushing the lower slider 7 to contact the restraining ring 19. The lower slider 7 uses the spring's rebound force to firmly contact the restraining ring 19, thus facilitating the sealing of the through hole 5.

[0047] Example 2:

[0048] Reference Figure 1-4 A liquid cooling system employing the temperature sensing device described above.

[0049] In this embodiment, the liquid cooling system allows for the installation and removal of the temperature sensing device without disassembling the entire pipe, improving the efficiency of disassembly and installation. At the same time, it allows the sensing end of the temperature sensor 2 to directly contact the water, reducing the delay in temperature conduction and improving the detection accuracy.

[0050] The implementation principle of the above embodiment is as follows: First, the temperature sensor 2 is fixed to the upper slider 8 using the mounting part 10. Then, the upper slider 8 is limited by the mounting part 10 so that the upper slider 8 is submerged in the detection tube 4, and the thermistor at the detection end of the temperature sensor 2 is aligned with the through hole 5 for easy detection. At this time, when installing the temperature sensor 2, it is not necessary to disassemble the entire pipe, and the detection end of the temperature sensor 2 can directly contact the water, which improves the detection accuracy.

[0051] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
