Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a multi-point testing device for the thermal performance of heat pipe radiators. Background Technology

[0002] As electronic devices become smaller and denser, heat pipe cooling solutions are often used to address the problem of slow heat diffusion. Accurate testing of each heat pipe in the heat source distribution has become a core element in ensuring device reliability.

[0003] However, traditional testing methods can usually only test one set of modules. This means that when faced with the testing requirements of multiple heat pipes, it is impossible to comprehensively determine whether each heat pipe has a problem at once. Even if there are a few devices that can test multiple heat pipes, there is still a phenomenon that the temperature sensor and the heat pipe do not make tight contact. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-point testing device for the thermal performance of heat pipe radiators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-point testing device for the thermal performance of a heat pipe radiator includes a base plate and multiple probes. Temperature sensors are mounted on the bottom of each probe. A support frame is fixedly connected to the upper surface of the base plate. Two first slide rails are fixedly connected to one side of the support frame, and a sliding plate is movably connected between the two first slide rails. A power assembly for moving the sliding plate is provided at the top of the support frame. Multiple sliding cylinders are fixedly connected to the bottom of the sliding plate. The interiors of the multiple sliding cylinders are slidably connected to the multiple probes via guide components. The guide components include two sliding grooves, both of which are formed on the inner walls of the two sides of the sliding cylinders. Limiting blocks are fixedly connected to the outer walls of both sides of the probes, and the limiting blocks are slidably connected to the adjacent sliding grooves. Springs are fixedly connected to the inner top walls of the multiple sliding cylinders, with the bottom ends of the springs contacting the outer top walls of the probes. A support assembly is provided on the upper surface of the base plate.

[0006] As a further embodiment of this utility model, the power assembly includes a first electric push rod, which is fixed to the top of the support frame by bolts, and the extended end of the first electric push rod passes through the support frame and is fixed to the slide plate.

[0007] As a further embodiment of this utility model, two telescopic rods are fixedly connected to the top of the support frame, and the extended ends of the telescopic rods pass through the support frame and are fixed to the slide plate.

[0008] As a further embodiment of this invention, the first electric push rod is located in the middle position between the two telescopic rods.

[0009] As a further embodiment of this utility model, the support assembly includes two second slide rails, which are fixed to the upper surface of the base plate by bolts. A slider is movably connected to the outer side between the two second slide rails. A first carrier plate and a second carrier plate are fixedly connected to the outer walls of the two sides of the slider, respectively. A second electric push rod is fixedly connected to the upper surface of the base plate, and the extended end of the second electric push rod is fixed to the slider.

[0010] As a further embodiment of this utility model, multiple slots are provided on the upper surfaces of both the first and second carrier plates, and the multiple slots are symmetrically distributed in an array at multiple corners of the first and second carrier plates.

[0011] As a further embodiment of this utility model, a plug is inserted into one of the slots in the slot array located at the same corner, and the top of the plug passes through the slot and is fixedly connected to an L-shaped block.

[0012] As a further embodiment of this utility model, rollers are fixedly connected to the bottom of both the first and second carrier plates, and the rollers are in contact with the upper surface of the base plate.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model, by equipping multiple probes, enables the temperature sensor to simultaneously contact multiple heat pipes on the heat pipe radiator, thereby achieving synchronous detection of the temperature of multiple heat pipes. Compared with single-point detection, this not only improves testing efficiency but also provides a more comprehensive reflection of the overall thermal performance distribution of the radiator.

[0014] 2. By using the guide assembly and spring in combination, when the temperature sensor encounters resistance in contact with the heat pipe, the spring contracts and the limiting block moves upward along the slide groove. This design not only enables the temperature sensor to fit against the surface of the heat pipe, further ensuring the accuracy of temperature measurement, but also avoids damage to the temperature sensor or heat pipe caused by excessive pushing of the first electric push rod, thus extending the service life of the device and protecting the product being tested.

[0015] 3. In this utility model, by setting up a support component, the positions of the first carrier plate and the second carrier plate are moved, thereby swapping the positions of the two carrier plates at the bottom of the temperature sensor. While the device is detecting the temperature of the heat pipe radiator on one carrier plate, the operator can load or unload the radiator on the other carrier plate, saving the waiting time for loading and unloading during the detection process and improving the detection efficiency.

[0016] 4. This utility model, through the practical cooperation between the plug and the slot, allows the position of the L-shaped block to be adjusted, enabling the device to position heat pipe radiators of different lengths and widths within the slot distribution range, thus enhancing the applicability of the device to products of different specifications.

Detailed Implementation

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0020] Reference Figures 1-4 A multi-point testing device for the thermal performance of a heat pipe radiator includes a base plate 7 and multiple probes 18. A support frame 6 is fixed to the upper surface of the base plate 7 by bolts. Two first slide rails 4 are fixed to one side of the support frame 6 by bolts, and a slide plate 1 is slidably connected between the two first slide rails 4. The top of the support frame 6 is provided with a power component that drives the slide plate 1 to move. The power component includes a first electric push rod 3, which is fixed to the top of the support frame 6 by bolts. The extended end of the first electric push rod 3 passes through the support frame 6 and is fixed to the slide plate 1. Multiple sliding cylinders 5 are fixed to the bottom of the slide plate 1 by bolts. The interior of each sliding cylinder 5 is slidably connected to multiple probes 18 through guide components. Temperature sensors are installed at the bottom of each probe 18. The model of the temperature sensor can be selected according to the actual situation, such as DS18B20. Multiple temperature sensors are integrated with the same circuit board. The circuit board is installed on the slide plate 1 and includes external sockets. The first electric push rod 3 extends, causing the slide plate 1 to move downward along the first slide rail 4, thereby causing the slide cylinder 5 to drive the probe 18 downward, so that the temperature sensors at the bottom of the multiple probes 18 come into contact with the heat pipes on the heat pipe radiator, and the temperature sensors detect the temperature of the multiple heat pipes on the heat pipe radiator.

[0021] In particular, the guide assembly includes two slides 16, both of which are formed on the inner walls of both sides of the slide cylinder 5. Limiting blocks 17 are bonded to both outer walls of the probe 18, and the limiting blocks 17 are slidably connected to the slides 16 at adjacent positions. Springs 19 are welded to the inner top walls of multiple slide cylinders 5, and the bottom end of the springs 19 contacts the outer top wall of the probe 18. The springs 19 can be selected as fatigue-resistant springs with suitable elastic coefficients so that they can just push the probe 18 out and reset. During the downward movement of the slide cylinder 5, if the temperature sensor at the bottom of the probe 18 is resisted by the heat sink, the spring 19 contracts and the limiting block 17 moves upward along the slide groove 16. This not only allows multiple temperature sensors to fit more closely to the heat pipe, but also prevents the first electric push rod 3 from directly pushing the probe 18 to move excessively and impacting the heat pipe heat sink, which could damage the temperature sensor or the heat pipe heat sink.

[0022] Two telescopic rods 2 are fixed to the top of the support frame 6 by bolts, and the extended ends of the telescopic rods 2 pass through the support frame 6 and are fixed to the slide plate 1. The telescopic rods 2 can guide the slide plate 1 and prevent the slide plate 1 from tilting during movement. The first electric push rod 3 is located in the middle position between the two telescopic rods 2.

[0023] It should be noted that the upper surface of the base plate 7 is provided with a support assembly, which includes two second slide rails 12. The two second slide rails 12 are fixed to the upper surface of the base plate 7 by bolts. A slider 9 is slidably connected between the two second slide rails 12 on the outer side. The outer walls on both sides of the slider 9 are respectively fixed with a first carrier plate 8 and a second carrier plate 10 by bolts. The upper surface of the base plate 7 is fixed with a second electric push rod 11 by bolts. The extended end of the second electric push rod 11 is fixed with the slider 9. The extension and retraction of the second electric push rod 11 causes the slider 9 to move along the second slide rail 12, thereby moving the first carrier plate 8 and the second carrier plate 10. This allows the positions of the two carrier plates at the bottom of the temperature sensor to be swapped, so that while the device detects the temperature of the heat pipe on one carrier plate, the operator can place and position the heat pipe on the other carrier plate, saving the time of loading and unloading materials.

[0024] Multiple slots 13 are provided on the upper surfaces of the first carrier plate 8 and the second carrier plate 10. The multiple slots 13 are symmetrically distributed in an array at multiple corners of the first carrier plate 8 and the second carrier plate 10. In the array of slots 13 located at the same corner, a plug 14 is inserted into one of the slots 13. The top of the plug 14 passes through the slot 13 and is welded with an L-shaped block 15. By using the plug 14 and the slot 13 together, the position of the L-shaped block 15 can be adjusted, which makes it convenient for the staff to position heat pipe radiators of different sizes within the distribution range of the slots 13.

[0025] The bottom of the first carrier plate 8 and the second carrier plate 10 are both fixed with rollers by bolts, and the rollers are in contact with the upper surface of the base plate 7. The rollers can not only provide auxiliary support for the first carrier plate 8 and the second carrier plate 10, but also make the first carrier plate 8 and the second carrier plate 10 move more smoothly. A circuit board is fixed on the slide plate 1.

[0026] The temperature sensor on probe 18 is electrically connected to the circuit board via a spring-wire type data transmission line passing through slide cylinder 5. The temperature sensor is tightly mounted on the contact end of probe 18 to directly acquire the temperature data of the contact point.

[0027] The first electric push rod 3 and the second electric push rod 11 are connected to a controller. Working principle: When it is necessary to detect the temperature of the heat pipes on a heat pipe radiator, First, adjust the position of the insert block 14 into the slots 13 concentrated at each corner of the first carrier plate 8 and the second carrier plate 10 according to the length and width of the heat pipe radiator to be tested. Then, move the L-shaped block 15 to the required position and place the two heat pipe radiators to be tested on the first carrier plate 8 and the second carrier plate 10 respectively. The position of the heat pipe radiator is restricted by the L-shaped block 15. Start the first electric push rod 3. The first electric push rod 3 extends to make the slide plate 1 move downward along the first slide rail 4, thereby causing the slide cylinder 5 to drive the probe 18 downward, so that the temperature sensors on the multiple probes 18 come into contact with the heat pipes on the heat pipe radiator, and the temperature sensors detect the temperature of the multiple heat pipes on the heat pipe radiator. After testing, the temperature sensor's data transmission line uses a high-speed, low-interference thermocouple to transmit the data collected by the temperature sensor to external data analysis software in real time. The external data analysis software then performs real-time analysis on the collected temperature data. During the downward movement of the slide cylinder 5, if the temperature sensor at the bottom of the probe 18 is resisted by the heat sink, the spring 19 contracts and the limit block 17 moves upward along the slide groove 16. This not only allows multiple temperature sensors to fit more closely to the heat pipe, but also prevents the first electric push rod 3 from directly pushing the probe 18 to move excessively, which could damage the temperature sensor or the heat pipe. After the test is completed, the first electric push rod 3 is retracted, causing the probe 18 to move the temperature sensor upward and reset. When it is necessary to move the second carrier plate 10 to the bottom of the temperature sensor, the second electric push rod 11 is activated. The second electric push rod 11 retracts, causing the slider 9 to move along the second slide rail 12, thereby moving the first carrier plate 8 and the second carrier plate 10. This causes the heat pipe radiator on the first carrier plate 8, after testing, to move out of the bottom of the temperature sensor on the probe 18, and the untested heat pipe radiator on the second carrier plate 10 to move to the bottom of the temperature sensor on the probe 18. This swaps the positions of the two carrier plates located at the bottom of the temperature sensor, allowing the operator to place and position the heat pipe on the other carrier plate while the device tests the temperature of the heat pipe on one carrier plate, saving loading and unloading time and facilitating subsequent re-testing.
