Description

Technical Field

[0001] This utility model relates to the production of heat pipes, and in particular to a heat pipe thermal conductivity testing device. Background Technology

[0002] Existing heat pipe thermal conductivity testing equipment includes a base and a testing mechanism. The testing mechanism comprises two heat conductors and two temperature sensors. The two heat conductors contact the two ends of the heat pipe, respectively. The first heat conductor has a heater and heats the first end of the heat pipe, while the second heat conductor is at room temperature and dissipates heat to the second end. The two temperature sensors detect temperature changes at both ends of the heat pipe to determine if its thermal conductivity is up to standard. However, in existing heat pipe thermal conductivity testing equipment, the heat pipe is placed directly on the heat conductors, resulting in relatively loose contact. This leads to significant fluctuations in the heat transfer effect between the heat conductors and the heat pipe, affecting the accuracy of the thermal conductivity test. Furthermore, differences in storage environment can cause significant variations in the initial temperature of the heat pipe, which may also affect the accuracy of the thermal conductivity test. Utility Model Content

The pipe immersion tank is disposed on the base. The transfer mechanism is disposed on the base and can move the heat pipe from the pipe immersion tank to the heat pipe mounting groove.

[0005] The heat pipe thermal conductivity testing device according to the present invention has at least the following beneficial effects: the heat pipe is first placed in a whole-pipe immersion tank for whole-pipe immersion, so that the temperature of the heat pipe is similar throughout, reducing the influence of the initial temperature of the heat pipe on the accuracy of its thermal conductivity testing. Then, the material transfer mechanism moves the heat pipe in the whole-pipe immersion tank to the thermal conductivity testing mechanism, and places both ends of the heat pipe into the heat pipe placement slots of two heat conductors respectively. Then, the thermal conductivity of the heat pipe is tested by two temperature sensors and two heat conductors. The outer surface of the heat pipe can fully contact the heat transfer through the residual water with the wall of the heat pipe placement slot, reducing the fluctuation of the heat transfer effect between the heat conductor and the heat pipe, thereby improving the accuracy of the thermal conductivity testing of the heat pipe itself.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] Reference Figures 1 to 5 This utility model discloses a heat pipe thermal conductivity testing device, comprising a base 100, a thermal conductivity testing mechanism 200, a pipe immersion tank 300, and a transfer mechanism 400. The thermal conductivity testing mechanism 200 is disposed on the base 100 and includes two heat conductors 210 and two temperature sensors 220. The two heat conductors 210 are arranged side-by-side at intervals in the left-right direction, and each heat conductor 210 has a heat pipe mounting groove 211 in the left-right direction. One of the heat conductors 210 is equipped with a heater. The two temperature sensors 220 correspond one-to-one with the two heat conductors 210 and are used to detect the temperature of the heat pipe area located in the corresponding heat pipe mounting groove 211. The pipe immersion tank 300 is disposed on the base 100. The transfer mechanism 400 is disposed on the base 100 and can move the heat pipe from the pipe immersion tank 300 to the heat pipe mounting groove 211.

[0037] The heat pipe is first immersed in the immersion tank 300 to ensure that the temperature of the heat pipe is uniform throughout, thus reducing the impact of the initial temperature of the heat pipe on the accuracy of its thermal conductivity test. Then, the transfer mechanism 400 moves the heat pipe in the immersion tank 300 to the thermal conductivity test mechanism 200, and places both ends of the heat pipe into the heat pipe placement slots 211 of the two heat conductors 210 respectively. Subsequently, the thermal conductivity of the heat pipe is tested by two temperature sensors 220 and two heat conductors 210. The outer surface of the heat pipe can fully contact the wall of the heat pipe placement slot 211 through the residual water, reducing the fluctuation of the heat transfer effect between the heat conductors 210 and the heat pipe, thereby improving the accuracy of the thermal conductivity test of the heat pipe itself.

[0038] Specifically, after the two ends of the heat pipe are placed into the heat pipe mounting groove 211 of the two heat conductors 210, the heater heats one of the heat conductors 210, that is, heats one end of the heat pipe. After a predetermined time, the two temperature sensors 220 detect the temperature at both ends of the heat pipe respectively. If the temperature at both ends of the heat pipe is within the preset range, it proves that the heat conduction capacity of the heat pipe is qualified.

[0039] In the embodiments, reference is made to Figure 2 and Figure 3 The thermal conductivity detection mechanism 200 includes a lifting frame 230 and a lifting driver 240. The lifting frame 230 is movably mounted on the base 100 in the vertical direction. The temperature sensor 220 is mounted on the lifting frame 230. The heat conductor 210 is mounted on the base 100 and located below the temperature sensor 220. The heat pipe mounting groove 211 is located on the upper side of the heat conductor 210. The lifting driver 240 is used to drive the lifting frame 230 to rise and fall.

[0040] Initially, the lifting frame 230 and temperature sensor 220 are far from the heat pipe mounting slot 211, making it easier for the material transfer mechanism 400 to place the heat pipe to be tested into the heat pipe mounting slot 211. After the heat pipe is placed into the heat pipe mounting slot 211, the lifting driver 240 can drive the lifting frame 230 to descend and get closer to the heat pipe, facilitating more accurate contact temperature detection of the heat pipe. This results in higher detection accuracy and relatively convenient loading and unloading.

[0041] Specifically, the temperature sensor 220 is a contact temperature sensor 220, such as a resistance temperature sensor 220 or a thermocouple temperature sensor 220. It is conceivable that in some other embodiments, the temperature sensor 220 may also be a non-contact temperature sensor 220, such as an infrared temperature sensor 220, which is not limited here.

[0042] Specifically, the lifting drive 240 is a cylinder, which directly drives the lifting frame 230 to move up and down. Alternatively, the lifting frame 230 can be movably connected to the base 100 via a slide rail, slider, or guide column / sleeve, and driven to lift by the lifting drive 240. The lifting drive 240 can also employ a structure such as a hydraulic cylinder or an electric cylinder.

[0043] In the embodiments, reference is made to Figure 3 One of the heat conductors 210 is connected to the base 100 in an adjustable position in the left and right direction, and the two temperature sensors 220 are set on the lifting frame 230 in an adjustable position in the left and right direction, so that the two heat conductors 210 and the two temperature sensors 220 can be adapted to the detection of heat pipes of different lengths, thereby improving the versatility of the heat conduction detection equipment.

[0044] Specifically, one heat conductor 210 is fixed to the base 100 by screws, and the other heat conductor 210 is slidably connected to the base 100 in the left and right direction through a slide rail and slide groove structure. The position of the heat conductor 210 can be adjusted by a screw in conjunction with a strip hole. That is, the heat conductor 210 is provided with a strip hole extending in the left and right direction. The screw passes through the strip hole. When the screw is loosened, the left and right position of the heat conductor 210 can be adjusted. When the screw is tightened, the position can be locked.

[0045] It is conceivable that multiple screw holes could be arranged in a left-right direction, and the position could be adjusted left-right by switching the heat conductor 210 to one of the screw holes.

[0046] Specifically, two temperature sensors 220 are slidably connected to the lifting frame 230 in the left-right direction via a slide rail slider structure, and their left-right positions are adjusted by screws through slotted holes. Alternatively, multiple screw holes could be arranged along the left-right direction on the lifting frame 230, allowing the left-right position adjustment by switching the temperature sensor 220 to one of these screw holes.

[0047] It is conceivable that both heat conductors 210 can be adjusted left and right; or one of the temperature sensors 220 can be adjusted left and right, as long as the temperature sensor 220 and the corresponding heat conductor 210 are vertically aligned.

[0048] In the embodiments, reference is made to Figure 3 Three heat pipe mounting slots 211 with different cross-sectional sizes or shapes are arranged at intervals along the front-back direction on the upper side of the heat conductor 210. Since the heat pipes have different sizes or shapes, in order to increase the contact area between the heat conductor 210 and the heat pipe to improve heat transfer capacity, three heat pipe mounting slots 211 of different specifications are made to adapt to the specifications of the heat pipe to be tested. The same heat conductor 210 can be used to adapt to three different specifications of heat pipes, eliminating the need for frequent replacement of the heat conductor 210, thus improving its versatility and reducing production and usage costs.

[0049] Specifically, of the three heat pipe mounting slots 211, two are semi-circular arc through slots with different radii, and the other is a rectangular through slot.

[0050] Specifically, the heat conductor 210 is provided with three heat pipe mounting slots 211. It is conceivable that in other embodiments, the heat conductor 210 may also be provided with two, four or more heat pipe mounting slots 211, and those skilled in the art can choose according to actual needs.

[0051] In the embodiments, reference is made to Figure 4 It also includes a water-immersion bracket 500, which is disposed within the whole-pipe water immersion tank 300. The water-immersion bracket 500 includes two support blocks 510 arranged at intervals in the left-right direction. A water-immersion support groove 511 is provided on the upper side of the support block 510, and a gripping clearance area 501 is formed between two adjacent support blocks 510. The water-immersion bracket 500 supports the heat pipe through the water-immersion support groove 511 on the two support blocks 510, so that the heat pipe can be suspended and immersed in water within the whole-pipe water immersion tank 300, improving the water immersion temperature uniformity effect. The water-immersion support groove 511 can position the heat pipe, and the gripping clearance area 501 can facilitate the material transfer mechanism 400 to extend into the whole-pipe water immersion tank 300 to grip the small heat pipe.

[0052] Specifically, the two support blocks 510 of the water-immersing bracket 500 can be adjusted left and right using screws through the slotted holes to accommodate heat pipes of different lengths.

[0053] In the embodiments, reference is made to Figure 5 It also includes a feeding mechanism 600, which is mounted on the base 100 and has a storage hopper 610. The transfer mechanism 400 can move the heat pipe from the feeding mechanism 600 to the pipe immersion tank 300. The storage hopper 610 is provided to facilitate the batch storage of heat pipes and to provide heat pipes to the transfer mechanism 400.

[0054] In the embodiments, reference is made to Figure 5 The feeding mechanism 600 also includes a feeding bracket 620 and a feeding driver. The feeding bracket 620 is movably disposed on the base 100 in the vertical direction. The feeding bracket 620 passes through the bottom wall of the storage hopper 610. The upper end of the feeding bracket 620 is provided with a feeding support groove 621. The feeding driver is disposed on the base 100 and is used to drive the feeding bracket 620 to rise and fall.

[0055] When the feeding bracket 620 rises, the feeding support groove 621 can support a heat pipe and raise it to a predetermined height. Then, the transfer mechanism 400 directly grabs the heat pipe and transfers it into the whole pipe immersion tank 300 for immersion. By setting up the feeding bracket 620, the transfer mechanism 400 does not need to directly grab the heat pipes from the numerous heat pipes in the storage hopper 610. Instead, the feeding bracket 620 supports one heat pipe, and then the transfer mechanism 400 directly grabs that heat pipe. This simplifies the process of the transfer mechanism 400 in moving the heat pipe and simplifies the equipment structure.

[0056] Specifically, the feeding drive can be a linear drive, such as a pneumatic cylinder, electric cylinder, hydraulic cylinder, or motor with a lead screw structure, to drive the feeding bracket 620 to rise and fall. The feeding bracket 620 can be movably connected to the machine base 100 in the vertical direction via, for example, a guide post and guide sleeve structure or a slide rail and slider structure.

[0057] Specifically, both sides of the storage hopper 610 are equipped with adjusting plates 611 through strip holes and screws. The two adjusting plates 611 can be adjusted to the left and right positions so that the distance between the two adjusting plates 611 is adjustable to accommodate heat pipes of different lengths.

[0058] In the embodiments, reference is made to Figure 2The thermal conductivity testing mechanism 200, the pipe immersion tank 300, and the feeding mechanism 600 are arranged sequentially in the front-to-back direction. The transfer mechanism 400 includes a first transfer frame 410, a first transfer driver 420, a second transfer frame 430, a second transfer driver 440, and a pipe clamp 450. The first transfer frame 410 is movably mounted on the base 100 in the front-to-back direction. The first transfer driver 420 is used to drive the first transfer frame 410 to move back and forth. The second transfer frame 430 is movable in the up-down direction. The second transfer driver 440 is mounted on the first transfer frame 410 and is used to drive the second transfer frame 430 to move up and down. The pipe clamp 450 is mounted on the second transfer frame 430.

[0059] The above-described structural layout makes the thermal conductivity detection mechanism 200, the pipe immersion tank 300, and the feeding mechanism 600 relatively compact, resulting in a small equipment size. The transfer mechanism 400 can drive the first transfer frame 410 to move back and forth through the first transfer driver 420, and cooperate with the second transfer driver 440 to drive the second transfer frame 430 to move up and down, so that the pipe clamp 450 can move back and forth between the thermal conductivity detection mechanism 200, the pipe immersion tank 300, and the feeding mechanism 600. This makes the transfer mechanism 400 relatively simple in structure and easy to implement.

[0060] Specifically, the tube holder 450 is a gripper cylinder, the first transfer frame 410 is slidably connected to the base 100 through a slide rail slider structure, the first transfer driver 420 is a cylinder, and the second transfer driver 440 is a cylinder, which is directly connected to drive the second transfer frame 430 to rise and fall.

[0061] Specifically, there are two tube holders 450. The two tube holders 450 are arranged in a front-to-back direction and installed on the second transfer rack 430. The tube holder 450 located at the rear moves between the loading bracket 620 and the whole tube immersion tank 300, while the tube holder 450 located at the front moves between the heat conductor 210 and the whole tube immersion tank 300. This allows the second transfer rack 430 to simultaneously complete two processes in one movement: removing the heat pipe from the whole tube immersion tank 300 and placing it on the heat conductor 210, and removing the heat pipe from the loading mechanism 600 and placing it into the whole tube immersion tank 300.

[0062] It is conceivable that in other embodiments, the first transfer rack 410 may be movably connected to the base 100 via a guide post and guide sleeve structure, and the second transfer rack 430 may be movably connected to the first transfer rack 410 via a guide post and guide sleeve structure or a slide rail and slider structure; the first transfer driver 420 and the second transfer driver 440 may also be structures such as electric cylinders or hydraulic cylinders.

[0063] It is conceivable that in other embodiments, the material transfer mechanism 400 may also be, for example, a three-axis robotic arm in conjunction with a micro suction cup, to grasp the heat pipe by adsorption and move and transport it.

[0064] In the embodiments, reference is made to Figure 2 The base 100 is provided with a collection mechanism 700 and a feeding mechanism 800. The collection mechanism 700 includes a good product collection box 710 and a defective product collection box 720. The feeding mechanism 800 is used to move the heat pipe located in the heat pipe placement groove 211 to the good product collection box 710 or the defective product collection box 720.

[0065] After the heat pipe's thermal conductivity is tested, it can be determined whether the current heat pipe is a good product or a defective product based on the test results. The heat pipe is then placed into the good product collection box 710 or the defective product collection box 720 by the feeding mechanism 800, which facilitates the subsequent process of taking out good products and recycling defective products.

[0066] In the embodiments, reference is made to Figure 2 The collection mechanism 700 also includes a collection moving frame 730 and a collection driver 740. The good product collection box 710 and the defective product collection box 720 are arranged in the front-to-back direction on the collection moving frame 730. The collection driver 740 is used to drive the collection moving frame 730 to move back and forth. The good product collection box 710 and the defective product collection box 720 are both located on one side of the heat conductor 210 in the left-to-right direction. The unloading mechanism 800 includes an unloading pusher 810 and an unloading driver 820. The unloading pusher 810 is movably arranged in the left-to-right direction on the base 100. The unloading pusher 810 can push the heat pipe into the good product collection box 710 or the defective product collection box 720 along the heat pipe mounting groove 211. The unloading driver 820 is used to drive the unloading pusher 810 to move left and right.

[0067] Specifically, the good product collection box 710 and the defective product collection box 720 are both located on the left side of the heat conductor 210, and the collection moving frame 730 is located on the right side of the good product collection box 710 and the defective product collection box 720.

[0068] After the heat pipe's thermal conductivity is tested, the collection driver 740 moves the collection frame 730 back and forth according to the testing structure, driving the good product collection box 710 or the defective product collection box 720 to move to be roughly opposite the heat conductor 210. Then, the unloading driver 820 drives the unloading pusher 810 to move to the left along the heat pipe placement groove 211, pushing the heat pipe to the left, so that the heat pipe finally detaches from the heat conductor 210 from the left side and enters the good product collection box 710 or the defective product collection box 720, completing the collection and sorting of the heat pipe. The working process is simple and efficient, and the sorting method is relatively simple.

[0069] Specifically, the collecting actuator 740 is a cylinder, the unloading actuator 820 is a cylinder, and the unloading pusher 810 is a pusher pin arranged in the left-right direction. It is conceivable that in other embodiments, the collecting actuator 740 may also be, for example, an electric cylinder or a hydraulic cylinder; the unloading actuator 820 may also be, for example, an electric cylinder or a hydraulic cylinder; and the unloading pusher 810 may also be a push block or a push plate. Those skilled in the art can choose according to actual needs.

[0070] Specifically, inclined guide grooves can be installed on the right side of the good product collection box 710 and the defective product collection box 720 respectively to facilitate the stable entry of the heat pipe into the good product collection box 710 or the defective product collection box 720; or inclined guide grooves can be installed on the heat conductor 210 on the left side to guide the heat pipe into the good product collection box 710 or the defective product collection box 720.

[0071] Specifically, the thermal conductivity testing mechanism 200, the pipe immersion tank 300, the material transfer mechanism 400, the immersion bracket 500, the feeding mechanism 600, the collection mechanism 700, and the unloading mechanism 800 constitute a thermal conductivity testing unit. The base 100 has four testing units arranged in the left and right directions, which facilitates the batch testing of the thermal conductivity of heat pipes and improves production efficiency.

[0072] Specifically, the working process of the heat pipe testing equipment of this utility model is as follows: the staff sends the heat pipes to be tested in batches into the storage hopper 610 of the feeding mechanism 600, and then the feeding driver drives the feeding bracket 620 to lift one of the heat pipes. The transfer mechanism 400 grabs the heat pipe through the pipe clamp 450 on the rear side and moves it into the whole pipe immersion tank 300. The heat pipe is placed on the immersion bracket 500. After immersion, the transfer mechanism 400 grabs the heat pipe through the front pipe clamp 450 and removes it from the whole pipe immersion tank 300. Then, it quickly places both ends of the heat pipe on two heat conductors 210. During this period, the heater heats one of the heat conductors 210. After a period of time, the two temperature sensors 220 respectively sense whether the temperature of both ends of the heat pipe is within the predetermined temperature range. If it is, the heat pipe is a good product; otherwise, the heat pipe is a defective product. Then, the collection driver 740 drives the good product collection box 710 or the defective product collection box 720 to move to be opposite the heat conductor 210. The unloading driver 820 drives the unloading pusher 810 to move to the left, pushing the heat pipe into the corresponding collection box to complete the heat conduction capacity test process of a heat pipe.
