Description

Technical Field

[0001] This utility model relates to the field of heat-conducting plate testing technology, specifically a VC heat-conducting plate testing device. Background Technology

[0002] VC heat pipe, also known as vacuum chamber heat pipe, is a highly efficient two-dimensional heat dissipation element. Its core structure is a sealed vacuum chamber filled with a small amount of coolant. The inner wall of the chamber has a capillary structure. During operation, the coolant at the heat source evaporates and absorbs heat. The gaseous coolant diffuses rapidly to the low-temperature region in the vacuum environment, condenses and releases heat, and then flows back to the heat source through capillary force, forming a circulation. This can quickly and evenly distribute the heat from local hot spots to the entire plate surface. Compared with the one-dimensional heat conduction of traditional heat pipes, it has a greater advantage in heat dissipation efficiency and is widely used in heat dissipation scenarios of electronic devices.

[0003] Before a VC heat-conducting plate is put into use, it needs to be tested. The core is to verify whether its performance meets the standards and whether it can meet the actual application requirements. After actual testing, its thermal conductivity is confirmed, such as whether the heat from hot spots can be quickly diffused and whether the plate surface temperature is uniform. This is to avoid overheating of the equipment due to insufficient performance and to ensure stable operation throughout the equipment's life cycle.

[0004] Existing testing devices detect heat-conducting plates by heating a portion of the plate and using an infrared thermal imager to capture the temperature distribution across the entire surface. However, this method is simplistic and yields incomplete data. Therefore, a new VC heat-conducting plate testing device is proposed to address these issues. Utility Model Content

[0013] Furthermore, each of the four movable blocks has a limiting slot on its top, through which the heat-conducting plate is placed on the movable block.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 The VC heat-conducting plate testing device in this embodiment includes a testing component 1, a moving component 2, and a control component 3. The moving component 2 is connected to the testing component 1, and the control component 3 is connected to the moving component 2.

[0019] It can be observed that by setting up the active component 2, tests can be performed on heat conduction plates of different sizes, and by setting up the control component 3 and the test component 1, tests can be performed on multiple performance data of the heat conduction plates.

[0020] Test component 1 includes a base 101, a threaded rod 102, a displacement plate 103, a connecting plate 104, and a temperature probe 105. The heating cylinder 305 is fixed to the top of the base 101. The threaded rod 102 is rotatably connected to the right side of the base 101. The displacement plate 103 is threadedly connected to the outer side of the threaded rod 102. The top of the base 101 has a movable opening. The displacement plate 103 is slidably connected to the base 101 through the movable opening. The threaded rod 102 is located inside the movable opening.

[0021] It is understandable that the setting of the movable port is conducive to limiting the displacement plate 103, which in turn facilitates the rotation of the threaded rod 102 to drive the displacement plate 103 to make stable displacement, which is conducive to the adaptation of the heat conduction plate and the improvement of the overall use effect.

[0022] The base 101 has a limiting channel that communicates with the movable opening. The front and rear sides of the displacement plate 103 are slidably connected to the base 101 through the limiting channel. There are two connecting plates 104, one on the left and one on the right. The two connecting plates 104 are fixed to the top of the base 101 and the top of the displacement plate 103, respectively. The temperature probe 105 is fixed to the top of the base 101 and is located directly above the control component 3.

[0023] It should be noted that the setting of the limiting channel helps to further improve the stability of the moving displacement of the displacement plate 103, and helps to improve the overall structural stability.

[0024] Please see Figure 2 To improve flexibility, the movable component 2 in this embodiment includes a movable block 201, a connecting sleeve 202, and a connecting rod 203. The movable block 201 is slidably connected to the groove on the upper part of the connecting plate 104. The movable block 201 is provided with a through hole and an adjustable screw is provided opposite to it. The movable block 201 can be adjusted left and right by tightening or loosening the screw to adapt to the shape of the VC board being tested.

[0025] The connecting sleeve 202 is fixed to the front of the left movable block 201, and the connecting rod 203 is fixed to the front of the right movable block 201. The connecting rod 203 is slidably connected to the inner side of the connecting sleeve 202. The movable component 2 is mirrored on the connecting plate 104 with two sets of front and rear components.

[0026] In actual setup, the mirrored arrangement of the two sets of movable components 2 facilitates the support of the heat-conducting plate by the four movable blocks 201, thereby facilitating the stable positioning of the heat-conducting plate. The displacement of the movable blocks 201 also improves the overall structural flexibility and enhances the effectiveness of the device.

[0027] The fixed plate 301 is fixed to the bottom of the left movable block 201. The connecting plate 104 has a moving channel. The movable block 201 is slidably connected to the connecting plate 104 through the moving channel. The top of each of the four movable blocks 201 has a limiting slot. The heat-conducting plate is placed on the movable block 201 through the limiting slot.

[0028] It should also be noted that the setting of the moving channel facilitates the stable displacement of the movable block 201, and the setting of the limiting slot facilitates the further limiting of the heat-conducting plate, thereby improving the stability of use and the effect of the device. The cooperation of the connecting rod 203 and the connecting sleeve 202 facilitates the linkage of the movable block 201 on one side, thereby improving the ease of use of the device.

[0029] Please see Figure 3To improve the testing effect, the control component 3 in this embodiment includes a fixed plate 301, an electric push rod 302, a resistor block 303, a water cooling head 304, and a heating cylinder 305. The fixed plate 301 is fixedly connected to the movable component 2. The fixed plate 301 is provided with two plates, one at the front and one at the back. An electric push rod 302 is fixed on each of the two fixed plates 301. The resistor block 303 is fixed to the top of the front electric push rod 302, and the water cooling head 304 is fixed to the top of the rear electric push rod 302.

[0030] It is easy to see that the arrangement of the resistor block 303 and the water cooling head 304 facilitates contact between the electric push rod 302 and the heat-conducting plate, thereby enabling the setting of temperature difference on both sides of the heat-conducting plate, improving the diversity of test data, and thus enhancing the test results.

[0031] The heating cylinder 305 is fixedly connected to the test assembly 1. The fixing plate 301 has an L-shaped structure. The heating cylinder 305 is set between two electric push rods 302. The bottom of the resistor block 303 is fixed with a connecting line. The outside of the water cooling head 304 is fixedly connected to a water pipe.

[0032] In actual use, the connection lines and water pipes facilitate the stable use of the resistor block 303 and the water cooling head 304, improving the stability of the device. The heating cylinder 305 positioned between the electric push rods 302 facilitates heating of the central area of ​​the heat-conducting plate, enabling temperature uniformity testing of the heat-conducting plate and improving the test results.

[0033] The working principle of the above embodiments is as follows: A rotating threaded rod 102 is connected to a displacement plate 103 threadedly. Simultaneously, the sliding limit action between the displacement plate 103 and the base 101 allows for left-right adjustment of the threaded rod 102 as it rotates. Furthermore, the sliding connection between the movable block 201 and the connecting plate 104 allows for adjustment of the movable block 201. The sliding limit action between the connecting sleeve 202 and the connecting rod 203 enables the linkage of one side of the movable block 201, thereby adjusting the distance between the four movable blocks 201 to meet the size requirements of different heat-conducting plates. This allows for testing data on the relationship between different heat-conducting plate sizes and thermal conductivity, improving the testing effectiveness of the device. By activating the heating cylinder 305, a region on the heat-conducting plate is heated, and the temperature is detected by the temperature probe 105, thereby achieving a temperature uniformity test of the heat-conducting plate. The heating cylinder 305 is then turned off, and the resistance block 303 is switched on while water circulation within the water-cooling head 304 is initiated. Subsequently, the electric push rod 302 is activated, bringing the resistance block 303 and the water-cooling head 304 into contact with the bottom of the heat-conducting plate, achieving heating at one end and cooling at the other, thus achieving a thermal resistance test of the heat-conducting plate. This further improves the testing effect of the device. The overall device is easy to use and can test heat-conducting plates of different sizes. It can also perform tests on various data related to the heat-conducting plate, improving the device's effectiveness and providing more comprehensive test data.
