Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the performance detection of the uniform heating plate, and particularly relates to an angle-adjustable uniform heating plate mass and heat transfer performance detection device. BACKGROUND

[0002] With the continuous progress of science and technology, electronic system-level modules are developing towards miniaturization and light weight to meet the needs of device operation, manufacturing process and consumers. In particular, in the field of mobile electronic products, there is an increasing demand for high-precision, ultra-thin heat dissipation devices. Due to the increasing heat flux density generated by high-end electronic devices, heat dissipation has become one of the main factors leading to the failure of these devices, so higher requirements are placed on efficient heat dissipation solutions. For example, during the operation of a microelectronic chip, almost all the electrical energy input into the semiconductor element is converted into heat; and when an LED is working, about 80% of the electrical energy is also converted into heat. Traditional forced convection cooling methods are difficult to cope with such high heat flux density problems, so it is crucial to research new efficient heat dissipation methods. Currently, phase change heat transfer technology is one of the recognized efficient heat transfer methods, and its application range is wide. Heat pipes and uniform heating plates, as typical representatives of phase change heat transfer technology, have very high equivalent thermal conductivity, far exceeding that of traditional metal materials, and can achieve an efficiency of several tens of times that of traditional heat conduction methods.

[0003] As a passive cooling device, a uniform heating plate achieves heat dissipation function through the circulation phase change (i.e. from liquid to gas and then condenses back to liquid) of the internal working medium, and it is widely used in the heat dissipation of high-speed transmission hard disks, high-performance microprocessors, high-power LED chips, satellite energy conversion components, and medical device radiation elements, etc. due to its light weight, small size, and high thermal conductivity. In the working process of the uniform heating plate, the working medium in the wick absorbs heat from the heat source and undergoes phase change evaporation, the steam fills the entire cavity, and then condenses into liquid at the condensing side, and then returns to the evaporation side under the action of capillary force, completing a cycle of evaporation-condensation-reflow. In order to evaluate the performance of the uniform heating plate, detailed performance detection is needed, which not only helps to judge the quality of the uniform heating plate, but also can further improve its heat transfer performance on the basis of data support. However, most of the existing uniform heating plate test equipment mainly estimates its heat exchange capacity based on the temperature change under steady-state conditions, ignoring the actual situation of the transient temperature change inside the uniform heating plate. This method cannot reflect the process of physical changes inside the uniform heating plate in real time, limiting the understanding and optimization of the dynamic behavior of the uniform heating plate.

[0004] Therefore, it is crucial to develop a test method that can monitor the transient temperature change inside the uniform heating plate in real time for improving the design and performance of the uniform heating plate. UTILITY MODEL CONTENT

[0037] The utility model provides a kind of angle-adjustable heat plate mass transfer heat transfer performance detection device, the device aims at overcoming the limitation of existing heat plate test method, traditional method can only evaluate the performance of heat plate under steady state condition, cannot provide real-time data of internal working medium physical change in its working process.To solve this problem, the device introduces the function of adjustable angle, so that the device can in-depth analyze the working characteristics of heat plate under different inclination angles.

[0038] The angle-adjustable heat plate mass transfer heat transfer performance detection device of the utility model realizes dynamic monitoring of the vaporization, condensation and flow process of the liquid working medium inside the heat plate by integrating a high-speed camera and an infrared detection device, and captures the transient temperature distribution using infrared thermal imaging technology.This combination not only provides intuitive and detailed visual and thermal information, but also helps to gain a deeper understanding of the working mechanism of the heat plate and its influence by various factors, and can comprehensively evaluate its working performance.This will greatly promote the research and development of heat plate technology and accelerate the pace of product improvement and innovation.

[0039] In combination with Figures 1-6The angle-adjustable heat plate mass and heat transfer performance detection device of the embodiment comprises a base 1, an adjustable support 2, a cooling device 3, a laser heating device 4, a clamping device 5, a visual heat plate 6, a motor 7, and a control module 8. The adjustable support 2 is provided with a chain 9 on the periphery. The base 1 is provided with a gear 10 matched with the chain 9. The adjustable support 2 is fixed on the base 1 through the clamping device 5. When working, the control module 8 controls the motor 7 to drive the gear 10 to rotate, and the chain 9 rotates with the gear 10, thereby driving the adjustable support 2 to rotate and realizing the adjustment of the angle of the adjustable support 2.

[0040] In a specific embodiment, in combination Figure 2 The adjustable support 2 is designed in a circular ring structure to provide a stable and uniform support platform, ensuring that the visual heat plate can remain stable during angle adjustment. This circular ring structure not only enhances the mechanical strength of the entire device, but also optimizes the space utilization efficiency, allowing the functional components to be arranged compactly and orderly around it. It is particularly noteworthy that the periphery of the adjustable support 2 is specially designed with a recess 11, which surrounds the entire outer edge of the adjustable support 2 and is used to accommodate and guide the arrangement of the chain 9. The chain 9 is tightly fitted into this recess 11. Through the design of the recess, not only is the deviation or falling off of the chain 9 during operation effectively prevented, but also the smoothness and accuracy of the chain transmission are ensured, thereby achieving precise control of the angle change of the adjustable support 2. In addition, the presence of the recess 11 also provides additional protection for the chain 9, reducing the wear and damage that may be caused by external factors, prolonging the service life of the chain and its transmission system.

[0041] It can be understood that, in order to achieve better results, in combination Figure 2 、 Figure 4 In a specific example, the chain 9 is provided in two, and the gear 10 is provided in four. The two chains are arranged around the periphery of the adjustable support 2, and each chain is matched with two gears. The gears are arranged on the base through a fixing device and can rotate freely. When the performance of the visual heat plate 6 needs to be detected, the motor is controlled through the control module, and the motor drives the gear to rotate through the coupling, thereby driving the adjustable support to rotate and realizing the adjustment of the angle of the heat plate.

[0042] Further, in combination Figure 4, the four gears are divided into two groups, with two gears in each group, arranged on the left and right sides of the base 1. This arrangement aims to ensure that the adjustable support 2 can be adjusted more stably and accurately in angle. By placing the gears 10 on both sides of the base, not only is the force evenly distributed, avoiding the possibility of structural deformation or movement caused by excessive force on one side, but also ensuring the synchronization and stability of the chain transmission. When the motor drives the gears 10 to rotate, the gears on the left and right sides operate synchronously, driving the chain 9 to move uniformly, so that the adjustable support 2 remains balanced during angle adjustment and does not tilt or jam.

[0043] In combination Figure 1 , the adjustable support 2 is equipped with specially designed condensing end clamps 12 and evaporating end clamps 13, which are located at the horizontal axis position of the adjustable support, used to ensure the stability and accuracy of the visualization heat spreader during testing. Specifically, one end of the visualization heat spreader 6 is fixed by the condensing end clamp 12, while the other end is fixed by the evaporating end clamp 13. This design not only ensures that the heat spreader maintains the correct position and angle during the entire experiment, but also provides precise action points for cooling and heating operations.

[0044] The condensing end clamp 12 is designed to effectively cooperate with the cooling device 3. It usually includes one or more condensing holes 14 that are connected to the condensing tube 32 in the cooling device 3, allowing the cooling liquid to directly act on the condensing end of the heat spreader, ensuring efficient condensation.

[0045] The evaporating end clamp 13 is specially designed for laser heating devices. It has a solid structure and good thermal conductivity, which can quickly transfer heat from the laser heating device to the evaporating end of the heat spreader, simulating the heating conditions in the actual working environment. In order to ensure the uniformity and efficiency of heating, the evaporating end clamp 13 may be equipped with reflective materials or thermal insulation layers to reduce unnecessary heat loss and ensure that all heat is effectively utilized in the target area.

[0046] The design of the condensing end clamp 12 and the evaporating end clamp 13 also fully considers the convenience of installation and disassembly. They can be easily adjusted through a quick release mechanism, making it easy to replace visualization heat spreaders of different specifications without affecting the working state of other components. In addition, the material selection and surface treatment of the clamps are carefully considered to ensure durability and reliability during long-term use, while avoiding any potential damage to the heat spreader.

[0047] In combination Figure 2 , Figure 5The cooling device 3 includes a water tank 31 and a condensing pipe 32. The condensing end clamp is provided with a special condensing hole 14, one end of the condensing pipe 31 is connected to the water tank 31, and the other end is in close contact with the visualized heat plate through the condensing hole. This design allows the cooling liquid to circulate, effectively removing heat and achieving efficient condensation of one end of the heat plate. When condensation operation is required, the cooling device is started, and the cooling liquid circulates in the system, rapidly reducing the temperature of a specific area of the heat plate, simulating the condensation process in the actual working environment.

[0048] Again in combination Figure 1 The laser heating device 4 uses a high-precision laser source, and its power and irradiation range can be flexibly adjusted according to experimental requirements. The device is also installed on the adjustable support 2 and is designed to be directly opposite the evaporation end of the visualized heat plate. When heating is required, the laser heating device 4 emits a focused beam that irradiates the target area of the heat plate, providing concentrated heat energy input, which prevents imaging from being blurred due to the large range of heat sources during infrared imaging.

[0049] It can be understood that through the cooperative work of the cooling device 3 and the laser heating device 4, the present application can simulate the heat transfer and mass transfer process of the visualized heat plate under different working conditions. Specifically, when the experiment requires to simulate the condensation stage, the cooling device will start and perform condensation processing; while in the heating stage, the laser heating device is responsible for heating operation. The effective combination of the two devices not only reproduces the actual operating conditions of the heat plate, but also provides valuable experimental data for researchers, which helps to deeply understand the working principle and performance characteristics of the heat plate.

[0050] Again in combination Figure 5 In order to further improve the effect of the cooling device and the laser heating device, a laser heating device mounting rack 16 is specially provided on the adjustable support. The laser heating device mounting rack 16 not only ensures the safe fixation of the equipment. At the same time, the cooling device and the laser heating device are located below the visualized heat plate, which not only facilitates operation but also does not affect the function of other components, and at the same time ensures the efficiency and accuracy of cooling and heating operation.

[0051] Again in combination Figure 1 The adjustable support 2 is also provided with a high-speed camera 17 and an infrared detection device 18. The high-speed camera 17 is used to observe the gasification, condensation and movement of the liquid working medium inside the visualized heat plate in real time, and the infrared detection device 18 is used to observe the temperature change of each part of the visualized heat plate in transient state during operation. The adjustable support 2 is respectively provided with a high-speed camera mounting rack 19 and an infrared detection device mounting rack 20, and the high-speed camera and infrared detection device mounting racks are oppositely arranged.

[0052] In combinationFigure 3 The clamping device 5 comprises a housing 51, a clamping plate 52 slidable along the inner side of the housing, a spring 53 and a pull rod 54; the spring 53 is arranged between the housing 51 and the clamping plate 52, and the pull rod 54 is fixed on the clamping plate 52 through the housing 51; the base 1 is further provided with a baffle 21, and the adjustable support 2 is close to the baffle 21 on one side and close to the clamping plate 52 on the other side; the deformation of the spring 53 is realized by adjusting the pull rod 54 to drive the clamping plate 52 to slide, and the adjustable support 2 is fixed under the joint action of the clamping device 5 and the baffle 21.

[0053] Further, the clamping plate 52 is provided with a reading hole 55, and the reading hole 55 can facilitate the user to observe the reading of the scale line 15 on the adjustable support, so as to record the inclination angle of the visualized heat plate.

[0054] Further, the clamping plate 52 is provided with a reading hole 55, and the reading hole 55 can facilitate the user to observe the reading of the scale line 15 on the adjustable support, so as to record the inclination angle of the visualized heat plate. Figure 1 Figure 7 Further, the clamping plate 52 is provided with a reading hole 55, and the reading hole 55 can facilitate the user to observe the reading of the scale line 15 on the adjustable support, so as to record the inclination angle of the visualized heat plate.

[0055] Further, the clamping plate 52 is provided with a reading hole 55, and the reading hole 55 can facilitate the user to observe the reading of the scale line 15 on the adjustable support, so as to record the inclination angle of the visualized heat plate. Figure 6 When the device is used for performance detection, the control module 8 is connected by the computer 24 of the external device to drive the gear to rotate the adjustable support 2. In this embodiment, the software used by the computer to control the control module is the conventional software in the technical field, and the software part of the utility model has no innovation.

[0056] In a specific embodiment, the visualized heat plate 6 comprises a transparent quartz plate, a copper plate and a wick, the transparent quartz plate is arranged on the copper plate, and the wick is arranged between the transparent quartz plate and the copper plate; the visualized heat plate is fixed by a clamp, the transparent quartz plate faces the high-speed camera, the transparency of the quartz plate enables the high-speed camera to shoot the evaporation, condensation and transmission of the working medium inside the heat plate; the copper plate faces the infrared detection device, and the copper plate has good thermal conductivity, so that the infrared detection device can observe the heat transmission inside the heat plate.

[0057] Based on the structure of the angle-adjustable heat plate mass transfer and heat transfer performance detection device, when performance detection is needed, the following steps are taken:

[0058] S1, when testing, the visualized heat plate 6 is fixed on the visualized support 2 through the condensation end clamp 12 and the evaporation end clamp 13;
