Description

Technical Field

[0001] This utility model relates to the field of sintered layer thermal conductivity testing technology, specifically to a thermal resistance tester for real-time monitoring of the thermal conductivity performance of sintered layers. Background Technology

[0002] The sintered layer thermal conductivity and thermal resistance tester is a specialized device used to evaluate the thermal conductivity and thermal resistance characteristics of sintered materials (such as ceramic substrates, sintered metal powders, and thermal interface materials). Its core function is to accurately measure key parameters such as thermal resistance and thermal conductivity of materials by simulating the heat conduction process under actual working conditions, providing data support for material research and development, process optimization, and quality control.

[0003] Existing thermal resistance testers for real-time monitoring of the thermal conductivity of sintered layers are not convenient for automatic feeding and unloading, nor for uniformly and rapidly heating the sintered layer sample specimens, thus hindering the improvement of testing efficiency. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a real-time monitoring thermal resistance tester for the thermal conductivity of sintered layers. This tester facilitates automatic feeding and discharging, and allows for uniform and rapid heating of sintered layer samples, thereby improving testing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is a thermal resistance tester for real-time monitoring of the thermal conductivity of sintered layers, including an L-shaped support leg, a sealed side plate and a cabinet. The sealed side plate is installed on one side of the cabinet by screws. The sealed side plate is provided with an inlet and outlet on one side, and a sliding plate is inserted into the top of the inlet and outlet through a plug hole. An embedded display screen is embedded on one side of the sealed side plate and above the inlet and outlet. A servo motor is installed on the upper end of the other side of the cabinet through a mounting base. An infrared thermometer is installed through the output shaft of the servo motor through the cabinet by screws.

[0006] The inner wall of the cabinet is equipped with pusher cylinders at both ends via mounting bases, and the output shaft of the pusher cylinders is equipped with a material frame via screws. The bottom of the material frame is provided with a topless shell, and the bottom of the topless shell is equipped with laser heaters at equal intervals via screws. The heating end of the laser heater is located inside the topless shell.

[0007] By adopting the above technical solution, the material frame is automatically pushed out by the electric cylinder, which makes it easy to remove the sintered layer sample specimen. The thermal resistance tester for real-time monitoring of the thermal conductivity of the sintered layer facilitates automatic feeding and discharging, and facilitates uniform and rapid heating of the sintered layer sample specimen, thereby improving testing efficiency.

[0008] Specifically, a heating controller is installed at the bottom of the cabinet by screws, and the output end of the heating controller is electrically connected to the input end of the laser heater by wires.

[0009] Specifically, a servo motor controller is mounted on the lower end of the servo motor by screws, and the output end of the servo motor controller is electrically connected to the input end of the servo motor by wires.

[0010] By adopting the above technical solution, the rotation angle of the servo motor is automatically controlled by the servo motor controller, so that the infrared thermometer rotates to the left and right by a certain angle respectively.

[0011] Specifically, a lever is provided on one side of the top of the slide plate, and sliding grooves corresponding to the slide plate are opened on both sides of the inlet and outlet.

[0012] Specifically, the output terminal of the infrared thermometer and the input terminal of the embedded display screen are electrically connected by wires.

[0013] Specifically, the infrared thermometer is located at the top of the material frame, and the two ends of the topless shell are connected to the cabinet via connecting blocks.

[0014] By adopting the above technical solution, it is easy to install and disassemble the topless shell, and when the sintered layer sample is placed on top of the material frame, it is easy to detect the surface temperature by an infrared thermometer.

[0015] The beneficial effects of this utility model are:

[0016] The sintered layer thermal conductivity real-time monitoring thermal resistance tester of this utility model allows technicians to open the inlet and outlet ports by pulling the slide upwards with a lever. A pusher cylinder automatically pushes the material frame out of the inlet and outlet ports, placing the sintered layer sample specimen on top of the material frame. The pusher cylinder then retracts the material frame and sintered layer sample specimen to their original positions. Sliding the slide downwards closes the inlet and outlet ports. A heating controller automatically controls the laser heater to rapidly heat the sintered layer sample specimen at the top of the material frame. Since multiple laser heaters are provided, uniform heating of the bottom of the sintered layer sample specimen is achieved. An infrared thermometer is used to easily detect the temperature value of the top surface of the sintered layer sample specimen, which is then displayed on an embedded screen, thus revealing the thermal conductivity and thermal resistance performance of the sintered layer sample specimen.

[0017] The thermal resistance tester for real-time monitoring of the thermal conductivity of the sintered layer described in this utility model automatically controls the rotation angle of the servo motor through a servo motor controller, causing the infrared thermometer to rotate a certain angle to the left and right respectively, thereby measuring the temperature at multiple points on the top of the sintered layer sample specimen, improving the final measurement accuracy. After the test is completed, the slide plate on the inlet and outlet is opened, and the material frame is automatically pushed out by the pusher cylinder, making it easy to remove the sintered layer sample specimen.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To facilitate real-time monitoring of the thermal conductivity of the sintered layer, the thermal resistance tester should be equipped with automatic feeding and discharging, ensuring uniform and rapid heating of the sintered layer sample to improve testing efficiency. Figure 1-4 As shown, the sintered layer thermal conductivity real-time monitoring thermal resistance tester of this utility model includes an L-shaped support leg 1, a sealing side plate 4, and a cabinet 7. The sealing side plate 4 is installed on one side of the cabinet 7 by screws. The sealing side plate 4 is provided with an inlet / outlet 2 on one side, and a slide plate 3 is inserted into the top of the inlet / outlet 2 through a plug hole. An embedded display screen 6 is embedded on one side of the sealing side plate 4 and above the inlet / outlet 2. A servo motor 9 is installed on the upper end of the other side of the cabinet 7 through a mounting base. The output shaft of the servo motor 9 passes through the cabinet 7 and an infrared thermometer 14 is installed by screws.

[0026] The inner walls of the cabinet 7 are equipped with pusher cylinders 15 at both ends via mounting bases, and the output shaft of the pusher cylinders 15 is equipped with a material frame 13 via screws. The material frame 13 is provided with a topless shell 12 at its lower end, and laser heaters 11 are installed at equal intervals at the bottom of the topless shell 12 via screws. The heating end of the laser heater 11 is located inside the topless shell 12.

[0027] When in use, the thermal resistance tester for real-time monitoring of the thermal conductivity of the sintered layer facilitates automatic feeding and discharging, and enables uniform and rapid heating of the sintered layer sample specimen, thereby improving testing efficiency.

[0028] For example, such as Figure 1 ,3 As shown, the present invention also includes a heating controller 10 installed on the inner bottom of the cabinet 7 by screws, and the output end of the heating controller 10 is electrically connected to the input end of the laser heater 11 by wires.

[0029] In use, the heating controller 10 automatically controls the laser heater 11 to rapidly heat the sintered layer sample at the top of the material frame 13.

[0030] For example, such as Figure 2 As shown, the present invention also includes a servo motor controller 8 mounted on the lower end of the servo motor 9 by screws, and the output end of the servo motor controller 8 is electrically connected to the input end of the servo motor 9 by wires.

[0031] During use, the rotation angle of the servo motor 9 is automatically controlled by the servo motor controller 8, so that the infrared thermometer 14 rotates to the left and right by a certain angle respectively.

[0032] For example, such as Figure 1 , 4 As shown, the present invention also includes a lever 5 provided on one side of the top of the slide plate 3, and sliding grooves 16 corresponding to the slide plate 3 are provided on both sides of the inlet / outlet port 2.

[0033] When in use, the technician holds the lever 5 and pulls the slide plate 3 upward to open the inlet and outlet ports 2.

[0034] For example, such as Figure 1 , 3 As shown, the present invention also includes an electrical connection between the output terminal of the infrared thermometer 14 and the input terminal of the embedded display screen 6 via a wire.

[0035] In use, the infrared thermometer 14 is used to easily detect the temperature value of the top surface of the sintered layer sample specimen, and the value can be displayed on the embedded display screen 6.

[0036] For example, such as Figure 3 As shown, the present invention also includes an infrared thermometer 14 located at the top of the material frame 13, and the two ends of the topless shell 12 connected to the cabinet 7 via connecting blocks.

[0037] During use, it is easy to install and disassemble the topless shell 12. When the sintered layer sample is placed on top of the material frame 13, the surface temperature can be detected by the infrared thermometer 14.

[0038] When using this utility model, the technician holds the lever 5 and pulls the slide plate 3 upward to open the inlet and outlet port 2. The pusher cylinder 15 automatically pushes the material frame 13 out of the inlet and outlet port 2, places the sintered layer sample specimen on the top of the material frame 13, and drives the material frame 13 and the sintered layer sample specimen to retract and reset through the pusher cylinder 15.

[0039] Slide the slide plate 3 downwards to close the inlet and outlet 2. The heating controller 10 automatically controls the laser heater 11 to quickly heat the sintered layer sample at the top of the material frame 13. Since there are multiple sets of laser heaters 11, the bottom of the sintered layer sample specimen is heated evenly. The infrared thermometer 14 is used to detect the temperature value of the top surface of the sintered layer sample specimen, which can be displayed on the embedded display screen 6 to know the thermal conductivity and thermal resistance performance of the sintered layer sample specimen.

[0040] The servo motor controller 8 automatically controls the rotation angle of the servo motor 9, causing the infrared thermometer 14 to rotate to the left and right by a certain angle, thereby measuring the temperature at multiple points on the top of the sintered layer sample specimen, improving the final measurement accuracy. After the test is completed, the slide plate 3 on the inlet / outlet 2 is opened, and the material frame 13 is automatically pushed out by the pusher cylinder 15, making it easy to remove the sintered layer sample specimen.
