Description

Technical Field

[0001] This utility model belongs to the technical field of thermal conductivity testing devices, and in particular relates to a device for testing the thermal conductivity of composite materials. Background Technology

[0002] Composite materials are multiphase materials prepared by combining two or more materials, such as metals, ceramics, or polymers, through a composite process. The various materials complement each other, creating a synergistic effect that results in composite materials with superior overall performance compared to their constituent materials, thus meeting various requirements. Composite materials consist of a continuous matrix phase and a reinforcing phase phase contained within the matrix. After preparation, the thermal conductivity of composite materials needs to be tested, thus requiring the use of relevant testing equipment.

[0003] Patent document CN217304986U discloses a thermal conductivity testing device for thermally conductive silicone grease, including a base, a lower support plate, a first temperature sensor, an upper support plate, a second temperature sensor, a top plate, guide rods, a test frame, a lower heat-conducting plate, an electric heating plate, an upper heat-conducting plate, a screw sleeve, and a screw. The four guide rods are fixedly installed on the base in a rectangular distribution. The top plate and the lower support plate are fixedly installed on the top and bottom of the guide rods, respectively. The upper support plate is slidably installed on the guide rods.

[0004] During testing, the device can only load the next composite material after the previous one has been removed from the test. Loading and unloading take time, which prevents continuous testing and results in low testing efficiency. Utility Model Content

A tooth 24 is provided on the outer wall of one side of the moving block 22. The motor 25 is fixedly installed on the outer wall of the bottom of the detection base 1, and a gear 26 is provided on the output shaft of the motor 25. The gear 26 meshes with the tooth 24, enabling the two moving bases 21 to move alternately to the bottom of the temperature sensor 8, thereby realizing the continuous thermal conductivity detection function with faster efficiency.

[0029] The top of the movable base 21 is provided with a fixing component 3. The fixing component 3 is symmetrically arranged in two places for clamping the test piece. The fixing component 3 includes a heat-insulating clamping plate 31, a vertical plate 32 and a clamping screw 33. The vertical plate 32 is fixedly installed on the outer wall of the top of the movable base 21. The clamping screw 33 passes through the vertical plate 32 and is threadedly connected to the heat-insulating clamping plate 31. The vertical plate 32 is used to support the clamping screw 33.

The temperature is obtained through temperature sensor 8 and the temperature value is displayed through the connected computer, thereby realizing the detection of thermal conductivity of composite material to be tested.

[0038] When the thermal conductivity of the composite material to be tested is being tested, another movable seat 21 without the composite material to be tested is located on one side of the lifting plate 6, which facilitates loading and eliminates the need to wait for the composite material to be tested to cool down, saving loading and unloading time and making the testing of the composite material more efficient. Then, the motor 25 of another movable component 2 is turned on to drive the gear 26 to rotate and mesh with the teeth 24, which enables the teeth 24 to drive the movable seat 21 that has just been loaded to move, thereby realizing continuous thermal conductivity testing and further improving testing efficiency.
