The testing of their thermal insulation performance is of great significance for evaluating the building's energy-saving effect. Traditional methods for testing thermal insulation performance mainly employ the steady-state heat flow meter method or the protective hot plate method. However, existing testing devices suffer from problems such as complex structure, cumbersome operation, and low testing accuracy. In particular, thermal bridging effects are easily generated when clamping the specimen, affecting the accuracy of the test results. At the same time, the temperature control system of existing devices has poor stability, and the uniformity of heating and cooling is insufficient, resulting in unstable testing conditions. In addition, the clamping mechanism of existing devices is inconvenient to adjust and cannot adapt to integrated thermal insulation panel specimens of different thicknesses. In other words, the existing technology suffers from technical problems such as low accuracy in testing the thermal insulation performance of integrated thermal insulation panels, unstable testing conditions, and complex operation.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] like Figure 1The diagram shows a structural schematic of a thermal insulation performance testing device for an integrated thermal insulation panel provided by this utility model. The device includes a support frame 1, a heating chamber 2, a cooling chamber 3, a clamping mechanism 4, a temperature sensor group 5, a pressure regulating device 6, and a sealing gasket 7. The support frame 1 supports the entire testing device and provides a stable working platform. The support frame 1 includes a base 11 and a column 12. The base 11 is a rectangular plate structure, welded from steel plates, possessing sufficient strength and rigidity. The column 12 is vertically fixed to the base 11, and the connection is secured by bolts. The heating chamber 2 and the cooling chamber 3 are respectively fixed to the column 12 via support arms 13. The support arms 13 can slide and adjust on the column 12 to accommodate the testing requirements of integrated thermal insulation panel specimens 8 of different sizes. Heating chamber 2 is located on one side of support frame 1. Heating element 21, which is a resistance heating wire 22, is installed inside heating chamber 2. The resistance heating wire 22 is distributed in a serpentine pattern on the inner wall of heating chamber 2 to ensure uniform heating. The resistance heating wire 22 is connected to an external power source via wire 23 for easy temperature control. Cooling chamber 3 is located on the other side of support frame 1, opposite to heating chamber 2. Cooling chamber 3 is equipped with a cooling medium circulation pipeline 31, which includes an inlet pipe 32 and an outlet pipe 33. The inlet pipe 32 and outlet pipe 33 are respectively connected to the side wall of cooling chamber 3. The cooling medium in cooling medium circulation pipeline 31 is circulating water, which is driven by an external water pump to remove heat and achieve a cooling effect. The clamping mechanism 4 is located between the heating box 2 and the cooling box 3 and is used to clamp the integrated insulation plate specimen 8. The clamping mechanism 4 includes a first clamping plate 41 and a second clamping plate 42. The first clamping plate 41 is slidably connected to the second clamping plate 42 through a guide rod 43. The guide rod 43 passes through the guide hole 44 on the second clamping plate 42. There are four guide rods 43, which are arranged in a rectangular shape to ensure the parallel movement of the clamping plate. The length of the guide rod 43 is greater than the maximum travel distance between the first clamping plate 41 and the second clamping plate 42. The inner sides of the first clamping plate 41 and the second clamping plate 42 are respectively provided with clamping grooves 45 that match the shape of the integrated insulation plate specimen 8. Temperature sensor group 5 is respectively installed on the inner wall of heating chamber 2 and cooling chamber 3. Temperature sensor group 5 includes a first temperature sensor 51 and a second temperature sensor 52. The first temperature sensor 51 is installed in the heating chamber 2 near the integrated insulation plate specimen 8, and the second temperature sensor 52 is installed in the cooling chamber 3 near the integrated insulation plate specimen 8. It is used to accurately monitor the temperature on both sides of the integrated insulation plate specimen 8.The pressure regulating device 6 is connected to the clamping mechanism 4. The pressure regulating device 6 includes a screw drive mechanism 61, which includes a screw 62 and a nut 63. One end of the screw 62 is connected to the first clamping plate 41, and the nut 63 is fixed to the support frame 1. The screw 62 passes through the nut 63 and is threaded into it. The other end of the screw 62 is provided with a handle 64. By rotating the handle 64, the clamping force between the first clamping plate 41 and the second clamping plate 42 can be precisely controlled. A sealing gasket 7 is provided on the contact surface between the clamping mechanism 4 and the integrated insulation plate specimen 8. The sealing gasket 7 is made of rubber and has an O-shaped cross-section. The sealing gasket 7 is located around the clamping groove 45 to ensure sealing during the test.

[0034] The method of using this device is as follows: First, place the integrated insulation plate specimen 8 in the clamping groove 45 of the second clamping plate 42. Then, rotate the handle 64 to move the first clamping plate 41 toward the second clamping plate 42 until the sealing gasket 7 is in close contact with the integrated insulation plate specimen 8. Adjust the clamping force to an appropriate value, turn on the power of the heating box 2 to start heating, and at the same time start the circulating water system of the cooling box 3 to start cooling. After the temperature stabilizes, read the temperature values ​​of the heating side and the cooling side through the first temperature sensor 51 and the second temperature sensor 52 respectively. Calculate the thermal conductivity based on the temperature difference and the thickness of the integrated insulation plate specimen 8 to evaluate the insulation performance. After the test is completed, turn off the heating and cooling systems, release the clamping mechanism 4, and take out the integrated insulation plate specimen 8.

[0035] The advantages of this solution compared to existing technologies are as follows: the symmetrical arrangement of the heating chamber 2 and cooling chamber 3 ensures the stability of the temperature gradient; the serpentine distribution of the resistance heating wire 22 and the circulating water cooling system ensure the uniformity of the temperature; the guide rod 43 design of the clamping mechanism 4 ensures the parallel movement of the clamping plate and avoids the tilting deformation of the specimen; the screw drive mechanism 61 realizes the precise control of the clamping force; the sealing gasket 7 effectively prevents heat leakage; the reasonable arrangement of the temperature sensor group 5 ensures the accuracy of temperature measurement; and the entire device has a simple structure, is easy to operate, and has high testing accuracy.

[0036] Based on the above implementation, the following improvements can also be adopted: The heating element 21 of the heating box 2 can be replaced with a hot air circulation heating system. The hot air circulation heating system includes a heater and a fan. The heater heats the air, and the fan drives the hot air to circulate in the heating box 2 to achieve a more uniform heating effect. At the same time, a temperature homogenization device can be added in the cooling box 3. The temperature homogenization device includes a guide plate and a circulating fan. The guide plate guides the flow direction of the cooling medium, and the circulating fan promotes the air flow in the cooling box 3 to make the cooling more uniform. In addition, the guide rod 43 of the clamping mechanism 4 can be replaced with a linear guide rail system. The linear guide rail system includes a guide rail and a slider. The guide rail is fixed on the support frame 1, and the slider is installed on the first clamping plate 41. The slider slides on the guide rail to provide more precise guiding accuracy. A pressure sensor can also be added to the pressure regulating device 6. The pressure sensor is installed on the screw 62 to monitor the magnitude of the clamping force in real time and display the clamping force value through the display device, which is convenient for operators to control precisely.

[0037] The improved solution is similar to the basic solution in its usage, but the differences are as follows: when starting the hot air circulation heating system, it is necessary to preheat for a certain period of time so that the temperature inside the heating chamber 2 reaches the set value before starting the test; when starting the cooling system, the circulating fan needs to be turned on at the same time to ensure the uniformity of the temperature inside the cooling chamber 3; when using the linear guide rail system, the movement of the clamping plate is more stable; when using the pressure sensor, the change of clamping force can be observed in real time through the display device, which is convenient for precise adjustment.

[0038] The improvements of the improved solution compared to the basic solution are as follows: the hot air circulation heating system provides a more uniform heating effect, avoiding local overheating; the temperature homogenization device makes the temperature distribution in the cooling box 3 more uniform, improving the reproducibility of the test; the linear guide rail system provides higher guiding accuracy and reduces the shaking of the clamping plate; and the pressure sensor enables real-time monitoring and precise control of the clamping force. Compared with the existing technology, the improved solution further improves the test accuracy and ease of operation, with more precise temperature control and more stable clamping, providing better technical support for the accurate testing of the insulation performance of the integrated insulation panel.
