[0023] 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.

[0024] like Figure 1 As shown, this utility model provides a technical solution: a wall steady-state heat transfer property testing device, including a testing chamber 1, a heating component, a fixing component, and a testing component. A simulated wall is placed flat in the testing chamber 1 and fixed by the fixing component. After the fixing component fixes the simulated wall, the testing chamber 1 is divided into two chambers. The chamber located below the simulated wall is the heating chamber, in which the heating component is installed for heating. The chamber located above the simulated wall is the testing chamber, in which the temperature is detected by the testing component. The testing component includes a cover plate 2, which seals the testing chamber 1 during testing.

[0025] The simulated wall is placed flat in the testing chamber 1 and fixed with fasteners. The fixed simulated wall divides the interior of the testing chamber 1 into a heating chamber and a testing chamber. The heating component is placed in the heating chamber to heat the lower part of the simulated wall. The heat is transferred upward through the simulated wall to the testing chamber. At the same time, the testing component detects the temperature inside the testing chamber. During the test, the cover plate 2 seals the testing chamber 1 to ensure the stability of the testing environment and the accuracy of the data, thereby obtaining the heat transfer performance of the simulated wall under steady-state conditions.

[0026] It can accurately simulate the heat transfer process of walls in actual use, and through precise heating and sealing tests, it can provide reliable experimental data support for the performance evaluation of wall materials and building energy-saving design.

[0027] like Figure 1 and Figure 2As shown, further regarding this scheme, a slot is provided at the bottom of one side of the detection chamber 1, and the heating assembly includes a drawer cover 101. A drawer box 102 is fixed on one side of the drawer cover 101. The drawer box 102 is inserted into the detection chamber 1 through the slot, and a heater 103 is provided inside the drawer box 102 to heat the heating chamber.

[0028] The structure of the drawer cover 101 and drawer box 102 allows the heater 103 to be quickly placed into or removed from the test chamber 1, facilitating the maintenance of the heating components and adjustment of heating parameters. The heater 103 can be an electric heating wire, an infrared heater, a hot air circulation heater, etc., which can more accurately simulate the heat transfer of the wall under different actual heat source environments, thereby improving the accuracy and reliability of the test and providing more accurate data support for the performance evaluation of wall materials.

[0029] Further, a base 104 is fixed to the inner wall of the bottom of the detection chamber 1, and a carrier plate 105 is fixed to the top of the base 104. The simulated wall is placed flat on the carrier plate 105, and the height of the carrier plate 105 is no higher than half the depth of the detection chamber 1.

[0030] This design provides stable support for the simulated wall, ensuring its flatness and stability during the testing process, which helps improve the accuracy of the test. At the same time, the height limitation of the carrier plate 105 ensures that the heating chamber and the testing chamber have sufficient space for heat transfer and temperature detection, making the test results more representative. This structural design is simple and reasonable, easy to operate and maintain, and can effectively improve the efficiency and reliability of the test.

[0031] like Figure 3 As shown, further regarding this scheme, the fastener 3 includes a pressure plate 301, which has a hollowed-out center and its surface contour is adapted to the inner wall contour of the detection chamber 1. The pressure plate 301 is a heat insulation plate.

[0032] The heat insulation design of the pressure plate 301 can effectively reduce the loss of heat to the detection chamber through the inner wall of the detection box 1, and make the heat transfer more concentrated through the simulated wall, thereby improving the accuracy and reliability of the detection. This heat insulation board can be made of materials such as polystyrene foam board, polyurethane foam board, rock wool board, fiberglass board, and aerogel board, which have good heat insulation properties.

[0033] like Figure 3 As shown, further regarding this scheme, side plates 302 are fixed on both sides of the pressure plate 301, and handles 304 are fixed on each side plate 302 for gripping. A buckle strip 303 is also fixed on the side plate 302 facing the inner wall of the detection box 1. A slot 106 is opened at the position of the buckle strip 303 on the detection box 1, and the buckle strip 303 is locked in the slot 106. The cover plate 2 is installed on the top of the detection box 1 by a hinge, and a handle 205 is provided on the cover plate 2 for opening or closing the cover plate 2.

[0034] The engagement of the buckle strip 303 and the bayonet 106 facilitates the installation and removal of the fastener 3, while the handle 304 allows operators to easily grip the fastener 3 for installation or removal, improving testing efficiency. The cover plate 2 is hinged and equipped with a handle 205, enabling quick sealing of the testing chamber 1 during testing, ensuring a stable testing environment and improving testing accuracy. This design simplifies the operation of the entire testing equipment, enhancing both convenience and efficiency.

[0035] like Figure 1 and Figure 2 As shown, further regarding this scheme, the detection component also includes a screw connector 201 located in the middle of the cover plate 2. A screw block 202 is screwed into the middle of the screw connector 201, and a thermometer 203 is fixed in the middle of the screw block 202. The detection end of the thermometer 203 passes through the screw block 202 and is located inside the detection box 1. A pad 204 is also provided at the detection end of the thermometer 203 to contact the simulated wall. Rotating the screw block 202 adjusts the detection of the thermometer detection end against the simulated wall.

[0036] The engagement of the screw connector 201 and the screw block 202 allows for flexible adjustment of the thermometer 203's position, accommodating simulated walls of varying thicknesses. This ensures close contact between the thermometer 203's sensing end and the simulated wall, improving temperature detection accuracy. The spacer 204 protects the simulated wall surface from damage while maintaining good thermal contact, further enhancing detection precision. The spacer 204 can be made of highly thermally conductive materials such as copper or silicone rubber, providing excellent and stable heat conduction for the thermometer to detect.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
