It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0028] Embodiment 1:

[0029] like Figure 1-3As shown, a phase change wall thermal performance test device that can be assembled includes an outdoor environment box 1, the interior of the outdoor environment box 1 is fixedly connected to an indoor environment box 2, and the interiors of the outdoor environment box 1 and the indoor environment box 2 are both installed with a temperature measuring device 4 and a temperature regulating device 5. The temperature regulating device 5 inside the outdoor environment box 1 can adjust the temperature inside the outdoor environment box 1 to simulate the outdoor temperature. The temperature measuring device 4 inside the outdoor environment box 1 is used to measure the temperature inside the outdoor environment box 1. The temperature regulating device 5 inside the indoor environment box 2 can adjust the temperature inside the indoor environment box 2 to simulate the indoor temperature. The temperature measuring device 4 inside the indoor environment box 2 is used to measure the temperature inside the indoor environment box 2;

[0030] One end of the indoor environment box 2 is open, and the open end of the indoor environment box 2 is fixedly connected to the phase change wall specimen frame 3 through a connecting structure 17. The phase change wall 22 is installed inside the phase change wall specimen frame 3 to achieve accurate simulation of the actual scene of the phase change wall 22.

[0031] Moreover, the phase change wall specimen frame 3 and the phase change wall 22 are filled with insulation material 14 to ensure sealing, reduce the loss of heat energy through the gap between the phase change wall specimen frame 3 and the phase change wall 22, and improve the detection accuracy.

[0032] Among them, the connecting structure 17 includes a plurality of locking seats 20 and a plurality of clamp locking hooks 21, and the plurality of locking seats 20 are respectively fixedly connected to the peripheral sides of the phase change wall specimen frame 3, and the plurality of clamp locking hooks 21 are respectively fixedly connected to the peripheral sides of the indoor environment box 2, and the plurality of locking seats 20 and the plurality of clamp locking hooks 21 are opposite to each other one by one. During the test, the indoor environment box 2 and the phase change wall specimen frame 3 are fixedly connected by connecting the clamp locking hooks 21 and the locking seats 20, so that the phase change wall specimen frame 3 and the phase change wall 22 can be assembled on the front side of the indoor environment box 2 relatively simply.

[0033] Among them, Figure 1 As shown, the temperature regulating device 5 is installed on the inner wall of the outdoor environmental box 1 or the indoor environmental box 2 to provide cold air and hot air to regulate the temperature.

[0034] Among them, Figure 1 As shown, the number of temperature measuring devices 4 is four. The two temperature measuring devices 4 located inside the outdoor environment box 1 respectively measure the air temperature inside the outdoor environment box 1 and the outer surface temperature of the phase change wall 22. The two temperature measuring devices 4 located inside the indoor environment box 2 respectively measure the air temperature inside the indoor environment box 2 and the inner surface temperature of the phase change wall 22. The temperatures of the phase change wall surface and the indoor environment are measured respectively, thereby improving the accuracy of the thermal performance test results of the phase change wall.

[0035] Among them, Figure 1-2As shown, the temperature measuring device 4 includes a bracket 11 assembled inside the outdoor environmental box 1 or the indoor environmental box 2, and a plurality of temperature sensors 12 are fixedly connected to the bracket 11 through a plurality of nuts 16. The plurality of temperature sensors 12 can be arranged in a rectangular array to ensure the accuracy of the measurement.

[0036] Here, the temperature sensor 12 is a temperature sensor 12 with threads, which is fixed to the bracket 11 through a nut 16. The measurement range of the temperature sensor 12 meets the test temperature variation range.

[0037] The bracket 11 located inside the indoor environmental box 2 can be directly fixedly connected to the interior of the indoor environmental box 2, or can be rotatably connected to the interior of the indoor environmental box 2;

[0038] The bracket 11 located inside the outdoor environment box 1 is preferably rotatably connected to the inside of the outdoor environment box 1, specifically, one end of the bracket 11 is rotatably connected to the inner wall of one side of the outdoor environment box 1, and a horizontally arranged latch movable rod 18 is installed at the other end of the side of the bracket 11. A latch hole 19 is fixedly connected to the side wall on the other side of the outdoor environment box 1. The latch movable rod 18 can be plugged into the latch hole 19 to fix the bracket 11. When the latch movable rod 18 slides out of the latch hole 19, the bracket 11 can be rotated, which is convenient for the user to enter the outdoor environment box 1 to operate the phase change wall specimen frame 3 and the phase change wall 22.

[0039] The distance between the two temperature measuring devices 4 located inside the outdoor environment box 1 is greater than the width of the bracket 11, thereby reducing collisions that occur when the bracket 11 rotates.

[0040] Among them, Figure 1 As shown, the outdoor environment box 1 includes a plurality of polyurethane insulation panels 6, and the plurality of polyurethane insulation panels 6 are fixedly connected by a skeleton frame 7, so that the polyurethane insulation panels 6 and the skeleton frame 7 are assembled into a box body with an opening on the front side, and the front side of the box body is rotatably connected to a door body 13, and a handle 8 is fixedly connected to the outer side of the door body 13. At this time, the user can push the door body 13 by holding the handle 8 to rotate the door body 13, and the door body 13 can be opened and closed relatively simply.

[0041] And, if Figure 1 As shown, a pulley 15 is fixedly connected to the lower side of the phase change wall specimen frame 3, and the pulley 15 can be used to conveniently push the combination of the phase change wall specimen frame 3 and the phase change wall 22. A slope pad 9 is fixedly connected to the lower side of the front side of the box body, and the setting of the slope pad 9 can conveniently push the phase change wall specimen frame 3 into the interior of the outdoor environment box 1, thereby facilitating the installation and disassembly of the phase change wall 22.

[0042] At the same time, a plurality of bases 10 are fixedly connected to the inner wall at the lower side of the outdoor environmental chamber 1, and the indoor environmental chamber 2 is fixedly connected to the upper side of the plurality of bases 10, so that the heights of the indoor environmental chamber 2 and the phase change wall specimen frame 3 can match.

[0043] The working principle of the present invention is:

[0044] When in use, the indoor environmental box 2 is fixed on the upper side of the base 10, and then the phase change wall 22 is pushed to move to the inside of the outdoor environmental box 1 until the front ends of the phase change wall specimen frame 3 and the indoor environmental box 2 are butted against each other, and then the indoor environmental box 2 and the phase change wall specimen frame 3 are tightly fixed together through the connecting structure 17. After the indoor environmental box 2 and the phase change wall specimen frame 3 are connected, the bracket 11 is rotated so that the temperature sensor 12 for measuring the outer surface temperature of the phase change wall 22 inside the outdoor environmental box 1 is in contact with the outer surface of the phase change wall 22;

[0045] At this time, the two temperature measuring devices 4 located inside the outdoor environment box 1 respectively measure the air temperature inside the outdoor environment box 1 and the outer surface temperature of the phase change wall 22, and the two temperature measuring devices 4 located inside the indoor environment box 2 respectively measure the air temperature inside the indoor environment box 2 and the inner surface temperature of the phase change wall 22. By measuring the temperature of the phase change wall surface and the indoor environment respectively, the thermal performance test of the phase change wall 22 can be completed, thereby improving the accuracy of the thermal performance test results of the phase change wall.

[0046] In summary, this technical solution simulates the outdoor environment through the outdoor environment box 1 and simulates the indoor environment through the indoor environment box 2, and can accurately simulate the indoor and outdoor environment of the phase change wall 22. The test temperature is adjustable, the test wall size is controllable, and the test environment is adjustable. It is less restricted by the test temperature, test wall size, and test environment, and can achieve a comprehensive and accurate evaluation of the thermal performance of the phase change wall 22, which better meets the needs of scientific research experiments. In addition, the device is easy to install and operate, has no environmental pollution, and can be widely used in various scientific research sites.

[0049] At this time, after the phase change wall specimen frame 3 is installed on the front side of the indoor environment box 2, the extrusion plate 25 can be started to drive the electric push rod 26 to move toward the direction close to the indoor environment box 2. When the electric push rod 26 moves, it will drive the thermal insulation sealing pad 24 to move together. When the thermal insulation sealing pad 24 and the indoor environment box 2 are against each other, the continuously moving electric push rod 26 will pressurize the thermal insulation sealing pad 24, so that the thermal insulation sealing pad 24 can fill the gap between the indoor environment box 2 and the phase change wall specimen frame 3 to ensure the sealing, reduce the phenomenon of heat energy loss through the gap between the phase change wall specimen frame 3 and the indoor environment box 2, and improve the detection accuracy.
