[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 and Figure 2 As shown, a phase change material high and low temperature characteristic tester includes: a base frame 1, a chamber 2 is provided on the top of the base frame 1, and support legs are provided below.

[0028] like Figure 3 and Figure 4 As shown, the hopper body 2 is preferably a cylindrical structure, which is arranged on the top of the base frame 1 along the length direction of the base frame 1. The first end of the hopper body 2 is open and the second end is closed, and four compartment-separated sealing plates 3 are slidably arranged inside.

[0029] Preferably, the silo body 2 is fixed to the base frame 1 by support frames 13. There are several support frames 13, which are arranged at intervals along the length of the silo body 2. Their bottoms are fixedly connected to the top of the base frame 1, and their tops surround the outside of the cylindrical silo body 2.

[0030] like Figure 4 and Figure 6 As shown, the compartment split sealing plate 3 is in close contact with the inner wall of the compartment 2 to seal the inner cavity of the compartment 2. The compartment split sealing plate 3 is a circular structure adapted to the cylindrical structure of the compartment 2, and it is in close contact with the inner wall of the compartment 2 to achieve compartmentation. The airtightness of the compartment ensures that liquid entering the compartment will not leak.

[0031] like Figure 5 and Figure 6As shown, the four compartment separate sealing plates 3 are connected as one unit by connecting rods 4, and the two compartment separate sealing plates 3 closest to the first end of the compartment body 2 form the first water level compartment 5, and the two compartment separate sealing plates 3 furthest from the first end of the compartment body 2 form the second water level compartment 6. The first water level compartment 5 and the second water level compartment 6 are of the same length and are arranged at intervals.

[0032] like Figure 5 and Figure 6 As shown, the first water level tank 5 has a water inlet 7 and a drain outlet 8 on the tank split sealing plate 3 at the first end; the second water level tank 6 has a water inlet 7 and a drain outlet 8 on the tank split sealing plate 3 at the second end. The water inlet 7 is used for water to enter the water level tank, and the drain outlet 8 is used for water to drain from the water level tank.

[0033] For example, such as Figure 2 and Figure 3 As shown, in this embodiment, the inlet 7 and outlet 8 of the first water level tank 5 are connected to the water inlet fixed on the protective cover 14 via water supply pipes; the inlet 7 and outlet 8 of the second water level tank 6 are connected to the water inlet fixed at the second end of the tank 2 via water supply pipes. The water inlets can be connected to external equipment via water supply pipes, such as to a drainage pool, a constant temperature water tank, etc.

[0034] A telescopic mechanism 9 is provided on one side of the first end of the compartment 2. The movable end of the telescopic mechanism 9 extends into the interior of the compartment 2 and is fixedly connected to the compartment split sealing plate 3 closest to the first end of the compartment 2, so as to drive the four compartment split sealing plates 3 connected together to move along the compartment 2. Preferably, as follows Figure 5 As shown, the telescopic mechanism 9 is a cylinder, fixed to the base frame 1, with its piston rod extending into the compartment 2 and connecting to the compartment's separate sealing plate 3. Furthermore, a protective cover 14 is provided outside the telescopic mechanism 9 to provide isolation and protection. The protective cover 14 is fixed to the base frame 1, with one end connected to the first end of the compartment 2, thus sealing the first end of the compartment 2.

[0035] like Figure 1 and Figure 2 As shown, the middle part of the chamber 2 is the test chamber 10. The wall thickness of the chamber 2 can be appropriately reduced to improve heat transfer efficiency. The length of the test chamber 10 is equal to that of the first water level chamber 5 and the second water level chamber 6, so that it can be adapted to the test chamber 10 when the first water level chamber 5 or the second water level chamber 6 is moved.

[0036] like Figure 7 As shown, a sample clamp 11 is provided on the test chamber 10 to hold the phase change temperature-regulating fabric covering the test chamber 10. A temperature sensor 12 is located below the test chamber 10, and the temperature sensor 12 is used to monitor the temperature change of the surface of the phase change fabric covering the test chamber 10 in real time. Preferably, there are two temperature sensors 12, symmetrically distributed in the middle of the test chamber 10.

[0037] Optionally, the temperature sensor 12 can be moved closer to or further away from the test chamber 10 via a lifting mechanism to measure the temperature of the fabric covering the test chamber 10. The lifting mechanism is preferably a lifting cylinder, which is housed in the base frame 1, with its piston rod connected to the top of the temperature sensor 12 to move the temperature sensor 12 up or down; alternatively, the temperature sensor 12 can be an infrared temperature sensor, enabling long-distance testing and eliminating the need for a lifting mechanism.

[0038] The sample clamp 11 includes a sample clamp support 111, a lower clamp 112, and an upper clamp 113. There are two sample clamp supports 111, located on top of the two support frames 13 on either side of the test chamber 10. The lower clamp 112 is mounted on the sample clamp support 111. The upper clamp 113 is slidably mounted on the sample clamp support 111, located above the lower clamp 112, and the distance between the upper and lower clamps can be adjusted. The bottom of the upper clamp 113 has a groove that matches the lower clamp 112 to achieve more stable clamping of the phase change fabric.

[0039] Optional, such as Figure 1 and Figure 2 As shown, a protective housing is provided at the second end of the compartment 2. The protective housing is fixed to the base frame 1, covering the second end of the compartment 2 for protection. The protective housing also serves as a support component for the display and control buttons.

[0040] In addition, such as Figure 8 As shown, an isolation cover 16 is provided outside the test chamber 10 to improve the isolation effect and reduce the impact of temperature changes caused by external light sources irradiating the tested fabric on the test.

[0041] The base frame 1 is hollow inside, which facilitates the laying of gas and water pipes.

[0042] Except for test chamber 10, the rest of chamber 2 consists of a two-layer metal structure with a cavity between the two metal walls to ensure temperature stability and prevent condensation from forming on the outside of the cold water chamber.

[0043] Working process: Liquids of different temperatures are introduced into the first water level chamber 5 and the second water level chamber 6 through the water inlet 7; the phase change temperature regulating fabric is placed around the test chamber 10 and covered outside the test chamber 10, and the phase change temperature regulating fabric is fixed by the sample clamp 11; then the telescopic mechanism 9 works to move the first water level chamber 5 and the second water level chamber 6 to the test chamber 10 respectively, so that the liquid inside the first water level chamber 5 or the second water level chamber 6 can conduct heat, changing the temperature of the phase change temperature regulating fabric. The temperature of the phase change temperature regulating fabric is then detected in real time by the temperature sensor 12, and the temperature regulation performance of the phase change temperature regulating fabric is determined by the pattern of temperature change.

[0044] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
