Description

Technical Field

[0001] The utility model relates to the technical field of testing instruments, in particular to a thermal performance testing device for green energy-saving building materials. Background Art

[0002] Green energy-saving building materials have excellent thermal properties, which enable them to effectively regulate the ambient temperature within a specific temperature range, reduce the energy consumption of buildings, and have the functions of heat insulation and heat preservation of buildings, as well as the characteristics of reducing the impact on the surrounding environment. Therefore, green energy-saving building materials have been increasingly widely used. In the process of research and development or production of green energy-saving building materials, relevant tests need to be carried out to evaluate the thermal properties of the materials.

[0003] However, due to the lack of dedicated testing equipment, the current testing of green and energy-saving building materials usually places the material samples in a relatively closed heating environment to ensure that they can absorb heat energy. After a period of time, the temperature near the material sample is detected and compared with the ambient heating temperature to evaluate the thermal performance of the material. However, even if the heating environment is relatively closed, heat is still easily transferred to the outside world, causing heat loss, and it is difficult to accurately control the heating conditions. In addition, the instability of the ambient temperature will directly affect the test results, resulting in inaccurate data. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] A thermal performance test device for green energy-saving building materials in this embodiment is shown in the attached Figure 1, including an insulation box 1, a cover body 2, a heating component 3 and a temperature detection component. The cover body 2 is detachably and sealedly connected to the top of the insulation box 1. The heating component 3 is arranged on the cover body 2. The cover body 2 and the insulation box 1 are both made of insulation materials. The insulation box 1 is used to accommodate the test sample 4. The temperature detection component is used to detect the heating temperature of the heating component 3 and the temperature of the top and bottom of the insulation box 1.

[0019] The thermal performance test device of this embodiment can be used to study the temperature control ability of materials when the external temperature changes. When a heat source is provided to the box, the material plays the role of energy storage and heat insulation. By collecting data through the temperature detection component, the temperature at the top and bottom of the insulation box 1 is compared with the temperature at the heating component 3, and the temperature control performance of the material can be evaluated; the insulation box 1 and the cover 2 made of insulation material are used to effectively prevent the loss of heat during transfer, and realize the quantitative study of the energy storage and heat insulation ability of the material. By setting a cover 2 made of the same material on the top of the insulation box 1, and setting a detachable connection between the cover 2 and the insulation box 1, it is convenient to place the test sample 4 before the test and take it out after the test. The sealed connection between the cover 2 and the insulation box 1 can ensure the airtightness between the cover 2 and the insulation box 1 during the test, and further avoid the loss of heat.

[0020] Preferably, the heating component 3 includes a heating lamp 31, and the heating lamp 31 is arranged on the cover 2. The heating lamp 31 is used as a heat source to provide heat to the inside of the incubator 1, which can provide stable and concentrated heat and is easy to control and adjust. The heating lamp 31 is installed on the cover 2 to ensure that heat is evenly transferred from the top to the incubator 1 and fills the entire inner cavity of the incubator 1.

[0021] Furthermore, the heating component 3 also includes a mounting tube 32, which is a blind tube. The top of the mounting tube 32 is a closed end, and the bottom of the mounting tube 32 is an open end. The heating lamp 31 is arranged at the top of the mounting tube 32. The cover 2 is provided with a mounting hole, and the bottom of the mounting tube 32 corresponds to the mounting hole. The mounting tube 32 is connected to the inner cavity of the heat preservation box 1. The mounting tube 32 is used to mount the heating lamp 31 on the cover 2, and the structure is simple, which is convenient for loading and unloading and replacing heating lamps 31 of different powers. The mounting tube 32 with a blind tube structure is adopted, and the heating lamp 31 is installed at the closed end, and the heat-generating end (light-emitting part) of the heating lamp 31 is arranged toward the open end of the mounting tube 32, so as to ensure that the heat generated by the heating lamp 31 is more concentratedly transferred downward, thereby improving the heating efficiency and uniformity.

[0022] Furthermore, the heating component 3 includes a reflective film 33, which covers the inner side of the tube body. By covering the reflective film 33 on the inner side of the tube body, the heat generated by the heating lamp 31 is reflected, so that the heat energy is more concentratedly transferred to the heat preservation box 1, effectively reducing the heat loss inside the tube body, thereby improving the heating efficiency and energy utilization efficiency.

[0023] Preferably, the temperature detection assembly includes a first temperature sensing probe 51, a second temperature sensing probe 52 and a third temperature sensing probe 53. The first temperature sensing probe 51 is arranged in the installation tube 32, and the second temperature sensing probe 52 and the third temperature sensing probe 53 are respectively arranged at the top and the bottom of the heat preservation box 1. The first temperature sensing probe 51 is arranged in the tube body, and is used to detect the temperature of the opening end of the installation tube body 32, so as to obtain the temperature heated by the heating lamp 31; the second temperature sensing probe 52 is arranged at the top of the heat preservation box 1, and is used to detect the temperature of the top of the heat preservation box 1 (i.e., above the test sample 4); the third temperature sensing probe 53 is arranged at the bottom of the heat preservation box 1, and is used to detect the temperature of the bottom of the heat preservation box 1 (i.e., below the test sample 4). Therefore, during the test, the first temperature sensing probe 51, the second temperature sensing probe 52 and the third temperature sensing probe 53 monitor the temperature at the location, so that the temperature changes at the location in different time periods can be obtained, and by comparing the temperature changes at the heating lamp 31 and the top and bottom of the insulation box 1 in different time periods, the temperature control ability of the test sample 4 can be tested, and then the thermal insulation performance of the material can be evaluated.

[0024] Furthermore, a grid 11 is provided in the incubator 1, and the third temperature sensing probe 53 is provided below the grid 11. By providing a horizontal grid 11 in the incubator 1, it can not only be used to support the test sample 4, but also allow the test sample 4 to be suspended in the incubator 1, so that there is enough space below the test sample 4, ensuring that the third temperature sensing probe 53 is in full contact with the heat at the bottom of the test sample 4, thereby ensuring the accuracy of temperature detection. The grid 11 is used so that heat can flow to the bottom of the incubator 1 through the mesh holes on the grid 11, thereby avoiding affecting the detection results. In order to avoid the setting of the grid 11 affecting the test results of the sample, in this embodiment, a grid 11 made of a material with low thermal conductivity can be selected, such as metal materials such as stainless steel and aluminum alloy, or composite materials such as glass fiber.

[0025] Preferably, the cover body 2 and the insulation box 1 are both made of expanded polypropylene (EPP) material, which has good thermal insulation performance, not only helping to reduce heat transfer, thereby maintaining a stable temperature environment during the test and reducing heat loss, but also reducing the total weight of the entire device, making it easier to operate and carry; the mounting tube body 32 is made of polyvinyl chloride (PVC), which has high stability and reliability and low manufacturing cost; the reflective film 33 is made of polyethylene terephthalate (PET), and the PET reflective film 33 has high reflectivity, which can effectively reflect the light and heat emitted by the heating lamp 31 into the insulation box 1, thereby improving the heating efficiency and uniformity, and the reflective film 33 made of PET material has good stability and durability, and can maintain the reflective performance unchanged for a long time in a high temperature environment, thereby extending the service life of the device.

[0026] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
