Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation testing technology, specifically to a test bench for testing the performance of thermal insulation solutions. Background Technology
[0002] Thermal insulation materials are widely used in solid oxide fuel cell systems, but the effectiveness of insulation structures varies significantly depending on the thickness and material. Chinese utility model patent CN208026663U discloses a high-efficiency coating thermal insulation performance testing device. This device can simultaneously test thermal insulation materials applied to different surfaces of a glass box to obtain the optimal thermal insulation coating formulation and preparation process for use on glass, thus improving testing efficiency. However, this device is not suitable for testing the thermal insulation structure of solid oxide fuel cells. The thermal insulation structure is fixed to the glass box, and the glass box itself has a certain thermal insulation effect, which will affect the test results. If a metal box is used, the thermal conductivity between the surfaces of the metal box will lead to inaccurate test results. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a test bench for testing the performance of thermal insulation solutions. This bench can complete the testing of multiple thermal insulation solutions in one go, saving resources and time, and providing accurate test results.
[0004] To address the aforementioned technical problems, this utility model provides a thermal insulation performance testing bench, comprising a test chamber, a heating element disposed inside the test chamber, a test block mounted on the inner wall of the test chamber, a test hole formed in the wall of the test chamber, a heat-conducting element disposed within the test hole, the side of the heat-conducting element near the inside of the test chamber being used to fit against the test block, and the side of the heat-conducting element near the outside of the test chamber being used to connect a first temperature sensor, the heat-conducting element being fixed within the test hole by a connector, the connector being used to reduce heat conduction from the test chamber to the heat-conducting element.
[0005] In some embodiments, the heat-conducting component, the connector, and the test chamber wall are integrally formed. The test chamber wall has a non-closed hollow groove, the unclosed part of the non-closed hollow groove is the connector, and the inner side of the non-closed hollow groove is the heat-conducting component.
[0006] Furthermore, the non-closed hollow groove is arc-shaped or zigzag-shaped.
[0007] In some embodiments, the connector comprises an inorganic high-temperature adhesive.
[0008] In some embodiments, the heat-conducting element is arranged at the center of the test chamber wall.
[0009] In some embodiments, a base is included, one side of the test chamber is open, the open side of the test chamber is mounted on the base, a heating element is mounted on the base, and one end of the heating element extends into the test chamber.
[0010] In some embodiments, a second temperature sensor is provided on the base, the second temperature sensor being used to measure the temperature inside the test chamber.
[0011] In some embodiments, the test chamber has a polyhedral structure.
[0012] In some embodiments, the test chamber includes n sides, one side having the opening, and the heat-conducting element and test block are disposed on the other n-1 sides.
[0013] In some embodiments, a connecting plate is provided on the open side of the test box, and a connecting hole is provided on the connecting plate. The connecting hole is an oblong hole, and the test box is fixed to the base through the connecting hole.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0024] like Figure 1 As shown, this utility model provides a test bench for testing the performance of a heat insulation scheme, including a test chamber 1, which is a high-temperature resistant metal box. A heating element 2 is installed inside the test chamber 1. The inner wall of the test chamber 1 is used to install a test block 3. Test holes are opened on the wall of the test chamber 1. A heat-conducting element 4 is installed in the test holes. The side of the heat-conducting element 4 near the inside of the test chamber 1 is used to fit with the test block 3. The side of the heat-conducting element 4 near the outside of the test chamber 1 is used to connect a first temperature sensor. The first temperature sensor can be a contact temperature sensor or a non-contact temperature sensor. The heat-conducting element 4 is fixed in the test holes by a connector 5. The connector 5 is used to reduce the heat conduction of the heat-conducting element 4 from the test chamber 1.
[0025] Understandably, multiple test blocks 3 can be installed on different inner walls of the test chamber 1. The interior of the test chamber 1 is heated by the heating element 2. Since the inner side of the heat-conducting element 4 is in contact with the test block 3, the temperature of the heat-conducting element 4 corresponding to different test blocks 3 can be obtained by measuring the temperature of the outer side of the heat-conducting element 4 using the first temperature sensor. This allows for simultaneous testing of different test blocks 3. Each test block 3 can employ different heat insulation schemes, such as variations in material, thickness, or internal structure.
[0026] In some embodiments, such as Figure 2 As shown, the heat-conducting component 4, the connector 5, and the test chamber 1 are integrally formed. The test chamber 1 has a non-closed hollow groove 6 on its wall. The unclosed part of the non-closed hollow groove 6 is the connector 5, and the inner side of the non-closed hollow groove 6 is the heat-conducting component 4.
[0027] Understandably, for performance testing of insulation schemes in solid oxide fuel cell systems, test chamber 1 should be made of high-temperature resistant metal materials. If the temperature of the outer wall of test chamber 1 is directly measured, the temperature difference between each surface of test chamber 1 will be small due to the heat conduction of test chamber 1 itself, making it impossible to test multiple insulation schemes simultaneously. This invention reduces the direct contact area between the heat-conducting component 4 and test chamber 1 by creating non-closed perforated grooves 6 on the wall of test chamber 1, significantly reducing the error caused by heat conduction due to temperature differences between different surfaces of test chamber 1.
[0028] Figure 2 The width of the unclosed part of the non-closed hollow groove 6 is only for illustration. It should be as small as possible while ensuring the fixation of the heat-conducting component 4. That is, the width of the connecting part 5 should be as small as possible to minimize the heat conduction to the heat-conducting component 4.
[0029] Additionally, it should be noted that if this scheme is adopted, the performance test bench for this insulation scheme is suitable for short-term testing, so that the test is completed when the connector 5 has only undergone a small amount of heat conduction.
[0030] Furthermore, the non-closed hollow groove 6 is arc-shaped or zigzag-shaped.
[0031] like Figure 2 As shown, the non-closed hollow groove 6 is arc-shaped, specifically C-shaped. The area enclosed by the C-shape is the heat-conducting component 4. The heat-conducting component 4 is connected to the test chamber 1 through a smaller connector 5, which reduces the influence of temperature differences on different surfaces of the test chamber 1 on the heat-conducting component 4 on different surfaces. In addition, the non-closed hollow groove 6 can also be zigzag-shaped, such as an unclosed quadrilateral or triangle.
[0032] Unlike the connector 5 mentioned above, in some embodiments, the connector 5 includes an inorganic high-temperature adhesive. The inorganic high-temperature adhesive can be arranged around the heat-conducting component 4 in one or half a circle. It is only necessary to ensure a stable connection between the heat-conducting component 4 and the test chamber 1. The inorganic high-temperature adhesive can be ceramic high-temperature adhesive, silicate high-temperature adhesive, or phosphate high-temperature adhesive. Their temperature resistance range all exceed 800°C, which is suitable for testing the heat insulation scheme of high-temperature fuel cells.
[0033] In some embodiments, the heat-conducting component 4 is arranged at the center of the test chamber wall 1, which can ensure the consistency of the test conditions of each heat insulation block and help improve the test accuracy.
[0034] In some embodiments, such as Figure 2 As shown, the thermal insulation performance test bench includes a base 7, one side of the test chamber 1 is open, the open side of the test chamber 1 is installed on the base 7, the heating element 2 is installed on the base 7, and one end of the heating element 2 extends into the test chamber 1.
[0035] The base 7 includes a base plate and a vertical plate 71. The vertical plate 71 is fixed to the base plate by welding or bolts. The heating element 2 is installed on the vertical plate 71. The open side of the test chamber 1 is fixed to the vertical plate 71, so that the heating element 2 is inserted into the test chamber 1.
[0036] In some embodiments, a connecting plate 9 is provided on the open side of the test box 1, and a connecting hole 10 is provided on the connecting plate 9. The connecting hole 10 is an oblong hole, and the test box 1 is fixed to the base 7 through the connecting hole 10.
[0037] Understandably, the oblong hole facilitates the installation of test chambers 1 of different sizes on the upright plate 71. Furthermore, it allows for the adjustment of the heating element 2 to the center of the test chamber 1, further improving testing accuracy.
[0038] In some embodiments, a second temperature sensor 8 is provided on the base 7, which is used to measure the temperature inside the test chamber 1. The second temperature sensor 8 can measure the temperature inside the test chamber 1, which facilitates the comparison of the inner and outer temperatures of the heat insulation block.
[0039] In some embodiments, test box 1 has a polyhedral structure.
[0040] In some embodiments, the test chamber 1 includes n sides, one of which has an opening, and the other n-1 sides are provided with heat-conducting components 4 and test blocks 3.
[0041] like Figure 2 As shown, the test box 1 can be a cube, with test blocks 3 on each of its five faces. The test blocks 3 can be fixed to the test box 1 by bolts or high-temperature adhesive, and the test blocks 3 can be tightly attached to each other for easy installation.
[0042] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
