[0045] The following will describe this patent in detail with reference to the drawings.

[0046] Implementation Mode 1

[0047] In the prior art, for the heat insulation test equipment A, the test results of the heat insulation performance of the sample 4 are affected by various factors such as pressure and heat preservation effect. When the heat preservation effect of the equipment does not meet the expectation, situations such as heat dissipation and large deviation in the results of repeated tests may occur, resulting in incorrect measurement of the temperature of the sample 4 after heat insulation. To solve the above problems, the present embodiment provides a heat insulation test equipment A. Specifically, refer to Figure 1 and Figure 6 As shown, the heat insulation test equipment A includes:

[0048] A driving component 3, which is used to move the sample 4 to be tested and apply pressure to the sample 4;

[0049] A heat preservation component 2, which has a cavity 21 for heat preservation;

[0050] A heating component 1, which is arranged in the cavity 21;

[0051] The driving component 3 can push the sample 4 into the cavity 21 so that the sample 4 can cooperate with the cavity 21 to form a heating cavity 24 that encloses the heating component 1 inside.

[0052] As Figure 1 and Figure 6 shown, the heating component 1 is arranged in the cavity 21, and the sample 4 is installed on the driving component 3. The driving component 3 is designed to be able to move along a linear track so as to send the sample 4 into the cavity 21 of the heat preservation component 2. The sample 4 located in the cavity 21 can partition the cavity 21 to form a relatively airtight heating cavity 24; and the heating component 1 located in the cavity 21 is enclosed in the heating cavity 24 by the sample 4. During the heat insulation test, after the heating component 1 is heated to the set temperature, the driving component 3 pushes the sample 4 into the cavity 21 to enclose the heating component 1 in the heating cavity 24, and the temperature changes of the heating cavity 24 and the other side of the sample 4 relative to the heating cavity 24 within a certain period of time are respectively detected, so as to know the heat insulation ability of the sample 4 at a specific temperature.

[0053] During the heat insulation test, the heat preservation component 2 wraps around the periphery of the sample 4, and the cavity 21 in the heat preservation component 2 is partitioned by the sample 4 to form a heating cavity 24. Since the heating cavity 24 is a relatively airtight cavity 21 formed by the sample 4 partitioning the cavity 21 of the heat preservation component 2, the heating component 1 located in the heating cavity 24 can only transfer heat to the other side of the sample 4 through the sample 4, thus ensuring high-precision detection. In addition, the heating cavity 24 is located inside the heat preservation component 2, which means that it is difficult for external heat to enter the heating cavity 24 through the heat preservation component 2, and at the same time, the heat in the heating cavity 24 is also difficult to dissipate to the outside through the heat preservation component 2. This design effectively reduces the influence of external temperature changes on the test results and improves the accuracy and reliability of the detection.

[0054] In this embodiment, the heating component 1 is provided with a temperature detection component for detecting the temperature of the heating component 1. The temperature detection component is arranged near the heating component 1 and can be used to detect the temperature of the heating component 1 and provide signal feedback to the heating component 1 so that the heating component 1 can maintain a specific temperature after heating up. It is worth mentioning that during the heat insulation test, the heating component 1 is in contact with the hot side of the sample 4 (the side of the sample 4 in contact with the heating component 1), and the temperature detection component can simultaneously detect the temperature of the heating component 1 and the hot side of the sample 4 during the heat insulation test.

[0055] Based on the previous embodiment, at least one temperature detection component can also be arranged on the cold side of the sample 4 (the side opposite to the hot side) for detecting the temperature of the cold side of the sample 4 during the heating process, so as to know the heat insulation ability of the sample 4 at a specific temperature in combination with the temperature measured by the temperature detection component on the hot side.

[0056] In an alternative embodiment, multiple temperature detection components can also be arranged on the hot side (the side of the sample 4 in contact with the heating component 1) and the cold side (the side opposite to the hot side) of the sample 4, respectively used to detect the temperatures of different regions, and the average value of the temperatures measured by the temperature detection components in different regions is taken to obtain a more accurate temperature measurement result.

[0057] In some other embodiments, a temperature detection component can also be arranged on the heat preservation component 2. When the sample 4 enters the cavity 21 inside the heat preservation component 2, the temperature detection component is pre-arranged at a position where it can be in contact with the hot side of the sample 4, and the temperature of the hot side of the sample 4 is detected after the sample 4 is sent into the cavity 21.

[0058] The heat insulation test device A arranged as above has the following technical effects:

[0059] 1. The heat preservation component 2 with the cavity 21 can wrap the sample 4, enabling the sample 4 to partition the cavity 21 to form a heating cavity 24 that encloses the heating component 1 inside. The heating component 1 can only transfer heat through the sample 4, thus ensuring high-precision detection.

[0060] 2. The heating cavity 24 is located inside the heat preservation component 2, which means that it is difficult for external heat to enter the heating cavity 24 through the heat preservation component 2, and at the same time, the heat inside the heating cavity 24 is also difficult to dissipate to the outside through the heat preservation component 2. This design effectively reduces the influence of external temperature changes on the test results and improves the accuracy and reliability of the detection.

[0061] Embodiment 2

[0062] This embodiment also discloses a heat insulation test device A. This embodiment further improves the first embodiment. The improvement lies in that the heat insulation component 2 is further disassembled into a heat insulation shell 22 and a heat insulation material 23. Specifically,

[0063] As shown in Figures 1 to 5 the heat insulation component 2 of the heat insulation test device A further includes:

[0064] a heat insulation shell 22, on which an opening 221 is provided, and the opening 221 communicates with the cavity 21;

[0065] a heat insulation material 23, which is arranged inside the heat insulation shell 22, and the heat insulation material 23 can enclose to form a cavity 21.

[0066] The heat insulation shell 22 is a box structure, filled with a heat insulation material 23 inside to form a container with heat insulation function. An opening 221 through which the sample 4 can enter is provided on the heat insulation shell 22, and the opening 221 communicates with the cavity 21 so that the sample 4 can enter the cavity 21 through the opening 221. The heat insulation material 23 is filled inside the heat insulation shell 22, and the heat insulation material 23 can enclose inward along the opening 221 of the heat insulation shell 22 to form the inner wall of the cavity 21. The sample 4 can penetrate into the cavity 21 along the inner wall formed by the heat insulation material 23, and the heat insulation test is carried out under the wrapping of the heat insulation material 23 around the circumferential surface of the sample 4.

[0067] In the heat insulation component 2 arranged as above, the heat insulation material 23 can not only reduce the energy consumption during the heating process of the heating component 1, reduce the production cost, but also reduce the radiation and transfer of heat to the surrounding environment. At the same time, it can also improve the safety of the heat insulation test device A and extend the service life of the device.

[0068] In an alternative embodiment, the heat insulation material 23 can be selected as aluminosilicate needled felt. The temperature range tolerated by aluminosilicate needled felt is generally between 800°C and 1600°C, and it has excellent heat resistance. It has good extensibility, can remain stable at high temperatures, is not easy to deform, and can maintain the stability of the inner wall shape of the enclosed cavity 21; it has good seismic resistance, is white in color and regular in size; aluminosilicate needled felt does not contain any binder, is pure and environmentally friendly.

[0069] In some embodiments, as shown in Figures 3 to 6 the heat insulation material 23 can form a step 231 at the bottom of the cavity 21 so that the four sides of the sample 4 can abut against the step 231 to form a heating cavity 24.

[0070] The heat-insulating material 23 can be shaped at the bottom to form a step 231 around the inner wall of the cavity 21. During the heat-insulation test, after the driving component 3 sends the sample 4 into the cavity 21, the sample 4 can abut against the step 231, and the bottom surface of the sample 4 and the inner side wall of the step 231 can enclose to form a heating cavity 24. Through the arrangement of the step 231, after the sample 4 is sent into the cavity 21, the sample 4 can, under the pressure of the driving component 3, abut against the step 231 to form the heating cavity 24, ensuring the sealing performance of the heating cavity 24, and thus guaranteeing the high precision of the detection.

[0071] In some other embodiments, the heat-insulating material 23 protrudes into the cavity 21 so that the side wall of the cavity 21 formed by the heat-insulating material 23 can abut against the side wall of the sample 4. Specifically, the size of the cavity 21 can be set to be smaller than the size of the sample 4. Thus, on the premise of ensuring that the sample 4 can enter the cavity 21, a part of the structure of the heat-insulating material 23 around the circumferential surface of the cavity 21 abuts against the circumferential surface of the sample 4, assisting the sample 4 to partition the cavity 21 to form a heating cavity 24 with better airtightness. The temperature error in the heating cavity 24 with good airtightness after being heat-insulated by the sample 4 is small and more stable, and the heat-insulating ability of the sample 4 for a specific temperature can be obtained after measurement.

[0072] For example, the heat-insulating material 23 can be selected as aluminosilicate needled felt. The aluminosilicate needled felt is filled inside the heat-insulating shell 22, and the aluminosilicate needled felt makes a part of the circumferential surface around the inner wall protrude inward. The protruding circumferential surface can abut against the circumferential surface of the sample 4 to partition the sample 4.

[0073] Embodiment 3

[0074] This embodiment also discloses a heat-insulation test device A. This embodiment makes a further improvement on the second embodiment. The improvement lies in that the heat-insulating shell 22 is further split into a first shell 222 and a second shell 223, realizing the split disassembly and assembly of the heat-insulating shell 22, facilitating the replacement of the heat-insulating material 23, and reducing the maintenance cost. Specifically, referring to Figure 1 Figure 4 and Figure 5 as shown, the heat-insulating shell 22 of the heat-insulation test device A includes:

[0075] The first shell 222 forms a cavity for accommodating the heat-insulating material 23;

[0076] The second shell 223 is covered on the first shell 222, and the second shell 223 is hollowed out to form an opening 221.

[0077] To facilitate the setting of the thermal insulation material 23, the thermal insulation shell 22 can be further divided into two parts: a first shell 222 and a second shell 223. The first shell 222 and the second shell 223 are installed together in a detachable manner, and the thermal insulation material 23 is arranged between the first shell 222 and the second shell 223.

[0078] The shape of the first shell 222 can be set as a box shape with a box opening. A cavity is formed inside the first shell 222 for arranging the thermal insulation material 23. After the thermal insulation material 23 is arranged inside the first shell 222, the second shell 223 can be covered on the box opening of the first shell 222 to form a coverage of the thermal insulation material 23 exposed at the box opening of the first shell 222.

[0079] The thermal insulation material 23 inside the first shell 222 can enclose a cavity 21 in the middle of the first shell 222, and the cavity 21 can wrap the sample 4. In addition, an opening 221 is formed by hollowing out the second shell 223, and the opening 221 communicates with the cavity 21, so that the sample 4 can enter the inside of the cavity 21 through the opening 221 for heat insulation testing.

[0080] For the thermal insulation shell 22 arranged as above, the thermal insulation material 23 is enclosed by splitting the thermal insulation shell 22 into two parts: the first shell 222 and the second shell 223. When the second shell 223 is not set, the shape of the thermal insulation material 23 can be conveniently adjusted to more easily enclose the cavity 21 structure. In addition, after a long time of heat insulation testing, the thermal insulation material 23 will inevitably be damaged or its heat insulation performance will decrease. After the second shell 223 is removed from the first shell 222, the thermal insulation material 23 can be easily replaced, which can reduce the maintenance cost. At the same time, the shape of the thermal insulation material 23 can be adjusted, and different types of cavities 21 can be changed to adapt to different types of samples 4. In addition, an opening 221 is hollowed out on the second shell 223. When testing samples 4 of different types and different sizes, the second shell 223 can be replaced with another second shell 223 with openings 221 of different sizes to adapt to the size of the sample 4.

[0081] When the heating component 1 is heating, heat will inevitably radiate to the outside through the first shell 222, especially other structural components at the bottom of the first shell 222. In this regard, in some other embodiments, a heat insulation structure can be added at the bottom of the first shell 222 to reduce the influence of the heat radiated by the thermal insulation shell 22 on other part structures. Specifically, as shown in Figure 1 、 Figure 3 and Figure 4 shown, the thermal insulation shell 22 of the heat insulation testing device A further includes a heat insulation board 224, and the first shell 222 is detachably installed on the heat insulation board 224.

[0082] The heat preservation shell 22 may further include a heat preservation board 224 which is arranged at the bottom of the heat preservation shell 22. The first shell 222 is detachably mounted on the heat preservation board 224, and meanwhile, the heat preservation shell 22 can also be replaced. Specifically, the heat preservation board 224 may be arranged at the bottom of the first shell 222, and the planar dimension of the heat preservation board 224 is larger than the dimension of the outer wall of the first shell 222, so that the projection view of the first shell 222 on the heat preservation board 224 can completely fall within the plane of the heat preservation board 224. All of the heat preservation board 224, the first shell 222 and the second shell 223 can be disassembled and replaced to adapt to samples 4 of different types and sizes.

[0083] For example, when a new sample 4 larger than the original sample 4 needs to be detected, the size of the cavity 21 suitable for the original sample 4 will not be suitable for accommodating the new sample 4, and the opening 221 of the first shell 222 is also not suitable for allowing the new sample 4 to pass through. At this time, the first shell 222 and the second shell 223 can be replaced with other components of the same type with different sizes for the new sample 4 to conduct heat insulation tests. When the size of the first shell 222 is larger than that of the heat preservation board 224, the heat preservation board 224 can be replaced simultaneously to set a new first shell 222.

[0084] In addition, the heat preservation board 224 can absorb and insulate a certain amount of heat from the first shell 222 and the heat preservation material 23 to prevent the heat of the first shell 222 and the heat preservation material 23 from diffusing to other components below the heat preservation board 224 and causing heat damage to the components, and can reduce the heat diffusion inside the heat preservation component 2.

[0085] Embodiment 4

[0086] This embodiment also discloses a heat insulation test device A. This embodiment further improves the first, second or third embodiment, and the improvement lies in that at least part of the driving component 3 can extend into the cavity 21.

[0087] As Figure 1 and Figure 2 shown, at least part of the driving component 3 can extend into the cavity 21 inside the heat preservation component 2 together with the sample 4, so that the driving component 3 can close the opening 221 of the cavity 21 to a certain extent, making it difficult for external heat to enter the cavity 21 through the opening 221, and at the same time, it is also difficult for the heat in the cavity 21 to be dissipated to the outside through the opening 221, that is, the heat exchange between the cavity 21 and the outside is reduced, effectively reducing the influence of external temperature changes on the test results and improving the accuracy and reliability of the detection.

[0088] In some embodiments, as Figure 1 and Figure 2 shown, the driving component 3 includes:

[0089] The cold plate assembly 31 is connected to the sample 4 and pushes the sample 4 into the cavity 21;

[0090] The guiding assembly 32 is connected to the cold plate assembly 31 and is used for guiding the movement of the cold plate assembly 31;

[0091] The driving assembly 33 is connected to the cold plate assembly 31 and is used for driving the movement of the cold plate assembly 31.

[0092] The cold plate assembly 31 is used for connecting with the sample 4 and can be driven by the driving assembly 33 to move, so as to push the sample 4 into the cavity 21. Specifically, the cold plate assembly 31 can extend into the cavity 21 to push the sample 4 into the cavity 21 and seal the opening 221 of the cavity 21, reducing the heat exchange between the cavity 21 and the outside world, effectively reducing the influence of the outside temperature change on the test result, and improving the detection accuracy and reliability. In this embodiment, the cold plate assembly 31 has a heat insulation function to prevent the cavity 21 from exchanging heat with the outside world through the cold plate assembly 31, effectively reducing the influence of the outside temperature change on the test result, and improving the detection accuracy and reliability. It should be noted that the cold plate assembly 31 is provided with a temperature detection component for detecting the temperature of the cold plate assembly 31. When the temperature of the cold plate assembly 31 exceeds the rated temperature, the temperature detection component can feedback to the heating component 1 to make it stop heating continuously.

[0093] See Figure 1 and Figure 2 As shown in, the cold plate assembly 31 includes:

[0094] The first cold plate 311 is connected to the driving assembly 33. A cooling component 3111 is arranged on the first cold plate 311, and the first cold plate 311 is used for sealing the opening 221;

[0095] The second cold plate 312 is used for connecting with the sample 4 and can extend into the cavity 21 to push the sample 4 into the cavity 21;

[0096] The third cold plate 313 is arranged between the first cold plate 311 and the second cold plate 312 and is used for heat insulation; both sides of the third cold plate 313 are connected to the first cold plate 311 at intervals through brackets.

[0097] Specifically, the size of the first cold plate 311 is larger than that of the heat insulation component 2, so that, under the push of the driving component 33, the first cold plate 311 covers the upper surface of the heat insulation component 2, thereby closing the opening 221 of the cavity 21 and reducing the heat exchange between the cavity 21 and the outside. In addition, in this embodiment, the first cold plate 311 with a larger size is used, on the one hand, to close the opening 221 of the cavity 21, and on the other hand, it is also connected to the guiding component 32. During the heat insulation test, some heat in the cavity 21 may be transferred to the first cold plate 311, resulting in a large temperature difference of the first cold plate 311 before and after the heat insulation test, and the first cold plate 311 with a larger size is prone to deformation. Therefore, by providing a cooling component 3111 on the first cold plate 311, the cooling component 3111 is used to cool down the first cold plate 311, so that the temperature of the first cold plate 311 can be relatively stable, reducing the temperature difference of the first cold plate 311 before and after the heat insulation test and avoiding the deformation of the first cold plate 311. Specifically, the cooling component 3111 can be a water-cooled elbow pipe, and the water-cooled elbow pipes are arranged in a multi-row winding form on the first cold plate 311.

[0098] In this embodiment, the cold plate assembly 31 may further include a plurality of temperature detection components, and the plurality of temperature detection components are respectively arranged on the first cold plate 311, the second cold plate 312 and the third cold plate 313 to detect the temperatures of the respective cold plates.

[0099] In a preferred embodiment, since the second cold plate 312 is in direct contact with the cold side of the sample 4, the temperature detection component can be arranged on the second cold plate 312, and the temperature of the cold side of the sample 4 can be measured by detecting the temperature of the second cold plate 312. The second cold plate 312 in this embodiment can be made of a material with good thermal conductivity, such as copper, and the thickness can be set thinner to enhance the thermal conductivity of the second cold plate 312, so that the temperature detection component can more accurately detect the temperature of the surface of the sample 4 through the second cold plate 312.

[0100] In a further embodiment, when the temperatures of the first cold plate 311, the second cold plate 312 and / or the third cold plate 313 exceed the rated temperature, the temperature detection component can generate a signal and send it to an alarm to give an alarm, or remind the staff to adjust the equipment through a temperature meter or other means, improving the overall safety of the heat insulation test equipment A.

[0101] Such as Figures 3 to 5As shown, the sizes of the second cold plate 312 and the third cold plate 313 match the opening 221 of the cavity 21, and both can extend into the cavity 21 to further seal the opening 221 of the cavity 21, reducing the heat exchange between the cavity 21 and the outside world, effectively reducing the influence of external temperature changes on the test results, and improving the accuracy and reliability of the detection. In this embodiment, the material of the third cold plate 313 is a heat-insulating material, which can effectively reduce the heat exchange between the cavity 21 and the outside world. In addition, both sides of the third cold plate 313 are connected to the first cold plate 311 through brackets, so that a gap can be formed between the first cold plate 311 and the third cold plate 313, and the two are only connected to each other, which can further reduce the heat transfer.

[0102] In this embodiment, the second cold plate 312 is in direct contact with the sample 4, and the temperature detection component for detecting the other side of the sample 4 relative to the heating cavity 24 can be arranged on the second cold plate 312. In some more preferred embodiments, the second cold plate 312 can be made of a material with a better thermal conductivity, such as copper. The purpose of such a setting is that the second cold plate 312 can better absorb the heat transferred by the heating component 1 through the sample 4 and can play a role in heat homogenization, making the temperature of each area on the other side of the sample 4 relative to the heating cavity 24 uniform, and further making the temperature measured by the temperature detection component for detecting the other side of the sample 4 relative to the heating cavity 24 more accurate, improving the accuracy and reliability of the detection.

[0103] It is worth mentioning that in this embodiment, the side surfaces around the second cold plate 312 and the third cold plate 313 can abut against the side wall of the cavity 21 to better seal the cavity 21 and further reduce the heat exchange between the cavity 21 and the outside world.

[0104] Since the third cold plate 313 is only connected to the first cold plate 311 through brackets on both sides, the driving force of the driving component 33 can only be transmitted through the connection between the two sides of the third cold plate 313, which may cause uneven stress on the third cold plate 313, resulting in deformation of the third cold plate 313 and uneven pressure on the sample 4. In addition, the uneven stress on the sample 4 causes differences in the deformation degrees of different areas of the sample 4, so that there are differences in the heat insulation performance of different areas of the sample 4, which may affect the accuracy and reliability of the detection.

[0105] Therefore, in some preferred embodiments, the cold plate assembly 31 further includes:

[0106] A plurality of struts 314, evenly distributed in the interval between the first cold plate 311 and the third cold plate 313.

[0107] By arranging a plurality of struts 314 evenly distributed between the first cold plate 311 and the third cold plate 313, the driving force of the driving assembly 33 can be transmitted to the third cold plate 313 more evenly, preventing the third cold plate 313 from deforming, and thus ensuring that the sample 4 is uniformly stressed, improving the accuracy and reliability of detection. In addition, in this embodiment, in order to reduce heat transfer, the material of the struts 314 can be a material with a low thermal conductivity, such as polystyrene.

[0108] See Figure 3 As shown, in some other embodiments, in order to further ensure that the sample 4 is uniformly stressed, the strut 314 includes:

[0109] A connecting column 3141, arranged on the first cold plate 311;

[0110] A connecting block 3142, one end of which is threadedly connected to the connecting column 3141, and the other end is rotatably connected to the third cold plate 313.

[0111] With such an arrangement, by rotating the connecting block 3142, through the threaded fit between the connecting block 3142 and the connecting column 3141, the relative position of the connecting block 3142 on the connecting column 3141 can be adjusted, controlling the interval between the third cold plate 313 and the first cold plate 311, so as to adjust the flatness of the third cold plate 313, and thus ensure that the sample 4 is uniformly stressed.

[0112] Finally, it should be noted that those of ordinary skill in the art can understand that in order to enable readers to better understand this patent, many technical details are proposed in the embodiments of this patent. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions required to be protected by the various claims of this patent can be basically achieved. Therefore, in practical applications, various changes can be made to the above embodiments in form and details without departing from the spirit and scope of this patent.
