[0002] In the field of thermal energy engineering, it is crucial to deeply understand and accurately control heat transfer phenomena. As an important form of heat transfer, the experimental research of pool boiling has practical value for the design and calculation of heat transfer equipment such as boilers and evaporators. The research results can also be used to explain the flow boiling phenomenon which is similar to the basic boiling mode but more complex.

[0003] At present, pool boiling experimental devices generally use an integral structural base. However, in some pool boiling experimental studies, it is necessary to pre-weld the experimental surface with an area larger than the cross-sectional area of ​​the heating core to the upper end surface of the heating core before the experiment begins. In this way, the heating core cannot pass through the mounting hole on the base smoothly after welding, which seriously affects the progress and efficiency of the experiment. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present application is to provide a splicing base and a pool boiling experimental device, wherein the splicing base includes a first sealed bottom plate and a second sealed bottom plate that are detachably connected. When conducting a pool boiling experiment, the heating core can be connected to the experimental surface first, and then the base can be installed by splicing. This avoids the problem that the integral structure base cannot be smoothly installed after connecting to the experimental surface because the heating core needs to pass through the mounting hole first. This greatly improves the flexibility and operability of the experiment and effectively guarantees the progress of the experiment.

[0005] In order to solve the above-mentioned problem, the first aspect of the present application provides a splicing base, including a first sealed bottom plate and a second sealed bottom plate, the first sealed bottom plate and the second sealed bottom plate are detachably connected, the surface of the first sealed bottom plate in contact with the second sealed bottom plate is provided with a first yielding portion, and the surface of the second sealed bottom plate in contact with the first sealed bottom plate is provided with a second yielding portion, the first yielding portion and the second yielding portion constitute an installation hole passing through the heating core.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0024] In the present application, unless otherwise clearly specified and defined, the terms "mount", "connect", "couple", "fix", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention.

[0026] See Figure 1 and Figure 2As shown, according to an embodiment of the first aspect of the present application, a splicing base is provided, including a first sealing bottom plate 1 and a second sealing bottom plate 2, the first sealing bottom plate 1 and the second sealing bottom plate 2 are detachably connected, the surface of the first sealing bottom plate 1 that contacts the second sealing bottom plate 2 is provided with a first yielding portion, and the surface of the second sealing bottom plate 2 that contacts the first sealing bottom plate 1 is provided with a second yielding portion, and the first yielding portion and the second yielding portion constitute an installation hole 3 that passes through the heating core.

[0027] It should be noted that in the present application, the first sealing bottom plate 1 and the second sealing bottom plate 2 are detachably connected, making it more flexible when installing the heating core. The heating core can be placed in a suitable position first, and then the base is spliced ​​and installed, which greatly reduces the difficulty of installation and avoids the problem that the integral structure base cannot be smoothly installed after connecting the experimental surface due to the need for the heating core to pass through the mounting hole 3 first, which greatly improves the flexibility and operability of the experiment and effectively guarantees the progress of the experiment. At the same time, in some experiments that require frequent replacement of the heating core, the spliced ​​base can be quickly disassembled and installed, saving experimental preparation time and improving experimental efficiency. At the same time, when a part of the base is damaged, the detachable design makes it possible to replace the first sealing bottom plate 1 or the second sealing bottom plate 2 separately without replacing the entire base, reducing maintenance costs. At the same time, during storage and transportation, the detachable spliced ​​base can take up less space, which is convenient for storage and handling.

[0028] Among them, in the present embodiment, the spliced ​​base is a split structure, which consists of two parts: a first sealing bottom plate 1 and a second sealing bottom plate 2. The first sealing bottom plate 1 and the second sealing bottom plate 2 are made of polyetheretherketone (PEEK). It is understandable that the PEEK material has high strength and rigidity, and can withstand various pressures and stresses in the pool boiling experimental device, ensuring that the base will not be deformed or damaged during use. It also helps to maintain the dimensional stability of the mounting hole 3, ensuring the accurate installation and sealing effect of the heating core. At the same time, PEEK has excellent wear resistance, and can resist the friction and wear of the first sealing bottom plate 1 and the second sealing bottom plate 2 during the experimental operation, thereby extending the service life of the first sealing bottom plate 1 and the second sealing bottom plate 2.

[0029] Specifically, the first sealing bottom plate 1 and the second sealing bottom plate 2 are detachably connected to achieve assembly and disassembly of the spliced ​​base.

[0030] In some specific examples, the first sealing bottom plate 1 and the second sealing bottom plate 2 are matched with each other by any one of bolt connection, snap connection, magnetic connection and plug connection.

[0031] Specifically, when the first sealing bottom plate 1 and the second sealing bottom plate 2 are matched by bolt connection, corresponding screw holes are set at the edges of the first sealing bottom plate 1 and the second sealing bottom plate 2, and the two are fastened together by bolts and nuts; when the first sealing bottom plate 1 and the second sealing bottom plate 2 are matched by snap connection, a protruding snap is set on the first sealing bottom plate 1, and a corresponding snap groove is set on the second sealing bottom plate 2. The connection is achieved by inserting the snap into the snap groove; when the first sealing bottom plate 1 and the second sealing bottom plate 2 are matched by magnetic connection, magnetic materials are respectively embedded in the first sealing bottom plate 1 and the second sealing bottom plate 2, and the two are adsorbed together by magnetic force; when the first sealing bottom plate 1 and the second sealing bottom plate 2 are matched by plug connection, a slot is set on the first sealing bottom plate 1, and a corresponding insert is set on the second sealing bottom plate 2. The connection is achieved by inserting the insert into the slot.

[0032] In this embodiment, the spliced ​​base is applied to the pool boiling experiment device for mounting the heating core. Specifically, the spliced ​​base is provided with a mounting hole 3, and the mounting hole 3 is used to pass the heating core.

[0033] The mounting hole 3 is substantially circular and is composed of a first paving portion and a second paving portion.

[0034] Specifically, the first relief portion may be a first recessed area formed on the surface of the first sealing bottom plate 1 contacting the second sealing bottom plate 2 , and the second relief portion may be a second recessed area formed on the surface of the second sealing bottom plate 2 contacting the first sealing bottom plate 1 .

[0035] The first easing portion and the second easing portion are arranged opposite to each other. When the first sealing bottom plate 1 and the second sealing bottom plate 2 are spliced, the first easing portion on the first sealing bottom plate 1 and the second easing portion on the second sealing bottom plate 2 cooperate with each other to form a mounting hole 3 for the heating core to pass through.

[0036] Specifically, in this embodiment, when the spliced ​​base is applied to the pool boiling experimental device, the installation can be carried out according to the following steps. First, select a suitable heating core according to the experimental requirements and place it in the predetermined experimental position. Next, prepare the first sealed bottom plate 1 and the second sealed bottom plate 2. If a bolt connection is adopted, find the screw holes at the corresponding edges of the first sealed bottom plate 1 and the second sealed bottom plate 2, and use bolts and nuts to fasten the two together; if it is a snap connection, align the raised snap on the first sealed bottom plate 1 with the slot on the second sealed bottom plate 2, and gently push it in so that the snap is inserted into the slot to achieve connection; if it is a magnetic connection, just bring the parts of the first sealed bottom plate 1 and the second sealed bottom plate 2 where the magnetic material is embedded close together and use magnetic force to adsorb them together; and for plug-in connection, align the slot on the first sealed bottom plate 1 with the insert strip on the second sealed bottom plate 2, and insert the insert strip into the slot to complete the connection. During the installation process, it is necessary to ensure that the first sealing bottom plate 1 is tightly fitted with the second sealing bottom plate 2, so that the first clearance portion and the second clearance portion are accurately aligned to form a mounting hole 3 passing through the heating core, thereby achieving a stable installation of the spliced ​​base in the pool boiling experimental device, providing reliable support and a good sealing environment for subsequent experiments.

[0037] In some possible implementations provided in this application, see Figure 2 As shown, a first arcuate groove is provided on the surface of the first clearance portion in contact with the heating core, and a second arcuate groove is provided on the surface of the second clearance portion in contact with the heating core. Sealing rings are provided in the first arcuate groove and the second arcuate groove to form a first sealing structure 4.

[0038] It should be noted that in the present application, a first sealing structure 4 is formed by arranging sealing rings in the first arc groove and the second arc groove, which can effectively prevent liquid or gas from leaking from the contact parts between the first sealing bottom plate 1 and the heating core, and the second sealing bottom plate 2 and the heating core during the experiment, thereby improving the stability and repeatability of the experiment.

[0039] In addition, for the heating core with a variable diameter structure, the first sealing structure 4 can better adapt to its shape change, ensure that a good sealing effect can be achieved at different diameter parts, and improve the compatibility of the spliced ​​base with different types of heating cores. It can be understood that even if the heating core has an unequal diameter structure, the setting of the sealing ring still makes maintenance and replacement relatively easy. When the sealing ring is worn or damaged, it can be replaced in a targeted manner according to the needs of different diameter parts without the need for large-scale disassembly and repair of the entire heating core or base.

[0040] Among them, when the first concession portion is a first recessed area formed by the surface of the first sealing bottom plate 1 contacting the second sealing bottom plate 2, the first arc-shaped groove opened on the surface of the first concession portion contacting the heating core is located at the bottom edge of the first recessed area on the surface contacting the heating core.

[0041] Among them, when the second concession portion is a second recessed area formed by the surface of the second sealing bottom plate 2 that contacts the first sealing bottom plate 1, the second arc groove opened on the surface of the second concession portion that contacts the heating core is located at the bottom edge of the second recessed area on the surface that contacts the heating core.

[0042] Specifically, the vertical cross-sections of the first arc groove and the second arc groove are arc-shaped, which can better match the shape of the sealing ring, so that the sealing ring can fit more tightly in the groove after installation, thereby increasing the reliability of the seal. Secondly, when the arc groove is subjected to pressure, it can evenly distribute the pressure on the sealing ring, thereby avoiding uneven deformation or damage of the sealing ring caused by excessive local pressure. In addition, the arc groove can also provide a certain guiding effect for the sealing ring, ensuring that the sealing ring can accurately enter the groove during the installation process, thereby improving the efficiency and accuracy of the installation.

[0043] The sealing ring may be an O-type sealing ring, etc. In this embodiment, the first arc-shaped groove and the second arc-shaped groove are provided with the same sealing ring.

[0044] Specifically, when the sealing ring is installed in the first arc groove and the second arc groove, and the first sealing bottom plate 1 and the second sealing bottom plate 2 are spliced ​​together, the sealing ring in the first arc groove and the second arc groove and the outer wall of the heating core are squeezed against each other to form a first sealing structure 4.

[0045] Among them, in some specific examples, the sealing ring is made of polytetrafluoroethylene. Polytetrafluoroethylene has extremely high chemical stability and can resist the erosion of various chemical substances in the pool boiling experimental environment. Whether it is acidic, alkaline or organic solvent, it will not cause damage to the sealing ring, ensuring the long-term effectiveness of the sealing structure. The spliced ​​base can be applied to various experimental media, expanding its scope of application and providing more choices for experimenters. At the same time, the polytetrafluoroethylene material has good elasticity and compression resilience, and can fit tightly to the first arc groove and the second arc groove and the surface of the heating core to form a reliable seal. Even in the case of pressure changes or temperature fluctuations, it can maintain good sealing performance. At the same time, the friction coefficient of polytetrafluoroethylene is very low, which makes the sealing ring generate less friction when it contacts the heating core and the spliced ​​bottom plate. On the one hand, it reduces the wear on the heating core and the spliced ​​bottom plate, and prolongs the service life of the experimental device; on the other hand, it also makes installation and disassembly easier, and improves the convenience of operation.

[0046] In some possible implementations provided in this application, see Figure 2 As shown, a first fitting groove is provided on the surface of the first sealing bottom plate 1 in the area outside the first making way portion and in contact with the second sealing bottom plate 2, and a second fitting groove is provided on the surface of the second sealing bottom plate 2 in the area outside the second making way portion and in contact with the first sealing bottom plate 1, and sealing strips are arranged in the first fitting groove and the second fitting groove to form a second sealing structure 5.

[0047] It should be noted that in the present application, in addition to the first sealing structure 4 at the mounting hole 3 formed by the first and second easing parts, the first fitting groove, the second fitting groove and the sealing strip are arranged in the area outside the first and second easing parts to form a second sealing structure 5, providing double sealing protection for the entire spliced ​​base. This greatly reduces the risk of liquid or gas leakage during the experiment, ensures the sealing of the experimental environment, and improves the accuracy of the experimental results.

[0048] Among them, the first fitting groove is located in the area outside the part of the first sealing bottom plate 1 that cooperates with the second sealing bottom plate 2 to form the heating core mounting hole 3, and the second fitting groove is located in the area outside the part of the second sealing bottom plate 2 that cooperates with the first sealing bottom plate 1 to form the heating core mounting hole 3.

[0049] Specifically, on the first sealing bottom plate 1, in the area outside the first concession portion, a first fitting groove is opened on the surface contacting the second sealing bottom plate 2; on the second sealing bottom plate 2, in the area outside the second concession portion, a second wedge-shaped groove is opened on the surface contacting the first sealing bottom plate 1.

[0050] The first fitting groove and the second fitting groove provide installation positions for the sealing strip, ensuring that the sealing strip can be accurately placed between the first sealing bottom plate 1 and the second sealing bottom plate 2 to play a sealing role.

[0051] Specifically, the same sealing strip is arranged in the first fitting groove and the second fitting groove. When the first sealing bottom plate 1 and the second sealing bottom plate 2 are spliced ​​together, the sealing strip is clamped between the first sealing bottom plate 1 and the second sealing bottom plate 2, filling the space between the first fitting groove and the second fitting groove to form a second sealing structure 5. It should be noted that the second sealing structure 5 not only enhances the sealing performance, but also plays a positive role in the structural stability of the entire splicing base. The presence of the sealing strip in the first fitting groove and the second fitting groove increases the tightness of the connection between the first sealing bottom plate 1 and the second sealing bottom plate 2, and reduces the possibility of relative displacement of the first sealing bottom plate 1 and the second sealing bottom plate 2 due to external force or internal pressure changes during the experiment.

[0052] In some specific examples, the cross-section of the sealing strip can be circular, square, D-shaped, etc. When the sealing strip is a circular sealing strip, the first fitting groove and the second fitting groove are semi-circular grooves, and the semi-circular grooves can be closely fitted with half of the circular sealing strip, so that the sealing strip can be uniformly deformed when subjected to pressure; when the sealing strip is a square sealing strip, the first fitting groove and the second fitting groove are rectangular grooves, and the four right-angled sides of the rectangular grooves can fit well with the four sides of the square sealing strip, ensuring that the sealing strip will not move or rotate after installation, thus ensuring the stability of the seal; when the sealing strip is a D-shaped sealing strip, one of the first fitting groove and the second fitting groove is a rectangular groove, and the other is a semi-circular groove, so that the flat part of the D-shaped sealing strip is closely fitted with the flat part of the rectangular groove, while the semi-circular part of the D-shaped sealing strip is adapted to the semi-circular part of the semi-circular groove, ensuring the reliability of the seal.

[0053] In the above embodiment, the sealing strip is made of fluororubber. Fluororubber has excellent chemical corrosion resistance and can resist the erosion of various chemical substances, including acids, alkalis, organic solvents, etc. In the pool boiling experiment, various different chemical media may be contacted, and the fluororubber sealing strip can ensure good sealing performance in these harsh chemical environments and will not be damaged or lose the sealing effect due to chemical corrosion.

[0054] For the embodiments of the second aspect of the present application, see Figure 3 As shown, a pool boiling experiment device is provided, including the spliced base as described above and a boiling chamber 6, and the boiling chamber 6 is buckled on the spliced base.

[0055] Among them, the spliced base provides stable support and sealing functions for the entire pool boiling experiment device. Specifically, the spliced base can firmly install the heating core and ensure that liquid or gas will not leak from the spliced base during the experiment.

[0056] Among them, the boiling chamber 6 is the main place for the pool boiling experiment. In the experiment, the experimental medium is placed in the boiling chamber 6 and heated to the boiling state by the heating core to study the pool boiling phenomenon.

[0057] Specifically, the boiling chamber 6 is located above the spliced base, and one end of the heating core connected to the experimental surface passes through the mounting hole 3 and extends into the boiling chamber 6.

[0058] In some possible embodiments provided by the present application, see Figure 3 As shown, one end of the boiling chamber 6 away from the spliced base is open.

[0059] It should be noted that in this application, one end of the boiling chamber 6 away from the spliced base is open, enabling the experimenter to easily inject the liquid or other media required for the experiment into the boiling chamber 6 without complex operation procedures. This greatly improves the efficiency of experiment preparation, saving time and effort. Meanwhile, during the experiment, it may be necessary to install, replace, or adjust the heating core. The open end provides sufficient space for these operations, allowing the experimenter to operate more conveniently without being restricted by the structure of the boiling chamber 6. At the same time, the experimenter can directly observe the experimental phenomena inside the boiling chamber 6 through the open end, such as the boiling state of the liquid, the formation and movement of bubbles, etc. This helps to understand the progress of the experiment in real time, adjust the experimental parameters in a timely manner, and improve the accuracy and reliability of the experiment.

[0060] Among them, the boiling chamber 6 can be cylindrical, cuboid, etc., for accommodating the experimental medium and conducting pool boiling experiments.

[0061] Specifically, the top of the boiling chamber 6 is open, enabling the experimenter to easily inject the liquid or other media required for the experiment into the boiling chamber 6 without complex operation procedures. This greatly improves the efficiency of experiment preparation, saving time and effort.

[0062] In some possible embodiments provided by this application, as shown in Figure 1 and Figure 3 a card slot is provided on the surface of the spliced base in contact with the boiling chamber 6, and a sealing gasket is arranged in the card slot to form a third sealing structure 7.

[0063] It should be noted that in this application, by providing a card slot and a sealing gasket on the surface of the spliced base in contact with the boiling chamber 6, a sealing defense line is added to the entire pool boiling experimental device. Combined with the previous first sealing structure 4 (the sealing rings in the first arc-shaped groove and the second arc-shaped groove seal the contact part between the heating core and the bottom plate) and the second sealing structure 5 (the sealing strips in the first fitting groove and the second fitting groove seal between the bottom plates), the sealing performance of the device is further improved, effectively preventing the leakage of liquid or gas during the experiment.

[0064] Among them, the card slot can be annular, rectangular, or other shapes.

[0065] Among them, the sealing gasket can be made of materials with elasticity and sealing performance, such as rubber, silica gel, etc.

[0066] Specifically, when the sealing gasket is installed in the card slot, when the sealing gasket is squeezed in the card slot, it will undergo elastic deformation, thus closely fitting between the surface of the spliced base and the boiling chamber 6.

[0067] Those skilled in the art can easily understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

[0068] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application. The above is only the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and variations can be made without departing from the technical principle of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
