[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] like Figures 1 to 10 As shown, this utility model provides a heat exchange core testing device, comprising: Box 10 has a receiving cavity; At least four partition assemblies 11 are disposed within the receiving cavity and form an installation area for mounting the heat exchange core 12. One end of each partition assembly 11 is fixed to the housing 10, and the other end is used to abut against the heat exchange core 12. The partition assembly 11 includes a first type of partition and a second type of partition. The first type of partition has multiple length specifications, and the second type of partition has multiple length specifications.

[0024] Specifically, the ends of multiple partition assemblies 11 furthest from the housing 10 form an installation area for the heat exchange core 12 in the middle of the housing 10. The heat exchange core 12 can be securely installed by abutting the ends of the partition assemblies 11 furthest from the housing 10 against the heat exchange core 12. Taking four partition assemblies 11 as an example, the housing 10 adopts a square structure, and the four partition assemblies 11 are respectively arranged corresponding to the four side walls of the housing 10. After the heat exchange core 12 is installed, it divides the space inside the cavity into four parts, providing fresh air paths and exhaust air paths. Preferably, the heat exchange core 12 is symmetrically arranged vertically and horizontally with respect to the housing 10. Figure 7-9 From a top-down view, the two partition assemblies 11 arranged opposite each other can adopt the same combination structure to simplify the structural configuration. The two partition assemblies 11 arranged opposite each other are considered as a group, and the two groups of partition assemblies 11 can adopt the same or different combination structures, depending on the shape and size of the heat exchange core 12 to be tested.

[0025] When the two sets of partition assemblies 11 are identical, a combination structure using the same number of first-type and second-type partitions is adopted. When the two sets of partition assemblies 11 are different, a combination structure using different numbers of first-type and second-type partitions is adopted. The length direction of the partition refers to the direction of the line connecting the housing 10 and the heat exchange core 12. The length between the housing 10 and the heat exchange core 12 is predetermined based on the shape and size of the heat exchange core 12 to be tested. The composition of the partition assembly 11 can then be designed based on this length, thereby providing a partition assembly 11 of suitable length to match the installation of the heat exchange core 12.

[0026] The first type of partition and the second type of partition can be partitions of the same shape or partitions of different shapes. In some embodiments, the first type of partition is a square partition 13 and the second type of partition is a V-shaped partition 14. The partition assembly 11 includes at least one square partition 13 and at least one V-shaped partition 14. The number of square partitions 13 and V-shaped partitions 14 can be adjusted according to the actual situation.

[0027] like Figure 4 and Figure 5 As shown, there are two different lengths of square partition 13, with the cross-section of the square partition 13 being either square or rectangular. Figure 6 As shown, one set of opposing sidewalls of the V-shaped partition 14 includes a flat surface and a folded surface. Specifically, the folded surface is provided with a V-shaped groove 141, which can be used to make complementary docking with the corner of the heat exchange core 12.

[0028] In other embodiments, both the first type of partition and the second type of partition are square partitions 13. The partition assembly 11 includes a plurality of square partitions 13 of different lengths. When the heat exchange core 12 is fixed, the plane of the square partition 13 can abut against the plane sidewall and corner of the heat exchange core 12.

[0029] In other embodiments, the first type of partition and the second type of partition may also adopt shapes different from those described above. For example, one of the first type of partition and the second type of partition may have a concave surface and the other may have a convex surface, and they may be spliced ​​together by the complementary concave and convex surfaces.

[0030] In a preferred embodiment of the present invention, the partition assembly 11 includes a square partition 13 and a V-shaped partition 14. The square partition 13 is provided with a through hole 131 opened along its length direction; the V-shaped partition 14 is provided with a threaded hole 15 opened along its length direction.

[0031] like Figures 4 to 6 As shown, when the square partition 13 and the V-shaped partition 14 are spliced ​​together, the connection between the two can be achieved by inserting fasteners through the through hole 131 and the threaded hole 15.

[0032] Of course, it is understandable that in other examples, the square partition 13 and the V-shaped partition 14 can also be connected in other ways, such as by adhesive bonding. The advantage of connecting the square partition 13 and the V-shaped partition 14 with fasteners is that it is easy to disassemble. When the length of the partition assembly 11 formed by splicing is not suitable, it is convenient to disassemble and reselect a suitable partition for splicing. Moreover, the disassembled partitions can be reused multiple times, which can greatly improve the utilization rate of each partition and extend the service life of the structure.

[0033] In some embodiments, the heat exchange core 12 testing device further includes a fixing pin 16, one end of which is used to pass through the through hole 131 and be locked and connected to the threaded hole 15, and the other end of which is locked and fixed to the side wall of the housing 10.

[0034] like Figure 1 As shown, a method for splicing and fixing a partition assembly 11 is provided. By setting a fixing pin 16, not only can the square partition 13 and the V-shaped partition 14 be spliced ​​and fixed, but the partition assembly 11 is also fixed to the housing 10. This reduces the use of installation structures, simplifies the installation process, and facilitates the disassembly of the partition assembly 11. The housing 10 also has threaded holes 15 corresponding to the positions of the partition assembly 11. The fixing pin 16 adopts a double-headed stud structure. The fixing pin 16 can be locked and connected with the threaded hole 15 of the V-shaped partition 14, and passes through the through hole 131 of the square partition 13. Finally, it passes through the side wall of the housing 10, and the fixing pin 16 is locked and fixed on the outside of the housing 10 by a fixing nut 17.

[0035] Furthermore, in order to improve the fixing firmness of the partition assembly 11, the square partition 13 is provided with a plurality of spaced through holes 131 along the height direction, the V-shaped partition 14 is provided with a plurality of spaced threaded holes 15 along the height direction, and the side wall of the box body 10 is also provided with a plurality of spaced threaded holes 15. The partition assembly 11 is fixed along the height direction by a plurality of fixing pins 16, which can make the partition assembly 11 more securely installed.

[0036] It is understandable that when the partition assembly 11 is composed of multiple square partitions 13 of different lengths, some square partitions 13 are provided with through holes 131, and other square partitions 13 are provided with threaded holes 15. The fastening connection between the square partitions 13 can also be achieved by fixing pins 16.

[0037] The heat exchange core testing device of this invention, by adjusting the length of each partition assembly 11, can be applied to the installation and testing of heat exchange cores 12 of various shapes and sizes, offering high flexibility in use. Figure 7As shown, when the heat exchange core 12 has a hexagonal structure, four baffle assemblies 11 are arranged in pairs opposite each other. One set of baffle assemblies 11 includes a square baffle 13 and a V-shaped baffle 14, while the other set of baffle assemblies 11 may only use the square baffle 13. The V-shaped groove 141 of the V-shaped baffle 14 can abut against the corner of the heat exchange core 12, and the plane of the square baffle 13 can abut against the plane sidewall of the heat exchange core 12.

[0038] In another example, such as Figure 8 As shown, the heat exchange core 12 has a quadrilateral structure and a small core size. At this time, the four baffle assemblies 11 can adopt the same combination structure. The baffle assembly 11 includes a square baffle 13 and a V-shaped baffle 14. The baffle assembly 11 is relatively long. The core is fixedly installed by the V-shaped groove 141 of the V-shaped baffle 14 abutting against the corner of the heat exchange core 12.

[0039] In yet another example, such as Figure 9 As shown, the heat exchange core 12 has a quadrilateral structure and a large core size. At this time, the four baffle assemblies 11 can adopt the same combination structure. The baffle assembly 11 includes a square baffle 13 and a V-shaped baffle 14. The baffle assembly 11 is relatively short in length. The core is fixedly installed by the V-shaped groove 141 of the V-shaped baffle 14 abutting against the corner of the heat exchange core 12.

[0040] Based on the above embodiments, as a preferred embodiment of the present invention, the heat exchange core testing device further includes air outlet connectors 18, and four air outlet connectors 18 are arranged in pairs opposite each other on a set of opposite side walls of the housing 10.

[0041] like Figure 1 and Figure 2 As shown, the four air vent connectors 18 serve as indoor air inlets, indoor air outlets, outdoor air inlets, and outdoor air outlets, respectively, to achieve heat and mass exchange between fresh and exhaust air. Specifically, outdoor air flows into the duct through the outdoor air inlet, passes through the heat exchange core 12, and then flows out from the outdoor air outlet. Indoor air flows into the duct through the indoor air inlet, passes through the heat exchange core 12, and then flows out from the indoor air outlet. The housing 10 has mounting openings 101 corresponding to the mounting positions of the air vent connectors 18. The air vent connectors 18 can be installed in the mounting openings 101 by means of screw fixing, threaded connection, welding, etc.

[0042] In some embodiments, such as Figure 2 and Figure 3As shown, the air vent connector 18 is provided with a threaded mounting part 181, which can be threadedly connected to the housing 10. In order to facilitate installation and improve the installation firmness, the air vent connector 18 is also provided with a flange part 182, and the flange part 182 is provided with a positioning hole 183. Correspondingly, the outer wall of the housing 10 is provided with a positioning protrusion 102. When the air vent connector 18 is installed in place, the positioning protrusion 102 is engaged in the positioning hole 183 to limit and prevent loosening.

[0043] In some embodiments, the air vent connector 18 has a first annular connecting portion 184 and a second annular connecting portion 185 at one end protruding from the housing 10, and a transition step 186 is provided between the first annular connecting portion 184 and the second annular connecting portion 185. The outer diameter of the first annular connecting portion 184 is larger than the outer diameter of the second annular connecting portion 185.

[0044] By providing two different sizes of annular connectors, the installation of two different pipe fitting specifications can be accommodated, improving flexibility. Specifically, when the inner diameter of the pipe fitting is smaller, it can be installed by fitting it onto the second annular connector 185, while when the inner diameter of the pipe fitting is larger, it can be installed by fitting it onto the first annular connector 184, further improving the versatility of the device.

[0045] To improve the sealing performance of the device, in some embodiments, a sealing ring is provided between the air outlet connector 18 and the housing 10.

[0046] Specifically, the sealing ring can be fitted onto the threaded mounting portion 181 of the air vent connector 18. When the air vent connector 18 is installed in place, the air vent connector 18 squeezes the sealing ring against the housing 10, improving the sealing between the two and preventing air leakage during the test.

[0047] As a preferred embodiment of the present invention, the heat exchange core testing device further includes an upper cover plate 19 disposed at the upper end of the housing 10 and a lower cover plate disposed at the lower end of the housing 10; both the upper cover plate 19 and the lower cover plate are provided with clearance grooves 20 corresponding to the partition assembly 11.

[0048] like Figure 10 As shown, taking the upper cover plate 19 as an example, when four partition assemblies 11 are provided, the upper cover plate 19 is provided with four corresponding clearance grooves 20. The clearance grooves 20 extend from the edge of the upper cover plate 19 towards the center. The clearance grooves 20 have a suitable length to accommodate various combinations of partition assemblies 11. The width of the clearance grooves 20 is approximately the same as the thickness of the partition assembly 11, facilitating installation through the partition assembly 11. The structure of the lower cover plate is the same as that of the upper cover plate 19, and will not be described again here.

[0049] Furthermore, the upper cover plate 19 and / or the lower cover plate are provided with insulation material on the side facing the heat exchange core 12. By providing insulation material, the sealing and insulation performance of the device can be enhanced, errors during the testing process can be reduced, and the test results can be made more accurate. The insulation material can be applied by pasting or coating it on one side of the upper cover plate 19 and the lower cover plate, or the upper cover plate 19 and the lower cover plate can be made entirely of insulation material.

[0050] Furthermore, the inner side of the enclosure 10 is also provided with insulation material. In order to reduce the weight of the device, the enclosure 10, the upper cover 19, and the lower cover can be made of EPP material, for example.

[0051] Furthermore, in order to improve the sealing performance of the device, a top plate is provided above the upper cover plate 19, i.e. the top of the box 10, and a bottom plate is provided below the lower cover plate, i.e. the bottom of the box 10. The sealing performance of the device is improved by the circumferential sidewalls of the box 10 enclosing the top plate and the bottom plate to form a closed structure.

[0052] The heat exchange core testing device provided by this utility model uses multiple partition assemblies 11 to fix the heat exchange core 12 together. The partition assembly 11 includes a first type of partition and a second type of partition. The first type of partition has multiple length specifications, and the second type of partition has multiple length specifications, so that the overall length of the partition assembly 11 is adjustable. The composition of the partition assembly 11 can be designed according to the shape and size of the heat exchange core 12 to be tested. By using an appropriate number of first type and second type partitions, a length suitable for the heat exchange core 12 to be tested can be formed, thereby meeting the testing requirements of various heat exchange cores 12, improving the versatility of the device, and reducing development costs.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 utility model.
