[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) By using the self-locking cooperation of the fixed square column and the inclined surface of the actuator block, the top plate and the limiting column can be locked by pressing and unlocked by pulling. The replacement time of a single heat exchange core is greatly shortened and no special tools are required. It solves the problem that the traditional heat exchange core frame and core are bonded and welded together and the core cannot be disassembled separately. When replacing, only the damaged heat exchange unit layer or heat exchange positioning module needs to be replaced. The frame can be reused, the cost of use throughout the entire life cycle is reduced, and the economy and maintenance convenience of the product are significantly improved. (2) Through the multi-positioning system of "four corner positioning long slots + inter-layer positioning column holes + upper and lower connecting slots", the stacking coaxiality error of each heat exchange unit layer is controlled within a very small range, so that the cross airflow channels of adjacent layers are precisely aligned and the airflow resistance is reduced; the heat exchange unit layers adopt a 90° orthogonal alternating stacking method to form independent hot and cold fluid channels, realizing efficient heat and humidity transfer; the modular design supports single-layer replacement without the need for overall scrapping of the core, which greatly reduces maintenance costs and material waste; (3) A composite locking structure of “axial locking of inclined block + radial locking of insert block” is adopted. The actuating inclined block is inserted into the actuating inclined groove to achieve axial positioning. The locking insert block is inserted into the locking slot to prevent the actuating slide column from sliding accidentally. The pre-tightening force of the limit spring further increases the friction of the locking contact surface, withstands vibration and impact without loosening, and eliminates the problem of air leakage caused by top plate dislocation and core loosening during equipment operation, which greatly improves the firmness of frame connection and operation safety. (4) Through the synergistic effect of the figure-eight rotating rod and the guide spring, the internal pressure of the heat exchange core is converted into an electrical signal to realize automatic overpressure warning and ensure the accuracy of the warning; at the same time, the pressure plate applies a uniform vertical pre-tightening force to the stacked heat exchange unit layers, so that the bonding gap between each layer is less than a certain range value, thereby eliminating the short circuit phenomenon of airflow between layers and improving the heat exchange efficiency; and it can automatically compensate for the volume change caused by thermal expansion and contraction of the heat exchange unit layers, avoiding core deformation and damage caused by stress concentration.

The positioning plate 9 is attached to the fixed groove 5; the limiting slide plate 9 slides in conjunction with the fixed groove 5; the side of the limiting slide plate 9 near the top plate 3 is located on the moving path of the fixed column 4; the limiting spring 10 is set in the fixed groove 5; one end of the limiting spring 10 is fixedly connected to the bottom surface of the fixed groove 5, and the other end is fixedly connected to the limiting slide plate 9; the positioning long groove 11 is set at the top of the limiting column 2 and extends to its bottom; several positioning long grooves 11 are arranged facing the center direction; the cavity 12 is set in the limiting column 2. The connecting groove 13 is located within the limiting post 2; one side of the connecting groove 13 is connected to the cavity 12, and the other side is connected to the retaining square groove 5; the actuating slide 14 is located on the limiting post 2; one end of the actuating slide 14 is located within the cavity 12, and the other end is located outside the limiting post 2; the actuating slide 14 and the limiting post 2 are in sliding engagement; the actuating inclined block 15 is installed at the end of the actuating slide 14 located within the cavity 12; the inclined surface of the actuating inclined block 15 faces the top plate 3; the initial position of the actuating inclined block 15 is located within the retaining square groove 5; The inclined surface of the movable inclined block 15 is located on the moving path of the fixed column 4; the position of the movable inclined block 15 is higher than that of the limiting slide plate 9; the side of the fixed column 4 is provided with a movable inclined groove 16; the movable inclined groove 16 is located on the moving path of the movable inclined block 15, and the two fit together; a movable spring 17 is sleeved on the movable sliding column 14; one end of the movable spring 17 is fixedly connected to the cavity 12, and the other end is fixedly connected to the movable inclined block 15; the opposing surfaces of the limiting column 2 and the top plate 3 are provided with first contact pieces 18; the two first contact pieces 18 are electrically connected. Heat exchange unit layers 33 are stacked sequentially on the base plate 1. The four corners of the heat exchange unit layer 33 are respectively embedded into the positioning slots 11 of the four limiting posts 2. The layers slide down along the positioning slots 11 to the top of the base plate 1. The positioning posts 35 at the bottom of the heat exchange unit layer 33 are inserted into the connecting slots 36 of the base plate 1 to complete the initial positioning. After all the heat exchange unit layers 33 are stacked, the retaining posts 4 at the bottom of the top plate 3 are aligned with the retaining slots 5 at the top of the limiting posts 2 and pressed vertically downward. The retaining posts 4 slide down along the retaining slots 5. When the side of the retaining posts 4 contacts the inclined surface of the actuating inclined block 15, it will push the actuating inclined block 15 horizontally. The force pushes the actuating inclined block 15 into the cavity 12, causing the actuating slide column 14 to slide outward synchronously, compressing the actuating spring 17; as the retaining column 4 continues to move downward, when its bottom contacts the limiting slide plate 9, it pushes the limiting slide plate 9 downward, compressing the limiting spring 10; when the actuating groove 16 on the side of the retaining column 4 aligns with the actuating inclined block 15, the actuating spring 17 releases its elastic potential energy to push the actuating inclined block 15 into the retaining groove 5, so that the actuating inclined block 15 is precisely locked into the actuating groove 16, completing the axial locking of the retaining column 4; at this time, the bottom surface of the top plate 3 and the top surface of the limiting column 2 are completely in contact, and the two first contact pieces... When contact 18 is established, a signal indicating that the frame assembly is complete is sent to the control system. This completes the assembly, preventing the limit spring 10, which is in a buffer state, from resetting. The resulting elastic force acts on the retaining column 4, thereby increasing the contact friction and strength between the actuating groove 16 and the right-angled surface of the actuating block 15. This prevents the actuating block 15 from dislodging due to non-human factors, improving the installation effect of the core. When the heat exchange core needs to be replaced, simply pull the actuating slide 14 on the four limit columns 2 outwards, causing the actuating block 15 to be pulled out of the actuating groove 16, releasing the lock on the retaining column 4. The limit spring 10 releases its elastic potential energy to push the limit slide plate. 9. Move upwards, thereby causing the fixed column 4 and the top plate 3 to pop up a certain distance, so that the top plate 3 can be easily removed. Then, the stacked heat exchange unit layer 33 can be taken out upwards along the positioning groove 11 for replacement. The entire disassembly and assembly process does not require any special tools such as wrenches or screwdrivers. The replacement time of a single heat exchange core is greatly shortened, which solves the problem that the traditional heat exchange core frame and core integrated structure cannot be disassembled separately. When replacing, only the damaged heat exchange unit layer 33 or the entire heat exchange positioning module needs to be replaced. There is no need to replace the entire frame, which greatly reduces the cost of use and thus significantly improves the economy and maintenance convenience of the product.

[0020] In this embodiment, the limiting post 2 is provided with a redundant locking assembly to prevent the top plate 3 from dislodging after it is fixed. The redundant locking assembly includes a locking base 6, which is installed on the side of the limiting post 2; a locking slot 19, which is disposed through the actuating slide post 14; a locking cylinder 20, which is disposed through the locking base 6; the locking cylinder 20 and the locking base 6 are slidably engaged; a locking horizontal plate 21, which is installed on the locking cylinder 20; a locking insert 22 is installed on the locking horizontal plate 21; the locking insert 22 is engaged with the locking slot 19; and a locking spring 23, which is sleeved on the locking cylinder 20; one end of the locking spring 23 is fixedly connected to the locking horizontal plate 21, and the other end is fixedly connected to the locking base 6. When the actuating slide 14 is pulled outward to disassemble the top plate 3, the locking horizontal plate 21 is pulled upward, causing the locking cylinder 20 and the locking insert 22 to move upward synchronously, compressing the locking spring 23 and causing the locking insert 22 to disengage from the surface of the actuating slide 14. At this time, the actuating slide 14 can slide freely. After the actuating slide 14 moves inward to lock the top plate 3, the locking slot 19 on the actuating slide 14 is exactly aligned with the locking insert 22. When the locking horizontal plate 21 is released, the locking spring 23 releases its elastic potential energy to push the locking horizontal plate 21 downward to reset, causing the locking insert 22 to be precisely inserted into the locking slot 19. The radial locking of the actuator slide column 14 is completed. During equipment operation, even under the action of external forces such as vibration and impact, the locking block 22 can effectively prevent the actuator slide column 14 from sliding outwards unexpectedly, and avoid the actuator inclined block 15 from falling out of the actuator inclined groove 16, which would cause the top plate 3 to dislocate. This forms a double insurance structure of "axial locking of inclined block + radial locking of the locking block". This component adopts a pure mechanical structure, which does not require an additional power source. The structure is simple and reliable, which greatly improves the firmness and safety of the frame connection, and ensures that the heat exchange core will not loosen or leak during long-term operation, thus ensuring the stability of heat exchange efficiency.

[0021] In this embodiment, a pressure control and early warning device is provided on the top plate 3. The pressure control and early warning device includes a pressure square groove 7, which is located on the side of the top plate 3 near the bottom plate 1; a guide groove 8, which is located on the side of the pressure square groove 7; a guide cylinder 24, which is fixedly connected inside the pressure square groove 7; a guide slider 25, which is disposed through the guide cylinder 24; the guide slider 25 and the guide cylinder 24 are slidably engaged; the two guide sliders 25 are symmetrically arranged with the midpoint of the guide cylinder 24 as the center of symmetry; a guide spring 26 is sleeved on the guide cylinder 24; the two ends of the guide spring 26 are fixedly connected to the opposite surfaces of the two guide sliders 25; and a guide horizontal plate 27 is installed on the guide slider 25. 27 is fitted into the guide groove 8, and the two slide together; the opposite surfaces of the guide plate 27 and the guide groove 8 are provided with second contact pieces 28; the two second contact pieces 28 are electrically connected; the first square seat 29 is installed on the guide slider 25 near the bottom plate 1; the rotating rod 30 is movably connected to the first square seat 29; the ends of the two rotating rods 30 away from the first square seat 29 are movably connected to the second square seat 31; the two rotating rods 30 are arranged in a V-shape; the pressure square plate 32 is installed on the second square seat 31 near the bottom plate 1; the initial position of the pressure square plate 32 is located at the bottom of the top plate 3; the maximum movement position of the pressure square plate 32 is located in the pressure square groove 7; After the top plate 3 is installed, the bottom surface of the pressure plate 32 will be tightly attached to the top surface of the uppermost heat exchange unit layer 33, applying a uniform pre-tightening force to the heat exchange unit layer 33, ensuring a tight fit between the heat exchange unit layers 33, eliminating interlayer gaps, and preventing airflow leakage. When the heat exchange unit layer 33 undergoes volume changes due to thermal expansion and contraction, or when the pressure becomes excessive due to excessive stacking layers, the heat exchange unit layer 33 will exert an upward thrust on the pressure plate 32, pushing the pressure plate 32 into the pressure groove 7. The pressure plate 32, through the second seat 31, drives two rotating rods 30 arranged in a figure-eight shape to open and rotate to both sides. The rotating rods 30, through the first seat 29, drive two guide sliders 25 along the guide... The cylinders 24 slide synchronously in opposite directions, stretching the guide spring 26. When the pressure exceeds the preset threshold, the guide slider 25 drives the guide plate 27 to slide along the guide groove 8 to the end, so that the two second contact pieces 28 make contact and conduction, sending an overpressure warning signal to the control system, reminding the staff to check and adjust the stacking state of the heat exchange unit layer 33 in time, so as to avoid deformation and damage of the heat exchange unit layer 33 or cracking of the frame due to excessive pressure. This device can monitor the pressure change inside the heat exchange core in real time, realize automatic overpressure warning, effectively protect the structural integrity of the heat exchange core, and extend its service life. At the same time, the uniform pre-tightening force ensures the sealing performance between each heat exchange unit layer 33, prevents airflow short circuit, and ensures heat exchange efficiency.

[0022] The heat exchange core includes a heat exchange core frame structure and a heat exchange positioning module located between several limiting posts 2. The heat exchange positioning module includes heat exchange unit layers 33. The heat exchange unit layers 33 are corrugated, and several heat exchange unit layers 33 are stacked in an alternating 90° orthogonal manner. The corrugation directions of adjacent heat exchange unit layers 33 are perpendicular to each other, forming two sets of independent cross airflow channels. The top of the heat exchange unit layer 33 is provided with positioning holes 34. The bottom of the heat exchange unit layer 33 is provided with positioning posts 35. When several heat exchange unit layers 33 are stacked, the positioning posts 35 of the upper heat exchange unit layer 33 and the positioning holes 34 of the lower heat exchange unit layer 33 are engaged and inserted into each other. The top of the bottom plate 1 is provided with a connecting groove 36. The connecting groove 36 and the positioning posts 35 are engaged and inserted into each other. The bottom of the top plate 3 is provided with a connecting post 37. The connecting post 37 and the positioning holes 34 are engaged and inserted into each other. The four corners of the heat exchange unit layer 33 are respectively fitted with several positioning long grooves 11, and the two form a sliding fit. When stacking the heat exchange unit layers 33, align the four corners of the first heat exchange unit layer 33 with the positioning slots 11 of the four limiting posts 2, and slide them downwards along the positioning slots 11 so that the positioning posts 35 at the bottom of the first heat exchange unit layer 33 are inserted into the connecting slots 36 of the base plate 1. Then rotate the second heat exchange unit layer 33 by 90° so that its corrugation direction is perpendicular to the first layer, align the positioning posts 35 at the bottom of the second layer with the positioning holes 34 at the top of the first layer and insert them, while the four corners of the second layer slide downwards along the positioning slots 11. Repeat the above operation until all heat exchange unit layers 33 are stacked. Finally, insert the connecting posts 37 at the bottom of the top plate 3 into the positioning holes 34 of the top heat exchange unit layer 33. Through the insertion and engagement of the positioning posts 35 and the positioning holes 34, and the limiting of the four corners of the heat exchange unit layer 33 by the positioning slots 11, the stacking accuracy of each heat exchange unit layer 33 can be guaranteed, and the cross airflow channels between adjacent heat exchange unit layers 33 can be ensured. Precise alignment prevents increased airflow resistance or reduced heat exchange area due to misalignment; the orthogonal alternating stacking method forms independent hot and cold fluid channels, allowing two non-contact fluids to flow crosswise within their respective parallel channels, achieving efficient heat and humidity transfer; when a heat exchange unit layer 33 is damaged, simply remove the top plate 3, remove the heat exchange unit layer 33 above the damaged layer along the positioning groove 11, replace the damaged layer, and re-stack, without replacing the entire core; several heat exchange unit layers 33 can be pre-assembled together, and inserted into the frame for use, significantly reducing core replacement efficiency and improving core installation and usage; at the same time, this module ensures the stacking accuracy and sealing performance of the heat exchange unit layers 33 through a multi-positioning structure, improving heat exchange efficiency, and enabling modular individual replacement of the heat exchange unit layers 33, significantly reducing maintenance costs and extending the overall service life of the heat exchange core.
