Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger structure technology, specifically a plate heat exchanger structure. Background Technology
[0002] A plate heat exchanger is a uniquely constructed and highly efficient heat exchanger, consisting of a series of carefully stacked corrugated metal plates. These corrugated metal plates play a crucial role in the operation of the entire heat exchanger, through which heat exchange is achieved.
[0003] In the initial stages of heat exchanger production, efficiency testing is an essential step. To comprehensively and accurately understand the performance of a heat exchanger, its load and thermal efficiency need to be tested. One method used in this testing process is to continuously increase the number of plates. As the number of plates gradually increases, various performance indicators such as the heat exchange situation and load-bearing capacity inside the heat exchanger will change. By carefully observing and accurately measuring these changes, important data on the heat exchanger's efficiency can be obtained.
[0004] Throughout the testing process, the movable plate plays an indispensable role. Due to testing requirements, the movable plate often needs to be moved to clamp and release the plates. This series of operations is crucial for the accuracy and completeness of the test.
[0005] However, large plate heat exchangers present some unique challenges due to the large area and weight of their movable plates. This makes manual movement of the plates extremely inconvenient during operation. Furthermore, replacing the movable plates during use is a complex process. First, the fixing device must be disassembled before the movable plate can be replaced. After the new movable plate is installed, the fixing device must be reinstalled to ensure the heat exchanger functions properly. Utility Model Content

The design of the vents and sealing strips ensures both airtightness and smoother heat exchange. Furthermore, the even placement of the heat exchange plates along the direction of the sealing strips and the design of the clamping plates enhance sealing, reducing heat loss or media leakage to ensure stable heat exchange. Regarding connection and installation, the connecting flanges of the connection device facilitate bolt connection to the air duct. Multiple sealing rings inside the duct enhance sealing, reduce installation difficulty, and improve connection reliability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Please refer to Figure 1 This utility model provides a technical solution: a plate heat exchanger structure, including a main body 1, a connecting device 2 installed on the right side of the main body 1, a positioning rod 3 installed on the left side of the connecting device 2, a heat exchange plate 4 installed on the positioning rod 3, a clamping plate 5 installed on the left side of the heat exchange plate 4, a connecting plate 6 installed on the left side of the clamping plate 5, a rotating shaft 7 installed on the connecting plate 6, a connecting bearing 15 installed on the rotating shaft, a fixing lock 8 installed on the left side of the connecting bearing 15, and a rotating handle 9 installed on the left side of the fixing lock 8.
[0021] The heat exchange plate 4 is provided with an air vent 12, and a sealing strip 11 is installed on the air vent 12. The surface 10 of the heat exchange plate 4 is provided with evenly arranged air vent grooves.
[0022] In this embodiment, the contact area with air or fluid can be greatly increased, which is equivalent to opening more "channels" for the heat exchange process. Air or fluid can have more contact with the heat exchange plate, thus helping to significantly improve heat exchange efficiency.
[0023] The fixed lock 8 includes a lock body 13, on which a lever 14 is installed. The lever 14 can control the opening and closing of the clamps inside the lock body.
[0024] In this embodiment, the lever-controlled opening and closing of the clamp is simple and intuitive. Users can easily operate it without complex training or professional knowledge.
[0025] The heat exchange plates 4 are evenly placed on the left and right sides according to the placement direction of the sealing strips 11, and a whole piece of rubber plate is provided on the side of the clamping plate 5 facing the heat exchange plate 4.
[0026] In this embodiment, while ensuring airtightness, the heat exchange process is also made smoother. There is no leakage, and heat or the medium can pass through efficiently. Furthermore, the heat exchange plates are evenly placed according to the direction of the sealing strips, further improving the overall system's airtightness. With this design, heat loss or medium leakage is greatly reduced, effectively ensuring the stable operation of the heat exchange process.
[0027] The connecting device 2 is equipped with a connecting flange, which can be connected to the air supply duct by bolts, and multiple sealing rings are provided on the inside of the duct.
[0028] In this embodiment, bolt connection to the air supply duct is convenient and robust. The sealing ring inside the duct significantly enhances the seal. This design reduces installation difficulty and improves connection reliability, ensuring the system operates without malfunctions due to connection issues.
[0029] The clamping plate 5 ensures accurate displacement through the positioning rod 3, and rotates the shaft 7 by rotating the handle 9. Through the reaction force with the thread on the connecting bearing 15, the clamping plate 5 is driven to move left and right through the connecting plate 6.
[0030] In this embodiment, the clamping plate uses a positioning rod to ensure accurate displacement, which can effectively reduce possible errors during installation.
[0031] Working principle: In actual use of this equipment, firstly, the handle 9 needs to be rotated to move the clamping plate 5 along the positioning rod 3 until it reaches the lowest position. This provides the basic conditions for the subsequent placement of the heat exchange plate 4.
[0032] Next, the side of the heat exchange plate 4 with the adhesive strip should be placed towards the connecting device 2. It is particularly important to note that the heat exchange plates 4 should be placed evenly, alternating left and right, according to the left-right direction of the adhesive strip. This ensures that the heat exchange plate 4 is subjected to uniform force during subsequent operations and maintains good contact with other components, thereby guaranteeing the efficiency and stability of the entire heat exchange process.
[0033] Then, turn handle 9 again. The rotation of handle 9 will cause the shaft 7 connected to it to rotate. Due to the reaction force between the shaft 7 and the connecting bearing 15, the clamping plate 5 will be moved forward under the action of this reaction force. As the clamping plate 5 moves forward, it will gradually approach the heat exchange plate 4 until it clamps the heat exchange plate 4 tightly.
[0034] After the clamping plate 5 successfully clamps the heat exchange plate 4, the fixing lock 8 needs to be operated. Specifically, the lever 14 is moved to the right, causing the clamping plate inside the fixing lock 8 to clamp. This clamping action securely fixes the rotating shaft 7, preventing it from moving left or right during equipment operation. If the rotating shaft 7 moves left or right, the clamping force of the clamping plate 5 may become unstable, affecting the fixing effect of the heat exchange plate 4 and ultimately adversely impacting the entire heat exchange operation.
[0035] Finally, after completing the preceding series of operations, the entire device can be connected to the ventilation duct via the connecting flange on connecting device 2. Once connected, the device can perform heat exchange operations normally, thereby realizing the heat exchange function and meeting the corresponding usage requirements.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
