Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a micro plate heat exchanger. Background Technology
[0002] With the increasing demand for efficient energy utilization in the industrial sector, plate heat exchangers have been widely used in industries such as chemical engineering, refrigeration, food processing, and HVAC due to their advantages of high efficiency, compact design, high heat transfer coefficient, and small footprint. As a highly efficient heat exchange device, plate heat exchangers are assembled from a series of corrugated metal plates stacked together, forming thin rectangular channels between the plates. Heat exchange occurs through these plates, greatly improving heat transfer efficiency and making them an important piece of equipment for energy conservation and emission reduction in modern industry.
[0003] Plate heat exchangers are composed of numerous corrugated metal plates stacked together, forming narrow channels between them. They are compact in structure and occupy little space. During operation, two fluids at different temperatures flow within the channels between adjacent plates, exchanging heat through the plates. The heat from the hot fluid is transferred to the plates, and then from the plates to the cold fluid, achieving heat exchange. Due to the large surface area of the plates and the corrugated structure which enhances fluid turbulence, the heat exchange efficiency is high.
[0004] In existing technologies, the position of the clamps in some heat exchangers is difficult to adjust flexibly during assembly, making it impossible for the heat exchange plates to fit tightly together. This leads to leakage when the medium flows between the plates, reducing heat exchange efficiency and affecting the stability and reliability of the entire heat exchanger. To address this issue, a micro plate heat exchanger is proposed. Utility Model Content

[0034] Reference Figures 1 to 3 The present invention provides an embodiment of a miniature plate heat exchanger, comprising a support plate 1, which is the basic support component of the entire miniature plate heat exchanger. A vertical plate 2 is fixedly connected to the top of the support plate 1, which serves as a support and positioning element and provides an installation base for a connecting plate 3. A connecting plate 3 is fixedly connected inside the vertical plate 2, which is a guide component for the sliding of a clamping plate 4, ensuring the smoothness and straightness of the clamping plate 4 during the sliding process.

A clamping mechanism is rotatably connected inside the connecting plate 3. A buffer mechanism is provided at the bottom of the support plate 1.
[0035] The clamping mechanism includes a rotating rod 5, which provides a base for the L-shaped rotating plate 6 to rotate. The outside of the rotating rod 5 is rotatably connected to the inside of the connecting plate 3. The outside of the rotating rod 5 is fixedly connected to the L-shaped rotating plate 6. The L-shaped rotating plate 6 can rotate by the rotating rod 5, thereby driving the slider 8 to move. The outside of the clamping plate 4 is fixedly connected to an L-shaped plate 7, which provides a sliding track for the slider 8 to ensure the smoothness of the slider 8 when sliding, thereby ensuring the stability of the movement of the clamping plate 4. The inside of the L-shaped plate 7 is slidably connected to the slider 8. The L-shaped rotating plate 6 can move the clamping plate 4 through the slider 8. The outside of the slider 8 is slidably connected to the outer surface of the clamping plate 4. One bottom end of the L-shaped rotating plate 6 is rotatably connected to the inside of the slider 8. The outside of the rotating rod 5 is fixedly connected to a locking component.
[0036] The locking assembly includes a disc 9, which has multiple holes inside. The inside of the disc 9 is fixedly connected to the outside of the rotating rod 5. A pin 10 is slidably connected inside the disc 9.

One end of the pin 10 is slidably connected to the inside of the connecting plate 3.
[0037] Reference Figure 4 and Figure 5 The buffer mechanism includes a guide rod 11, which guides the support plate 1 and the base 12. The guide rod 11 is slidably connected to the inside of the support plate 1. The bottom of the guide rod 11 is fixedly connected to the base 12, which is the basic support component of the buffer mechanism. A circular slide rod 13 is slidably connected inside the support plate 1. The circular slide rod 13 serves to assist in guiding and transmitting buffering force. The bottom of the circular slide rod 13 is slidably connected to the inside of the base 12. U-shaped blocks 14 and 15 are slidably connected to the outside of the circular slide rod 13. The function of U-shaped block 15 is to connect with U-shaped block 14. The buffer function is achieved through the buffer spring 16 and the connecting rod assembly. The buffer spring 16 is sleeved on the outside of the circular slide rod 13. The U-shaped block 14 and the U-shaped block 2 15 compress the buffer spring 16, so that the buffer spring 16 can absorb energy and achieve the buffering effect. The top of the buffer spring 16 is fixedly connected to the bottom of the U-shaped block 14, and the bottom of the buffer spring 16 is fixedly connected to the top of the U-shaped block 2 15. The connecting rod assembly is rotatably connected inside the U-shaped block 14. The top of the U-shaped block 14 is slidably connected to the bottom of the support plate 1, and the bottom of the U-shaped block 2 15 is slidably connected to the top of the base 12.

The internal part of the first linkage 17 is rotatably connected to the internal part of the second linkage 18 through a rotating shaft.
[0039] Reference Figure 3 and Figure 4A fixing plate 19 is fixedly connected to the top of the support plate 1. The fixing plate 19 is used to fix the fixing rod 20, providing a base for placing and positioning the heat exchange plate 23. The fixing rod 20 is fixedly connected inside the fixing plate 19. The fixing rod 20 plays the role of supporting and positioning the heat exchange plate 23. The other end of the fixing rod 20 is fixedly connected to the inside of the vertical plate 2. A threaded rod 21 is slidably connected inside the vertical plate 2. Rotating the threaded rod 21 can realize the clamping and loosening operation of the clamping plate 4, realizing further fixation of the heat exchange plate 23. The outside of the threaded rod 21 is slidably connected to the inside of the clamping plate 4. A nut 22 is threadedly connected to the outside of the threaded rod 21. The position of the clamping plate 4 is controlled by tightening and loosening the nut 22. The outside of the nut 22 is slidably connected to the outer surface of the clamping plate 4. The heat exchange plate 23 is placed on the top of the fixing rod 20. The heat exchange plate 23 is the key component for heat exchange in the micro plate heat exchanger. The top of the heat exchange plate 23 is slidably connected to the bottom of the connecting plate 3.
[0040] Working principle: The heat exchange plate 23 is placed on the top of the fixed rod 20, and the top of the heat exchange plate 23 slides in contact with the bottom of the connecting plate 3. The L-shaped rotating plate 6 is pulled and rotated by the rotating rod 5. The L-shaped rotating plate 6 is connected to the slider 8 by the rotation of the bottom, so that the slider 8 slides inside the L-shaped plate 7 and on the outer surface of the clamping plate 4. The slider 8 then pushes the clamping plate 4 to slide outside the connecting plate 3, so that the clamping plate 4 clamps and fixes the heat exchange plate 23. After the clamping plate 4 clamps the heat exchange plate 23, the pin 10 is inserted into the round hole on the disc 9 and inserted into the connecting plate 3 to lock the position of the L-shaped rotating plate 6, thereby fixing the clamped state of the heat exchange plate 23. At the same time, the threaded rod 21 is rotated and the position of the clamping plate 4 is further adjusted by the thread engagement with the nut 22, so as to further fix the heat exchange plate 23.
[0041] When the equipment is subjected to vibration, the bearing plate 1 presses down on the U-shaped block 14 to slide on the circular slide rod 13, compressing the buffer spring 16. The buffer spring 16 absorbs energy for buffering. The connecting rod 17 and the connecting rod 2 18 rotate relative to each other through the rotating shaft. At the same time, the U-shaped block 14 and the U-shaped block 2 15 slide on the circular slide rod 13 to achieve smooth buffering. The guide rod 11 and the circular slide rod 13 play a guiding role between the bearing plate 1 and the base 12, respectively.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
