Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, specifically to a herringbone corrugated plate heat exchanger structure for enhanced heat transfer. Background Technology

[0002] Plate heat exchangers are composed of stamped, textured stainless steel plates. The textures between two adjacent plates are arranged at 180-degree angles, creating staggered contact points. These contact points are then joined together by vacuum welding, forming the high-pressure resistant, staggered flow structure of the plate heat exchanger. This staggered flow structure causes strong turbulence in the hot and cold fluids within the plate heat exchanger, resulting in high heat exchange efficiency.

[0003] Chinese patent CN202022267135.8 discloses a cleaning structure for maintaining a plate heat exchanger. The plate heat exchanger includes an inlet pipe, an outlet pipe, an inlet pipe, and an outlet pipe. The inlet pipe and outlet pipe are connected, as are the inlet pipe and outlet pipe. The inlet pipe and outlet pipe are connected to a connecting pipe via flanges. A liquid exchange valve is fixedly connected to the other end of the connecting pipe. A cleaning device and a hot water pipe are fixedly connected to the other end of the liquid exchange valve. The cleaning device includes an acid / alkali solution storage tank, a stirrer, a booster pump, an inlet pipe, and an outlet pipe. The inlet of the booster pump is connected to the inlet pipe, which is located inside the acid / alkali solution storage tank. The outlet is fixedly connected to the outlet pipe, which is also fixedly connected to the liquid exchange valve. This device is convenient for cleaning, saves time and effort, and is easy to operate.

[0004] However, the following drawbacks still exist:

[0005] It is difficult to disassemble and clean the heat exchange fins inside, resulting in a lack of thorough cleaning and leaving a lot of dirt on the fins, which affects the heat exchange effect and reduces the heat transfer efficiency. Utility Model Content

[0028] Example

[0029] This embodiment provides a herringbone corrugated plate heat exchanger structure to enhance heat transfer, such as... Figures 1-4 As shown, it includes: a base plate 1, with a fixed frame 2 and a support frame 3 fixedly connected to the outer part of the top of the base plate 1, and multiple positioning guide rods 5 symmetrically arranged between the support frames 3. A movable pressure plate 4 is slidably connected to the positioning guide rods 5. A hydraulic rod 12 is fixedly connected to the center of the surface of the support frame 3. The telescopic end of the hydraulic rod 12 is fixedly connected to the movable pressure plate 4. Multiple herringbone corrugated heat exchange plates 8 are slidably connected to the positioning guide rods 5. Heat exchange chambers 9 are opened on the herringbone corrugated heat exchange plates 8; a toggle mechanism 10 drives the herringbone corrugated heat exchange plates 8 to move along the positioning guide rods 5, changing the spacing between two adjacent herringbone corrugated heat exchange plates 8; a strengthening mechanism 11 performs high-pressure flushing of the heat exchange chambers 9; and an inlet pipe 6 and an outlet pipe 7 are fixedly connected from top to bottom on the side of the fixed frame 2 away from the support frame 3, and the inlet pipe 6 and the outlet pipe 7 are connected to the heat exchange chambers 9.

[0030] A heat transfer enhancement structure for a herringbone corrugated plate heat exchanger employing the above technical solution includes a toggle mechanism 10 and a strengthening mechanism 11. A third electric push rod 1008 moves the connecting seat 1009, causing the toggle 1006 to move between two adjacent herringbone corrugated heat exchange plates 8. An actuating sliding block 1003 moves the mounting block 1005 and the toggle 1006 towards the herringbone corrugated heat exchange plates 8, inserting the toggle 1006 into the gap between the two adjacent herringbone corrugated heat exchange plates 8, thus enhancing the heat transfer between the two adjacent plates. When the herringbone corrugated heat exchange plates 8 are separated, the third electric push rod 1008 is activated, which drives the paddle 1006 to move away from the herringbone corrugated heat exchange plates 8. This causes the paddle 1006 to move the herringbone corrugated heat exchange plates 8, increasing the spacing between the herringbone corrugated heat exchange plates 8. The booster pump 1104 draws cleaning fluid into the sliding rod 1002, which is then sprayed out from the sliding block 1003 to flush the heat exchange chamber 9 inside the herringbone corrugated heat exchange plates 8, flushing out impurities, improving heat transfer efficiency, and facilitating heat exchange.

[0031] The actuating mechanism 10 includes a fixed block 1001 fixedly connected to the fixed frame 2 and the support frame 3. A sliding rod 1002 is fixedly connected between the two fixed blocks 1001. A sliding block 1003 is slidably connected to the surface of the sliding rod 1002. A first electric push rod 1004 is fixedly connected to the bottom of the sliding block 1003. A mounting block 1005 is fixedly connected to the bottom of the first electric push rod 1004. A paddle 1006 is fixedly installed at the bottom of the mounting block 1005. A connecting frame 1007 is fixedly connected between the upper and lower sliding blocks 1003. A third electric push rod 1008 is fixedly installed on one side of the support frame 3. A connecting seat 1009 is fixedly installed at the center of the surface of the connecting frame 1007. The telescopic end of the third electric push rod 1008 is fixedly connected to the connecting seat 1009.

[0032] In order to insert the tweezer 1006 into the gap between two adjacent herringbone corrugated heat exchange plates 8, the thickness of the tweezer 1006 gradually decreases from top to bottom and is arranged in a triangular shape. The sliding block 1003 is located in the center above the herringbone corrugated heat exchange plate 8.

[0033] To flush the heat exchange chamber 9, the strengthening mechanism 11 includes a second electric push rod 1101 fixedly connected to one side of the third electric push rod 1008. A high-pressure flushing pipe 1102 is fixedly connected to the telescopic end of the second electric push rod 1101. Flushing holes 1103 are provided on both sides of the high-pressure flushing pipe 1102. A booster pump 1104 is fixedly installed on the top of the base plate 1. An inlet pipe 1106 is fixedly connected to the inlet of the booster pump 1104, and the outlet of the booster pump 1104 is fixedly connected to the high-pressure flushing pipe 1102 via a water supply pipe 1105. After the two herringbone corrugated heat exchange plates 8 separate, the second electric push rod 1101 is activated, causing the high-pressure flushing pipe 1102 to reciprocate along the heat exchange chamber 9, flushing impurities within the heat exchange chamber 9.

[0034] In order to better compress the herringbone corrugated heat exchange plate 8 and make the herringbone corrugated heat exchange plate 8 evenly stressed, the length and width of the hydraulic rod 12 are larger than the length and width of the herringbone corrugated heat exchange plate 8, and the support frame 3 is set in an H shape.

[0035] To improve the cleaning effect, both the water inlet pipe 1106 and the water delivery pipe 1105 are set as explosion-proof pipes, and the flushing hole 1103 is set perpendicular to the base plate 1.

[0036] In order to collect the rinsing water, a water collection tank is provided on the top of the base plate 1 (not shown in the figure). The inlet pipe 6 and outlet pipe 7 are connected to the external pipeline. The external liquid that needs to be heated is introduced into the inlet pipe 6 and outlet pipe 7, and heat exchange is carried out under the action of the herringbone corrugated heat exchange plate 8.

[0037] In summary, the herringbone corrugated plate heat exchanger enhanced heat transfer structure provided in this embodiment has the following advantages: It is equipped with a toggle mechanism 10 and a strengthening mechanism 11. The connecting seat 1009 is moved by the third electric push rod 1008, thereby moving the toggle piece 1006 between two adjacent herringbone corrugated heat exchange plates 8. The sliding block 1003 then moves the mounting block 1005 and the toggle piece 1006 towards the herringbone corrugated heat exchange plate 8, allowing the toggle piece 1006 to insert into the gap between the two adjacent herringbone corrugated heat exchange plates 8. The two adjacent herringbone corrugated heat exchange plates 8 are separated. The third electric push rod 1008 is activated to drive the paddle 1006 to move away from the herringbone corrugated heat exchange plate 8. This causes the paddle 1006 to move the herringbone corrugated heat exchange plate 8, increasing the spacing between the herringbone corrugated heat exchange plates 8. The cleaning fluid is then pumped into the sliding rod 1002 by the booster pump 1104 and sprayed out from the sliding block 1003 to flush the heat exchange chamber 9 inside the herringbone corrugated heat exchange plate 8, flushing out impurities, improving the heat transfer effect, and facilitating heat exchange.

[0038] In use, the third electric push rod 1008 drives the connecting seat 1009 to move, thereby moving the paddle 1006 between two adjacent herringbone corrugated heat exchange plates 8. The sliding block 1003 then moves the mounting block 1005 and the paddle 1006 towards the herringbone corrugated heat exchange plates 8, causing the paddle 1006 to insert into the gap between the two adjacent herringbone corrugated heat exchange plates 8, separating them. The third electric push rod 1008 then moves the paddle 1006 away from the herringbone corrugated heat exchange plates. The hot plate 8 moves in a certain direction, causing the lever 1006 to move the herringbone corrugated heat exchange plate 8, increasing the spacing between the herringbone corrugated heat exchange plate 8. The booster pump 1104 draws cleaning fluid into the sliding rod 1002, which is then sprayed out from the sliding block 1003 to flush the heat exchange chamber 9 inside the herringbone corrugated heat exchange plate 8, flushing out impurities. The second electric push rod 1101 is then activated to drive the high-pressure flushing pipe 1102 to move back and forth along the herringbone corrugated heat exchange plate 8, improving the cleaning effect on impurities and thus improving the heat transfer effect.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
