Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange, in particular to a plate heat exchanger. Background Art

[0002] A plate heat exchanger is a highly efficient heat transfer device, typically consisting of a series of parallel metal plates. These plates are typically made of stamped, concave-convex stainless steel sheets. The concave-convex patterns between two adjacent plates are arranged 180 degrees relative to each other, forming staggered contact points. These contact points are joined by vacuum welding to form a high-pressure resistant staggered flow structure. The plates are typically also equipped with sealing gaskets to seal the fluid channels and guide the fluids to flow alternately into their respective flow channels. The plates also have four corner holes for the two heat transfer liquids to pass through. The metal plates are mounted in a frame with a fixed plate and a movable pressure plate on the side and clamped with clamping bolts. The metal plates and the movable pressure plate are typically suspended on an upper guide rod and positioned by a lower guide rod, the rod ends of which are fixed to support columns.

[0003] During the actual use of the plate heat exchanger, a certain pressure loss will be generated when the fluid continuously enters the channels between the heat exchange plates. This pressure loss will cause the kinetic energy of the fluid to decrease during the flow process, thereby reducing the flow rate. When the flow rate of the fluid changes, the flow state, pressure and temperature distribution of the fluid will change accordingly, thereby affecting the distribution of the fluid between the plates. The fluid distribution between different plates may become uneven. Plates with excessive flow may reduce the heat exchange efficiency due to excessive pressure drop, while plates with too small flow may waste energy due to insufficient heat exchange, which not only increases the energy consumption of the heat exchanger, but may even cause problems such as plate deformation and sealing failure, thereby affecting the normal operation of the equipment. For this reason, we propose a plate heat exchanger. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention utilizes a funnel-shaped design at the inlet of the boosting pipe to increase the pressure of the fluid after entering the boosting pipe. At the same time, the fluid will form a vortex in the boosting pipe after passing through the guide plate, which further increases the fluid pressure in the boosting pipe. Since the boosting groove is arranged in an hourglass shape, the fluid will be squeezed by the inner wall of the boosting groove when entering the boosting groove, and the pressure in the boosting pipe will accelerate the outflow of the fluid and make the fluid evenly discharged from each boosting groove, so that the pressure and flow rate of each section of the fluid in the guide pipe are relatively balanced. The fluid then enters the corresponding liquid storage layer through the guide groove, so that the fluid in each liquid storage layer is relatively evenly distributed, effectively reducing the situation of uneven fluid distribution.

[0018] 2. The present invention uses the socket to limit the insertion rod so that the rotating rod is fixed. After the sleeve is tightened, it will be at the same rotation angle. After the sleeves on both sides of the splint are at the same rotation angle, there will be no angle difference between the upper and lower sides of the splint. The two sides of the splint will maintain consistent clamping force up and down, and the heat exchange plate will remain clamped. Through the transmission of the transmission ring and the transmission belt, the slide cylinder in each limiter will also maintain the same angle. When the sleeves on one side of the splint should also be rotated to the same angle, the insertion rods on the sleeves can be inserted into the socket. According to the situation of the insertion rod in the socket, it can be detected whether the sleeve is rotated into place and whether the splint fully clamps the heat exchange plate, and the sleeve can be reinforced, thereby improving the sealing of the device during the heat exchange process.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-11The present invention provides a technical solution: a plate heat exchanger, including an end plate 1, which is provided with two water inlets 9 and two water outlets 10. Two connecting rods 5 are fixedly installed on one side of the end plate 1, and a column 4 is fixedly installed on one end of the two connecting rods 5. A slide rail 2 is fixedly connected between the end plate 1 and the column 4. A splint 6 is slidably installed on the two connecting rods 5, and two rollers 7 that cooperate with the slide rail 2 are rotatably installed on the upper end of the splint 6. Guide bars 3 are fixedly installed on both sides of the slide rail 2, and each roller 7 is provided with an annular groove 8 that cooperates with the guide bar 3. The splint 6 is limited by the connecting rod 5 to the splint 6, so that the distance between the splint 6 and the end plate 1 is adjusted. At the same time, the cooperation between the roller 7 and the slide rail 2, and the cooperation between the annular groove 8 and the guide bar 3, improves the stability of the splint 6 when sliding, and reduces the friction of the splint 6 when sliding.

[0033] A number of heat exchange plates 25 are provided between the end plate 1 and the splint 6. Each heat exchange plate 25 is provided with a limit groove 26 that cooperates with the connecting rod 5 at both ends. Four liquid holes 27 are provided at the four corners of each heat exchange plate 25. The liquid holes 27 correspond to the water inlet 9 and the water outlet 10 one by one. A sealing strip 30 for guiding the liquid is fixedly installed on one side of each heat exchange plate 25, and a sealing groove 31 that cooperates with the sealing strip 30 is provided on the other side. A liquid storage layer 32 is formed between two adjacent heat exchange plates 25 through the sealing strip 30 and the sealing groove 31. Each liquid storage layer 32 is liquid-in and liquid-out through the two liquid holes 27 on one side of the heat exchange plate 25, and the liquid holes 27 for liquid in and out on the two adjacent heat exchange plates 25 are arranged alternately, that is, the first heat exchange plate 25 has a plurality of liquid holes 27 on the upper and lower ends of the heat exchange plate 25. The plate 25 uses the two liquid holes 27 on the right side for liquid inlet and outlet, the second heat exchange plate 25 uses the two liquid holes 27 on the left side for liquid inlet and outlet, and so on and so forth. A number of diverter plates 29 are fixedly installed on one side of each heat exchange plate 25 for dispersing the liquid flowing into the liquid storage layer 32, and the flow directions of the fluids in the two adjacent liquid storage layers 32 are set in opposite directions. A number of diverter grooves 28 are set on each heat exchange plate 25, and each diverter groove 28 is set in a "human" shape. A frame 33 is fixedly installed on the edge of each heat exchange plate 25, and a limit strip 34 is fixedly installed on one side of each frame 33, and a card slot 40 for limiting the limit strip 34 is set on the other side. The hot fluid enters from the upper right water inlet 9 and passes through the first heat exchange plate 2 After passing through the liquid hole 27 at the upper right corner, a portion of the fluid enters the liquid storage layer 32 between the first heat exchange plate 25 and the second heat exchange plate 25, while the other portion of the fluid continues to flow backward and, through the cooperation of the sealing strip 30 and the sealing groove 31, cannot enter the liquid storage layer 32 formed by the second heat exchange plate 25 and the third heat exchange plate 25. The fluid will then continue to move and enter the liquid storage layer 32 formed by the third heat exchange plate 25 and the fourth heat exchange plate 25. The hot fluid entering the liquid storage layer 32 will be diverted by the diverter plate 29 and will flow evenly into the interior of the liquid storage layer 32. As the hot fluid continues to enter, the excess hot fluid will pass through the liquid hole 27 at the lower right corner of the heat exchange plate 25 after being restricted by the sealing strip 30, and will eventually be collected and discharged from the outlet 1 at the lower right corner of the end plate 1. 0 flows out, while the cold fluid flows in from the water inlet 9 at the lower left of the end plate 1, and will not be able to enter the liquid storage layer 32 between the first heat exchange plate 25 and the second heat exchange plate 25 after passing through the limit of the sealing strip 30. After continuing to flow, it will enter the liquid storage layer 32 composed of the second heat exchange plate 25 and the third heat exchange plate 25. Similarly, the cold fluid will also flow evenly to the inside of the liquid storage layer 32 after being diverted by the diverter plate 29, and finally flow out from the water outlet 10 at the upper left of the end plate 1 after being gathered. The cold fluid and the hot fluid flow alternately in the adjacent liquid storage layers 32 for heat exchange. At the same time, the diverter groove 28 on the heat exchange plate 25 increases the contact area between the fluid and the heat exchange plate 25, thereby improving the heat exchange efficiency. The hot fluid flows from top to bottom, while the cold fluid flows from bottom to top.It also improves the heat exchange efficiency of hot and cold fluids.

[0034] Each water inlet 9 is fixedly installed with a guide pipe 35, each guide pipe 35 passes through the corresponding liquid hole 27, and is provided with a plurality of guide grooves 36, the guide grooves 36 correspond to the liquid storage layer 32 corresponding to the water inlet 9, and are interconnected. A boosting pipe 37 is fixedly installed in each guide pipe 35, and the inlet of each boosting pipe 37 is funnel-shaped, and each boosting pipe 37 is provided with a plurality of boosting grooves 38, each boosting groove 38 The boosting grooves 38 are arranged in a spiral on the boosting pipe 37. A number of guide plates 39 are fixedly installed on the inner wall of the inlet of each boosting pipe 37. Each guide plate 39 is arranged in an inclined manner and arranged in a spiral on the inner wall of the boosting pipe 37. After the cold and hot fluids enter the corresponding water inlet 9, they will first enter the boosting pipe 37. Since the inlet of the boosting pipe 37 is arranged in a funnel shape, the pressure of the fluid will increase after entering the boosting pipe 37. At the same time, due to the boosting A guide plate 39 is fixedly installed at the inlet of the pressure pipe 37, and the guide plates 39 are all arranged at an angle. After passing through the guide plate 39, the fluid will form a vortex in the boosting pipe 37, which will further increase the fluid pressure in the boosting pipe 37. As the fluid continues to enter the boosting pipe 37, the fluid in the boosting pipe 37 will flow out through the boosting groove 38 thereon. Since the boosting groove 38 is arranged in an hourglass shape, the fluid will be squeezed by the inner wall of the boosting groove 38 when entering the boosting groove 38. The pressure in the boosting pipe 37 will accelerate the outflow speed of the fluid and make the fluid evenly discharged from each boosting groove 38. After discharging the boosting groove 38, the fluid will diffuse along the inner wall of the boosting groove 38 into the guide pipe 35, so that the pressure and flow rate of each section of the fluid in the guide pipe 35 are relatively balanced. The fluid then enters the corresponding liquid storage layer 32 through the guide groove 36, so that the fluid in each liquid storage layer 32 is relatively evenly distributed, effectively reducing the problem of uneven fluid distribution.

[0035] A plurality of limiting holes 11 are provided on both sides of the end plate 1 and the splint 6, and a rotating rod 13 is rotatably installed between each two corresponding limiting holes 11 in the front and rear. A limiting ring 14 that cooperates with the end plate 1 is fixedly installed on one end of each rotating rod 13, and a positioning rod 15 is fixedly installed on each limiting ring 14. A plurality of positioning holes 12 for limiting the positioning rod 15 are provided on the end plate 1, and the positioning holes 12 correspond to the positioning rods 15 one by one. A threaded groove 16 is also provided on each rotating rod 13, and a sleeve 17 is rotatably installed on each rotating rod 13. A threaded strip 18 that cooperates with the threaded groove 16 is fixedly installed on the inner wall of each sleeve 17. A limiting member 24 is provided on the left and right sides of the splint 6, and each limiting member 24 is rotatably installed There are several slides 20, each of which is fixedly mounted with a transmission ring 22 on the outer wall of each slide 20, and a transmission belt 23 for connecting the transmission rings 22 is provided in each limiter 24. The slides 20 correspond to the sleeves 17 one by one, and each slide 20 is provided with a socket 21. Each sleeve 17 is fixedly mounted with a plug rod 19 that matches the socket 21. After the heat exchanger 25 is installed in place, the limit strip 34 on the frame 33 is inserted into the corresponding card slot 40, so that the adjacent heat exchanger fins 25 can be accurately aligned, and the displacement of the heat exchanger fins 25 during use can be reduced to prevent leakage during use of the device, and then the splint 6 is pushed toward the end plate 1 and the heat exchanger fin 25 is clamped, and the rotating rod 13 is passed through in sequence. Through the end plate 1 and the limiting holes 11 on the splint 6, the limiting ring 14 at the end of the rotating rod 13 is pressed against one side of the end plate 1, and the positioning rod 15 on the limiting ring 14 is inserted into the corresponding positioning hole 12, so that the rotating rod 13 is fixed and cannot rotate, and then the sleeve 17 is rotated and installed on the rotating rod 13 in sequence, and the sleeve 17 is sleeved on the rotating rod 13 through the cooperation of the threaded strip 18 and the threaded groove 16, and one end of the sleeve 17 is pressed against the splint 6. After tightening the sleeve 17, the splint 6 is fixed and the heat exchange fin 25 is kept clamped. Then the slides 20 on the limiting member 24 are sleeved on the sleeve 17 one by one, and the insertion rod 19 on the sleeve 17 is inserted into the corresponding insertion hole 21 on the slide 20. Since the rotating rod 13 is fixed, the sleeve 17 is tightened. When the sleeves 17 on both sides of the splint 6 are at the same rotation angle, there will be no angle difference between the upper and lower sides of the splint 6. The clamping force on both sides of the splint 6 will be consistent, and the heat exchange plate 25 will remain clamped. Through the transmission of the transmission ring 22 and the transmission belt 23, the slide 20 in each limit member 24 will also maintain the same angle. When the sleeves 17 on one side of the splint 6 are also rotated to the same angle, the insertion rod 19 on the sleeve 17 can be inserted into the socket 21. According to the situation of the insertion rod 19 in the socket 21, it can be detected whether the sleeve 17 is rotated into place and whether the splint 6 fully clamps the heat exchange plate 25, and the sleeve 17 can be reinforced, thereby improving the sealing of the device during the heat exchange process.

[0036] Specifically, first select a suitable number of heat exchange plates 25, and limit the limit grooves 26 through the connecting rod 5, install the heat exchange plates 25 in place, and insert the limit strips 34 on the frame 33 into the corresponding card slots 40, so that adjacent heat exchange plates 25 can be accurately aligned, and the displacement of the heat exchange plates 25 during use can be reduced to prevent leakage during use of the device, and then push the clamping plate 6 toward the end plate 1 and clamp the heat exchange plates 25, and pass the rotating rod 13 through the limiting holes 11 on the end plate 1 and the clamping plate 6 in turn, so that the limiting ring 14 at the end of the rotating rod 13 is against one side of the end plate 1, and the positioning rod 15 on the limiting ring 14 is inserted into the corresponding positioning hole 12, so that the rotating rod 13 is fixed and cannot rotate, and then the sleeve 17 is rotated and installed on the rotating rod 13 one by one, and then The screw thread strip 18 cooperates with the screw thread groove 16, so that the sleeve 17 is sleeved on the rotating rod 13, and one end is against the splint 6. After the sleeve 17 is tightened, the splint 6 is fixed and the heat exchange plate 25 remains clamped. Then the slide cylinder 20 on the limiter 24 is sleeved on the sleeve 17 one by one, and the insertion rod 19 on the sleeve 17 is inserted into the socket 21 on the corresponding slide cylinder 20. Since the rotating rod 13 is fixed, the sleeve 17 will be at the same rotation angle after tightening. After the sleeves 17 on both sides of the splint 6 are at the same rotation angle, there will be no angle difference between the upper and lower sides of the splint 6. The two sides of the splint 6 will maintain the same clamping force up and down, and the heat exchange plate 25 will remain clamped. Through the transmission ring 22 and the transmission belt 23, the slide cylinder 20 in each limiter 24 will also be Keeping the same angle, when the sleeves 17 on one side of the splint 6 are also rotated to the same angle, the insertion rods 19 on the sleeves 17 can be inserted into the insertion holes 21. According to the situation of the insertion rods 19 in the insertion holes 21, it is possible to detect whether the sleeve 17 is rotated into place and whether the splint 6 fully clamps the heat exchange plate 25, and the sleeve 17 can be reinforced, thereby improving the sealing performance of the device during the heat exchange process. The hot fluid enters from the water inlet 9 on the upper right, passes through the liquid hole 27 on the upper right of the first heat exchange plate 25, and a part of the fluid enters the liquid storage layer 32 between the first heat exchange plate 25 and the second heat exchange plate 25, and the other part of the fluid continues to flow backward and cannot enter the second heat exchange plate 25 and the third heat exchange plate 25 formed by the cooperation of the sealing strip 30 and the sealing groove 31. The hot fluid will flow into the liquid storage layer 32 and then continue to move and enter the liquid storage layer 32 composed of the third heat exchange plate 25 and the fourth heat exchange plate 25. The hot fluid entering the liquid storage layer 32 will be diverted by the diverter plate 29 and will flow evenly to the inside of the liquid storage layer 32. As the hot fluid continues to enter, the excess hot fluid will be restricted by the sealing strip 30 and will flow out from the liquid hole 27 at the lower right of the heat exchange plate 25. It will eventually be collected and flow out from the water outlet 10 at the lower right of the end plate 1, while the cold fluid will flow in from the water inlet 9 at the lower left of the end plate 1 and will not be able to enter the liquid storage layer 32 between the first heat exchange plate 25 and the second heat exchange plate 25 after being limited by the sealing strip 30. It will continue to flow and enter the liquid storage layer 32 composed of the second heat exchange plate 25 and the third heat exchange plate 25.By analogy, the cold fluid will also flow evenly to the inside of the liquid storage layer 32 after being diverted by the diverter plate 29, and will finally flow out from the water outlet 10 on the upper left of the end plate 1 after being collected. The cold fluid and the hot fluid will flow alternately in the adjacent liquid storage layer 32 to exchange heat. At the same time, the diverter groove 28 on the heat exchange plate 25 increases the contact area between the fluid and the heat exchange plate 25, thereby improving the heat exchange efficiency. Moreover, the flow direction of the hot fluid is from top to bottom, while the flow direction of the cold fluid is from bottom to top, thereby improving the heat exchange efficiency of the cold and hot fluids. After the cold and hot fluids enter the corresponding water inlet 9, they will first enter the boosting pipe 37. Since the inlet of the boosting pipe 37 is arranged in a funnel shape, the pressure of the fluid will increase after entering the boosting pipe 37. At the same time, since a guide plate 39 is fixedly installed at the inlet of the boosting pipe 37, and the guide plate 39 is arranged at an angle, the fluid will increase after passing through the guide plate 39. After the plate 39 is formed, a vortex is formed in the boosting pipe 37, further increasing the fluid pressure in the boosting pipe 37. As the fluid continues to enter the boosting pipe 37, the fluid in the boosting pipe 37 will flow out through the boosting groove 38 thereon. Since the boosting groove 38 is configured in an hourglass shape, the fluid will be squeezed by the inner wall of the boosting groove 38 when entering the boosting groove 38. The pressure in the boosting pipe 37 will accelerate the outflow of the fluid and make the fluid evenly discharged from each boosting groove 38. After exiting the boosting groove 38, the fluid will diffuse along the inner wall of the boosting groove 38 into the guide pipe 35, making the pressure and flow rate of each section of the fluid in the guide pipe 35 relatively balanced. The fluid then enters the corresponding liquid storage layer 32 through the guide groove 36, making the fluid distribution in each liquid storage layer 32 relatively even, effectively reducing the problem of uneven fluid distribution.
