Abstract
Description
Technical Field
[0001] The invention relates to the field of plate heat exchange, and in particular to a plate heat exchanger with plug-in type forced flow optimization distribution. Background Art
[0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets (i.e., heat exchange plates) with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. It is an ideal equipment for liquid-liquid and liquid-steam heat exchange. The types of plate heat exchangers are mainly frame type (detachable type) and brazed type. Among them, the detachable plate heat exchanger is composed of many stamped corrugated thin plates at a certain interval, sealed by gaskets on all sides, and overlapped and compressed with frames and compression spirals. The four corner holes of the plates and gaskets form the distribution pipes and collection pipes of the fluid, and at the same time, the cold and hot fluids are reasonably separated, so that they flow in the flow channels on both sides of each plate respectively, and heat exchange is carried out through the plates.
[0003] Most existing plate heat exchangers directly introduce the refrigerant and the coolant into the device, and then enter adjacent and isolated areas for heat exchange, and then discharge them after the heat exchange is completed. In this design, the flow directions of the refrigerant and the coolant are usually opposite, that is, one flows from bottom to top and the other flows from top to bottom. This countercurrent arrangement is designed to maximize the heat exchange efficiency. However, in actual operation, there is a problem of inconsistent flow rate. Specifically, the flow rate of the refrigerant and the coolant is relatively fast when they first enter the heat exchange area, but when they are about to flow out, that is, when they are close to the outlet, the flow rate will gradually slow down due to the consumption of kinetic energy. This inconsistency in flow rate will lead to uneven heat exchange process. Specifically, the faster-flowing fluid may not be fully discharged before heat exchange with the slower-flowing fluid, resulting in uneven heat exchange in the entire plate heat exchanger, thereby reducing the heat exchange effect and poor practicality. Summary of the invention

The two sets of movable blocks 441 are arranged at an oblique angle toward one side of the two sets of fixed sleeves 44, and there is a gap between the two sets of corrugated plates 10 and the two sets of fixed sleeves 44.
[0049] In the present invention, when heat exchange is required, the refrigerant (liquid fluorine) and the cooling liquid (50% ethylene glycol solution) are respectively introduced into the entire device through the first connecting pipe 2 and the third connecting pipe 22. Since the first connecting pipe 2 and the second connecting pipe 21 correspond to the positions of the two sets of isolation rings on the sealing gasket 3 in the cooling zone 6, and the third connecting pipe 22 and the fourth connecting pipe 23 correspond to the positions of the two sets of isolation rings on the sealing gasket 3 in the refrigeration zone 7, under the action of the isolation rings in the cooling zone 6 and the refrigeration zone 7, the refrigerant and the cooling liquid can only enter the corresponding refrigeration zone 7 and the cooling zone 6 (that is, ensure that the refrigerant and the cooling liquid will not mix). With the continuous injection of the refrigerant and the cooling liquid, the refrigerant in the refrigeration zone 7 flows from bottom to top and is finally discharged from the second connecting pipe 21. At the same time, the cooling liquid in the cooling zone 6 flows from top to bottom and is finally discharged from the fourth connecting pipe 23. During this period, the heat of the liquids in the refrigeration zone 7 and the cooling zone 6 can be exchanged with each other through the heat conduction of the corrugated plate 10, thereby achieving the purpose of heat exchange.
[0050] Conventional heat exchangers only pass refrigerant and cooling liquid directly into the device. When the refrigerant enters the first connecting pipe 2 and enters the three groups of refrigeration zones 7 in turn, although the isolation ring on the sealing gasket 3 (the sealing gasket 3 in the cooling zone 6) can effectively isolate the cooling zone 6 to prevent the refrigerant from directly penetrating, when the refrigerant flows near the cooling zone 6, the cooling liquid will be injected into the cooling zone 6, thereby indirectly absorbing heat from the cooling liquid. At the same time, since the conventional refrigerant is liquid fluorine, and liquid fluorine will undergo a phase change (i.e., from liquid to gas) after absorbing heat, the amount of refrigerant in the cooling zone 7 that enters the refrigerant later will gradually decrease, resulting in differences in the amount of refrigerant in the three groups of refrigeration zones 7. Therefore, when the same refrigerant is injected, the difference in the amount of refrigerant will cause unevenness in the heat exchange process. Therefore, this device The following improvements have been made: a distribution pipe 25 is connected to the first connecting pipe 2, and three groups of spray valves 26 are installed at the bottom of the distribution pipe 25 through a connecting block 27 and a connecting pipe. The bottoms of the three groups of spray valves 26 are all provided with streamlined nozzles 261, and the positions of the three groups of spray valves 26 correspond to the positions of the three groups of refrigeration zones 7 respectively. When the refrigerant is passed into the first connecting pipe 2, it will first enter the distribution pipe 25 connected to the first connecting pipe 2, and under the action of the three groups of spray valves 26 at the bottom of the distribution pipe 25, it will be sprayed into the three groups of refrigeration zones 7 through the streamlined nozzles 261. Since the spray valve 26 can adjust the flow rate of the liquid, it can ensure that the pressure and flow rate of the refrigerant sprayed from each place are the same, thereby effectively ensuring that the flow rate of the refrigerant entering the three groups of refrigeration zones 7 is the same, thereby ensuring that the heat exchange conditions in each area are relatively consistent, and effectively improving the heat exchange effect.
[0051] Subsequently, the refrigerant liquid sprayed into the refrigeration zone 7 will impact the inner bottom wall of the lower guide frame 4, and under the continuous spraying of the refrigerant liquid and the shape of the lower guide frame 4, it will be sprayed on the multiple groups of first blades 43, thereby driving the multiple groups of first blades 43 located on both sides of the diverter groove 41 to rotate counterclockwise (the rotation direction is Figure 6 As shown in the figure, since the multiple groups of first blades 43 are all arranged at an angle, when the refrigerant drives them to rotate, the refrigerant itself will also be subjected to the reaction force from the first blades 43. This reaction force helps to reduce the speed at which the refrigerant is sprayed out from the liquid outlet 411 of the lower guide frame 4. At the same time, the refrigerant will collide with each other under the guidance of the multiple groups of first blades 43. This collision can prompt the refrigerant to be sprayed out from the diverter groove 41 in a more dispersed manner. The deceleration can extend the residence time of the refrigerant in the refrigeration zone 7, which means that the refrigerant has more opportunities to exchange heat with the coolant in the coolant zone 6, thereby effectively improving the heat exchange efficiency. At the same time, the mutual collision and subsequent spraying of the refrigerant at the diverter groove 41 can cause certain interference to its overall flow, thereby enhancing its turbulence intensity. Since the turbulent flow of the refrigerant has higher heat transfer efficiency and better heat absorption effect than laminar flow, the heat exchange efficiency can be further improved.
[0052] The rotation of the plurality of first blades 43 can drive the connecting shaft 421 and the first rotating shaft 42 to rotate, thereby driving the plurality of fourth blades 52 in the cooling zone 6 to rotate counterclockwise (the rotation direction is Fig.14 As shown in the figure, since the refrigerant liquid enters the second pipe 21 from the first pipe 2 and exits (i.e. from bottom to top), and the cooling liquid enters the fourth pipe 23 from the third pipe 22 and exits (i.e. from top to bottom), the plurality of fourth blades 52 are located close to the cooling liquid outflow position (i.e. the through groove corresponding to the position of the fourth pipe 23). When the cooling liquid passes into the cooling zone 6 through the third pipe 22, it will flow to the fourth blade 52 under the continuous introduction of the cooling liquid and the sequential guidance of the upper guide plate 31, the middle guide plate 32 and the lower guide plate 33 (the middle guide plate 32 can increase the residence time of the cooling liquid in the cooling zone 6 while guiding the cooling liquid so as to better exchange heat), and when the cooling liquid flows to the fourth blade 52, its flow rate It will gradually slow down due to the consumption of kinetic energy, and the turbulence intensity will be weakened. The rotation of the fourth fan blade 52 can give the coolant a kinetic energy, which is helpful to improve and maintain the turbulent state of the coolant in the coolant zone 6, thereby effectively improving the heat exchange efficiency. In addition, since the multiple groups of fourth fan blades 52 are all V-shaped structures, and the tips of the multiple groups of fourth fan blades 52 are facing the lower guide plate 33, the multiple groups of fourth fan blades 52 will rotate to push the coolant fluid guided by the lower guide plate 33 to the two groups of plate bodies constituting the coolant zone 6 (the two groups of plate bodies constituting the two outermost groups of coolant zones 6 are the side plate 1 and the corrugated plate 10, and the two groups of plate bodies constituting the two groups of coolant zones 6 in the middle are two groups of corrugated plates 10), thereby effectively improving the heat exchange efficiency and heat exchange effect.
[0053] After the refrigerant in the refrigeration zone 7 is sprayed out through the diverter groove 41 and the liquid outlet 411, it will move upward and pass through the gap between the two sets of fixed sleeves 44 and the two sets of movable blocks 441 (such as Figure 8 As shown in the figure, when the refrigerant passes through the gap between the two groups of fixed sleeves 44 and the two groups of movable blocks 441, the refrigerant will apply a pressure to the two groups of movable blocks 441 when the movable blocks 441 are set at an angle toward the fixed sleeve 44, so that the two groups of movable blocks 441 move away from each other until the two groups of movable blocks 441 contact the two groups of corrugated plates 10 in the refrigeration zone 7. At this time, the spring 443 is compressed, and its elastic force generates a pulling force on the two groups of fixed sleeves 44, thereby indirectly applying a force in the opposite direction to the corrugated plates 10, thereby ensuring that the two groups of corrugated plates 10 in the refrigeration zone 7 can effectively prevent the leakage of the refrigerant even if they face a large internal impact (i.e., the impact of the refrigerant), thereby effectively ensuring the smooth progress of the heat exchange process.
[0054] After passing through the gap between the diverter groove 41 and the movable block 441, the refrigerant will come to the liquid inlet 452. At this time, its flow rate will gradually slow down due to the consumption of kinetic energy, and the turbulence will weaken. Therefore, its flow rate is not as good as that of the coolant at the same height. Therefore, it is necessary to convert part of the kinetic energy of the coolant to the refrigerant to improve the turbulence effect of the refrigerant at this location. Since the six groups of corrugated plates 10 are all installed with an adapter box 13, and the adapter box 13 is provided with a small gear 131 and a large gear 132 and meshes with each other, and the second rotating shaft 46 is fixedly connected to the small gear 131, and the third rotating shaft 5 is fixedly connected to the large gear 132, therefore, when the coolant in the cooling zone 6 flows to the multiple groups of third blades 51 under the guidance of the upper guide plate 31, it will push the multiple groups of third blades 51 and make the multiple groups of third blades 51 and the third rotating shaft 5 start to rotate clockwise (the direction of rotation is Fig.13 As shown in the figure, the large gear 132, the small gear 131, the second rotating shaft 46 and the plurality of second blades 461 on the second rotating shaft 46 can be driven to rotate in sequence. Since the large gear 132 and the small gear 131 are meshed with each other, the plurality of second blades 461 in the refrigeration zone 7 rotate counterclockwise (the rotation direction is Fig.10 As shown in the figure, the rotation of the plurality of second blades 461 can draw the refrigerant into the upper guide frame 45, and move it upward to the inner top wall of the upper guide frame 45 through the baffle plate 451, and finally be discharged through the through groove on the corrugated plate 10 and the second connecting pipe 21.
[0055] Since the multiple sets of third fans are all arranged in a straight manner, they can better absorb the kinetic energy of the cooling liquid to increase its rotation speed, that is, effectively increase the rotation speed of the second fan blade 461, and since the diameter of the small gear 131 is smaller than that of the large gear 132, the angular velocity of the small gear 131 will be faster when the linear velocity is the same through meshing (that is, the rotation speed of the third fan blade 51 is smaller than that of the second fan blade 461), thereby further increasing the rotation speed of the second fan blade 461, and then effectively improving the turbulent effect of the refrigerant at the second fan blade 461 in the refrigeration zone 7, that is, effectively improving the heat exchange efficiency. Since liquid fluorine (refrigerant) will change from liquid to gas after absorbing heat, and the heat absorption capacity of gaseous fluorine is weaker than that of liquid fluorine, it is necessary to discharge the gaseous fluorine from the refrigeration zone 7 as soon as possible to avoid reducing the heat exchange efficiency. When the gas-liquid mixture of fluorine (that is, the mixture of liquid fluorine and gaseous fluorine) passes through the second fan blade 461, due to the multiple sets of second fan blades 46 1 rotates, the gas-liquid mixture is accelerated and moves along the rotation direction of the second rotating shaft 46. At this time, since the density of the liquid is greater than that of the gas, and the second fan blade 461 adopts a V-shaped structure and is arranged in a curved shape, the liquid fluorine will be mostly concentrated in the depression on the second fan blade 461 under the action of its own density and inertia, while the gaseous fluorine is squeezed to the two sides of the second fan blade 461 and moves upward due to its smaller density. Due to the existence of the baffle plate 451, the gaseous fluorine is diverted when flowing through the baffle plate 451, and moves upward from the two sides of the baffle plate 451, and is finally discharged through the through groove and the second connecting pipe 21, while the liquid fluorine is more retained near the second fan blade 461, and only a small part moves upward with the gaseous fluorine and is discharged through the through groove and the second connecting pipe 21. This design not only improves the heat exchange time between the liquid fluorine (refrigerating liquid) and the cooling liquid in the cooling zone 6, but also accelerates the discharge of the gaseous fluorine, thereby further improving the heat exchange efficiency.
