Description

Technical Field

[0001] The present invention relates to the technical field of coolers, and in particular to a plate-type cooler. Background Art

[0002] Plate Heat Exchanger is a highly efficient heat exchange equipment widely used in chemical, food processing, pharmaceutical, HVAC, shipbuilding and other industries. This type of cooler uses metal plates as heat transfer elements to exchange heat through narrow channels between the plates. The working principle of plate heat exchanger is based on countercurrent heat exchange, that is, two fluids (a hot fluid and a cold fluid) flow in opposite directions to transfer heat through metal plates. The hot fluid flows through the small gaps between a series of parallel plates, while the cold fluid flows through another set of gaps between adjacent plates. In this way, heat is transferred from the hot fluid to the cold fluid to achieve the purpose of cooling or heating.

[0003] However, the existing plate coolers have very narrow channels between the plates, so after long-term use, they are prone to scaling and clogging. They need to be cleaned frequently to ensure a good heat exchange effect. Moreover, scaling will also accelerate the aging speed of the sealing ring between the plates, affecting the service life of the plate heat exchanger. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] Reference Figure 1 to Figure 6, is an embodiment of the present invention, and proposes a plate-type cooler, including a box body 1 and a spray pipe 2, and also includes a heat exchange plate 3, a plurality of heat exchange plates 3 are arranged in the box body 1 at intervals and are located below the spray pipe 2, and adjacent heat exchange plates 3 are connected, and the heat exchange plate 3 includes a plate body 301, and the plate body 301 is longitudinally arranged in the box body 1, and the plate body 301 has a cavity 302, and the cavity 302 is used to pass heat exchange water; the spoiler strip 10 has a plurality of, a plurality of The spoiler strip 10 is arranged at intervals in the cavity 302, and the spoiler strip 10 has a deflection portion 1001 and a spoiler portion 1002. One end of the deflection portion 1001 is arranged on the inner wall of the plate body 301, and the spoiler portion 1002 is rotatably arranged at the other end of the deflection portion 1001; the control component 7 passes through one side of the plate body 301 and extends outside the box body 1. The control component 7 has a connecting end, which is arranged on the spoiler portion 1002. The control component 7 is used to drive the spoiler portion 1002 to rotate.

[0044] In the above scheme, the heat exchange plates 3 are arranged parallel to each other, and the cavities 302 between adjacent heat exchange plates are interconnected. Several spoiler strips 10 are arranged at intervals in each cavity 302. The spoiler strip 10 consists of a baffle 1001 and a spoiler 1002. One end of the baffle 1001 is fixed on the inner wall of the heat exchange plate 3 to support the spoiler 1002. The spoiler 1002 is rotatably arranged at the other end of the baffle 1001, and its angle can be changed by driving the control member 7. The control member 7 is installed on the box body 1, and the control member 7 has a connecting end, which is connected to the spoiler 1002. When the plate-fin cooler is working, the spray pipe 2 will spray water onto the heat exchange plate 3, and the baffle 1001 of the spoiler strip 10 in the cavity 302 will change the flow direction of the fluid, increase the turbulence degree and flow path of the fluid, and thus improve the heat exchange efficiency. At the same time, the spoiler 1002 can rotate under the drive of the control member 7, further changing the flow direction and velocity distribution of the fluid, and preventing the fluid from staying in a local area for too long and causing scaling. In addition, the rotation of the spoiler strip 10 can also reduce the deposition of impurities in the fluid on the surface of the heat exchange plate 3, reducing the possibility of scaling. Even if a small amount of scaling occurs after long-term use, the angle of the spoiler 1002 can be adjusted through the control member 7 so that the scaling gradually falls off under the flushing of the fluid, thereby extending the service life of the evaporative plate cooler.

[0045] The setting of the spoiler strip 10 increases the turbulence of the fluid, makes the heat exchange more sufficient, and improves the heat exchange efficiency. The rotation of the spoiler 1002 can change the flow direction and velocity distribution of the fluid, reduce the formation of scale, and reduce the frequency of cleaning. If scaling occurs, the angle of the spoiler 1002 can be adjusted through the control member 7 so that the scale gradually falls off under the flushing of the fluid, which is convenient for maintenance.

[0046] Furthermore, the deflector 1001 is in a straight line shape, the deflector 1001 is obliquely arranged in the cavity 302, and the spoiler 1002 is in a wave shape or an S shape.

[0047] In the above scheme, the linear baffle 1001 has a simple structure and is easy to manufacture and install. In the cavity 302, it can guide the fluid in a relatively direct way to change the flow direction of the fluid. The linear design also allows the baffle 1001 to reduce local stress concentration and improve the stability of the entire structure. The baffle 1001 can also guide the fluid to form a specific flow path in the cavity 302. When the fluid enters the cavity 302 from the inlet, the inclination angle of the baffle 1001 causes the flow direction of the fluid to gradually change, increasing the residence time of the fluid in the cavity 302. The inclined setting can also promote the turbulence of the fluid and improve the heat exchange efficiency. In the process of the fluid flowing along the baffle 1001, it will continuously exchange temperature with the spray water through the heat exchange plate 3, thereby achieving a better evaporation and cooling effect. In addition, this inclined setting also helps to reduce the deposition of impurities in the fluid on the surface of the heat exchange plate 3. Since the flow direction of the fluid is constantly changing, impurities are difficult to accumulate in a fixed position, thereby reducing the possibility of scaling.

[0048] The wavy or S-shaped spoiler 1002 can generate more intense turbulence during the flow of the fluid. This turbulence can break the laminar flow state of the fluid, so that the temperature in the fluid is transferred to the heat exchange plate 3 more quickly, thereby improving the heat exchange efficiency. The complex shape also increases the contact area between the spoiler 1002 and the fluid, further enhancing the heat exchange effect. At the same time, the wavy or S-shaped spoiler 1002 can generate forces in different directions on the fluid at different positions, making the flow of the fluid more chaotic and reducing the formation of local hot spots.

[0049] Furthermore, the spoiler strips 10 are overlapped on the inner wall of the heat exchange plate 3 , and adjacent spoiler strips 10 are arranged in the cavity 302 at staggered intervals. A plurality of spoiler strips 10 form a continuous water flow channel 1003 in the cavity 302 .

[0050] In the above scheme, the spoiler strip 10 is overlapped on the heat exchange plate 3, providing a stable support for the spoiler strip 10. The heat exchange plate 3 usually has a certain strength and rigidity. The spoiler strip 10 is connected thereto by overlapping, and can maintain a stable position during the flow of the fluid, and will not be displaced significantly due to the impact of the fluid. This connection method is also conducive to the transfer of heat. Since the spoiler strip 10 is in direct contact with the heat exchange plate 3, when the fluid flows through the spoiler strip 10 and the heat exchange plate 3, the heat can be transferred between the two more efficiently, which improves the efficiency of heat exchange, thereby improving the heat exchange performance of the entire plate-type cooler. The presence of the spoiler strip 10 makes the flow path of the fluid in the cavity 302 more complicated, and the contact opportunities between the fluid and the heat exchange plate 3 are increased, further improving the heat exchange effect.

[0051] The staggered spacing of adjacent spoiler strips 10 can make the flow of the fluid in the cavity 302 more turbulent. When the fluid flows through the staggered spoiler strips 10, its flow direction changes continuously, forming a strong turbulence. This turbulent state is conducive to breaking the boundary layer of the fluid, promoting heat transfer, and improving heat exchange efficiency. The staggered spacing can also increase the residence time of the fluid in the cavity 302. In the process of bypassing the spoiler strips 10 one by one, the fluid needs to constantly change direction, thereby extending its flow path in the cavity 302, so that the fluid has more time to exchange heat with the heat exchange plate 3. This layout makes the distribution of the fluid in the cavity 302 more uniform. Due to the staggered arrangement of the spoiler strips 10, the fluid will not flow in a certain area, but will be dispersed throughout the cavity 302. This can avoid the occurrence of local overheating or overcooling, and improve the uniformity of heat exchange. At the same time, the staggered spoiler strips 10 can also play a certain role in guiding the flow. When the fluid flows through the spoiler strip 10 , the fluid is guided by the spoiler strip 10 and changes its flow direction, thereby more effectively utilizing the cavity 302 and improving the heat exchange performance of the plate-fin cooler.

[0052] The continuous water flow channel 1003 is conducive to uniform heat transfer. When the fluid flows in the channel, it can fully contact the heat exchange plate 3, so that the heat can be evenly transferred in the entire channel. This uniform heat transfer can avoid local overheating or overcooling, and improve the efficiency and quality of heat exchange. At the same time, the water flow channel 1003 can also be easily cleaned and maintained. Since the fluid flows in the channel, when the plate-type cooler needs to be cleaned, the cleaning liquid can be introduced into the cavity 302 through the water flow channel 1003 to effectively clean the heat exchange plate 3 and the spoiler strip 10.

[0053] Furthermore, the heat exchange plate 3 has a plurality of inclined guide grooves 303, the inclination directions of the deflector 1001 and the spoiler 1002 are opposite to the guide grooves 303, the water flow channel 1003 is connected to the guide grooves 303, and the connection between the water flow channel 1003 and the guide grooves 303 is used to form turbulent water flow.

[0054] In the above scheme, the main function of the guide groove 303 is to guide the flow direction of the fluid on the heat exchange plate 3, increase the contact time and contact area between the fluid and the heat exchange plate 3, and thus improve the heat exchange efficiency. The inclined guide groove 303 can make the fluid produce a certain velocity gradient during the flow process, further enhance the turbulence of the fluid, and promote heat transfer.

[0055] The inclination direction of the baffle 1001 and the spoiler 1002 is opposite to that of the guide groove 303. The reverse inclination design can make the fluid produce a more complex flow state when it flows through the heat exchange plate 3 and the spoiler strip 10. When the fluid flows under the guidance of the guide groove 303, it will be forced to change the flow direction when encountering the reversely inclined baffle 1001 and spoiler 1002, thereby increasing the turbulence of the fluid. The reverse inclination can also cause the fluid to form a more violent impact and stirring effect between the heat exchange plate 3 and the spoiler strip 10, further improving the efficiency of heat exchange. This reverse inclination design can make the fluid form a more uniform temperature distribution in the cavity 302. Since the fluid will continuously change the flow direction and speed when flowing through different parts, the heat can be more evenly transferred to the entire cavity 302, avoiding the occurrence of local overheating or overcooling. At the same time, the reversely inclined baffle 1001 and spoiler 1002 can also increase the contact area between the fluid and the heat exchange plate 3 and the spoiler strip 10, thereby improving the efficiency of heat exchange. When the fluid contacts the reversely inclined parts, more friction and collision will be generated, thereby promoting the transfer of heat. The water flow channel 1003 is connected to the guide groove 303, so that the fluid can form a continuous flow cycle between the heat exchange plate 3 and the spoiler strip 10. It can ensure that the fluid can fully exchange heat in the entire plate-type cooler, thereby improving the heat exchange efficiency. The connection point can also play a role in regulating the flow rate and flow rate of the fluid. By adjusting the connection area between the water flow channel 1003 and the guide groove 303, the flow rate and flow rate of the fluid in different parts can be controlled, thereby optimizing the heat exchange process.

[0056] The connection point can make the fluid flow conversion more smoothly when flowing through the heat exchange plate 3 and the spoiler strip 10. When the fluid enters the guide groove 303 from the water flow channel 1003, or enters the water flow channel 1003 from the guide groove 303, the shape and size of the connection point can guide the flow direction of the fluid, reduce the flow resistance, and improve the fluidity of the fluid. At the same time, the connection point can also promote the mixing and stirring of the fluid. Since the fluids in the water flow channel 1003 and the guide groove 303 have different speeds and directions, they will interact at the connection point, so that the fluids are mixed more evenly, improving the effect of heat exchange. The connection point between the water flow channel 1003 and the guide groove 303 is used to form turbulent water flow. Turbulence is a highly chaotic flow state with high heat and mass transfer efficiency.

[0057] Turbulence can also reduce the thickness of the boundary layer in the fluid, reduce thermal resistance, and allow heat to be transferred to the fluid more quickly. In addition, turbulence can also prevent impurities in the fluid from depositing on the surface of the heat exchange plate 3, reduce the occurrence of scaling, and extend the service life of the plate-fin cooler.

[0058] Furthermore, the box body 1 has a slide groove 703, the control member 7 includes a cylinder 704, the cylinder 704 has an internal thread, and the cylinder 704 is rotatably arranged in the slide groove 703; the screw 701 is threadedly arranged in the cylinder 704, and the screw 701 is hollow; the connecting rope 702 has a plurality of connecting ends, each connecting end corresponds to a spoiler 1002, and one end of the connecting rope 702 located on the outside of the heat exchange plate 3 is penetrated and arranged in the screw 701. After the screw 701 moves along the cylinder 704, the connecting rope 702 pulls the spoiler 1002 to rotate.

[0059] In the above scheme, a positioning beam 13 is also included. The positioning beam 13 is an H-shaped steel beam. The positioning beam 13 is installed in the box body 1 and is mainly used to install and position the heat exchange plate and the control member 7. The positioning beam 13 has a strip groove (not shown in the figure). The strip groove is opened along the length direction of the positioning beam 13, and the width of the strip groove is less than the diameter of the cylinder 704. The screw 701 is threadedly arranged in the cylinder 704, and the screw 701 is hollow. A channel is provided for the connecting rope 702, so that the connecting rope 702 can pass through the screw 701 to achieve the connection and control of the spoiler 1002. The threaded cooperation between the screw 701 and the cylinder 704 determines the movement mode of the screw 701 in the cylinder 704. The pitch and rotation direction of the thread determine the movement direction of the screw 701, thereby affecting the magnitude and direction of the pulling force of the connecting rope 702 on the spoiler 1002. The movement of the screw 701 in the cylinder 704 is driven by the rotation of the cylinder 704. When the cylinder 704 rotates in the chute 703, the screw 701 will move accordingly in the cylinder 704 according to the transmission relationship of the thread. The movement of the screw 701 will cause the connecting rope 702 to generate tension, thereby pulling the spoiler 1002 to rotate. The hollow structure of the screw 701 enables the connecting rope 702 to control the spoiler 1002 without interfering with the thread transmission between the screw 701 and the cylinder 704. This design not only ensures the compactness of the control member 7, but also improves the control accuracy of the spoiler 1002.

[0060] The connecting rope 702 has several connecting ends, each of which corresponds to a spoiler 1002, so that one control member 7 can control the rotation of multiple spoilers 1002 at the same time, thereby improving the control efficiency and the overall performance of the device. One end of the connecting rope 702 located on the outside of the heat exchange plate 3 is arranged in the screw 701, so that the connecting rope 702 can generate tension as the screw 701 moves, thereby pulling the spoiler 1002 to rotate. The main function of the connecting rope 702 is to convert the movement of the screw 701 into tension on the spoiler 1002, thereby realizing the control of the rotation angle of the spoiler 1002. The length and strength of the connecting rope 702 need to be reasonably designed according to the rotation angle of the spoiler 1002 and the required tension to ensure the accuracy and reliability of the control. The multiple connecting ends of the connecting rope 702 can control multiple spoilers 1002 at the same time, so that the rotation angles between the spoilers 1002 can be coordinated and adjusted according to actual needs, further improving the heat exchange efficiency and adaptability of the plate-fin cooler.

[0061] It should be noted that since the spoiler 1002 is S-shaped or wavy, scaling is very likely to occur at the bends. Due to the turbulent effect in the cavity 302, when the water flow flushes the connecting rope 702, it will also drive the connecting rope 702 to shake or swing, thereby achieving slight vibration of the spoiler 1002. Combined with the turbulence of the water flow, the scaling on the spoiler 1002 can be greatly reduced.

[0062] Furthermore, it also includes a heat conductive sheet 9, which is located in the cavity 302 and is arranged on a plurality of deflection portions 1001; a heat sink 8 is arranged on the outside of the box body 1, and the heat sink 8 is connected to the heat conductive sheet 9, and the heat conductive sheet 9 is used to transfer the heat in the cavity 302 to the heat sink 8.

[0063] In the above scheme, the heat conducting sheet 9 is usually made of a material with high thermal conductivity, such as metal copper, aluminum, etc. The heat conducting sheet 9 can quickly transfer heat to the heat sink 8, and the temperature inside the heat exchange plate 3 can be detected by measuring the temperature of the heat conducting sheet 9. The heat sink 8 is usually fixed to the heat conducting sheet 9 by welding, bolting, etc. to ensure a firm and reliable connection.

[0064] Furthermore, the thickness of the heat conducting sheet 9 is smaller than the thickness of the baffle 1001 .

[0065] In the above scheme, the heat conducting sheet 9 usually needs to quickly transfer the heat of the cavity 302. A thinner thickness can reduce thermal resistance, so that heat can be conducted more quickly through the heat conducting sheet 9. In contrast, the baffle 1001 mainly plays the role of changing the flow direction of the fluid, and the requirement for thermal conductivity is relatively low. A thin heat conducting sheet 9 can transfer heat to the heat sink 8 in a shorter time, thereby improving the heat exchange efficiency of the entire cooler.

[0066] Furthermore, the connecting plate 6 is arranged on the heat exchange plate 3 , and the connecting plate 6 has a through groove 601 ; the round rod 4 is horizontally arranged in the box body 1 , and the connecting plate 6 is arranged on the round rod 4 through the through groove 601 .

[0067] In the above solution, when the heat exchange plates 3 need to be separated piece by piece, the heat exchange plates 3 only need to be manually pulled out along the circular tube, so that the outer wall of the heat exchange plates 3 can be cleaned conveniently.

[0068] Furthermore, it also includes a torsion spring 11, which is arranged at the connection between the deflector 1001 and the spoiler 1002, and is used to drive the deflector 1001 to reset.

[0069] In the above scheme, during the operation of the plate-type cooler, the spoiler 1002 may rotate under the action of the control member 7, thereby driving the baffle 1001 to also produce a certain displacement. The main function of the torsion spring 11 is to drive the baffle 1001 to return to the initial position when necessary. When the force of the control member 7 on the spoiler 1002 disappears, the elastic potential energy stored in the torsion spring 11 will be released, generating a torque, causing the baffle 1001 to rotate in the direction of the initial position and return to a normal working state.

[0070] Furthermore, the water inlets 12 of adjacent heat exchange plates 3 are arranged in a staggered manner, the water flow paths in adjacent heat exchange plates 3 are S-shaped, and convex strips 5 are further provided on the outside of the heat exchange plates 3 to increase the area of ​​the spraying water.

[0071] In the above scheme, the S-shaped flow path can fill each heat exchange plate 3, increasing the heat exchange effect between the spray water and the heat exchange plate 3, and the spray water and the exhaust gas can move along the convex strips 5, which not only increases the flow path of the spray water and the exhaust gas, but also improves the cooling effect. A steam trap 14 is also provided between the top of the spray pipe 2 and the bottom of the fan.

[0072] Example 2, refer to Figure 7 The difference between this embodiment and the first embodiment is that the overall length of the heat exchange plate 3 in this embodiment is larger, and the length direction of the heat exchange plate 3 is the same as the length direction of the box body 1. At this time, the water inlet and the water outlet of the heat exchange plate 3 are respectively located on the front and rear surfaces of the box body 1, and the rest of the heat exchange principle is the same as that of the first embodiment.

[0073] It should be noted that, because the pressure inside the heat exchange plate 3 is relatively high after water flows through the heat exchange plate 3, a plurality of protrusions 15 for supporting are provided inside the heat exchange plate 3, and the protrusions 15 can also play a role of spoiler.

[0074] Embodiment 3. The difference between this embodiment and embodiment 1 is that the heat exchange plate 3 in this embodiment is bent. Different from the straight plate structure of the embodiment, the bent heat exchange plate 3 can increase the heat exchange path and improve the heat exchange effect. It should be noted that the layout of the bent heat exchange plate 3 is a conventional technical means and will not be elaborated on here.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
