Background Art

[0002] A plate heat exchanger is a heat exchange device composed of a series of stacked corrugated metal sheets, which use plates to exchange heat. However, due to the current working mode and single structure of the heat exchange plate, the following problems are caused: First, the turbulence effect is poor and easy to be blocked. Traditional plate heat exchangers are prone to dead zones in certain areas, and the water flow cannot become turbulent, so the mud and sand are deposited in the dead zones and gradually spread to the entire plate, thereby reducing the heat exchange efficiency; second, the sealing is poor. Sealing strips need to be set around the entire periphery of the plate and around the corner holes. Under the impact of long-term fluid media, local displacement or damage is prone to occur, causing the sealing strip to fail and leak.

[0003] Therefore, in view of the common problems of poor turbulence effect, easy clogging and poor sealing of existing heat exchange plates in use, comprehensive consideration should be given to the working mode and structure of the heat exchange plate to design a heat exchange plate that can increase turbulence, prevent clogging and improve sealing.

[0009] The present invention realizes uniform turbulence and diffusion of the fluid through a uniform turbulence and dispersion device, that is, the initial turbulence and uniform radial diffusion of the fluid are realized through the turbulence balls in the uniform turbulence and dispersion device; realizes multi-layer vortex and turbulent motion of the fluid through a multi-layer vortex and turbulent device, that is, the multi-layer vortex and turbulent motion are realized through the spoiler plates and spoiler strips in the multi-layer turbulence and turbulent device; realizes uniform turbulence and collection of the fluid through a uniform turbulence and collection device, that is, the turbulence and uniform radial collection of the fluid are realized through the turbulence balls in the uniform turbulence and dispersion device; realizes the positioning of the heat exchange plate and the guidance of the fluid through a positioning and guiding device, that is, the positioning and diversion are realized through the diversion blocks in the positioning and guiding device, and the guided flow of the fluid is realized through the diversion blocks and the guide plates; prevents the relative movement of the heat exchange plate and realizes multi-edge curvature sealing through an anti-curvature sealing device, that is, the movement of the sealing strip is prevented through the convex blocks on the sealing groove of the anti-curvature sealing device, and multi-edge curvature sealing is realized through the convex strips on the sealing strip.

[0010] The present invention realizes uniform turbulent flow and diffusion of the fluid through a uniform turbulent flow diffusion device, that is, the preliminary turbulence and uniform radial diffusion of the fluid are realized through the turbulent balls in the uniform turbulent flow diffusion device. Specifically, when the turbulent plate is working, taking the hot plate as an example, the fluid enters from the hot flow inlet, and before flowing into the main inlet and the secondary inlet, it needs to pass through the turbulent balls arranged in a radial arc shape. Since the turbulent balls are distributed in a radial arc shape, the fluid flows in a dispersed manner on both sides of the turbulent balls and forms a uniform diffuse flow, and forms turbulent heat exchange under the obstruction of the turbulent body. In addition, part of the fluid flows over the turbulent body, and the fluid forms vortices in front of and behind the turbulent body, thereby realizing preliminary turbulent flow heat exchange.

[0011] The present invention designs and punches the spoiler ball. The punching process not only saves materials and reduces costs, but also enables the spoiler ball and the heat exchange plate to be made of the same material and have the same thermal characteristics.

[0012] The present invention arranges the spoiler balls to be in a radial arc shape and to be distributed at equal intervals. This design enables the fluid to be uniformly dispersed radially to the main inlet and the secondary inlet through the spoiler body.

[0013] The present invention provides a flow disturbance ball in the flow-dispersing device. This design realizes the initial flow disturbance of the fluid, which not only makes the fluid contact with the heat exchange plate in multiple dimensions, but also prolongs the flow time of the fluid in the flow-dispersing device, thereby improving the heat exchange efficiency.

[0014] The present invention provides a main inlet and a secondary inlet in the center and on both sides below the uniformly disturbed diffuser, respectively. Through this multi-inlet design, the fluid can enter the multi-layer vortex turbulence device from multiple directions, and the heat exchange area is fully covered, thereby achieving heat exchange without blind spots and improving heat exchange efficiency.

[0015] The present invention sets the inner diameter of the main inlet to twice the inner diameter of the secondary inlet. Through this design, the fluids on both sides are pressurized through the secondary inlet and enter the multi-layer vortex device, thereby forming a strong vortex and improving the heat exchange efficiency.

[0016] The present invention realizes multi-layer vortex and turbulent motion of the fluid through a multi-layer vortex turbulence device, that is, multi-layer vortex and turbulent motion is realized through spoilers and spoiler strips in the multi-layer vortex turbulence device. Specifically, when the heat exchange plate is working, taking the heat plate as an example, when the fluid enters the multi-layer vortex turbulence device through the main inlet and the secondary inlet, the fluid forms a vortex flow under the action of the spoiler plate, and forms a turbulent motion under the action of the spoiler strip. Under the alternating arrangement of the spoiler plates and the spoiler strips, the fluid forms multi-layer vortex and turbulence, and the fluid time of the fluid in the multi-layer vortex turbulence device is extended, so that the fluid is prompted to fully contact with the heat exchange plate, thereby improving the heat exchange efficiency.

[0017] The invention designs and punches the spoiler plate and the spoiler strip. The punching process not only saves materials and reduces costs, but also enables the spoiler plate, the spoiler strip and the heat exchange plate to be made of the same material and have the same thermal characteristics.

[0018] The present invention sets the spoiler in an arc shape. Through this design, the fluid forms a vortex at the spoiler, and the vortex is used to fully exchange heat in the fluid, thereby improving the heat exchange efficiency.

[0019] The present invention provides a trapezoidal through groove in the middle of the spoiler. Through this design, the fluid is pressurized and flows out through the through groove and impacts the downwardly emitted fluid, thereby preventing the fluid from laminar flow and making the fluid always flow in a turbulent state in the multi-layer vortex turbulence device.

[0020] The present invention provides a spoiler strip with a triangular structure in longitudinal section. This design realizes fluid disturbance, enables the fluid to flow in a turbulent state and contact the heat exchange plate in multiple dimensions, thereby improving heat exchange efficiency.

[0021] The present invention arranges the spoiler plates and spoiler strips in an inverted triangle alternating arrangement. This design realizes layered vortex and turbulence of the fluid, promotes the fluid to fully contact the heat exchange plate, and improves the heat exchange efficiency.

[0022] The present invention realizes uniform turbulence and convergence of the fluid through a uniform turbulence and flow collection device, that is, the turbulence and uniform radial convergence of the fluid are realized through the turbulence balls in the uniform turbulence and flow dispersion device. Specifically, when the spoiler plate is working, taking the hot plate as an example, the fluid enters from the hot flow outlet, and before flowing into the hot flow outlet, it needs to pass through the turbulence balls arranged in a radial arc shape again. Since the turbulence balls are distributed in a radial arc shape, the fluid is recovered radially, and the fluid flows in a dispersed manner on both sides of the turbulence balls to form a uniform convergence flow, and forms turbulent heat exchange under the obstruction of the turbulence fluid. In addition, part of the fluid flows over the turbulence fluid, and the fluid forms vortices in front of and behind the turbulence fluid, thereby realizing turbulence heat exchange again.

[0023] The present invention realizes the positioning of the heat exchange plate and the guiding of the fluid through the positioning and guiding device, that is, the positioning and diversion are realized through the diversion block in the positioning and guiding device, and the guided flow of the fluid is realized through the diversion block and the guide plate. Specifically, when the spoiler plate is working, the hot plate and the cold plate are installed and positioned respectively through the diversion blocks thereon during installation, and the diamond-shaped diversion block also plays a role in diverting the fluid at the main inlet; the guide block guides the fluid flowing through the spoiler ball, prompting the fluid to flow toward the main inlet and the secondary inlet, and the guide plate guides the fluid at the secondary inlet, so that the fluid is guided to flow toward the spoiler below, which is convenient for the formation of vortex at the spoiler below the fluid.

[0024] The present invention sets the diverter block as a diamond structure. This design not only realizes low-resistance diversion of the fluid, but also realizes stable positioning of the heat exchange plate, that is, the inner edge of the diamond is used to prevent the hot plate and the cold plate from moving relative to each other.

[0025] The present invention provides a rubber block at the joint of the hot plate diverter block and the cold plate diverter block. This design reduces the noise of the heat exchange plate, that is, the vortex and turbulent impact kinetic energy of the fluid on the hot plate and the cold plate is consumed by the rubber block, thereby reducing the noise of the heat exchange plate.

[0026] The present invention sets the guide plate as a three-section folded plate structure, and realizes the guided flow of the fluid through this design, that is, the three-section folded plate is used to realize the path guidance of the fluid.

[0027] The present invention prevents the relative movement of the heat exchange plate and realizes multi-edge maze sealing through an anti-movement sealing device, that is, the convex blocks on the sealing groove of the anti-movement sealing device are used to prevent the sealing strip from moving, and the convex strips on the sealing strip realize multi-edge maze sealing. Specifically, when the spoiler is working, taking the heat plate as an example, the convex blocks on the sealing groove cooperate with the concave holes on the sealing strip, and the square convex blocks and concave holes can prevent both relative rotation and relative movement, thereby preventing the sealing strip from moving and eliminating fluid leakage in the sealing strip; the multiple convex strips on the sealing strip form a multi-edge seal, and each edge is equivalent to a sealing strip. In addition, the gaps between the convex strips can temporarily store part of the leaked fluid, and the multiple convex strip gaps realize multi-edge sealing for the fluid once leaked, thereby improving the sealing efficiency.

[0028] The present invention symmetrically arranges three equidistant convex strips on the left and right sides of the sealing strip, respectively. This design improves the sealing efficiency, that is, the convex strips for sealing and extrusion can not only realize multi-edge sealing, but also temporarily store the leaked fluid through the gaps between the convex strips, and the gaps between the multiple convex strips realize the tortuous flow of the leaked fluid, thereby preventing the fluid from leaking out directly.

[0029] The present invention sets the sealing groove protrusion and the sealing strip concave hole as square hole structures respectively. This design can prevent the sealing strip from moving in four directions and from rotating relatively, thereby preventing the sealing strip from reducing the sealing performance due to fluid impact and causing leakage of the heat exchange plate.

[0030] The beneficial effects of the present invention are: uniform turbulence diffusion of the fluid is achieved through the uniform turbulence dispersion device, multi-layer vortex and turbulent motion of the fluid is achieved through the multi-layer vortex turbulence device, uniform turbulence collection of the fluid is achieved through the uniform turbulence collection device, positioning of the heat exchange plate and flow guidance of the fluid are achieved through the positioning and flow guidance device, and relative movement of the heat exchange plate is prevented and multi-edge curved diameter sealing is achieved through the anti-curving sealing device.

[0045] Combination Figure 3 and Figure 4As shown, the uniformly disturbed and diffused flow device is mainly composed of a spoiler ball 2, a main inlet 13 and a secondary inlet 11. The spoiler ball 2 of the uniformly disturbed and diffused flow device is located above the main inlet 13 and the secondary inlet 11, and the main inlet 13 and the secondary inlet 11 are respectively located in the center and on both sides of the bottom of the uniformly disturbed and diffused flow device.

[0046] The spoiler ball 2 is stamped by the heat exchange plate 8, and is hemispherical. The spoiler ball 2 is in a radial arc shape and is distributed at equal intervals. The main inlet 13, the secondary inlet 11 and the main outlet 17 are square structures respectively. The inner diameter value of the main inlet 13 is the same as the inner diameter value of the main outlet 17. The inner diameter value of the main inlet 13 is twice the inner diameter value of the secondary inlet 11. There are two secondary inlets 11 and they are arranged on both sides of the main inlet 13 on opposite sides.

[0047] The present invention realizes uniform turbulent flow and diffusion of the fluid through a uniform turbulent flow diffusion device, that is, the preliminary turbulence and uniform radial diffusion of the fluid are realized through the turbulent ball 2 in the uniform turbulent flow diffusion device. Specifically, when the spoiler 3 is working, taking the hot plate 8 as an example, the fluid enters from the hot flow inlet 6, and before flowing into the main inlet 13 and the secondary inlet 11, it needs to pass through the turbulent ball 2 arranged in a radial arc shape. Because the turbulent ball 2 is distributed in a radial arc shape, the fluid is dispersed and flows through the two sides of the turbulent ball 2 to form a uniform diffusion flow, and forms turbulent heat exchange under the obstruction of the turbulent body. In addition, part of the fluid flows over the turbulent body, and the fluid forms eddies in front of and behind the turbulent body, thereby realizing preliminary turbulent flow heat exchange.

[0048] The present invention designs and manufactures the spoiler ball 2 by stamping. This stamping process not only saves materials and reduces costs, but also enables the spoiler ball 2 and the heat exchange plate 8 to be made of the same material and have the same thermal characteristics.

[0049] In the present invention, the spoiler balls 2 are arranged in a radial arc shape and are distributed at equal intervals. This design enables the fluid to be uniformly dispersed radially to the main inlet 13 and the secondary inlet 11 through the spoiler.

[0050] The present invention provides a flow disturbance ball 2 in the flow-dispersing device. This design realizes the initial flow disturbance of the fluid, which not only makes the fluid contact with the heat exchange plate 8 in multiple dimensions, but also prolongs the flow time of the fluid in the flow-dispersing device, thereby improving the heat exchange efficiency.

[0051] The present invention provides a main inlet 13 and a secondary inlet 11 in the center and on both sides below the uniformly disturbed flow device, respectively. Through this multi-inlet design, the fluid can enter the multi-layer vortex turbulence device from multiple directions, and the heat exchange area is fully covered, thereby realizing heat exchange without blind spots and improving heat exchange efficiency.

[0052] The present invention sets the inner diameter of the main inlet 13 to be twice the inner diameter of the secondary inlet 11. Through this design, the fluids on both sides are pressurized through the secondary inlet 11 and enter the multi-layer turbulent device, thereby forming a strong vortex and improving the heat exchange efficiency.

[0054] The spoiler 3 and the spoiler strip 4 are stamped by the heat exchange plate 8. The spoiler 3 is in an arc shape, and a through groove is opened in the middle of the spoiler 3. The cross-section of the through groove in the middle of the spoiler 3 is a trapezoidal structure that is narrow at the top and wide at the bottom. 36 spoilers are grouped together and arranged in an inverted triangle; the spoiler strip 4 is in a long strip shape, and the longitudinal section of the spoiler strip 4 is triangular. 42 spoiler strips are grouped together and arranged in an inverted triangle. A gap is provided between two spoiler strips 4, and the cross-section of the gap of the spoiler strip 4 is a trapezoidal structure that is narrow at the top and wide at the bottom. The six spoiler plates 3 and the two spoiler strips 4 are arranged alternately in sequence.

[0055] The present invention realizes multi-layer vortex and turbulent motion of the fluid through a multi-layer vortex device, that is, multi-layer vortex and turbulent motion are realized through the spoiler 3 and spoiler strips 4 in the multi-layer vortex device. Specifically, when the heat exchange plate 8 is working, taking the heat plate 8 as an example, when the fluid enters the multi-layer vortex device through the main inlet 13 and the secondary inlet 11, the fluid forms a vortex flow under the action of the spoiler 3, and forms a turbulent motion under the action of the spoiler strips 4. Under the alternating arrangement of the spoiler plates 3 and the spoiler strips 4, the fluid forms multi-layer vortices and turbulence, and prolongs the fluid time in the multi-layer vortex device, so that the fluid is fully in contact with the heat exchange plate 8, thereby improving the heat exchange efficiency.

[0056] The present invention designs and manufactures the spoiler 3 and the spoiler strip 4 by stamping. This stamping process not only saves materials and reduces costs, but also enables the spoiler 3, the spoiler strip 4 and the heat exchange plate 8 to be made of the same material and have the same thermal characteristics.

[0057] The present invention sets the spoiler 3 to be in an arc shape. Through this design, the fluid forms a vortex at the spoiler 3, and the vortex is used to fully exchange heat in the fluid, thereby improving the heat exchange efficiency.

[0058] The present invention provides a trapezoidal through groove in the middle of the spoiler 3. Through this design, the fluid is pressurized and flows out through the through groove and impacts the downwardly emitted fluid, thereby preventing the fluid from laminar flow and making the fluid always flow in a turbulent state in the multi-layer vortex turbulence device.

[0059] The present invention provides the spoiler strip 4 with a triangular structure in longitudinal section. This design realizes fluid turbulence, allowing the fluid to flow in a turbulent state and contact the heat exchange plate 8 in multiple dimensions, thereby improving heat exchange efficiency.

This design realizes layered vortex and turbulence of the fluid, which promotes the fluid to fully contact the heat exchange plate 8 and improves the heat exchange efficiency.

[0061] Combination Figure 7As shown, the flow-disturbing and collecting device mainly consists of a flow-disturbing ball 2 and a main outlet 17. The flow-disturbing ball 2 of the flow-disturbing and collecting device is located below the main outlet 17, and the main outlet 17 is located in the center above the flow-disturbing and collecting device.

[0062] The present invention realizes uniform turbulence and convergence of the fluid through a uniform turbulence and flow collection device, that is, the turbulence and uniform radial convergence of the fluid are realized through the spoiler ball 2 in the uniform turbulence and flow dispersion device. Specifically, when the spoiler plate 3 is working, taking the hot plate 8 as an example, the fluid enters from the hot flow outlet 1, and before flowing into the hot flow outlet 1, it needs to pass through the spoiler ball 2 arranged in a radial arc shape again. Because the spoiler ball 2 is distributed in a radial arc shape, the fluid is recovered radially, and the fluid flows through the two sides of the spoiler ball 2 in a dispersed manner to form a uniform convergence flow, and forms turbulent heat exchange under the obstruction of the turbulent fluid. In addition, part of the fluid flows over the turbulent fluid, and the fluid forms vortices in front of and behind the turbulent fluid, thereby realizing turbulent heat exchange again.

[0063] Combination Figure 8 As shown, the positioning and guiding device is mainly composed of a diverter block 12, a guide block 14 and a guide plate 15. The diverter block 12, the guide block 14 and the guide plate 15 are stamped by the heat exchange plate 8. The diverter block 12 has a diamond structure. The diverter block 12 is located in the middle of the main inlet 13 and the main outlet 17. The diverter block 12 of the hot plate 8 and the diverter block 12 of the cold plate 10 are matched and a rubber block 18 is provided at the matching position. The guide block 14 is located between the main inlet 13 and the secondary inlet 11 and its longitudinal section is triangular. The guide plate 15 is a 3-section folded plate structure, and the guide plate 15 is located at the secondary inlet 11.

[0064] The present invention realizes the positioning of the heat exchange plate 8 and the guiding of the fluid through the positioning and guiding device, that is, the positioning and diversion are realized through the diverter block 12 in the positioning and guiding device, and the guiding flow of the fluid is realized through the diverter block 14 and the guide plate 15. Specifically, when the spoiler 3 is working, the hot plate 8 and the cold plate 10 are installed and positioned respectively through the diverter blocks 12 thereon during installation, and the diamond-shaped diverter block 12 also plays a role in diverting the fluid at the main inlet 13; the guide block 14 guides the fluid flowing through the spoiler ball 2, prompting the fluid to flow toward the main inlet 13 and the secondary inlet 11, and the guide plate 15 guides the fluid at the secondary inlet 11, so that the fluid is guided to flow toward the spoiler 3 below, which is convenient for the fluid to form a vortex at the spoiler 3 below.

[0065] The present invention sets the diverter block 12 as a diamond structure. This design not only realizes low-resistance diversion of the fluid, but also realizes stable positioning of the heat exchange plate 8, that is, the inner edge of the diamond is used to prevent the hot plate 8 and the cold plate 10 from moving relative to each other.

[0066] The present invention provides a rubber block 18 at the joint of the hot plate 8 diverter block 12 and the cold plate 10 diverter block 12. This design reduces the noise of the heat exchange plate 8, that is, the vortex and turbulent impact kinetic energy of the fluid on the hot plate 8 and the cold plate 10 is consumed by the rubber block 18, thereby reducing the noise of the heat exchange plate 8.

[0067] The present invention sets the guide plate 15 as a three-section folded plate structure. This design is used to guide the flow of the fluid, that is, the three-section folded plate is used to guide the path of the fluid.

[0068] Combination Fig. 9 , Fig.10 and Fig.11 As shown, the anti-bending seal device is mainly composed of a sealing groove 20 and a sealing strip 5. The sealing groove 20 is provided with a protrusion 19, and the sealing strip 5 is provided with a protrusion 21 and a concave hole 16. The sealing strip 5 is installed in the sealing groove 20.

[0069] The inner sides of the sealing groove 20 are respectively provided with an inverted trapezoidal structure with a larger inner side and a smaller outer side. The protrusions 19 are square structures and are arranged at equal intervals on the inverted trapezoidal structure inside the sealing groove 20. The sealing strip 5 is in a "mountain" shape. The recessed holes 16 on the sealing strip 5 are square structures and are arranged at equal intervals. The protrusions 19 of the sealing groove 20 are installed in the recessed holes 16 of the sealing strip 5. Three equally spaced protrusions 21 are symmetrically provided on the left and right sides of the sealing strip 5.

[0070] The present invention prevents the relative movement of the heat exchange plate 8 and realizes multi-edge maze sealing through the anti-maze sealing device, that is, the convex block 19 on the sealing groove 20 of the anti-maze sealing device prevents the sealing strip 5 from moving, and the convex strips 21 on the sealing strip 5 realize multi-edge maze sealing. Specifically, when the spoiler 3 is working, taking the heat plate 8 as an example, the convex block 19 on the sealing groove 20 cooperates with the concave hole 16 on the sealing strip 5. The square convex block 19 and the concave hole 16 can prevent both relative rotation and relative movement, thereby preventing the sealing strip 5 from moving and eliminating fluid leakage in the sealing strip 5; the multiple convex strips 21 on the sealing strip 5 form a multi-edge seal, each edge is equivalent to a sealing strip 5, and in addition, the gaps between the convex strips 21 can temporarily store part of the leaked fluid, and the gaps between the multiple convex strips 21 realize multi-edge sealing for the fluid once leaked, thereby improving the sealing efficiency.

[0071] The present invention symmetrically provides three equidistant convex strips 21 on the left and right sides of the sealing strip 5, respectively. This design improves the sealing efficiency, that is, the sealing extruded convex strips 21 can not only realize multi-edge sealing, but also temporarily store the leaked fluid through the gaps between the convex strips 21, and the gaps between the multiple convex strips 21 realize the tortuous flow of the leaked fluid, preventing the fluid from leaking out directly.

[0072] The present invention sets the protrusion 19 of the sealing groove 20 and the recessed hole 16 of the sealing strip 5 as square hole structures respectively. This design can prevent the sealing strip 5 from moving in four directions and from rotating relatively, thereby preventing the sealing strip 5 from reducing its sealing performance due to fluid impact and causing leakage of the heat exchange plate 8.
