Description
Technical Field
[0001] This utility model relates to the field of plate heat exchanger technology, specifically to a high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device. Background Technology
[0002] A plate heat exchanger is a common heat exchange device used to transfer heat between fluids. It consists of a series of parallel metal plates, typically made of stainless steel or copper. These plates form an interlaced network of channels. The working principle of a plate heat exchanger is to introduce two fluids into different ports and allow them to flow between the plates. Heat is transferred from one fluid to the other, thus achieving thermal energy transfer. One fluid flows in odd-numbered channels, while the other flows in even-numbered channels. In this way, heat can be transferred between the fluids through the metal plates, achieving heat exchange between them.
[0003] Chinese Utility Model Patent Publication No. CN 221898316 U discloses a plate heat exchanger. The specification describes a plate heat exchanger where multiple fixing blocks are fixedly connected to the outer walls of the plate heat exchanger plates. Multiple threaded rods and limiting nuts are used to fasten the plates together. Multiple spacer washers are fitted onto the outer walls of the threaded rods, with the spacer positioned between adjacent plates. The distance between adjacent plates is equal to the thickness of the spacer, ensuring uniform tightening pressure on the multiple plate heat exchanger gaskets. This not only ensures normal operation of the plate heat exchanger gaskets but also extends their service life. However, this plate heat exchanger lacks a fluid channel structure, failing to increase the flow rate of the cold medium within the channels, resulting in low heat exchange efficiency. Furthermore, the identical structure of the plate heat exchanger plates prevents sufficient contact between the hot and cold media, further reducing heat exchange efficiency and practicality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device, which can effectively solve the problems in the prior art.
[0005] The technical solution adopted by this utility model is: a high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device, including a base and a fixed pressure plate and a movable pressure plate located on the top of the base. Several sets of first plates and second plates are arranged at equal intervals between the fixed pressure plate and the movable pressure plate. A first gasket and a second gasket are respectively provided at the end of the first plate and the second plate near the fixed pressure plate. A first fin and a second fin are respectively fixedly installed at the end of the first plate and the second plate near the fixed pressure plate. A cold medium inlet, a hot medium inlet, a cold medium outlet and a hot medium outlet are fixedly connected to the fixed pressure plate away from the movable pressure plate. A through-hole is opened at the end of the first plate and the second plate near the cold medium inlet. A vertical pump communicating with the cold medium inlet is provided on one side of the base.
[0006] Preferably, connecting blocks are fixedly installed at both ends of the first and second gaskets, and an upper guide rod and a lower guide rod are provided between the fixed pressure plate and the movable pressure plate, which are slidably connected to the connecting blocks. A column is fixedly installed at the end of the upper guide rod and the lower guide rod away from the fixed pressure plate, and several sets of clamping screws are symmetrically arranged at equal intervals on the outer sides of the fixed pressure plate and the movable pressure plate.
[0007] The above technical solution facilitates the rapid installation of the first and second plates through the cooperation of the connecting block with the upper and lower guide rods. Several sets of clamping screws are symmetrically arranged at equal intervals on the outer sides of the fixed and movable clamping plates to ensure the tightness of the connection between each set of the first and second plates, effectively preventing the leakage of hot and cold media mixture.
[0008] Preferably, the first plate and the second plate are provided in several identical groups, with a second plate provided between two adjacent groups of the first plate and a first plate provided between two adjacent groups of the second plate.
[0009] The above technical solution involves setting a second plate between two adjacent sets of first plates and setting a first plate between two adjacent sets of second plates, so that the first and second plates are alternately arranged between the fixed and movable clamping plates, ensuring full contact between the hot and cold media, effectively increasing the heat exchange area, and thus improving the heat exchange efficiency.
[0010] Preferably, the cross-sections of the first and second fins are in a "V" shape, and the number of the second fins is twice the number of the first fins.
[0011] The above technical solution, by setting the cross-section of the first and second fins to a "V" shape, can strongly disturb the fluid flow and promote turbulence, thereby improving heat transfer efficiency. By setting the number of second fins to twice that of the first fins, the cold medium can flow rapidly during the heat exchange process. Conversely, by increasing the number of second fins, the flow rate of the hot medium can be slowed down, which facilitates full contact between the hot and cold media, thereby making the heat exchange efficiency even higher.
[0012] Preferably, the cold medium inlet and the hot medium outlet are located on the upper part of the fixed pressure plate, and the hot medium outlet and the cold medium outlet are located on the lower part of the fixed pressure plate. The radius of the cold medium inlet and the cold medium outlet is larger than the radius of the hot medium inlet and the hot medium outlet.
[0013] The above technical solution, by setting the cold medium inlet and hot medium outlet at the upper part of the fixed pressure plate and the hot medium outlet and cold medium outlet at the lower part of the fixed pressure plate, enables the cold medium and hot medium to flow in opposite directions, thereby improving the heat exchange efficiency. By setting the cold medium inlet and cold medium outlet radii to be larger, the flow resistance of the cold medium is reduced.
[0014] Preferably, the number of the circular holes is equal to the sum of the number of the first plate and the number of the second plate, and multiple sets of the circular holes form a fluid channel.
[0015] By using the above technical solution, the number of circular holes is set to be equal to the sum of the number of the first plate and the second plate, ensuring that the hot and cold media enter the first plate and the second plate respectively.
[0016] Preferably, the fluid conduit includes an inlet section, a contraction section, and an acceleration section, and the orifice of the fluid conduit has a structure that "changes from large to small and then back to large," and the distance from the contraction section to the acceleration section is four times the distance from the inlet section to the contraction section.
[0017] The above technical solution, by setting the orifice of the fluid pipe to "smaller and then larger" structure, allows the orifice to shrink from the inlet section to the contraction section, which facilitates the cold medium to pass through the contraction section and increase the fluid velocity. Furthermore, by setting the distance from the contraction section to the acceleration section to be four times the distance from the inlet section to the contraction section, the flow rate of the fluid in the fluid pipe can be effectively increased, which facilitates the increase of the flow rate of the cold medium, thereby improving the heat exchange efficiency between the cold and hot media.
[0018] Compared with the prior art, this utility model provides a high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device, which has the following beneficial effects:
[0019] 1. This high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device has a fluid pipeline formed by a combination of several sets of circular holes. By setting the structure of the fluid pipeline with the orifice diameter "from large to small and then large again", the orifice diameter narrows from the inlet section to the contraction section, which can facilitate the cold medium to pass through the contraction section and increase the fluid velocity. Furthermore, by setting the distance from the contraction section to the acceleration section to be four times the distance from the inlet section to the contraction section, the flow rate of the fluid in the fluid pipeline can be effectively increased, which can facilitate the increase of the flow rate of the cold medium, thereby improving the heat exchange efficiency between the cold medium and the hot medium.
[0020] 2. This high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device, by setting the cross-section of the first fin and the second fin in a "V" shape, can strongly disturb the fluid flow state, promote the formation of turbulence, and thus improve the heat transfer efficiency. By setting the number of second fins to twice the number of first fins, the cold medium can flow rapidly during the heat exchange process. Conversely, by increasing the number of second fins, the flow rate of the hot medium can be slowed down, which facilitates full contact between the hot and cold media, thereby making the heat exchange efficiency even higher.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1: As Figure 1-5 As shown, this utility model provides a high-efficiency and energy-saving heat exchanger shell enhanced heat transfer device, including a base 1 and a fixed clamping plate 2 and a movable clamping plate 10 located on the top of the base 1. Several sets of first plates 3 and second plates 4 are equally spaced between the fixed clamping plate 2 and the movable clamping plate 10. A first gasket 5 and a second gasket 6 are respectively provided at the end of the first plates 3 and the second plates 4 near the fixed clamping plate 2. A first fin 7 and a second fin 8 are respectively fixedly installed at the end of the first plates 3 and the second plates 4 near the fixed clamping plate 2. A cold medium inlet 15, a hot medium inlet 16, a cold medium outlet 17 and a hot medium outlet 18 are fixedly connected to the fixed clamping plate 2 away from the movable clamping plate 10. A through-hole 19 is opened at the end of the first plates 3 and the second plates 4 near the cold medium inlet 15. A vertical pump 21 communicating with the cold medium inlet 15 is provided on one side of the base 1.
[0029] Specifically, connecting blocks 9 are fixedly installed at both ends of the first gasket 5 and the second gasket 6. An upper guide rod 11 and a lower guide rod 12, slidably connected to the connecting blocks 9, are provided between the fixed clamping plate 2 and the movable clamping plate 10. A column 13 is fixedly installed at the end of the upper guide rod 11 and the lower guide rod 12 away from the fixed clamping plate 2. Several sets of clamping screws 14 are symmetrically arranged at equal intervals on the outer sides of the fixed clamping plate 2 and the movable clamping plate 10. The advantage is that the cooperation between the connecting blocks 9 and the upper and lower guide rods 11 and 12 facilitates the rapid installation of the first plate 3 and the second plate 4. The symmetrical arrangement of several sets of clamping screws 14 at equal intervals on the outer sides of the fixed clamping plate 2 and the movable clamping plate 10 ensures the tightness of the connection between each set of the first plate 3 and the second plate 4, effectively preventing leakage of hot and cold media mixtures.
[0030] Specifically, the first plate 3 and the second plate 4 are arranged in several identical groups, with a second plate 4 positioned between two adjacent groups of first plates 3, and a first plate 3 positioned between two adjacent groups of second plates 4. The advantage is that by positioning the second plate 4 between adjacent groups of first plates 3 and the first plate 3 between adjacent groups of second plates 4, the first plates 3 and second plates 4 are alternately arranged between the fixed pressure plate 2 and the movable pressure plate 10, ensuring sufficient contact between the hot and cold media, effectively increasing the heat exchange area, and thus improving heat exchange efficiency.
[0031] Specifically, the cross-sections of the first fin 7 and the second fin 8 are in a "V" shape, and the number of second fins 8 is twice the number of first fins 7. The advantage is that by setting the cross-sections of the first fins 7 and the second fins 8 in a "V" shape, the "V" shape strongly disturbs the fluid flow, promoting turbulence and thus improving heat transfer efficiency. Furthermore, by setting the number of second fins 8 to twice the number of first fins 7, the rapid flow of the cold medium during heat exchange is facilitated. Conversely, increasing the number of second fins 8 helps to slow down the flow rate of the hot medium, ensuring sufficient contact between the hot and cold media, thereby resulting in higher heat exchange efficiency.
[0032] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.
[0033] Specifically, the cold medium inlet 15 and the hot medium outlet 18 are located on the upper part of the fixed pressure plate 2, while the hot medium outlet 18 and the cold medium outlet 17 are located on the lower part of the fixed pressure plate 2. The radii of the cold medium inlet 15 and the cold medium outlet 17 are larger than the radii of the hot medium inlet 16 and the hot medium outlet 18. The advantage is that by positioning the cold medium inlet 15 and the hot medium outlet 18 on the upper part of the fixed pressure plate 2 and the hot medium outlet 18 and the cold medium outlet 17 on the lower part of the fixed pressure plate 2, the cold and hot media flow in opposite directions, thereby improving heat exchange efficiency. Furthermore, the larger radii of the cold medium inlet 15 and the cold medium outlet 17 reduce the flow resistance of the cold medium.
[0034] Specifically, the number of holes 19 is equal to the sum of the number of the first plate 3 and the second plate 4, and multiple sets of holes 19 form fluid pipes 20. The advantage is that by setting the number of holes 19 to be equal to the sum of the number of the first plate 3 and the second plate 4, it is ensured that hot and cold media enter the first plate 3 and the second plate 4 respectively.
[0035] Specifically, the fluid conduit 20 includes an inlet section 2001, a contraction section 2002, and an acceleration section 2003. The orifice of the fluid conduit 20 has a structure that "decreases and then increases again," and the distance from the contraction section 2002 to the acceleration section 2003 is four times the distance from the inlet section 2001 to the contraction section 2002. The advantage is that by setting the orifice of the fluid conduit 20 to "decreases and then increases again," the orifice narrows from the inlet section 2001 to the contraction section 2002, facilitating the increase in fluid velocity of the cold medium through the contraction section 2002. Furthermore, by setting the distance from the contraction section 2002 to the acceleration section 2003 to be four times the distance from the inlet section 2001 to the contraction section 2002, the flow rate of the fluid in the fluid conduit 20 can be effectively increased, facilitating the increase in the flow rate of the cold medium, thereby improving the heat exchange efficiency between the cold and hot media.
[0036] Working principle: During use, the connecting block 9, in conjunction with the upper guide rod 11 and the lower guide rod 12, facilitates the quick installation of the first plate 3 and the second plate 4. Several sets of clamping screws 14 are symmetrically arranged at equal intervals on the outer sides of the fixed clamping plate 2 and the movable clamping plate 10, ensuring the tightness of the connection between each set of the first plate 3 and the second plate 4, effectively preventing leakage of hot and cold media. The arrangement of a second plate 4 between adjacent sets of first plates 3 and a first plate 3 between adjacent sets of second plates 4 allows the first plate 3 and the second plate 4 to alternate between the fixed clamping plate 2 and the movable clamping plate 10, ensuring sufficient mixing of hot and cold media. Contact effectively increases the heat exchange area, thereby improving heat exchange efficiency. By setting the number of circular holes 19 to be equal to the sum of the number of the first plate 3 and the second plate 4, it is ensured that the cold and hot media enter the first plate 3 and the second plate 4 respectively. The cold media, driven by the vertical pump 21, enters the device from the cold media inlet 15 at the top of the fixed pressure plate 2, while the hot media flows in autonomously from the hot media inlet 16 at the bottom of the fixed pressure plate 2. By setting the orifice diameter of the fluid pipe 20 to "smaller and then larger" structure, the orifice diameter narrows from the inlet section 2001 to the contraction section 2002, which facilitates the cold media to pass through the contraction section 2002 and increase the fluid velocity. Furthermore, by setting... The distance from the contraction section 2002 to the acceleration section 2003 is four times the distance from the inlet section 2001 to the contraction section 2002, which can effectively increase the flow rate of the fluid in the fluid pipe 20, facilitating the increase of the flow rate of the cold medium, thereby improving the heat exchange efficiency between the cold and hot media. By setting the cross-section of the first fin 7 and the second fin 8 to a "V" shape, the "V" shape can strongly disturb the fluid flow state, promoting the formation of turbulence, thereby improving the heat transfer efficiency. By setting the number of second fins 8 to twice the number of first fins 7, the rapid flow of the cold medium can be achieved during the heat exchange process. Conversely, by increasing the number of second fins 8... The fins 8 facilitate slowing down the flow rate of the hot medium and ensure full contact between the hot and cold media, thereby increasing the heat exchange efficiency. After heat exchange is completed, the cold medium that has absorbed heat is discharged from the cold medium outlet 17 at the bottom of the fixed pressure plate 2, and the hot medium that releases heat is discharged from the hot medium outlet 18 at the top. By setting the cold medium inlet 15 and the hot medium outlet 18 at the top of the fixed pressure plate 2 and the hot medium outlet 18 and the cold medium outlet 17 at the bottom of the fixed pressure plate 2, the cold and hot media form a counter-flow, thereby improving the heat exchange efficiency. By setting the cold medium inlet 15 and the cold medium outlet 17 to have larger radii, the flow resistance of the cold medium is reduced.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
