Description

TECHNICAL FIELD

[0001] The application relates to the technical field of heat exchangers, in particular to a novel elliptical corner hole plate shell type heat transfer plate. BACKGROUND

[0002] The plate shell type heat exchanger is a kind of heat exchanger composed of a plate bundle and a shell, which combines the advantages of the tube shell type and the plate type heat exchanger, has high heat transfer efficiency, strong universality, reliable sealing mode, light weight, small volume, multiple process structures and the like, and is widely applied to the industrial departments such as chemical industry, petroleum, medicine, food, energy and power and papermaking.

[0003] At present, the plate shell type heat exchanger is composed of a circular plate shell type heat transfer plate. Due to the circular structure of the guide hole in the traditional circular plate, the distance between two circular interfaces is short, and the fluid distribution is uneven. Meanwhile, the effective heat transfer area is large, which increases the heat transfer area and easily causes the phenomena of low heat transfer efficiency and uneven heating of the heat transfer plate surface, reduces the heat transfer efficiency and affects the heat transfer effect. SUMMARY

[0004] In order to solve the problems of low heat transfer efficiency and large heat transfer area of the circular plate shell type plate, the application provides a novel elliptical corner hole plate shell type heat transfer plate.

[0005] The novel elliptical corner hole plate shell type heat transfer plate provided by the application adopts the following technical scheme:

[0006] A novel elliptical corner hole plate shell type heat transfer plate, comprising a plate body, the plate body is circular, a fluid inlet and a fluid outlet are formed on the plate body, a plurality of corrugations are formed on the plate body, and the fluid inlet and the fluid outlet are both elliptical.

[0007] By adopting the above technical scheme, the circular plate body makes the fluid uniformly distributed on the plate, the elliptical fluid inlet and the fluid outlet further optimize the flow path of the fluid, and the flow resistance is reduced. The plurality of corrugations formed on the plate body make the heat transfer area moderate, the heat transfer effect is enhanced, stable work under large flow is realized, the deformation caused by thermal stress is effectively resisted, the distribution area is increased, and the heat transfer efficiency is improved.

[0008] Preferably, the ratio of the major axis to the minor axis of the elliptical fluid inlet and the fluid outlet is 2:1.

[0009] By adopting the above technical scheme, the fluid inlet and the fluid outlet are designed to be elliptical with the ratio of the major axis to the minor axis being 2:1, so that the heat exchanger area is reduced and the metal material consumption is saved under the same heat transfer condition.

[0010] Preferably, the diameter of the plate body is 0.319m-1.181m, the thickness of the plate body is 0.6mm-1mm, the corrugation depth of the plate body is 2.4mm-4.15mm, and the corrugation pitch of the plate body is 12mm-18mm.

[0011] By adopting the above technical solution, the diameter of the plate body is in the range of 0.319m-1.181m, which is convenient to adapt to different size requirements of the heat exchanger, ensures that the flow path of the fluid on the plate is long enough, and thus improves the heat transfer efficiency. The thickness of the plate body is in the range of 0.6mm-1mm, which can not only ensure the strength of the plate, but also effectively reduce the thermal resistance and improve the heat transfer efficiency. The corrugation depth of the plate body is in the range of 2.4mm-4.15mm, the corrugation structure can increase the stability of fluid flow, and improve the heat transfer coefficient. The corrugation pitch is in the range of 12mm-18mm, and the reasonable setting of the corrugation pitch ensures that the fluid flows more uniformly between the corrugations, avoiding the phenomenon of local overheating or overcooling.

[0012] Preferably, the corrugation shape of the plate body is oblique one or multiple chevron shape.

[0013] By adopting the above technical solution, the oblique one chevron corrugation can make the fluid flow uniformly on the surface of the plate, and the multiple chevron corrugation can make the fluid more uniformly distributed on the surface of the plate through multiple intersection points, thereby improving the heat transfer efficiency. By optimizing the fluid flow path, the flow dead angle is reduced, the plate surface is uniformly heated, and the heat transfer efficiency and effect are further improved.

[0014] Preferably, the plate body is a 304 stainless steel plate, a 316L stainless steel plate, a 254SMo stainless steel plate, a 904L stainless steel plate, or a nickel-chromium steel plate.

[0015] By adopting the above technical solution, the plate body selects 304 stainless steel plate, 316L stainless steel plate, 254SMo stainless steel plate, 904L stainless steel plate, or nickel-chromium steel plate material, so that the heat transfer plate can improve the heat transfer efficiency and increase the service life in different application environments, and further improve the resistance and reliability of the plate and shell heat transfer plate in different environments.

[0016] Preferably, the ratio of the diameter of the plate body to the length of the line connecting the center points of the fluid inlet and the fluid outlet is 1.36:1 to 1.44:1.

[0017] By adopting the above technical solution, the ratio of the diameter of the plate body to the length of the line connecting the center points of the fluid inlet and the fluid outlet is adjusted to 1.36:1 to 1.44:1, the fluid distribution is further optimized, the fluid flow is uniform, and thus the heat transfer efficiency is improved, and the heat transfer effect is better.

[0018] Preferably, the included angle of the herringbone-shaped ripples is 100°.

[0019] By adopting the above technical solution, the included angle of the herringbone corrugations is 100°, which further improves the distribution of fluid on the plate surface, allowing the fluid to flow evenly across the entire plate surface, avoiding dead corners formed on the plate surface, and facilitating consistency and stability during the production process of the heat transfer plate, thereby improving heat transfer efficiency.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The elliptical fluid inlet and outlet further optimize the fluid flow path, making it easier to reduce flow resistance. The corrugations formed on the plate body make the heat transfer area moderate, thereby enhancing the heat transfer effect, enabling stable operation under high flow rates, effectively resisting deformation caused by thermal stress, and increasing the distribution area to improve heat transfer efficiency.

[0022] 2. By designing the fluid inlet and outlet as elliptical shapes with a major axis to minor axis ratio of 2:1, the heat exchanger area can be reduced and the consumption of metal materials can be saved under the same heat transfer conditions.

[0023] 3. By adjusting the ratio of the diameter of the plate body to the length of the line connecting the center points of the fluid inlet and the fluid outlet to 1.36:1 to 1.44:1, the fluid distribution is further optimized to avoid uneven fluid flow, thereby improving the heat transfer efficiency and making the heat transfer effect better.
