Pressure-bearing enhanced corrugated plate

Abstract

The invention provides a pressure-bearing enhanced corrugated plate. The corrugated plate is of a rectangular structure. The length-width ratio of the rectangular structure satisfies the equation that L / W=2.8~3.0. The corrugated plate is composed of five parts including edge supporting regions, sealing regions located on the inner sides of the edge supporting regions, a middle heat transfer region, flow guide regions at the two ends of the heat transfer region and pipe opening regions, wherein each pipe opening region is located on one side of the corresponding flow guide region. The pressure-bearing enhanced corrugated plate has high heat transfer performance, low flow resistance performance and high circulation performance, the pressure-bearing capacity is remarkably improved, and the corrugated plate is suitable for the working conditions with the pressure intensity below 3.0 MPa or with the large pressure fluctuation.

Description

technical field [0001] The invention relates to the field of design, development, processing and manufacturing of heat transfer elements of heat exchange equipment, in particular to a pressure-bearing reinforced corrugated plate of a detachable plate heat exchanger. Background technique [0002] The detachable plate heat exchanger has the advantages of high heat transfer efficiency, small footprint, convenient disassembly and washing installation, economy and energy saving, etc. The shortcomings of the device are also obvious, the working pressure is lower than 2.5MPa, and the pressure fluctuation is small. [0003] At present, most of the plate types used in China can only be used for working conditions below 2.0MPa, and the pressure bearing capacity of the plates is poor, which seriously limits the application of detachable plate heat exchangers. In order to improve the pressure bearing performance of the whole machine and prevent leakage, the usual practice is to reduce ...

Problems solved by technology

[0002] The detachable plate heat exchanger has the advantages of high heat transfer efficiency, small footprint, convenient disassembly and washing installation, economy and energy saving, etc. The shortcomings of the device are also obvious, the working pressure is lower than 2.5MPa, and the pressure fluctuation is small

[0003] At present, most of the plate types used in China can only be used for working conditions below 2.0MPa, and the pressure bearing capacity of the plates is poor, which seriously limits the application of detachable plate heat exchangers

In order to improve the pressure bearing performance of the whole machine and prevent leakage, the usual practice is to reduce the compaction size, which will cause serious deformation of the plates and corrugations, the plates cannot be reused, and shorten the service life, heat transfer performance and passability of the equipment. Problems such as not reaching the design index; or increasing the thickness of the plate, which will significantly increase the production cost
