Abstract
The utility model discloses a corrugated plate, which is characterized in that the plate is a rectangular plate with herringbone corrugation. The corrugation on the plate comprises corrugation in the distribution area at both ends and corrugation in the heat transfer area in the middle. After the plates are overlapped, cold medium and hot medium flow toward the reverse directions in respective flow passage. The utility model has the advantages that the corrugated plate solves the matching problem between the pressure drop and heat transfer efficiency of the plate reasonably, has good medium self-uniform-distribution performance, and solves the problem of medium distribution and heat transfer reasonably.
Description
Technical field
The utility model relates to a kind of corrugated board structure that is used for full welded plate formula heat exchanger and lamella heat exchanger.
Background technology
At present, welded plate type heat exchanger is a kind of advanced person's in the world a heat exchanger structure form, with plate type heat exchanging element, and replaces the rubber cushion sealing of common plate type heat exchanger in the welded seal mode, has increased substantially the serviceability temperature and the bearing capacity of plate type heat exchanger.
Full welded plate formula heat exchanger corrugated cardboard sheet in the prior art, general single soft wave or the single hard ripple of adopting can not finely be taken into account pressure drop and heat transfer efficiency, and for the side direction charging, medium is prone to dry plate (dead band that medium is not flowed through) from uniform poor-performing.
Summary of the invention
The purpose of this utility model provides a kind of corrugated cardboard sheet, to solve the plate pressure drop and the heat transfer efficiency matching problem of welded plate shell heat exchanger.
The purpose of this utility model is achieved in that
Plate is a rectangular sheet, and the ripple on the described plate is made up of with middle heat transfer zone ripple the distributed area ripple at two ends, and described heat transfer zone ripple adopts to have along lambdoid ripple struction.
The angle that is positioned at the suitable herringbone ripple of middle heat transfer zone on the described plate is the 50-80 degree.
Described plate groups poststack, cold and hot medium flow direction in runner separately is opposite.
Described plate groups poststack, medium is passed in and out by two ends, and the opposite side medium is passed in and out by side direction.
The utlity model has following advantage:
1. plate pressure drop and heat transfer efficiency matching problem have rationally been solved;
2. medium is good from uniform property, has rationally solved dielectric distribution and heat transfer problem.
Description of drawings
Fig. 1 is a plate ripple struction schematic diagram of the present utility model.
Fig. 2 is a plate ripple angle schematic diagram of the present utility model.
Fig. 3 is the folded schematic diagram that concerns of plate groups of the present utility model.
The specific embodiment
Plate described in the utility model and ripple struction are referring to Fig. 1, on plate, be divided into diversion section and middle heat transfer segment that two ends distribute, with pressure drop of reasonable solution plate and heat transfer efficiency matching problem, when having good heat transfer property, has good fluid from uniform performance.On above-mentioned water conservancy diversion district and heat transfer zone, be furnished with ripple 1,2 respectively.Plate is shaped as rectangle, is furnished with the structure that adopts along herringbone ripple 2 on the heat transfer zone, and the ripple 1 that is furnished with in the water conservancy diversion district is referring to Fig. 1.The plate media of both sides is pure adverse current.The angle of the heat transfer zone ripple 2 in the middle of being positioned at is the best with 65 degree, referring to Fig. 2 in 50-80 degree scope.Technique scheme has rationally solved plate pressure drop and heat transfer efficiency matching problem.
The plate groups poststack, the distributed area corrugated surface of adjacent plate contacts, and the heat transfer zone ripple of adjacent plate contacts.Plate groups poststack, the two ends of plate are as the turnover distributed area of medium, and a side medium 4 is by the two ends turnover, and the centre of plate is as the heat transfer zone of medium, and opposite side medium 3 is passed in and out by side direction.Plate groups is folded can be referring to mode shown in Figure 3.
Claims (4)
