Abstract

The invention discloses a structure for relieving corrugated stress concentration of a titanium heat exchange plate. The structure is arranged in the middle of the heat exchange plate. The heat exchange plate is a concavo-convex board surface component and consists of a hanging port, an entering and exiting port, a diversion area, a side rib and corrugations. The corrugations positioned on the board surface are longitudinally arranged in corrugated shape, and transverse adjacent corrugations are arranged in herringbone. The corrugations longitudinally arranged in a line on the board surface are alternately arranged according to an arc-shaped groove and a trapezoidal convex groove, the neighboring distances of the grooves are equal, and the heights are level. Through the technical improvements, corrugated bending angles are obviously reduced, and specifically speaking, angle bends are avoided to be arranged on a titanium plate by using an arc natural transition characteristic, so the stress concentration is greatly relieved to ensure that cracks are not generated during corrugation press forming of the titanium heat exchange plate, board surface cracking is less likely to be generated, and the solution of the problem significantly reduces the rejection rate and then the production cost is saved. On the other hand, the corrugated flow resistance of the arc-shaped groove structure is low, which is favorable for heat exchange medium flow and the improvement of heat exchange efficiency.

Description

Titanium matter heat exchanger plates ripple stress is concentrated and is extenuated structure

Technical field

The present invention relates to a kind of heat exchanger plates ripple struction design, specifically, the present invention relates to the concentrated structure of extenuating of a kind of titanium matter heat exchanger plates ripple stress.

Background technology

Heat exchanger plates is the main body heat exchange component of plate type heat exchanger, and the heat exchanger plates of processing with sheet metal is usually by certain regularly arranged ripple.The concavo-convex ripple of press forming removes and effectively improves the heat exchanger plates heat exchange area, also significantly increases plate face rigidity, also utilizes the guide effect of ripple to facilitate heat exchanging medium flow formation turbulent flow between the heat exchanger plates simultaneously, and turbulent flow helps promoting the heat exchange efficiency of heat transferring medium.At present, the heat exchanger plates on the market in the commodity plate type heat exchanger all is pressed with concavo-convex alternate trapezoidal ripple, the bellows-shaped rule of this structure, and press forming is easy, and the heat transferring medium trickling is smooth and easy, can reach the heat exchange efficiency of target.But concavo-convex alternate trapezoidal moire angles is curved many, and there is big problem of stress concentration in the crook, angle.The good toughness of general steel plate can digest crook, angle stress, can not produce plate facial cleft line or cracking problem.When heat transferring medium was stronger seawater of corrosivity or bittern, the material of heat exchanger plates was then selected the titanium scutum for use.Titanium scutum corrosion resistant ability is fine, but toughness is more weaker than general steel plate, on the plate face, is prone to crack in the crook, angle during corrugating, even produces cracking.This problem restricts the workmanship of titanium matter heat exchanger plates always.Be on the other hand titanium plate price than ordinary steel plate hight more than ten times, high scrappage must increase production cost.

Summary of the invention

The present invention is primarily aimed at the problem that existing heat exchanger plates ripple struction is not suitable for titanium matter heat exchanger plates; The concentrated structure of extenuating of a kind of titanium matter heat exchanger plates ripple stress is proposed; This is simple and reasonable for structure, and the angle is curved extenuates problem of stress concentration through reducing, and crackle or cracking quality problems do not take place during corrugating.

The present invention realizes technical goal through following technical proposals.

Titanium matter heat exchanger plates ripple stress is concentrated and is extenuated structure, and this structure is located at the heat exchanger plates middle part.Said heat exchanger plates is the buckplate surface member, and it is made up of mouth hanging, import and export, water conservancy diversion district, limit rib and ripple.Said ripple is positioned at plate face middle part, vertically is corrugated and arranges, and laterally adjacent corrugations is by circular array; Its improvements are: the ripple of vertical in-line arrangement row is pressed circular groove and the alternately arrangement of trapezoidal tongue on the plate face.

Spacing equates both level between circular groove in the said structure and the adjacent trapezoidal tongue.

The present invention compared with prior art has following good effect:

1, circular groove does not have the angle curved, and titanium plate nature transition bending does not produce problem of stress concentration during compacting, and quality problems can not crack or ftracture;

2, circular groove is shaped gradually, and the compacting steady quality significantly reduces manufacturing cost;

3, the circular groove flow resistance is little, helps heat transferring medium and flows, and promotes heat exchange efficiency.

Fig. 1 is a heat exchanger plates overall structure sketch map.

Fig. 2 is the structural representation in vertical moire of the present invention cross section.

Fig. 3 is the structure contrast sketch map in prior art vertical moire cross section.

The specific embodiment

According to accompanying drawing the present invention is described further below.

Titanium matter heat exchanger plates ripple stress shown in Figure 1 is concentrated and is extenuated structure, and this structure is located at the heat exchanger plates middle part.Said heat exchanger plates is the buckplate surface member, and it is made up of mouth hanging 1, import and export 2, water conservancy diversion district 3, limit rib 4 and ripple 5.The ripple 5 that is positioned on the central panel face vertically is the corrugated arrangement, and laterally adjacent corrugations 5 is by circular array.Technological improvement of the present invention is that the ripple 5 of vertical in-line arrangement row on the plate face is alternately arranged by circular groove 5.1 and trapezoidal tongue 5.2, and both replace arrangement pitches and equate level.Significantly reduce ripple 5 bending angles through above-mentioned technological improvement; Be to utilize circular arc nature transient characteristic to avoid titanium plate angle curved specifically; Do not have the curved stress of extenuating greatly in angle to concentrate, make titanium matter heat exchanger plates ripple 5 press formings not crack, more can not produce plate face cracking; The solution of this problem significantly reduces scrappage, thereby saves production cost.Ripple 5 flow resistances that are the circular groove structure on the other hand are little, help heat transferring medium and flow, and promote heat exchange efficiency.
