Abstract

The invention discloses a full welded plate bundle with reinforced structures. A plurality of plate tubes and reinforcement plates form a heat exchange plate bundle with a corrugated area. The plate bundle is characterized in that: horizontal straight sides and vertical straight sides of the heat exchange plate bundle, namely inlet and outlet end parts of the plate bundle and lateral inlet and outlet end parts of the plate bundle are provided with reinforced structures that the reinforcement plates with through-flow holes form plate straight sides; and the reinforcement plates and the plate straight sides are fixed in a welding or non-welding mode. The full welded plate bundle can solve the technical problems that the loading capacity of inlet and outlet straight-side plates of the plate bundle and the integral rigidity of the plate bundle can be reinforced and fluid distribution uniformity of a medium at inlets and outlets can be strengthened under the condition of meeting the requirement of pressure drop of a heat exchanger.

Description

A kind of full welded plate bundle with reinforcement structure
Technical field
The invention belongs to technical field of heat exchangers, relate to the improving technology that a kind of import and export place plate straight flange that is used for welded plate type heat exchanger plate bundle is strengthened structure.
Background technology
Welded plate type heat exchanger is as a kind of high-performance heat exchanger, has heat transfer efficiency height, high temperature resistant, advantage that bearing capacity is strong, is a kind of heat-transfer equipment of high speed development in recent years.
Adopt between the plate of welded plate type heat exchanger and be welded to connect, in order to guarantee welding, in the periphery straight flange structures that adopt of plate, the straight flange zone of plate is with respect to the ripple area of plate more, its bearing capacity reduces greatly, becomes the major hidden danger that welded plate type heat exchanger lost efficacy.The peripheral straight flange of plate is as medium import and export passage simultaneously, how under the condition that satisfies the heat exchanger pressure drop, can stiffener bundle import and export straight flange plate bearing capacity and plate bundle integral rigidity, even fluid distribution that again can the amplified medium import and export becomes a difficult problem in welded plate type heat exchanger field.
Summary of the invention
The purpose of this invention is to provide a kind of full welded plate formula heat exchanger of strengthening structure that has, to solve under the condition that satisfies the heat exchanger pressure drop, can stiffener bundle import and export straight flange plate bearing capacity and plate bundle integral rigidity, the technical problem of even fluid distribution that again can the amplified medium import and export.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is, constitute heat exchanger plates bundle by some plate pipes and stiffener with corrugated regions, it is characterized in that, described plate pipe is directly by forming behind two plate make-ups, the horizontal straight flange of described heat exchanger plates bundle, vertical straight flange, just plate bundle import and export end and plate bundle side direction import and export end, the stiffener that is provided with through flow hole is formed the reinforcement structure of plate straight flange; Described stiffener and plate straight flange adopt the mode of welding or non-welding to fix.
Aforesaid a kind of full welded plate formula heat exchanger of strengthening structure that has, stiffener fixing on each side straight flange is made of some strip stiffeners, the import and export position between the corresponding two boards sheet of each strip stiffener or the import and export position of corresponding polylith plate, and the some through flow holes on the stiffener are corresponding with each wavy channel.
As above-mentioned a kind of full welded plate formula heat exchanger with reinforcement structure, the through flow hole shape on the described stiffener is circle, ellipse or Long Circle.
The present invention adopts the strip stiffener that has through flow hole effectively to be connected with plate, satisfy under the condition of all welded type heat exchanger pressure drop requirement, plate bundle import and export place's plate bearing capacity and plate bundle integral rigidity had both been strengthened, increased the fluid split distribution performance at plate bundle import and export place again, be particularly suitable for welded plate type heat exchanger and use.

The specific embodiment
Technical scheme of the present invention is consulted accompanying drawing.The reinforcement structure that is used for the plate straight flange of welded plate type heat exchanger medium import and export is based on the structure of the heat exchanger plates bundle with plate corrugated regions 1 that constitutes behind two boards sheet shown in Fig. 1,2 or the polylith plate make-up, other reinforcement need be set between plate.Be provided with the stiffener 4 of through flow hole 5 at plate bundle import and export end (the horizontal straight flange of plate) 3 and plate bundle side direction import and export position (the vertical straight flange of plate) 2 respectively and form.The fixed structure form of described stiffener is referring to Fig. 3.Stiffener and plate straight flange adopt the mode of welding or non-welding to fix.Described stiffener is a strip stiffener as shown in Figure 4.Each strip stiffener, be arranged in order fixing, wavy channel between the corresponding every two boards sheet of difference, and correspondence has through flow hole 5 on the stiffener at each wavy channel place, specifically can be referring to the stiffener partial structurtes of the reinforcement structure shown in Fig. 5 and the structure cutaway sectional view of the reinforcement plate shown in Fig. 5.
What the stiffener in the foregoing description adopted is circular through flow hole 5 structures.In addition, through flow hole 5 can also adopt ellipse, Long Circle, rectangle or other shape.
Plate journey fluid of the present invention evenly flows into the plate bundle by plate bundle end stiffener through flow hole, shell-side fluid evenly flows into the plate bundle by plate bundle side direction stiffener opening, plate, shell-side fluid flow out by opposite side stiffener through flow hole respectively after by heat exchange, when making welded plate type heat exchanger under high temperature, high pressure, satisfy to fall requirement, both strengthen plate bundle import and export place's plate bearing capacity and plate bundle integral rigidity, increased the fluid cloth performance at plate bundle import and export place again.
