Description
Technical field
The present invention relates to HVAC, automobile, refrigeration and transport field, more particularly to a kind of plate type heat exchanger and it is used for
The heat exchanger plates of plate type heat exchanger.
Background technology
Plate type heat exchanger be formed by a series of metal heat-exchange plate closed assemblies with certain bellows-shaped it is a kind of new
High-performance heat exchanger.Thin rectangular shape passage is formed between each heat exchange plate, heat exchange is carried out by heat exchange plate, its function is by one
The heat transfer of kind fluid is to one other fluid.
At present, the bellows-shaped of the corrugated plating of most of plate type heat exchanger or heat exchanger plates is in " people " font, i.e., at one piece not
Stamp out continuously arranged " people " font wavy channel structure (forming corrugated plating) on rust steel sheet, then upper and lower two pieces of ripples
Plate reversely overlaps, and forms some not connected fluid passages.When in use, cold fluid and heat are passed through in different passages
Fluid, so as to realize heat exchange purpose.
In order to improve the efficiency of heat transfer, make every effort to accomplish two kinds of fluids across heat exchanger plates can fully heat-shift, institute
With the whether rational in infrastructure most important of heat exchanger plates.
Through analysis and research, existing " people " font corrugated plating, as shown in figure 1, being mostly symmetrically structure, in corrugated plating
On width, the crest portion of herringbone wavy channel structure and the width in trough portion are constant.On the section of passage, knot
Structure and porosity are completely the same, and its coefficient of partial resistance is close to equal.In the linearity region of import, outlet, flow distance is most short,
It is minimum to flow drag overall, flow velocity is maximum；Deviateing import, exporting more remote region, flow distance is longer, and flowing drag overall is got over
Greatly, flow velocity is lower.For fluid on whole flow area, velocity flow profile is uneven, and a large amount of fluids are flowed out by shortest path, entered in distance
Mouth, export compared with far region, flow into and participate in exchange heat without enough fluids, for wide plate, unilateral adverse current plate heat exchanger, cold,
Hot fluid main flow area is not overlapping or overlapping deficiency, heat exchange area do not make full use of, and causes total heat exchange efficiency low.
Existing herringbone corrugated plating can strengthen turbulent flow, with by being arranged to asthenic sheet structure, to a certain degree
On, the problem of alleviating inner fluid passage skewness.But for the herringbone corrugated plating with wider width, no
The problem of fluid distrbution inequality can be inherently eliminated, and strengthen turbulent flow and asthenic sheet structure by application and using empty
Between limitation.
In view of this, it is necessory to provide the heat exchanger plates structure design of optimization a kind of, to improve always changing for plate type heat exchanger
The thermal efficiency.
The content of the invention
It is an object of the invention to solve at least in part in the structure of above-mentioned existing herringbone corrugated plating or heat exchanger plates
Deficiency, eliminate heat exchanger plates on inner fluid passage skewness, so as to improve total heat exchange efficiency of plate type heat exchanger.
It is another object of the present invention to provide a kind of new heat exchanger plates or heat exchanger for plate type heat exchanger, with
At least one of following effects are realized at least in part：
On the width of heat exchanger plates so that the even width consecutive variations in crest portion and trough portion, that is, increase or subtract
It is small；Cause porosity consecutive variations on the section of passage and in structure；In the direction of the width, its coefficient of partial resistance uniformly becomes
Change；In the linearity region of import, outlet, larger coefficient of partial resistance is designed, apart from import, outlet region farther out, if
Count less coefficient of partial resistance；In whole runner, the flowing drag overall in each region is close to equal；In whole flow area
On, flow velocity is close to equal.
According to an aspect of the invention, there is provided a kind of heat exchanger plates for plate type heat exchanger, set on the heat exchanger plates
