Description
Technical field
The utility model relates to plate type heat exchanger and manufactures field, is specially a kind of plate type heat exchanger with Novel sheet bar and distributor.
Background technology
Plate type heat exchanger can play its advantage under the operating mode of single-phase heat exchange, but in two-phase heat-exchanging state, because the difference such as physical property, fluidised form of gas-liquid two-phase fluid is larger, be difficult to realize fluid well-distributing distribute and uniform flow flowing in runner between plate, when especially gas-liquid two-phase mix refrigerant is sprayed by distributor apertures the liquid refrigerant of high pressure, abundant atomization cannot be realized, thus affect the quick volatilization of liquid refrigerant, and then increase flow resistance, reduce the heat exchange property of heat exchanger.In addition in the runner of the equally distributed plate composition of ripple, the assignment of traffic of fluid is uneven, comparatively large, more less away from its flow velocity of this region to the flow velocity of the straight line near zone of outlet from import, in runner, the uneven meeting of assignment of traffic causes flow resistance to increase and the reduction of heat exchanger heat exchange property.After gas-liquid two-phase mix refrigerant enters distributor, fully cannot be mixed, thus make flow resistance comparatively large, flow can not effectively uniform distribution and between plate Uniform Flow in runner, thus make that heat exchanger pressure drop is comparatively large, heat exchange property reduction.Therefore, require further improvement the structure of plate-type heat exchanger slab and distributor, to obtain best heat exchange property.
Utility model content
For the problems referred to above, the utility model provides one and is provided with Novel plate heat exchanger.
The technical solution adopted in the utility model is, build a kind of Novel plate heat exchanger, above-mentioned plate type heat exchanger is provided with corrugated plate group, above-mentioned corrugated plate group comprises first wave card and the Second Wave card of the stacked setting in interval, a corner apertures of first wave card is other is provided with the first distributor, and the sidewall of a corner apertures of Second Wave card is provided with the second distributor; The medium that above-mentioned first distributor of multiple coaxial setting and the second distributor form plate type heat exchanger distributes passage.Above-mentioned first distributor comprises fin and outer fin in annular, and the height of above-mentioned outer fin, higher than the height of interior fin, forms fluid cavity between above-mentioned interior fin and outer fin; Above-mentioned second distributor comprises two the axial dispensing orifices be connected with Second Wave card corner apertures, is also provided with arc distribution plate between above-mentioned dispensing orifice.
Further, above-mentioned outer fin is also provided with many medium dispersion slots, the bottom land of above-mentioned distribution dispersion slot lower than the peak of above-mentioned interior fin, higher than the minimum point of above-mentioned fluid cavity.While being conducive to reducing flow resistance, force fluid to start flowing along the plate ripple away from fluid distributor opposite side, make flow distribution of fluid between plate more even, improve plate heat exchanger effectiveness.
Further, the cross section of above-mentioned dispersion slot is circular arc or ellipse arc.
Further, above-mentioned multiple dispersion slot helically centrifugal type distribution or radial type distribution around corner apertures center.Force fluid to start flowing along the plate ripple away from fluid distributor opposite side, make flow distribution of fluid between plate more even, improve plate heat exchanger effectiveness.
Further, the side of above-mentioned second distributor is other is provided with annular heavy stand face, and the upper surface of above-mentioned annular heavy stand face and above-mentioned Second Wave card forms cylindrical cavity.Be mainly used in abundant mixing.
Further, above-mentioned first wave card and Second Wave card are equipped with boss and the pit of multiple positions form fit.For the screens clamping when assembling, make whole corrugated plate group firm stable more.
Further, above-mentioned interior fin is also provided with many gathering sills.For direct fluid and reduction flow resistance.
Compared with prior art, a kind of Novel plate heat exchanger provided by the utility model, by improving sheet structure and dispensing arrangement, while further increasing the heat exchanger effectiveness of plate type heat exchanger, also have fluid chemical field abundant, fluid flowing is even, the advantage that flow resistance is low.
