Abstract
The invention discloses a plate heat exchanger sheet with dimple-shaped pits. The plate heat exchanger sheet with the dimple-shaped pits comprises a medium inlet, an inlet flow-guiding area, an outlet flow-guiding area, an inlet flow-dividing area, an outlet flow-dividing area, a heat-exchanging area, a medium outlet and positioning holes. The positioning holes are formed in the middle portions of two ends of the plate heat exchanger sheet. The medium inlet is formed in one end, adjacent to the positioning hole, of the plate heat exchanger sheet. The medium inlet is connected with the inlet flow-guiding area and the inlet flow-dividing area. The medium outlet is formed in the other end, adjacent to the positioning hole, of the plate heat exchanger sheet. The medium outlet is connected with the outlet flow-guiding area and the outlet flow-dividing area. The heat exchanging area is arranged on the middle portion of the plate heat exchanger sheet. The dimple-shaped pits are formed in the heat exchanging area. Due to the fact that the dimple-shaped pits are formed in a main heat exchanging area of a plate heat exchanger along wave crests and wave troughs of a corrugated flow direction, disturbance of fluid in a flow channel is improved, pressure loss of the fluid in the flow channel is reduced, comprehensive performance of the plate heat exchanger is optimized.
Description
Technical field
The present invention relates to a kind of heat exchanger plate, be specifically related to a kind of plate-type heat exchanger slab that adds the pit of dimple shape.
Background technology
Plate type heat exchanger compare with shell-and-tube heat exchanger have that heat transfer coefficient is high, logarithmic mean temperature difference (LMTD) is large, terminal temperature difference is little, floor space is little, lightweight, price is low, the advantage such as easy to make, easy cleaning, heat loss are little, less scaling.Plate-type heat exchanger slab is the most important parts of plate type heat exchanger, and the design of plate directly has influence on the heat transfer effect of whole plate type heat exchanger.
Plate-type heat exchanger slab is the critical piece that affects the plate type heat exchanger performance.At present, the bellows-shaped of the plate of plate type heat exchanger is numerous: herringbone ripple, straight ripple, the straight ripple of ladder type, indentation ripple etc.These plate heat transfer zone bellows-shaped are different, but are only all that the heat exchanging zone is carried out primary reinforcement and conducted heat.Therefore the secondary hardening heat transfer has been carried out in the present invention's research on the basis of original plate, from heat transfer effect and the pressure loss two aspects, plate is optimized.
Summary of the invention
Goal of the invention: the objective of the invention is provides the plate-type heat exchanger slab of the better pit that adds the dimple shape of a kind of heat transfer effect in order to solve the deficiencies in the prior art.
technical scheme: for achieving the above object, the invention provides a kind of plate-type heat exchanger slab that adds the pit of dimple shape, comprise the medium import, the import guiding region, the outlet guiding region, the import shunting zone, the outlet shunting zone, heat transfer zone, media outlet and locating hole, middle part, described plate two ends is provided with locating hole, plate one end is provided with the medium import adjacent with locating hole, the medium import is connected with the import shunting zone with the import guiding region, the plate other end is provided with the media outlet adjacent with locating hole, media outlet is connected with the outlet shunting zone with the outlet guiding region, the plate middle part is provided with heat transfer zone, described heat transfer zone has additional the pit of dimple shape.
As optimization, described heat transfer zone is ripple struction, heat transfer zone along ripple flow to crest and the trough place pit that has additional the dimple shape.
As optimization, described heat transfer zone along ripple flow to the crest place have additional the pit of dimple shape.
As optimization, described heat transfer zone along ripple flow to the trough place have additional the pit of dimple shape.
As optimization, the opening diameter of the pit of described dimple shape is 2mm-7mm, and the degree of depth is 0.2mm-1mm.
As optimization, the pit of the dimple shape at described heat transfer zone crest place is the pit of spill dimple shape, and the pit of the dimple shape at described trough place is the pit of convex dimple shape.
As optimization, described heat transfer zone ripple flow is to being shaped as ripple, herringbone ripple, straight ripple, the straight ripple of ladder type or indentation ripple a kind of shape wherein anyhow.
The pit that increases the dimple shape on tortuous ripple can be added in ripple flex point place and also can be added on bellows segment, and the angle that tortuous ripple is many also can increase the pit of dimple shape in the above.
beneficial effect: the plate-type heat exchanger slab that adds the pit of dimple shape of the present invention, by on the main flow heat transfer zone of plate type heat exchanger along ripple flow to crest and the trough place pit that has additional the dimple shape, plate type heat exchanger is carried out the secondary hardening heat exchange, can increase the heat exchange area of fluid, increase the disturbance of fluid in runner, thereby can increase the heat transfer effect of plate type heat exchanger, the pit of dimple shape can be used as and uses the flow resistance that is used for reducing fluid in hydrodynamics, thereby the pressure loss of fluid in runner reduced, optimized the combination property of plate type heat exchanger.
