Abstract
The utility model discloses a plate-type heat exchanger plate with additional dimple-like pits. The plate-type heat exchanger plate with additional dimple-like pits comprises a medium inlet, an inlet guide area, an outlet guide area, an inlet distribution area, an outlet distribution area, a heat exchange area, a medium outlet and positioning holes. The middle of each end of the plate is provided with one positioning hole. The medium outlet adjacent to one positioning hole is reserved at one end of the plate and is connected with the inlet guide area and the inlet distribution area. The medium outlet adjacent to the other positioning hole is reserved at the other end of the plate and is connected with the outlet guide area and the outlet distribution area. The heat exchange area is reserved in the middle of the plate. Additional dimple-like pits are reserved on the heat exchange area. The additional dimple-like pits are reserved at peaks and troughs on the main flow heat exchange area of the plate-type heat exchanger along corrugate flows, turbulence of fluid in channels is improved, and accordingly pressure loss of the fluid in the channels is reduced, and the comprehensive performances of the plate-type heat exchanger are optimized.
Description
Technical field
The utility model relates to a kind of heat exchanger plate, is specifically related to a kind of plate type heat exchanger plate that adds the pit of dimple shape.
Background technology
Plate type heat exchanger compare with shell-and-tube heat exchanger have the heat transfer coefficient height, logarithmic mean temperature difference (LMTD) is big, terminal temperature difference is little, floor space is little, in light weight, advantage such as price is low, easy to make, easy cleaning, heat loss are little, less scaling.The plate type heat exchanger plate is the most important parts of plate type heat exchanger, and the design of plate directly has influence on the heat exchange effect of whole plate type heat exchanger.
The plate type heat exchanger plate is the critical piece that influences 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 have nothing in common with each other, but all only are that the primary reinforcement heat transfer is carried out in the heat exchanging zone.Therefore the secondary augmentation of heat transfer has been carried out in the utility model research on the basis of original plate, from heat exchange effect and the pressure loss two aspects plate is optimized.
The utility model content
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, the plate type heat exchanger plate of the better pit that adds the dimple shape of a kind of heat exchange effect to be provided.
Technical scheme: for achieving the above object; The utility model provides a kind of plate type heat exchanger plate that adds the pit of dimple shape, comprises medium import, import water conservancy diversion district, outlet water conservancy diversion district, import shunting zone, outlet shunting zone, heat transfer zone, media outlet and locating hole, and middle part, said plate two ends is provided with locating hole; Plate one end is provided with the medium import adjacent with locating hole; The medium import links to each other with the import shunting zone with import water conservancy diversion district, and the plate other end is provided with the media outlet adjacent with locating hole, and media outlet links to each other with the outlet shunting zone with outlet water conservancy diversion district; The plate middle part is provided with heat transfer zone, and said heat transfer zone has additional the pit of dimple shape.
As optimization, said heat transfer zone is a ripple struction, heat transfer zone along ripple flow to crest and the trough place pit that has additional the dimple shape.
As optimization, said heat transfer zone along ripple flow to the crest place have additional the pit of dimple shape.
As optimization, said 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 said dimple shape is 2mm-7mm, and the degree of depth is 0.2mm-1mm.
As optimization, the pit of the dimple shape at said heat transfer zone crest place is the pit of spill dimple shape, and the pit of the dimple shape at said trough place is the pit of convex dimple shape.
As optimization, said 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 the tortuous ripple can be added in ripple flex point place and also can be added on the 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 plate of the pit that adds the dimple shape of the utility model; Through in the main flow heat transfer zone upper edge of plate type heat exchanger ripple flow to crest and the trough place pit that has additional the dimple shape; Plate type heat exchanger is carried out the secondary enhanced heat exchange, can increase the heat exchange area of fluid, increase the disturbance of fluid in runner; Thereby can increase the heat exchange effect of plate type heat exchanger; The pit of dimple shape can be used as use is used for reducing fluid in hydrodynamics flow resistance, thereby the pressure loss of fluid in runner reduced, and has optimized the combination property of plate type heat exchanger.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the longitudinal cross-section sketch map of the plate type heat exchanger plate of the utility model pit of adding the dimple shape.
The specific embodiment
Like a kind of plate type heat exchanger plate that adds the pit of dimple shape shown in the drawings; Comprise medium import 1, import water conservancy diversion district 2, outlet water conservancy diversion district 3, import shunting zone 4, outlet shunting zone 5, heat transfer zone 6, media outlet 7 and locating hole 8, middle part, said plate two ends is provided with locating hole 8, and plate one end is provided with the medium import 1 adjacent with locating hole 8; Medium import 1 links to each other with import shunting zone 4 with import water conservancy diversion district 2; The plate other end is provided with the media outlet 7 adjacent with locating hole 8, and media outlet 7 links to each other with outlet shunting zone 5 with outlet water conservancy diversion district 3, is provided with heat transfer zone 6 in the middle part of the plate; Said heat transfer zone 6 is a ripple struction; Heat transfer zone 6 along ripple flow to crest and the trough place pit 9 that has additional the dimple shape, the opening diameter of the pit 9 of said dimple shape is 2mm-7mm, the degree of depth is 0.2mm-1mm; The pit 9 of the dimple shape at said heat transfer zone 6 crest places is the pit 9 of spill dimple shape, and the pit 9 of the dimple shape at trough place is the pit 9 of convex dimple shape.
A kind of shape of said heat transfer zone 6 ripple flows in being shaped as ripple, herringbone ripple, straight ripple, the straight ripple of ladder type or indentation ripple anyhow, during the heat exchanger assembling, ° complete pressing of identical plate Rotate 180 gets final product.
