Technical Field
The utility model relates to the field of plate heat exchangers, in particular to a plate structure of a plate heat exchanger, which has small pressure drop, uniform medium distribution and high heat exchange efficiency.
Background
The plate heat exchanger is a detachable heat exchange device which is formed by compressing a plurality of corrugated heat transfer plates and rubber gaskets together at certain intervals. The plate is an important heat transfer element of the plate heat exchanger, a plurality of angular holes are formed on the plate to form a fluid distribution pipe and a fluid discharge pipe, two heat exchange media respectively flow into respective flow channels and flow guide areas and corrugated areas on the plate to form countercurrent or cocurrent flow to exchange heat through each plate.
In the prior art, a medium flows between the plates through the corner holes, forms turbulence through the concave-convex structure of the plates, and simultaneously generates pressure loss. The medium passes through the inlet corner hole, the inlet end flow guide area, the heat exchange area, the outlet end flow guide area and the outlet corner hole, and finally exchanges heat to finish flowing out of the equipment body. When the medium flowed in by the left side, when the left side flowed out, because the right side route is longer than the left side, the resistance is higher, easily forms the heat transfer blind spot, because the right side velocity of flow is lower simultaneously, the phenomenon such as scale deposit jam appears in the slab changeing. The same applies when the medium flows in from the right side and flows out from the right side.
Therefore, a novel plate is needed, the heat exchange dead zone can be reduced, and the heat exchange efficiency is improved.

Detailed Description
The utility model aims to overcome the defects of the prior art and manufacture a plate structure of a plate heat exchanger with small pressure drop, uniform medium distribution and high heat exchange efficiency. The problems of large pressure drop, uneven medium distribution and flowing dead zones of the plates of the conventional plate heat exchanger are solved.
The present application will now be described in detail with reference to the accompanying drawings:
as shown in fig. 1, the prior art plate mainly includes circular corner holes 2 for medium to enter and exit, a flow guiding area 3 for evenly distributing the medium, and a heat exchanging area 4 for most of the heat transferring function, and the rest of the structure is not described in detail since it is not in the scope of the patent claims.
As shown in fig. 2, the medium of the medium flow distribution diagram among the plates in the prior art flows through the inlet corner holes 2, the inlet end flow guide areas 3, the heat exchange areas 4, the outlet end flow guide areas 3 and the outlet corner holes 2, and finally, the heat exchange is completed and flows out of the equipment body. When the medium flowed in by the left side, left side outflow, because the right side route is longer than the left side, the resistance is higher, easily forms heat transfer blind spot 5, because the right side velocity of flow is lower simultaneously, the phenomenon such as scale deposit jam appears in the slab is changeing. The same applies when the medium flows in from the right side and flows out from the right side.
As shown in fig. 3, the plate for a plate heat exchanger with high heat exchange efficiency includes a plate body 1, an angular hole 2, a flow guiding area 3 and a heat exchange area 4 are arranged on the plate body 1, the angular hole 2 is a long hole along the transverse direction of the plate, and the angular hole is composed of two sections of circular arcs 21 and a connecting line 22 between the two sections of circular arcs 21. The connecting line 22 between the two arcs of the corner hole is a straight line or an arc line. The straight line connecting line between the two arcs 21 is tangent to the two arcs. One end of the angle hole close to the longitudinal center line of the plate main body inclines outwards. The circle center connecting line of the two arcs of the angle hole and the transverse center line of the plate main body form an included angle alpha which is 0-45 degrees. The long angle holes can uniformly distribute the medium to the flow guide area, and then the medium is uniformly distributed to the heat exchange area for heat exchange.
In contrast to the two types of panel corner holes shown in fig. 4, the panel corner holes of the present application extend in the direction of the panel length centerline on the basis of the prior art corner holes and are disposed at an angle α, typically between 0 ° and 45 °, to the panel transverse centerline. In the prior art, a medium flows between the plates through the corner holes, forms turbulence through the concave-convex structure of the plates, and simultaneously generates pressure loss. The enlarged part of the angle hole is shown in a shadow in the figure, and after the angle hole is enlarged, the flowing area of a medium in a non-heat exchange area between the plates is reduced, and the pressure loss of the medium is reduced.
As shown in FIG. 5, the flow distribution diagram of the medium between the plates of the present application, because the angular holes extend towards the length center line direction of the plates, the angular holes on one side are closer to the other side of the plates, and the path of the medium flowing towards the opposite side is shortened, compared with the prior art, the flow distribution diagram is more beneficial to the even distribution of the medium in the flow guide area, and the condition of heat exchange dead zones is improved. Meanwhile, due to the reduction of heat exchange dead zones, the effective heat exchange area of the plate is increased, and therefore the heat exchange efficiency of the plate is improved.
