Abstract
The utility model relates to a plate structure of plate heat exchanger, including angular hole, water conservancy diversion district, heat transfer district, the water conservancy diversion district is latticed water conservancy diversion district and streamlined water conservancy diversion district two parts, streamlined water conservancy diversion district is on the upper portion of latticed water conservancy diversion district, and the one end and an angular hole of streamlined water conservancy diversion district are linked together, and the other end and the heat transfer district of streamlined water conservancy diversion district are linked together. Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses set up the two parts of different resistances at water conservancy diversion district and water conservancy diversion line, because the fluid flows in by a side angle hole always, the event will keep away from the regional establishment of fluid import and export one side to the low resistance district, can make the fluid flow in heat transfer district at the more even distribution of water conservancy diversion in-process, improve the comprehensive heat transfer ability of slab.
Description
Technical Field
The utility model relates to a plate heat exchanger especially relates to a plate structure of plate heat exchanger.
Background
The heat transfer plate of the prior plate heat exchanger is provided with an angle hole, a flow guide area, a heat exchange area and a sealing groove, wherein the flow guide area is generally designed in a triangular shape, the heat exchange area is generally designed in a symmetrical corrugated shape, fluid flows in from the angle hole at one side, enters the heat exchange area through the flow guide area, and flows out of the angle hole through the flow guide area at the other side after heat exchange. Because the fluid always flows in from a side corner hole, the fluid is always unevenly distributed in the triangular diversion area, and left and right flow velocities of the heat transfer plate are uneven after the fluid enters the heat exchange area, so that the heat transfer plate cannot complete sufficient heat exchange.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plate structure of plate heat exchanger, the water conservancy diversion district makes the fluid distribution more even, effectively improves the comprehensive heat transfer ability of slab.
In order to achieve the above object, the utility model adopts the following technical scheme:
a plate structure of a plate heat exchanger comprises angle holes, a flow guide area and a heat exchange area, wherein the flow guide area is composed of a grid-shaped flow guide area and a streamline-shaped flow guide area, the streamline-shaped flow guide area is arranged on the upper portion of the grid-shaped flow guide area, one end of the streamline-shaped flow guide area is connected with one angle hole, and the other end of the streamline-shaped flow guide area is connected with the heat exchange area.
And flow guide lines are also arranged between the flow guide area and the heat exchange area, one part of the flow guide lines are long and short alternate flow guide lines, the other part of the flow guide lines are all short flow guide lines, the long and short alternate flow guide line areas are bordered by the latticed flow guide area, and the short flow guide line areas are bordered by the streamlined flow guide area.
The number of the corner holes is 4.
The diversion area is triangular.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses set up the two parts of different resistances at water conservancy diversion district and water conservancy diversion line, because the fluid flows in by a side angle hole always, the event will keep away from the regional establishment of fluid import and export one side to the low resistance district, can make the fluid flow in heat transfer district at the more even distribution of water conservancy diversion in-process, improve the comprehensive heat transfer ability of slab.
