Description
Technical Field
The utility model relates to a plate heat exchanger especially relates to a plate heat exchanger slab of honeycomb.
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, the left and right flow velocities of the heat transfer plate are uneven after the fluid enters the heat exchange area, and the heat transfer plate cannot complete sufficient heat exchange.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a honeycomb's plate heat exchanger slab, the water conservancy diversion district makes the fluid distribution more even, and the heat transfer district makes the fluid torrent more violent, improves to synthesize heat transfer ability more than 15%.
In order to achieve the above object, the utility model adopts the following technical scheme:
a plate type heat exchanger plate with a honeycomb structure comprises an angular hole, a flow guide area and a heat exchange area, wherein a concave-convex corrugated structure is arranged in the heat exchange area, reinforcing ribs are uniformly arranged in the heat exchange area, the reinforcing ribs are longitudinally arranged along the plate, and the reinforcing ribs and the concave-convex corrugated structure form a regular hexagonal honeycomb structure; the flow guide area is divided into 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 corner hole, and the other end of the streamline-shaped flow guide area is connected with the heat exchange area.
Positioning pits are arranged on two sides of the plate sheet and are arranged on two sides of the heat exchange area.
The number of the positioning pits is four, and the positioning pits are symmetrically arranged on two sides of the plate.
And a flow guide line is also arranged between the flow guide area and the heat exchange area, one part of the flow guide line is a long and short alternating flow guide line, the other part of the flow guide line is a short flow guide line, the long and short alternating flow guide line area is connected with the latticed flow guide area, and the short flow guide line area is connected with the streamlined flow guide area.
Compared with the prior art, the beneficial effects of the utility model are that:
1) 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, makes the fluid flow into heat transfer district at the more even distribution of water conservancy diversion in-process.
2) The heat exchange area is provided with a honeycomb-structure-shaped ripple, so that fluid is disturbed in narrow and tortuous channels among the plates, the fluid turbulence is more violent, the Reynolds number is improved, and the heat exchange capacity is enhanced.
3) The reinforcing ribs uniformly arranged in the heat exchange area are formed by pressing through the die pressing mould, so that the overall strength of the heat exchange plate is increased, the stretching and thinning amount of peripheral corrugations is reduced by 2% -3%, and the service life of the overall heat exchange plate is prolonged.
4) The slab location nest is 4, sets up in heat transfer district both sides, compares in traditional four corners location and has reduced the location interval, and is more firm when making the slab mutually support.
