It is connected with the first flanging 33, the 3rd connection flanging 5 is connected with the second flanging 34, heat exchanger plates are stacked to constitute closed at both ends, another two ends
The medium runner of insertion；
Heat exchanger plates 1 of the present invention can be quadrangle, and the transverse width in lateral connection portion 2 is 2~35mm, less than this
During value, the intensity in lateral connection portion 2 is smaller, and difficult forming, if more than this scope, the rigidity in lateral connection portion 2 is deteriorated, born
Deformation tendency becomes big after larger medium differential pressure, specifically, for the heat exchanger plates 1 of 150 × 150mm specifications, lateral connection portion 2
Width can be 10mm or so：For the heat exchanger plates 1 of 1000 × 1000mm specifications, the width in lateral connection portion 2 can be 30mm
Left and right, the height of the first connection flanging 3 is 5~20mm, if the height of the first connection flanging 3 is smaller, between causing between plate
Gap is too small, easily causes blockage problem, if the excessive height of the first connection flanging 3, shaping is difficult to, and shaping precision compared with
It is low, specifically, for the heat exchanger plates 1 of 150 × 150mm specifications, the height of the first connection flanging 3 can be 4mm or so, for
The heat exchanger plates 1 of 1000 × 1000mm specifications, the height of the first connection flanging 3 can be 5mm or so.
First flanging 33 is identical with the forming direction of the second connection flanging 4, one end and the end of the second connection flanging 4
Be connected, the end of its other end and the first connection flanging 3 intersects at the edge in lateral connection portion 2, the second connection flanging 4 with
The equal length of first flanging 33, the second flanging 34 is identical with the overbending direction of the 3rd connection flanging 5, and one end connects with the 3rd
The end for connecing flanging 5 is connected, and the end of its other end and the first connection flanging 3 intersects at the edge in lateral connection portion 2, the
Two flangings 34 are identical with the height of the 3rd connection flanging 5, and the length of the first connection flanging 3 connects with the second connection flanging 4 and the 3rd
The height sum for connecing flanging 5 is equal；Specifically, the edge that the second connection flanging 4 is heat exchanger plates 1 is vertically folded upward at
Formed, and be connected with the first flanging 33, and the height after both bendings is identical；Second flanging 34 is curved with the 3rd connection flanging 5
Folding direction is identical, and one end is connected with the end of the 3rd connection flanging 5, its other end and the end of the first connection flanging 3
The edge in lateral connection portion 2 is intersected at, the second flanging 34 is identical with the height of the 3rd connection flanging 5, specifically, the 3rd connection
Flanging 5 is that the other edge of heat exchanger plates 1 is bent to form vertically downwards, and is connected with the second flanging 34, and both bendings
Height afterwards is identical；
As shown in Figure 3,4, the first flanging 33 is connected with the second connection flanging 4 by transition part 15, the second flanging 34 and
Three connection flangings 5 are connected by transition part 15, further, and transition part 15 is arc-shaped or hypotenuse；This structure induction medium exists
During into main heat exchange area 6, while into lateral connection portion 2, it is to avoid be located at flow dead in the lateral connection portion 2 of corner
Presence, while arc transition form reduces the harm of transition part stress concentration.
As shown in Figure 1,3, parallel in main heat exchange area to be provided with some first convex ridges 61, the edge of heat exchanger plates 1 limits side
It is parallel in angle guiding region 7, corner guiding region 7 to be provided with the second convex ridge 71, the bearing of trend of first convex ridge 61 and the one of heat exchanger plates 1
Diagonal is parallel, and the bearing of trend of the second convex ridge 71 and the first convex ridge 61 is at an angle, the height of the first convex ridge 61 and the
The height of two convex ridges 71 is identical, and equal to the height of the first connection flanging 3；The second convex ridge 71 set on corner guiding region 7 has
There is water conservancy diversion, in the presence of corner guiding region 7, the fluid of diverse location is entered main heat exchange area 6 with flow velocity evenly
It is interior, the harm of plate local scaling or corrosion caused by fluid velocity local velocity is too low or too high is reduced, is improved simultaneously
Angle between the bearing of trend of the formed precision of heat exchanger plates, the first convex ridge 61 and the second convex ridge 71 is 30~150 °, such as 30 °,
40 °, 45 °, 50 °, 60 °, 90 °, 100 °, 120 °, 150 °, as shown in fig. 6, the bearing of trend of the first convex ridge 61 and the second convex ridge 71
