Embodiment 1

[0023] Embodiment 1, a herringbone corrugated plate with anchor points and the plate group composed of it.

[0024] refer to figure 1 , 2 According to the present invention, corrugated grooves for positioning points are arranged on the surface of the heat exchange area of ​​the herringbone corrugated plate 1. The positioning point 2 is a convex or concave corrugation relative to one side of the plate, and a concave or convex corrugation relative to the other side of the plate. The position of the positioning point can be set not only on the convex corrugation of the plate, but also on the concave corrugation. Since there can be both convex and concave positioning point corrugated grooves on one side of the plate, the positioning points are symmetrically distributed on both sides of the plate heat exchange area. This arrangement makes the herringbone corrugated plates aligned. A plate can be combined with the previous plate only by horizontally rotating 180°, so that the conv...

Embodiment 2

[0025] Embodiment 2, foam-shaped corrugated sheet with positioning points and the sheet group composed of it.

[0026] refer to Figure 3a , 3b , the number 3 in the figure is a raised corrugation, the number 4 is a concave corrugation, the number 21 is a raised positioning point, and the number 22 is a concave positioning point. The positioning point 2 can be set on the bubble corrugation, or it can be set on the flat plate between the bubble corrugations; similar to this kind of convex and concave bubble corrugated plates, when assembling, the latter plate needs to be vertical Or turn it horizontally 180° to pair with the previous plate, so that the raised corrugations of one plate are opposite to the raised corrugations of the adjacent plate, so when setting the positioning point, the side of the heat exchange area of ​​the plate If the positioning point is a convex (concave) corrugation, then the positioning point on the other side that is vertically or horizontally symm...

Abstract

The invention discloses a heat exchanger plate set positioning device. The device is provided with multiple rows of projected or recessed ripples in each plate heat exchange area; and after plates are assembled, the projected ripples of one plate are buckled with the recessed ripples of the adjacent plates to limit the moving dislocation of the adjacent plates so as to realize a positioning function of a heat exchanger plate set. The positioning device improves the plate assembly precision, effectively prevents the leakage problem of the plate set caused by dislocation between the adjacent plates under high-temperature or high-pressure and alternating load operation environment, and has the advantages of improvement of the pressure bearing capacity of the plate set and prolonging of the service life of the plate set.

Description

technical field [0001] The invention belongs to the design field of plate heat exchangers, in particular to a heat exchanger plate group positioning device. Background technique [0002] As a high-efficiency energy-saving equipment, plate heat exchangers have been widely used in petrochemical, aerospace, food, medicine, thermoelectric nuclear power and other industries. According to different connection methods, plate heat exchangers are mainly divided into detachable plate heat exchangers and fully welded plate heat exchangers. [0003] Auxiliary positioning points are provided on the outer edges of the four corner hole sealing gaskets of the existing detachable plate heat exchanger plates, which are used for plate assembly and positioning, and can effectively prevent the four corners of the plate from being misaligned in the working state. However, there is no positioning point for the heat exchange area inside the plate sealing gasket. The plate group is only restraine...
