Detailed Description
The present invention will be described in further detail below with reference to the drawings and preferred embodiments, so that those skilled in the art can better understand the technical solutions of the present invention.
Referring to fig. 1, a plate of a single-side contactless straight-through runner of the present invention is composed of a main heat transfer surface 1, turbulence waves 2, pressure waves 3 and path-dividing waves 4. Referring to fig. 2 and 3, the turbulence wave 2 is a convex wave with respect to the main heat transfer surface 1, and the pressure-bearing wave 3 and the branching wave 4 are concave waves with respect to the main heat transfer surface. Referring to fig. 4 and 5, after a plurality of plates are stacked, at one side of the plates, the pressure-bearing corrugation 3 contacts with the pressure-bearing corrugation 3 to form a contact, the contact is connected in a welding manner to meet the pressure-bearing requirement, the branch corrugation 4 contacts with the branch corrugation 4, sealing can be realized in a welding manner to prevent fluid short circuit of a folding process, and at the other side of the plates, the height of the turbulence corrugation 2 is less than 1/2 of the interval between the plates, so that the turbulence corrugation 2 is opposite but does not form a corrugated contact in the flow passage after stacking.
With reference to fig. 1 and 2, fig. 3, fig. 4, and fig. 5, after a plurality of plates are stacked, one side of the plates forms a non-contact through flow channel, which is used as a flow channel of the medium a easy to be blocked or scaled, and the other side forms a contact flow channel, which is used as a flow channel of the medium B relatively clean or difficult to be scaled. The medium A directly passes through the non-contact direct flow channel, so that the medium flow channel basically does not deflect and change along the flowing direction, and the detention area does not appear in the flow channel due to no influence of the contact, and scaling or particulate blocking cannot occur. In addition, as the separation wave 4 is arranged on the plate, after a plurality of plates are stacked, the separation wave divides the medium B flow channel into two paths, the medium B flows in from the left end of the first path flow channel of the plate, flows out from the right end, flows in from the right end of the second path flow channel after being folded back through the pipe box arranged outside the plate stack, flows out from the left end, the medium A transversely passes through the non-contact flow channel, and the medium A and the medium B form wrong-flow heat exchange on two sides of the plate, so that the problem of temperature crossing of the medium A and the medium B can be solved without connecting a plurality of devices in series.
The pressure-bearing corrugation 3 solves the pressure-bearing problem of the plate through the contact, the contact is in one or combination of conical frustum shape, trapezoidal frustum shape and spherical crown shape with plane top, and is arranged in a grid or array mode, the reinforcing corrugation plays roles of reinforcing rigidity of the plate and reinforcing heat transfer through the turbulence corrugation, the corrugation form can be one or combination of spherical crown corrugation, strip corrugation and grid corrugation which are arranged along the medium circulation direction, and the corrugation height is less than 1/2 of the height of the flow channels between the plates and does not cause stagnation zone limitation.
It is apparent that when the direction of the pressure-receiving corrugation 3 and the turbulent corrugation with respect to the main heat transfer surface is changed, that is, the pressure-receiving corrugation is adjusted to be a convex corrugation with respect to the main heat transfer surface, and the turbulent corrugation is adjusted to be a concave corrugation or a convex corrugation with respect to the main heat transfer surface, as shown in fig. 2 and 3, the longitudinal flow path along the plate length direction becomes a non-contact through flow path after a plurality of plates are stacked. Further, when the plate has only the pressure-bearing ripple and the branch ripple without the turbulence ripple, and the characteristics of the pressure-bearing ripple and the branch ripple are the same as those described above, the plate having the innovative point of the present invention can still be constructed, and the plate should also be regarded as the protection scope of the present invention.
Referring to fig. 6, the branched wave 4 is opened at one end, a branched wave 5 is arranged in the opening area, the branched wave 5 plays a role in guiding the medium B, the medium B can turn back without flowing out of the plate, and accordingly, after the plate is assembled into a plate bundle, a pipe box is not needed to be arranged on the turning back side of the fluid. Accordingly, the shape of the bellows 4 may be circular arc or broken line, and the bellows may be continuous or intermittent.
Referring to fig. 7, the number of the branched corrugations 4 with m (m is even number) is set along the width direction of the plate, the B-side flow channel is divided into m+1-side flow channels along the width direction of the plate under the action of the branched corrugations 4, the medium B flows in from the left side of the first side, flows into the second side through the diversion of the branched corrugations 5, flows through the third side, … … and m side in sequence, and finally flows out of the plate from the right side of the m+1-side flow channel.
Referring to fig. 8, a number of n (n is an odd number) of branch corrugations 4 are provided along the width direction of the plate, the B-side flow channel is divided into n+1-side flow channels along the width direction of the plate under the action of the branch corrugations 4, medium B flows in from the left side of the first pass, flows into the second pass through the flow guide of the branch corrugations 5, flows through the third pass, … … and the nth pass in sequence, and finally flows out of the plate from the left side of the n+1-side flow channel.
Referring to fig. 9, support corrugations 6 and/or support bars 7 are provided at intervals along the length of the sheet. As shown in fig. 10 and 11, the supporting corrugation is a convex corrugation with respect to the main heat transfer surface 1, and the supporting function is provided for the medium a side stream after a plurality of plates are stacked. The support corrugations 6 and the support bars 7 may be continuous or intermittent, the number of which may be increased or decreased as required.
With reference to fig. 9, 10 and 11, the additional support corrugation 6 or support bar 7 is provided, the a side flow channel is only divided into a plurality of small through flow channels along the length direction of the plate, the flow form and flow uniformity of the medium a are not affected, and the characteristics of no retention area, no corrugation contact, uniform flow field and through flow channels are still provided, namely, after the additional support corrugation 6 or support bar 7 is provided, the anti-blocking and anti-scaling medium of the plate is identical to that when the plate is not provided. Further, the support corrugations 6 or the support bars 7 may be designed as a continuous or discontinuous structure.
Further, the pressure-bearing wave, the turbulence wave, the bending wave and the supporting wave forming the plate can be replaced by structural members such as columns, ribs and the like, so that a new plate is derived, the innovation and the novelty are the same as those of the invention, and the plate with the structure is also considered as the protection scope of the invention.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
