Detailed Description
Aiming at the problems of uneven flow field distribution and plate deformation in the prior art, the heat exchanger plate with the flow field adjusting structure is invented.
This application area flow field adjusts plate heat exchanger slab of structure, including ripple heat transfer district 1, corner hole 2, be equipped with the flow field in ripple heat transfer district 1 and adjust structure 3, the flow field is adjusted structure 3 and is horizontal rectangular structure, the flow field is adjusted structure 3 and is located the vertical non-central point in whole ripple heat transfer district and put, the flow field is adjusted the ripple of structure 3 and the ripple form or the ripple angle difference of adjacent ripple heat transfer district 1. The flow field regulating structure 3 extends transversely across the entire corrugated heat transfer zone. The corrugated heat exchange area is double-herringbone corrugated, the corrugated angle is large, the corrugated form of the flow field adjusting structure is herringbone corrugated, the corrugated angle is small, and the corrugated angle of the flow field adjusting structure 3 is smaller than that of the corrugated heat exchange area. The central line of the flow field adjusting structure divides the corrugated heat exchange area into two parts, and the length ratio of the two parts is 2: 3.

As shown in fig. 1-2, a flow field adjusting structure 3 is arranged in a corrugated heat exchange area 1 of a heat exchange plate of a plate heat exchanger. The flow field adjusting structure 3 is in a strip shape. The distance b from the longitudinal center line 4 of the flow field adjusting structure to one end of the corrugated heat transfer area is three fifths of the length a of the whole corrugated heat transfer area. The width c of the flow field conditioning structure is about 1/10 to 2/10 and greater than 80mm of the corrugated heat exchange area length a. The figure shows that the corrugation angle of the flow field adjusting structure is a small angle, the corrugation form is herringbone corrugation, the corrugation heat exchange area is a large angle, the corrugation form is double herringbone corrugation, when fluid flows through the flow field adjusting structure, the original flow direction is changed due to the difference between the corrugation form and the corrugation angle, secondary flow distribution of the fluid is achieved, the flow field is redistributed, and the plate plates can exchange heat more efficiently. Meanwhile, the rigidity of the plate is improved, and the condition of local deformation is improved.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the utility model should fall within the protection scope of the utility model.
