Embodiment Construction

[0014] combine image 3 , Figure 4 , a plate heat exchanger plate with semi-cylindrical protrusions, including a plate main body, on which a positioning hole 1, a corner hole 2, a diversion area 3, a diversion area 4, and a heat exchange area 5 are arranged. The positioning holes 1 are located at both ends of the main body of the sheet for positioning. There are four corner holes 2 respectively located on the four corners of the plate main body, and the heat exchange medium flows through the corner holes 2 . The flow guide area 3 guides the heat exchange medium to the flow distribution area 4 . The split area 4 splits the heat exchange medium to different areas of the heat exchange area 5 . Corrugations 11 are arranged on the heat exchange area 5 along the flow direction of the heat exchange medium, and the corrugations are arranged symmetrically, that is, the identical plates rotate 180° and are completely pressed together. The shape of the corrugation 11 is one of horiz...

Abstract

The invention provides a plate heat exchanger sheet provided with spindle protrusions. The plate heat exchanger sheet comprises a sheet main body, the sheet main body is provided with corner holes, flow guide zones, flow distribution zones and a heat exchange zone, the heat exchange zone is provided with waves in the heat exchange medium flowing direction, and the valley portions of the waves areprovided with the spindle protrusions.

Description

technical field [0001] The invention relates to a heat exchanger plate technology, in particular to a plate heat exchanger plate with shuttle-shaped protrusions Background technique [0002] Compared with shell and tube heat exchangers, plate heat exchangers have high heat transfer coefficient, large logarithmic average temperature difference, small end temperature difference, small footprint, light weight, low price, convenient production, easy cleaning, and small heat loss. Not easy to scale and other advantages, often used in urban heating and cooling, petrochemical, waste heat recovery, food processing and other fields. Plate heat exchanger The plate is the most important part of the plate heat exchanger, and the design of the plate directly affects the heat exchange effect of the entire plate heat exchanger. [0003] The plate heat exchanger is composed of several identical plates in a certain order, usually as figure 1 The shown herringbone plate includes positioning...
