Embodiment Construction

[0013] combine figure 2 , image 3 , a new fishbone-shaped plate heat exchanger plate, including a plate body, the plate body is provided with positioning holes 1, corner holes 2, diversion area 3, diversion area 4, heat exchange area 5. 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,

[0014] When the heat exchange medium flows into the plate through the corner hole 2, passes through the diversion area 3 and the diversion area 4, and flows into the heat exchange area 5, where ...

Abstract

The invention provides a fishbone-shaped novel plate heat exchanger plate. The fishbone-shaped novel plate heat exchanger plate comprises a plate body; an angle hole, a guide area, a shunting area anda heat exchange area are arranged on the plate body; ripples are arranged on two sides of the axis of the flowing direction of a heat exchange medium in the heat exchange area; included angles are formed between the ripples on the same side and the axis of the heat exchange area; plane troughs are arranged between the adjacent ripples on the same side; and the ripples on different sides are staggered left and right along the axis of the heat exchange area.

Description

technical field [0001] The invention relates to a heat exchanger plate technology, in particular to a new fishbone-shaped plate heat exchanger plate. 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. 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 holes 1 , corner holes 2 , diversion area 3 , diversion area 4 , heat exchange area 5 , front small corrugations 6 , rea...
