Abstract
The invention provides an internal channel hill-shaped sealing strip of a plate-fin heat exchanger. The internal channel hill-shaped sealing strip comprises a long-strip-shaped structure body, wherein an upper surface of the structure body is in parallel to a lower surface; a side face of one side of the structure body is vertical to the upper surface and the lower surface, and two inwards concave V-shaped grooves are formed and symmetrically arranged at the other side of the structure body along a longitudinal direction of the structure body; and an A-shaped convex strip is formed between the two V-shaped grooves. According to the internal channel hill-shaped sealing strip of the plate-fin heat exchanger, the V-shaped grooves and the A-shaped convex strip are adopted, thus a contact area of hot liquid and the sealing strip is increased, and the heat transmission efficiency of the sealing strip is improved, and on the other hand, the A-shaped convex strip serves as a reinforcing rib, so that a deforming resistance capacity of the sealing strip main body is improved, and the mechanical strength is greatly improved.
Description
Technical field
The present invention relates to a kind of plate-fin heat exchanger internal channel chevron strip of paper used for sealing, is the obturator of plate-fin heat exchanger.
Background technology
The heat exchanger that plate-fin heat exchanger is made up of plate and fin heat transfer element.Have advantages such as heat transfer efficiency height, advantages of compact and light structure, adaptability be strong.
The strip of paper used for sealing of existing plate-fin heat exchanger all is the solid construction Al-alloy parts that adopts rectangle; The heat transfer efficiency of strip of paper used for sealing itself is very low, and adopts the solid construction of rectangle, has reduced heat-conducting area on the one hand; Structural strength is also lower on the other hand, and the position of strip of paper used for sealing is easy to generate mechanically deform.
Based on foregoing, how the strip of paper used for sealing that a kind of mechanical strength is high, heat transfer efficiency is good is provided, be the technical problem that the present invention will solve.
Summary of the invention
The objective of the invention is provides the plate-fin heat exchanger internal channel chevron strip of paper used for sealing that a kind of mechanical strength is high, heat transfer efficiency is good to above-mentioned technical problem.
The objective of the invention is to realize through following technical scheme:
A kind of plate-fin heat exchanger internal channel chevron strip of paper used for sealing; The structural body that comprises strip; The upper surface of said structural body is parallel with lower surface, and the side of a side of structural body and upper surface, lower surface are vertical, and the opposite side of structural body is along the V-shaped groove that vertically has two indents of structural body; Two said V-shaped groove symmetric arrangement, and in the middle of two V-shaped grooves, form a protruding A shape raised line.
The surface of said A shape raised line is slick and sly surface.
The position of the bottom land of said V-shaped groove is made as circular-arc excessive.
The degree of depth of said V-shaped groove is no more than 3/4ths of structural body width.
Plate-fin heat exchanger internal channel chevron strip of paper used for sealing of the present invention; Adopt V-shaped groove and A shape raised line; Increased the contact area of hot fluid and strip of paper used for sealing on the one hand greatly, improved the heat transfer efficiency of strip of paper used for sealing, A shape raised line has played the effect of reinforcement on the other hand; Can improve the ability of strip of paper used for sealing body resistance to deformation, mechanical strength can increase substantially.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structure chart of plate-fin heat exchanger internal channel chevron strip of paper used for sealing according to the invention.
The specific embodiment
As shown in Figure 1; The described plate-fin heat exchanger internal channel of embodiment of the invention chevron strip of paper used for sealing comprises the structural body 1 of strip, and the upper surface of said structural body 1 is parallel with lower surface; The side of one side of structural body 1 and upper surface, lower surface are vertical; The opposite side of structural body 1 is along 2, two said V-shaped groove 2 symmetric arrangement of the V-shaped groove that vertically has two indents of structural body, and in the middle of two V-shaped grooves 2, forms a protruding A shape raised line 3.
The surface of said A shape raised line 3 is slick and sly surface.
The position of the bottom land of said V-shaped groove 2 is made as circular-arc excessive.
The degree of depth of said V-shaped groove 2 is no more than 3/4ths of structural body 1 width.
Plate-fin heat exchanger internal channel chevron strip of paper used for sealing of the present invention; Adopt V-shaped groove and A shape raised line; Increased the contact area of hot fluid and strip of paper used for sealing on the one hand greatly, improved the heat transfer efficiency of strip of paper used for sealing, A shape raised line has played the effect of reinforcement on the other hand; Can improve the ability of strip of paper used for sealing body resistance to deformation, mechanical strength can increase substantially.
