Abstract
The utility model relates to a channel chevron sealing tape in a plate-fin heat exchanger. The channel chevron sealing tape comprises a strip-shaped structure body, wherein the upper surface and the lower surface of the structure body are parallel, the side face of one side and the upper surface and the lower surface of the structure body are vertical, and the other side of the structure body is longitudinally provided with two inwardly-concave V-shaped grooves along the structure body; and the two V-shaped grooves are symmetrically arranged, and the middle of the two V-shaped grooves form a convex A-shaped raised line. The channel chevron sealing tape in the plate-fin heat exchanger provided by the utility model has the advantages that the V-shaped grooves and the A-shaped raised line are adopted, on the one hand, the contact area between the hot fluid and the sealing tape is greatly increased, and the heat transfer efficiency of the sealing tape is improved; and on the other hand, the A-shaped raised line plays the function of a strengthening rib, the ability of resistance to the deformation of a sealing tape body is improved, and the mechanical strength is greatly improved.
Description
Technical field
The utility model 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 comprised of plate and fin heat transfer element.Have the advantages such as heat transfer efficiency height, advantages of compact and light structure, strong adaptability.
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 on the one hand heat-conducting area, structural strength is also lower on the other hand, and the position of strip of paper used for sealing produces mechanically deform easily.
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 problems to be solved in the utility model.
The utility model content
The purpose of this utility model is for above-mentioned technical problem, and 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 is provided.
The purpose of this utility model is to be achieved through the following technical solutions:
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 described structural body is parallel with lower surface, the side of one side of structural body and upper surface, lower surface are vertical, the opposite side of structural body is along the V-shaped groove that vertically has two indents of structural body, two described V-shaped grooves are arranged symmetrically with, and form the A shape raised line of a projection in the middle of two V-shaped grooves.
The surface of described A shape raised line is round and smooth surface.
The position of the bottom land of described V-shaped groove is made as circular-arc transition.
The degree of depth of described 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 described in the utility model, adopt V-shaped groove and A shape raised line, increased greatly on the one hand the contact area of hot fluid and strip of paper used for sealing, 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
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of plate-fin heat exchanger internal channel chevron strip of paper used for sealing described in the utility model.
The specific embodiment
As shown in Figure 1, the described plate-fin heat exchanger internal channel of the utility model embodiment chevron strip of paper used for sealing, the structural body 1 that comprises strip, the upper surface of described 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 arranged symmetrically with along 2, two described V-shaped grooves 2 of the V-shaped groove that vertically has two indents of structural body, and forms the A shape raised line 3 of a projection in the middle of two V-shaped grooves 2.
The surface of described A shape raised line 3 is round and smooth surface.
The position of the bottom land of described V-shaped groove 2 is made as circular-arc transition.
The degree of depth of described 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 described in the utility model, adopt V-shaped groove and A shape raised line, increased greatly on the one hand the contact area of hot fluid and strip of paper used for sealing, 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.
