Abstract

The invention discloses a three-part combined radiating tube. A radiating tube body has an inner fin A and two inner fins B symmetrically arranged inside, wherein the inner fin A is a rectangular frame structure formed by inwards bending the middle of an A large surface of the radiating tube body and then respectively bending the middle to the two sides of the tube body in the width direction; the inner fins B with rectangular wave structures are mounted between the inner fin A and the ends of the tube body in the width direction; and such multiple key bearing parts or stress concentration parts as the symmetric center line part of the radiating tube body, the two side end parts of the radiating tube and the tube wall are two-layer material composite structures, so that the structure strength and the bearing strength are improved.

Description

Three component combination radiating tubes

Technical field

The present invention relates to a kind of radiating tube, especially relate to a kind of three component combination radiating tubes.

Background technology

The air-conditioning condenser radiating tube that current truck, passenger vehicle, engineering machinery, farming equipment etc. mate, most employing extrudate, adopt plug inner fin structure radiating tube, this structure radiating tube scale error is larger, material thickness became uneven, cause assembling difficulty, the structural strength of product is low, the uniformity of product is poor, and it bears, and system pressure is lower, radiating efficiency is lower.

Summary of the invention

The object of the invention is: a kind of structural strength and the high three component combination radiating tubes of bearing strength are provided.

Technical scheme of the present invention is: comprise heat radiation body and inner fin, heat radiation tubular body has inner fin A and two symmetrically arranged inner fin B, inner fin A is the inside bending of the large Middle face of A of heat radiation body and is bent into rectangle frame structure respectively to body both sides in the width direction, between two rectangle frames, plane coordinates formation two-layer composite, rectangle frame coordinates with the large facial plane of B and forms two-layer composite, the inner fin B of square wave structure is housed between inner fin A and body width end, between the rectangle frame of inner fin A and the square wave of inner fin B, plane coordinates and forms two-layer composite, the square wave end of inner fin B is bent into the arc structure coordinated with radiating tube end, large of crest and the A of square wave and the large facial plane of B coordinate and form two-layer composite, inner fin A and inner fin B forms the cavity of multiple cooling medium that independently circulates at heat radiation tubular body.

The square wave of described inner fin B forms through repeatedly bending, the square wave of the inner fin B of every side and form multiple cavity between large of A and large of B.

Further, inner fin B square wave end semicircular in shape structure, to coordinate with radiating tube end and form semicircle two-layer composite.

The invention has the beneficial effects as follows: the present invention due to heat radiation body and inner fin all use Rolling compund material, the uniform wall thickness of material therefor is consistent, material inside organization is fine and close, the self-strength of material is high, inner fin A is the inside bending of the large Middle face of A of heat radiation body and is bent into rectangle frame structure respectively to body both sides in the width direction, the inner fin B of square wave structure is housed between inner fin A and body width end, inner fin A and inner fin B forms the cavity of multiple cooling medium that independently circulates at heat radiation tubular body, project organization is reasonable, radiating efficiency is high, in heat radiation body symmetrical center line position, crucial pressure-bearing position, the first-class many places of radiating tube both side ends, tube wall or stress concentration portion position be materials at two layers composite construction, and improve structural strength and bearing strength, its structural strength can improve more than 2 ~ 3 times, adopt condenser of the present invention, its structural strength and bearing strength are largely improved, and pressure-bearing can reach more than 12MPa.The present invention can realize suitability for industrialized production, and by special equipment through repeatedly shaping, be once welded through soldering oven, production efficiency is high, is applicable to more large batch of production.

Detailed description of the invention

To dispel the heat the structural representation of body and inner fin part A, the structural representation of Fig. 3 inner fin part B as can be seen from structural representation of the present invention shown in Fig. 1, Fig. 2, the present invention by dispel the heat body and heat radiation tubular body inner fin A6, two symmetrically arranged inner fin B2 totally three parts form, radiator pipe material is the two-sided composite of rolling, that is: solder layer/mother metal layer/solder layer.Inner fin A6 be heat radiation body the large face 1 of A in the middle part of inwardly bending be bent into rectangle frame 4 structure respectively to body both sides in the width direction, heat radiation body and inner fin A6 through special equipment by sheet metal through repeatedly folding forming, the rectangle frame 4 of two " mouth " word structures is wrapped in tubular body, between two rectangle frames 4, plane coordinates and forms two-layer composite, and rectangle frame 4 coordinates with B large face 3 plane and forms two-layer composite.The inner fin B2 of square wave structure is housed between inner fin A6 and body width end, and inner fin B2 is plugged between inner fin A6 and body end, and inner fin B2 is symmetrical for two, left and right.At heat radiation tubular body, between the rectangle frame 4 of inner fin A6 and tube wall, between the B square wave of inner fin B2 and tube wall, form multiple independently cavity 7, internal circulation cooling medium.In the present embodiment, the square wave of inner fin B2 is six bendings, the square wave of the inner fin B2 of every side and form three cavitys between the large face of A 1 and the large face 3 of B, the rectangle frame 4 of inner fin A6 and the square wave of inner fin B2 form eight independently cavitys 7 at heat radiation tubular body, and between the rectangle frame 4 of inner fin A6 and the square wave of inner fin B2, plane coordinates and forms two-layer composite.The crest of square wave coordinates with the large face of A 1 and B large face 3 plane and forms two-layer composite, the square wave outer end of inner fin B2 is bent into the arc structure 5 coordinated with radiating tube end, square wave outer end semicircular in shape structure, coordinates with radiating tube both side ends and forms semicircle two-layer composite.In heat radiation body symmetrical center line L position, crucial pressure-bearing position, the first-class many places of radiating tube both side ends, tube wall or stress concentration portion position be that materials at two layers composite welding is integrated, and can significantly improve structural strength and bearing strength.Inner fin A6 and inner fin B2 is adopted as matched in clearance with heat radiation body, and fit clearance is not more than 0.15mm, is convenient to assembling, is once welded by soldering oven.
