Abstract
The utility model discloses a flat pipe of parallel flow condenser, the inside cooling path's of flat tub of body both sides are equipped with the arc passageway, cooling path's middle part is equipped with the triangle -shaped passageway, and the bottom surface of one of them triangle -shaped passageway and the top line of another triangle -shaped passageway are at the coplanar. It is parallel to follow the outline line outside pitch arc on the arc passageway and the flat tub of both sides. This technical scheme heat exchange coefficient is high, and convex section structure is adopted at flat tub of both ends, has fully increased the area of contact of refrigeration and flat pipe, has promoted parallel flow condenser's whole heat transfer volume.
Description
Technical field:
The utility model relates to a kind of parallel flow condenser flat tube, is specially adapted to refrigerating field uses.
Background technology:
Current parallel flow condenser flat tube has compact conformation, the coefficient of heat transfer is high, the advantages such as matter is lightweight, refrigerant charge is low, the refrigerant passage of existing condenser flat tube often adopts rectangle and circular two kinds, when adopting rectangular cross-sectional, to cross the contact area of rectangular cross-sectional and flat tube less than normal for flow of refrigerant, corresponding heat exchange area is corresponding reduction also, though the second circular cross-section increases, but the fin close together that the top of circular cross-section and bottom are connected with flat tube, remaining region and fin close together, cause fin efficiency low, heat exchange property reduces.
Summary of the invention:
Task of the present utility model is that the proposition coefficient of heat transfer is high, promotes a kind of parallel flow condenser flat tube of condenser overall heat exchange amount.
Task of the present utility model completes like this, a kind of parallel flow condenser flat tube, it is characterized in that: the both sides of the inside refrigerant passage of flat tube body are provided with curved channel, the middle part of described refrigerant passage is provided with triangular duct, and the top line of the bottom surface of one of them triangular duct and another triangular duct is at same plane.Camber line on described curved channel is parallel with outer, flat tube both sides outline line.Described triangular duct cross section is class isosceles triangle, and the centre distance of adjacent two isosceles triangles is not less than 0.1mm.
The utility model has following effect: the technical program coefficient of heat transfer is high, and flat tube two ends adopt circular section structure, substantially increases the contact area of refrigeration and flat tube, improves the overall heat exchange amount of parallel flow condenser.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
The technical program is made up of flat tube body 3, refrigerant passage 4, curved channel 1 and triangular duct 2.Specific embodiment as shown in Figure 1, the both sides of the inside refrigerant passage 4 of flat tube body 3 are provided with curved channel 1, camber line on described curved channel 1 is parallel with outer, flat tube both sides outline line, the middle part of described refrigerant passage 4 is provided with triangular duct 2, the top line of the bottom surface of one of them triangular duct and another triangular duct is at same plane, described triangular duct cross section is class isosceles triangle, the centre distance of adjacent two isosceles triangles is not less than 0.1mm, furtherly: centre distance can equal also can be unequal, the cross section of adjacent two class isosceles triangles can equal also can be unequal.Described triangular-section port number more than at least 2.Furtherly: the triangular duct arranged in the middle part of refrigerant passage does not connect each other, the arc surface of the bottom surface of triangular duct 2 and curved channel 1 is apart from the outer surface of flat tube body 3 apart from equal, and this flat tube body is one-body molded by hot extrusion by aluminium alloy.
The technical program adopts curved channel and triangular duct in the refrigerant passage of condenser flat tube, the two combines, add the contact area of cold-producing medium and flat tube on the one hand, make cold-producing medium and the abundant heat exchange of flat tube, the bottom surface of triangular duct is parallel with flat tube top and bottom on the other hand, the fin pitch that cold-producing medium is connected with flat tube from significantly diminishing, thus improves the heat exchange amount of condenser entirety.
