Abstract
The invention discloses an antisymmetrical step flat tube. Two passages for refrigerant to flow are arranged in the flat tube along the transverse direction of the flat tube. A plurality of radiating grooves along the passages are arranged on the external surface of the upper wall of the flat tube. A first step adjacent to the upper wall of the flat tube is arranged on one side surface of the flat tube in parallel with the passages. A second step adjacent to the lower wall of the flat tube is arranged on the other side surface opposite to one side surface of the flat tube. Each of the first step and the second step is provided with a baffle and a limiting plate which are sequentially arranged at intervals from the inside to the outside along the transverse direction of the flat tube. A plurality of limiting grooves are arranged on the internal side of each limiting plate. The spacing between the baffle and the limiting plate on the first step is fit with the thickness of the limiting plate on the second step. The flat tube provided by the invention has good compression strength and high heat exchange efficiency, and fins of a heat exchanger which is assembled by using the flat tube can be omitted.
Description
Technical field
The invention belongs to field of heat exchangers, be specifically related to the antisymmetry ladder flat tube that a kind of heat exchanger is used.
Background technology
Heat exchanger is made up of header, flat tube, fin usually; The flat tube set inside is useful on the passage that fluid flows; Its entrance and exit is connected respectively to header; On the flat tube outer wall, welding fin, fin is separated flat tube and flat tube on the one hand, and the gaseous fluid and the interior fluid of flat tube of flowing through on the other hand between fin and the fin carry out heat exchange.Fig. 1 is a kind of flat tube before; In this flat tube, be provided with several passages 1 to direction along the flat tube groove; Can find out from figure, under the certain situation of flat tube cross-sectional area, normally be the raising heat exchange efficiency through the cross-sectional area that increases passage; This must cause the flat tube wall thickness to reduce, and influences the compressive resistance of flat tube.
Summary of the invention
The object of the invention is existing flat tube is carried out structure optimization, and a kind of antisymmetry ladder flat tube that compressive resistance can improve heat exchange efficiency again that promptly do not reduce is provided.
The present invention realizes that technical scheme that above-mentioned purpose adopts is as above:
A kind of antisymmetry ladder flat tube is provided with two passages that are used for cold-producing medium circulation along the flat tube horizontal direction in flat tube, be provided with several radiating grooves along channel direction at the outer surface of flat tube upper wall;
On the flat tube side that parallels with channel direction therein first ladder near the flat tube upper wall is set, second ladder near the flat tube lower wall is set on the another side relative with this flat tube side;
On said first ladder and second ladder all along the flat tube horizontal direction by interior baffle plate and the limiting plate of being arranged at intervals with successively outward, be provided with several stopper slots in the inboard of limiting plate;
The thickness of the limiting plate on the baffle plate on first ladder and the spacing of limiting plate and second ladder matches.
Beneficial effect:
Radiating groove in that the flat tube upper wall is provided with promptly can increase the area that flat tube carries out heat exchange, can not reduce the compressive resistance of wall again; When range upon range of, radiating groove can also play the effect of fin with flat tube, thereby can save fin with the heat exchanger of this flat tube assembling;
Two passages only are set in flat tube; And baffle plate being set in the side, the fluid that helps like this in the passage carries out heat exchange through flat tube side and flat tube fluid outward, has increased heat exchange area; Baffle plate and the mutual screens of limiting plate through the side realize the connection side by side of a plurality of flat tubes;
Flat tube of the present invention has good compressive resistance and high heat exchange efficiency.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is further specified.
Shown in Fig. 1-3, the same with the flat tube of having lived, flat tube of the present invention also is to be processed by aluminium.
Flat tube of the present invention has following structure; The thickness of flat tube generally is controlled at 1 with the ratio of the width of flat tube: (3～5); Width with flat tube serves as that laterally broad ways is offered two passages arranged side by side 1 in flat tube, and the width of passage 1 cross section is 1.5:1 with the ratio of height; The direction of passage 1 and the length direction of flat tube parallel, and the port of passage 1 is connected with header respectively.In order to increase the heat exchange area on flat tube surface; On the outer surface of flat tube upper wall, be provided with some the radiating grooves 11 of indentation, the wide and dark ratio of every groove is 1:1, the general 3～5mm of groove depth; The direction of radiating groove 11 is identical with the direction of passage 1, and radiating groove 11 mainly is distributed in the top of passage.Flat tube side paralleling with channel direction is respectively equipped with ladder; The height of ladder and the height of flat tube be 1: (4～5); Wherein, First ladder 111 is to extend to one of them side by matrix with the upper wall 12 of flat tube to be formed, and second ladder 101 is that the lower wall 10 with flat tube is formed to another relative side extension by matrix.Along the flat tube horizontal direction; On first ladder, by interior baffle plate 2 and the limiting plate 3 of being provided with respectively outward, leave spacing between baffle plate 2 and the corresponding flat tube side, this spacing is generally 2～5mm; Make the outer fluid of flat tube carry out heat exchange by the fluid in this and flat tube; Equally, on second ladder along the flat tube horizontal direction by interior baffle plate 2 and the limiting plate 3 of also being provided with respectively outward, limiting plate 3 leans on the face of baffle plate 2 one sides to be provided with several stopper slots 31; Stopper slot 31 directions are parallel to channel direction, and the baffle plate and the limiting plate of the baffle plate of first ladder and limiting plate and second ladder have axisymmetric relation.When a plurality of flat tubes are united when using, the limiting plate on a flat tube first ladder is wherein snapped between the baffle plate and limiting plate on another flat tube second ladder, fix through the mutual interlock of the stopper slot on the limiting plate.
