Abstract

The utility model relates to a double rows porous flat tube parallel flow condenser, comprising an upper and a lower collecting pipe, a tee joint, a porous flat tube, a cooling fin, and a septum. The upper and the lower collecting pipes are provided with two respectively, the upper collecting pipe is connected with the lower collecting pipe by the tee joint, a plurality of porous flat tubes in parallel arrangement are provided between the two upper collecting pipes or the two lower collecting pipe respectively. The collecting pipes are divided by the septum; the whole strip cooling fin is welded between the two rows of the porous flat tubes. When working, a refrigerant is arrived into the double rows porous flat tube through the tee joint at the same time, under the separation of the septum, the refrigerant passes through the double layers porous flat tubes orderly and in parallel and flows out off the other thee joint, with good application effect.

Description

A kind of double porous flat pipe parallel flow condenser

The utility model relates to a kind of condenser, especially a kind of double porous flat pipe parallel flow condenser.

Present most minibus, hvac system adopt serpentine condenser more, and for satisfying the refrigeration requirement, the volume of condenser is all bigger, has not only increased vehicle weight, has also wasted resource.For overcoming the deficiency of serpentine condenser, there are part mini-bus, passenger vehicle to begin to adopt individual layer porous flat pipe parallel flow condenser at present, improved 30% refrigerating capacity, under the requirement of satisfying refrigeration performance, but weight reduction, economical with materials.But weak point is the restriction that is subjected to the concurrent flow manufactured materials, its thickness is all below 22mm, with a condenser, refrigeration performance does not often reach requirement yet, for overcoming deficiency, have to use two condensers, but increased installation difficulty, and the fin of two condensers is independent, the pitch of waves can not align, increase air resistance coefficient, influenced refrigeration.

The purpose of this utility model, being provides a kind of compact conformation at above-mentioned the deficiencies in the prior art part, easy for installation, the double porous flat pipe parallel flow condenser of good refrigeration effect.

The utility model is achieved in that it is made up of upper and lower header, porous flat pipe, fin, partition, end cap and three-way connection.Header has four, be arranged in parallel.Wherein going up header has two, and lower header has two, and an end is communicated with three-way connection between the upper and lower header, and the other end is sealed by end cap.Two are upward connected by some porous flat pipes between the header, are also connected by some porous flat pipes between two lower header, and folder welds the whole piece fin between two row's porous flat pipes, and fin is the individual layer fin that has shutter.Be provided with partition between header and separate, play shunting and the effect of confluxing.During work, refrigerant enters double porous flat pipe simultaneously from three-way pipe, under the obstruct of partition, refrigerant is in order abreast by double-layer porous flat tube, by porous flat pipe and the conduction of fin heat, make cold-producing medium progressively become liquid state by gaseous state, flow out from another threeway outlet then, the utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A cutaway view.

Among the figure, the 1st, last header, the 2nd, lower header, the 3rd, three-way connection (inlet), the 4th, porous flat pipe, the 5th, fin, the 6th, partition, the 7th, three-way connection (outlet), the 8th, end cap.

The utility model is made up of last header 1, lower header 2, three-way connection 3, porous flat pipe 4, fin 5, partition 6, three-way connection (outlet) 7 and end cap 8.

Referring to Fig. 1 and Fig. 2, between last header 1 and the lower header 2 end by three-way connection 3 together with, its other end is sealed by end cap 8; Between the last header 1, connected by some parallel porous flat pipes 4 between the lower header 2, upper and lower header is provided with some partitions 6, the effect of playing shunting and confluxing; Folder weldering whole piece fin 5 between two row's porous flat pipes 4, fin 5 is the individual layer fins that have shutter, during work, refrigerant enters double porous flat pipe 4 simultaneously by three-way connection 3, under the obstruct of partition 6, pass through porous flat pipe 4 in order, abreast, by the heat conduction of porous flat pipe 4 and fin 5, cold-producing medium progressively becomes liquid state by gaseous state, flows out from three-way connection 7 then.The utility model is actually two parallel flow condensers is connected into an integral body, fin is that the whole piece folder is welded between the double porous flat pipe, the waveform neutral gear is straight-through, has avoided two condensers to press from both sides the weldering fin respectively and neutral gear is difficult for alignment and increase the defective of windage, and radiating effect improves.

Claims

1, a kind of double porous flat pipe parallel flow condenser, formed by last header, lower header, three-way connection, porous flat pipe, fin and partition, it is characterized in that the described header of going up is provided with two, lower header is provided with two, be communicated with by three-way connection between last header and the lower header, go up between the header for two and connect by some the porous flat pipes that be arranged in parallel, also connect folder weldering whole piece fin between two row's porous flat pipes between two lower header by some the porous flat pipes that be arranged in parallel.

2, a kind of double porous flat pipe parallel flow condenser according to claim 1 is characterized in that being provided with some partitions in the described upper and lower header pipe.
