Abstract

The utility model relates to a parallel-flow type condenser with large-caliber collecting pipe, comprising two large-caliber collecting pipes 1 with over 40 mm diameter, a plurality of porous flat tubes 4 and a plurality of heat sinks 5. A plurality of splitters are arranged in the collecting pipes 1. The collecting pipes are communicated with each other through a plurality of parallel porous flat tubes. The heat sinks 5 with louver is welded between the porous flat tubes 4. Under the blocking of the splitters, the refrigerant flows in the porous flat tubes parallelly and orderly at work. The utility model has the advantages of good refrigeration, lower production cost and that can be suitable for air-conditioning system of buses.

Description

A kind of heavy caliber header parallel flow condenser
The utility model relates to a kind of header parallel flow condenser, the heavy caliber header parallel flow condenser that especially a kind of automobile is used.
The air-conditioning system of present most minibus, passenger vehicle adopts serpentine condenser more, and for satisfying refrigeration performance, the volume of condenser is all bigger, has not only increased vehicle weight, has also wasted resource.In order to overcome the deficiency of serpentine condenser, there are part minibus, passenger vehicle to begin to adopt at present more advanced parallel flow condenser to replace serpentine condenser at present, the condenser of this structure and the serpentine condenser of equal volume have relatively improved 30% refrigerating capacity, under the requirement of satisfying refrigeration performance, but weight reduction, save weight.Thickness is only arranged at present is this series products below 22 millimeters but with interior.With a refrigerator, refrigeration performance does not often reach requirement, must or connect with two above condenser parallel connections, refrigerating capacity can reach requirement like this, but if in parallel the use, the fin of two condensers is independent, the pitch of waves can not align, and has increased air resistance coefficient, thereby has influenced refrigeration; If series connection is used, increased connecting tube and cost, install and keep in repair difficulty more.
The purpose of this utility model is the problem at above-mentioned existence, and a kind of heavy caliber header parallel flow condenser is provided, its compact conformation, simple, install and keep in repair more convenient, good refrigeration effect.
The utility model is achieved in that it is made up of two heavy caliber headers, some porous flat pipes and fin.The header two ends are by being provided with end cap seal, and its inside is provided with some partitions header is divided into plurality of sections, the effect of playing shunting in the course of the work and confluxing.Use porous flat pipe between two headers, claim harmonica-shaped tube to connect again, be communicated with folder weldering fin between the porous flat pipe, fin band shutter by some parallel porous flat pipes between the corresponding partition section of each between two headers.
During work, refrigerant enters from the header inlet, and parallel mobile between porous flat pipe in an orderly manner under the obstruct of partition, by porous flat pipe and the conduction of fin heat, cold-producing medium progressively becomes liquid state by gaseous state, exports away from header then.
The parallel flow condenser of this structure increases the area of dissipation of refrigerant by the sectional area that strengthens porous flat pipe, the fin whole piece folder that has shutter is welded between the porous flat pipe, the waveform neutral gear is straight-through, be difficult for the defective that alignment increases windage and influences radiating effect because of folder welds the fin neutral gear when having avoided two condensers in parallel, problem, the problem includes: increase connecting tube, increasing production cost and problems such as installation and maintenance difficult when also having avoided two condenser series connection.
Below in conjunction with drawings and Examples the structure of the present utility model and the course of work are further described.
Fig. 1 is the utility model structural representation, and accompanying drawing also makes an abstract.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, the 1st, header, the 2nd, partition, the 3rd, end cap, the 4th, porous flat pipe, the 5th, fin, the 6th, refrigerant inlet, the 7th, refrigerant exit.
Referring to Fig. 1, the utility model is made up of two heavy caliber headers 1, some porous flat pipes 4 and fin 5.Header 1 two ends are by being provided with end cap 3 sealings, and its inside is provided with some partitions 2 header 1 is separated into plurality of sections, the effect of playing shunting in the course of the work and confluxing.With some porous flat pipes 4, claim harmonica-shaped tube to connect again between two headers 1, be communicated with by some parallel porous flat pipes 4 between each corresponding partition section that two headers are 1.Referring to Fig. 2, folder weldering fin 5 between the porous flat pipe 4, fin 5 band shutters.
During work, refrigerant enters from header refrigerant inlet 6, and is parallel mobile 4 of porous flat pipes in an orderly manner under the obstruct of partition 2, and by porous flat pipe 4 and fin 5 heat conduction, cold-producing medium progressively becomes liquid state by gaseous state, goes out from header refrigerant exit 7 then.
In the utility model embodiment, header 1 adopts diameter 40 millimeter tube, and the specification of porous flat pipe 4 is 3 * 36 millimeters.
The utility model is simple in structure, install and keep in repair more convenient, good refrigeration effect, production cost is low, the air-conditioning system that is fit to minibus, passenger vehicle is used.

Claims (3)

1, a kind of heavy caliber header parallel flow condenser, formed by two heavy caliber headers 1, some porous flat pipes 4 and fin 5, it is characterized in that header 1 two ends are by being provided with end cap 3 sealings, any header two ends up and down respectively is provided with a refrigerant inlet and a refrigerant exit, every header the inside is respectively arranged with some partitions 2 header 1 is separated into plurality of sections, is communicated with by the some porous flat pipes that be arranged in parallel 4 between the corresponding partition section of each between two headers.
