Abstract

The utility model relates to a parallel flow supercooling typed condenser, comprising a pair of collecting pipe, a liquid storage drier, a plurality of fin and a plurality of parallel flow supercooling typed condenser made of flat tube and arranged in parallel. The two ends of the flat tube are separately inserted into the collecting pipe which is perpendicular to and communicated with the flat tube. Fins are arranged between the flat tubes. Spacers are arranged between the collecting pipes. The utility model is characterized in that the collecting pipes are formed by welding there connection pipes with the liquid storage drier. Though the collecting pipe and the liquid storage drier are presented in external connection form, but also have integral property. The utility model has the characteristics that the structure is reasonable, the manufacturing process is optimized which leads that the entire brazing temperature of the condenser is uniform and the brazing temperature is reduced, the product qualification ratio is improved which is in favor of reducing the manufacturing cost and so on.

Description

A kind of concurrent flow Overcold condenser

Technical field

The utility model relates to a kind of used for automobile air conditioning condenser, especially relates to a kind of production technology optimization, heat exchange outstanding effect concurrent flow Overcold condenser.

Background technology

The condenser structure that automotive air-conditioning system is used is a lot, and its performance is different.Parallel flow condenser is the oval flat tube configuration of porous, form by flat heat exchange pipe and radiating fin, have louvre type bar seam on the radiating fin, every of flat tube blocks, respectively there is a header at two ends, cold-producing medium enters circular header by pipe joint, and shunting enters oval flat tube then, flows to the header on opposite abreast.Overcold condenser comprises condensation of refrigerant chipware part and crosses cold cooling chipware part, the liquid storage drier is placed in the condensation process of condenser, cold-producing medium is after the condensing zone heat exchange, flow into the liquid storage drier earlier, after flow into condenser again and continue heat exchange crossing the cold-zone, improve the cold-producing medium degree of supercooling, thereby improved the motorcar air conditioner refrigeration performance.As the term suggests the concurrent flow Overcold condenser is the condenser of comprehensive above structure.

Patent (the patent No.: 03228897.2) of " air conditioning for automobiles Overcold condenser " by name has been found in patent retrieval, patent (the patent No.: 02244612.5) of " Overcold condenser that reservoir separates ", they are by changing the position of liquid storage drier, the liquid storage drier is placed in the condensation process of condenser, cold-producing medium is after the condensing zone heat exchange, flow into the liquid storage drier earlier, after flow into condenser again and continue heat exchange crossing the cold-zone, improve the cold-producing medium degree of supercooling, thereby improved the air-conditioner refrigeration performance.But this class Overcold condenser all will pass through the long external liquid storage drier of connecting line, causes installation trouble, refrigerant to reveal, take deficiencies such as volume easily in vehicle.

Patent retrieval also find " a kind of cross cold mould parallel flow condenser " (patent No.: 02226885.5), its reservoir is an elongated tubular product such, and with a header soldering of condenser be one, reduced volume.But in the middle of actual production, when whole condenser enters the soldering furnace brazing, because reservoir is compared with the position that other need weld with the welding position of header, volume is a lot of greatly, need higher welding temperature, and the header volume of condenser other end is little, just do not need same high welding temperature, also have radiating fin all very thin, the words that welding temperature is equally high will be burnt fin, that is to say the position welding temperature words just of reservoir and header, the other end temperature burning again of condenser, so cause the bad control of welding temperature, qualification rate is low, the high deficiency of production cost.

The utility model content

In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of concurrent flow Overcold condenser.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of concurrent flow Overcold condenser is the concurrent flow Overcold condenser that is made of a pair of header, a liquid storage drier, some fins and some flat tubes that is arranged in parallel, its flat tube two ends insert perpendicular respectively and the header that communicates in, be provided with fin between described flat tube and the flat tube, be provided with partition in the middle of the described header, being connected to by three tube connectors of described header and liquid storage drier is welded.

As preferably, described fin is a zigzag, and its base portion is welded on the flat tube outer wall.

As preferably, described header is provided with installing hole, and the end of described flat tube is arranged in the installing hole; Be provided with the fin of windowing between the described flat tube.

As preferably, being connected to by external three short tubes of described header and liquid storage drier is welded into integral body, and tube connector is rounded, monolithic extruded or molding.

Therefore, though header of the present utility model and liquid storage drier are external form, possesses integraty again, have rational in infrastructurely, optimize production technology, make the integral braze-welded temperature of condenser even, reduced brazing temperature, improved product percent of pass, characteristics such as help reducing production costs.

Description of drawings

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

Specific embodiments

The utility model is described in further detail below in conjunction with embodiment:

With reference to shown in Figure 1, the utility model is made of header 4, liquid storage drier 7 and

tube connector

6,11,13, header 4 and liquid storage drier 7 are to be welded into an integral body by

tube connector

6,11,13, flat tube 3 is arranged on the header 4, the end of flat tube 3 is arranged in the installing hole of header 4, the Welding Structure that is connected to of fin 2 and flat tube 3.Be provided with the fin 2 of windowing between the flat tube 3.

During work, the HTHP superheated refrigerant steam that compressor is discharged enters the condenser condenses part from joint 1, and cold-producing medium enters circular header by pipe joint 1, and shunting enters oval flat tube then, flows to the header on opposite abreast.Header is segmentation, and the centre has partition to separate, and plays shunting and the effect of confluxing.Every section pipe number is unequal, and cold-producing medium is gaseous state when entering condenser, the specific volume maximum, and the pipe number is also maximum.Along with cold-producing medium is condensed into liquid gradually, its specific volume reduces gradually, and shared volume reduces gradually, the also corresponding minimizing of pipe number.Condenser is divided into the condensing zone part and crosses cold cooling zone part, the liquid storage drier is placed in the condensation process of condenser, cold-producing medium is after the condensing zone heat exchange, flow into the liquid storage drier through tube connector 6 earlier and carry out dry filter, after flow into condensers through tube connector 11 again and continue heat exchange crossing the cold-zone, improved the cold-producing medium degree of supercooling, make the dischargeable capacity of condenser obtain the most reasonable utilization, improve heat exchange efficiency, reduced the refrigerant side flow resistance.Emit heat by heat radiating flat tube and give condenser outer air, flow out from joint 12 thereby make overheated gaseous refrigerant be condensed into liquid refrigerant.

At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
