Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Shown in seeing figures.1.and.2, Fig. 1 is the structural representation of coolant distribution device first embodiment of the present invention, and Fig. 2 is the structural representation of distributor in Fig. 1.The coolant distribution device that the present embodiment provides comprises header 10, the flat tube 20 be communicated with this header 10 and the input pipe 30 for inputting refrigerant, be provided with at least one dividing plate 101 in header 10 and this header 10 is separated to form some chambers 102, each chamber 102 is all communicated with some flat tubes 20, and each chamber 102 is communicated with input pipe 30 respectively by tube connector 40.
In the present embodiment, in above-mentioned each chamber 102, all one tube connector 40 can be set one_to_one corresponding, and this tube connector 40 runs through dividing plate 101 is communicated with input pipe 30.
This header 10 is separated to form some chambers 102 by arranging dividing plate 101 by the present invention, and arranges a tube connector 40 in each chamber 102, and this tube connector 40 is communicated with input pipe 30.Thus when refrigerant flow to input pipe 30 place, thus punish at input pipe 30 and tube connector 40 and flow, flowed into the chamber of correspondence after making coolant distribution by tube connector 40 respectively, then carry out heat exchange in inflow flat tube 20.Due to before inflow header 10, by the coolant distribution in tube connector 40 pairs of input pipes 30, therefore the cold medium flux flowing into each chamber 102 can be made substantially to be consistent, the flow flowing into refrigerant in each flat tube 20 can be made substantially to be consistent, thus improve the heat exchange efficiency of flat tube 20, and then improve the heat exchange efficiency of heat exchanger.
It should be noted that in the present embodiment, the distance between the quantity of aforementioned barriers 101 and adjacent separator 101 can be arranged according to actual needs, is not further limited at this.As in preferred the present embodiment, the distance between adjacent two dividing plates 101 is equal, and the quantity of flat tube 20 corresponding to each chamber 102 is equal.
Particularly, above-mentioned input pipe 30 can all be connected with a distributor 50 with tube connector 40, thus by the coolant distribution in input pipe to each tube connector 40, and flowed in corresponding chamber 102 by tube connector 40.Such as, one end of header 10 is provided with the blanking cover for sealing this one end, the other end is provided with the distributor 50 of header 10 adaptation and this distributor 50 seals the other end of this header 10, this distributor 50 has the internal pipeline 501 be communicated with input pipe 30 with tube connector 40, and is communicated with input pipe 30 by tube connector 40 by this internal pipeline 501.
In the present embodiment, the external diameter of distributor 50 is consistent with the internal diameter of header 10, and this distributor 50 engages with header 10, and is soldered on header 10, thus seals the other end of this header 10.Three chambers 102 make detailed description for example below:
The internal pipeline 501 of distributor 50 extends to the one end of protruding header 10, and be formed at the opening of input pipe 30 adaptation, this internal pipeline 501 also forms three pipelines from internal shunt, and one end that these three pipelines are positioned at header 10 at distributor 50 respectively forms three openings, these three openings are adaptive respectively at the tube connector 40 of correspondence, and just arranging in center the one end being arranged on distributor 50.Input pipe 30 and tube connector 40 insert corresponding opening respectively, then weld, thus input pipe 30 is communicated with the internal pipeline 501 of distributor 50 with tube connector 40.When refrigerant flows into distributor 50 from input pipe 30, undertaken shunting in rear inflow tube connector 40 by the internal pipeline 501 of distributor 50, then flow in corresponding chamber 102, finally flow into respectively flat tube 20 in chamber 102 and carry out heat exchange.
By arranging distributor 50 by the coolant distribution in input pipe 30 in each tube connector 40 in the present embodiment, thus make the cold medium flux that flows in each chamber 102 basically identical, and then it is basically identical to make to flow into cold medium flux in each flat tube 20.
With reference to the structural representation that Fig. 3, Fig. 3 are coolant distribution device second embodiment of the present invention.In the present embodiment, a diffluence room 103 also can be set in header 10 and shunt.Such as, one end of header 10 and the other end are equipped with the blanking cover for sealing this header 10, the distribution plate 60 with this header 10 adaptation is also provided with in its pipe, there is between the blanking cover of this distribution plate 60 and header 10 other end diffluence room 103, and tube connector 40 is all communicated with diffluence room 103 with input pipe 30.
In the present embodiment, the external diameter of distribution plate 60 is consistent with the internal diameter of header 10, this distribution plate 60 can engage with header 10, and separate this header 10 with the dividing plate 101 near header 10 other end, form above-mentioned chamber 102, separate this header 10 with the blanking cover of header 10 other end, form above-mentioned diffluence room 103.It should be noted that in the present embodiment, diffluence room 103 does not arrange flat tube 20.
During work, first the refrigerant of input pipe 30 flows in diffluence room 103, then branched to by diffluence room 103 in each tube connector 40 be communicated with this diffluence room 103, and flowed in corresponding chamber 102 by tube connector 40, finally flow in flat tube 20 and carry out heat exchange.Therefore the coolant distribution device that provides of the present embodiment, achieves the flow flowing into refrigerant in each chamber 102 basically identical, thus improves the heat exchange efficiency of flat tube 20.
Further, the internal diameter that tube connector 40 is positioned at one end of chamber 102 is less than the internal diameter of its other end.In the present embodiment, because the length of tube connector 40 is different, cause the resistance of each tube connector 40 different, therefore can according to the internal diameter size of length adjustment tube connector 40 other end of tube connector 40, thus make the resistance of each tube connector 40 consistent.Particularly, the internal diameter of tube connector 40 other end of each chamber 102 correspondence is consistent, and the internal diameter of one end increases relative to the distance of input pipe 30 with chamber 102 and evenly increases.Thus ensure that refrigerant is consistent by the flow flowing into refrigerant in each chamber 102 after shunting further, and then effectively can improve the heat exchange efficiency of flat tube 20 further.
The present invention also provides a kind of parallel-flow heat exchanger, and this parallel-flow heat exchanger comprises coolant distribution device, and the structure of this coolant distribution device and principle can refer to aforementioned, do not repeat them here.Owing to adopting aforementioned coolant distribution device, thus improve the heat exchange efficiency of flat tube, and then improve the performance of parallel-flow heat exchanger, be therefore more suitable for people and use.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
