The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in seeing figures.1.and.2, Fig. 1 is the structural representation of the utility model coolant distribution device the first embodiment, and Fig. 2 is the structural representation of distributor among Fig. 1.The coolant distribution device that present embodiment provides comprises header 10, the flat tube 20 that is communicated with this header 10 and is used for the input pipe 30 of input refrigerant, be provided with at least one dividing plate 101 in the header 10 this header 10 is separated to form some chambers 102, each chamber 102 all is communicated with some flat tubes 20, and each chamber 102 is communicated with input pipe 30 by tube connector 40 respectively.
In the present embodiment, above-mentioned each chamber 102 interior all one by one correspondence one tube connector 40 is set, and this tube connector 40 runs through dividing plate 101 and is communicated with input pipe 30.
The utility model is separated to form some chambers 102 by dividing plate 101 is set with this header 10, and at each chamber 102 interior tube connector 40 that arrange, this tube connector 40 is communicated with input pipe 30.Thereby when refrigerant flow to input pipe 30 place, thereby at input pipe 30 and tube connector 40 punishment streams, so that flow into respectively corresponding chamber by tube connector 40 behind the coolant distribution, then flow into and carry out heat exchange in the flat tube 20.Because before flowing into header 10, by the coolant distribution in 40 pairs of input pipes of tube connector 30, therefore can be so that flow into the cold medium flux of each chamber 102 and substantially be consistent, can be so that flow into the flow of refrigerant in each flat tube 20 and substantially be consistent, thereby improved the heat exchange efficiency of flat tube 20, and then improved the heat exchange efficiency of heat exchanger.
Should be noted that in the present embodiment that the distance between the quantity of aforementioned barriers 101 and the adjacent separator 101 can arrange according to actual needs, does not do further restriction at this.In preferred present embodiment, the distance between adjacent two dividing plates 101 equates, and the quantity of each chamber 102 corresponding plaque pipe 20 equates.
Particularly, above-mentioned input pipe 30 can all be connected with a distributor 50 with tube connector 40, thus with the coolant distribution in the input pipe to each tube connector 40, and flow in the corresponding chamber 102 by tube connector 40.For example, one end of header 10 is provided with the blanking cover for this end of sealing, the other end is provided with and the adaptive distributor 50 of header 10 and the other end of this distributor 50 these headers 10 of sealing, this distributor 50 has the internal pipeline 501 that is communicated with tube connector 40 and input pipe 30, and by this internal pipeline 501 tube connector 40 and input pipe 30 is communicated with.
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 the header 10, thereby seals the other end of this header 10.Below three chambers 102 make detailed description for example:
The internal pipeline 501 of distributor 50 extends to an end that protrudes header 10, and be formed at the adaptive opening of input pipe 30, this internal pipeline 501 also internally shunting forms three pipelines, and these three pipelines are positioned at respectively three openings of end formation of header 10 at distributor 50, these three openings are adaptive respectively at the tube connector 40 of correspondence, and are the center and just are being listed as an end that is arranged on distributor 50.Input pipe 30 and tube connector 40 insert respectively corresponding opening, then weld, thereby so that input pipe 30 and tube connector 40 be communicated with the internal pipeline 501 of distributor 50.When refrigerant flows into distributor 50 from input pipe 30, shunt in the rear inflow tube connector 40 by the internal pipeline 501 of distributor 50, then flow in the corresponding chamber 102, carry out heat exchange the flat tube 20 from chamber 102 interior inflows respectively at last.
In the present embodiment by arrange distributor 50 with the coolant distribution in the input pipe 30 to each tube connector 40, thereby so that the cold medium flux that flows in each chamber 102 is basically identical, and then to flow into each flat tube 20 interior cold medium flux basically identical.
With reference to Fig. 3, Fig. 3 is the structural representation of the utility model coolant distribution device the second embodiment.In the present embodiment, also can shunt in the header 10 interior diffluence room 103 that arrange.For example, one end of header 10 and the other end are equipped with the blanking cover for this header 10 of sealing, also be provided with the distribution plate 60 adaptive with this header 10 in its pipe, have a diffluence room 103 between the blanking cover of this distribution plate 60 and header 10 other ends, and tube connector 40 and input pipe 30 are communicated with diffluence room 103 all.
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 these headers 10 with the dividing plate 101 near header 10 other ends, form above-mentioned chamber 102, separate this header 10 with the blanking cover of header 10 other ends, form above-mentioned diffluence room 103.Should be noted that diffluence room 103 does not arrange flat tube 20 in the present embodiment.
During work, the refrigerant of input pipe 30 at first flows in the diffluence room 103, then branch in each tube connector 40 that is communicated with this diffluence room 103 by diffluence room 103, and flow in the corresponding chamber 102 by tube connector 40, flow at last and carry out heat exchange in the flat tube 20.Therefore the coolant distribution device that provides of present embodiment, the flow of having realized flowing into each chamber 102 interior refrigerant is basically identical, thereby has improved the heat exchange efficiency of flat tube 20.
Further, tube connector 40 is positioned at the internal diameter of an end of chamber 102 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 be according to the internal diameter size of length adjustment tube connector 40 other ends of tube connector 40, thus so that the resistance of each tube connector 40 is consistent.Particularly, the internal diameter of tube connector 40 other ends of each chamber 102 correspondence is consistent, and the internal diameter of an end increases and evenly increases with the distance of chamber 102 with respect to input pipe 30.Thereby guarantee that further refrigerant is consistent by the flow of shunting each chamber 102 interior refrigerant of rear inflow, and then the further heat exchange efficiency of Effective Raise flat tube 20.
The utility model also provides a kind of parallel-flow heat exchanger, and this parallel-flow heat exchanger comprises the coolant distribution device, and the structure of this coolant distribution device and principle can with reference to aforementioned, not repeat them here.Owing to adopt aforementioned coolant distribution device, thereby improved the heat exchange efficiency of flat tube, and then improved the performance of parallel-flow heat exchanger, therefore more be suitable for people and use.
It below only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
