Description
Technical field
The utility model relates to air-conditioning technical field, specifically is a kind of cooling medium distributor of air-conditioner.
Background technology
At present, in the large power air-conditioned device that adopts fin-tube heat exchanger, heat exchanger generally adopts the form of multi-channel parallel, to guarantee in the heat exchanger tube enough flow velocitys being arranged, reaches heat exchange effect preferably, guarantees that simultaneously the pressure drop of heat exchanger limits within the specific limits.Can give play to higher performance for making fin-tube heat exchanger, must guarantee as far as possible to enter each heat-exchanger circuit (fin-tube heat exchanger inside is provided with a plurality of heat-exchanger circuits) coolant quantity evenly, otherwise will cause some heat-exchanger circuit refrigerant very few, the waste heat exchange area, and some loop refrigerant is too much even outlet band liquid, the safety of harm compressor.
For the coolant quantity that guarantees to enter each heat-exchanger circuit evenly, the mode that generally adopts is now: refrigerant is after throttling, the cooling medium distributor that before advancing fin-tube heat exchanger, adds an air-conditioner, that is to say, the flowing through channel of refrigerant is first throttling, enter the cooling medium distributor of air-conditioner then, enter again in each heat-exchanger circuit of fin-tube heat exchanger.
The cooling medium distributor of described air-conditioner generally comprises coolant distributor and (promptly divides road, funnel-form, have a plurality of tap holes on minute road, the quantity of this tap hole is consistent with quantity capillaceous) with the capillary that is used to be connected heat-exchanger circuit and coolant distributor (the quantity unanimity of the heat-exchanger circuit of quantity capillaceous and fin-tube heat exchanger inside).
The cooling medium distributor of described air-conditioner is effective for the small-power air-conditioner, but, because the heat-exchanger circuit quantity of the fin-tube heat exchanger that large power air-conditioned device adopted (generally is at least 20 greatly, that have or even 40), tap hole and quantity capillaceous corresponding to coolant distributor just becomes bigger so, if just finish the distribution of refrigerant with a coolant distributor, then the tap hole on the coolant distributor needs dozens of, can bring two problems like this: one, coolant distributor must be done greatlyyer, used raw material are just many, coolant distributor can not be done very greatly again, this minute road consumption is few simultaneously, and the hot die tool is expensive, so the production cost of coolant distributor is higher, and, in order on coolant distributor, to make more tap hole, the distance between the tap hole is diminished, tap hole is crowded, thereby cause processing difficulties, increased production cost; Two, number of capillaries is big, increased production cost on the one hand, on the other hand when connecting capillary and coolant distributor, concrete performance difficulty, that is to say, in with the corresponding tap hole welding process on every capillary and the coolant distributor, the welding difficulty, yield rate is low, and this is because the quantity of soldering opening is big, and will guarantee that the temperature of each soldering opening will reach requirement simultaneously, reach requirement with regard to difficult simultaneously with the temperature that guarantees each soldering opening like this, welding quality will be do not influenced and temperature reaches requirement,, integral body will be influenced as long as there is a soldering opening not weld, this has just increased difficulty to actual production, be difficult for welding successfully, increased production cost simultaneously, reduced production efficiency.
The utility model content
The technical problems to be solved in the utility model is, a kind of cooling medium distributor that can greatly reduce production costs, enhance productivity under the uniform prerequisite of the coolant quantity that guarantees to enter each heat-exchanger circuit and specifically implement to be easy to air-conditioner is provided.
The technical solution of the utility model is, the cooling medium distributor of the utility model air-conditioner, it comprises coolant distributor and a plurality of capillary, have a plurality of tap holes on the described coolant distributor, described capillary is corresponding one by one with tap hole, and described inlet capillaceous connects with the outlet of corresponding tap hole, and it also comprises a plurality of threeways, this threeway is corresponding one by one with capillary, the inlet of described threeway and corresponding outlet connection capillaceous; Described threeway is provided with two and is used for the outlet that is connected with the inlet of heat-exchanger circuit, and the outlet of described threeway is corresponding one by one with heat-exchanger circuit.
After adopting said structure, the utility model compared with prior art, have the following advantages: the utility model has adopted threeway, so compared with prior art, corresponding to the fin-tube heat exchanger of same size, can guarantee on the one hand to enter each heat-exchanger circuit coolant quantity evenly, on the other hand, the quantity of the tap hole on the coolant distributor of the present utility model just can reduce half, makes the processing coolant distributor simple, has reduced the quantity capillaceous that connects usefulness simultaneously.Because the quantity of the tap hole on the coolant distributor greatly reduces, so the hot die tool of producing material that coolant distributor consumed, process time and developing for production is all greatly saved, reduced production cost, improved production efficiency, simultaneously, for tap hole enough adjustment spaces have just been arranged, distance between the tap hole just can be done suitably greatly, with convenient welding, thereby makes processing simple, reduce production cost, improved production efficiency.In sum, the utlity model has and under the uniform prerequisite of the coolant quantity that guarantees to enter each heat-exchanger circuit, greatly to reduce production costs, to enhance productivity and specifically implement to be easy to advantage.
