Fig. 3 is the cross-sectional schematic according to the planar structure of the knockout of the utility model.
The specific embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Shown in Fig. 1 to 3; According to a kind of knockout of the utility model, comprise cylindrical shell 11 and be separately positioned on the following end-plate 12 of cylindrical shell 11 lower ends and the last end-plate 13 of upper end; Cylindrical shell 11 is with following end-plate 12 and go up the airtight inner chamber 20 of end-plate 13 formation; Following end-plate 12 is provided with the feed tube 30 with inner chamber 20 conductings, evenly is provided with many separating tubes 40 with inner chamber 20 conductings on the last end-plate 13, is provided with an inner cap 50 that covers the port of export of feed tube 30 in the inner chamber 20; The internal diameter of inner cap 50 evenly is provided with a plurality of equal liquid holes 51 greater than feed tube 30 internal diameters on the sidewall of inner cap 50.The high speed refrigerant gets into inner cap 50 from feed tube 30; And in inner cap 50, produce eddy current, and the gas-liquid two-phase cold-producing medium is fully mixed, a plurality of equal liquid holes 51 evenly are set on the sidewall of inner cap 50; Cold-producing medium at a high speed gets into inner chamber 20 from equal liquid hole 51; Make cold-producing medium in inner chamber 20, produce eddy current once more, the gas-liquid two-phase cold-producing medium is further fully mixed, flow into equably in each separating tube 40.
Equal liquid hole 51 requires to be regular shape; As be circular hole or rectangular opening; Process smooth no burr etc., the gross area of equal liquid hole 51 is between the 40%-50% of cross-sectional area of feed tube 30, makes the pressure drop in flow process of high speed refrigerant littler; The effect of refrigerant entering inner chamber 20 generation eddy current is better, thereby gas-liquid two-phase is mixed.
Preferably, the port of export of feed tube 30 is provided with the back-up ring 60 that boosts, and the back-up ring 60 that boosts embeds the endoporus of feed tube 30 and fits tightly with its inwall.After fluid is flowed through a segment distance; Owing to reasons such as pipe frictions, can make the pressure of fluid that loss is arranged, when back-up ring 60 is boosted in setting in the runner; The area in the hole owing to boost on the back-up ring 60 is less than the cross-sectional area of feed tube 30; Thereby the refrigerant pressure drop is reduced, and speed raises, and helps in inner cap 50, producing eddy current after refrigerant flow rate raises the gas-liquid two-phase cold-producing medium is fully mixed.More preferably, the endoporus area of the back-up ring 60 that boosts is that refrigerant speedup effect is better between the 50%-60% of cross-sectional area of feed tube 30.
During work, after the refrigerant in the feed tube 30 passes through the back-up ring 60 that boosts, because the cross section sudden contraction; Produce for the first time that pressure increases, promptly reduce the pressure loss in the liquid flow process, when flow of liquid behind a segment distance; Pressure has loss, therefore changes pressure through the back-up ring 60 that boosts, and making it produce pressure increases; Near original pressure, the speed of refrigerant raises, and refrigerant flow rate increases back generation eddy current in inner cap 50 fully mixes the gas-liquid two-phase cold-producing medium; For two phase refrigerants are mixed fully, through equal liquid hole 51 secondary boosters on the inner cap 50, a nearly step is near original pressure of fluid; Make refrigerant approach the pressure of feed tube 30 at the pressure of separating tube 40; Cold-producing medium at a high speed produces eddy current once more after getting into inner chamber 20, mix making the gas-liquid two-phase cold-producing medium fully mix like this through twice eddy current, thereby flow into equably in each separating tube 40.
The utility model also provides a kind of Air-Cooled Heat Pump Unit, comprises aforesaid knockout, and Air-Cooled Heat Pump Unit in the course of the work; The knockout of application of aforementioned makes refrigerant be evenly distributed to a plurality of separating tubes 40 from feed tube 30, and then evenly flows into a plurality of finned evaporators, and this knockout can significantly improve the separatory situation of heat exchanger; Make the coolant quantity of each fin even, the fin heat exchange is abundant, and frosting is even; Increase the exchange capability of heat of unit, the unit efficiency is increased.
From above description, can find out that the utility model the above embodiments have realized following technique effect:
According to the knockout of the utility model and have its Air-Cooled Heat Pump Unit, through boost back-up ring with in the equal liquid hole that covers refrigerant is boosted for twice, increase flow velocity; In inner cap and inner chamber, produce eddy current, gas-liquid two-phase is fully mixed, be evenly distributed in each separating tube; Thereby significantly improve the separatory situation of heat exchanger, make the coolant quantity of each fin even, the fin heat exchange is abundant; Frosting is even, increases the exchange capability of heat of unit, and the unit efficiency is increased.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
