Abstract
The utility model discloses a throttling and liquid distributing device of an air conditioner. The throttling and liquid distributing device comprises a liquid distributing device and a plurality of short throttling tubes. The liquid distributing device comprises a main liquid inlet channel and a plurality of branch liquid outlet channels communicated with the main liquid inlet channel, and the short throttling tubes are respectively fixed into the corresponding branch liquid outlet channels. The throttling and liquid distributing device has the advantages that the throttling and liquid distributing device is simple in structure and compact in appearance, and functions of throttling, pressure reduction and liquid distributing are integrated; the throttling and liquid distributing device is impact-resistant and vibration-resistant, and a comprehensive uniform liquid distributing effect can be realized.
Description
Technical field
The utility model relates to air-conditioning and manufactures field, specifically a kind of throttling knockout of air-conditioning.
Background technology
, the air-conditioning such as peculiar to vessel or industrial for the moving vehicle such as plate armour, shelter, its composite request to parts is more and more higher, progressively to future developments such as succinct, efficient, reliable, high accuracy.For example, when evaporimeter divides way many, general air-conditioning is uneven owing to distributing, cause evaporimeter heat exchange area utilization rate not enough, the series of problems such as complete machine Energy Efficiency Ratio reduction, in some high-intensity oscillation occasions, often there is the faults such as capillary fracture, expansion valve inefficacy, also have a strong impact on the overall performance of air-conditioning simultaneously.
General capillary tube for air conditioner, heating power expansion valve or electric expansion valve are as reducing pressure by regulating flow element, and knockout is dispensed to evaporimeter by the cold-producing medium after reducing pressure by regulating flow by a required minute way.Because the cold-producing medium after reducing pressure by regulating flow is vapour-liquid two-phase mixture, be generally the flow pattern of bubble flow or Yong Sailiu, and be subject to gravity etc. to affect easy generation vapor-liquid separation phenomenon, thus the uniformity that impact distributes.Along with air-conditioning constantly application and popularization in special dimension, for example armoring car air-conditioner adopts R134a cold-producing medium at present mostly in addition, though space is little, refrigeration capacity is larger, generally adopts 6-12 road knockout, causes and distributes inequality, and disengagement area is under-utilized; Because structure is limited, add the wind field inequality that evaporation fan brings, the heat exchange inhomogeneities of having aggravated evaporimeter, thereby the decline that brings cold and efficiency simultaneously.Aspect reducing pressure by regulating flow element, capillary, heating power expansion valve or electric expansion valve easily produce the faults such as cracking, fracture under high-intensity oscillation.Can improve the vibration resistance of reducing pressure by regulating flow element, the uniformity of knockout becomes problem anxious to be resolved.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of throttling knockout of air-conditioning, adopts the mode of reducing pressure by regulating flow after first separatory, and during separatory, cold-producing medium is pure high-pressure liquid, can not produce vapour-liquid two-phase mixture, and shunting uniformity is improved.
The technical solution of the utility model is:
A throttling knockout for air-conditioning, includes knockout and a plurality of restriction sleeve, and described knockout includes minute tapping channel that main liquid inlet channel and a plurality of and main liquid inlet channel are communicated with, and described a plurality of restriction sleeves are individually fixed in corresponding minute tapping channel.
The port of export of each described restriction sleeve is all connected with distributing pipe, and the inlet end of each distributing pipe is deep in corresponding minute tapping channel and connects with corresponding restriction sleeve, and the internal diameter of distributing pipe is greater than the internal diameter of restriction sleeve.
Described restriction sleeve length and internal diameter are than being 5-20.
Within described minute, a tapping channel is shoulder hole structure, and the aperture of the feed liquor end that it is connected with main liquid inlet channel is less than the aperture of fluid end and is greater than the internal diameter of restriction sleeve, and described restriction sleeve is fixed in fluid end and its entrance point and cascaded surface offset closes.
Described restriction sleeve external diameter is the structure that slight interference coordinates with a minute tapping channel for knockout.
The end of described restriction sleeve inner ring is provided with inner ring chamfering.
Advantage of the present utility model:
(1), the utility model adopts the mode of reducing pressure by regulating flow after first separatory, during separatory, cold-producing medium is pure high-pressure liquid, can not produce vapour-liquid two-phase mixture, shunting uniformity is improved;
(2), reducing pressure by regulating flow element of the present utility model selects restriction sleeve, it is installed on knockout inside, structure is more stable, has more shock resistance, vibration requirement;
(3), restriction sleeve of the present utility model adopts stepped hole and distributing pipe to carry out two ends and fixes, and guaranteed the stability of restriction sleeve location;
(4), restriction sleeve of the present utility model is that slight interference coordinates with a minute tapping channel, the entrance point of restriction sleeve and cascaded surface offset and close, and have guaranteed that liquid the problem of interior leakage can not occur within dividing tapping channel;
(5) aperture of the feed liquor end that, the internal diameter of distributing pipe of the present utility model is connected with main liquid inlet channel with minute tapping channel is all greater than the internal diameter of restriction sleeve, the inner ring chamfering of the utility model restriction sleeve inner ring end has the effect of buffering, liquid flow is impacted less.
The utility model is simple in structure, moulding is light and handy, integrates throttling, step-down and separatory, can realize shock resistance, vibration, can realize again separatory comprehensive effect more uniformly.

The specific embodiment
See Fig. 1, Fig. 2, a kind of throttling knockout of air-conditioning, includes knockout 1 and eight restriction sleeves 2, and the port of export of each restriction sleeve 2 is all connected with corresponding distributing pipe 3, restriction sleeve 2 length and internal diameter are than being 5-20, and the end of restriction sleeve 2 inner rings is provided with inner ring chamfering 21(and sees Fig. 3), knockout 1 includes minute tapping channel 12 that main liquid inlet channel 11 and a plurality of and main liquid inlet channel 11 are communicated with, feed tube 4 extend in main liquid inlet channel 11, dividing tapping channel 12 is shoulder hole structure, the aperture of the feed liquor end that minute tapping channel 12 is connected with main liquid inlet channel 11 is less than the aperture of fluid end and is greater than the internal diameter of restriction sleeve 2, restriction sleeve 2 is fixed in fluid end and its entrance point and cascaded surface offset closes, the inlet end of each distributing pipe 3 is deep in corresponding minute tapping channel 12 and the entrance point of each distributing pipe 3 and the connection of the port of export of corresponding restriction sleeve 2, the internal diameter of distributing pipe 3 is greater than the internal diameter of restriction sleeve 2, the structure that the external diameter of restriction sleeve 2 coordinates for slight interference with minute tapping channel 12 of knockout 1.
