Abstract
A silencer for eliminating the noise generated by high-pressure spray of refrigerant via capillary into evaporator in refrigerating systems is composed of capillary, evaporator pipe and silencing tube whose one end is welded to evaporator pipe and whose another end is connected to capillary after reduced in diameter and welded. Its advantages include high effect and low cost.
Description
The present invention relates to the silencing apparatus that refrigeration systems such as a kind of refrigerator, refrigerator-freezer are used.
In the refrigeration systems such as existing refrigerator, refrigerator-freezer, the high voltage terminal refrigeration agent sprays into low voltage terminal evaporator tube (2) through capillary tube (1) throttling high pressure, in production in enormous quantities, be connected with evaporator tube (2) in order to ensure capillary tube (1) that weldering does not take place is stifled, capillary tube (1) stretches in the evaporator tube (2) must one section cantilever segment (4), forms vortex (5) on every side at this cantilever segment (4) during work.In addition in production in enormous quantities, capillary tube (1) mouth of pipe is sheared to add and is difficult to guarantee mouth of pipe rounding, no burr man-hour, after being welded, capillary tube (1) and evaporator tube (2) can not guarantee the concentricity of cantilever segment (4) Yu the evaporator tube (2) of capillary tube (1), when refrigeration agent sprays into evaporator tube (2) at a high speed, cantilever segment (4) vibrates, vortex (5) causes liquid hammer to produce whistler, and causes that vaporizer resonance produces noise.
The objective of the invention is to design and a kind ofly can eliminate refrigeration agent in the refrigeration systems such as refrigerator, refrigerator-freezer produces noise when the capillary tube high pressure sprays into vaporizer silencing apparatus.
Design proposal of the present invention: this silencing apparatus is made of capillary tube (1), evaporator tube (2) and hush tube (3), hush tube (3) one ends and evaporator tube (2) welding, and the other end reducing and expansion have bell-mouthed capillary tube (1) welding.
The present invention compared with prior art, the one because capillary tube horn mouth outer wall has good face with hush tube reducing inwall and contacts, solderless is blocked up in the time of guaranteeing to produce in enormous quantities; The 2nd, because capillary tube horn mouth rounding, natural transition is good, no burr, and no cantilever segment, friction produces the position, and no eddy current forms the district, and no liquid hammer produces, and does not therefore have whistler and produces, and the problem that vaporizer resonance produces noise has also obtained solution.In addition, the present invention not only can eliminate noise, and simple in structure, and cost is low, is particularly suitable for producing in enormous quantities.
Fig. 1 is a structure sectional view of the present invention.
Fig. 2 is a prior art structure sectional view.
1 a kind of embodiment of the present invention is described in conjunction with the accompanying drawings.At first by prior art manufacturing hush tube (3), and with hush tube (3) one end reducings, then capillary tube (1) is inserted behind the necking end and with its mouth of pipe and expand into horn mouth (6), and make horn mouth (6) outer wall have good face to contact with hush tube (3) reducing inwall, again with necking end end and the welding of capillary tube (1) outer wall, the other end of hush tube (3) inserts in the evaporator tube (2), and the present invention can be finished in evaporator tube (2) end and the welding of hush tube (3) outer wall.
Claims (1)
1, a kind of silencing apparatus, comprise capillary tube (1), evaporator tube (2), it is characterized in that: between capillary tube (1) and evaporator tube (2), a hush tube (3) is set, hush tube (3) one ends and evaporator tube (2) welding, the other end reducing and expansion have bell-mouthed capillary tube (1) welding.
