Description

A kind of refrigeration pipe that can reduce the refrigerator noise
Technical field
The present invention relates to a kind of refrigeration plant, more particularly, is a kind of refrigeration pipe that can reduce the refrigerator noise.
Background technology
The source of refrigerator noise mainly contains two kinds, and a kind of is noise or the resonance that produces from compressor, and another kind is the noise that refrigeration pipe produces in circulating; In existing refrigerator refrigeration system, capillary is in throttling process, when cold-producing medium flows to the evaporimeter port, because the space suddenly increases, pressure reduces, make cold-producing medium discharge suddenly, speed up, and evaporation simultaneously, the gas mixture at night that flows is fast impinged upon on the evaporimeter tube wall, produce noise thus, though this noise is little to the noise effect of refrigerator, but can send the strange sound of a kind of very tiny " Zi Zilala ", cause very easily under quiet environment that people's mood is tired to make an uproar, more can influence people's sleep quality at dead of night.
In addition, the intake method of existing evaporator of refrigerator is generally: air inlet pipe and escape pipe are positioned at the bottom of evaporimeter, gas flow pattern is served as reasons down from last in the evaporimeter, refrigerating speed is slower, when causing lower floor's temperature low easily, and the upper strata temperature is still higher, and temperature reaches balance up and down needs longer a period of time, also can cause waste of electric energy to a certain extent.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of refrigeration pipe that can reduce the refrigerator noise, have the refrigerator of reduction noise, the advantage of saving electric energy.
The technical solution adopted in the present invention is as follows: a kind of refrigeration pipe that can reduce the refrigerator noise comprises coating steel pipe, the plastic, transparent flexible pipe, transition conduit, capillary, air inlet pipe, escape pipe etc., be divided into four layers, the coating steel pipe of each layer welds with steel bar, and the plastic, transparent flexible pipe is placed on the coating steel pipe of a side, air inlet pipe connects transition conduit, transition conduit connects capillary, and escape pipe and air inlet pipe all are positioned at the superiors of pipeline, and intake method is from the upper strata air inlet.
Described transition conduit is connected between capillary and the zinc-plated air inlet pipe, and its length and diameter are proportional, and the one end is placed in the zinc-plated air inlet steel pipe, and stretches into the about 12-13mm of zinc-plated air inlet steel pipe, and its other end entangles capillary.
Described capillary plays the effect of throttling, in the transition conduit socket, and an end is stretched in the transition conduit, and its internal diameter is than the approximately little 0.1~0.2mm of transition conduit internal diameter.
End reducing internal diameter that described transition conduit is connected with capillary and capillary external diameter are quite or be a bit larger tham the capillary external diameter.
The reducing internal diameter of the zinc-plated air inlet pipe at the described evaporator air inlet place that is connected with transition conduit and the external diameter of transition conduit are quite or greater than the transition conduit external diameter.
The present invention increases by one section internal diameter greater than the capillary external diameter between capillary and evaporimeter, and external diameter is less than the transition conduit of the zinc-plated air inlet pipe internal diameter in the evaporimeter, alleviated the pressure that cold-producing medium produces when entering evaporimeter, the cold-producing medium diffusion velocity is reduced, the friction that cold-producing medium and inside pipe wall are produced reduces, and then the noise of refrigerator is reduced, particularly the strange sound of " Zi Zilala " is eliminated; In addition, the mode that the present invention adopts the upper strata air inlet, gives vent to anger is after cold-producing medium enters evaporimeter by capillary, transition conduit, because the space suddenly increases, pressure reduces, cold-producing medium discharges evaporation suddenly in evaporator pipeline, can absorb heat in refrigerator simultaneously, makes the interior upper strata of refrigerator air themperature at first reduce, the reduction of temperature makes the gas on the interior upper strata of refrigerator sink, make the interior air of refrigerator form convection current, refrigerating speed is accelerated, avoided waste of electric energy.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is the partial enlarged drawing that is connected of transition conduit and capillary and coating steel pipe among Fig. 1.
Among the figure: 1, air inlet pipe, 2 transition conduit, 3 capillaries, 4 escape pipes, 5 plastic, transparent flexible pipes, 6 coating steel pipes, 7 steel bars.
The specific embodiment
Below in conjunction with accompanying drawing the present invention further is described in detail:
Referring to accompanying drawing 1, accompanying drawing 2, a kind of refrigeration pipe that can reduce the refrigerator noise, comprise coating steel pipe 6, plastic, transparent flexible pipe 5, transition conduit 2, capillary 3, air inlet pipe 1, escape pipe 4 etc., be divided into four layers, coating steel pipe 6 usefulness steel bars 7 welding of each layer, plastic, transparent flexible pipe 5 is placed on the coating steel pipe 6 of each layer side, air inlet pipe 1 connects transition conduit 2, transition conduit 2 connects capillary 3, and escape pipe 4 and air inlet pipe 1 all are positioned at the superiors of pipeline, and intake method is from the upper strata air inlet.
With reference to Fig. 2, between capillary 3 and evaporimeter, increase by one section internal diameter greater than the capillary external diameter, and external diameter is less than the transition conduit 2 of zinc-plated air inlet pipe 1 internal diameter in the evaporimeter, alleviated the pressure that cold-producing medium produces when entering evaporimeter, the cold-producing medium diffusion velocity is reduced, the friction that cold-producing medium and inside pipe wall are produced reduces, and then the noise of refrigerator is reduced, and particularly the strange sound of " Zi Zilala " is eliminated.
With reference to accompanying drawing 1, accompanying drawing 2, the mode that the present invention adopts the upper strata air inlet, gives vent to anger, after cold-producing medium enters evaporimeter by capillary 3, transition conduit 2, because the space suddenly increases, pressure reduces, and cold-producing medium discharges evaporation suddenly in evaporator pipeline, can in refrigerator, absorb heat simultaneously, make the interior upper strata of refrigerator air themperature at first reduce, the reduction of temperature makes the gas on the interior upper strata of refrigerator sink, and makes the interior air of refrigerator form convection current, refrigerating speed is accelerated, avoided waste of electric energy.
Further, described transition conduit, its length and diameter are proportional.
Further, the end reducing internal diameter that is connected with capillary of described transition conduit and capillary external diameter are quite or be a bit larger tham the capillary external diameter.
Further, the external diameter of the reducing internal diameter of the zinc-plated air inlet pipe at the described evaporator air inlet place that is connected with transition conduit and transition conduit is quite or greater than the transition conduit external diameter.
Preferably, described transition conduit stretches into the about 12-13mm of zinc-plated air inlet pipe.
Preferably, described capillary one end stretches in the transition conduit, and its external diameter of described capillary is than the approximately little 0.1~0.2mm of transition conduit internal diameter.
