Abstract
The utility model discloses a blowing expansion evaporator and a direct cooling refrigerator which are designed to solve the problem of large noise of the existing refrigerator with the blowing expansion evaporator.The blowing expansion evaporator comprises a blowing expansion evaporator plate, a capillary tube and a gas return tube, and further comprises a transition tube, wherein one end of the transition tube is connected with the capillary tube; the other end of the transition tube is connected into an inlet tube of the blowing expansion evaporator plate; the capillary tube is arranged in the gas return tube in a penetrating manner; the gas return tube is connected with the blowing expansion evaporator plate; and the diameter of the transition tube is greater than that of the capillary tube.The capillary tube is 1.8mm in diameter, and the transition tube is 3mm in diameter.The transition tube is a copper tube.The direct cooling refrigerator comprises the blowing expansion evaporator.The blowing expansion evaporator effectively reduces ejection sound of a refrigerant at the tail end of the capillary tube due to sudden reducing, reduces a level of noise of the whole refrigerator, and is applicable to various direct cooling refrigerators.The direct cooling refrigerator is low in noise and keeps a good refrigerating effect.
Description
Technical field
The utility model relates to a kind of direct cooling refrigerator that propels the price of formula evaporimeter that propels the price of formula evaporimeter and this is installed.
Background technology
Refrigerator is a kind of conventional household electrical appliances, the freshness date that can extend food.
The formula that the propels the price of evaporimeter of refrigerator is directly assemblied in box house, its conventional manufacture craft is that requirement propels the price of plate upper pipeline import department and dwindles gradually with capillary and be directly connected, then crimping fixed capillary and sealing pipeline, and need to guarantee that capillary import impression spacing together with crimping place is finally greater than 10mm.Said structure causes capillary and propels the price of pipeline gap larger, although meet the refrigeration demand of refrigeration system, fails to consider the injection noise of the cold-producing medium of refrigerator under use state.
The GB of noise of refrigerator requires to be less than 45 decibels, and is equipped with its complete machine noise of refrigerator that propels the price of formula evaporimeter substantially 44 decibels of left and right, just reaches the noise level limit requirement of sufficient national standard to refrigerator.Noise has greatly become the main dissatisfied point that is equipped with the refrigerator that propels the price of formula evaporimeter, and cannot effectively solve after sale the noise problem that propels the price of formula evaporimeter.
Utility model content
An object of the present utility model is the formula that the propels the price of evaporimeter that proposes a kind of effective reduction complete machine level of noise.
Another object of the present utility model is to propose the good formula that the propels the price of evaporimeter of a kind of refrigeration.
Another object of the present utility model is to propose the low direct cooling refrigerator of a kind of complete machine level of noise.
For reaching this object, on the one hand, the utility model by the following technical solutions:
One propels the price of formula evaporimeter, comprises and propels the price of evaporator plate, capillary and muffler, and described evaporimeter also comprises transition conduit; One end of described transition conduit connects described capillary, and the other end is connected in the inlet tube that propels the price of evaporator plate; Described capillary is located in described muffler, described muffler with described in propel the price of evaporator plate and be connected, the diameter of described transition conduit is greater than described diameter capillaceous.
Particularly, described diameter capillaceous is 1.8mm, and the diameter of described transition conduit is 3mm.
Particularly, described transition conduit is copper pipe.
Particularly, described muffler with described in propel the price of evaporator plate and be connected by argon arc welding.
Particularly, described middle part capillaceous passes described muffler, and is wrapped on the outer wall of described muffler.
On the other hand, the utility model is by the following technical solutions:
A kind of direct cooling refrigerator, described refrigerator comprises the above-mentioned formula that propels the price of evaporimeter.
The utility model propels the price of formula evaporimeter at capillary and propels the price of transition conduit is set between evaporator plate, utilize transition conduit reducing to make cold-producing medium and slowly discharge after pressure energy accesses transition when through capillary end, effectively reduce capillary end cold-producing medium due to the injection sound that reducing sends suddenly, thereby reduce the complete machine level of noise of refrigerator.
The utility model direct cooling refrigerator has adopted the above-mentioned formula evaporimeter that propels the price of, and noise is low, and it is good that refrigeration keeps.
Accompanying drawing explanation
Fig. 1 is the utility model preferred embodiment one structural representation.
In figure, be labeled as:
1, propel the price of evaporator plate; 2, transition conduit; 3, capillary; 4, muffler.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Preferred embodiment one:
As shown in Figure 1, this preferred embodiment provides one to propel the price of formula evaporimeter.This propels the price of formula evaporimeter and forms by propelling the price of evaporator plate 1, transition conduit 2, capillary 3 and muffler 4.Diameter is that the capillary 3 of 1.8mm adopts the copper pipe of diameter 3mm to come transition crimping in the junction of evaporation pipeline, transition conduit 2 is inserted in the inlet tube that propels the price of evaporator plate 1 and is carried out crimping, and then capillary 3 is passed in evaporimeter muffler 4, last muffler 4 carries out argon arc welding with the exit of propelling the price of evaporator plate 1 and is connected.
Cold-producing medium, after capillary 3 step-downs, muffler 4 backheat coolings, utilizes and increases transition conduit 2 reducings, makes cold-producing medium pressure energy when through capillary 3 end access transition and slowly discharges.Effectively reduce capillary 3 end cold-producing mediums due to injection that suddenly reducing sends " " sound, thereby reduce the complete machine level of noise of refrigerator.
This preferred embodiment propels the price of formula evaporimeter and adopts new structure, needn't change and effectively reduce noise in the assembling mode on refrigerator.In the time of noise test, to test effect improved obviously, complete machine level of noise reduces by 4 decibels, substantially reaches the complete machine noise level of pipe-coil type evaporator direct cooling refrigerator and wire-and-tube evaporator direct cooling refrigerator.
Preferred embodiment two:
This preferred embodiment provides one to propel the price of formula evaporimeter, and its structure and preferred embodiment one are basic identical.This propels the price of formula evaporimeter and comprises and propel the price of evaporator plate, capillary, transition conduit and muffler.Capillary is connected with transition conduit, and transition conduit is connected in the inlet tube that propels the price of evaporator plate; Capillary is located in muffler, muffler with propel the price of evaporator plate and be connected, the diameter of transition conduit is greater than diameter capillaceous.
Difference is: the concrete diameter of capillary and transition conduit is not limit, and transition conduit can realize capillary and propel the price of the direct transition of evaporator plate and be connected; The material of transition conduit is not limit, muffler with propel the price of the concrete connected mode of evaporator plate and do not limit.
Preferred embodiment three:
A kind of direct cooling refrigerator, refrigerator comprises the formula that the propels the price of evaporimeter as described in preferred embodiment one or two.
