Abstract
The utility model relates to a capillary structure which is fixed on a hard tube. The capillary has the same direction with the hard tube. The capillary and the hard tube are packed by a piece of tin foil paper. A galvanized steel tube is adopted to displace aluminum tubes, thus reducing a manufacturing cost and conserving resource. The strength of the steel tube is largely greater than that of the aluminum tubes, therefore the anti-vibration capability of an evaporator can be enhanced and the tin foil paper can prevent radiation so as to prevent excessive rising of the temperature of the refrigerant in the capillary.
Description
Technical field
The utility model relates to a kind of capillary mounting structure.
Background technology
Capillary is a most frequently used throttle mechanism in domestic refrigerator, household freezer, room air conditioner and the small commercial equipment.What the restricting element of household electric refrigerator was used is capillary, and its internal diameter is 0.6-2.5mm, and length is generally 2-4m, and capillary is to reduce refrigerant flow by its length pressure is reduced.Capillary between liquid pipe and evaporimeter, during compressor operating, the refrigerant amount that the refrigerant flow that capillary is controlled is vaporized in can just compensating evaporator, capillary is reduced to evaporating pressure with refrigerant liquid from high pressure.
Summary of the invention
The purpose of this utility model provides low, the easy for installation radiation-resistant capillary of a kind of cost.
Its technical problem that solves the utility model adopts the ground technical scheme to be: a kind of capillary, and wherein, described capillary is fixed on the stereoplasm tube, and capillary is identical with the direction of stereoplasm tube, and with the tin thin paper capillary and stereoplasm tube is coated.The tin thin paper can completely cut off radiation, prevents because changing ahead of time of the cooling substance in the capillary that the temperature difference causes reduced the refrigeration of refrigerator.
Stereoplasm tube is a coating steel pipe, and coating steel pipe is bent into the S shape.Adopt coating steel pipe to replace aluminum pipe, reduced manufacturing cost, saved resource; The intensity of steel pipe is far longer than aluminum pipe, has increased the shock resistance of evaporimeter, and is convenient to install.
Stereoplasm tube and ultra-thin aluminium sheet are in aggregates by bonding, sulfuration, overlay film and compacting.The aluminium sheet area reaches, and compares heat exchange effect with steel pipe and obviously improves, and can save energy 18% than threaded pipe type.
The beneficial effects of the utility model are: adopt coating steel pipe to replace aluminum pipe, reduced manufacturing cost, saved resource; The intensity of steel pipe is far longer than aluminum pipe, has increased the shock resistance of evaporimeter, compares with the threaded pipe type structure, and S shape evaporimeter is made simple, and is easy for installation, can change flexibly according to the refrigeration plant shape; The area of aluminium sheet is big, improves heat exchange effect; The tin thin paper can radiation proof, prevents that the temperature of refrigerant inside capillary from raising too fast.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model;
Among the figure: 1, coating steel pipe, 2, the tin thin paper, 3, capillary, 4, aluminium sheet
The specific embodiment
