Capillary leak-proof distributor

Abstract

The invention discloses a capillary leak-proof distributor, wherein a plurality of capillary connecting jacks for connecting a capillary tube are formed at one end of a main body; a refrigerant pipe connecting jack for connecting a refrigerant pipe is formed at the other end of the main body; a plurality of the capillary connecting jacks form a plurality of channels inside the main body; the other ends of a plurality of the channels are gathered at the refrigerant pipe connecting jack so that a plurality of the capillary connecting jacks are mutually communicated with the refrigerant pipe connecting jack; and a frustum groove is arranged along the axle center of the main body at one end of the main body at the capillary connecting jacks. The capillary leak-proof distributor has simple structure; the frustum groove is arranged along the axle center of the main body at one end of the main body at the capillary connecting jacks so that the periphery of the capillary connecting jacks is evenly heated and the capillary tube is evenly and firmly welded on the capillary connecting jacks, thus avoiding the problem of refrigerant leakage due to non-uniform welding and improving the service life.

Description

technical field [0001] The present invention relates to a leak-proof dispenser. In particular, it relates to an anti-leakage distributor for capillary tubes, which is evenly heated at the sockets connected with copper tubes and does not cause poor welding due to uneven temperature. Background technique [0002] Generally speaking, the working process of an air conditioner is as follows: the compressor compresses the gaseous refrigerant into a high-temperature / high-pressure refrigerant; the gaseous refrigerant compressed into a high-temperature / high-pressure state is cooled in the condenser; The refrigerant in the evaporator is converted into a low-temperature / low-pressure refrigerant; in the evaporator, through heat exchange, it absorbs the heat around the evaporator, thereby reducing the temperature of the surrounding air. [0003] Air conditioners can be divided into: integrated air conditioners installed on windows, etc., which integrally constitute cooling and heat remo...

Problems solved by technology

[0010] However, if figure 2 , image 3 As shown, half of each capillary connection socket 6 on the above-mentioned capillary distributor is adjacent to the peripheral wall of the capillary distributor, and the thickness of the wall is relatively thin, and the other half is adjacent to the axial center of the capillary distributor, and the thickness of the wall is relatively thin. thick, thus causing the overall wall thickness of the capillary connection socket 6 to be uneven

In this way, when the capillary is welded, due to the uneven wall thickness of the capillary connection socket 6, the heating is uneven, and the welding failure often occurs, resulting in leakage of the refrigerant.
