Embodiment 1

[0032] Such as image 3 , Figure 4 and Figure 5 As shown, the refrigerant distributor for heat exchangers of the present invention includes: a distributor body 11, a refrigerant pipe 15, and a homogenizing component 20; the distributor body 11 is in the shape of a hollow cylinder, with a refrigerant inlet 12 formed at one end, and One end is closed to form a bottom surface with several through holes 13; the refrigerant pipes are respectively inserted into the interior of the distributor body through the through holes; the homogenization component 20 is arranged on the distributor body 11 along the length direction of the distributor body 11 internal central location.

[0033] The homogenizing component 20 includes: a disc-shaped fixed plate 21 and a guide post 22; the disc-shaped fixed plate 21 is fixed on the inner wall of the bottom surface of the body 11 formed with the through hole 13, and the fixed plate 21 An annular through-groove 21 a that can be inserted into the...

Embodiment 2

[0036] Such as Figure 6 As shown, the guide column 122 is in the shape of a cylinder, and several refrigerant pipe guide grooves 123 are formed on its outer peripheral surface along the length direction.

Embodiment 3

[0038] Such as Figure 7 As shown, the guide post 222 is in the shape of a truncated cone, and its diameter gradually increases along the direction from the inlet 12 to the through hole 13 .

Abstract

The invention discloses a kind of secondary refrigerant allotter using in heat exchanger and its assembly method. It comprises allotter body, secondary refrigerant pipe, and uniformization component. The allotter body appears hollow cylindrical form; its one end is formed to secondary refrigerant inflow entrance, the other end is hermetically formed to bottom surface with many interpenetrating hole. The secondary refrigerant pipe is cut into the inner of the allotter by the interpenetration hole. The uniformization component is set at the inner center position of the allotter body along the direction of the length of the allotter body. The uniformization component includes disk shape fixed plate and diversion column. The disk shape fixed plate is fixed on the inner wall of the end of the allotter formed interpenetrating hole. The fixed plate is formed ring interpenetration groove in which the interpenetration hole is cut. One end of the diversion column is fixed at the center of the fixed plate, and the other end is pointed to the inflow entrance. Its advantage is that the assembly technique is simple; the secondary refrigerant is guided uniformly and swimmingly to each secondary refrigerant pipe; and the noise caused by bumpy flow can be reduced furthest.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a refrigerant distributor for the heat exchanger and an assembly method thereof. Background technique [0002] Generally speaking, household appliances such as air conditioners and refrigerators realize their cooling or heating functions by generating cold or warm air through heat exchangers. Several refrigerant pipes for conveying refrigerant are formed on the heat exchanger and attached to the refrigerant. Several cooling fins of the tube, and each refrigerant tube of the heat exchanger are connected with a refrigerant distributor, and the refrigerant is received through the refrigerant distributor. [0003] Such as figure 1 and figure 2 As shown, the structure of the existing refrigerant distributor of the heat exchanger is as follows: one end of the main body of the distributor body 1 having a cylindrical shape is formed with a refrigerant inlet 2, and the other end is formed with sever...
