Refrigerant branching structure in header {Micro Channel Heat Exchanger}
[11] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a header for uniformly distributing refrigerant in a microchannel heat exchanger. In general, a heat exchanger is used for an air conditioner of a cooler and a heater that raises or reduces a room temperature.
[12] 1 is a perspective view briefly showing the appearance of a conventional heat exchanger, Figure 2 is an exploded view showing the coupling relationship of the components of the conventional heat exchanger.
[13] Referring to these drawings, the refrigerant branching structure in the header according to the prior art is a refrigerant formed in the horizontal header (1, 2) and the horizontal header (1, 2) through which the refrigerant flows and flows in the horizontal header. In the heat exchanger consisting of a plurality of vertical refrigerant pipes, that is, the tube 3 and the fin (5) attached to the tube (3) for distributing the gas, a plurality of refrigerant distribution holes (4a) through which the refrigerant passes at a predetermined position And a refrigerant distribution pipe 4 for supplying refrigerant to the header is inserted into one side of the header. That is, the refrigerant introduced through the refrigerant distribution pipe 4 is distributed through a plurality of refrigerant distribution holes 4a provided at a predetermined position of the refrigerant distribution pipe 4, and the refrigerant thus distributed is the refrigerant distribution hole. It flows along the channel 3a of the tube 3 lying adjacent to 4a.
[14] However, in the header structure according to the related art, since a separate pipe having a refrigerant distribution hole must be inserted into the header in order to distribute the refrigerant, not only the workability is lowered but also the manufacturing cost increases.
[15] The present invention has been made in view of the above problems, and has an object of simplifying the manufacturing process of the microchannel heat exchanger and reducing the manufacturing cost of the microchannel heat exchanger.

[2] Figure 2 is an exploded view showing the coupling relationship of the components of a conventional heat exchanger.
[3] Figure 3 is a perspective view briefly showing the appearance of the heat exchanger according to the present invention.
[4] Fig. 4A is a perspective view showing a part of the header in Fig. 3 cut away;

[16] The refrigerant branching structure in the header according to the present invention includes: a horizontal header in which a hollow is formed and through which a refrigerant flows; A plurality of vertical refrigerant pipes inserted into the horizontal headers for distributing refrigerant flowing in the horizontal headers; A heat exchanger consisting of fins attached between the vertical refrigerant pipes, the heat exchanger comprising: a partition wall installed in the header in a length direction and having a plurality of holes through which refrigerant passes at a predetermined position; It characterized in that it comprises a refrigerant distribution pipe for supplying a refrigerant to one side of the header.
[17] Hereinafter, a preferred embodiment of the refrigerant branching structure in the header according to the present invention will be described with reference to the accompanying drawings.
[18] 3 is a perspective view briefly showing the external appearance of the heat exchanger according to the present invention, Figure 4a is a perspective view showing a part of the header in FIG.
[19] Referring to these drawings, the header 1 is characterized by having a plurality of holes through which the refrigerant passes in the longitudinal direction, that is, the partition wall 1b having the refrigerant distribution holes 1c. A partition 1b is formed in a longitudinal direction at a substantially central portion of the header 1 for supplying the refrigerant to the tube 3, and the refrigerant is supplied to the tube 3 at a predetermined position of the partition 1b. A refrigerant distribution hole 1c for evenly distributing the refrigerant in 1) is provided.
[20] Therefore, in the refrigerant branching structure in the header according to the present invention, the refrigerant supplied to the header 1 is distributed by the refrigerant distribution hole 1c provided in the partition wall 1b and adjacent to the refrigerant distribution hole 1c. It is supplied to the tube 3 to flow.
[21] 4B is a cross-sectional view illustrating the brazed header in FIG. 4A.
[22] Referring to Figure 4b, it is preferable that the partition wall 1b according to the present invention is made in one piece with the header 1, in particular by a brazing method.
[23] That is, the partition wall 1b is integrated with the header, and bends the plate-shaped material into a 'G' shape, and the bending material is abutted by the brazing method. Will be connected / bonded.
[24] Therefore, the refrigerant branching structure in the header according to the present invention does not need to insert the refrigerant distribution pipe having the refrigerant distribution hole 4a into the header 1 in order to distribute the refrigerant evenly to the tube 3.
[25] The refrigerant branching structure in the header according to the present invention has the effect of simplifying the processing method of the header, thereby simplifying the manufacturing process and reducing the manufacturing cost.
[26] Another effect according to the present invention is to maximize the efficiency of the heat exchanger by allowing the refrigerant to flow uniformly in the heat exchanger.
