Abstract

PURPOSE:To improve heat exchanging performance without increasing the number of parts by providing one pipe which forms both inlet header and outlet header and providing a partition in the center of the pipe and dividing the coolant route in a flat tube into an out-going section and an in-coming section. CONSTITUTION:A flat tube 10 which has no small coolant route 7 in its center is formed by bending. A connecting header 8 is connected to one end of the flat tube 10 and a header 9 which can be used for both outlet and inlet is connected to the other end. The header 9 for both outlet and inlet has its central section press-formed to divide the central section into an inlet header section 9a and an outlet header section 9b with an partition 11 and shut out the coolant. The coolant enters the pipe from the inlet header section 9a and flows the leeward side of the flat pipe 10, and the coolant, as it evaporates, enters the connecting header 8. A coolant in which the gas to liquid ratio is not uniform is mixed and uniformalized at the connecting header 8, and it flows through respective coolant routes 7 on the windward side of the flat pipe 10 and reaches the outlet header section 9b and flows out as a coolant gas with suitable super-heating. With this arrangement the gas to liquid ratio in respective coolant small routes 7 is uniformalized as much as possible to improve heat exchanging performance.

First, a flat tube 1o having a cross section without a small refrigerant passage 7 in the center portion of the tube as shown in FIG. 2 is bent and formed. A communication header 8 is connected to one end thereof, and a dual-use header 9 for entrance and exit is connected to the other end. Both the communication header 8 and the inlet/outlet header 9 are made of a brazing material whose inner and outer surfaces are clad with brazing material, and after being assembled together with the corrugated fins 2, they are integrally brazed with brazing material in a furnace.

FIG. 3 shows the joined state of the header 9 for both entrance and exit after being brazed. The clad brazing material forms a fillet 6 between the flat tube 1o and the header 9 for both entrance and exit. Furthermore, the dual-purpose header 9 for both entrance and exit is formed by compression molding at the center of the pipe, with a partition 11 protruding, and a fillet 6 is also formed near the partition to divide the refrigerant into an inlet header portion 9a and an outlet header portion 9b. It's blocked.

The fourth factor is a perspective view of another embodiment of the dual-use inlet/outlet header 9 relative to FIG. 3. FIG. 5 is an enlarged view of the disk-shaped plate material 13. One header pipe 9 is made of brazing material with brazing material clad on both the inner and outer surfaces, and has a semicircular cut groove 12 in the center, into which a disc-shaped plate 13 is fitted, as described above. As in the example, it is joined together with the corrugated fins 2 and the flat tube 1 by brazing in the furnace. As a result, the header pipe 9 is partitioned by the plate material 13 and divided into an inlet header portion 9a and an outlet header portion 9b, thereby blocking the refrigerant.

以下第1図を用いてその動作を説明する。The operation will be explained below using FIG.

The refrigerant enters from the inlet port 9a on the leeward side and flows through the leeward side 10a of the flat tube 10, and the refrigerant liquid enters the connecting header 8 while evaporating. The refrigerants flowing through each of the small refrigerant passages 7 on the leeward side 10a of the flat tube 10 and having uneven (gas)/(liquid) ratios are mixed in the communication header 8. The refrigerant (gas)/(liquid) is made uniform again, flows through each small refrigerant passage 7 on the windward side 10b of the flat tube 10, and reaches the outlet header portion 9b.

適度な過熱度を持った冷媒ガスとして流れ出る。It flows out as a refrigerant gas with a moderate degree of superheat.

In addition, in order to realize this, it is necessary to bring the inlet header 3 and the outlet header 4 to one end of the flat tube 10, and for this reason, in the conventional cassog method, the ineffective part of the 6'G1 part is As it grew larger, it became an obstacle. With this system, the inlet header 3 and the outlet header 4 can be provided with one inlet/outlet header 9.

Effects of the Invention As described above, the present invention has an inlet henge and an outlet hem.
It consists of a main tube, and by providing a partition in the center of the tube, it is possible to divide the refrigerant passage into an outgoing section and an incoming section without increasing the number of parts or requiring extra width of the flat tube. The heat exchange performance can be significantly improved.
