するという問題点がある。In the conventional heat exchanger as described above, the heat exchange fluid is caused to flow through the plurality of heat transfer tubes 1 connecting the headers 21A and 21B. When the fluid flows in coexistence of gas and liquid, a heat transfer tube 1 into which a large amount of liquid-phase heat exchange fluid has flowed between the heat transfer tubes 1 and a heat transfer tube 1 into which a large amount of gas-phase heat exchange fluid has flown occur. Therefore, a difference in the amount of heat exchange fluid evaporated between the heat transfer tubes 1 occurs, the amount of heat exchange in the heat exchanger fluctuates, the entire heat exchanger does not work efficiently, and the heat exchange efficiency decreases. There is a point.

It is brazed. The inner diameter of the refrigerant distribution pipe 4 is sufficiently smaller than the inner diameter of the refrigerant distribution header 5. Further, the refrigerant distribution header 5 is installed in a horizontal direction.

When the heat exchanger is used as a condenser, the low-temperature heat exchange fluid flows in a two-phase gas / liquid state inside the refrigerant distribution header 5, and as shown in FIG. In 5, the liquid phase 7 flows along the inner wall surface, and the gas phase 8 flows in the central part in a so-called annular flow mode.
Since the refrigerant distribution header 5 has a rectangular cross section, the thickness of the liquid phase 7 increases at the inner corners of the rectangular cross section.

も、液相７の熱交換流体の供給を最も受けやすくなる。Further, since the influence of gravity is added, the thickness of the liquid phase 7 at the inner corner is the largest. Since the inlet of the refrigerant distribution pipe 4 is provided at the inner corner where the thickness of the liquid phase 7 is the largest, the refrigerant distribution pipe 4 is most easily supplied with the heat exchange fluid of the liquid phase 7. That is, the header 3 connected to each refrigerant distribution pipe 4 and the heat transfer tube 1 connected to the header 3
Also, the supply of the heat exchange fluid in the liquid phase 7 is most easily received.

れて熱交換効率は向上する。The heat exchange efficiency of the heat exchanger is affected by the flow rate of the heat exchange fluid in the liquid phase 7, and if the supply of the heat exchange fluid in the liquid phase 7 cannot be obtained, the heat exchange efficiency decreases. In this way, the supply of the heat exchange fluid of the liquid phase 7 can be reliably obtained, so that the heat exchange efficiency can be improved. Further, if the diameter of the refrigerant distribution pipe 4 is further reduced to provide a certain flow path loss resistance, the heat exchange fluid is uniformly distributed, and the heat exchange efficiency is improved.

は、次式で表される。Next, the distribution state of the heat exchange fluid will be described. The pressure loss of the refrigerant is proportional to the length of the flow path and inversely proportional to the cross-sectional area of the flow path. Here, in FIG. 1, the length from the inlet of the refrigerant distribution header 5 to the first refrigerant distribution pipe 4 and the interval between the refrigerant distribution pipes 4 are respectively l 1 , the length of the refrigerant distribution pipe 4 is l 2 , and the refrigerant distribution header 4 Assuming that the flow path cross-sectional area of the refrigerant distribution pipe 5 is S 1 and the flow path cross-sectional area of the refrigerant distribution pipe 4 is S 2 , the pressure losses L 1 to L 4 from the inlet of the refrigerant distribution header 5 to the outlet of each refrigerant distribution pipe 4.
