d2の関係が成立する異径管とされているのである。The evaporator heat exchanger of the present embodiment also has substantially the same structure as that of the first embodiment, but in the case of the present embodiment, the outlet side at the connection portion of the heat transfer tube 1 is used as the flow dividing pipe 4 than the other portions. A different diameter tube with a small diameter is used. In addition, the diversion pipe 4
The outer diameter of the connection portion of the heat transfer tube 1 with the heat transfer tube 1 is
The diameter is increased so as to be the same as the inner diameter of the. That is,
The flow dividing pipe 4 in the present embodiment is an inlet side pipe line 4a connected to the flow divider 2 side, and a heat transfer pipe 1 continuous with the inlet side pipe line 4a.
A radially enlarged conduit 4b to which the connection site of the enlarged-diameter tube passage 4b are made of the outlet conduit 4c, the inlet inner diameter d 1 and the radially enlarged tube path side conduit 4a inside diameter d 2 and an outlet Between the inner diameter d 3 of the side pipe 4c and d 3 <d 1 <

伝熱管１により拘束されているため、振動発生には至ら
ない。In the case of the present embodiment, since the different-diameter pipe having the above-described structure is used as the diversion pipe 4, due to the influence of the expanded flow loss in the expanded pipe line 4b and the contraction loss in the outlet side pipe line 4c, Since ΔP 0 in equation (1) becomes large, in order to maintain the pressure loss ΔP in the diversion pipe 4 at a predetermined value,
Inlet side conduit compared to the case of using a branch pipe with uniform diameter
The inner diameter d 1 of 4a can be increased. This inlet side pipeline
4a is the part where vibration easily occurs, but the inner diameter of the part
When d 1 is increased, the flow velocity of the flowing refrigerant is reduced. Therefore, the vibration of the flow dividing pipe 4 is suppressed, and the generation of abnormal noise in the heat exchanger is greatly reduced. In the outlet side conduit 4c of the distribution pipe 4, the refrigerant flow velocity is remarkably increased, but vibration is not generated because the portion is restricted by the heat transfer pipe 1.
本実施例では、分流管と伝熱管との接続部位を拡径管路
としているが、該拡径管路は必ずしも必要ではない。In the present embodiment, the connecting portion between the flow dividing pipe and the heat transfer pipe is used as the expanded diameter pipe, but the expanded diameter pipe is not always necessary.
