PROBLEM TO BE SOLVED: To provide a condenser capable of restricting re-gasification of liquid phase refrigerant separated into gas and liquid at a liquid receiving part.SOLUTION: A condenser of this invention comprises a plurality of metallic heat exchanging pipes 5 and a pair of metallic header tanks 6 arranged at both sides in a longitudinal direction of the heat exchanging pipes 5 under a state in which the longitudinal direction is directed in the vertical direction and connected to both ends of the heat exchanging pipes 5. The condenser 1 is provided with a condensing part 2 and a liquid receiving part 4 for receiving refrigerant having flowed out of the condensing part 2 and separating it into gas and liquid. A hollow body 11 is installed in one of the header tanks 6 and there are provided a refrigerant flow-in part 13 into which the refrigerant having passed through the condensing part 2 flows and the liquid receiving part 4. A heat conduction restricting wall 14 made of a material of which thermal conductivity is lower than a metal forming the head tanks 6, is arranged between the refrigerant flow-in part 13 and the liquid receiving part 4. The heat conduction restricting wall 14 is provided with a flow-in side communicating part 44 to cause the refrigerant in the refrigerant flow-in part 13 to flow into the liquid receiving part 4.SELECTED DRAWING: Figure 3
【課題】受液部において気液に分離された液相冷媒の再気化を抑制しうるコンデンサを提供する。【解決手段】コンデンサは、複数の金属製熱交換管5と、長手方向を上下方向に向けた状態で熱交換管5の長手方向の両側に配置されかつ熱交換管5の両端部が接続された1対の金属製ヘッダタンク6とを備えている。コンデンサ1に、凝縮部2と、凝縮部2から流出した冷媒を受け入れて気液に分離する受液部4とを設ける。一方のヘッダタンク6内に中空体11を配置することによって、凝縮部2を通過した冷媒が流入する冷媒流入部13と、受液部4とを設ける。冷媒流入部13と受液部4との間に、ヘッダタンク6を形成する金属よりも熱伝導率が低い材料からなる熱伝導抑制壁14を設ける。熱伝導抑制壁14に、冷媒流入部13内の冷媒を受液部4内に流入させる流入側連通部44を設ける。【選択図】図3
