HEAT EXCHANGER AND TURBULENT FLOW GENERATING INSERT

PROBLEM TO BE SOLVED: To reduce a risk of ebullition of refrigerant at a heat exchanger.SOLUTION: The second flowing duct for use in flowing the second media 7 acting as refrigerant is extended among pipes 2 and a housing 6. Turbulent flow generating inserts 10 having ducts 11 including a side wall 12 through which the second media 7 can flow are arranged between the pipes 2 in the second flowing duct. There is provided at least one partition wall duct 14 having a closed side wall 15 for every turbulent flow generating inserts 10. At least one longitudinal end part of the partition wall duct 14 is spaced apart from the housing 6. In at least one partition wall duct 14, both ends in the longitudinal direction are opened and the second media may pass there under a state in which the duct is arranged in the housing 6. The partition wall duct 14 is manufactured by a compression process and there are provided a raised first side surface 23 and the second side surface 24 folded below the first side surface 23.SELECTED DRAWING: Figure 1 【課題】熱交換器において、冷媒沸騰のリスクを低減する。【解決手段】冷媒である第２の媒体７のための第２の流通ダクトを管２と筐体６との間に延在させる。第２の媒体７が連通可能な側壁１２を有するダクト１１を備える乱流生成インサート１０を第２の流通ダクト内において管２同士の間に配置する。閉鎖した側壁１５を有する、少なくとも１つの隔壁ダクト１４を乱流生成インサート１０ごとに設ける。隔壁ダクト１４の少なくとも長手方向端部の１つを筐体６から離間させる。少なくとも１つの隔壁ダクト１４において、長手方向の両端部を開口し、筐体６内に配設された状態において、第２の媒体が通過するようにする。隔壁ダクト１４を圧縮プロセスにより製造し、立ち上がった第１の側面２３と第１の側面２３の下に折り畳まれた第２の側面２４を設ける。【選択図】図１
