Title
(EN) FLAT TUBE AND HEAT EXCHANGER
(FR) TUBE PLAT ET ÉCHANGEUR DE CHALEUR
(ZH) 扁管及换热器
Abstract
(EN)
The present application provides a flat tube and a heat exchanger. The flat tube comprises a middle tube segment and narrowed opening connection segments located at two ends of the middle tube segment, the width of the narrowed opening connection segments being less than the width of the middle tube segment, a transition connection segment being provided between each narrowed opening connection segment and the middle tube segment, and a fastening and positioning part being provided on the transition connection segment. As the transition connection segment of the flat tube in the present application is provided with a fastening and positioning part, the fastening and positioning part has the effect of local reinforcement, ensuring that the joint position of an end portion of the flat tube and a manifold slot can withstand a high pressure, satisfying the pressure resistance requirement for a heat exchanger in the refrigeration industry.

La présente invention concerne un tube plat et un échangeur de chaleur. Le tube plat comprend un segment de tube central et des segments de raccordement à ouverture rétrécie situés au niveau de deux extrémités du segment de tube central, la largeur des segments de raccordement à ouverture rétrécie étant inférieure à la largeur du segment de tube central, un segment de raccordement de transition étant prévu entre chaque segment de raccordement à ouverture rétrécie et le segment de tube central, et une partie de fixation et de positionnement étant disposée sur le segment de raccordement de transition. Lorsque le segment de raccordement de transition du tube plat dans la présente invention est pourvu d'une partie de fixation et de positionnement, la partie de fixation et de positionnement a l'effet d'un renforcement local, assurant que la position d'articulation d'une partie d'extrémité du tube plat et d'une fente de collecteur peut résister à une pression élevée, satisfaisant l'exigence de résistance à la pression pour un échangeur de chaleur dans l'industrie de la réfrigération.
