摘要： PROBLEM TO BE SOLVED: To obtain a heat exchanger provided with tanks for collecting and distributing fluid at the opposite ends of a tube in which abnormal noise based on breakup or deformation of bubble is reduced. SOLUTION: A regulation pipe 17 extends from an inlet pipe 15 into a tank 13 and a passage 172 in the regulation pipe 17 communicates with the tank 13 through many holes 171 made in the regulation pipe 17. When fluid flows through the passage 172, it flows sequentially into the inlet tank 13 through the hole 171 and since the flow rate decreases gradually toward the forward end side of flow A, current velocity of fluid decreases gradually in the passage 172. Generation of sound wave is suppressed by making gentle the variation of current velocity thereby reducing breakup or deformation of bubble.

摘要： PROBLEM TO BE SOLVED: To improve working efficiency in an inspection process when the inspection of sealing property and gas quantity distribution of a rotary door is performed. SOLUTION: By mounting a door lever 25 on a rotary shaft 21 of a rotary door 13 and transmitting operating force to the door lever 25 via a control cable when an occupant performs a manual operation for a blowout mode switching lever, a blowout mode can be switched by rotating the rotary door 13 integrally with the door lever 25. The door lever 15 is provided with a projection part 25b at a tip. On a surface of a heater case, a plurality of positioning marks 10a corresponding to each blowout mode are provided. Therefore, the positioning of the door lever 25 can be performed to the blowout mode corresponding to the positioning mark 10a by aligning the projection part 25b to the positioning mark 10a.
