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 reduce abnormal sound based on the break up or deformation of bubbles upon flowing of liquid into an outlet pipe. SOLUTION: A heat exchanger, in which tanks 13, 14 for assembling and distributing liquid are arranged at both ends of tubes 11, through the inside of which the liquid flows, and an outlet pipe 16 is connected to the outlet tank 14, is equipped with bubble guiding pipes 17, 22 for guiding bubbles in the liquid, which are taken into at the side of the inlet tank 13, to the downstream side in the flow of liquid of the opening 161 of the outlet tank 14 side in the outlet pipe 16. According to this method, the bubbles in the liquid are conducted to flow while bypassing the opening 161 of the outlet pipe 16 whereby the break up or deformation of the bubbles in the liquid inflow part of the outlet pipe 16, which becomes the cause of generation of big sound especially, can be avoided thereby permitting the suppression of generation of abnormal sound.

摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger 1 capable of preventing air accumulation in a tank 5, and reducing a size of the tank 5. SOLUTION: The heat exchanger 1 includes two inlet/outlet pipes connected to a side surface of the tank 5. A shape of the tank 5 is changed from a conventional rectangular solid shape into a stepped shape which one side is high, and the other side is low in a longitudinal direction of a capsule 7 of the tank 5, and a center position of a connecting part 44 on an inlet side of the inlet/ outlet pipe of a side cap 9 is shifted to a slanting upper direction from a center position of a connecting part 45 on an outlet side. Thereby, a width of the tank 5 does not become extremely large to a width of a tube 3. As a result, the size of the tank 5 can be reduced, and a mounting space of the heat exchanger 1 is sufficiently secured. Furthermore, because a separator 8 of an approximately dog leg shape is provided in the tank 5, the air accumulation in a tank chamber 12 on an inlet side and a tank chamber 13 on an outlet side of the tank 5 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a heating heat exchanger, e.g. a heater core, in which routing of cooling water piping can be facilitated by taking out first and second inlet pipes and an outlet pipe from same direction while suppressing increase of dead space, e.g. dimensional increase a top capsule in the height direction, as much as possible. SOLUTION: A car air conditioner comprises an air conditioning unit where the air conditioning zones of left and right seats in a cabin can be subjected to independent temperature control, and a heating heat exchanger 5, e.g. a heater core, disposed in the air conditioning unit. The heating heat exchanger 5 can take out first and second inlet pipes 17, 18 and an outlet pipe 19 not from the depth direction of a top capsule 23 but from the side wall at one end thereof in the breadthwise direction, i.e., from same circumferential direction of the top capsule 23.

摘要： PROBLEM TO BE SOLVED: To prevent deformation of a mounting flange 42 provided to an upper tank 4A.SOLUTION: A heat exchanger 3 is provided with a mounting flange 42 around an upper tank 4A. At a corner part of the mounting flange 42, a fastening part 43 is formed. The mounting flange 42 has a tank side seal surface opposed to a case side seal surface 20a of a cooler case 2, a rib wall 44 folded back orthogonally to the tank side seal surface from a circumferential edge of the tank side seal surface is provided on the entire circumference of the tank side seal surface, and a height difference corresponding to a level difference of a case side is set between the tank side seal surface and the fastening part 43 via the rib wall 44. Namely. a level difference is provided between the tank side seal surface 42a and the fastening part 43 by a height portion of the rib wall 44. With this configuration, strength of the mounting flange 42 is increased, so that deformation of the mounting flange 42 can be suppressed when supercharging pressure is applied to the inside of the cooler case 2.
