Document Type and Number:
Japanese Patent JP2019207085
Kind Code:
A
Abstract:
To provide a heat exchanger which uniformizes distribution of flow quantities of a fluid circulating in the heat exchanger and achieves high heat exchange efficiency.SOLUTION: A heat exchanger 100 includes: multiple tubes 10 in which intake air (a first fluid) circulates; multiple lamination passage parts 25 to 29 which are respectively formed between the laminated tubes 10 and in which a coolant (a second fluid) circulates; a supply passage part 23 to which the coolant is supplied; and a distribution passage part 24 which distributes the coolant supplied to the supply passage part 23 into the lamination passage parts 25 to 29. In a lamination direction (a Y axis direction) of the tubes 10, a passage width L3 of the lamination passage part 27 at the nearest position to the supply passage part 23 is smaller than passage widths L1, L2, L4, L5 of the other lamination passage parts 25, 26, 28, 29.SELECTED DRAWING: Figure 3
