Title:
INTERCOOLER
Document Type and Number:
WIPO Patent Application WO/2019/009080
Kind Code:
A1
Abstract:
This intercooler exchanges heat between supercharged intake air supercharged by a supercharger into an engine (10) and a cooling medium to cool the supercharged intake air. The intercooler is provided with a heat exchange section (200) for exchanging heat between a cooling medium flowing inside a flow passage pipe (201) and supercharged intake air flowing outside the flow passage pipe. The cooling medium includes a first cooling medium and a second cooling medium which has a temperature higher than that of the first cooling medium. The flow passage pipe has formed therein: a first cooling medium flow passage (204) through which the first cooling medium flows in a direction intersecting the direction of flow of the supercharged intake air; and a second cooling medium flow passage (205) through which the second cooling medium flows in a direction intersecting the direction of flow of the supercharged intake air. The second cooling medium flow passage is disposed upstream of the first cooling medium flow passage in the direction of flow of supercharged intake air. Fins (207) are provided inside the first cooling medium flow passage, and no fins are provided inside the second cooling medium flow passage.
