Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2014/091747
Kind Code:
A1
Abstract:
In this heat exchanger, a tank section (73) that forms three tank spaces (73a-73c) disposed along the direction of flow of external air is formed from: a plate header (731) to which a coolant tube (16a) and a cooling water tube (43a) are joined; a tank header (732) that forms the tank spaces inside; and a partition plate (734) and intermediate plate (733) that configure interconnecting pathways (733a, 733b) that interconnect each tube and each tank space. The center interconnecting pathway (733b) that interconnects the cooling water tube (43a) and the center tank space (73c) disposed in the center along the direction (X) of flow of external air is formed by providing a through hole having a shape extending from the cooling water tube (43a) towards the center tank space (73c) side at the intermediate plate (733). As a result, it is possible to easily form fluid ducts formed in the tank section in a heat exchanger configured in a manner so as to be able to exchange heat between three types of fluid.
