Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2011/101910
Kind Code:
A1
Abstract:
Provided is a heat exchanger having an excellent flowability of a heat medium, which can substantially uniformly circulate a heat medium in heat exchange tubes while reducing the size and the weight of a tank portion and thus the reduction of the size and the weight of the entirety of the heat exchanger. In the heat exchanger, tank portions are provided on the heat medium inlet side and the heat medium outlet side; a plurality of heat exchange tubes arranged in parallel communicate with the tank portions; an inlet-side pipe joint to be connected to an external pipe is connected to an end portion of the heat medium inlet side tank portion in the longitudinal direction; and an outlet-side pipe joint to be connected to an external pipe is connected to an end portion of the heat medium outlet side tank portion in the longitudinal direction. An expanded portion expanding outward is provided at the center portion, in the tank width direction, in the pipe joint connected portion of at least one tank portion.
