Abstract (en)
[origin: EP2913616A1] A heat exchanger includes: a heat exchange body through which a fluid serving as a cooled object passes; and a coolant passage which is provided in at least one of a central portion and an outer circumferential portion of the heat exchange body, and through which a coolant exchanging heat with the heat exchange body flows, wherein the heat exchange body includes: a first heat transfer means which extends from a central portion to an outer circumferential portion; and a second heat transfer means which extends in a circumferential direction, and which intersects the first heat transfer means, a heat transfer efficiency of the first heat transfer means is greater than that of the second heat transfer means. It is thus possible to effectively transfer heat to the coolant passage provided in the outer circumferential portion or the central portion, and the good heat conductive property is ensured in the heat exchanger, which enables the improvement of the cool efficiency.
