HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2013/190617

Kind Code:

A1

Abstract:

Provided is a heat exchanger that is capable of evenly distributing fluid to a plurality of flow paths across a wide range of fluid flow rate states. The heat exchanger comprises: a flow path formation section (51) having a plurality of aligned fluid flow paths; a distribution path formation section (53) having a distribution path (57) to which each of the entry ports (55) for the plurality of fluid flow paths is connected; and a cylindrical partition wall (59) that is provided inside the distribution path formation section, that has the distribution path positioned on the outside of the outer peripheral side thereof, and that demarcates an introduction path (63) on the inner side thereof. The cylindrical partition wall has a plurality of distribution holes (65), and when the flow path cross-sectional area of the introduction path is represented by S, the flow path diameter of the introduction path is represented by d, the sum total of the areas (σ) of the plurality of distribution holes is represented by Σσ, the alignment length of the plurality of distribution holes is represented by L, and the diameter of the distribution holes is represented by d', the following is satisfied: L/d' × π(d/2)^2 > Σσ ≥ 2S.
