Title:
HEAT EXCHANGER AND REFRIGERATION DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/074346
Kind Code:
A1
Abstract:
In the present invention, a fluid collision part (17) is provided on the first fluid flowpath (11) side of a connecting flowpath (10b) that connects the inlet-side header flowpath (10) and the first fluid flowpath (11), and a multi-branched flowpath (10c) is provided so as to guide, to the first fluid flowpath (11) group, fluid that has collided with the fluid collision part (17) and is dispersed as a result. As a result of this configuration, refrigerant from the connecting flowpath (10b) of the inlet-side header flowpath (10) collides with the fluid collision part (17) and is dispersed, flowing from the multi-branched flowpath (10c) to the first fluid flowpath (11) group, and is distributed uniformly to each of the first fluid flowpaths (11), thereby improving heat exchanging efficiency and making it possible to provide a compact, high-thermal-efficiency heat exchanger.
