Abstract
A heat exchanger exhibiting excellent heat exchange efficiency has a heat exchange part including a group of heat supply pipes, through which a heat supply medium flows, and a heat recovery pipe part, through which a heat recovery medium flows, surrounding the heat supply pipes. Each heat supply pipe has a vertically elongated cross section and a predetermined width. The heat supply pipes are arranged so that the heat supply pipe having cross-sectional area is located farther from the center of the heat exchange part. Spacings between the heat supply pipes and an inner wall are made stepwise narrower in the direction from the center to the periphery of the heat exchange part.
Claims17
A heat exchanger having a heat exchange part comprising heat supply medium channel formed of at least one heat supply passage and heat recovery medium channel surrounding the heat supply medium channel,
- in which heat exchange part a heat supply medium passing through the heat supply medium channel exchanges heat with a heat recovery medium passing through the heat recovery medium channel;
- wherein pressure loss in the heat recovery medium channel is adjusted corresponding to an amount of heat transferred from the heat supply medium to the heat recovery medium, by configuration of a cross-sectional area of the heat recovery medium channel.
