HEAT EXCHANGER AND REFRIGERATION CYCLE APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18247236 titled 'HEAT EXCHANGER AND REFRIGERATION CYCLE APPARATUS
Simplified Explanation
The patent application describes a heat exchanger design that includes a fin and a heat transfer tube.
- The fin extends in a widthwise direction and a longitudinal direction, and the heat transfer tube passes through the fin.
- The fin consists of a planar portion and multiple first and second protruding portions.
- The first protruding portions are curved downward in the longitudinal direction, while the second protruding portions are curved upward.
- Each second protruding portion surrounds a through hole in the fin.
- The vertices of the first and second protrusions are located at the same position in the widthwise direction.
Original Abstract Submitted
A heat exchanger includes: a fin extending in a widthwise direction along an air flow direction and extending in a longitudinal direction crossing the air flow direction; and a heat transfer tube passing through the fin. The fin includes a planar portion, and a plurality of first protruding portions and a plurality of second protruding portions that protrude from the planar portion. The plurality of first protruding portions include a first projection curved downward in the longitudinal direction, and a second projection curved upward in the longitudinal direction. Each of the plurality of second protruding portions surrounds a corresponding one of the plurality of through holes. A vertex of the first projection and a vertex of the second projection are located at the same position in the widthwise direction.
