Abstract
A heat exchanger includes a conduit configured to flow a refrigerant therethrough and a fin coupled to the conduit. The fin has a slot formed therethrough, in which the slot has a first portion and a second portion continuous with the first portion and disposed at an angle relative to the first portion.
Claims24
A heat exchanger, comprising:
- a conduit configured to flow a refrigerant therethrough;
- and
- a fin coupled to the conduit, wherein the fin has an opening formed therethrough, the opening having a first portion extending along the fin in a first direction and a second portion different from the first portion and extending along the fin in a second direction crosswise to the first direction, wherein the first portion and the second portion are continuous with one another, the first portion has a first length, the second portion has a second length, and the first length and the second length are different from one another.
A heat exchanger, comprising:
- a first heat exchanger slab including a plurality of first fins, wherein each first fin of the plurality of first fins has a plurality of first protrusions forming a plurality of first openings through the first fin, each first protrusion of the plurality of first protrusions having a first portion and a second portion continuous with the first portion, wherein the first portion overlaps the corresponding first opening and extends in a first direction along the corresponding first fin, and the second portion overlaps the corresponding first opening and extends in a second direction along the corresponding first fin at a first angle relative to the first direction;
- and
- a second heat exchanger slab including a plurality of second fins, wherein each second fin of the plurality of second fins has a plurality of second protrusions forming a plurality of second openings through the second fin, each second protrusion of the plurality of second protrusions having a third portion and a fourth portion continuous with the third portion, wherein the third portion overlaps the corresponding second opening and extends in a third direction along the corresponding second fin, and the fourth portion overlaps the corresponding second opening and extends in a fourth direction along the corresponding second fin at a second angle relative to the third direction.
A heat exchanger, comprising:
- a conduit configured to flow a working fluid therethrough;
- a fin coupled to the conduit and including an array of punch-throughs;
- each punch-through of the array of punch-throughs forming an opening extending through the fin and a protrusion extending from an edge of the opening;
- a first portion of the opening of each punch-through of the array of punch-throughs having a first trajectory that is substantially in alignment with an airflow path through the heat exchanger;
- a second portion of the opening of each punch-through of the array of punch-throughs being continuous with the first portion and having a second trajectory that is different than the first trajectory;
- a third portion of the protrusion of each punch-through of the array of punch-throughs extending along the first trajectory of the first portion of the corresponding opening;
- and
- a fourth portion of the protrusion of each punch-through of the array of punch-throughs extending along the second trajectory of the second portion of the corresponding opening.
