Title
(EN) MICROCHANNEL HEAT EXCHANGER WITH VARYING FIN DENSITY
(FR) ÉCHANGEUR DE CHALEUR À MICROCANAUX À DENSITÉ D'AILETTE VARIABLE
Abstract
(EN)
A heat exchanger (100) of a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a plurality of microchannel tubes (104, 106), where each microchannel tube (104, 106) of the plurality of microchannel tubes (104, 106) is configured to direct refrigerant therethrough, and a plurality of fin sets (116), where each fin set (116) of the plurality of fin sets (116) is disposed between corresponding adjacent microchannel tubes (104, 106) of the plurality of microchannel tubes (104, 106). Additionally, each fin set (116) of the plurality of fin sets (116) includes a respective fin density based on a location of the respective fin set (116) along a height (112) of the heat exchanger (100).

Cette invention concerne un échangeur de chaleur (100) d'un système de chauffage, de ventilation, de climatisation et de réfrigération (CVC&R), comprenant une pluralité de tubes à microcanaux (104, 106), chaque tube à microcanaux (104, 106) de la pluralité de tubes à microcanaux (104, 106) étant configuré pour diriger du fluide frigorigène à travers celui-ci, et une pluralité d'ensembles d'ailettes (116), chaque ensemble d'ailettes (116) de la pluralité d'ensembles d'ailettes (116) étant disposé entre des tubes à microcanaux adjacents correspondants (104, 106) de la pluralité de tubes à microcanaux (104, 106). De plus, chaque ensemble d'ailettes (116) de la pluralité d'ensembles d'ailettes (116) comprend une densité d'ailette respective sur la base d'un emplacement de l'ensemble d'ailettes respectif (116) le long d'une hauteur (112) de l'échangeur de chaleur (100).
