Hvacr enclosure having offset staggered extruded louvers

Abstract

This disclosure relates generally to enclosures for HVACR units, particularly enclosures having a plurality of openings allowing airflow through the enclosure. The openings are arrayed with one column or row offset from the adjacent column or row by distances of 10-40% or 60-90% of a length of an opening. The openings may have a major axis in a vertical direction, and columns of openings are offset from one another. The distance that columns or rows are offset from one another may be at or about 30% or 70% of a length of an opening along its major axis. The openings may be extruded openings. The enclosure may be part of an HVACR unit including a spine-fin heat exchanger.

1 . A heating, ventilation, air conditioning, and refrigeration (HVACR) unit enclosure, comprising:
 a surface; and   a plurality of louvers disposed on the surface,   wherein the plurality of louvers are arranged in an array and wherein adjacent louvers are asymmetrically offset from one another in at least one direction.   
     
     
         2 . The HVACR unit enclosure according to  claim 1 , wherein the plurality of louvers are oriented in a vertical direction of the HVACR unit enclosure, and wherein a first column of the plurality of louvers is vertically offset from a second column of the plurality of louvers, the second column of the plurality of louvers adjacent to the first column of the plurality of louvers. 
     
     
         3 . The HVACR unit enclosure of  claim 2 , wherein each of the plurality of louvers has a length along a major axis, and the first column and the second column are offset from one another by between at or about 10% and at or about 40% of the length. 
     
     
         4 . The HVACR unit enclosure of  claim 2 , wherein each of the plurality of louvers has a length along a major axis, and the first column and the second column are offset from one another by between at or about 60% and at or about 90% of the length. 
     
     
         5 . The HVACR unit enclosure of  claim 2 , wherein each of the plurality of louvers has a length along a major axis, and the first column and the second column are offset from one another by between at or about 10% and at or about 30% of the length. 
     
     
         6 . The HVACR unit enclosure of  claim 2 , wherein each of the plurality of louvers has a length along a major axis, and the first column and the second column are offset from one another by between at or about 70% and at or about 90% of the length. 
     
     
         7 . The HVACR unit enclosure of  claim 2 , wherein each of the plurality of louvers has a length along a major axis, and the first column and the second column are offset from one another by at or about 30% of the length or by at or about 70% of the length. 
     
     
         8 . The HVACR unit enclosure of  claim 2 , wherein the first column and the second column each include between 10 and 16 louvers. 
     
     
         9 . The HVACR unit enclosure of  claim 1 , wherein each of the plurality of louvers includes:
 a radiused section defining an opening at the surface of the HVACR unit enclosure; and   a section extending towards an inside of the HVACR unit enclosure from the radiused section.   
     
     
         10 . The HVACR unit enclosure of claim  16 , wherein an angle between the section extending towards the inside of the HVACR unit enclosure and the surface of the HVACR unit enclosure is at or about 80 degrees. 
     
     
         11 . An HVACR unit, comprising:
 the HVACR unit enclosure of  claim 1 ; and   a spine-fin heat exchanger located within the HVACR unit enclosure.   
     
     
         12 . An HVACR unit, comprising:
 the HVACR unit enclosure of  claim 2 ; and   a spine-fin heat exchanger located within the HVACR unit enclosure.
