         11 . The structure of  claim 9 , wherein the top portion is disposed in proximity to a fan of the refrigerant circuit. 
     
     
         12 . The structure of  claim 11 , wherein at least one of the first diameter, the second diameter and a gradient of curve of the sidewalls is based on at least one of fan dimensions or a fan type. 
     
     
         13 . The structure of  claim 9 , further comprising one or more support rods connected between the sidewalls and a bottom surface of a housing of the refrigerant circuit, wherein the support rods are configured to prevent the sidewalls from collapsing. 
     
     
         14 . A structure comprising:
 a body having a hollow body interior portion, wherein the body comprises a bottom portion, a top portion, and sidewalls connecting the bottom portion and the top portion, wherein a first diameter of the bottom portion is greater than a second diameter of the top portion, and wherein the sidewalls have a curved shape bended inwards towards the hollow body interior portion;   an inlet configured to intake air into the hollow body interior portion;   a channel configured to channelize the air from the inlet towards the top portion;   an outlet configured to output air from the hollow body interior portion; and   one or more support rods connected between the sidewalls and an external surface on which the structure is placed, wherein the support rods are configured to prevent the sidewalls from collapsing.   
     
     
         15 . A unit comprising:
 a housing comprising a plurality of vents;   a fan disposed in proximity to a top wall of the housing, wherein the fan is configured to draw air from ambient environment towards a housing interior portion via the plurality of vents; and   a structure disposed in the housing interior portion, wherein the structure comprises:
 a body having a hollow body interior portion, wherein:
 the body comprises a bottom portion, a top portion and sidewalls connecting the bottom portion and the top portion, 
 a first diameter of the bottom portion is greater than a second diameter of the top portion, and 
 the sidewalls have a curved shape bended inwards towards the hollow body interior portion; 
 
 an inlet configured to intake air into the hollow body interior portion; and
