Heat Exchanger System and Insulation Therefor

Abstract

A heat exchanger system including a cabinet, a V-shaped round tube plate fin heat exchanger disposed within the cabinet, and an axial fan housing disposed within the cabinet and located downstream of the V-shaped round tube plate fin heat exchanger. The heat exchanger system also includes a first insulation disposed along a first portion of an inner periphery of the cabinet, a second insulation disposed along a second portion of the inner periphery of the cabinet, and a connecting member disposed along an abutment of the first insulation and the second insulation. The first portion located upstream of the V-shaped round tube plate fin heat exchanger and the second portion located downstream of the V-shaped round tube plate fin heat exchanger. A temperature of the air flowing through the second portion is less than a temperature of the air flowing through the first portion.

         7 . The heat exchanger system of  claim 6 , wherein the thickness of each of the first insulation and the second insulation is in a range of 0.55 inch to 1.25 inch. 
     
     
         8 . The heat exchanger system of  claim 7 , wherein the thickness of each of the first insulation and the second insulation is in a range of 0.6 inch to 1 inch. 
     
     
         9 . The heat exchanger system of  claim 1 , wherein the first insulation overlaps with the second insulation at the abutment. 
     
     
         10 . The heat exchanger system of  claim 1 , further comprising a foil configured to conceal the first insulation. 
     
     
         11 . A heating, ventilation, and air conditioning (HVAC) system comprising:
 a heat exchanger system comprising:
 a cabinet; 
 a V-shaped round tube plate fin heat exchanger disposed within the cabinet; 
 an axial fan housing disposed within the cabinet and located downstream of the V-shaped round tube plate fin heat exchanger; 
 a plurality of refrigerant tubes located in the V-shaped round tube plate fin heat exchanger; 
 a first insulation disposed along a first portion of an inner periphery of the cabinet, the first portion located upstream of the V-shaped round tube plate fin heat exchanger; 
 a second insulation disposed along a second portion of the inner periphery of the cabinet, the second portion located downstream of the V-shaped round tube plate fin heat exchanger, wherein, in operation, a temperature of air flowing through the second portion is less than a temperature of the air flowing through the first portion; and 
 a connecting member disposed along an abutment of the first insulation and the second insulation, wherein the connecting member is configured to conceal the abutment. 
   
     
     
         12 . The HVAC system of  claim 11 , wherein the heat exchanger system is one of an air handler or a gas furnace. 
     
     
         13 . The HVAC system of  claim 11 , wherein the first insulation comprises fiberglass. 
     
     
         14 . The HVAC system of  claim 11 , wherein the second insulation comprises foam. 
     
     
         15 . A heat exchanger system comprising:
 a cabinet;   a V-shaped, round tube plate fin heat exchanger disposed within the cabinet;   an axial fan housing disposed within the cabinet and located downstream of the V-shaped round tube plate fin heat exchanger;   a first insulation disposed along a first portion of an inner periphery of the cabinet, the first portion located upstream of the V-shaped round tube plate fin heat exchanger;   a second insulation disposed along a second portion of the inner periphery of the cabinet, the second portion located downstream of the V-shaped round tube plate fin heat exchanger, wherein, in operation, a temperature of air flowing through the second portion is less than a temperature of the air flowing through the first portion; and   a connecting member disposed along, and configured to conceal, an abutment of the first insulation and the second insulation.
