Heat exchanger arrangement

Abstract

The invention relates to a heat exchanger arrangement including an air heat exchanger arranged in a thermally insulated housing chamber; a defrosting device; and a fan, wherein the housing chamber itself forms an air flow cavity and is segmented by the air heat exchanger into an inflow cavity and an outflow cavity, and wherein the air heat exchanger includes adjustable flaps which are configured on an air inlet side and on an air outlet side of the heat exchanger to regulate or block an airflow path.

1 . A heat exchanger arrangement, comprising:
 an air heat exchanger arranged in a thermally insulated housing chamber;   a defrosting device; and   a fan,   wherein the housing chamber itself forms an air flow cavity and is segmented by the air heat exchanger into an inflow cavity and an outflow cavity, and   wherein the air heat exchanger includes adjustable flaps which are configured on an air inlet side and on an air outlet side of the heat exchanger to regulate or block an airflow path.   
     
     
         2 . The heat exchanger arrangement according to  claim 1 , wherein the flaps are configured thermally insulated and vapor tight. 
     
     
         3 . The heat exchanger arrangement according to  claim 1 , wherein the housing chamber includes a walkable base plate which is configured air permeable as an intake portion in the inflow cavity. 
     
     
         4 . The heat exchanger arrangement according to  claim 1 , wherein the fan is arranged in the outflow cavity of the housing chamber. 
     
     
         5 . The heat exchanger arrangement according to  claim 1 , wherein the fan is arranged on the base plate and connected on a pressure side of the fan with an air duct. 
     
     
         6 . The heat exchanger arrangement according to  claim 1 , wherein the housing chamber includes an inspection door. 
     
     
         7 . The heat exchanger arrangement according to  claim 1 , wherein the defrosting device includes heating rods integrated into the air heat exchanger and a condensate drain pan. 
     
     
         8 . The heat exchanger arrangement according to  claim 1 ,
 wherein the housing chamber is configured from a base frame with insulation elements, and   wherein supports are configured as hanging rods at the base frame.   
     
     
         9 . The heat exchanger arrangement according to  claim 1 ,
 wherein a first air flow direction during entry into the housing chamber and a second airflow direction during exit from the housing chamber are oriented in vertical direction, parallel and opposite to one another, and   wherein the air flow through the air heat exchanger is oriented horizontal,   wherein the flaps are positionable to cause air flow control, air flow deflection and air flow volume dosing.   
     
     
         10 . The heat exchanger arrangement according to  claim 1 , wherein the flaps are configured to cover and thermally insulate the air inlet and the air outlet side of the air heat exchanger so that the air heat exchanger is thermally insulated relative to the outside for defrosting.
