Heat exchanger and refrigeration cycle apparatus

Abstract

A heat exchanger includes a plurality of heat transfer parts arranged in a first direction and spaced apart from each other, the plurality of heat transfer parts extending in a second direction and allowing refrigerant to flow through inside the plurality of heat transfer parts; a first header extending in the first direction and connected to one end of each of the plurality of heat transfer parts; a second header extending in the first direction and connected to an other end of each of the plurality of heat transfer parts; and a support extending along the first direction and the second direction and having an opening, the support being located at at least one face of the plurality of heat transfer parts in a third direction that is perpendicular to the first direction and the second direction, the support being fixed to the first header and the second header.

1 . A heat exchanger, comprising:
 a plurality of heat transfer parts arranged in a first direction and spaced apart from each other, the plurality of heat transfer parts extending in a second direction and allowing refrigerant to flow through inside the plurality of heat transfer parts;   a first header extending in the first direction and connected to one end of each of the plurality of heat transfer parts;   a second header extending in the first direction and connected to an other end of each of the plurality of heat transfer parts; and   a support extending along the first direction and the second direction and having a frame that forms an outer periphery of the support, a partition that divides an area enclosed by the frame, and an opening,   the support being formed into meshes by assembling the frame and the partition and located at at least one face of the plurality of heat transfer parts in a third direction that is perpendicular to the first direction and the second direction, the support being fixed to the first header and the second header.   
     
     
         2 . The heat exchanger of  claim 1 ,
 wherein the opening is defined by at least one of the frame and the partition, and   wherein the partition extends diagonally to the first direction.   
     
     
         3 . The heat exchanger of  claim 2 ,
 wherein the support is joined to the plurality of heat transfer parts, and   wherein the partition projects in the third direction.   
     
     
         4 . The heat exchanger of  claim 1 ,
 wherein the support includes a first folded portion obtained by folding the support at an end of the support in the first direction, the first folded portion extending in the third direction, and   wherein the first folded portion is fixed to the first header and the second header.   
     
     
         5 . The heat exchanger of  claim 1 ,
 wherein the support includes a second folded portion obtained by folding the support at an end of the support in the second direction, the second folded portion extending in the third direction, and   wherein the second folded portion is fixed to at least one of the first header and the second header.   
     
     
         6 . The heat exchanger of  claim 5 ,
 wherein the support includes   a first portion that covers one face of the plurality of heat transfer parts in the third direction, and   a second portion that covers an other face of the plurality of heat transfer parts in the third direction, and   wherein the second folded portion connects the first portion and the second portion to each other.   
     
     
         7 . The heat exchanger of  claim 1 , wherein the support is made of a material that is more likely to be ionized than materials of which the plurality of heat transfer parts, the first header, and the second header are made. 
     
     
         8 . The heat exchanger of  claim 1 ,
 wherein the first header and the second header each include a fixing part where the support is fixed to a corresponding one of the first header and the second header, and   wherein the support is locked at the fixing part.   
     
     
         9 . A refrigeration cycle apparatus, comprising:
 the heat exchanger of  claim 1 .
