Heat exchanger, outdoor unit and refrigeration apparatus

Abstract

A heat pump chiller includes a casing having a compressor, etc. inside thereof and four flat-plate shaped air heat exchangers disposed on side surfaces of the casing and extending vertically. Two air heat exchangers constitute a first heat exchanger body and a second heat exchanger body. Respective heat exchanger bodies are positioned with end parts extending toward outside of the air heat exchangers to be close to each other.

1 . A heat exchanger which is placed on a both side surface of a casing and includes a first heat exchanger body and a second heat exchanger body each extending along a side surface of the casing,
 wherein each of the first heat exchanger body and the second heat exchanger body includes linear shaped first and second heat exchanger parts extending toward outside of the casing so that a middle part forms a top part of an obtuse angle positioned outside of the casing in plan view.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein the first heat exchanger part and the second heat exchanger part are configured to be independent of each other, and
 the first heat exchanger part and the second heat exchanger part of the respective heat exchanger bodies are positioned so that end parts forming the top part are close to each other.   
     
     
         3 . The heat exchanger according to  claim 2 , wherein the first heat exchanger body and the second heat exchanger body are positioned so that end parts of the first heat exchanger body and end parts of the second heat exchanger body are positioned to have a predetermined distance. 
     
     
         4 . An outdoor unit comprising the casing and the heat exchanger of any one of  claims 1  to  3 . 
     
     
         5 . The outdoor unit according to  claim 4 , wherein the casing and the heat exchanger together form an outdoor unit body, and
 multiple ones of the outdoor unit body are provided in the outdoor unit to be arranged in parallel in a width direction.   
     
     
         6 . The outdoor unit according to  claim 4 , wherein the casing includes a fan mechanism for providing air to the first heat exchanger body and the second heat exchanger body in the area that is enclosed by the first heat exchanger body and the second heat exchanger body. 
     
     
         7 . The outdoor unit according to  claim 4 , wherein an air guide part is disposed outside of the first heat exchanger body and the second heat exchanger body to feed air to the respective heat exchanger bodies. 
     
     
         8 . A refrigeration apparatus, comprising an outdoor unit described in  claim 4 .
