Heat exchanger having parallel connected refrigerant coil pipes

Abstract

A heat exchanger having refrigerant coil pipes connected in parallel is disclosed. The heat exchanger has a plurality of heat dissipating fins and a plurality of layers of refrigerant coil pipes which pass through the fins transversally. The plurality of refrigerant coil pipes are connected in parallel and then high pressure refrigerant driving by an air compressor is force into the refrigerant coil pipes. Air channels are formed between the refrigerant coil pipes and the fins.

What is claimed is:  
     
         1 . A heat exchanger having refrigerant coil pipes connected in parallel; the heat exchanger having a plurality of heat dissipating fins and a plurality of layers of refrigerant coil pipes which pass through the fins transversally, characterized in that: the plurality of refrigerant coil pipes are connected in parallel and then high pressure refrigerant driving by an air compressor is force into the refrigerant coil pipes; and air channels are formed between the refrigerant coil pipes and the fins.  
     
     
         2 . The heat exchanger as claimed in  claim 1 , wherein inlets of various layers of refrigerant coil pipes are connected in parallel so that the high pressure refrigerant of the air compressor is driven into a refrigerant guide-in pipe and then further enters into the plurality of layers of refrigerant coil pipes.  
     
     
         3 . The heat exchanger as claimed in  claim 1 , wherein outlets of the plurality of layers of refrigerant coil pipes are connected in parallel for being collected, thereby, the condensed refrigerant is guided out.  
     
     
         4 . The heat exchanger as claimed in  claim 1 , wherein various of refrigerant guide-in pipes are grouped; outlets of various groups are connected in parallel to a respective refrigerant guide-out pipe; and then all the refrigerant guide-out pipes are collected.
