Refrigerant Distribution Device

Abstract

The present invention aims to provide a refrigerant distribution device which eliminates a need for maintaining a certain length of a straight portion at an inflow tube to a distributor, and for adjusting lengths of capillary tubes to send a refrigerant to each flow path of the refrigerant of a heat exchanger, and which resolves an unevenness of a liquid refrigerant at a bend of the inflow tube due to a centrifugal force. A refrigerant distribution device according to the present invention including an inflow tube, which is connected to a distributor for distributing and providing a refrigerant in a gas-liquid two-phase state to a heat exchanger, wherein an upstream side of the inflow tube is in an approximately horizontal position and a downstream side of the inflow tube is bent to stand approximately at a right angle, includes a bend of the inflow tube, a longitudinal form of which is made of a combination of straight lines and is bent approximately at a right angle.

1 . A refrigerant distribution device, including an inflow tube connected to a distributor for distributing and providing a refrigerant in a gas-liquid two-phase state to a heat exchanger wherein an upstream side of the inflow tube is in an approximately horizontal position and a downstream side of the inflow tube is bent to stand approximately at a right angle, the refrigerant distribution device comprising: 
 a bend of the inflow tube of which a longitudinal form is made of a combination of straight lines and is bent approximately at a right angle.    
   
   
       2 . The refrigerant distribution device according to  claim 1 , further comprising: 
 a depression formed near an opposing wall, which faces an inflow direction of a refrigerant, of the bend.    
   
   
       3 . The refrigerant distribution device according to  claim 2 , further comprising a T-tube including connection ports in three directions, 
 wherein a connection port at a foot of the T-tube is connected to the distributor, and    wherein one connection port of both ends at a head of the T-tube is connected to a connecting copper tube forming an upstream side of the inflow tube, and the other connection port is sealed to form the depression near the bend.    
   
   
       4 . The refrigerant distribution device according to  claim 1 , 
 wherein the distributor is at an angle ranging from 30 through 150 degrees with respect to a horizontal direction.    
   
   
       5 . The refrigerant distribution device according to  claim 2 , 
 wherein the distributor is at an angle ranging from 30 through 150 degrees with respect to a horizontal direction.    
   
   
       6 . The refrigerant distribution device according to  claim 3 , 
 wherein the distributor is at an angle ranging from 30 through 150 degrees with respect to a horizontal direction.
