Heat exchanger and fitting

Abstract

The present invention provides a header of a heat exchanger. The header can include a tank having a tank outlet, and an integral fitting including a body extending outwardly away from the tank outlet and having an outlet located remotely from the tank outlet, an inlet located between the tank outlet and the fitting outlet, and a baffle located within the body adjacent to the inlet to direct at least a portion of a fluid flow from the inlet toward the fitting outlet.

       14 . The heat exchanger of  claim 10 , wherein the baffle is positioned between the first inlet and the second inlet. 
   
   
       15 . The heat exchanger of  claim 10 , wherein the fitting defines a first flow path between the first inlet and the fitting outlet and a second flow path between the second inlet and the fitting outlet. 
   
   
       16 . The heat exchanger of  claim 10 , wherein the body is operable to join a working fluid entering the fitting from the tank with the fluid flow entering the fitting through the second inlet downstream from the tank outlet. 
   
   
       17 . The heat exchanger of  claim 10 , wherein the baffle at least partially defines a first flow path and a second flow path. 
   
   
       18 . The heat exchanger of  claim 10 , wherein the baffle extends outwardly away from the tank past the inlet. 
   
   
       19 . The heat exchanger of  claim 10 , wherein the fitting is integrally formed with the tank. 
   
   
       20 . The heat exchanger of  claim 10 , wherein the heat exchanger is a radiator. 
   
   
       21 . A fitting of a header for a heat exchanger, the header including a tank having a tank outlet, the fitting comprising:
 a body extending outwardly away from the tank outlet and having an outlet located remotely from the tank outlet, a first inlet located adjacent to the tank outlet for receiving a working fluid from the tank, and a second inlet located on the body between the tank outlet and the fitting outlet, the body at least partially defining a first flow path between the first inlet and the fitting outlet and at least partially defining a second flow path between the second inlet and the fitting outlet.
