Abstract
A heat exchanger includes a first header and tank assembly having an inlet port and an outlet port. First and second tubes are included, each tube in fluid communication with the first header and tank assembly and with the other tube. An elastomeric baffle is disposed in the first header and tank assembly to substantially prevent fluid flow between the inlet port and the outlet port except through the first and second tubes.
Claims11
A heat exchanger comprising:
- a first header and tank assembly having an inlet port and an outlet port;
- the first header and tank assembly including an apertured header and a tank attached to the header;
- first and second tubes, each tube in fluid communication with the first header and tank assembly and with the other tube;
- the first and second tubes each having a first end in fluid communication with and received in the apertured header;
- an elastomeric baffle disposed in the first header and tank assembly to substantially prevent fluid flow between the inlet port and the outlet port except through the first and second tubes;
- the baffle being disposed between the header and the tank, the header and the tank elastically compressing the baffle between opposing surfaces on the header and the tank;
- the tank having a rib formed in the opposing surface of the tank and directed toward said header;
- and
- the baffle having an indentation therein which conforms to and receives the rib to locate the baffle in a desired position between the inlet port and the outlet port.
