Abstract

A water injector for an aviation cooling system includes a body having a first end, a second end, and an intermediate portion extending therebetween. A conduit extends through the body from the first end to the second end. A spray nozzle is fluidically connected to the conduit and arranged at one of the first end and the second end. A mounting plate is arranged at the other of the first end and the second end. The mounting plate is configured and disposed to secure the body to an aviation cooling component. A filter is supported at the body and is fluidically exposed to the conduit. The filter is configured and disposed to capture particulate flowing into the water injector towards the spray nozzle.

First claim

What is claimed is:

1. A ram air heat exchanger comprising:
a ram air outlet;
a ram air header including a ram air inlet; and
a water injector mounted to the ram air header, the water injector comprising:
a body having a first end, a second end, and an intermediate portion extending therebetween;
a conduit extending through the body from the first end to the second end;
a spray nozzle fluidically connected to the conduit arranged at one of the first end and the second end, the spray nozzle threadingly connected to the body in a repeatedly removable manner;
a mounting plate arranged at the other of the first end and the second end, the mounting plate being configured and disposed to secure the body to an aviation cooling component; and
a filter supported at the body and fluidically exposed to the conduit, the filter being configured and disposed to capture particulate flowing into the water injector towards the spray nozzle, the filter threadingly engaged in the other of the first end and the second end in a repeatedly removable manner.

2. The ram air heat exchanger according to claim 1 , wherein the spray nozzle includes an orifice having an outlet of less than about 0.120-inches (3.05-mm).

3. The ram air heat exchanger according to claim 1 , further comprising: a sealing gasket arranged at the mounting plate, the sealing gasket being configured and disposed to seal an interface between the water injector and the aviation cooling component.
