Abstract

A charge air cooler cover includes a nozzle configured for connection to an outlet of a compressor for receiving charge air, a tray configured for connection to an inlet of a charge air cooler, and a plenum leading from the nozzle to a plurality of passages defined by a plurality of ribs. The plurality of passages connects the plenum to the tray. The ribs and the tray are arranged to achieve substantially uniform charge air velocity across the inlet of the charge air cooler, in at least one mode of operation.

First claim

What is claimed is:

1. A charge air cooler cover comprising:
a nozzle configured for connection to an outlet of a compressor for receiving charge air;
a tray configured for connection to an inlet of a charge air cooler; and
a plenum leading from the nozzle to a plurality of passages defined by a plurality of ribs, the plurality of passages connecting the plenum to the tray;
wherein the plurality of ribs are configured to divert, proportion and straighten or collimate a flow of the charge air from the nozzle toward the tray;
wherein the ribs and the tray are arranged to achieve uniform charge air velocity across the inlet of the charge air cooler; and
wherein the plurality of ribs define the plurality of passages to have differing flow areas, wherein a first of the plurality of passages furthest from the nozzle is defined to have the largest flow area among the plurality of passages and a second of the plurality of passages closest to the nozzle is defined to have the smallest flow area among the plurality of passages.

2. The charge air cooler cover of claim 1 , wherein the plurality of ribs define the plurality of passages to have differing flow areas, the respective flow area of each passage depending on distance of that passage from the nozzle.

3. The charge air cooler cover of claim 2 , wherein the passage furthest from the nozzle is defined to have the largest flow area among the plurality of passages.

4. A system comprising:
an engine;
a charge air cooler cover having a nozzle configured for connection to an outlet of a compressor for receiving charge air, a tray configured for connection to an inlet of a charge air cooler, and a plenum leading from the nozzle to a plurality of passages defined by a plurality of ribs, the plurality of passages connecting the plenum to the tray;
a turbocharger operably coupled to the engine and comprising the compressor and a turbine; and
the charge air cooler, wherein the charge air cooler is operably coupled to receive the charge air from the compressor through the charge air cooler cover;
wherein the nozzle of the charge air cooler cover is connected to the outlet of the compressor for receiving the charge air, and the tray is connected to the inlet of the charge air cooler; and
wherein the plurality of ribs are configured to diver, proportion and straighten or collimate a flow of the charge air from the nozzle toward the tray;
wherein the ribs and the tray are arranged to achieve uniform charge air velocity across the inlet of the charge air cooler; and
wherein the plurality of ribs define the plurality of passages to have differing flow areas, wherein a first of the plurality of passages furthest from the nozzle is defined to have the largest flow area among the plurality of passages and a second of the plurality of passages closest to the nozzle is defined to have the smallest flow area among the plurality of passages.

5. The system of claim 4 , wherein in at least one mode of operation of the system where the charge air cooler cover receives the charge air from the compressor and channels it to the charge air cooler, the ribs and the tray of the charge air cooler cover achieve the uniform charge air velocity across the inlet of the charge air cooler.

6. A system comprising:
an engine;
a first turbocharger operably coupled to the engine and comprising a first compressor and a first turbine;
a second turbocharger operably coupled to the engine and comprising a second compressor and a second turbine;
a first charge air cooler;
a first charge air cooler cover having a nozzle configured for connection to an outlet of a compressor for receiving charge air, a tray configured for connection to an inlet of a charge air cooler, and a plenum leading from the nozzle to a plurality of passages defined by a plurality of ribs, the plurality of passages connecting the plenum to the tray, wherein the nozzle of the first charge air cooler cover is connected to the outlet of the first compressor for receiving the charge air, and the tray of the first charge air cooler cover is connected to an inlet of the first charge air cooler;
a second charge air cooler; and
a second charge air cooler cover having a nozzle configured for connection to an outlet of a compressor for receiving charge air, a tray configured for connection to an inlet of a charge air cooler, and a plenum leading from the nozzle to a plurality of passages defined by a plurality of ribs, the plurality of passages connecting the plenum to the tray, wherein the nozzle of the second charge air cooler cover is connected to the outlet of the second compressor for receiving the charge air, and the tray of the second charge air cooler cover is connected to an inlet of the second charge air cooler;
wherein the first charge air cooler cover and the second charge air cooler cover have at least one of a different number of passages, a differently shaped tray or differently shaped ribs from one another.
