Abstract

A heat exchange system and apparatus for a vehicle powertrain configured to exchange heat between a first fluid and a second fluid within a heat exchanger core formed by a plurality of stacked plates having separate channels for the first fluid and the second fluid. The heat exchanger system includes multiple heat exchangers, one of which is connected to a both the inlet and the outlet of a vehicle powertrain component, another of which is fluidly connected or at least partially disconnected from the vehicle component according to the mode of operation of the heat exchange system. The heat exchanger connected to the vehicle component includes a jumper tube to return the first fluid to the vehicle component through a core of the heat exchanger.

First claim

What is claimed is:

1. A heat exchanger comprising:
a core having a plurality of stacked plates, flow channels for a fluid arranged between the stacked plates;
a first manifold at least partially defined by first aligned apertures located in a first corner of at least some of the stacked plates, the first manifold being in fluid communication with a least some of the flow channels;
a second manifold at least partially defined by second aligned apertures located in a second corner of the stacked plates, the second manifold being in fluid communication with the flow channels;
a first inlet port and a first outlet port arranged at a first end of the heat exchanger;
a second inlet port and a second outlet port arranged at a second end of the heat exchanger opposite the first end;
a first fluid flow path extending through the heat exchanger between the first inlet port and the second outlet port, the first fluid flow path including the flow channels, the first manifold, and the second manifold;
a second fluid flow path extending through the heat exchanger between the second inlet port and the first outlet port, the first and the second fluid flow paths being fluidly isolated from one another within the heat exchanger;
a jumper tube extending through the second aligned apertures in the second corner of the stacked plates, wherein the second fluid flow path extends through the jumper tube;
a third manifold at least partially defined by third aligned apertures located in the first corner of at least some of the stacked plates, the third manifold being in fluid communication with a least some of the flow channels, the first fluid flow path extending through the third manifold, the first manifold and the third manifold being fluidly connected to each other along the first fluid flow path by way of the flow channels and the second manifold;
a flange plate arranged at the first end, the first inlet port and the first outlet port being provided in the flange plate;
a channel plate arranged between and joined to the flange plate and the plurality of stacked plates;
a first channel arranged within the channel plate and extending between the first inlet port and a location corresponding to the first corner of the plates, the first channel being in fluid communication with the first manifold and the first inlet port so that the first fluid flow paths extends through the first channel; and
a second channel arranged within the channel plate and extending between a location corresponding to the second corner of the plates and the first outlet port, the second channel being in fluid communication with the jumper tube so that the second fluid flow path extends through the second channel.

2. A heat exchanger comprising:
a core having a plurality of stacked plates, flow channels for a fluid arranged between the stacked plates;
a first manifold at least partially defined by first aligned apertures located in a first corner of at least some of the stacked plates, the first manifold being in fluid communication with a least some of the flow channels;
a second manifold at least partially defined by second aligned apertures located in a second corner of the stacked plates, the second manifold being in fluid communication with the flow channels;
a first inlet port and a first outlet port arranged at a first end of the heat exchanger;
a second inlet port and a second outlet port arranged at a second end of the heat exchanger opposite the first end;
a first fluid flow path extending through the heat exchanger between the first inlet port and the second outlet port, the first fluid flow path including the flow channels, the first manifold, and the second manifold;
a second fluid flow path extending through the heat exchanger between the second inlet port and the first outlet port, the first and the second fluid flow paths being fluidly isolated from one another within the heat exchanger;
a jumper tube extending through the second aligned apertures in the second corner of the stacked plates, wherein the second fluid flow path extends through the jumper tube;
a flange plate arranged at the first end, the first inlet port and the first outlet port being provided in the flange plate;
a channel plate arranged between and joined to the flange plate and the plurality of stacked plates; and
a channel arranged within the channel plate and extending between a location corresponding to the second corner of the plates and one of the first inlet port and first outlet port, the channel being in fluid communication with one of the second manifold and the jumper tube so that one of the first and second fluid flow paths extends through the channel.

3. The heat exchanger of claim 2 , wherein the channel arranged within the channel plate is in fluid communication with the second manifold and wherein the jumper tube extends through the channel and is joined to the flange plate in a leak-free fashion.

4. A heat exchanger comprising:
a core having a plurality of stacked plates, flow channels for a fluid arranged between the stacked plates;
a first manifold at least partially defined by first aligned apertures located in a first corner of at least some of the stacked plates, the first manifold being in fluid communication with a least some of the flow channels;
a second manifold at least partially defined by second aligned apertures located in a second corner of the stacked plates, the second manifold being in fluid communication with the flow channels;
a first inlet port and a first outlet port arranged at a first end of the heat exchanger;
a second inlet port and a second outlet port arranged at a second end of the heat exchanger opposite the first end;
a first fluid flow path extending through the heat exchanger between the first inlet port and the second outlet port, the first fluid flow path including the flow channels, the first manifold, and the second manifold;
a second fluid flow path extending through the heat exchanger between the second inlet port and the first outlet port, the first and the second fluid flow paths being fluidly isolated from one another within the heat exchanger;
a jumper tube extending through the second aligned apertures in the second corner of the stacked plates;
a cover plate joined to the top plate; and
one or more connection blocks joined to the cover plate, the second inlet port and the second outlet port being arranged in the one or more connection blocks,
wherein the second fluid flow path extends through the jumper tube; wherein the plurality of stacked plates includes a bottom plate arranged at one end of the stack of plates and a top plate arranged at the opposing end of the stack of plates, the jumper tube being joined to at least one of the bottom plate and the top plate in a leak-free fashion, and
wherein the cover plate includes one or more formed areas that define one or more cover plate flow channels between the cover plate and the top plate, the one or more cover plate flow channels including at least one of a flow channel fluidly connecting the second outlet port to the first manifold and a flow channel fluidly connecting the second inlet port to the jumper tube.

5. The heat exchanger of claim 4 , wherein the jumper tube is joined to both the bottom plate and the top plate in a leak-free fashion.
