Integrated multi-chamber heat exchanger
A one-piece heat exchanger manufactured using an additive manufacturing process is described. The heat exchanger includes a plurality of channels formed therein. At least some of the plurality of channels may be configured to provide structural support to the heat exchanger to reduce its weight. Different coolant media may be used in a first set and a second set of the plurality of channels to provide different types of cooling in an integrated one-piece heat exchanger structure.
1. A method of manufacturing a heat exchanger, the method comprising:
forming, using an additive manufacturing process, a one-piece body and a plurality of channels formed in the one-piece body, wherein forming the plurality of channels comprises:
connecting a first set of channels of the plurality of channels to a first inlet and a first outlet formed in the one-piece body, wherein the first set of channels is configured to provide cooling using a first coolant media that flows in a first direction between the first inlet and the first outlet, wherein the first inlet and the first outlet are arranged on a first side of the heat exchanger; and
connecting a second set of channels of the plurality of channels to a second inlet and a second outlet formed in the one-piece body, wherein the second set of channels is configured to provide cooling using a second coolant media that flows in a second direction opposite the first direction between the second inlet and the second outlet, wherein the second inlet and the second outlet are arranged on a second side of the heat exchanger opposite the first side, and wherein the second coolant media is different than the first coolant media,
wherein each of the channels in the first set of channels and the second set of channels has a same shape.
2. The method of claim 1 , wherein forming the one-piece body comprises forming at least one mounting structure as a portion of the one-piece body.
3. The method of claim 1 , wherein forming the plurality of channels comprises forming the first set of channels to have a combined volume greater than a combined volume of the channels in the second set of channels.
4. The method of claim 1 , wherein forming the plurality of channels comprises forming at least some of the all channels in the first set of channels to have a diamond shape.
