Abstract
A heat exchange assembly includes an upper cover panel, a lower cover panel, a plurality of stacked plate assemblies, and a plurality of fins interposed between the plurality of plate assemblies. Each of the plurality of plate assemblies forms a flow passage for receiving a coolant. A continuous flow path extends through the heat exchange assembly. The flow path is in fluid communication with the flow passage of each of the plates and configured to convey air from each of the flow passages to an environment separate from the heat exchanger.
Claims9
A heat exchanger comprising:
- a heat exchange assembly including an upper cover panel, a lower cover panel, a plurality of stacked plate assemblies, and a plurality of fins interposed between the plate assemblies, each of the plate assemblies forming a flow passage for receiving a coolant;
- and
- a continuous flow path extending through the heat exchange assembly, the flow path in fluid communication with the flow passages of each of the plate assemblies and configured to convey air from each of the flow passages to an environment separate from the heat exchanger;
- wherein a first portion of the continuous flow path is formed by a degas channel extending through the plurality of plate assemblies, the degas channel in direct fluid communication with each of the flow passages, the upper cover panel including a degas outlet, a second portion of the continuous flow path formed by a degas outlet manifold in direct fluid communication with the degas outlet, a third portion of the continuous flow path including a groove formed in the lower cover panel, the groove providing direct fluid communication between the degas channel and the degas outlet manifold, the degas channel is spaced apart from the flow passages, a coolant inlet manifold and a coolant outlet manifold.

A heat exchanger comprising:
- an upper cover panel including a degas outlet for conveying air from the heat exchanger;
- a lower cover panel including a groove formed therein;
- and
- a plurality of plate assemblies disposed intermediate the upper cover panel and the lower cover panel, each of the plurality of plate assemblies forms a flow passage for receiving a coolant that flows through the plurality of plate assemblies, the plurality of plate assemblies aligning with each other to form at least one degas channel and at least one degas outlet manifold extending through the plurality of plate assemblies, the at least one degas channel and the at least one degas outlet manifold configured to receive and convey air from each of the flow passages to an environment outside of the heat exchanger, the groove providing direct fluid communication between the at least one degas channel and one of the at least one degas outlet manifold, wherein the one of the at least one degas outlet manifold is in direct fluid communication with the degas outlet;
- and the at least one degas channel is spaced apart from the flow passages, a coolant inlet manifold and a coolant outlet manifold.
