Abstract:
1. A method of forming a lamination cooling system, comprising: injecting a sealant between a plurality of laminations in a lamination stack using an adequate hydrostatic pressure to inject the sealant between the plurality of laminations, wherein each lamination defines an aperture, wherein the aperture of each lamination is at least partially coincident with the apertures of adjacent laminations such that the apertures define a cooling-fluid passageway through the lamination stack, wherein the sealant forms a seal to prevent a liquid cooling fluid in the passageway from exiting the lamination stack between adjacent laminations, and wherein the step of injecting includes injecting the sealant into the passageway, the sealant being at a pressure adequate to force the sealant to flow between adjoining laminations; and then removing enough sealant from the passageway to configure it as a sealed conduit capable of passing cooling fluid from a first end of the passageway to a second end of the passageway; wherein the step of injecting includes injecting the passageway with sealant, removing excess sealant from the passageway, and forcing sealant further into voids between the laminations using pressurized air.
