Abstract
A heat exchanger core consists of first and second fluid channels, each configured to direct flow of respective fluids through the heat exchanger core. Each first fluid channel includes first fluid flow assemblies having inner channels formed by inner channel walls that contain the first fluid, each inner channel surrounded by a barrier channel having a barrier channel wall that isolates the barrier channel from the second fluid. One or more barrier channel vanes support the inner channel within the barrier channel. Each barrier channel provides a void space between the inner channel wall and the barrier channel wall, thereby fluidly separating the first fluid from the second fluid. Each barrier channel can receive the first or second fluid in the event of a breach of the inner channel wall or the barrier channel wall, thereby preventing intra-fluid contamination.
