Heat exchanger drain assembly having a frangible wall

摘要

A heat exchanger (10) having a heat exchanger drain assembly (28) comprising a manifold (12) for storing fluid. A drain port (20) is integrally formed with the manifold (12) and is in selective fluid communication with the reservoir (36) for selectively draining the fluid from the manifold (12). A plug (32) is disposed within the drain port (20) for preventing fluid from draining from the manifold (12). The plug (32) is removable from the drain port (20) for allowing fluid to drain from the manifold (12). A frangible wall (40) is formed between the drain port (20) and the reservoir (36) to close the drain port (20) and create a non-functional drain port (20), thereby preventing fluid communication between the drain port (20) and the reservoir (36). The frangible wall (40) is fracturable to provide the fluid communication between the drain port (20) and the reservoir (36) for draining the fluid from the tank (12).
