Abstract
A sloped heat exchange element is sealingly mounted above the bottom of the tank of a railway tank car adjacent each end of the tank. Each heating element is thermally isolated from the tank cradles and bolsters, which detrimentally act as heat sinks in conventional heated tank cars. The sloped heat exchangers can be manufactured into the car or retrofit into tank cars not previously having heat coils or they can be retrofit into tank cars having either internal or external heating coils.
