Axially assembled enclosure for electrical fluid heater and method

摘要

A metal honeycomb heater is protectively mounted in an axially assembled enclosure comprising opposing tubular enclosure sections incorporating internal bore stops and a resilient mounting material to support the heater. An axial force of predetermined magnitude is applied to the sections during assembly, preloading the resilient mounting material and generating a selected spring tension and preloading force on the honeycomb. The sections are fastened together under this force so that the preloading force and spring tension are retained during subsequent use of the assembly.
