PCM automotive exhaust heat storage for connection to domestic hot water and heating systems

摘要

Apparatus for using the exhaust heat of internal combustion engines as heating heat for service water and / or apartments, installed in a car body (F + M + N), consisting of the following individual components: a) Thermally insulated exhaust pipe between the catalyst and the Nutzsystem to be described later b) heat exchanger and heat storage consisting of concentric shells as follows: aa) The innermost shell represents the exhaust duct (O) into which the exhaust gases are fed by the engine. In this shaft, which is bounded by a good heat-conducting metal wall (L), there is a honeycomb z. B. metallic heat conductor (E + K), which passes through the wall and thus promotes the heat exchange and removal positively. This honeycomb shaft is simultaneously designed as a resonance muffler. bb) The middle shell is bounded on both sides by metal walls (C + L), wherein the outer wall (C) as possible a poor heat conductor, eg. B. stainless steel represents. The shell is filled with a PCM medium (D) and traversed by the ...
