Flameproof pressure-tight encapsulated housing with cooling device

摘要

A pressure-tight encapsulated housing (10) having a temperature control device (20) including a first heat exchanger unit (21) arranged in the interior of the housing (10) and a second heat exchanger unit (22) arranged outside of the housing (10) and which are connected to one another via a liquid cycle (23). The liquid cycle (23) includes a feed line (24) and a return line (25) each connected to the first heat exchanger unit (21) and which each fluidically connect to a passage channel (27) of a respective leadthrough unit (26) arranged in flameproof manner in a wall (13) of the housing (10) so that the passage channel (27) extends through the wall (13). The control device (20) further includes a liquid monitoring sensor (41) for generating a liquid monitoring signal (F) characteristic of the filling of the passage channels (27) with liquid, and a monitoring unit (40) for receiving signals generated by the liquid monitoring sensor (41).
