LNGC LNGC glycol water heater Flameproof enclosure assembly method

摘要

The present invention relates to a flameproof structure for an LNGC glycol water heater including a shell in which an inner space is formed and glycol water flows, a heating pipe around which magnesium oxide is filled with a coil inserted in a hollow stainless element in the shell, and a terminal box capable of supplying electricity. More particularly, the present invention relates to a flameproof structure for an LNGC glycol water heater in which an opening portion is formed at an end of the terminal box, a cover is fastened to the opening portion, and the terminal box and the cover are screw-coupled to each other. In the flameproof structure assembly method according to the present invention, the cover and the terminal box are thread-coupled, and thus exhaust gas is naturally discharged to the outside in the event of intra-heater explosion. Accordingly, internal pressure is removed and flames are prevented from leaking out by the threads, which are significant effects of the present invention.
