Figs. 1 and2 . - Herein, the
enclosure member 10 is an element where constituent elements which will be described later are filled and installed, and that serves to form the entire outer appearance of the lower heat-generating device 1. Theenclosure member 10 has afilling space 11 defined therein and a plurality of fasteningholes 12 formed on a bottom surface thereof. In addition, theenclosure member 10 is opened at a top thereof. - The
enclosure member 10 may be formed in a quadrangular shape having various sizes. Theenclosure member 10 is formed to have the fillingspace 11 therein in such a manner that four sidewalls having a predetermined height protrudingly extends vertically upwardly from a bottom of theenclosure member 10. The fastening holes 12 serves to allow fixing bolts weldingly fixed to the underside of the deck to which the lower heat-generating device 1 is mounted to be fastened with fixing nuts on the underside of theenclosure member 10 therethrough. In this case, the fastening holes 12 are not formed at regions where theheating cable 30 is arranged. In addition, the aforementioned connectinghole 13 serves to allow a connectingcable 51 connected to thecontroller 50 which will be described later to be introduced into theenclosure member 10 therethrough. - The heat-insulating
member 20 is filled within the fillingspace 11 of theenclosure member 10 as described above, and serves to prevent heat released from theheating cable 30 from being transferred to the bottom, but not in the direction of the ship deck. In other words, the heat-insulatingmember 20 prevents heat from being released to the bottom and releases the heat from the heating cable to only the upper deck so as to increase the heat efficiency of the lower heat-generating device. The heat-insulatingmember 20 preferably employs a conventional heat-insulating material for heat release and water proof purpose.

heating cable 30 is exothermically arranged on the heat-insulatingmember 20 filled in the fillingspace 11, and serves to generate heat by itself through the electric power supplied under the control of thecontroller 50 so that the generated heat is transferred to the ship deck to prevent the ship deck from being frozen. - The
heating cable 30 employs aconventional heating cable 30, and the heat-insulatingmember 20 on which theheating cable 30 is seated may have a groove (not shown) formed thereon to correspond to the shape of theheating cable 30. In the case where the top surface of the heat-insulatingmember 20 is not coated with a refractory material, a separate refractory film may be interposed between the heat-insulatingmember 20 and theheating cable 30. - In addition, the fixing

The fixingmember 40 employs a conventional aluminum tape, and is closely attached to theheating cable 30 without any spacing so that the shape of theheating cable 30 seated on the heat-insulatingmember 20 is exposed to the outside. - In the meantime, the
controller 50 is mounted at the outside of theenclosure member 10 and is electrically connected to theheating cable 30 by means of the connectingcable 51 so that the controller controls the generation of heat from theheating cable 30 and the supply of electric power. Thecontroller 50 is mounted at a rail of the ship deck by one relative to threeenclosure members 10 as shown inFig. 3 . In this case, theheating cables 30 ofadjacent enclosure members 10 may be designed to be connected to one another so that the generation of heat from theheating cable 30 and the supply of electric power can be controlled by asingle controller 50. Alternatively, a temperature sensor may be additionally mounted at thecontroller 50 so that electric power can be supplied to theheating cable 30 below a predetermined temperature, and the supply of electric power can be interrupted above the predetermined temperature. - Hereinafter, the entire installation method of the lower heat-generating device for a deck in a ship in accordance with an embodiment of the present invention will be described in detail with reference to

Aheat diffusion member 80 may be filled in theair layer 60 in such a manner that the shape of theheat diffusion member 80 corresponds to that of theair layer 60 as shown inFig. 4 . Theheat diffusion member 80 serves to rapidly transfer heat released from theheating cable 30 to the ship deck. - In addition, the heat-insulating
member 20 may further include a plurality ofconcave depressions 70 formed at a region of theair layer 60 where the heating cable is not arranged so as to increase the volume of theair layer 60 and thus improve the heat-insulating effect as shown inFig. 5 .
