NATURAL CIRCULATION METHOD OF FREE HEATING MACHINE AND NATURAL CIRCULATION METHOD OF FREE HEATING SYSTEM

摘要

The present invention relates to pre-heating unit and a pre-heating system using a natural circulation method, and more Specifically, the outside air is introduced and the inlet formed on one side, and the cover is evacuated in the form of the inlet to exhaust the heated outside air flows into the room on the other side in the vehicle; Is provided on the inside of the cover, the first suction fan for sucking the outside air controlled by the control part on one side to the inside of the cover is provided, the combustion chamber to generate heat generated in the combustion chamber is formed inside the outer periphery and that a plurality of heat exchange fins to pass to the outside air sucked into the interior of the column cover, an inlet pipe for introducing the outside air into the combustion chamber, and that the exhaust pipe to exhaust to the outside the exhaust gas generated in the combustion chamber each having and the body; Is provided in the combustion chamber of the body is ignited under the control of the control unit, the burner with the second suction fan for drawing under the control of the control unit to the outside air for the ignition through the inlet pipe of the body; It is provided on the body, the cooling water therein, and a plurality of outer heat exchange with a cool jacket is provided with fins on the periphery; Is provided on the body, the cooling water therein, and a plurality of heat exchange pins are hot jacket provided at an outer circumferential edge; being made, including the water contained in the interior of the hot jacket of the jacket and cool the hot jacket It is raised by the temperature difference between the cool and the hot jacket of which is provided a plurality of natural circulation method between the jacket characterized in that the natural circulation in the jacket to cool the hot jacket through natural circulation introducer sheath and the pre-heating apparatus using the same pre- It relates to a heating system. ; Thus configured present invention is more easily accommodated in the interior of the hot water jacket, as well as be able to heat the vehicle interior to cool the jacket and the temperature of the hot jacket increase is not necessary to circulate the cooling water in a separate pump like the prior art, since the natural circulation in the jacket to cool the hot jacket through a plurality of the natural circulation induced tube provided between the jacket and cool the hot jacket by it is effective.
