Definitions

  • This invention relates to a hot-air heating system and in particularly, to the hot-air heating system in which a heat generated from an electric heater as a heat source is emitted through a plurality of radiating pipe where a heat transfer midium is contained, whereby a warm-air heating is made available.
  • the conventional heating system using a heat transfer medium has been applied; a heat generated from a heat source is transferred to an electric heat medium and through the circulation of it, a heat air is indirectly given to some heated materials and distributed in a wider area by fan, while avoiding the local concentration heat by a direct heating method.
  • an object of this invention is to provide a hot-air heating system that can ensure a high-efficiency heating in such a manner that a heat generated from an electric heater as a heat source, is emitted through a heat transfer medium having an efficient heat transfer action.
  • Another object of this invention is to provide a hot-air heating system that can ensure an efficient heating in such a manner that a heat is emitted in a wider surface area through a heat reservoir means which reserve the heat generated from a heat source to maintain a certain temperature and some thermally connected heat transfer medium pipes.
  • Another object of this invention is to provide a hot-air heating system that can ensure less environmental contamination and reasonable facility and maintenance costs using an electric heat as heat source.
  • the hot-air heating system of this invention is characterized in that the system comprises a case having a warm-air discharge vent hole provided at the upper front part having an air-supply fan at the lower rear part; a plurality of heat transfer medium pipes having a plurality of radiating fins arranged at the outer surface; and a heat reservoir block where the lower part of the heat transfer medium pipes is connected and an electric heater is installed.
  • the heat transfer medium pipes comprise a sealed pipe body and liquid-phase heat transfer medium are contained in its inside.
  • the heat reservoir block is stacked by a plurality of plates consisting of metals with a high heat conduction .
  • the heat reservoir block may be provided in a liquidtight container form; a heat transfer medium, which is the same as that contained in the heat transfer medium pipes, may be contained in the heat reservoir block. Further, the pipe body of heat transfer medium pipes and the heat reservoir block may be fabricated in an integrated form.
  • Fig. 1 shows that the whole structure of the hot-air heating system according to this invention is dissembled.
  • the hot-air heating system of this invention comprises a case 14 having a warm-air discharge vent hole 10 provided at the front upper part and having an air-supply fan 12 at the lower rear part.
  • a heat reservoir block 16 Provided in the case 14 is a heat reservoir block 16 and a plurality of heat transfer medium pipes 18 being thermally connected with the heat reservoir block 16.
  • Electric heaters 20 are connected to the heat reservoir block 16, and and the latter serves to reserve a heat generated by the electric heaters 20 and transfer it to the heat transfer medium pipes 18.
  • the heat reservoir block 16 is stacked by a plurality of plates 22 consisting of aluminum or copper with a high conduction. Between these plates 22, the electric heater 20 as a heat source, is inserted to a recesses 24 formed to the opposite sides of the adjacent boards 22. Therefore, when the current flows into the electric heater 20 to generate a heating due to its resistance heat, the heat is transferred to the heat reservoir block 16 consisting of a plurality of plates 22. Then, in order to connect the lower part of the heat transfer medium pipe 18 to the heat reservoir block 16, a plurality of insert grooves 26 are formed to the plates 22 of the heat reservoir block 16.
  • the heat transfer medium pipe 18 comprises a sealed pipe body 28.
  • the inside of the pipe body 28 is completely filled with an organic or inorganic, non-combustible, liquid-phase heat transfer medium 30, which has a low vapor pressure with better thermal stability, less corrosiveness and large specific heat and vaporization heat, for sealing thereof.
  • the pipe body 28 is fabricated by some metals such as aluminum or copper with better heat conduction. Further, to the outer side of the pipe body 28, a plurality of radiating fins 32 whose material is the same as the pipe body 28 are formed.
  • a control panel 34 for controlling the operation of the electric heater 20 and the air-supply fan 12 are provided at the front of the case 14; at the rear side of the case 14, a temperature sensor 36 is installed so that the predetermined range of temperature can be maintained.
  • Fig. 5 shows another embodiment of the heat reservoir block; the heat reservoir block 16A has a liquidtight container where the heat transfer medium 30A, which is the same as that contained in the heat transfer medium pipe 18, along with the electric heater 20A in the heat reservoir block 16A.
  • the heat transfer medium pipe 18A and heat reservoir block 16A are fabricated in an integrated form and the same heat transfer medium may be inserted into their inside.
  • the hot-air heating system of this invention is operated in such a manner that through the control panel 34, the temperature of a heater is established and then, the current is supplied to the electric heater 20 to make a warm-air heating by the air-supply fan 12.
  • the electric heater 20, so heated generates a heat and then, the heat reservoir block 16 is heated. Since the heat reservoir block 16 having a large thermal mass, it can store a lot of heat.
  • the stored heat is transferred to the heat transfer medium pipe 18 at the predetermined range of temperature.
  • the heat reservoir block 16 is stacked by a plurality of plates 22 consisting of aluminum or copper with a high heat conduction. The lower part of the heat transfer medium pipe 18 is tightly inserted into the heat reservoir block 16.
  • the heat transfer medium 30 with better heat conduction is housed in the heat transfer medium pipe 18, the heat stored in the heat reservoir block 16 can be readily or effective transferred to the heat medium transfer pipe 18.
  • the heat is emitted via the radiating fins 32 of the heat medium transfer pipe 18, expanding the surface area of radiation to the maximum level.
  • the heat reservoir block 16 is stacked by a plurality of plates 22 consisting of metals with a high heat conduction. Since these plates can store a large amount of heat when heated by the electric heater 20, a sustained heat can be transferred to the heat transfer medium pipe 18 for a longer time, in spite of the temporal block-off of electric power.
  • this invention has several advantages in that (1) a warm-air heating with a very high efficiency can be ensured in such a manner that a radiation via electric heat is made available using a heat transfer medium with an efficient heat transfer effect, (2) an efficient heating can be also ensured in such a manner that through the heat transfer medium pipes which is thermally connected with a heat reservoir means which can maintain a certain range of temperature by storing the heat generated from a heat source, a radiation may be made available at a large surface area, and (3) the hot-air heating system with a simple structure, which required less facility investment or maintenance cost, can be utilized as a comfortable in-door heater.
