Abstract

PROBLEM TO BE SOLVED: To effectively spread heat of high temperature gas over the whole of a radiator in a heating apparatus using the radiator. SOLUTION: A heating apparatus is adapted to include a radiator 12, where heat diffuses over the whole thereof through thermal conduction, and the thickness of a part to which heat of high-temperature gas is less likely to be directly conducted through thermal conduction is thicker than that of the other parts and a radiator heating air passage 15, through which high temperature gas is guided to a heat collection surface 13. Hereby, the heat diffuses over the whole of the radiator through thermal conduction. Since thickness of a part to which heat of high temperature gas is less likely to be conducted directly through thermal conduction is thicker than the other parts, the quantity of thermal conduction through that part is increased. Accordingly, heat of the high temperature gas spreads over the whole of the radiator and is effectively conducted to the radiator 12.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device using combustion heat, and more particularly to a heating device using radiant heat.

[0002]

2. Description of the Related Art A conventional heating device of this kind is disclosed in
What was described in 11548 gazette was common. As shown in FIG. 4, the heating device is provided with a burner 1 provided at a lower portion of the main body, a hollow thin box-shaped heat exchanger 2 through which combustion gas from the burner 1 passes, and formed on both sides of the heat exchanger. Convection fan that blows air to the heat exchanger 2 and exchanges heat to discharge hot air from the main body discharge port. The heat exchanger 2 has a hollow inside so that the combustion gas 6 from the burner 1 passes therethrough and is provided with a passage 7, and a passage through which the combustion gas spreads to each part of the heat exchanger. 7, a concave bead 8 is provided in a part of the opening 7 and the bead 8 is discharged from the opening 3.

[0003] The combustion gas generated by the burner passes through the heat exchanger 2 and is heated to 300 to 500 ° C, so that far infrared rays are emitted from the front surface coated with far infrared paint to perform radiant heating. . At the same time, the indoor air taken in by the convection fan 5 is blown along the rear surface of the heat exchanger 2, mixed with the combustion gas discharged from the opening 3 of the heat exchanger 2, discharged into the room as warm air, and discharged as warm air. Perform heating.

[0004]

However, in the above-mentioned conventional heating apparatus, the heat transfer coefficient of the heat exchanger is about 10 W / m ² K because heat is exchanged only on one side of a flat plate. It is necessary to increase the difference between the temperature of the combustion gas and the temperature of the panel member in order to increase the temperature of the combustion gas to about 870 ° C. The heat exchanger had to be made of a material that could withstand the heat, and the heat exchanger had to be directly heated by the flame generated by the burner. Further, the thickness of the boundary layer increases as the flow of the combustion gas in the heat exchanger passage becomes downstream, and the heat transfer coefficient near the open end is lower than that near the burner, so that the radiator temperature is not uniform as a whole. There was a problem that.

[0005]

In order to solve the above-mentioned problems, the present invention comprises a high-temperature gas generating means for generating a high-temperature gas, a heat-collecting surface heated by the heat of the high-temperature gas, and a radiation surface for generating radiant energy. The radiator has a configuration in which the radiator has a configuration in which heat is diffused to the whole by heat conduction, and a radiator heating air path for guiding a high-temperature gas to the radiator.

[0006] With the above structure, since the radiator is a radiator in which heat is diffused entirely by heat conduction, heat is transmitted by heat conduction to a portion which is difficult to be heated by heat transfer with the high-temperature gas, and the heat of the high-temperature gas is transmitted to the entire projectile. Can be transmitted efficiently. Therefore, even if the temperature of the high-temperature gas is low, an average high radiator temperature can be obtained.
