For this reason, there are the following problems.
(b) The heat generated by the shielded heater causes the filled oil to convect in the oil pipe and radiator. is the slowest among heating appliances, requiring more than an hour. When the outside air temperature is 10°C or less, even if the maximum electric power is used, auxiliary heating is mainly performed at around 20°C, and the room temperature does not rise even if energy saving is performed by timer control, resulting in high power operation.
(b) The generated heat and radiant heat are also low, especially the floor surface is in a low temperature state for a long time, and the power consumption is the largest compared to other heaters, and the purpose of the heating effect is lost.
(c) Compared to electric heating appliances such as electric heaters, the heat conversion efficiency of electric power is the lowest due to the thermal characteristics of oil.
(d) The equipment configuration is made of iron, and the enlargement of the heat dissipation area of the radiator requires welding work, heat distortion correction processing, and manual work that requires assembly work. A large effect cannot be expected from an increase in
(e) Due to the structure of the radiator, the radiant surfaces face each other and the radiant heat effect cannot contribute directly to the heating effect due to its structure. Heating is unique on both sides, but the advantage is that the heat energy in the non-heating direction converges rapidly in the heating direction. room temperature should be increased.
(f) Home appliance manufacturers have promoted research and development of hardware such as heaters with built-in oil pipes, but technical literature shows how difficult it is to raise the room temperature by 1°C.
(g) The oil heater does not have the ability to convey the warm air of the air conditioner.
(h) Restoration of warm air lost by opening and closing doors and windows takes time because the temperature is low.
(i) Sealed heaters, filled oil pipes, and radiator temperatures of around 70°C have no room for improvement with kerosene stoves and electric heaters, and cannot be compared.
(J) It is completely useless in buildings with high ceilings and atrium structures.
(k) If there is no wind, there are almost no options for improvement.
(e) Devise and implement a method to increase heat exchange efficiency, reduce power consumption, and obtain the maximum room temperature rise heating effect with minimum power for a decarbonized society.

よる熱交換、暖房前面部の直接熱輻射効果は予想を超えた結果である。In the oil heater, the oil pipe inside the heater, the heat-generating part of the radiator, and the floor surface directly below are all open, so that a large amount of heating energy that is unnecessary for directly generating warm air is dissipated. To solve the problem, two fan motors are fixed to the upper part of the aluminum sheet metal heat exchange cover on both sides of the operation panel, and the aluminum rear cover narrows the heat exchange air flow path to reduce the air to be heated, and the fan motor generates a heater. A major feature is the method of concentrating heat by exchanging heat and increasing the temperature. At the time of drafting, the generated air flow collides with the oil pipe directly below the fan motor, and the front surface of the heat exchange cover extends to the lower surface of the upper oil pipe, and heat is exchanged to the lower oil pipe. Therefore, it was assumed that the main airflow would be divided into two and scatter in the tangential direction of the pipe after it collided with the upper pipe. It is a big discovery that can be reproduced regardless of the placement of the heat sink between the radiators.
Aluminum U-pipe φ19, t = 1.1mm is placed upside down to expand the heat transfer area between radiators, which is easier to process than a sheet metal radiator. A narrow space is constructed with sheet metal equipment to further improve heat exchange efficiency, and a U-shaped arrangement is arranged. During this time, the radiator fins facing each other in the straight pipe part of the U-pipe radiant heat is transferred to the heating direction and the rear cover side by the heat radiation function between the radiators by the U-shaped radiator with a circular cross section, and the heat is divided into two air currents. It promotes the exchanged convergence effect and raises the airflow to a high temperature, resulting in rapid heating with no waste, and the heat recovery is similar to that of the sheet metal radiator.
The reflector plate is fixed between the caster bases fixed on both sides of the lower oil pipe with a U bolt, and the two lower oil pipes are sandwiched from the upper part, and the two positions between the caster bases are fixed at the lower part through the drilled holes in the lower part of the reflector wind direction plate. In order to place the rear cover on both caster bases, the rear part of the reflector is bent at a right angle so that the rear cover does not come off from the upper part of the caster. do.
The airflow from the rear cover is rectified by the reflector plate through the narrow gaps between the radiator fins and all the U-shaped radiators between the radiator fins. The openings between the right and left sides of the row fins and the openings surrounded by the reflectors are used as hot air outlets. For the fan motor mounted heat exchange cover, the U-shaped radiator is first placed on the oil pipe, and the U-shaped radiator is tapped and fixed with a stopper screw at a position exceeding the center of the oil pipe diameter, and the lower end of the U pipe is opened. The part is simply sandwiched between the lower oil pipes. The U-pipe is less costly than sheet metal processing, has a curved surface that hardly generates turbulent warm air flow, generates little noise, and is quiet enough to not make you conscious of the wind. Both processing and assembly are low-cost and high-performance. The problem is that although strength is not required, it is difficult to bend thin aluminum pipes. The U-pipe has a curved surface and has little resistance to the air flow generated by the fan.It recovers the room temperature lost by opening the door and window, and the room temperature rises quickly.It warms up quickly.

The heat exchange and direct heat radiation effect of the heating front are unexpected results.

The direct radiation effect of the U-shaped radiator is that the curved surface of the U tube on the heating side has a circular cross section and the outer peripheral area is a radiation surface, and the heat is directly transmitted regardless of the air flow. Remarkable and ideal heat exchange is achieved in all circumferential directions, and after passing through the heat exchange cover and splitting into two, the main airflow converges in the lower oil pipe, and heat is recovered in the straight pipe section of the U pipe directly below the central oil pipe. The function contributes to the temperature rise, and the rapid heat exchange promotion of the fan motor realizes quick warming. When the outside temperature is 10°C, it takes 7 minutes to send warm air to 17°C, and the power consumption is halved. The noise generated by the motor is greatly reduced by the sheet metal radiator, which acts as a silencer and contributes to the damping effect of the wind. At low speed, the heat exchange function of the fan is reduced, but the wide area of the U tube surface receives radiant heat, and the open part is only at the bottom end. The heat exchange radiator that promotes the heat storage effect and continues the heating effect is easy to assemble and low cost. The entire heating side is an ideal surface for radiating heat, and the convergence of air currents further enhances the heating effect.
