Description

[Detailed description of the invention] The present invention is a heating device, more specifically, a plurality of heating elements running vertically are arranged side by side on the left and right, and each heating element has a suction opening at the lower end and a discharge opening at the upper end. The present invention relates to a heating device that is surrounded by a heat dissipation pipe over almost the entire length from the top and bottom, and in which air is taken in from an inlet, passes through the heat dissipation pipe, and is heated, and then sent out from a discharge port by an upward flow.

As shown in FIG. 1, this type of conventional heating device fills a working fluid 8 in a finch tube 18 that has a large number of radiation fins 17 on its outer periphery and runs in the horizontal direction. Heat was extracted from the heat dissipation fins 17 by heating. For this reason, the height of the housing 16 cannot be increased, the draft effect is small, and the wind speed sent out from the housing 16 is low, resulting in a small amount of air. That is, as shown in FIG. 2, the heated air immediately moves upwards in the room 19, resulting in a large temperature difference between the upper and lower parts of the room 19.

The present invention was developed in view of the above-mentioned problems, and its main purpose is to increase the draft effect and increase the amount of air blown. Its purpose is to reduce the temperature difference between the top and bottom of the room, and its other purpose is to quickly heat the room.

Hereinafter, embodiments of the present invention will be described based on the drawings. In the heating device according to the present invention, a plurality of heating elements 1 running vertically are arranged side by side on the left and right, and each heating element 1 is connected to a plurality of heat radiation pipes 4 each having a suction port 2 at the bottom end and a discharge port 3 at the top end. It is a device that is surrounded by almost the entire length of the upper and lower sides, and in which air taken in from the suction port 2 and passed through the heat dissipation tube 4 is heated and then sent out from the discharge port 3 by an upward flow. The part is in close contact with a part of the inner peripheral surface of the heat dissipation tube 4, and in the part where the heat generating element 1 and the heat dissipation tube 4 are not in close contact, a plurality of pores 5 that penetrate inside and outside of the heat dissipation tube 4 are formed above and below, and the pores 5 are for heat dissipation. The opening area becomes larger toward the bottom of the tube 4. This embodiment shows an example in which the heating element 1 is a heat panel. As shown in FIGS. 4 to 6, a plurality of tubes 6 running vertically are arranged side by side on the left and right, the upper end of each tube 6 is closed, and the lower end of each tube 6 is one tube running left and right. It communicates with the liquid reservoir pipe 7. A working fluid 8 such as water, ammonia, or fluorocarbon is sealed in the liquid reservoir tube 7, and a sheathed heater 9 is immersed in the working fluid 8. The inside of each tube 6 is a vacuum, and when the working fluid 8 is heated by the sheathed heater 9, the evaporated working fluid 8 moves above the tube 6 and releases latent heat at the top of the tube 6. The liquid is condensed and falls into the liquid storage tube 7 by gravity, repeating the cycle and carrying the heat to the upper part of the tube body 6 at a high speed. Thereby, the tube body 6 is heated to a substantially uniform temperature from the lower end to the upper end. Each tube body 6 is connected by a connecting fin 10. The tube body 6 and the connecting fins 10 are formed by fixing two steel plates from the front and back. Heat dissipation tubes 4 are fixed to the outer surface of the heat panel 1 thus formed. The heat dissipation tube 4 is constructed by fixing a pair of heat dissipation plates 11 made of a good heat conductor such as copper or aluminum in a corrugated shape along the left and right directions to the front and rear surfaces of the heat panel 1.
It is formed around. The heat dissipation tube 4 has an elliptical cross section that is long in the front and back, and the conduit 6 of the heat panel 1 and the heat dissipation tube 4 are in close contact with each other at both left and right ends.
They are separated at both the front and rear ends. Therefore, conduit 6
A flow path 12 is provided between the front and rear surfaces of the radiator tube 4 and the front and rear surfaces of the heat dissipation tube 4.
is formed. The heat radiation pipe 4 and the pipe line 6 have approximately the same length in the vertical direction, and the flow path 12 is formed between the suction port 2 that opens at the bottom end of the heat radiation pipe 4 and the discharge port 3 that opens at the top end of the heat radiation pipe 4. Ru. A pair of heat sinks 1 are provided at positions corresponding to the connecting fins 10 of the heat panel 1.
1 in close contact with the front and back of heat panel 1,
A sub-radiator tube 13 having a diameter smaller than that of the heat-radiating tube 4 and running vertically is formed. This sub-radiator tube 13 is also open at both upper and lower ends.

By the way, in the portion of the heat dissipation tube 4 that does not come into contact with the tube body 6, as shown in FIG. 3, a large number of air holes 5 that penetrate inside and outside of the flow path 12 are formed along the top and bottom. Each pore 5 has an opening area that gradually decreases from the bottom to the top, and the air passing through the flow path 12 comes into contact with a lot of external air below the heat dissipation tube 4 and is hindered from moving, while above it. It has become easier to move around. That is, when the sheathed heater 9 is operated and the heat panel 1 is heated, air enters the flow path 12 from the suction port 2 at the lower end of the heat radiator 4, is heated, and is sent to the discharge port 3 by an upward flow. However, at this time, the rising speed of the air is slow below the heat dissipation tube 4 and becomes faster as it moves upward. In addition, a large amount of air can be taken into the flow path 12 from below through the pores 5, and the air taken in from the outlet 3 is sent out, so the wind speed of the air sent out from the outlet 3 is increased. It can send out a large amount of air quickly.

The apparatus constructed as described above is housed in a housing 16 having an intake port 14 at the lower end and an outlet port 15 at the upper end, as shown in FIG. 5, and is used for indoor heating.

As mentioned above, the present invention surrounds the heating element running vertically with a heat radiation tube with an inlet opening at the lower end and a discharge opening at the upper end, and makes the heating element and a part of the radiation tube closely contact each other. A large number of pores are formed in the vertical direction in the close contact area, and the lower the pores, the larger the opening area, and the air taken in from the suction port is heated and sent out from the discharge port by an upward flow, so the vertical length is reduced. It has the advantage of being able to take out a large amount of warm air due to the large draft effect and large air flow.As a result, the room can be heated quickly and the upper part of the room can be heated. This has the advantage that the temperature difference between the upper and lower parts can be reduced.
