Conventionally, as shown in FIG. 1, annular fins 3 are arranged in the axial direction in a casing 2 in which an air passage is formed, and a pipe 4 passes through the annular fins 3 and allows a fluid such as water to flow therein.
By rotating the rotating annular fin body 1 on which the side plates 5 and 5 are installed, the surrounding fluid such as air is made to flow in the direction of the white arrow, and the fluid such as water is made to flow through the pipe 4, thereby promoting heat exchange between the two fluids. There was a rotary heat exchanger to do.

From the perspective of a blower, such a rotary heat exchanger corresponds to a friction disk blower.

したがって風量■は環状フィン3の外径dの2乗に比例
し、環状フィン枚数に比例する環状フィン群の軸方向長
さtは、d/2以下であることが望ましいとされている
Therefore, it is said that the air volume (2) is proportional to the square of the outer diameter d of the annular fin 3, and that the axial length t of the annular fin group, which is proportional to the number of annular fins, is d/2 or less.

このようなことから、空気調和機として必要な風量を効

For this reason, in order to efficiently obtain the air volume necessary for an air conditioner, it is necessary to make the outer diameter d very large and the length t short.

However, if we look at such specifications from the perspective of a heat exchanger, since the length t is short, the entire length of the pipes through which fluid such as water flows, including the bends or bends (not shown) that connect the pipes 4, On the other hand, the length of the tube 4 used for heat exchange =
tX (number of pipes) becomes smaller, the amount of heat exchange per total pipe length becomes smaller, and the flow resistance of bends or bends is greater than that of straight pipes, so pumps that transport fluids such as water (Fig. Less power is required for the tubes 4 utilized for heat exchange, relative to the total power for (not shown).

したがって、熱交換器としての性能は著しく低下する。Therefore, the performance as a heat exchanger is significantly reduced.

一方、熱交換器としての観点からみれば、長さtを長く

On the other hand, from the viewpoint of a heat exchanger, it is desirable to increase the length t, that is, to increase the length of the tube 4 used for heat exchange.

However, if such specifications are adopted, the performance as a blower will deteriorate and the Q velocity distribution of the casing outlet (not shown) will deteriorate.

That is, when the annular fin body 1 with tf=d is rotated using the electric motor I to transport fluid such as air, the velocity distribution at the casing outlet (not shown) is uneven as shown in FIG. The closer the value is to 9, the faster the flow rate of fluid such as air is, and the further away from the suction port 9, the slower the flow rate.

Conventionally, in order to eliminate this drawback, there have been measures such as placing a fixed guide vane device 10 inside the annular fin body 1 as shown in FIGS. One possible method is to place an axial fan 11 at the suction port 9, which increases the air volume by increasing the pumping action.

Note that 12 is a bearing device. However, even though the air volume can be increased by the means proposed in this way, there is a drawback in that the air velocity distribution at the casing outlet is not improved at all.

This is because although an increase in the amount of air flowing into the annular fin body 1 is certainly observed, it increases at a uniform rate, so although the absolute amount of air amount can be obtained, there is a drawback that the state of the wind speed distribution does not change. was.

Although the performance as a blower is improved, when viewed as a heat exchanger, the wind speed distribution is poor, so heat exchange is not performed over the entire length of the tube 4, and the performance as a heat exchanger is not fully demonstrated.

Furthermore, when used as an air conditioner, the temperature distribution at the casing outlet (not shown) is poor, which has a drawback of having a very negative effect on the human body's sense of pleasure.

With the above configuration, when the rotating annular fin body 1 is rotated by the electric motor 7 to cause fluid such as air to flow in the direction of the white arrow, the portion A where the flow velocity is high is only the annular fin 3, as shown in FIG. So, the part B where the flow velocity is slow is the annular fin 3.
Then, the fluid such as air is transported to the casing outlet by the fluid guide device 13, and due to the increase in the pumping action of the blades of the fluid guide device 13, it is possible to increase the wind speed at the portion B where the flow velocity is low at the casing outlet. It is possible to obtain a uniform velocity distribution at the casing outlet, and also to increase the amount of air that has been insufficient due to the velocity distribution shown in FIG. 2.

Note that 15 is a side plate. As described above, in the rotary heat exchanger of the present invention, a fluid guiding device having a plurality of vanes and having a pumping action is arranged inside the rotating annular fin body so as to uniformize the velocity distribution at the casing outlet. By doing so, it is possible to achieve both a uniform speed distribution and an increase in air volume, improving the performance of the rotary heat exchanger as a blower.
Moreover, it has a very practical effect in improving the performance as a heat exchanger.
