In a condensing heat exchanger, medium vapor comes into contact with a heat transfer surface that has been cooled to a low temperature, and the medium vapor is deprived of heat and condenses and adheres to it.The thicker the film of the condensed medium, the more It is better to make the thickness of the medium film as thin as possible since this will inhibit the condensation and adhesion of the medium vapor. Similarly, in the in-tube condensing heat exchanger, the thinner the thickness of the medium film condensed on the inner wall of the tube, the better the condensation efficiency.

このため、凝縮熱交換器では凝縮付着した媒体

Therefore, in a condensing heat exchanger, it is necessary to remove the condensed medium from the inner wall of the tube as quickly as possible.

In this known liquid drawing device, electrodes to which a voltage of 9000 V or more is applied are installed opposite to the wall surface on which the condensed medium adheres, with a slight gap (for example, about 2 mm), and the condensed medium is drawn toward the electrode. It is to be discharged.

(Problems to be Solved by the Invention) However, since the above-mentioned known electrode is made of a linear body such as an electric wire, the wire electrode is installed on the inner wall of a long tube with a small gap, or a large number of wire electrodes are It was very difficult to install wire electrodes along the inner wall of the tube. For this reason, conventionally, there has been no effective electrode structure for in-tube condensing heat exchangers.

Referring to FIGS. 1 and 2, the tube 1 is a condensing tube into which Freon vapor or the like is introduced, and the tube 1 is cooled from the outside or heat is radiated to the outside of the tube 1. Freon vapor condenses and adheres to the inner wall of the tube 1. An electrode 2 is inserted and fixed inside the tube 1. The electrode 2 has four radial blades 3 and has a cross-shaped cross section. The tips 3 1 of the radial vanes 3 face the inner wall of the tube 1 with a gap h of, for example, about 2 mm. A high voltage of, for example, about 9000V is applied between the electrode 2 and the tube 1. This voltage may be higher than that.

In this embodiment, the tube 1 is placed extending vertically, and the electrode 2 is inserted extending in the longitudinal direction of the tube 1. A groove 4 is provided in the side surface 3 2 of each blade 3 . The groove 4 slopes downward from the tip 3 1 of the blade 3 toward the radial center 3 3 of the blade 3. A plurality of grooves 4 are provided in the longitudinal direction of the electrode 2.

In the present invention configured as described above, when a high voltage is applied to the electrode 2, the medium condensed and adhered to the inner wall of the tube 1 is attracted to the tip 31 of the blade 3 as shown at P1 in the figure, and further As shown in P 2 , it flows down the groove 4 due to gravity. Then, it flows down the center part of the electrode 2 as shown in P 3 .

Furthermore, the blades may be spirally shaped in the longitudinal direction. If the feathers are straight and cross-shaped,
The tips of the blades face each other at the same position in the longitudinal direction of the inner wall of the pipe, and the condensed medium is attracted to a portion of the inner wall of the pipe.However, if the blades are shaped like this in a spiral, the tips of the blades will face the inner wall of the pipe. Since the condensed medium is not concentrated in one part, the condensed medium can be drawn out evenly.

Figures 3 and 4 show yet another embodiment of the invention in which the tube is placed horizontally.

As shown in the figure, if the blades 13 are formed into a spiral shape, the tube 11 can be placed horizontally. When the tube 11 is placed horizontally in this manner, the groove 4 required for the vertically placed tube shown in FIG. 2 is unnecessary.

That is, since the blade 13 having a cross-shaped cross section can be interpreted as a blade electrode having four V-shaped corners 14,
If this is a spiral, each corner 14 will turn as it advances in the longitudinal direction of the horizontally placed tube 11. Expressing this in terms of the cross section of the blade 13, the corner 141 shown in FIG. 4 gradually turns from upward to sideways, and then gradually downward, as if rotating in the direction of the arrow in the figure. Therefore, the liquid drawn out to the V-shaped corner 14 flows along the V-shaped corner 14 in the longitudinal direction of the tube 11 while being pushed by the flow of medium vapor, as shown in P4 in the figure, until the groove 14 is formed. It flows out to the bottom of the pipe 11 from the point facing downward. The liquid accumulated at the bottom of the tube 11 flows toward the end of the tube 11 through the gap between the inner wall of the tube 11 and the tip of the vane 13 due to gravity or the flow of medium vapor, and flows from the tube end. It is discharged outside the tube.

Further, since the vane electrode has higher manufacturing precision than a linear electrode, it is easier to maintain the gap h with the inner wall of the pipe at a predetermined value.

In the case where the tube is placed vertically, the blades are provided with grooves, and the liquid drawn through the grooves is guided to the center of the electrode, resulting in an even higher liquid drawing effect.
