Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a capacitor for an underwater vehicle used in a closed Rankine cycle propulsion system.

[Conventional technology]

Some propulsion systems for navigating underwater vehicles utilize the closed Rankine cycle shown in FIG. In other words, the oxidizer saturated vapor such as SF6 vaporized in the oxidizer tank 'pa is guided to the metal combustor (boiler) B,
The water in the evaporation section E of the boiler is made to react with an alkali metal such as Ll placed in the boiler, and the water in the evaporation section E of the boiler is turned into steam by the heat of the reaction, and the steam is used to drive the turbine T to propel the underwater vehicle.

The brackish water mixture, which is the exhaust gas of the turbine 'r, is condensed in a condenser C and supplied again to the evaporation section E of the boiler B by a pump P. The condenser of an underwater vehicle whose propulsion system is constructed using the Rose Trunkin cycle and uses water as the working fluid is constructed using the outer skin of the underwater vehicle, and during navigation. The steam is then condensed into water through heat exchange with external seawater W.

FIG. 5 is a perspective view showing a conventional capacitor for such an underwater vehicle. As shown in the figure, the capacitor of a conventional underwater vehicle is a capacitor of an underwater vehicle.
A method of manufacturing by forming the steam passage 05 into a single piece and drilling the steam passage 05 parallel to the axis using a drill.

Alternatively, although not shown, an inner cylinder and an outer cylinder are manufactured as the outer skin of an underwater vehicle, and a steam passage groove is formed between the two cylinders (after that, the two cylinders are fitted together to form a steam passage hole, etc.). In Fig. 5, the arrows indicate the direction of flow of steam or condensed water.

1. Problems to be solved by the invention/device] By the way, in the case of conventional capacitors for underwater vehicles.

, - Due to the processing accuracy of the manufacturing method of drilling the steam passage 05 in the cylindrical body 01 formed as a body object, the
However, there were also problems such as poor productivity because it was difficult to complete the capacitor due to limitations on the straightness of the drill.

Furthermore, in conventional condensers, regardless of the manufacturing method, the steam passage is formed as one continuous passage from the inlet to the outlet, so condensate (water) condenses from the steam in the middle of the passage and accumulates in the middle of the passage. There was also the problem that a liquid film was formed, which obstructed the passage of steam, resulting in a decrease in condensate performance. In addition, if the outer skin of an underwater vehicle is made by dividing into an inner cylinder and an outer cylinder, and a steam passage groove is formed between each cylinder, then nine cylinders are fitted together to form a steam passage, the crushing strength against external pressure is inevitably low. It also had some disadvantages, such as its small size and the inability to use it for ice-travelling vehicles that travel at great depths.

The present invention aims to solve such problems by dividing the condenser of an underwater vehicle into three parts in the longitudinal direction, and connecting a plurality of steam passage holes in the intermediate cylinder in the circumferential direction. The purpose of the present invention is to provide a capacitor for an underwater vehicle that has excellent workability, productivity, and condensing performance by providing a drain groove.

[Failure to solve the problem]

For this reason, the capacitor of the underwater vehicle of the present invention is.

an inlet cylinder and an outlet cylinder each having a cylindrical body and having a plurality of steam passages spaced apart in the circumferential direction and parallel to the axis; It is characterized by comprising an intermediate cylinder provided with a plurality of steam passages parallel to the axis, and a circumferential drain groove provided at both ends of the intermediate cylinder to communicate the plurality of steam passages.

[Effect]

According to the above-described capacitor for an underwater vehicle according to the present invention, by dividing the capacitor into parts, workability is improved and condensing performance is improved without being limited by the overall length of the capacitor. In addition, by providing a drain groove, water that is condensed on the upstream side of the groove is temporarily collected there, and then drained from the condenser through a specific steam passage, thereby preventing the formation of a liquid film of water in other steam passages. thwarted. Since it is still a single piece, it has high crushing strength against external pressure.

〔Example〕

A capacitor running at 31°C underwater as an embodiment of the present invention will be explained below with reference to the drawings. Fig. 1 is a perspective view showing the entire capacitor, Fig. 2 is a perspective view showing a divided capacitor, and Fig. 3 is an end view of the intermediate cylinder taken in the direction shown by the arrow T in FIG. 2, and FIG. 4 is a longitudinal sectional view taken in the direction IV-IV in FIG. 3.

In these figures, 1 is an artificial cylinder and 2 is an intermediate cylinder. Outlet cylinder 3
Together with this, it forms the outer skin of the underwater vehicle, and equipment such as propulsion equipment is placed inside it. Artificial cylinder 1. The intermediate cylindrical outlet cylinder 6 is provided with a large number of steam passages 4 and 5 which are drilled in the longitudinal direction of the cylinder and extend through both ends thereof. There are still drain grooves 6 on both end faces of the intermediate cylinder 2 that communicate in the circumferential direction.
, 7 are provided. The drain grooves 6 and 7 are provided in communication with the steam passages 4 and 5. And artificial cylinder 1. Intermediate cylinder 2. The outlet cylinders 3 are arranged as shown in FIG. 1, and the end faces of adjacent cylinders are welded together to form one capacitor. Of course, it is desirable to weld the inner surface as well to increase the crushing strength.

The capacitor manufactured in this manner is fitted into the parallel body of the underwater vehicle and forms a part of the body of the underwater vehicle.

The condenser of the underwater vehicle of this embodiment has such a configuration, so that the steam exhausted from the turbine T is
．． Intermediate cylinder 2. The steam flows as indicated by the arrows in the plurality of steam passages 4 and 5 that are opened parallel to the axial direction of the exit cylinder B, and condensation is completed by the time it reaches the outlet of the exit cylinder B. in the middle,
The condensate condensed on the upstream side of the drain collection groove 6.7 provided circumferentially on the end face of the intermediate cylinder 2 is collected in the groove 6.7 and is directed to a specific steam flow path, that is, the bottom steam passage 4.
It passes through the entire interior and flows to the exit side. Therefore, in other steam channels 5, the passages are closed by drain liquid films, especially in the intermediate cylinder 2. Closure of the steam passage in the outlet cylinder 3 is prevented, and no deterioration in condensing performance occurs.

Further, the crushing strength is significantly increased compared to the case where the capacitor is formed by a combination of an inner cylinder and an outer cylinder, and the drilling of the steam passage is easy, so that the machining accuracy can be improved. Furthermore, since the capacitor is manufactured by dividing it into three parts in the length direction, the length of the capacitor can be freely determined compared to conventional capacitors, which could not be made into long capacitors due to constraints on the straight-line movement of the drill. The water capacity can be increased and the efficiency of the propulsion system can be increased.

Although the embodiment shows a product divided into three parts, it goes without saying that the product may be manufactured by dividing it into three or more parts.

[Effects of inventions and ideas]

As described above, according to the capacitor for an underwater vehicle according to the present invention, a) workability and productivity can be improved by dividing the capacitor into parts.

B. It is now possible to create a drain groove in the middle of the steam passage, which prevents condensation in the middle of the steam passage.

The condensate performance is improved because the condensate drain is discharged through a specific passage.

First, the capacitor is integrated, increasing its crushing strength against external pressure.

This provides advantages such as:
