Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called heat exchanger using an exchange medium and a medium to be exchanged.

FIG. 1 is a partial sectional view showing a conventional example.

In the figure, 1 is a casing having an inlet 1a and an outlet 1b for an exchange medium (for example, water), 2 is a fixed partition plate attached to one end of the casing 1 together with a first header (described later) by bolts 3, and 4 is a movable partition plate that is slidably fitted to the inner wall surface of the other end of the casing 1 via an 01J ring 5, and the exchange medium is placed in the exchange chamber A formed by the ground planes 1 and 2°4. It will flow through.

Reference numeral 6 denotes a plurality of pipes serving as medium passages whose respective ends penetrate through the fixed and movable partition plates 2.4 and are fixed to each other;
Reference numerals 7 and 8 denote first or second headers each having an injection lower a or a discharge port 8a for the medium to be exchanged (for example, oil), and the first header 7, as mentioned earlier, sand-winches the fixed partition plate 2. The second header 8 is fixed directly to the other end of the casing 1 with a bolt 9.

Here, the distribution chamber B formed by the first header 7 and the fixed partition plate 2 is for distributing the medium to be exchanged into the plurality of vibrators, respectively, and the second header 8 and the movable partition plate The collection chamber C formed by 4 is for collecting exchanged media from a plurality of vibrators and guiding them to the discharge port 8a.

In addition, 10 to 12 are O-rings as sealing members.

However, this conventional type has the following drawbacks.

That is, one of the partition plates constituting the exchange chamber A is made into a movable partition plate 4 in order to prevent thermal stress from being applied to the vibro.

However, due to the thermal expansion of the vibro, the O-ring 5 sealing the movable partition plate 4 and the casing 1 is connected to the inner peripheral surface of the casing 1 via the O-ring 5. Deterioration occurs due to displacement.

Since it is easily damaged, when the O-ring 5 deteriorates or is damaged, there is a situation where the exchange medium and the medium to be exchanged are mixed together.

In particular, if water, which is used as an exchange medium, mixes with oil, which is used as an exchange medium, if this oil is used for lubricating equipment, etc., there will be problems such as poor lubrication.

Furthermore, since this mixed accident belongs to an internal accident that cannot be directly seen from the outside, it is very difficult to detect it, which places an excessive burden on maintenance and inspections.

Another problem with the conventional type is that the O-ring must be made of a material that can withstand both media.

In view of the above points, the present invention prevents so-called mixing accidents between the exchanged medium and the exchanged medium, easily detects medium leakage due to O-ring deterioration, and can withstand a single OIJ song medium. The present invention provides a heat exchanger that can be made of different materials.

The present invention will be explained in detail below using the drawings. FIG. 2 is a partially sectional view showing an embodiment of the present invention.

In the figure, the same parts as in Figure 1 are marked with the same symbols.
The difference is that the second header 8' is fixed by bolts 13 to the outer wall surface of the movable partition plate 4 instead of the casing 1 via the OIJ ring 12, and the outer peripheral surface of the second header 8' is fixed to the outer wall surface of the movable partition plate 4. It is located on the inner diameter side of the sliding portion 14 between the plate 4 and the casing 1.

However, since it is no longer necessary to bolt the second header 8' to the end of the casing 1, the outer periphery of the end of the casing 1' on the second header 8' side is flat, as shown in the figure. It may also be in the form of

However, the function of the second header 8', together with the movable partition plate 4, forming a collection chamber C for the medium to be exchanged, and for sending the medium to be exchanged to the outside from the discharge port 8a' provided in the center thereof has been limited to conventional methods. It is similar to

The dynamics of this embodiment is almost the same as the conventional one, but to briefly describe it, the medium to be exchanged is injected from the injection lower a of the first header 7, passes through the distribution chamber B, and is filled with the exchange medium. A predetermined heat exchange is performed through a plurality of vibros arranged in the exchange chamber A, and at that time, the casing 1
The expansion and contraction caused by the thermal expansion chamber of the vibro and the vibro are absorbed by the interlocking movement of the movable partition plate 4 and the second header 8' attached thereto, and the medium to be exchanged coming out of the vibro is collected in the collecting chamber d and The liquid is led to the outside from the outlet 88' of the second head 8'.

Note that the partition plate on the -1 distribution chamber B side may have a movable partition plate structure, and in this case, the first ivy 7 is fixed to this movable partition plate.

In addition, there is no reason why the header on the fixed partition plate side must be fixed to the end of the casing together with the fixed partition plate, and the header is attached to the outer wall of the fixed partition plate in the same way as the header on the movable partition plate side. It may be something that sticks.

As explained above, according to the present invention, the header forming the exchange medium collection chamber or the distribution chamber is moved between the movable partition plates so that the outer peripheral surface thereof is located on the inner diameter side of the movable partition plate-casing sliding surface. Since it is fixed to the outer wall surface, firstly, even if the O-ring is damaged or deteriorated, so-called mixing accidents will not occur.
Therefore, there is no inconvenience caused by mixing both media.

Secondly, since deterioration of the O-ring can be quickly and easily detected by leakage of (exchange) medium from that part to the outside, maintenance and inspection can be simplified or automated.

Third, since the O-ring only contacts a single medium,
It has various excellent effects such as greater freedom in selecting materials.
