JP3124850U - Sealing member for attaching the longitudinal baffle of the in-body piping heat exchanger - Google Patents

Abstract

As a seal member for attaching a longitudinal baffle in an in-body piping heat exchanger, it is not necessary to perform special processing on the longitudinal baffle itself and the longitudinal baffle for attaching to the side end of the longitudinal baffle. Providing products with low cost.
A web 16 having a groove 17 capable of being tightly fitted to a side end of a longitudinal baffle 12 and a flange 18 having an angled ridge 19 branching off from a side opposite to the groove opening of the web 16. The cross section provided with is made of a rubber mold 15 having a Y shape.

Description

  The present invention relates to an in-cylinder pipe (shell tube) type heat exchanger in which a pipe (including a U-shaped pipe extending through a U-shaped portion) extending in parallel with the long axis of the trunk is disposed in the trunk. In order to make the fluid flow in a U shape in the longitudinal direction in the cylinder, it is attached to both side ends of a longitudinal baffle (longitudinal baffle plate) that divides the interior of the cylinder along the long axis, The present invention relates to a seal member for sealing a gap.

  As this type of sealing member, as shown in FIG. 2, one side end is fixed to the side end of the longitudinal baffle 12 via a bolt 21, and the other end is elastically deformed to the inner surface of the barrel 11. A metal thin plate 20 that can come into contact in an arcuate bent state is commonly used (see, for example, Non-Patent Document 1).

Although the conventional sealing member made of the metal thin plate 20 has a good sealing function itself, it is necessary to form a bolt hole in itself and the longitudinal baffle 12 for attachment to the longitudinal baffle 12, and Since the thin plate 20 itself is also relatively expensive, there is a problem that the cost is high as a whole.

  In view of the above-mentioned cost problems found in conventional ones, the present invention eliminates the need for special processing on itself and the longitudinal baffle for attachment to the side end of the longitudinal baffle, and The main problem is to provide a sealing member that is low in cost.

  The sealing member according to the present invention includes a web (plate body) having a groove that can be tightly fitted to a side end portion of the longitudinal baffle, and a web anti-slip, as defined in claim 1 of the utility model registration claim. The cross section provided with a pair of flanges bifurcatingly extending from the groove opening side (groove bottom side) is a Y-shaped rubber mold (profile).

  In the sealing member according to the first aspect of the present invention, as described in the second aspect, it is desirable to attach a protrusion that can contact the inner surface of the barrel to the bifurcated sides of the pair of flanges.

  As for the ridge attached to the flange of the sealing member of the present invention according to claim 2, the ridge is preferably an acute angle chevron as described in claim 3.

  According to the sealing member according to the first aspect of the present invention, the attachment of the longitudinal baffle to the side end of the longitudinal baffle is easily performed through the insertion (fitting) of the web groove to the lateral end of the longitudinal baffle. In addition, since it is a rubber mold, it can be easily formed by molding, and its cost is low.

  Further, according to the configuration for attaching the protrusions on the flange according to claim 2, since the contact area with the inner surface portion of the cylinder is small, the resistance at the time of mounting on the cylinder is small, and the installation can be performed smoothly.

  Furthermore, according to the acute angle mountain configuration of the protrusion according to the third aspect, since the contact area with the inner surface of the trunk is minimized, the mounting on the trunk can be performed more smoothly.

  FIG. 1 shows a rubber plate-like mold material, which is a preferred embodiment of a sealing member according to the present invention, attached to a side end portion of a longitudinal baffle and mounted in a barrel, and brought into contact with an inner surface portion of the barrel. The rubber plate-like mold material 15 shows a web 16 with a groove 17 and a pair of flanges 18 branched from the side opposite to the groove opening (groove bottom) of the web 16. Each flange 18 is provided with a plurality of acute angle ridges 19 between the tip and the base on the bifurcated side.

  This rubber mold 15 has a pair of flanges 18 interposed at least through protrusions 19 at the front end in a state where the groove 17 of the web 16 is fitted to the side end of the longitudinal baffle 12 and sandwiched. In a state of elastic deformation with an expanded bifurcated angle caused by contact with the inner surface portion of the cylinder 11, the cylinder 11 is mounted while being slid into the cylinder 11, and finally, as shown in the drawing, the leading ends of both flanges 18 are projected from the section. It abuts against the inner surface of the barrel 11 via the strips 19 to make a desired sealed state therebetween.

  In addition, the sealing member of the present invention can be implemented in various forms, and is not limited to the illustrated form.

It is a cross-sectional view of the use condition of the preferred embodiment of the seal member concerning this device. It is a cross-sectional view of the use state of a conventional seal member.
