Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure of a header that relays a plurality of inflow conduits and a plurality of delivery conduits, and particularly, a fluid flowing into the header is heated to a uniform temperature. It will be distributed at.

[Prior Art] As shown in FIG. 4, a conventional header 10 includes a plurality of inflow conduits 11 and a plurality of distribution conduits that are piped from a plurality of refrigerators and the like.
Used to relay 12 and. For this reason, the fluids that have flowed in from the plurality of inflow pipes are once combined in the header and then simply distributed by the plurality of delivery pipes.

[Problems to be solved by the invention] In the conventional header, a part of a plurality of refrigerators is stopped,
As a result, the fluid does not flow from a part of the plurality of inflow pipes, so that the temperature of the fluid distributed from the plurality of delivery pipes is not uniform. For this reason, when distributing a fluid with a uniform temperature, it was necessary to perform flow rate control and temperature control using a complicated external device, which increased piping equipment costs and was difficult to maintain. There was a problem that it took a lot of trouble.

This invention is to solve these problems, by mixing the fluid flowing into the header with a mixing plate,
An object of the present invention is to provide a header structure that makes the temperature and the like of the fluid distributed from the distribution pipe uniform.

[Means for Solving the Problems] The header structure of the present invention is a header that relays a plurality of inflow conduits and a plurality of delivery conduits, and is provided inside a header that is a boundary between the inflow conduit side and the distribution conduit side. It is characterized by installing a mixed flow plate.

Here, it is preferable that the mixed flow plate is formed of a spiral strip along the inner wall of the header, and a cutout portion for draining water is provided at the central top of the mixed flow plate.

The mixed flow plate consists of two semi-circular plates in contact with the inner wall of the header. Each semi-circular plate has a notch for draining water at the apex of its arc, and the semi-circular plate is installed at an appropriate interval in the flow direction in the header. You may use what does.

[Operation] In the header structure of the above means, since the mixed flow plate is provided inside the header, the fluid that has flowed into the header from the plurality of inflow pipes must pass through the mixed flow plate and a plurality of delivery pipes are provided. Distributed to the road. Therefore, the fluid passing through the mixed flow plate is sufficiently agitated, mixed, and distributed to the respective distribution pipes only by the flow force and the form of the mixed flow plate. Therefore, for example, even when some of the refrigerators are stopped, the uniformly mixed fluid is distributed to each distribution pipe line.

[Embodiment] A first embodiment according to the present invention will be described with reference to FIGS. 1 and 2.

The header 1 is configured by providing a pipe whose both ends are closed with a plurality of inlets and outlets. In this embodiment, the header 1
There were two inlets and five outlets. The two refrigerators and the two inlets of the header 1 are separately provided by the inflow pipes 2a and 2b. Then, the distribution pipes 3a, 3b, 3c, 3d, 3e are connected to the five distribution outlets, respectively. Further, the inside of the header 1 has a structure in which a mixed flow plate 4 to be described later is installed in a portion corresponding to a boundary between the inflow conduit side and the distribution conduit side.

As shown in FIG. 2, the mixed flow plate 4 installed inside the header 1 is formed by pressing a steel plate in an annular shape to form a strip, cutting a part of the strip and winding the strip. Is a spiral shape, and a notch 5 for draining water is further provided in the central outer peripheral portion thereof. When the mixed flow plate 4 is inserted into the header 1, the mixed flow plate 4 is fixed so that its outer peripheral portion contacts the inner wall of the header.

Next, the header structure of the second embodiment will be described with reference to FIG.

The header 1'of this embodiment is used by connecting a plurality of inflow pipes and distribution pipes, as in the above-described embodiment.
In the internal structure of this header 1 ', two semi-circular plates 6 to be described later are provided at the boundary between the inflow conduit side and the distribution conduit side.
The structure is such that a mixed flow plate consisting of a and 6b is installed.

The semi-circular plates 6a, 6b are formed by cutting a disc-shaped steel plate into two parts and providing a water drainage notch 7 at the top of the arc. These semi-circular plates 6a, 6b are provided so that their arc portions are in contact with the inner peripheral surface of the header, and further both semi-circular plates 6a, 6b are provided with an appropriate interval in the flow channel direction in the header and in the flow channel direction. It is fixed vertically and opposite to each other. Therefore, the two semi-circular plates 6a, 6b mounted inside the header
Since the fluid flowing into the header is agitated by the mixed flow plate consisting of, the uniformly mixed fluid is distributed to each distribution pipe.

[Advantages of the Invention] In the header structure of the present invention, since the header is provided with the mixed flow plate, the fluids flowing into the header from the plurality of inflow conduits are mixed to obtain a plurality of fluids having a uniform temperature. Can be distributed to distribution pipes.

Therefore, even if some of the refrigerators installed outside are stopped and cannot flow in from a part of the inflow pipe, the inflowing fluids are mixed in the header, so that fluids with a uniform temperature are always delivered. it can. Therefore, unlike the conventional case, an external device such as a flow rate control or a temperature control is not required, and the equipment cost and the labor for maintaining this are saved.
