One of adjacent edges 4a, 4b on opposite sides bonded by the division line 4 is displaced with respect to the other, and the surface of the heat reception plate 2 and at least parts of the adjacent edges 4a, 4b of the division lines 4 are brought into contact with each other parallely or in the state with any interval. A fluid discharged from supply means 6 of a received heat medium fluid adheres to the heat reception plate 2 and flows down along the same, and a remaining fluid dropped onto a dish surface 7 of the rectifier plate 1 also flows down on the dish surface and flows around the edge 3 of the rectifier plate. In such a manner. the fluid passes through a gap 8 formed with a substantially flat thin space constructed between the heat reception plate 2 and individual tongue-shaped pieces 5 to undergo a laterally flattened rectification action.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an improvement of a downflow collector.
In particular, it relates to improvement of the rectifying means used in the downflow collector.

[0002]

2. Description of the Related Art A technique is known in which a rectifying means having a large number of contacts is applied to the surface of a heat receiving plate to rectify the water passing through the contacts and spread it on the heat receiving surface. Various types of such rectifying means have been proposed, and there are various types of contacts.

[0003]

What can be said in common with the conventional rectifying means is that the structure is relatively complicated or there is a tendency to rely on craftsmanship processing techniques, which makes mass production difficult and expensive. There was a flaw. Further, it is required to exhibit stable rectification performance even when the flow rate is small. There is a need for a rectifying means which has a simple structure, is suitable for mass production, is inexpensive, and exhibits stable performance.

[0004]

The rectifying means of the present invention comprises a contactor of a type different from the conventional one. These contacts are provided along the edge on the side in contact with the heat receiving plate in the direction intersecting with the edge. The contactor is constituted by at least a part of side edges of a large number of dividing lines provided in a direction intersecting with the edge. The side edges of these contacts are arranged in parallel along the edges of the elastically deformable plate-shaped material.

As the plate material, for example, a metal plate such as a stainless thin plate or a plastic plate such as a polycarbonate plate can be used.

If necessary, a series of dividing lines may be sandwiched between the plate-shaped materials to form a boundary line at appropriate intervals. These boundary lines divide the plate material into a plurality of parts, and each part can be deformed independently of the other part.

[0007]

With the configuration as described above, each contact is pressed against the surface of the heat receiving plate by the elasticity of the plate material. By this pressing, at least a part of the side edges of the dividing line is brought into contact with the surface of the heat receiving plate substantially, and the other side edge adjacent to the contacted side edge forms a gap with the heat receiving plate. However, the heat receiving medium liquid passing through the gap is rectified so as to spread over the width of the gap.

Further, the respective portions partitioned by the boundary line are pressed against the surface of the heat receiving plate independently from the other portions by the elasticity of the plate material. Due to this pressing, the edges of the various parts fit well to the surface of the heat receiving plate. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated rectifying means 1a, 1b, 1c are provided with a large number of dividing lines 4 along an edge 3 on the side contacting the heat receiving plate 2 in a direction intersecting the edge. 1, 3, and 5 are partial perspective views showing specific examples of the rectifying means 1a, 1b, and 1c, and FIGS. 2, 4, and 6 are partial plan views of these rectifying means. .

Rectifying means 1a, 1b shown in FIGS. 3 and 5.
In the above, a plurality of dividing lines 4 are sandwiched and proper boundaries are provided to form boundary lines 9, and the boundary lines 9 divide the rectifying means 1 into a plurality of portions 10.

The side edges 4 on both sides adjacent to each other are separated by a dividing line 4 provided along the edge 3 on the side in contact with the heat receiving plate 2.
One of a and 4b is displaced from the other.

FIG. 7 shows a state in which the edge 3 of the straightening plate is in contact with the back surface of the heat receiving plate 2 due to the elasticity of the plate material. The edge 3 is pressed against the surface of the heat receiving plate by the elasticity of the plate material. Due to this pressing action, one side edge 4a of the parting line 4 practically contacts along the surface of the heat receiving plate over a certain range. The other side edge 4b adjacent to the contacting side edge 4a is deviated from the side edge 4a, and each tongue-shaped piece 5 separated by the dividing line 4 forms a gap between the side edge 4a and the heat receiving plate 2. There is.

A part of the liquid discharged from the heat receiving medium liquid supply means 6 toward the heat receiving plate 2 adheres to the heat receiving plate and flows down, and the remaining liquid dropped on the plate surface 7 of the straightening plate 1 is also the same. As it flows down on the plate surface, both liquids pass through the edge 3 of the straightening vane. In this way, the liquid passes through the gap 8 formed between the heat receiving plate 2 and each of the tongue-shaped pieces 5 and formed of a substantially flat thin space, and is subjected to the rectifying action of being spread horizontally.

8 and 9 are enlarged perspective views showing an example of the structure of a tongue piece provided on the edge 3 of the rectifying means 1a, 1b or 1c.

The left side 4b of the tongue 5 in FIG. 8 is slightly shifted downward with respect to the right side 4a, and the tongue 5 in FIG. 9 is staggered vertically.

Each of the tongue-shaped pieces may be configured such that the plate material is completely sheared along the dividing line, or at least a part of the tongue-shaped piece is left in the middle of shearing to form a step.

In the examples shown in FIGS. 1, 2, 3, and 4, the tongue is formed relatively finely, and in the examples shown in FIGS. 5 and 6, the tongue is formed relatively coarsely. ing.

The plate thickness of the plate-shaped material can be appropriately selected from a plate thickness of about 0.1 mm to a plate thickness of several mm.
The opposite edge of the rectifying plate is provided with the liquid supply means 6,
It can be fixed to the upper end of the heat receiving plate, the upper edge of the heat collector, or the bottom plate.

[0019]

By adopting the above-mentioned constitution, the rectifying means can be constituted by one plate-shaped material, the processing can be easily performed, and the cost can be reduced by mass production.

At the same time, it is convenient for a sealed downflow collector which can provide constant quality and cannot be adjusted by visual observation.

By adopting such a constitution, there is an advantage that a very large number of contacts can be applied to the heat receiving plate surface for fine rectification, and the rectification action does not change much depending on the flow rate.

Further, in the example in which the structure in which the boundary line 9 is installed is adopted, even if wavy uneven deformation occurs on the surface of the heat receiving plate (in the case where the heat receiving plate is made of metal such as stainless steel, it is accompanied by assembly). There is a plane error in the material, and a considerable amount of expansion and contraction deformation occurs due to temperature change during heat collection) The plate surface of each part 10 is deformed independently from the plate surface of other parts. In addition, since the dividing lines are arranged side by side, the edge becomes relatively flexible, and the edge can be accurately aligned with the surface of the heat receiving plate.
