Description

この発明は、多数のプレート（伝熱板）を積層して形成するプレート式熱交換器に関するものである。   The present invention relates to a plate heat exchanger formed by laminating a large number of plates (heat transfer plates).

加熱装置や冷却装置等に用いられるプレート式熱交換器は、金属板のプレス加工で波型や半球殻型等の連続する凹凸面を形成した伝熱板を多層に重ね、伝熱板と伝熱板との間に狭い間隔の流体の流通層を形成し、液−液、液−ガスの２種類の流体を流通層に交互に流通させて熱交換を行うものである。一般に、交互に重ねる伝熱板は異なる種類が用いられるが、伝熱板を９０度回転させて重ね、１枚のプレートで製作する構造のプレート式熱交換器も提案されている（特許文献１参照）。
特開２０００−１６１８７７号公報 Plate type heat exchangers used for heating and cooling devices, etc., are laminated with multiple heat transfer plates that have corrugated surfaces such as corrugated or hemispherical shells formed by pressing a metal plate, and the heat transfer plate and the heat transfer plate. A fluid circulation layer with a narrow interval is formed between the heat plate and two types of fluids of liquid-liquid and liquid-gas are alternately circulated through the circulation layer for heat exchange. Generally, different types of heat transfer plates are alternately stacked, but a plate heat exchanger having a structure in which the heat transfer plates are rotated 90 degrees and stacked to produce a single plate has also been proposed (Patent Document 1). reference).
JP 2000-161877 A

一方、燃料電池装置等に用いられる熱交換器は、熱交換を行う液体（純水）が極めて少流量で、小型で高い熱効率のものが求められ、熱効率の向上には、伝熱面積の増大とともに、流通路の開口面積を小さくして流速の高速化を図る手段等が必要とされる。従来構造のプレート式熱交換器は、小型・薄型化に制限があるとともに、こうした性能要求に十分に対応できないものである。   On the other hand, heat exchangers used in fuel cell devices and the like require a liquid (pure water) for heat exchange with a very small flow rate, a small size and high thermal efficiency. To improve thermal efficiency, the heat transfer area is increased. In addition, a means for reducing the opening area of the flow passage and increasing the flow velocity is required. Conventional plate heat exchangers are limited in size and thickness, and cannot sufficiently meet such performance requirements.

この発明は、新規構造のプレート式熱交換器を提案し、これらの課題を解決することを目的とするもので、小型・薄型に製作されて熱効率に優れ、特に少流量の流体の熱交換に適合するプレート式熱交換器を提案するものである。   The present invention proposes a plate-type heat exchanger with a new structure and aims to solve these problems. It is manufactured in a small and thin shape, has excellent thermal efficiency, and is particularly suitable for heat exchange of a low flow rate fluid. A suitable plate heat exchanger is proposed.

こうした目的を達成するため、この発明のプレート式熱交換器は、プレート１０に所定パターンの開孔列１２を形成し、２枚のプレート１０を開孔列１２を交差させて重ねてプレートセット１５とし、四隅に連通孔２１を開孔した隔壁プレート２０とプレートセット１５を交互に積層し、隔壁プレート２０で区画された流体の流通層を形成し、各流通層を上下の一層を隔てた流通層と連通させたものである。   In order to achieve these objects, the plate heat exchanger according to the present invention forms a predetermined pattern of aperture rows 12 on the plate 10, and stacks two plates 10 with the aperture rows 12 intersecting to form a plate set 15. The partition plate 20 and the plate set 15 having the communication holes 21 at the four corners are alternately laminated to form a fluid circulation layer partitioned by the partition plate 20, and each circulation layer is separated from the upper and lower layers. Communicated with the layer.

また、請求項２に記載のプレート式熱交換器は、開孔列１２をくの字状のパターンに形成し、一方のプレート１０を１８０度回転させて重ねてプレートセット１５を形成し、表裏を順次反転した状態でプレートセット１５を交互に積層するものである。   The plate heat exchanger according to claim 2 is configured such that the aperture row 12 is formed in a U-shaped pattern, and one plate 10 is rotated 180 degrees to overlap to form a plate set 15. In this state, the plate sets 15 are alternately stacked.

この発明の熱交換器は、隔壁プレート２０で区画された流体の流通層を上下の一層を隔てた流通層と連通させたので、一方の流体と他方の流体が流通層を交互に流通し、隔壁プレート２０を伝熱面として熱交換が行われ、多層に積層した隔壁プレート２０により伝熱面積の増大が図られる。また、２枚重ねのプレートセット１５で流体の流通層が形成され、交差して重なる開孔列１２が流通路となり、交差した開孔列１２を縫うようにして流体が流通し、流通路の開口面積が小さくて流速の高速化が図られる。その結果、燃料電池装置等の少流量の流体の熱交換に用いて熱効率に極めて優れるものである。プレート１０の板厚が流通路の開口面積となるので、板厚の選定で流通路の開口面積（流通抵抗）を設定可能である。   In the heat exchanger of the present invention, the fluid circulation layer partitioned by the partition plate 20 is communicated with the circulation layer having the upper and lower layers separated, so that one fluid and the other fluid are alternately circulated in the circulation layer, Heat exchange is performed using the partition plate 20 as a heat transfer surface, and the heat transfer area is increased by the partition plate 20 stacked in multiple layers. In addition, a fluid circulation layer is formed by the two-layer plate set 15, and the opening row 12 that intersects and overlaps becomes a flow passage, and the fluid flows so as to sew the intersecting opening row 12, and the flow passage The opening area is small and the flow rate is increased. As a result, it is extremely excellent in thermal efficiency when used for heat exchange of a small flow rate fluid such as a fuel cell device. Since the plate thickness of the plate 10 is the opening area of the flow passage, the opening area (flow resistance) of the flow passage can be set by selecting the plate thickness.

また、従来のプレート式熱交換器と異なり、積層するプレート１０、２０はいずれも平板状で小型・薄型に製作され、組立作業性、生産性、接合性に優れるとともに、スキマ腐食の原因となる間隙が生じることがなく、耐久性にも優れるものである。   Further, unlike the conventional plate heat exchanger, the stacked plates 10 and 20 are both flat and manufactured in a small and thin shape, which is excellent in assembling workability, productivity and jointability, and causes skimmer corrosion. There are no gaps and the durability is excellent.

また、請求項２に記載したように、開孔列１２をくの字状のパターンに形成したプレート１０を用いることで、一種類のプレート１０でプレートセット１５が形成され、部品点数を削減して製作コストの低減を図ることができる。   In addition, as described in claim 2, by using the plate 10 in which the aperture row 12 is formed in a U-shaped pattern, the plate set 15 is formed by one type of plate 10 and the number of parts is reduced. Manufacturing costs can be reduced.
