【考案が解決しょうとする課題】[Issues to be solved by the device]

従来の円形皿状プレートの積層体からなる熱交換器は弧状に流通するプレート 各部の流体が中心孔周縁に、より多く流通しがちである欠点があった。 また、流体の撹拌を促進するために多数の凸条をプレート平面に形成した熱交 換器においては、隣接するプレートでその凸条どうしが互いに交差し流体が網目 状に流通するため、内部の流体抵抗が高くなる欠点があった。流体の撹拌を充分 に行いつつ、且つ流体抵抗が小さく、流体の流通を円滑に行い得る熱交換器が望 まれていた。 The conventional heat exchanger composed of a laminated body of circular dish-shaped plates has a drawback in that the fluid in each part of the plate that circulates in an arc shape tends to circulate more in the periphery of the central hole. Further, in a heat exchanger in which a large number of ridges are formed on the plate plane in order to promote fluid agitation, the ridges intersect with each other in adjacent plates and the fluid flows in a mesh shape, so There was a drawback that the fluid resistance was high. There has been a demand for a heat exchanger that can sufficiently stir the fluid, has low fluid resistance, and can smoothly flow the fluid.

【考案の効果】[Effect of device]

本考案の熱交換器は、円形皿状プレートの各部を流体が弧状に流通するとき、 その内周部に偏りがちな流体を外周部に積極的に流通させ、熱交換を促進させ得 る。なぜならば、内周部付近を弧状に流通する流路はその流路長が短いが、波形 の波の周期も短いため、その分だけ抵抗が大となる。これに対して、外周部付近 を孤状に流通する流路はその流路長が長い分だけ、波長の波の周期も長くなるた め、その波形による抵抗が小となる。その結果、各部における流路の流路抵抗が 比較的均一になり、プレート各部における流体の流通を均一にし得る。しかも円 形皿状のプレートにおいて、隣接する夫々の波が進行方向に互いに同期している ため、積層型の熱交換器において、流体の流通抵抗を小さくし、且つ波形による 撹拌効果をもたらし、熱交換を促進し得る。 The heat exchanger of the present invention can promote heat exchange by positively circulating the fluid, which tends to be biased toward the inner peripheral portion, to the outer peripheral portion when the fluid flows in an arc shape through each portion of the circular dish plate. This is because the flow path that circulates in an arc around the inner circumference has a short flow path length, but the cycle of the wave of the waveform is also short, and therefore the resistance increases accordingly. On the other hand, the flow path that circulates around the outer peripheral portion in an arcuate manner has a longer flow path length, and therefore the cycle of the wave of the wavelength becomes longer, so that the resistance due to the waveform becomes smaller. As a result, the flow resistance of the flow path in each part becomes relatively uniform, and the fluid flow in each part of the plate can be made uniform. Moreover, in the circular plate, since the adjacent waves are synchronized with each other in the traveling direction, the flow resistance of the fluid is reduced in the stacked heat exchanger, and the stirring effect due to the corrugation is generated, Can facilitate exchange.
