摘要： PROBLEM TO BE SOLVED: To inhibit generation of the internal pressure by solidification of a working fluid and to improve durability of a heat exchanger in a heat pipe type heat exchanger provided with inner fins.
SOLUTION: The lower end 8c of an inner fin 8 arranged in a heat pipe 3a is positioned above the top surface position F of a working fluid at the time of a liquid state. At the time the working fluid of a liquid state in the heat pipe 3a starts to solidify, the top surface of the working fluid does not contact the inner fin 8 therefore the heat transfer becomes slow and solidification of the top surface of the working fluid in the heat pipe 3a becomes slow. Accordingly, the volume of the liquid state working fluid confined in the inside of the solid state working fluid is decreased at the time the top face of the working fluid in the heat pipe 3a is solidified and blockaded, thereby generation of the internal pressure by solidification of the liquid state working fluid is inhibited.

摘要翻译：要解决的问题：通过设置有内翅片的热管式热交换器来抑制工作流体的凝固而产生内部压力并提高热交换器的耐久性。解决方案：布置在热管3a中的内翅片8的下端8c位于液态时工作流体的上表面位置F的上方。在热管3a中的液态工作流体开始凝固时，工作流体的顶面不接触内翅片8，因此传热变慢，工作流体顶面的凝固变得热管3a变慢。因此，在热管3a内的工作流体的顶面凝固封闭时，限制在固体工作流体内部的液态工作流体的体积减少，从而通过凝固产生内部压力的液态工作流体被抑制。版权所有（C）2008，JPO＆INPIT

摘要：【課題】流体の自励振動変位を伴い発熱体を冷却する冷却器であって、その発熱体と流体との間における熱伝達率の悪化を防止できる冷却器を提供する。【解決手段】第1発熱体121は、冷媒が冷却部空間242から加熱部空間241内へ流入する冷媒流れの方向DRinに対して第1発熱体121の発熱面121aが傾斜して対向するように配置されているので、加熱部空間241内へ流入する液体冷媒がその慣性により上記発熱面121aに押し付けられつつその発熱面121a上を移動することになる。そのため、第1発熱体121と冷媒との間における熱伝達率の悪化を防止することが可能である。例えば、液体冷媒が第1発熱体121の発熱面121aに押し付けられることによって、冷媒の沸騰による蒸気膜の形成が妨げられるので、第1発熱体121の発熱面121aと冷媒との間において膜沸騰に起因した熱伝達率の悪化を防止することが可能である。【選択図】図1
摘要翻译：要解决的问题：提供一种冷却器，其冷却发热体，同时涉及流体的自发振动位移，并且可以防止发热体和流体之间的传热系数的劣化。解决方案：由于第一发热体121被配置成使得发热体121的发热面121a相对于制冷剂从制冷剂流入加热部空间241的制冷剂流的方向DRin倾斜并相对冷却流入加热体空间241的液体制冷剂通过制冷剂的惯性被压在发热面121a上而在发热面121a上移动。结果，能够防止第一发热体121与制冷剂之间的传热系数的劣化。例如，由于液体制冷剂压靠发热体121的发热面121a而阻碍了由制冷剂的沸腾引起的蒸气膜的形成，所以由薄膜沸腾产生的传热系数的劣化能够防止第一发热体121的发热面121a与制冷剂之间的间隙。

摘要： PROBLEM TO BE SOLVED: To improve hydrogen-permeability in an exhaust-heat recovery device for discharging hydrogen-gas to the outside by utilizing a high hydrogen-permeability at high temperature of at least 500°C held by chromium-stainless steel.
SOLUTION: A heating part 2 placed in the inside of an exhaust pipe 10 is formed of a plurality of tubes 2a. An upper header-tank 7 connected to the upper ends of the tubes 2a is placed on the outside of the exhaust pipe 10. The periphery of the upper header-tank 7 is covered with heat insulating means 22, 23, the upper header-tank 7 is formed of a base material of chromium-stainless steel, and Ni-plated layers are formed on both inside and outside of the base material. Thus, when supply to the heating part 2 of the working fluid is stopped by a selector valve 6, the upper header-tank 7 is held at high temperature of at least 500°C by the heat-insulating means 22, 23, and hydrogen gas is discharged from the upper header-tank 7 to the outside. In this case, the Ni-plated layers on the inside and outside of the base material serves to accelerate the permeation of hydrogen.
