    • PROBLEM TO BE SOLVED: To provide a hydrogen storage tank capable of suppressing deformation and breakage of a heat exchanger even if bulk density is reduced due to expansion and pulverization of a hydrogen storing alloy. SOLUTION: This hydrogen storage tank 11 incorporates the hydrogen storing alloy (MH) and the heat exchanger 13. The heat exchanger 13 is provided with a plurality of heat transfer fins 26, 27 joined with a heat medium pipe 20. A space between the adjacent heat transfer fins 26 and 27 is divided into a plurality of regions 28 by the heat transfer fin 26. MH powder 29 is filled into the regions 28 except a part of the regions, and the region in which MH powder 29 is not filled constitutes an absorption part 30 deformed by action force when the hydrogen storing alloy expand to absorb action force of expansion. The heat transfer fin 26 constitutes a sedimentation regulation means for regulating travel of the MH powder 29 in the direction of sedimentation while the hydrogen storage tank 11 is used.

    • PURPOSE:To pevent an unstable flow condition from being generated and prevent troubles such as repeated thermal stress from being generated, by inclining a heat-transmitting pipe downwards along a flow in the pipe, in a multi- pipe type heat exchanger. CONSTITUTION:A vapor introduced into an upper leg part 6A of a pipe group 6 is passed through an U-bend part 6B, and exchanges heat while flowing in a lower leg part 6C. The lower leg part 6C is inclined downwards toward a tube plate 3 at an angle of inclination theta, whereby a condensate collected in the lower leg part 6C is promoted in flowing toward an outlet chamber, so that it is prevented from stagnating in the part 6C or flowing back under minute vibrations in pressure. Accordingly, the condensate constantly flow stably, and no variation is induced in pressure or temperature due to disturbance in the flow. It is preferable to set the angle of inclination theta in the range of 0.2 deg.-0.3 deg., from a practical point of view.
    • 目的:为了防止产生不稳定的流动状况,通过在多管式热交换器中沿着管中的流动向下倾斜传热管,防止产生反复热应力等问题。 构成:导入管组6的上腿部6A的蒸汽通过U形弯曲部6B,在小腿部6C流动的同时进行热交换。 小腿部6C以倾斜角度θ朝向管板3向下倾斜,从而促进收集在小腿部6C中的冷凝物朝向出口室流动,从而防止其停留在部分6C中 或在压力微小的振动下回流。 因此,冷凝物恒定地稳定地流动,并且由于流动中的干扰而不会在压力或温度下引起变化。 从实用的观点出发,优选将倾角θ设定在0.2度-0.3度的范围内。
