JPS5847989A - Vessel for metal hydride - Google Patents

Abstract

PURPOSE:To impove the heat exchange efficiency of the titled vessel by a method wherein a doughnut type heat pipe itself which is used for the tranfer of heat is used as the vessel for the metal hydride at the same time and a hydrogen inlet and outlet pipe is provided at the central hollow section of the heat pipe. CONSTITUTION:The open ends of the doughnut type heat pipe are closed with covering plates 4a and 4b and the metal hydride 6 is packed into the central hollow section 5 of the heat pipe. Further, the hydrogen inlet and outlet pipe 8 povided with a changeover valve 7 is attached to the covering plate 4a and a porous pipe 9 is passed through the central hollow section 5 of the heat pipe in the axial direction in continuation with the pipe 8. The pipe 9 allows hydrogen to pass through the wall thereof although it does not allow the metal hydride 6 to do so. Thus, due to the fact that the heat pipe serves as the vessel for the metal hydride 6, it is possible to reduce a heat loss as sensible heat to the pressure resistant vessel and also it is possible to improve the heat exchange efficiency of the vessel since the sectional area of contact between the heat pipe and the metal hydride 6 is large.

Description

[Detailed Description of the Invention] This invention relates to a metal hydride container used in a livestock storage device,
More specifically, the present invention relates to a metal hydride container in which the central hollow part of a doughnut-shaped heat pipe is filled with a metal hydride to exchange heat with high efficiency.

Pupeng hydrogenated proboscis has the property of absorbing multiple waves of water, so its use as a water-based energy storage material has attracted attention, and since the heat of reaction during absorption and release of Mayu water cable is large, it has been used as a heat storage material. The use of heat storage *m or water cable storage 'Mi- using smoke hydrides is also attracting attention, allowing metal aqueous compounds to efficiently absorb heat and efficiently absorbing the heat generated from metal aqueous compounds. Figure 1 shows a conventional example of a metal hydride storage container, in which the removal and use of metal hydrides is an important factor.

This heat storage device is connected to a hydrogen inlet/outlet port 0 having a closed valve and a sintered alloy filter, and is connected to

One, the interrogation officer (36m, 36mm) has uLA 14 medium-4 with 1 light and fcM Chikya 4-ken with fins - noodles dried with tobaipu. In addition, the most important part of the heat pipe between hydrogenation and silent communication 4 is covered by the heat material.

At the time of heat build-up, heat is transferred from the M medium through a heat pipe to heat the hydrogen gas, and the nearly formed water is released by opening the S f-closing valve. etc. (without being violent) and accumulate power. At the time of discharge, open the on-off valve and transfer hydrogen from the aqueous pump to the aqueous compound container, and transfer the heated heat to the heat exchanger through the heat pipe wfJaI to heat the heating medium φ4. Take advantage of this heat. However, in such an i-direction, the contact Lfo product between the hydrogen nozzle of the vessel JI4 and the pressure-resistant capacity 4 of the metal-hydrogen-bond valley device is large. Therefore, 4il of this pressure-resistant valley 4! F: Inutenkura has a large amount of loss of Entsukuda, which is lost as Guoguo. In addition, the genus Mizumoto's proboscis absorbs and releases hydrogen gas, pulverizes it, and reduces its volume.
Hydrogenation with one liter of melting - 6 feet of heat exchange - one or a low temperature (bowman - rimoaguchi).

In order to eliminate such defects and fading, this invention was made by filling the middle part of the donut with water and boiling it over medium heat. +411

However, the degree of reduction in the above-mentioned surface area is much smaller, which is an advantage.
