Description
One, technical field:
The present invention relates to a kind of hydrogen-storage alloy reactor, specifically, relate to a kind of hydrogen-storage alloy reactor the powder sintered moulding of hydrogen-storage alloy.
Two, background technology:
Generally speaking, hydrogen be under high pressure conditions, be stored in high-pressure bottle by or be cooled to extremely low temperature and store with liquid condition.But because the density of hydrogen is very little, thus can be stored in the high-pressure bottle amounts of hydrogen seldom, thereby make the container volume of storage of hydrogen big, weight is also big, the inconvenience that causes transportation and use.Recently, for the storage problem that solves hydrogen has adopted hydrogen-storage alloy, promptly utilize hydrogen-storage alloy to absorb hydrogen and stored.From the weight ratio angle, the capacity of hydrogen-storage alloy storage of hydrogen is still lower, but from volume ratio than compression hydrogen and liquefaction hydrogen height, so by contrast, hydrogen-storage alloy can store more hydrogen.
Hydrogen-storage alloy is a kind of metallic compound that is formed by very strong element of hydrogen affinity and the element a little less than the hydrogen affinity, and as Mg-Ni alloy, Mg-Cu alloy, Ti-Ni alloy and R-Co alloy etc., wherein R represents rare earth metal.Like this, when hydrogen-storage alloy absorbs hydrogen, exothermic reaction will take place; And during release hydrogen, the endothermic reaction will take place from hydrogen-storage alloy.Therefore, utilize hydrogen-storage alloy reactor can constitute heat exchanger.
Fig. 1 and Fig. 2 are the structural representations of existing hydrogen-storage alloy heat exchanger and hydrogen-storage alloy reactor, and in general, the hydrogen-storage alloy heat exchanger all is that two or more assemblings are used, and has only represented one of them hydrogen-storage alloy heat exchanger among Fig. 1.As shown in Figure 1, hydrogen-storage alloy heat exchanger 1 is made of distributing pipe 10, reactor 20 and external heat-exchanging pin 30 three parts.Distributing pipe 10 is provided with a plurality of and hydrogen pipeline and reaction along the 20 hydrogen pipes that are communicated with; The outside of reactor 20 is provided with a plurality of heat exchange pins 30, so that carry out heat exchange easilier between the outside heat conduction medium such as reactor and air.When hydrogen is sent into reactor 20 by distributing pipe 10, be filled in hydrogen-storage alloy and hydrogen generation exothermic reaction in the reactor 20; And when hydrogen when reactor 20 is extracted out, the hydrogen-storage alloy and the hydrogen generation endothermic reaction.
As shown in Figure 2, reactor 20 is made of container 21, conducting strip 24 and screen pack 25.Conducting strip 24 is installed in container 21 inside, and at regular intervals each other; Between each conducting strip 24, screen pack 25 is used to filter the hydrogen-storage alloy powder in container 21 in hydrogen-storage alloy 23 fillings.When making reactor 20, at first in container 21, load the hydrogen-storage alloy powder of certain altitude, and then conducting strip 24 is installed, carry out so repeatedly just producing reactor 20.This is, the reactor of Zhi Zuoing like this, and the differing heights that the density of Zhuan Tian hydrogen-storage alloy powder will be in container and different wherein, therefore, the heat that hydrogen-storage alloy is produced during with hydrogen reaction also will be with the different deviations that produce of density.In order to make the hydrogen-storage alloy powder density in the container even, should rock container behind a certain amount of hydrogen-storage alloy powder of packing into, and should be whenever to adorn a hydrogen-storage alloy powder and just rock once or periodically and rock.
In a word, the assembly production of existing hydrogen-storage alloy reactor is cumbersome, and efficient is lower; And the deviation of the caloric value of bringing owing to the difference of hydrogen-storage alloy powder density will make the thermal efficiency of whole heat exchanger reduce.
Three, summary of the invention:
Purpose of the present invention promptly is the improvement suitable in addition to the structure of hydrogen-storage alloy reactor, so that its assembling is more convenient.
To achieve these goals, a kind of hydrogen-storage alloy reactor of the present invention, it is characterized in that constituting by container and a plurality of sintered moulded bodies that are installed in the container, sintered moulded body forms by hydrogen-storage alloy is powder sintered, its central authorities have intercommunicating pore, be provided with conducting strip between the sintered moulded body, the central authorities of conducting strip have and the corresponding intercommunicating pore of sintered moulded body central authorities' intercommunicating pore.
Aforesaid hydrogen-storage alloy reactor, wherein intercommunicating pore is circle or polygonal.
Aforesaid hydrogen-storage alloy reactor, wherein the conducting strip inboard is formed with outstanding position and works in coordination with sintered moulded body.
Aforesaid hydrogen-storage alloy reactor, wherein the inside and outside both sides of conducting strip all are formed with outstanding position and work in coordination with sintered moulded body.
Aforesaid hydrogen-storage alloy reactor wherein is provided with the porous filtering net in the intercommunicating pore.
The present invention has good assembly performance, the efficiency of assembling height; Hydrogen-storage alloy powder density in the reactor is even, caloric value is even, thermal efficiency height.After between each sintered moulded body conducting strip being installed, can further improving the assembly performance of reactor and improve its heat conductivility.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment hydrogen-storage alloy reactor of the present invention.
