Reason system is heated by the way that conductive fluid is continual and steady to the hydrogen bearing alloy in each hydrogen storage vessel.The first of gas passage enters and leaves gas
One of pipe 34 and the second discrepancy tracheae 35 are used for connection and are flushed with hydrogen access, hydrogen supply access as interface is flushed with hydrogen, it is of course also possible to
Only setting one enters and leaves tracheae.In being flushed with hydrogen operating condition, which connect with access is flushed with hydrogen；In hydrogen supply operating condition, the discrepancy gas
Pipe is connect with hydrogen supply access.In general, the first, second discrepancy tracheae of setting and the first, second valve are technique requirements, i.e. hydrogen storage is held
After device completes filling hydrogen bearing alloy, need to be activated hydrogen bearing alloy；Activating process process vacuumized, gas
Body displacement, multiple charge and discharge hydrogen etc., it is necessary to two discrepancy tracheaes and valve to facilitate operation.Qualified products after the completion of activation
In practical applications, one of discrepancy tracheae and valve are only used, another enters and leaves tracheae and valve is closed always.?
When being flushed with hydrogen operating condition, the hydrogen of external hydrogen source can branch to each hydrogen storage vessel by gas passage；In hydrogen supply operating condition, each hydrogen storage
The hydrogen of container release can be collected by gas passage.
For hydrogen-storing device, fluid path is at least partially disposed in inside water tank, with conductive fluid entrance and conductive fluid
Outlet.Conductive fluid flows through the outer wall of each hydrogen storage vessel in water tank internal flow, in the flow process, realization and hydrogen storage
The heat exchange of hydrogen bearing alloy in container.In addition, since the groove 61 on the groove and second partition in first partition is to hand over up and down
For placement, so that conductive fluid circuitous flow inside water tank, increases the effect of heat exchange.In the case where being flushed with hydrogen operating condition, by outer
Equipment conductive fluid after cooling in portion's enters water tank by conductive fluid entrance, and conductive fluid after cooling is inside water tank and hydrogen storage vessel
Heat exchange absorbs hydride and forms the heat generated, and exported and flowed out by conductive fluid；Under hydrogen supply operating condition, set by outside
Conductive fluid after standby heating (also can use the waste heat generated in fuel cell operations) by conductive fluid entrance into
Enter water tank and is heated to hydrogen bearing alloy.It is either flushed with hydrogen operating condition or hydrogen supply operating condition, can use is the same conductive fluid,
Inside water tank and the flow direction of entry and exit and flow velocity are determined by the design of external heat management device.Water tank can be rectangular
Body is also possible to other closed structure bodies for being capable of providing the conductive fluid flowing space, such as ellipsoidal structure body, track type structure
Body etc..It is conductive fluid from flowing into water tank, flow through the road that each hydrogen storage vessel outer wall passed through to outflow water tank for fluid path
Diameter.Conductive fluid entrance is connected to the heat exchange space of forefront.Conductive fluid outlet is connected to the heat exchange space of rearmost, such as logical
Cross return pipe connection.
For hydrogen-storing device, hydrogen-powered vehicle can be applied to.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made.
