Abstract
The utility model discloses a spread connector. The spread connector is provided with a flow passage space capable of covering a fuel inlet of a fuel cell. An inlet flow passage is formed on the side of the spread connector away from the fuel inlet, and is communicated with the flow passage space; a plurality of locking holes penetrating the spread connector are arranged on the edge of the spread connector and not in contact with the flow passage space; the spread connector can penetrate the locking holes through a screw, to transversely cover and be fixed on the end surface of the fuel cell with the fuel inlet; after the spread connector covers and is fixed on the fuel cell, the fuel inlet of the fuel cell is completely covered by the flow passage space. When the spread connector is assembled on the fuel cell, due to the arrangement of the inlet flow passage away from the fuel inlet of the fuel cell, the flow direction of the fuel changes when fuel flows into the flow passage space through the inlet flow passage, the flow velocity is reduced, and then the spreading of fuel flowing in the flow passage space is relatively uniform.
Description
Technical field
The utility model relates to a kind of diffusion joint, especially refers to a kind of being arranged on the fuel cell, with so that fuel through after this flowing into the diffusion joint of fuel cell.
Background technology
When fuel is delivered to fuel cell, fuel conduit must connect a diffusion joint, make fuel can diffuse to the fuel inlet place of the big fuel cell of area,, and then allow fuel cell generation effect so that fuel enters fuel battery inside in mode uniformly by the little pipeline of area.
As shown in Figure 1, this diffusion joint uprightly is arranged at through its locking hole in the fuel inlet place of fuel cell with screw, and the flow channel space in this diffusion joint directly communicates with fuel inlet, and flows to not through changing.Yet above-mentioned existing diffusion joint has following shortcoming:
One. because the flow direction of runner did not change, so fuel can concentrate on central authorities in diffusion joint, and more uneven mode enters the fuel inlet of fuel cell.
Two. diffusion joint is uprightly to be arranged on the fuel inlet of fuel cell, because of the cause of diffusion joint can take bigger volume than all the other positions, and then causes and uses and the inconvenience of placing.
Summary of the invention
The utility model purpose is: a kind of diffusion joint is provided, when it is installed on the fuel cell, because being the fuel inlet that departs from fuel cell, entrance channel is provided with, when therefore fuel flows to flow channel space by entrance channel, its flow direction needs to change, and the transformation that flows to can make flow velocity descend, and then makes fuel diffusion comparatively even when flow channel space flows.
The technical solution of the utility model is: a kind of diffusion joint, it is arranged on the fuel cell, described diffusion joint has the flow channel space of the fuel inlet that is enough to cover fuel cell, diffusion joint is provided with entrance channel departing from a fuel inlet side far away, this entrance channel is communicated with flow channel space, described diffusion joint does not contact on the edge of flow channel space has several locking holes that run through this diffusion joint, diffusion joint can be passed above-mentioned locking hole by screw and laterally be covered and be fixed on the end face that fuel cell has fuel inlet, when the diffusion joint covering was fixed on the fuel cell, the fuel inlet of fuel cell was covered fully by flow channel space.
Described diffusion joint is similar leg-of-mutton platy structure, and described locking hole is positioned on three angles at diffusion joint edge.
Described flow channel space is divided into both sides, and wherein a side is the rectangular-shaped outlet flow that is used to cover the fuel inlet of fuel cell, and opposite side is the diffusion runner of class homoedeltidium shape, and described entrance channel is arranged on the bight of diffusion runner away from outlet flow.Described diffusion runner is the tabular space of both sides linear or camber line shape.
Described flow channel space is arranged with the bottom surface in diffusion joint, and the flow channel space inner height is all identical.Described entrance channel is cylindric through hole.
The utility model advantage is:
1. diffusion joint of the present utility model has on the end face of fuel inlet for laterally being covered in fuel cell, but not on the common fuel inlet place that uprightly is arranged at fuel cell, the fuel cell that therefore this diffusion joint is installed can be more convenient on placing.
2. when this diffusion joint is installed on the fuel cell, because being the fuel inlet that departs from fuel cell, entrance channel is provided with, when therefore fuel flows to flow channel space by entrance channel, its flow direction needs to change, and the transformation that flows to can make flow velocity descend, and then makes fuel diffusion comparatively even when flow channel space flows.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is that existing diffusion joint is arranged at the stereogram on the fuel cell;
Fig. 2 is arranged at stereogram on the fuel cell for the utility model;
Fig. 3 is the vertical view of the utility model diffusion joint;
Fig. 4 is the upward view of the utility model diffusion joint;
Fig. 5 is the stereogram of the utility model diffusion joint.
Wherein: 1 diffusion joint; 2 locking holes; 3 flow channel spaces; 31 outlet flow; 32 diffusion runners; 4 entrance channels; 5 flow channel spaces; 6 locking holes.
Embodiment
Embodiment: as shown in Figure 2, a kind of diffusion joint, this diffusion joint 1 laterally covers and is fixed on the end face that fuel cell has fuel inlet, make the fuel can be after diffusion joint 1 by the little pipeline of area, evenly flow to the fuel inlet place of the big fuel cell of area, and because of diffusion joint 1 is horizontal covering, therefore the inconvenience that is brought by diffusion joint can drop to minimum.
Extremely shown in Figure 5 as Fig. 2, this diffusion joint 1 is similar leg-of-mutton platy structure, and have three locking holes 2 that run through this diffusion joint on three angles, its edge, screw is covered this diffusion joint 1 via these three locking holes 2 is fixed on the end face that fuel cell has fuel inlet, the end face of these screws be lower than or etc. be higher than this diffusion joint 1.
This diffusion joint 1 also has the flow channel space 3 of the fuel inlet that is enough to cover fuel cell, and diffusion joint 1 is provided with entrance channel 4 departing from a fuel inlet side far away, and this entrance channel 4 is communicated with flow channel space 3.When diffusion joint 1 covering was fixed on the fuel cell, the fuel inlet of fuel cell was covered fully by flow channel space 3, and wherein flow channel space 3 is arranged with in the bottom surface of diffusion joint 1, and the height of flow channel space 3 is all identical.Described flow channel space 3 is divided into both sides, and wherein a side is the rectangular-shaped outlet flow 31 that is used to cover the fuel inlet of fuel cell, and opposite side is the diffusion runner 32 of class homoedeltidium shape.Described entrance channel 4 is arranged on the bight of diffusion runner 32 away from outlet flow 31.
When diffusion joint 1 is installed on the fuel cell, because being the fuel inlets that depart from fuel cell, entrance channel 4 is provided with, when therefore fuel flows to flow channel space 3 by entrance channel, the fuel contact is on the end face of fuel cell, making it flow to transformation causes flow velocity to descend, and then make fuel diffusion comparatively even when flow channel space 3 flows, and flow into fuel battery insides through outlet flow 31 afterwards, cause fuel cell to act on.
In addition, in the present embodiment, described diffusion runner 32 is rectilinear tabular spaces, both sides, also can be the tabular space of both sides arc; And but the shape of the fuel inlet of the shape fuel cell of described outlet flow 31 is made corresponding change.
