Description
The technical field is as follows:
the utility model relates to a vortex type runner apron for hydrogen circulating pump.
Background art:
the fuel cell generates electric energy through electrochemical reaction between combustible substances (hydrogen) and oxygen in air, wherein after the reaction of the fuel cell, discharged gas contains a large amount of hydrogen, and if the hydrogen is directly discharged into the atmosphere, on one hand, energy is wasted, on the other hand, the environment is polluted, and on the other hand, the hydrogen is flammable and combustible, so that danger is generated, and therefore, the hydrogen needs to be recycled. At present, these hydrogen-containing mixed gases are generally recycled to the fuel cell by a hydrogen circulation pump for recycling. At present, a vortex type hydrogen circulating pump is available in the market, wherein an impeller of the vortex type hydrogen circulating pump is a disc with radial blades, grooves are formed between the blades, and gas obtains higher pressure through repeated vortex motion of the grooves, namely a flow channel and the grooves. The impeller rotating speed of the vortex type hydrogen circulating pump can reach 2-3 thousands of revolutions per minute, a large amount of heat can be generated in the working process, the boosting cavity and the impeller need to be timely dissipated, the boosting cavity mainly depends on the runner cover plate to dissipate the heat, the existing runner cover plate is unreasonable in structural design and poor in heat dissipation effect, and the shutdown condition caused by untimely heat dissipation often occurs.
Therefore, the heat dissipation problem of the flow passage cover plate of the hydrogen circulating pump becomes a technical problem to be solved urgently in the industry.
The utility model has the following contents:
the utility model discloses a remedy prior art not enough, provide a vortex type runner apron for hydrogen circulating pump, solved runner apron radiating effect in the past poor, the heat gives off the problem that untimely leads to shutting down.
The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be:
the utility model provides a vortex type runner apron for hydrogen circulating pump, includes the apron body, apron body inside surface is equipped with annular flow channel, and annular flow channel's bottom is isolated through the bridge cut-off, is equipped with air inlet and gas vent in the annular flow channel of bridge cut-off both sides respectively, and air inlet and gas vent lead to the outside of apron body, and the outside surface middle part of apron body is equipped with a vertical heat dissipation muscle, and the both sides of vertical heat dissipation muscle are equipped with a plurality of horizontal heat dissipation muscle.
And transverse heat dissipation ribs are arranged on two sides of the air inlet and the air outlet.
