Description
Technical field
The present invention relates to fuel cell field, particularly a kind of heat transfer structure for reformation hydrogen production fuel cell unit.
Background technology
In current reformation hydrogen production fuel cell unit, raw material is mainly hydrocarbon and alcohols, and these raw materials all need through heating vaporization, then pass through heated reformate, complete hydrogen production process, and whole process is endothermic process, and reforming reaction is had relatively high expectations to temperature. Current heating means are mainly to produce high-temperature gas by combustion fuel in combustion chamber, and recycling high-temperature gas heats reformer chamber, and reformer chamber exists and is heated inhomogeneously in actual applications, and the shortcoming that temperature should not be controlled, makes reformation hydrogen production efficiency step-down.
Summary of the invention
The deficiency existing for prior art, main purpose of the present invention is to provide a kind of even and stable heat transfer structure for reformation hydrogen production fuel cell unit that conducts heat.
For achieving the above object, the invention provides following technical scheme: a kind of heat transfer structure for reformation hydrogen production fuel cell unit, comprise and be arranged on the first endothermic section between combustion chamber and reformer chamber and be arranged on the second endothermic section in reformer chamber, described the first endothermic section comprises the first fins set being made up of some the first fins and is arranged on the baffle plate of the first fins set below, described the second endothermic section comprises some the second fins set that are set up in parallel, described each second fins set is by some the second fin compositions, and described baffle plate below is provided with fin.
Preferably, described the first fin and the second fin be shaped as square.
The present invention has the following advantages with respect to prior art tool, heat in combustion chamber blows to the first endothermic section under the guiding of air blast, then blow to the second endothermic section, the first fins set in the first endothermic section absorbs the heat in high-temperature gas, the fin that is arranged on baffle plate below can heat the vaporization runner of fuel, enters combustion chambers burn after carburretion. In the second endothermic section, the quantity of fin and density are all greater than the first endothermic section, and in high-temperature gas, more heat just can be absorbed by the second endothermic section like this, and the temperature of reformer chamber just can rise. Wherein in the quantity of the second fins set and each second fins set, the spacing of quantity, thickness and adjacent two second fins of the second fin can arrange according to the difference of raw material, the heat that such the second endothermic section can absorb in the time of work will produce difference, so the temperature of reformer chamber just can produce difference, the different requirements of temperature just can meet different material to reforming reaction with this time. Heat transfer structure of the present invention goes for the reformation hydrogen production fuel cell unit of multiple kinds.
