Description
Technical field
This utility model relates to fuel cell field, particularly to 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 are required for through heating vaporization, then through heated reformate, complete hydrogen production process, and whole process is endothermic process, and reforming reaction is higher to the requirement of temperature.Current heating means mainly produce high-temperature gas by the fuel that burns in a combustion chamber, and reformer chamber is heated by recycling high-temperature gas, and reformer chamber existence is heated uneven in actual applications, and the shortcoming that temperature should not control makes reformation hydrogen production efficiency step-down.
Utility model content
The deficiency existed for prior art, main purpose of the present utility model is to provide a kind of uniform and stable heat transfer structure for reformation hydrogen production fuel cell unit that conducts heat.
For achieving the above object, this utility model provides following technical scheme: a kind of heat transfer structure for reformation hydrogen production fuel cell unit, including the first endothermic section being arranged between combustor and reformer chamber and the second endothermic section being arranged in reformer chamber, described first endothermic section includes the first fins set being made up of some first fins and is arranged on the baffle plate below the first fins set, described second endothermic section includes some the second fins set being set up in parallel, described each second fins set, by some second fin compositions, is provided with fin below described baffle plate.
Preferably, described first fin and the second fin be shaped as square.
This utility model has the advantage that relative to prior art, heat in combustor blows to the first endothermic section under the guiding of aerator, then the second endothermic section is blowed to, the first fins set in first endothermic section absorbs the heat in high-temperature gas, it is arranged on the fin below baffle plate can the vaporization runner of fuel be heated, after carburretion, enters combustion chambers burn.In second endothermic section, quantity and the density of fin are both greater than the first endothermic section, and in such high-temperature gas, more heat just can be absorbed by the second endothermic section, and the temperature of reformer chamber will rise.Wherein the quantity of the second fins set can be arranged according to the difference of raw material with the spacing of the quantity of the second fin, thickness and adjacent two the second fins in each second fins set, the heat that such second endothermic section operationally can absorb will produce difference, so the temperature of reformer chamber will produce difference, it becomes possible to meet different material to the different requirements of temperature during reforming reaction with this.Heat transfer structure of the present utility model goes for the reformation hydrogen production fuel cell unit of multiple kind.

In figure: 1, reformer chamber；2, combustor；3, the first endothermic section；4, the second endothermic section；5, the first fins set；6, baffle plate；7, fin；8, the second fins set；9, the second fin；10, the first fin.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of heat transfer structure for reformation hydrogen production fuel cell unit, including the first endothermic section 3 being arranged between combustor 2 and reformer chamber 1 and the second endothermic section 4 being arranged in reformer chamber 1, described first endothermic section 3 includes the first fins set 5 being made up of some first fins 10 and is arranged on the baffle plate 6 below the first fins set 5, described second endothermic section 4 includes that some the second fins set 8 being set up in parallel, described each second fins set 8 are formed by some second fins 9.
Operation principle of the present utility model is: the heat produced in combustor 2 blows to the first endothermic section 3 under the guiding of aerator, then the second endothermic section 4 is blowed to, the first fins set 5 in first endothermic section 3 absorbs the heat in high-temperature gas, it is arranged on the fin below baffle plate 6 absorb heat from the first fins set 5 and can the vaporization runner of fuel be heated, enters combustor 2 after carburretion and burn.In second endothermic section 4, quantity and the density of fin are both greater than the first endothermic section 3, and in such high-temperature gas, more heat just can be absorbed by the second endothermic section 4, and the temperature of reformer chamber 1 will rise.Wherein the quantity of the second fins set 8 can be arranged according to the difference of raw material with the spacing of the quantity of the second fin 9, thickness and adjacent two the second fins 9 in each second fins set 8, the heat that such second endothermic section 4 operationally can absorb will produce difference, so the temperature of reformer chamber 1 will produce difference, just can meet different material with this and different requirements of temperature during reforming reaction, heat transfer structure of the present utility model are gone for the reformation hydrogen production fuel cell unit of multiple kind.Certainly, by regulating the air force of aerator, can vary in the caloric receptivity of the second endothermic section 4 such that it is able to realize regulation temperature.
Several the second fins set 8 laid out in parallel are in reformer chamber 1, and such second endothermic section 4 can absorb the heat in high-temperature gas uniformly, and in reformer chamber 1, temperature everywhere is more uniform, and compared to prior art, the efficiency of reforming reaction can be improved.
Wherein, being shaped as of the first fin 10 and the second fin 9 is square, and high-temperature gas can pass through from the gap of adjacent fins, and fin is relatively big with the contact area of high-temperature gas, and endothermic effect is good.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
