BIM (Building Information Modeling)-based curtain wall parametrization design method

The invention relates to a BIM (Building Information Modeling)-based curtain wall parametrization design method, which comprises the following steps: building a BIM mass model of a curtain wall; building multiple parametrization basic unit plate models; assembling each basic unit plate model to the BIM mass model in a simulating manner, checking collision, and judging the feasibility of the designing scheme according to the assembly situation; integrating the well-assembled BIM model with other crossed professional BIM model, and checking whether the integrated model conflicts or not. Through BIM, the parametrization design of a curtain wall project is realized, the problem of building a curved-surface curtain wall by using standard rectangular unit plates is handled, the parametrization dimension driven design and adjustment functions are integrated, so that the control dimension of the curtain wall units is amended at any time, thus the design efficiency is improved, the error rate is reduced, and a project delay risk is lowered; the collision checking function of the BIM technology is adopted, so the change, monitoring and dynamic management on the curtain wall design are realized. The BIM-based curtain wall parametrization design method can be used in the design of curtain walls.

Bipolar plate for proton exchange membrane fuel cell

The invention provides an improvement of a proton exchange membrane fuel cell bipolar plate and is characterized in that a middle coolant flow field is made from a flexible graphite plate and the flexible graphite plate is peripherally equipped with a rigid thickness limit frame. The flexibility of the flexible graphite and certain elastic deformation thereof, not only can compensate for the inevitable unevenness deviation caused by the processing of anode flow field plate and cathode flow field plate, and ensure that the flow field plate surfaces are contacted closely and pressed together, so as to effectively reduce the contact resistance between the flow field plates, to achieve the minimized combination of contact resistances and to basically achieve no loss of interface voltage; but also achieve excellent plane thermal conductivity, so as to improve the cooling effect, limit the temperature rising of the cell stack and to achieve good-performance assembled batteries; in addition, since the flexible graphite texture is relatively soft in texture, the depth of a water flow channel can be relatively lower, so that the processing is easier. The combination performance is obviously superior to that of the rigid graphite cooling flow field and that of the flexible graphite reaction gas flow field. The three flow field plates are manufactured separately, so that the flow field can be changed easily and the independent optimization of the flow field can be realized.
