Summary: At drawing type application of heat exchanger of board wing type gas turbine receives gas refrigeration in the system, drop inlet temperature of gas turbine compressor, raise what condition of gas turbine high temperature falls to exert oneself, still do not have precedent in home. Be aimed at heat exchanger of board wing type, compose of brief introduction finish, assign form and function. Pass the moving data of actual measurement, undertook contrast to heat exchanger of board wing type and the function of heat exchanger tubal form. The result makes clear: Heat exchanger of board wing type is in conduct heat the respect such as the coefficient, bulk, obstruction that take energy of life, function excel is in charge of type heat exchanger, it is a kind of heat exchange equipment that is worth development. A few questions that raised heat exchanger of type of this board wing to exist in applying actually finally reach corresponding processing technique.

Keyword: Heat exchanger of board wing type; Be in charge of type heat exchanger; Air condenser

Heat exchanger of board wing type is one kind passes thermal efficiency tall, structure is compact, deft and firm, adaptability the heat exchange equipment with strong, good economy, compare with traditional envelope type heat exchanger, have two marked characteristics, weight is light, volume is minor. Apply extensively already at the domain such as petro-chemical, aerospace, electron, nuclear energy and machinery now. In applying heat exchanger of board wing type at gas turbine to take gas refrigeration system, regard air as condenser, still belong to in home first. The article takes gas refrigeration system in the light of the gas turbine of power plant of some gas turbine, analyse the performance of heat exchanger of board wing type. The gas turbine of this power plant sees a picture into gas refrigeration system 1.


Before heat exchanger of board wing type decorates Yu Yuan gas turbine to import mesh. When the design, the resistance of side of air of heat exchanger of board wing type the design is become lesser, in order to reduce the effect that obstruction exerts oneself to gas turbine. Get via computation bulk of heat exchanger of board wing type is 7. 02 M. Because the dimension of heat exchanger is more than dimension of gas turbine air inlet, for board wing

Type heat exchanger and the union with light machine air inlet better formerly, add between heat exchanger and air inlet hold one enlarge mouth, see a picture 2.
