内燃机散热器设计的新数学模型

提出内燃机散热器设计的Ｈ－ＮＥ数学模型。方法该模型是建立在多重非线性回归技术的基础上，并采用二次拟合方法光顺原始数据；通过对散热器优化设计的精确分析，得到一些充要的约束条件。结果应用该模型对１３０１Ｃ散热器进行了重新优化设计，新的散热器在传热系数和制造成本方面均低于原来的散热器。结论该模型用于散热器的设计，可使散热器性能提高，散热面积减小，并可拓展到适合的领域。

New Math Model for Designing Engine Radiator

Aim To raise the H-NE math model for designing engine radiators.Methods Thismodel was founded on multi-nonlinear regression technology,and the quadratic equatingmethod was used to smooth original data.Through the sensitivity analysis about radiatoroptimization designing,some major restraints were obtained.Results Type 1301C radiator wasoptimizingly renwed by use o this model,and the new radiator is more excellent than theold one in respect of the heat transfer factor and the manufacturing cost.Conclusion Theradiation performance can be improved,the area can be reduced,and the fitting scope can bewidened if this model is used in designing radiators.
