本文主要是为了弥补一九七九年研制报告的不足,探讨解决扁管散热器使用热水流量低于100公斤/小时时的不稳定段的热工性能及计算方法。一、扁管散热器原研制过程的一些特点我们曾着重做过在稳定温差△T=64.5℃情况下的G-Q曲线试验和散热器在同一试验流量(G_试)下的不同温差(△T)的k值试验。在G-Q特性曲线的试验中,我们曾做过单板、双板、单板带对流片、双板带对流片四种板型及不同长度扁管散热器的试验,通过试验可以看外,各种板型扁管散热器
This article is mainly to make up for the deficiencies in the development report in 1979, to explore the solution to the thermal performance of the unstable section of the flat tube radiator when the hot water flow is less than 100 kg/hour and the calculation method. First, some characteristics of the original development process of the flat tube radiator We have done the GQ curve test under the condition of stable temperature difference △T=64.5°C and different temperature difference of the radiator under the same test flow (G_ test) (△T k value test. In the test of the GQ characteristic curve, we have done tests on single-plate, double-plate, single-plate convection, double-plate convection, and flat tube radiators of different lengths. Plate type flat tube radiator
