摘要: 本文介紹了一種攝象管陰柵系統(tǒng)的傳熱計(jì)算模型,對(duì)5種不同結(jié)構(gòu)、不同功率的陰柵系統(tǒng)進(jìn)行了電子計(jì)算機(jī)計(jì)算。通過(guò)計(jì)算得出了各處的溫度、各相關(guān)部件間的熱交換情況和系統(tǒng)的總耗散功率以及各參量對(duì)它們的影響。這些對(duì)設(shè)計(jì)陰柵系統(tǒng)有一定的指導(dǎo)意義。文中還給出了一種低功率(0.6W)鋇鎳陰極陰柵系統(tǒng)的設(shè)計(jì)。它具有牢固可靠、易于裝配、速熱(數(shù)秒可達(dá)工作溫度)等優(yōu)點(diǎn)。

Abstract: In this paper a model for calculation of heat transfer of the cathode assembly in vidicon has been given. Five cathode assemblies with different constructions have been calculated by computer. The calculated results prove the model is reasonable. In this paper, there are the following calculations: the temperatures at each part of the assembly; the heat radiation and conduction between different parts; the total power dissipation of the assembly and the influences of changing physical or geometrical parameters of the parts of the assembly on the totl power dissipation. Thi paper is helpfull to design a new cathode assembly.The design and experiment of the new cathode (Ba-Ni) assembly with small power dissipation is successful. The advantages of the new assembly is firm construction, easy assembling and quick heating (arriving at the operation temperature in a few seconds). -
