一种电子机箱的结构设计研究

摘要

With the development of military electronic technology , electronic equipment chassis is widely used in the field of aviation and aerospace .The job of the military electronic equipment development must pay at-tention to ensure function ,also ensure the reliability of the electronic chassis products in order to ensure that the case can adapt to various flight conditions .The paper combines with the actual demand to design a kind of military electronic equipment chassis structure .Compared with the traditional plug type chassis , the chassis has some features such as large internal connections reliability an high stiffness , light weight , good manufac-turability , convenient bugging , heat conduction , etc.Through the whole machine by overall fixation by bolt , the chassis with structure stiffness big , can adapt to harsh environment of space flight , improving the working reliability of the electronic equipment and adaptability .Through the phase change heat sink thermal control device as a case , the chassis arrives good heat dissipation effect .%随着军用电子技术的发展，电子设备机箱在航空、航天等领域应用非常的广泛。为了保证机箱能够适应各种飞行条件，研制一种既要保证功能，又要保证可靠性的电子机箱产品是军用电子设备研制必须重视的工作。文中针对实际需求，研究了一种军用电子设备机箱的结构设计。与传统的插板式机箱相比，这种机箱具有刚度大、内部连接可靠性高、重量轻、工艺性好、调试方便、导热能力强等优点。整机通过贯穿的螺栓实现整体固定，其结构刚度大，能够适应严酷航天飞行环境，提高电子设备工作的可靠性和适应性，另外，通过相变热控装置作为整个机箱热沉，达到良好的散热效果。
