基于JVPX 连接器的模块化插件结构与热设计分析

为了能够达到简化设计、缩短周期、提高互换性等目的,模块化的设计已广泛应用于插箱插件的设计当中.随着雷达对数据管道的要求越来越高,采用JVPX连接器成为解决这一需求的有效技术.另外,插件与插箱导轨接触界面的接触热阻一直是影响插件散热的关键因素.文中基于机载环境下的液冷机箱,设计了一种插拔方便、固定可靠、采用传导式散热的模块化插件,并通过在插件与机箱导轨接触面间填充液态金属来降低接触面间接触热阻.

Thermal Design and Optimization of Modular Plug-in Based on JVPX Connector

In order to simplify the design, shorten the research and development cycle and improve the compatibility, the modular design has been widely used in the plug-in design. With the increasing requirements of the radar for the data pipeline, adopting the JVPX connector is an effective technology to meet the requirements. Furthermore, the contact thermal resistance between the plug-in and cabinets has always been the key factor affecting the cooling of the plug-in. Based on liquid cooling chassis in the airborne environment, a convenient and reliable modular plug-in is designed in this paper, which adopts conduction cooling. And the contact thermal resistance is effectively reduced by filling the liquid metal between the contact surfaces.
