Abstract

The field replaceable module comprises a heat dissipation bottom cover and a heat dissipation top cover, the heat dissipation bottom cover is of a semi-closed cubic structure with the top open, the top of the heat dissipation bottom cover is fixedly connected with the heat dissipation top cover to form a closed cubic structure, and heat dissipation fins are arranged on the heat dissipation bottom cover and the heat dissipation top cover; the module further comprises a mainboard, a CPU, a power supply chip and a bridge sheet group which are arranged in the closed cubic structure. The CPU is arranged on the front surface of the mainboard, and the bridge sheet group is arranged on the back surface of the mainboard; the module further comprises a first heat dissipation unit and a second heat dissipation unit. The first heat dissipation unit is of a detachable structure connected with the heat dissipation top cover in an attached mode and is used for transmitting heat generated by the CPU to the heat dissipation top cover. The second heat dissipation unit is of a detachable structure connected with the heat dissipation bottom cover in an attached mode and is used for transmitting heat generated by the bridge piece set to the heat dissipation bottom cover.

Description

technical field [0001] The invention relates to the technical field of avionics systems, in particular to a field replaceable module. Background technique [0002] The field replaceable module (ie LRM module) is the hardware foundation of the fourth-generation integrated avionics system. It is gradually recognized by the military market due to its high degree of standardization, small size, and easy maintenance, and is increasingly used in In harsh environments, such as the wild, humid, salt spray, high temperature, hot and humid environment. [0003] The LRM module cannot place a fan due to its small space and airtight design. In order to protect the stability of the equipment and the performance against harsh environments, it is necessary to quickly take away the heat generated by the CPU, bridge chips, power modules, and power chips of the high-power consumption devices. This is a key problem that needs to be solved, and it is also a difficult problem. Moreover, LRM mod...
