Abstract

The invention discloses a high-efficiency composite thermal control device, comprising a heat transfer cold plate assembly contacted and connected with a T / R assembly, a heat storage cold plate (9) contacted and connected with the heat transfer cold plate assembly, arranged on the The liquid-cooled cold plate (10) and the liquid-cooled interface assembly (12) at the bottom of the heat storage cold plate (9), the heat transfer cold plate assembly includes a number of heat transfer cold plates, one end of the heat transfer cold plate is connected to the The T / R assembly is contacted and connected, and the other end is inserted into the heat storage cold plate (9), and the heat storage cold plate (9) is provided with a phase change material (907) for absorbing heat, and the liquid-cooled cold plate (10 ) is provided with a cooling channel (1004) for cooling that communicates with the liquid cooling interface assembly (12), and the liquid cooling interface assembly (12) is connected to an external liquid cooler to pass through the cooling channel (1004) cooling the liquid-cooled cold plate (10) and the heat storage cold plate (9). The invention can realize high-efficiency heat dissipation for the active phased array antenna.

Description

technical field [0001] The invention belongs to the technical field of thermal control of electronic equipment, and more specifically relates to a high-efficiency composite thermal control device. Background technique [0002] In recent years, with the continuous progress and development of science and technology, the integration level of electronic devices has increased exponentially, and the heat flux has risen linearly, and the heat dissipation problem of high-speed electronic devices has become increasingly prominent. The status and role of design technology in electronic equipment is also increasing. Military electronic equipment has stricter heat dissipation requirements, and active phased array antennas are a typical representative of thermal control problems. [0003] Compared with other radars, active phased array radar has good performance and advantages, and has become the mainstream of radar development today. In order to achieve the requirements of high perfor...

Problems solved by technology

Its thermal control design is often based on experience, and the design idea is greatly influenced by the predecessors. In order to meet the heat dissipation requirements, an excessive margin is often left

This kind of design can often basically meet the requirements, but the result is often either the equipment is bloated, the system is huge, or the heat dissipation requirements of the system cannot be met at all, and the design cycle is long and repeated, and it will seriously affect the overall scheme of the system. implementation
