Description

Technical Field

[0001] The invention relates to the technical field of microchannel radiators, in particular to a microchannel radiator based on active phased array antenna heat dissipation. Background Art

[0002] A heat sink based on an active phased array antenna is a thermal management solution that uses microfluidic technology to improve heat dissipation performance. This type of heat sink is often used in high-power electronic devices or high-performance computer systems to effectively remove the heat generated to ensure that the device maintains normal operating temperature during operation. An active phased array antenna is an antenna system with multiple transmitting and receiving elements that can adjust the direction and amplitude of the transmitted and received signals as needed. This type of antenna is often used in applications such as radar, communications, and drones, which require rapid positioning and tracking of targets. However, active phased array antennas generate a lot of heat. A microfluidic heat sink is a compact heat dissipation device that usually consists of multiple tiny channels for heat-conducting fluids to effectively cool the heat source. The main advantage of a microfluidic heat sink is its high surface area to volume ratio, which enables it to remove heat more effectively. The working principle of a microfluidic heat sink based on an active phased array antenna is as follows: Active phased array antennas generate a lot of heat, which can cause the temperature to rise, thereby reducing system performance or damaging the device. The microfluidic heat sink is integrated into the active phased array antenna system. The heat source is directly connected to the microchannel, and the heat is transferred to the heat transfer fluid in the heat sink by heat conduction. The heat transfer fluid flows in the microchannel, thereby effectively absorbing and carrying away the heat. Usually, the heat transfer fluid is carefully designed to have high thermal conductivity to ensure efficient heat dissipation. The cooled heat transfer fluid returns to the active phased array antenna system, and the heat dissipation process is circulated. This closed-loop system can continuously and effectively cool the heat source and prevent overheating.

[0003] However, due to the small gaps in the microchannels, impurities are easily accumulated inside the microchannels, which may lead to blockage and corrosion. The heat dissipation effect of the microchannel radiator will be affected by the uneven distribution of the fluid in the channel. Summary of the invention
