The invention provides a multi-channel comprehensive
assembly with efficient double-sided liquid cooling heat dissipation capability, and belongs to a
radar assembly heat dissipation technology. The integrated
assembly adopts a
sandwich type structural
layout, and four-channel T / R assemblies on the two sides and a liquid cooling plate in the middle are integrated together. According to the liquid cooling plate, an S-shaped
water channel is arranged in a shell, and a heat conduction turbulent flow column is arranged at the position, corresponding to a power
amplifier chip, of the S-shaped
water channel. The density of the heat conduction flow-around columns is gradually increased from the water inlet to the water outlet, the number of the heat conduction flow-around columns is reasonably optimized according to calculation and
simulation analysis at the
chip positions with different liquid path lengths from the liquid inlet, the number of the near-end flow-around columns is small, and the number of the far-end flow-around columns is large. The heat conduction turbulent flow columns can improve the local flow speed of cooling liquid through the turbulent flow effect, meanwhile, the local
solid-liquid heat exchange area is increased, and the heat dissipation efficiency is improved. The heat dissipation performance of the T / R assembly can be effectively improved, the
temperature difference of the power
amplifier chips between different channels is controlled within a
small range, and the phase consistency of the assembly is improved.
