Reducing energy consumption and improving device efficiency are important ways to realize efficient heat dissipation of microdevices, this paper developed a new bionic fractal microchannel heat sink based on fractal theory and topological optimization ideas, which introduced a binary flow stagnation zone optimization based on topological optimization ideas on the basic fractal microchannel. The thermal and hydraulic properties of a nanofluid in a fractal microchannel heat sink (FMCHS) have been numerically simulated with the fractal dimensions (fd = 1, 1.5, and 2) and Reynolds number (Re = 200–1600) as variables, and the comprehensive performance has been analyzed. The results showed that the introduction of the optimization increases the central velocity of the microchannel by 7.14–18.2%. With fractal dimensions of 1.5 and 2, the flow improvement and velocity increase are significant, and a significant Nusselt number improvement is obtained. The best comprehensive performance is obtained for FMCHS with a fractal dimension of 1.5, with an optimization effect of 8.3%.

Due to its excellent performance and high design freedom, the lattice structure has shown excellent capabilities and considerable potential in aerospace and other fields. This paper proposes a method to map the biometric model to the lattice structure. Taking leaf veins as bionic objects, they are used to generate a bionic design with a gradient lattice structure to improve the performance of a heat exchanger. In order to achieve the above goals, this article also proposes a leaf vein model and a mapping method that combine the leaf vein model with the lattice structure. A series of transient thermal finite element simulations was conducted to evaluate and compare the heat dissipation performance of different designs. The analysis results show that the combination of the bionic design and the lattice structure effectively improves the heat dissipation performance of the lattice structure heat exchanger. The results indicate that the application of bionic design in lattice structure design has feasibility and predictable potential.

“…In addition to the selection of working fluids with superior performance, it is of great significance to improve the energy efficiency of the heat exchange system by adopting appropriate enhanced structure 35,36 . The enhanced structure can weaken the thermal resistance of boundary layer and increase the turbulence of working fluid flow, which is beneficial to the application of nanofluids in heat exchange system 37,38 .…”

In this paper, in order to improve the efficiency of waste heat utilization, based on the movement type and shape of the snake, snake bionic surfaces with different structures were designed, and CuO–H2O nanofluids were used instead of traditional working fluids, and they were coupled together and applied to waste heat utilization equipment. The main work is to experimentally study the effects of nanofluids mass fraction (w = 0.1 wt%, 0.3 wt%, 0.5 wt%), amplitude of bionic channel structure (A = 1 mm, A = 2 mm, A = 3 mm), angular frequency of bionic channel structure (ω = 20 rad/s, ω = 25 rad/s, ω = 30 rad/s), phase shift of bionic channel structure (α = 0°, 90°, 180°), and Reynolds number (Re = 1,300–1800) on the flow and heat transfer characteristics of working fluid. It was found that the heat transfer capacity of nanofluids increases with nanofluids mass fraction, angular frequency, amplitude and phase shift. Finally, the comprehensive performance of the whole experimental system was studied, and it was found that the greater the angular frequency, amplitude and phase shift, the better the comprehensive performance of the heat exchanger.
