Simulated liquid absorbing core for heat uniformizing plate

Abstract

The invention discloses a simulated liquid absorbing core for a heat uniformizing plate. The simulated liquid absorbing core is structurally characterized in that based on efficient transport structure of a plant leaf, a novel heat uniformizing plate in the simulated transport structure of the plant leaf is designed according to the point-to-surface transport principle of the plant leaf and the shortest path principle of transport. The heat uniformizing plate can be integrally designed with the liquid absorbing core, so that working medium can quickly enter a fractal passage under the action of capillary pressure, can quickly enter a polygonal microstructure tissue enclosed by the fractal passage and can reach the integral condensing surface of the heat uniformizing plate rapidly, and the working medium is quickly condensed into liquid state and can return to an evaporating end under the action of the capillary pressure, and one cycle is completed for preparation of the next evaporation. Meanwhile, due to the polygonal micropassage structure of a simulated vein structure, the liquid working medium is promoted to quickly flow to the periphery of a condensing end along the network passage of the liquid absorbing core, circulation of a working medium transport loop is accelerated, heat transfer efficiency is improved, and the simulated liquid absorbing core is small in size and applicable to precise electronic equipment.
