As for the mesh screen type, its volume multiplied by 100% its porosity was the desirable filling amount. Having considered the forgoing findings, the researchers add up the amounts of the above two types as the filling amount of the composite micro structure, with the filling fluid being acetone. In fabricating the heat spreader, a copper pipe is added to serve the filling purpose. What is more, because the manufacturing process is not carried out in a totally clean environment, there is some noncondensible gas left, which will have a negative effect on the performance of the heat spreader. Consequently, the copper pipe has to be reserved so that the exhaust gases can be evacuated after the filling is done.

In the meantime, Ingersoll and plass Kelvin line source in accordance with the concept of the underground pipe line heat source heat exchanger theory, but at that time because of low energy prices, high system costs, has not been widely applied. 70 era, the oil crisis put people's attention to the energy-saving, cost-effective use of energy, so that the development of ground-source heat pump into the climax stage, when the underground pipe from an early plastic pipes replaced by the amount of possession.

The table cores (micro pills, small pills or plain tablets) to be film coated make continuous complicated orbital motion within a closed rotating drum under the action of a streamline guide plate. Controlled by computer and according to the optimum technological parameters, they are automatically sprayed with film coating medium while hot air under a negative pressure is led in from one side of an air distributing pipe at the center of the drum, clean hot air penetrates through the tablet core layers and is discharged after being collected to the other side of the air distributing pipe by a pore duckbill-shapedair paddle embedded in the tablet core layers, so that the film coating medium sprayed on the surface of tablet cores will dry rapidly and evenly, thereby forming a layer of solid, compact, neat and smooth surface film.
