Obviously, the optimization management in middle-sized or small cities of China is very necessary. The basic characteristics of municipal solid waste generated in middle-sized or small cities of China are put forward in the paper. The total amount of municipal solid waste generated in middle-sized or small cities is significantly less than that in large cities. The amount of garbage is about 1 kg per capita and year. In the garbage, inorganic material is more than organic material, the combustible less than incombustible and the amount of uncompostable garbage more than the amount of garbage that can be disposed for composting. The value of heat of garbage is about 800 kal/kg.

And, theoretical and experimental studies have been carried out of the performance of the heat transfer enhancement by adding a proper amount of nanoparticles to the thermosiphon with water as the working fluid. Compared with the ordinary thermosiphon, results indicate that this heat pipes posses such advantages as good startup, lower tube wall temperature, and its heat transfer coefficient is increased by 47～96%, heat flux is increased by 7.6～15% in the range of the experiment. The performance of the heat transfer relates to the diameter and the volume fraction of nanoparticle.

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.
