A boundary element method is developed, and used to simulate the frozen charactersof liquid section in a tube of CPL condenser.

In this equipment,CPL heat pipes were chosen as thermal conduction cell,the cooling load of condensed water was conducted to the high temperature exhaust pipe of compressor through these pipes,therefore the discharge temperature of compressor was reduced.

Numerical study of the pressure and temperature changing ofthe porous wick in capillary pumped loop evaporator;

The numerical model for the small-scale fiat capillary pumped loop(CPL)evaporator is presented,which includes liquid and vapor flow,heat transfer and phase change in the porous wick structure and heat transfer in the fluid region and metallic wall,and the entire evaporator is solved with SIMPLE algorithm as a conjugate problem.

The influence of temperature difference between upper surface and bottom surface of wick structure on startup process of the small-scale flat capillary pumped loop evaporator is analyzed,and the unsteady heat transfer model of evaporator in the fully-flooded startup stage is presented.

After analysis of the welding property of titanium and welding simulation of titanium are carried out,the welding process of titanium tube in application on tubesheet of condenser tube was introduced in Daihai Power Station,InnerMongulia has provided guide for the condenser tube unit with titanium tube.

Some reagents for degreasing,pickling and passivating the surface of condenser tube are introduced.

This paper briefly introduces three production processes applied in pipe production and discusses the feasibility of making brass condenser tube with the process of "extrusion - rolling - continuous induction annealing and horizontal continuous casting - three-roll planetary rolling - bull block drawing".
