Model of the Cooling System

The thermohydrodynamic characteristics of the flow in the heated micro-channels depend on the following factors the heat flux on the wall, which determines the intensity of the vaporization, the location of the meniscus, the difference between the inlet and outlet pressures, the capillary, and mass and friction forces which act on the liquid and vapor. 

The processes in a cooling system of electronic devices with high power density can be modeled as follows. The coolant with temperature T2.0 and pressure F2.0 enters into the micro-channel from the tank (5) (Fig. 10.2). The mass capacity of the liquid in the tank (5) is large enough, therefore the heat flux from the micro-channel

A step-by-step analysis is given for the direct computation of 2D heat flow and safe pitching of the cooling pipes. Two models of the cooling system have been selected and calculations have been carried out for an existing vessel. On the one model this analysis is compared with the 3D finite-element analysis for obtaining insulation conductance for various cooling pipes. A safety factor is established.
