Cooling coefficient

Fig. 6. Two-phase pumping system used for cryogenic cooling coefficient studies.

The water coohng jacket for the PM motor is proposed in this paper. The water cooling channel will be evaluated by the comprehensive cooling coefficient which considering the cooling efficiency, heating uniformity, flow resistance, etc. Cooling system likes a pipe network for these four wheel motors distributed layout on the articulated dump truck. The co-simulation... 

The evaluation method of the cooling effect of jacket is as following simulating the temperature difference between the case and water in the chaimel with respect of heat emission capacity of driving motor while keep the coolant flow rate constant. The cooling coefficient k in Equation 1 is used as evaluating index to analyze the different channel structures. 

Used widi steam or coofing. Liquid flow velocities are low and the flow is poorly distributed. Natural convection equations are suitable and cooling coefficients have low values. Conventional jackets are best applied to small vessels or high pressure applications, where flie vessel internal pressure is twice the jacket pressure as a minimum. The conventional jacket is the most common... 

Here p and Cp are, respectively, the mass density and specific heat of the system Q is the heat of reaction E is the activation energy R the gas constant and y = a /V, a being the Newton cooling coefficient. 

Resistance to heating and cooling Coefficient of thermal expansion...
