Cooling Scheme and Thermodynamic Calculation for Motor Used in Small Pipe Jacking Machine of Mine

For the special structure and appication that small pipe jacking excavating equipment has small volume, large power and serious heating in coal mine, the cooling system of motor is design. The motor S type cooling pipe and grouting pipe are used to complete the heat dissipation. On this basis, relevant principle of fluid heat transfer is used to carry out heat transfer calculation.The result shows that the design scheme meets requirement of heat dissipation.
