Applied Research of Forced Convection Electric Heater for Qinghai-Tibet Railway Cars

Based on the limitations of natural convection electric heater used in Qinghai-Tibet railway cars, the utility of forced convection electric heater (group) is introduced in this paper. Through testing of the temperature of encasing surfaces, it shows that the surface temperature of the encasing under forced convection heater is in accord with the "heater electric passenger railway" (TB / T 2704-2005) standard.
