We investigate a three-terminal heat pump through classical molecular dynamics simulations. It is reported an asymmetrical structure is necessary for the molecular heat pump. There exists an optimum pumping efficiency by controlling the asymmetry and the average temperature of the heat pump. The efficiency increases with the decreasing of the temperature difference between the hot and cold heat baths.
