Zusammenfassung:	The utility model relates to the technical field of pumps, in particular to a novel roots vacuum pump. The novel roots vacuum pump is characterized in that the novel roots vacuum pump comprises a rotor, a pump body, a gas inlet, an aftercooler and a gas exhaust port. In the novel roots vacuum pump, the aftercooler is arranged at the gas exhaust port and is used for cooling pumped gas. The aftercooler is arranged at the gas exhaust port and exchanges heat with the pumped gas.
