摘要:
The main sources of heat in a scroll pump are cooled efficiently by a single cooling fan so that noise and, in particular, fan-generated noise, can be kept low. The scroll pump includes a pump head assembly, a pump motor, a cooling fan that produces a cooling air flow in the pump, a cowling in which the pump head assembly, pump motor and cooling fan are housed and juxtaposed with one another in an axial direction of the pump, and a shroud disposed within the cowling and extending around the pump motor to define a tunnel with the motor and through which the air flow of the cooling fan is directed.
