  • Patent number: 11006545
    Abstract: A textile machine includes a plurality of workstations adjacently situated in a longitudinal direction of the textile machine, the workstations combined to form multiple sections wherein each section includes one or more of the workstations. A plurality of electrical supply units supply electrical energy to the workstations, wherein one of the electrical supply units is assigned to each section or to each workstation. A cooling arrangement includes at least one coolant circuit configured with the electrical supply units such that waste heat generated by one or more of the electrical supply units is absorbed by a coolant within the coolant circuit and transported to a common discharge area of the textile machine.

  • Publication number: 20190364690
    Abstract: A textile machine (1), in particular a rotor spinning machine, comprising a plurality of adjacently situated workstations, in particular spinning and/or winding stations, which are combined to form multiple sections (2a-2f). The textile machine (1) further comprises multiple electrical supply units (3a-3f), with the aid of which the workstations and/or the sections (2a-2f) can be supplied with electrical energy, and a cooling arrangement (4) including at least one coolant circuit (16a-16c), with the aid of which waste heat of the electrical supply units (3a-3f) can be absorbed and transported to a discharge area (5) of the textile machine (1). The cooling arrangement (4) is designed in such a way that the waste heat of several of the electrical supply units (3a-3f) can be transported to a common discharge area (5) of the textile machine (1) with the aid of the at least one coolant circuit (16a-16c).
