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.

First claim

The invention claimed is:

1. A textile machine, comprising:
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 that supply electrical energy to any combination of: individual sections or one or more of the workstations within the individual sections, to individual workstations within the same or different sections, and to multiple sections or one or more of the workstations within the multiple sections;
a cooling arrangement comprising 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.

2. The textile machine as in claim 1 , wherein the cooling arrangement further comprises a heat exchanger situated in the common discharge area.

3. The textile machine as in claim 1 , wherein the common discharge area is situated within the textile machine.

4. The textile machine as in claim 1 , further comprising an external cooling system associated with the common discharge area, wherein the waste heat is transferred to the external cooling system at the common discharge area.

5. The textile machine as in claim 1 , wherein the electrical supply units comprise one or both of power supply units or frequency inverters.

6. The textile machine as in claim 1 , wherein one of the electrical supply units is assigned to each of the sections and supplies energy to a plurality of the workstations in the section.

7. The textile machine as in claim 1 , wherein the coolant circuit comprises a single or a plurality of supply lines to the electrical supply units and a common return line from the electrical supply units to the common discharge area.

8. The textile machine as in claim 1 , wherein common discharge area is disposed at a first foot end of the textile machine.

9. The textile machine as in claim 8 , further comprising a second common discharge area disposed at a second foot end of the textile machine opposite from the first end of the textile machine.

10. The textile machine as in claim 8 , wherein the cooling arrangement comprises an operating unit.

11. The textile machine as in claim 1 , wherein the workstations or the sections comprise one or more additional sources of waste heat connected to the coolant circuit.

12. The textile machine as in claim 1 , wherein the cooling arrangement comprises multiple coolant circuits, the electrical supply units connected to the multiple coolant circuits in a configuration such that absorption of waste heat is the same in each of the multiple coolant circuits.

13. The textile machine as in claim 12 , wherein the multiple coolant circuits have the number N, wherein the waste heat of the 1st, the N+1nth, the 2N+1 nth, the 3N+1nth electrical supply units is absorbed by the first coolant circuit, the waste heat of the 2nd, the N+2nth, the 2N÷2nth, the 3N+2nth electrical supply units is absorbed by the second coolant circuit, and the waste heat of the 3rd, the N+3nth, the 2N+3nth, the 3N+3nth is absorbed by the third coolant circuit.

14. The textile machine as in claim 13 , wherein the multiple coolant circuits comprise multiple supply lines and one common return line.

15. The textile machine as in claim 14 , wherein the supply lines and the common return line extend along a longitudinal direction of the textile machine.

16. The textile machine as in claim 1 , wherein the electrical supply units comprise a cooling unit integrated into a housing of the electrical supply unit, the coolant circuit supplying coolant through the cooling unit.
