A temperature control assembly controls the temperature of functional parts of a printing machine. The temperature control assembly comprises a plurality of assembly-side sub-circuits, the temperature of which is to be individually controlled, each sub-circuit having a temperature-control fluid outlet and a temperature-control fluid inlet, on each of which, in order to form a respective temperature control circuit, one or more functional parts can be connected as loads of a temperature-controlling external temperature control sub-circuit by the use of releasable connections, and which, on the feed side of the temperature control thereof, are or can be thermally and fluidically coupled, via respective removal points, to a common feed line, and on the return side, via each return point, to a common fluid return. The temperature control assembly is configured as a structurally independent assembly comprising the assembly-side temperature control circuits thereof and the feed and return, and a temperature control device that controls the temperature of the temperature control fluid supplied to the feed, one of on and in a single-component or in a multi-component frame of the temperature control assembly. The temperature control device is provided in a fluid stream between the last return point and the first removal point. A line section of the feed line, which extends at least over the length from the first removal point to the last downward removal point of the assembly-side temperature control circuit, has an average line cross-section which is one of greater than a multiple of the average line cross-section of a supply line section arranged in the feed downstream of the temperature control device and arranged upstream of the line section, and which is greater than a multiple of a line a cross-section upstream of each of the largest return point.

Temperature control assembly for controlling the temperature of a functional parts of a printing machine, and printing system comprising at least one printing machine and a temperature control assembly

A temperature control assembly controls the temperature of parts of a printing machine. A plurality of assembly-side sub-circuits, the temperature of which is to be individually controlled, each comprises a temperature control fluid outlet and a temperature control fluid inlet. An external temperature control sub-circuit, can be connected to each assembly-side sub-circuit to form a respective temperature control circuit. The assembly-side sub-circuits are coupled to a common feed line, which conducts temperature control fluid, in a thermal and/or fluidic manner on the feed side to control the temperature of the assembly-side sub-circuits and to a common return line on the return side. The feed line is connected to a fluid store, which provides temperature control fluid to supply the feed line. The temperature control assembly comprises the common feed line, the fluid store, and an assembly which controls the temperature of the temperature control fluid of the fluid store.

Temperature control assembly for controlling the temperature of functional parts of a printing machine, printing system with a printing machine and a temperature control assembly, and set of modules for forming a temperature control assembly

A printing machine, which is configured as a printing tower having a plurality of printing units, is usable for double-sided, multicolor printing. A device that is usable for controlling the temperature of the components of one or more of the printing couples is provided. Each printing unit includes a plurality of printing towers that are disposed vertically one over the other. Each of these printing devices has at least one component that is to be temperature controlled and which has a thermal interaction with a fluid of a secondary circuit by way of an inlet. The secondary circuit can have fluid of a primary circuit entered by a feeding station for controlling the temperature. Components that are to be temperature controlled, and that are part of at least two different printing devices, have thermal interactions with two secondary circuits that are different from each other. A selectively actuable electrical heating appliance is provided in the secondary circuit in addition to the feeding station and at least one of valves and pumps and heating appliances that are associated with the two secondary circuits and different from each other are disposed on a machine front side at different heights or can be fed with fluid from the primary units by feeding stations that are disposed at different heights.
