Methods and systems of actively cooling a card while the card is within a card processing machine are described. One or more cooling stations are provided within the card processing machine to actively cool the card prior to performing a processing operation, during a processing operation, and/or after a processing operation on the card in order to reduce a temperature of the surface of the card.

The present disclosure describes systems and methods to provide electrode cooling for material surface treatment systems. A cooling fluid is employed to cool electrodes with a high voltage applied. For example, a conduit conveys a cooling fluid through the electrode, as the conduit also provides electrification for the electrode by being connected to an electrical power source. Further, cooling is implemented by use of a voltage isolator disposed between the conduit and a reservoir, with the voltage isolator providing a pathway to a reference voltage for residual electric charge from the cooling fluid passing through the voltage isolator.

A printing apparatus includes a cooling system for cooling a print medium. The cooling system includes a cooling member with a support surface configured for supporting the print medium. The cooling member has a first end and a second end and the support surface extends in a lateral direction between the first end and the second end. The cooling member is provided with supply channels and return channels extending between the first and the second end. A fluid circulation means supplies fluid through the supply channels from the first end to the second end, and back through the return channels from the second end to the first end.

A cooling device includes a cylindrical body having thermal conductivity, a plurality of thermoelectric converters, and a feeder cable. The plurality of thermoelectric converters are arranged along a periphery of the cylindrical body and disposed dispersedly along an axis of the cylindrical body. The feeder cable connects two or more thermoelectric converters arranged along the periphery of the cylindrical body in series among the plurality of thermoelectric converters to form each of a plurality of sets of thermoelectric converters. And the feeder cable forms a circuit for power feeding of the each of the plurality of sets of thermoelectric converters. A voltage is applied individually to each of circuits that includes the circuit so that thermoelectric converters of the each of the circuits in the plurality of thermoelectric converters are driven.

An image based correction system compensates for the image quality artifacts induced by thermal ghosting on evolving imaging member surfaces. With thermal ghosting directly tied to previous image content, a feed forward system determines thermal ghosting artifacts based on images previously rendered and generates an open loop gray-level correction to a current image that mitigates undesirable ghosting. For example, the correction system compensates for the thermal ghosting by making the current image lighter in areas that will be imaged onto warmer blanket regions, thereby cancelling out TRC differences between different temperature regions. A temperature sensor is used to measure the temperature of the imaging blanket due to the stresses induced by the image. This data is used to learn the parameters of the temperature model periodically during operation, and used in subsequent corrections to mitigate thermal ghosting in spite of changes in blanket properties over use and time.

A thermoelectric conversion unit includes a cylindrical body made of a thermally conductive material, a plurality of thermoelectric converters disposed on an inner peripheral surface of the cylindrical body, a heat transfer member, and a heat pipe installed in the heat transfer member. Each of the plurality of thermoelectric converters has an operating surface facing the inner peripheral surface and an inversely operating surface positioned at a side opposite to the operating surface. The heat transfer member is disposed on the inversely operating surface. Heat transfers between each of the plurality of thermoelectric converters and the heat transfer member via the inversely operating surface. The plurality of thermoelectric converters are divided into a plurality of sets of thermoelectric converters, and the heat transfer member and the heat pipe are provided for each of the plurality of sets of the thermoelectric converters. The heat pipe is disposed, in the heat transfer member, along positions of respective thermoelectric converters included in each of the plurality of sets of the thermoelectric converters.

An upper platform with a cooling device includes an upper platform, a heat insulation layer and a heating layer. A cooling layer having a cooling medium is disposed between the upper platform and the heat insulation layer. A working method of the upper platform with the cooling device includes that the coolant continuously flows into the cooling medium inlet, circulates in the pathway of the cooling layer, and then flows out of the cooling medium outlet. The advantages of the present invention include (1) the heat transmission from the heating layer to the upper platform is further reduced, which decreases the heat deformation of the upper platform and the relevant parts thereof, ensures the stability of equipment, and improves the precision of hot stamping and other processes of the equipment; and (2) the present invention is simple in structure, easy to be realized and convenient in operation.
