    Abstract: A heating drum, which guides a long-sized medium and also heats and dries the medium, includes a cylinder-shaped main body part, disc-shaped limb parts attached to the end parts of the main body part, and a shaft core attached to the limb parts. On an edge of an inner circumferential surface of the main body part, a cut-out part extending in the circumferential direction is formed. A groove part also extending in the circumferential direction is formed on the inner circumferential surface on an inner side from the cut-out part of the main body part. The cut-out part and the groove part are in parallel with each other, and the limb part is fitted to the cut-out part. A claw part is fixed to the limb part by a fitting tool, so that a hook part of the claw part is freely movably fitted to the groove part.

  • Publication number: 20080251238
    Abstract: A cooling device comprising a rotating part (1) provided with an internal space (3) intended for the transport of cooling liquid and provided with external fins (4) intended for the transport of gas along at least a section of the rotating part. The rotating part is symmetrical in rotation and revolves around an axis of rotation (2). The rotating part comprises a cooling liquid pump section (5), a fan section (6), and between these an intermediate section (7) arranged around the axis of rotation, where the fan section has a basic shape of a radially extended plate (15), wherein the flow of cooling liquid enters at the pump section from an object to be cooled, proceeds through the intermediate section and turns back in the vicinity of the periphery (17) of the fan section, in order to once again pass the intermediate section and then be pumped back to the object by means of the pump section.

  • Patent number: 7069928
    Abstract: A first and second housing is joined together by a middle housing rotatable with respect to the first and second housing. The first and second housings have conduits passing through exterior walls and an annular ring on an inside wall together with an annular interior edge rotatably joined to first and second side rim channels of the middle housing. A heat-moisture exchanger material having an annular opening through which a tube passes is mounted within the middle housing so that in a first rotatable position air and moisture passes through the first and second housing conduits directly and in a second rotatable position must pass through the heat-moisture exchange material.

  • Patent number: 7063128
    Abstract: A drum type heat exchanger for effectively ventilating and purifying room air of a factory, a building or a house and the like is described. The drum type heat exchanger has heat transfer means with a drum shape and thus an entire size is reduced as much as possible and become compact, such that a handling and an installation is easy, a thermal efficiency to an installation space of the heat transfer means is maximized, and overall maintenance and repair such as a check or exchange of the heat transfer means are easy. Additionally, the drum type heat exchanger uses a drum with a short radius of rotation so that an entire operation cycle time is shortened and a heat transfer area is sufficiently secured in order to keep the thermal efficiency high.

    Abstract: The present invention is directed to a drum type heat exchanger for effectively ventilating and purifying room air of a factory, a building or a house and the like. The present invention provides a drum type heat exchanger in which heat transfer means has a drum shape and thus an entire size is reduced as much as possible and become compact, such that a handling and an installation is easy, a small space is taken for the installation, a thermal efficiency to an installation space of the heat transfer means is maximized, and overall maintenance and repair such as a check or exchange of the heat transfer means are easy in order for the heat transfer means to be recycled and thus a life span of the heat exchanger is extended. Additionally, the present invention provides the drum type heat exchanger which uses the drum with a short radius of rotation so that an entire operation cycle time is shortened and a heat transfer area is sufficiently secured in order to keep the thermal efficiency high.

  • Patent number: 6683284
    Abstract: A thermal roll for efficiently transferring heat to or from a web is provided. The thermal roll includes a rotatable outer shell having a cylindrical outer mantle and a stationary inner shell within the rotatable outer shell. An annular space is defined between an inner surface of the rotatable outer shell and an outer surface of the stationary inner shell. The annular space of a relatively low volume is filled with a heat exchange fluid, such as oil or water, that exchanges heat with a fibrous web through the mantle of the rotatable outer shell. The low volume of the annular space enables high heat transfer rates to the web and quick and efficient changes to the temperature of the heat exchange fluid. The thermal roll is adaptable for use as various types of rolls, such as calender rolls, press rolls, drying cylinders, and Yankee cylinders.
