    摘要： Method for controlling heat transfer between a mainly solid base and the ambient medium
    This invention belongs to the field of construction of shielding and heat-shielding structures. The technical result is changing the degree of useful effect from the regulation of heat transfer depending on the temperature of the plates of the heat control structure.
    In the method for regulating heat transfer between a mainly solid base and ambient medium, one plate (2) or at least two plates (2, 5) stacked in layers and interconnected are installed on base (1) at rest temperature, while at least one (2) of the said plates, when its temperature changes relative to the rest temperature, is capable of deforming so that a cavity is formed between this plate and the base or the plate adjacent in the layer, filled with particles of the ambient medium, and fixation points (3) of plate (2) to base (1) or plate (5) adjacent in the layer are selected so that this plate (2) takes a convex shape during deformation.

    摘要： Presently disclosed thermal actuators may be incorporated into a self-regulating thermal insulation, such that expansion and contraction of the thermal actuators in response to changes in temperature adjacent the thermal insulation automatically changes the thermal resistance of the thermal insulation. In this manner, a self-regulating thermal insulation may be configured to locally adjust in response to local changes in temperature of a part being insulated, for example, during curing or some other manufacturing process. Such self-regulating thermal insulation may be configured to respond to temperature changes without feedback control systems, power, or human intervention. One example of a thermal actuator may include a first segment of a first material, and a plurality of second segments of a second material, the second segments being coupled to the first segment and spaced apart from one another along the length of the first segment.

    摘要： Method for controlling heat transfer between two objects. In one embodiment, the method includes providing a first current through a first electromagnet disposed about a container holding magnetorheological fluid to generate a first magnetic field such that particles in the magnetorheological fluid align with the first magnetic field to conductively couple a first conductive element to a second conductive element; and providing a second current through a second electromagnet disposed perpendicular to the first electromagnet to generate a second magnetic field perpendicular to the first magnetic field such that the particles in the magnetorheological fluid align with the second magnetic field to conductively uncouple the first conductive member from the second conductive member.

    摘要： Method and apparatus for controlling heat transfer between two objects. In one embodiment, an apparatus for controlled heat transfer is disclosed herein. The apparatus includes a first and second conductive elements, a container of magnetorheological fluid disposed between the first and second conductive elements, an electromagnet disposed about the container, wherein the electromagnet is configured to produce a magnetic field within the container of magnetorheological fluid and conductively couple the first and second conductive elements, and at least one biasing element wherein the biasing element is coupled to the first conductive element and is configured to move the first conductive element relative to the container to conductively couple and uncouple the first conductive element and the second conductive element.
