Plate type heat transfer device
 A plate type heat transfer device which has a number of rectangular or oval cavities (or cell) in its transverse cross-section, is charged with a certain amount of a working fluid in each of the cavities (or cells). Heat from the lower surface of the plate is transferred to the upper surface of the heat transfer device. The device has a wide range of application, such as for the stabilization or protection of foundation for pipelines roads, airport runways, structures, etc., by keeping the foundation intact in extremely cold regions, or to the ceilings or floors of relatively large spaces, such as office buildings, manufacturing factories, storage buildings, or even to the roofs of refrigerator cars where the temperature control is required.
