| 摘要 |
The present invention relates to a plate type heat transfer device which has a n umber of rectangular or oval cavities (or cells) in its cross-section, charged with a certain amount of a working fluid in each of the cavities (or cells) where heat from the lower surface of the plate is transferred to the upper surface of the heat trans fer device. Therefore, the plate type heat transferred device has a wide range of application such as for the stabilization or protecti on of foundation for pipelines, roads, airport run-way, structures etc. by keeping the foundation intact in extremely cold regi ons, 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.
