AI Technical Summary

Benefits of technology

[0024]The heat conduction unit of the present invention is manufactured using a laminar implemented with a composite material of a high water absorbent fabric and a coated resin having a high moisture permeability and air shield ability, thereby improving the heat and moisture exchange performance with enhanced moisture permeability and water repellent effect while avoiding the contamination controversy caused by the reinforcement and absorbent materials used in the fabrication of conventional heat conductive unit.

[0025]Also, the heat conduction unit of the present invention is advantageous in product reliability and durability since the laminar of the heat conduction unit has improved water resistance even in the high temperature and high moisturized environment and improved air shield ability in comparison with the cellulose or fabric material to protect the mixture of the exhaust and intake airflows.

[0026]Also, the heat conduction unit of the present invention is advantageous in heat conductivity improved by applying micro fiber coated with metal fiber or metal itself such as silver fiber to the fiber fabric layer of the laminar. The addition of micro molecules such as nano-silver, carbon black, and carbon nano-tube to the high polymer molecules of the micro fiber fabric further improves the heat conductivity and provides antibacterial and bactericidal effects.

Problems solved by technology

Accordingly, the conventional laminar fabrication is carried out through complicated additional processes including reinforcement process and absorbent agent application process in addition to the basic shaping process, and these additional processes cause a environment contamination problems due to the toxicity of the additive materials.

Also, the conventional laminar is likely to have a low porosity due to the use of large amount of reinforcement agent, even though it may be compensated by the absorbance agent, which restricts the efficient moisture exchange performance of the laminar.

Particularly, the polypropylene (PP) laminar made of high polymer film material is inferior to the cellulose laminar in moisture exchange efficiency.

Also, the difference of thermal expansion rate between the cellulose and reinforcement material deteriorate the vulnerable water resistance of the laminar, thereby being fragile in a high temperature and high moisturized environment, resulting in degrading the product reliability.

However, this conventional laminar has a problem in that the exhaust and intake airflows are likely to be mixed due to its high air permeability.
