<p>The present invention relates to a functional heat transfer film, and more specifically, to a functional heat film capable of blocking air and increasing water vapor permeability. Provided is a heat transfer device comprising the same and: a film-shaped heat transfer layer comprising a polymer resin for the same; and a functional heat transfer film comprising a first filler formed at the heat transfer layer for increasing water vapor permeability. According to the present invention, it is possible to increase water vapor permeability of the polymer resin and reducing air penetration. Therefore, it is possible to effectively transfer heat by using sensible and potential heat and simultaneously manufacture a heat transfer device with excellent heat transfer efficiency by blocking air penetration.</p> |
