THERMAL ELEMENT, THERMAL COVER, METHOD AND DEVICE FOR MANUFACTURING A THERMAL ELEMENT

摘要

The invention relates to a thermal element (1) for accumulation and emission of thermal energy for thermally influencing the environment. Each element consists of at least two plastic films (2, 3), connected with each other along elongated continuous connecting seams (4-12). Between them they delimit a multitude of reservoir spaces (14), filled with a fluid functioning to accumulate and emit thermal energy to the environment through the plastic films. A first set of connecting seams (4-8) extends in spaced relationship, and a second set of elongated connecting seams (9-12) extends in spaced relationship and crosses the first set of seams. Hereby, the reservoir spaces between the seams are sealed off.
