摘要:
Sheet-shaped heater, in particular for use as a bed heater, and a water bed heater respectively. When designing such heaters it is difficult to obtain an optimal combination of properties for satisfying the different requirements imposed, inter alia with respect to reliability and safety, uniform temperature distribution and mechanical flexibility. For heat distribution the element comprises a continuous metal foil (22) in which there is formed a continuous meandering groove (20) which lies substantially at one side of the plane of the metal foil. There is no thickness reduction of the metal foil at the groove (20) formed. A heat emitting conduit, preferably a heating cable (21a-c) is tightly received in the groove, the depth thereof being substantially equal to the transverse dimension of the conduit. An outer protective layer (23) is tightly joined to the metal foil (22) and preferably to a portion of the surface of the conduit (21a-c) at that side where the groove (20) is open.

片状加热器,特别是用作床加热器,以及水床加热器。 当设计这种加热器时,难以获得满足不同要求的性能的最佳组合,特别是在可靠性和安全性,均匀的温度分布和机械柔性方面。 为了分配热量,元件包括连续的金属箔(22),其中形成有基本上位于金属箔的平面的一侧的连续的曲折槽(20)。 在形成的凹槽(20)处没有金属箔的厚度减小。 发热管道,优选加热电缆(21a-c)被紧密地容纳在槽中,其深度基本上等于导管的横向尺寸。 外保护层(23)紧密地接合到金属箔(22)上,优选地连接到凹槽(20)打开的那侧的导管(21a-c)的表面的一部分。
