    • An anti-condensate resistance (1) with PTC thermistor is disclosed, comprising a central heat sink element (3), such central heat sink element (3) being composed of two dissipating plates (3a, 3b) which are mutually facing and continuously joined in such a way as to form, in a space interposed between the plates, an inserting housing (15) of the PTC thermistor together with a securing element (11), a first and a second closing plugs (7a, 7b) for closing openings of the inserting housing (15) and for hermetically sealing the PTC thermistor inside the inserting housing (15); the dissipating plates (3a, 3b) being equipped with a convex curvature towards their center, each one of the dissipating plates (3a, 3b) being equipped at their ends with inserting tracks (4a, 4b) forming working portions (6a, 6b) on which forces (F) are exerted which are adapted to permanently set joining hourglasses (4c) of the dissipating plates (3a, 3b) for cancelling or reverting the curvature and blocking the PTC thermistor in the inserting housing (15) and the closing plugs (7a, 7b) in the openings, and each one of the dissipating plates (3a, 3b) being equipped on an external surface with a plurality of dissipating wings (13); a process for assembling such anti-condensate resistance (1) is further described.
    • 本发明公开了一种具有PTC热敏电阻的抗冷凝电阻(1),其包括中央散热元件(3),该中央散热元件(3)由两个相互面对且连续接合的散热板(3a,3b) 以这样的方式在插入在板之间的空间中形成PTC热敏电阻的插入壳体(15)以及固定元件(11),第一和第二闭合插塞(7a,7b)用于闭合开口 插入壳体(15)内并且用于将PTC热敏电阻气密地密封在插入壳体(15)内; 所述散热板(3a,3b)在它们的端部装有形成工作部分(6a,6b)的插入轨道(4a,4b),所述散热板(3a,3b) (F)施加于其上的适于永久固定散热板(3a,3b)的接合沙漏(4c)的力(F),用于消除或恢复弯曲并阻塞插入外壳(15)中的PTC热敏电阻, (7a,7b),并且每个散热板(3a,3b)在外表面上装备有多个散热翼(13); 进一步描述用于组装这种抗凝结阻力(1)的过程。
