摘要： A desk top sealer includes three compartments for housing a solenoid assembly, a power supply and a circuit board, respectively. A source of air flow flows into an initial compartment and is channeled through apertures in brackets forming the two remaining compartments for cooling purposes and is exhausted from each compartment through a base. The circuit board, upon actuation, provides RF energy to a fixed ceramic/metal jaw to heat and weld plastic tubing clamped to the fixed jaw by a movable jaw at ground potential. The movable jaw is guided during translation by a pair of rods extending from a face plate, which rods also prevent rotation of the movable jaw about its axis of translation to maintain the movable jaw in alignment with the fixed jaw. The movable jaw is relatively massive to serve as a heat sink for the heat of the tubing being welded and includes a substantial surface area to dissipate to the ambient environment any heat buildup that may occur. A face plate, supporting the fixed and movable jaws, is configured to prevent flow of fluid from a burst tubing into the sealer and the face plate may house indicator lamps providing lights reflective of the operation being performed, which lights are visible through a translucent part of the face plate.
