Abstract: A heater unit for a respiratory system is designed for natural convection cooling air to pass first through a transformer in the heater unit and then through a heat sink in the heater unit to which is mounted a power switch to conduct heat from the power switch to the cooling air passing through the heat sink. A thermal break may be provided between the heat sink and the transformer. The transformer may be a toroidal transformer with the air passing through an aperture thereof such as from a hollow projection of the heater unit extending into the aperture. One side of the transformer may be situated along a surface of the heater unit and the heat sink secured to the heater unit against the opposite side of the transformer to hold the transformer in place. A venting chamber may be associated with an air exhaust of the heater unit to provide a circuitous exit path for air exiting the heater unit. The venting chamber may extend in generally surrounding relationship with the heater of the heater unit.

Abstract: A pulse transformer arrangement (100) is built from an uncut pulse transformer core (110) and at least one foil winding (120-A, 120-B) (each) comprising multiple insulated conducting strips arranged around the core and ending in foil winding terminals to form multiple independent primary windings. This new design principle has several advantages. Making the winding(s) of foil eliminates the need to cut the core, because of the ease of insertion of the foil winding(s) onto the core. The work to set up a plurality of primary windings is significantly reduced. In addition to the elimination of the costs for cutting the core, this also brings the further advantages of reduced DC reset current, reduced risk for electrical shorts and avoidance of excessive losses due to potential high frequency AC resistance problems.

Abstract translation: 脉冲变压器布置（100）由未切割的脉冲变压器芯（110）构成，并且至少一个箔绕组（120-A，120-B）（每个）包括布置在芯周围并以箔绕组结束的多个绝缘导电条 端子形成多个独立的初级绕组。 这种新的设计原理有几个优点。 由于易于将箔绕组插入到芯上，使得箔的绕组消除了切割芯的需要。 设置多个初级绕组的工作显着减少。 除了消除了切割核心的成本之外，这还带来了降低直流复位电流，降低电气短路风险和避免由于潜在的高频交流电阻问题引起的过大损耗的进一步优势。
