Heater module for filter assembly
摘要：
A heater module (10) for heating a flow of fluid employs a base member and a cap (16) molded from polymeric material, defining a cavity. First (70) and second (80) flow distributor plates composed of electrically and thermally conductive material are positioned in the cavity creating multi-tier first (37), second (66) and third (64) flow paths. A pair of PTC pills (12) mounted between the distributor plates (70,80) heat the distributor plates. The fluid is heated by contact with the PTC piles (12) and the distributor plates (70,80) as it passes through the first (37), second (66) and third (64) flow paths. A weir maintains a fluid level in the module to ensure that the PTC pills (12) are always covered by fluid. A dam splits the flow and directs it toward the PTC pills (12) after which the flow recombines.
摘要（中）：

用于加热流体流的加热器模块（10）采用基部构件和由聚合物材料模制而成的帽（16），所述帽限定空腔。 由导电和导热材料构成的第一（70）和第二（80）流量分配器板位于空腔中，从而形成多层第一（37），第二（66）和第三（64）流动路径。 安装在分配板（70,80）之间的一对PTC丸（12）加热分配板。 当流体通过第一（37），第二（66）和第三（64）流动路径时，流体通过与PTC桩（12）和分配板（70,80）接触而被加热。 堰保持模块中的液位以确保PTC药丸（12）始终被流体覆盖。 水坝将水流分开并将其导向PTC药丸（12），之后水流重新结合。
