Air flow around blower resistor and at evaporator

摘要

A climate control system includes a compressor that circulates fluid between a condenser and an evaporator, an electric motor that drives a blower that includes a quantity of fan blades, and a duct fluidly coupling the blower and the evaporator. The blower forces air through the duct to the evaporator. A resistor is in electrical communication with the motor and has a quantity of fins extending into the passage of the duct. The duct may include a contoured wall that bulges outward and away from the resistor fins to enlarge a volume of the duct adjacent or beside the quantity of fins to allow a first portion of the air from the blower to flow around the fins while a second portion of the air cools the fins.
