PURPOSE: A register of blower motor for heat exchanger is provided to smooth operation of the heat exchanger including the register. CONSTITUTION: A positive temperature coefficient(PTC) element(3) is installed so that a heat sink(2) is built in a main body(1) of a register. Film type resistors(4,5) are installed on one side of the PTC element and connected with the PTC element. A cover(7) is installed over the resistors and the PTC element with a heat sink(6) interposed to form a register. One side of the lowermost part, the resistor, is connected with a blower motor switch connected with a power source part. The uppermost part, the PTC element, is connected with a blower motor to control the blower motor.
