Radiator of resistance for blower {RADIATOR OF RESISTANCE FOR FAN}

According to the present invention, in the heat exchanger installed in the vehicle to adjust the indoor temperature of the vehicle, the generated air is blown to the interior of the vehicle by using the blower, so that the air volume is adjusted according to the driving of the blower, By using the heat generated when controlling the driving force of the blower during the control of the operation to operate the switch using a positive temperature coefficient (PTC) and the generation while smoothly driving the blower according to the operation of the switch The present invention relates to a heat radiation device of a blower for allowing heat to be radiated smoothly.

In general, a positive temperature coefficient (PTC) used in a heater or a resistor is a control element that stops heat generation by heat when a heater or a resistor is heated above a certain temperature. A positive thermistor , A device having characteristics that can be used to protect the circuit when the short circuit is resolved when the over current flows through the circuit due to a thermal sensor, a short circuit, etc. It is widely used for the control of, and the PTC element used as described above needs to dissipate its own heat generation and must not change its resistance value during the heat generation or heat dissipation action.

On the other hand, a blower installed in a conventional heat exchanger to blow the heat exchanged air is to adjust the air volume by the rotational speed and driving force, the blower motor to control the variable drive of the blower and to promote the stability of the drive A resistor having a resistor or a resistor is installed, and the resistor is provided with a terminal for connecting a power source. The resistor for the blower only serves to control the driving of the blower.

However, in the related art, high heat is generated in the coil or resistor for the resistance according to the driving and control of the blower, and in order to prevent the high heat, a heat dissipation heat sink is provided in the resistor or the like. There was not enough heat dissipation by heat sink, and even though the high heat was generated, there was a closed end that caused excessive load on the blower because the blower could not be controlled automatically. This could not be done, there was a problem such as risk of fire.

The present invention has been made in view of the conventional problems as described above, the present invention is installed in the vehicle to heat the heat exchanger to adjust the indoor temperature of the vehicle, by using the blower to blow the air to the interior of the vehicle The air volume is adjusted according to the driving of the blower, and the switch using the electric resistance element is operated by using heat generated when the driving force of the blower is controlled when the air volume is adjusted. It is intended to provide a heat dissipation device for a blower that can smoothly dissipate the generated heat while smoothly driving the blower, which will be described below in detail with reference to the accompanying drawings and examples.
