Provided is a cooling module including a reservoir tank in which cooling water is stored, a screw pump coupled to the reservoir tank and having a cooling water inlet communicating with the reservoir tank to pump cooling water, and a direction control valve coupled to the reservoir tank, having an outlet port communicating with the reservoir tank, and having a plurality of inlet ports to change a direction of flow of cooling water according to an operation, so that efficiency corresponding to the use of a plurality of centrifugal pumps of the related art may be achieved by using a single screw pump, thereby reducing the number of parts and simplifying a package, while simplifying the configuration.

Integrated cooling module

A motor integrated with a control unit having an efficiency in cooling by allowing the heat generated by the motor to be radiated away from the motor. Heat generated from the control unit is separately radiated away from the control unit. The motor integrated with the control unit can be utilized in water pumps.

Motor integrated with control unit and water pump having the same

A strainer for a fuel pump according to the present invention includes: a communicating pipe including a flow path formed to communicate with a fuel inlet of the fuel pump; a filter including an internal space in which a fuel flows and coupled to the communicating pipe so that the internal space communicates with the communicating pipe; and a rib disposed in the filter and coupled to the communicating pipe, in which the filter includes a first filtering portion extending in a length direction with respect to the communicating pipe, a connecting portion extending in a width direction at an edge of the first filtering portion, and a second filtering portion extending in the length direction at the connecting portion and spaced apart from the first filtering portion in the width direction. Therefore, the strainer may have a relatively large filtering area and a small size.

Strainer for fuel pump

Provided is a brushless direct currency (BLDC) motor and a manufacturing method thereof, and more particularly, a brushless direct currency (BLDC) motor including a rotor rotated to drive an impeller and capable of reducing a defective rate of the motor due to a rotational imbalance by controlling a shape of a magnet portion included in the rotor, and a manufacturing method thereof.

Brushless direct currency (BLDC) motor and manufacturing method thereof

Provided is a complementary apparatus for measuring a level of urea water includes an ultrasonic measurement unit installed inside a urea water tank to measure a level of urea water using an ultrasonic wave, an inductance measurement unit including a winding coil wound in a vertical direction inside the urea water tank and having a winding density varied toward one side, and measuring a level of urea water using inductance measured as a current is applied to the winding coil, a temperature measurement unit installed in the urea water tank and measuring a temperature, and a controller determining whether to operate the ultrasonic measurement unit or the inductance measurement unit according to the temperature measured by the temperature measurement unit or selectively outputting a level of urea water measured by the ultrasonic measurement unit and the inductance measurement unit.

Complementary apparatus for measuring urea water level

Provided is a liquid level sensor for a fuel tank including: a case having a filled liquid filled therein and closed; a resistor substrate provided in the case and a wiper contacting the resistor substrate; and a damper provided in the case and absorbing a pressure change of an inner portion of the case. The liquid level sensor for a fuel tank is configured to absorb a pressure change of the inner portion of the case, thereby making it possible to prevent leakage of the filled liquid that may occur due to the pressure change of the inner portion of the case.
