The present invention is an apparatus for removing impurities in a vehicle cooling system, and more specifically, to a device for completely discharging cooling water from a vehicle cooling system and removing impurities such as rust, scale, or oil formed in the cooling system. It is about.

In engines such as automobiles, the cylinder block and the cylinder head are cooled by using coolant to cool heat generated by combustion, and the auto transmission oil is also cooled by coolant.

The inside of the cooling system composed of metal is exposed to the environment of high temperature and high humidity, and for this reason, the corrosion of the cooling system occurs rapidly.

Therefore, the cooling water is added to prevent corrosion of the cooling system, and in addition to the various chemical additives such as lubricants and antifoams.

Due to the complicated shape of the cooling system, 40 to 50% of the total coolant is It will not be exchanged.

As a result, the cooling system is not sufficiently exchanged with the cooling water, so the required amount of the corrosion inhibitor is insufficient, resulting in the deterioration of the quality of the cooling water, the rapid corrosion of the cooling system, and the deterioration of the cooling efficiency.

In the present invention, the impurity removal device 1 includes a cooling water storage tank 10, a pulsation pump 20 connected to the cooling water storage tank 10, and a three-way valve 30 connected to the pulsation pump 20. And a cooling system 100 connected to the three-way valve 30, a cooling water recovery line 40 for recovering the cooling water from the cooling system 100 and recovering the cooling water to a cooling water storage tank, and the cooling water recovery line ( And a cooling water discharge line 60 branched and formed at 40 and a control unit 70 for controlling the recovery line and the discharge line.

The motor 10a is connected to the cooling water storage tank 10 so that the amount of cooling water is insufficient during the removal of impurities, or impurities such as rust are removed, and the second washing operation is performed with clean water to remove the residues remaining in the cooling system 100. When it serves to supply the cooling water to the storage tank (10).

The float water level sensor 10b is attached to the cooling water storage tank 10, and when the amount of cooling water is insufficient, a signal is sent to the controller 70 to drive the motor 10a to replenish the cooling water.

The pulsation pump 20 is a pump for generating pulsation in the cooling water supplied to the cooling system 100, and an electric diaphragm type or an air diaphragm type pump may be used. The pressure supplied to the cooling system 100 is controlled by controlling the rotational speed of the pump in the electric type, and by adjusting the amount of air flowing into the pump in the air type, and this control is performed by the controller 70 connected to the pulsation pump 20. Is done through.

The pulsation pump 20 is connected to the engine 103 of the cooling system 100 through a three-way valve 30, wherein the cooling water supply direction is connected to coincide in the forward direction in which the cooling water circulates in the engine 100. It effectively removes rust, scale and oil sludge from inside.

That is, the three-way valve 30 is the first valve 30a is connected to the pulsation pump 20, the second valve 30b is connected to the upper side of the cooling radiator 101, the third valve (30c) Is connected to the supply side of the heater heat exchanger 102, and is controlled to open and close in each direction by the control unit 70.

The cooling system 100 includes a cooling radiator 101 having an upper side connected to a second valve 30b side of the three-way valve 30, and an engine having a lower side of the cooling radiator connected to a water pump 103b side. 103 is connected to the lower side cooling line of the engine 103 and the other end is connected to the third valve 30c side of the three-way valve 30 to supply the coolant to the engine 103. 102).

The thermostat mounted on the upper part of the engine 103 is removed, and the thermostat port 103a is connected to the coolant recovery line 40 through the coolant discharge line 104.

The cooling water recovery line 40 is connected to the cooling water storage tank 10, and a recovery line valve 41 is provided in the middle of the cooling water recovery line 40.

Upstream of the recovery line valve 41, a cooling water discharge line 60, which is branched from the cooling water recovery line 40 and provided with the recovery line valve 61, is formed.

The controller 70 controls the motor 10a, the three-way valve 30, the recovery line valve 41, the discharge line valve 61, the pulsation pump 20, etc. according to the operation mode input from the operation unit 80. It works.

The operation unit 80 is configured to operate in a rust removal mode, an oil cleaning mode, a discharge mode, a coolant (antifreeze) filling mode for removing impurities, and is configured to adjust an operating time and the like. In the embodiment of the present invention has been described with respect to the configuration for controlling the operation unit electronically, of course it is also possible by manual operation.

Hereinafter, the operation of the first embodiment of the present invention will be described.

When the rust removal mode is operated by the operation unit 80, the control unit 70 simultaneously opens both the cooling radiator 101 side valve 30b and the heater heat exchanger 102 side valve 30c of the three-way valve 30. By opening the return line valve 41 and closing the discharge line valve 61, the coolant is returned via the coolant return line 40 via the coolant storage tank 10, the pulsation pump 20, and the cooling system 100. It is operated with a closed system that is returned to the cooling water storage tank (10).

Cooling water to which the pulsating wave is applied by the pulsation pump 20 passes through the three-way valve 30 and simultaneously acts on the cooling radiator 101 and the heater heat exchanger 102, thereby cooling the radiator 101 and the heater heat exchanger 102. ) And impurities, such as rust, scale, oil sludge, etc. adhered to the inner surface of the cylinder block or head of the engine 103.

After the rust removal mode is performed for a predetermined time, when the discharge mode is operated to discharge the coolant mixed with impurities, the control unit 70 closes the recovery line valve 41 and opens the discharge line valve 61 to cool the coolant. Through the storage tank 10, the pulsation pump 20, the cooling system 100 is operated as an open system discharged to the outside through the cooling water discharge line 60.

Even when the discharge mode is performed, the cooling water is discharged while applying the pulsation by the pulsation pump, thereby effectively discharging the rust removal residue contained in the cooling water.

Then, the cooling water is sufficiently replenished in the cooling system in which the inside is sufficiently empty by the cooling water (antifreeze) filling mode. In the filling mode operation, the control unit 70 performs the predetermined time with the recovery line valve 41 closed and the discharge line valve 61 open, and then the cooling water is discharged to the discharge line 60. If detected, the discharge line valve 61 is closed.

The point of efficient removal is different from that of the first embodiment.

In addition, it is possible to filter the impurities in the cooling water by the filter 50 to supply cleaner cooling water to the cooling system, and that the impurities are removed by configuring the filter 50 in a transparent housing and placing the filter 50 outside the removal device 1.
