[Industrial use]

The present invention relates to a structure of a reservoir tank for receiving an excess coolant in a forced water cooling device for cooling an engine of a vehicle, and very efficiently discharges steam generated when the coolant is overheated during operation, and consumes coolant when overheated. This is to prevent a decrease in cooling efficiency.

[Prior art]

In general, when the coolant is overheated in the forced water cooling system of a car, the high temperature and high pressure water introduced into the upper tank of the radiator is introduced into the reservoir tank along the overflow pipe by opening the pressure valve provided in the radiator cap. In steam, water, except water, is discharged to the outside through the steam outlet above it.

However, if the superheat continues for a long time, since a large amount of steam escapes from the coolant continuously flowing into the reservoir tank, only a small amount of coolant remains on the coolant circuit of the engine body, causing serious deterioration of cooling performance.

[Problem to Solve Invention]

Therefore, the present invention has been made to solve the problem in view of the above problems as a first object of the present invention to discharge the steam reached to the reservoir tank more quickly, the second object is that before the steam is discharged out It is to prevent the loss of cooling water by separating the water contained in the steam and collecting it back into the reservoir tank.

[Means to solve the problem]

And a characteristic configuration for this is that the coolant sent to the cylinder block and the cylinder head of the engine by the pump cools the engine back to the radiator, the excess water that is overflowed as the cooling water is expanded is stored in the reservoir tank In a conventional cooling apparatus, the first tank having a lid on one side of the upper side, the outlet pipe on the lower side of the lower side, the motor is mounted on the bottom of the bottom, and the lower half is built in the first tank. At least one wire mesh type water separator in communication with the first tank and having an inlet pipe extending through the side of the first tank, the second tank having a steam outlet thereon, and an internal suspension of the second tank. Is formed horizontally, and the impeller provided above is constituted by a discharge mechanism in which the impeller is driven by the motor as described above. It is to be quickly discharged by the water and the moisture of the discharged vapor is collected by the wire mesh type separator to remain in the second tank.

EXAMPLE

Hereinafter, according to the accompanying drawings, the detailed configuration and effect of the present invention will be described.

1 is a system diagram showing a cooling device of an automobile engine, and a radiator 1 in the center portion, an engine 2 on the right side, and a reservoir tank 3 of the present invention can be seen on the left side, and a pump for circulating water ( 4), the thermostat 5 for controlling the flow of water is provided.

In the upper cap 11 of the radiator 1, the overflow pipe 12 is connected to the reservoir tank 3 so that excess water is allowed to flow, and the lower part of the radiator 1 is lowered from the lower end of the reservoir tank 3. There is a return flow pipe (13) is connected to be able to replenish the water again, so far is similar to the existing cooling device.

The present invention is provided with the solenoid valves 61 and 62 which are operated by the ECU 6 at the interruption of the bore flow pipe 12 and the return flow pipe 13, respectively, and also have a new reservoir tank ( 3) is characteristic.

In the reservoir tank 3 of the present invention, the first tank 3A has a lid 31 on one side of the upper side, and the return flow tube 13 is connected to the bottom of the radiator 1 on the lower side of the side. The motor 7 is attached to the center part.

In addition, therein, the upper tank having the steam outlet 32 is projected outward, and the second tank 3B of the type having the lower half embedded therein is integrally coupled, and a plurality of through holes 33 are drilled in the lower half thereof. The overflow tube 12, which is in communication with the first tank 3A and extends through the side of the first tank 3A, is connected to the side of the second tank 3B from the top of the radiator 1, have.

On the other hand, the upper end of the second tank (3B) is provided with a steam discharge mechanism (8), which is formed at least one wire mesh type water separation plate (81, 82) horizontally, these wire mesh type water separation plate Directly above the 81 and 82, an impeller 83 is installed to be driven by the motor 7, which is also operated by the ECU 6, and the solenoid valve described above. Further necessary and necessary for the 61 and 62 and the motor 7 to be operated by the ECU 6 are the pressure sensor 63 and the negative pressure sensor 64 provided on the upper part of the radiator 1, which are predetermined It is supposed to work by value.

In the figure, reference numeral 34 is a guide tube for vapor discharge.

The following describes the operating state of the present invention configured as described above.

As shown in FIG. 1, the water in the radiator 1 passes through the cylinder block 21 and the cylinder head 22 of the engine 2 by the operation of the pump 4 as shown in FIG. 1. When the heat exchange takes place at the time, the hot water is cooled again by passing through the radiator 1 and supplied to the engine 2 by the pump again.

At this time, the flow of the cooling water is controlled by the thermostat 5 and when the engine is overheated and the temperature of the water gradually increases, the volume expands, and the pressure sensor 63 detects the pressurized state to detect the ECU 6. Since the solenoid valve 61 is opened through, the excess water passes to the reservoir tank 3 of the present invention through the overflow pipe 12.

That is, as shown in FIG. 2, the second tank 3B flows into the second tank 3B through the overflow tube 12, and most of the water is composed of combustion gas and blow-by gas, which are generated around steam or the combustion chamber. This is a state of high temperature and high pressure, so as to quickly rise by the driving of the impeller 83 in the upper portion of the second tank in this process one or more wire mesh type moisture separator plate 81 provided in the middle portion of the second tank (3B) There is (82), so that water vapor condenses, so that unnecessary gas and water vapor go out, and some fall and remain as water again.

The falling water always returns back to the radiator 1 through the return flow pipe 13 connected to the side of the first tank 3A.

After this process, when the coolant returns to the negative pressure state, this time, the negative pressure sensor 64 detects this, and again, the solenoid valve 61 of the overflow pipe 12 is blocked and returned through the ECU 6. The solenoid valve 62 of the flow pipe 13 is opened so that the coolant of the reservoir tank 3 can be supplied to the radiator 1 again.

[Effects of the Invention]

The present invention as described in detail above is forcibly discharged to the impeller 83 of the second tank (3B) instead of releasing steam that occupies most of the surplus water that has passed to the reservoir tank (3) in a superheated state. Since most of the water is retained again by the wire mesh type moisture separator plates 81 and 82 provided below, the evaporation of water can be suppressed as much as possible while quickly discharging the superheated steam. The primary effect of suppressing overheating by quickly discharging the generated steam, and also because it can continuously supply more water into the engine, the secondary effect can be seen again.

In conclusion, the radiator 1 prevents damage, promotes thermal protection of the engine accessories, and has the effect of maximizing the turbulence performance.
