Description

{THERMOSTAT HEATING PIN MANUFACTRING APPARATUS}

The present invention relates to a thermostat heating pin manufacturing apparatus for cooling an automobile engine, and more particularly, to a thermostat heating pin manufacturing method in which a connection wire is provided between a heating fin and a connection terminal, and a support molding is provided on an outer circumference of the connection wire. To manufacture a fin.

1 is a schematic view of an automobile engine cooling apparatus.

Generally, an engine cooling apparatus of an automobile includes a radiator 1, a water pump 2, and a thermostat 4.

A radiator 1 is provided between the engine 7 and the water pump 2 and functions to dissipate the engine cooling water discharged from the engine 7. [

A water pump (2) serves to circulate the engine cooling water to the engine (7) and the radiator (1).

The thermostat 4 is provided between the engine and the radiator and serves to supply the engine coolant to the radiator 1 when the temperature of the engine coolant exceeds a predetermined temperature.

In FIG. 1, reference numeral 3 denotes a radiator fan, reference numeral 5 denotes an air conditioning system, and reference numeral 6 denotes a heater switching valve.

In the automotive engine cooling apparatus, the thermostat 4 controls the flow of cooling water to regulate the temperature of the engine.

That is, if the temperature of the cooling water is a low temperature of a certain temperature (for example, 70 to 90 DEG C) or less, circulation to the radiator 1 is suppressed to warm up the engine 7 within a short time, Thereby preventing overheating of the engine.

The thermostat 4 is a pellet type or a bellows type in which the effect of water pressure is small and the temperature can be accurately controlled.

Fig. 2 (a) is an illustration of a pellet type thermostat, and Fig. 2 (b) is an example of a bellows type thermostat.

In the case of the pellet type thermostat, the wax charged in the pellet expands or shrinks according to the temperature of the cooling water, and the valve moves in the forward or backward direction or in the lateral direction in accordance with the expansion or contraction of the wax, Thereby opening and closing.

On the other hand, since the thermostat for cooling an automobile engine opens and closes the valve according to the expansion or contraction of the wax, if the temperature of the wax is increased, the valve can be opened even if the temperature of the cooling water is low.

In many cases, a heating pin is provided inside the pellet to accelerate the reaction speed of the wax. In this case, the operation of the heating pin is controlled by the engine control unit (ECU).

The following Patent Document 1 discloses a thermostat for cooling an automobile engine having a heating pin.

In the following Patent Document 1, the heating element corresponding to the heating pin can heat the thermostat operation member regardless of the cooling water temperature, and as a result, the valve driving portion can be controlled. Depending on the operation state of the engine, The output signal from the ECU makes it possible to open the valve quickly when the cooling water temperature becomes high, for example, when the engine load becomes large, or to control the engine itself by cooling the engine by increasing the lift amount more than usual .

In recent years, a technique has been developed in which the heating pins are integrally molded into a thermostat housing made of plastic.

If the thermostat heating pin is integrally molded into the thermostat housing, the thermostat can be manufactured more easily, which can greatly reduce the cost, and the thermostat operation can be performed more smoothly, so that the quality of the thermostat Can be greatly improved.
