BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a preheater for automobiles, and more particularly, to a preheater capable of quickly removing the defrost of the vehicle glass during cold start of an automobile.

The car's air conditioning system provides the passengers with a comfortable car interior, regardless of external weather conditions. Such an air conditioning device is a ventilation device that supplies air from the outside of the vehicle to the inside of the vehicle, a cooling device to remove moisture from the inside of the vehicle during the summer or rain, and to lower the temperature inside the vehicle, and a heating device to raise the temperature inside the vehicle during the winter. It consists of.

In general, the engine temperature rises to about 300 ° C. in the state in which the engine is preheated, and when the coolant circulates around the engine to cool the engine, the temperature of the coolant rises to about 100 ° C. or more.

The heating device of the vehicle air conditioning system circulates around the engine as described above, and the heat of the cooled coolant is heat-exchanged in the radiator, and is operated by blowing the warmed air to the air duct using a blower fan.

However, in winter, when the heating system is operated, if the so-called cold start that starts the engine of the vehicle in a completely cooled state requires an engine warm-up time of about 5 minutes or more, and is also cold to sufficiently heat the radiator. It will take about 10 minutes or more from start up. Therefore, vehicle occupants must stay within a cold vehicle for at least 10 minutes in winter.

Also, in winter, so-called 'sexuality' occurs when water in the air freezes as it sticks to the surface including the glass of automobiles. In particular, if the car's glass is sexually disturbed, it interferes with the driver's vision, so it must be removed to drive the car.

In order to remove the defrost, a method of operating the vehicle air conditioner to guide the air duct to the vehicle glass, and then transferring warm air from the radiator to the vehicle glass and melting it is mainly used. However, since the warm air is not generated before the radiator is sufficiently warmed, there is a problem of waiting about 10 minutes to remove the defrost.

In order to solve the inconvenience of the occupants due to such cold start, a remote start device capable of starting the vehicle even in a house far from the vehicle has been proposed. The use of a remote start device allows the engine to warm up before the occupant reaches the car, but it is not recommended because warming up more than 5 minutes is undesirable, in order to reduce energy consumption and prevent environmental pollution.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems according to the prior art, and an object thereof is to provide a preheater capable of quickly removing frost that has condensed on the glass of a vehicle at the time of cold start of a vehicle.

Another object of the present invention is to provide a preheater capable of increasing the heat capacity as needed.

In order to achieve the above object, the preheater for a vehicle according to the present invention includes a battery for transferring power to each component of a vehicle after accumulating electricity through a generator of the vehicle, a blower for transferring air, and air to the interior of the vehicle. In an automotive air conditioning system including an air duct guiding to a coolant, a coolant for maintaining an engine temperature at a specific temperature, and a radiator for transmitting heat of the coolant described above to the outside, the coolant is filled inside, and a part of the thermal conductivity Cooling water pipe formed of a high material; A radiator having a coolant pipe insertion hole into which a portion formed of a material having high thermal conductivity of the coolant pipe is inserted is formed in a curved zigzag shape, and having a heater insertion hole formed to the coolant pipe inserted into the coolant pipe insertion hole described above; It is characterized in that it comprises a heater which is inserted through the insertion hole for the heater of the above-mentioned radiator and in contact with the above-mentioned coolant pipe, and receives power from the above-mentioned battery and simultaneously heats the above-mentioned radiator and the above-mentioned coolant pipe.

Here, it is preferable that at least two or more insertion holes of the radiator are formed.

In addition, the above-described heater includes: an iron coupling electrode to which the wires of the above-described battery are connected and two iron connection electrodes are formed; Connected to the yaw-shaped coupling electrode and the above-mentioned yaw-shaped coupling electrode, in which a yaw-type connecting electrode which is coupled to the iron-type connecting electrode of the iron-type coupling electrode described above is formed, It is preferable that it is formed in a U shape as a whole and consists of a heating part which radiates heat by the power supply of a battery.

In addition, the preheater according to the present invention, the temperature measured by the water temperature sensor and the above-described water temperature sensor for measuring the temperature of the coolant filled in the above-mentioned cooling water pipe is installed in a portion of the cooling water pipe, the measured temperature is 80 ℃ or more It is preferable to further include a switch to stop the operation of the heater described above.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, it should be noted that the following examples are only for illustrating the present invention in detail and do not limit the scope of the present invention.

First, a configuration of a preheater according to an embodiment of the present invention will be described with reference to FIG. 1.

1 is a schematic perspective view of a preheater according to an embodiment of the present invention.

As shown in FIG. 1, the preheater according to the present exemplary embodiment includes a battery 100, a radiator 120, a coolant pipe 130, and a heater 150.

The battery 100 stores electricity through a generator installed in the vehicle as the vehicle runs, and supplies power required for each component of the vehicle. Electricity stored in the battery 100 is transferred to the outside through the electrodes 101 and 102.

The radiator 120 exchanges heat with the coolant pipe 130 filled with the coolant, and emits heat from the radiator 120 to the outside through the pleats formed on the outside. In particular, a cooling water pipe insertion hole through which the cooling water pipe 130 is bent and zigzag is formed for efficient heat exchange with the cooling water pipe 130, and the cooling water pipe 130 is radiated along the cooling water pipe insertion hole. It is inserted at 120.

One or more heater insertion holes (not shown) are formed in the radiator 120, and the heater 150 is inserted into the heater insertion holes.

The coolant pipe 130 absorbs heat of the engine while circulating around the engine of the vehicle, and then radiates heat from the radiator 120 to cool down, and then returns to the surrounding of the engine again. The portion of the cooling water pipe 130 inserted into the radiator 120 is preferably made of a material having high thermal conductivity, and particularly preferably made of copper or aluminum.

The water temperature sensor 132 is attached to a predetermined portion of the cooling water pipe 130 before being connected to the radiator 120. The water temperature sensor 132 measures the coolant temperature inside the coolant pipe 130 or the coolant pipe 130 and transmits the coolant temperature to the ECU (Electronic Control Unit (not shown)).

The switch 110 is connected to one electrode 101 of the battery 100, and determines whether to operate the heater 150 by cutting off or supplying power according to the above-described command of the ECU.

The heater 150 is composed of an iron coupling electrode 152, a yaw type coupling electrode 154, a radiator heating unit 156, and a cooling water heating unit 158.

The configuration of the heater 150 will be described with reference to FIGS. 2 and 3.

2 is a perspective view of a heater according to an embodiment of the present invention, Figure 3 is a perspective view for explaining the heating according to an embodiment of the present invention.

The iron coupling electrode 152 is connected to the wire 103 from the electrodes 101 and 102 of the battery 100. In particular, the iron coupling electrode 152 is preferably formed of a material having low thermal conductivity so that heat generated from the heater 150 does not leak to the outside. Two iron connection electrodes (not shown) are formed in the iron coupling electrode.

The yaw type coupling electrode 154 is formed with a yaw type connecting electrode which is coupled to the iron connection electrode of the iron type coupling electrode 102. Since the heaters 150 can be separated / coupled with each other using the iron-type coupling electrode 152 and the yaw-type coupling electrode 154 as described above, the life of the heater 150 expires or is broken. In this case, the heater 150 can be easily replaced.

The heating parts 156 and 158 are coupled to the lower end of the yaw type coupling electrode 154. The heating units 156 and 158 may be formed of a heating wire that generates heat according to the power supply of the battery 100, or may be formed in a “U” shape in the form of a hollow tube in which the heating wire is installed in the inner space. However, it should be noted that the present invention is not limited to this shape, and may be formed in a flask shape or a zigzag shape so as to have a wide contact area for more efficient heat exchange.

The heating unit is divided into the radiator heating unit 156 and the cooling water heating unit 158. The radiator heating unit 156 contacts the inner wall of the radiator 120 to heat the radiator 120, and the cooling water heating unit 158 In contact with the outer circumference of the metal coolant pipe 134 inserted into the radiator 120 to heat the coolant pipe 134.

Hereinafter, the operation of the preheater according to the present embodiment will be described with reference to FIG. 5.

Figure 5 is a perspective view of the inside of the vehicle showing a state in which defrost according to the use of the present invention is removed.

Prior to the description, in this embodiment, the ECU turns on the switch 110 when the temperature detected by the water temperature sensor 132 is less than 80 ° C, and turns off the switch 110 when the temperature is above 80 ° C. It is assumed that the starting of the vehicle is cold starting. It is also assumed that the vehicle is exposed to the outside during the winter season, and the glass is erotic.

First, the vehicle user starts the vehicle using a remote starter or directly using a car key.

Immediately after the vehicle is started, the temperatures of the engine and the coolant are equal to room temperature, so that the temperature detected by the water temperature sensor 132 becomes room temperature.

The ECU turns on the switch 110 based on the temperature information detected by the water temperature sensor 132. As a result, the heater 150 supplied with power from the battery 100 generates heat.

Thereafter, the user manipulates the air conditioning switch 164 to remove the frost generated in the glass 160 of the vehicle so that the air duct discharge port 162 formed toward the vehicle glass 160 is opened.

The heat generated by the heater 150 heats the radiator 120 and the cooling water pipe 134. The radiator 120 heated by the heater 150 emits heat to the outside and radiator 120 to an air duct outlet 162 formed toward the vehicle glass 160 through a blowing fan (not shown). The air warmed by the air is supplied to the vehicle glass 160 to quickly remove the frost formed on the vehicle glass 160.

When the frost is completely removed from the vehicle glass 160, the user manipulates the air conditioning switch 164 to open the air duct outlet 166 formed toward the inside of the vehicle. As a result, the air warmed by the radiator is introduced into the vehicle to maintain the temperature inside the vehicle at an appropriate level or higher.

Then, when the temperature of the coolant filled in the coolant pipe 130 becomes 80 ° C or higher as the engine is preheated, the ECU causes the state of the switch 110 to be turned off according to the temperature information detected by the water temperature sensor 132. .

In accordance with the off operation of the switch 110, the heater 150 is no longer operated, thereby preventing unnecessary waste of power of the battery 100 and preventing breakage of the heater 150, while the frost is completely removed. .

In addition, the preheater according to the present invention may increase the heat capacity if necessary. That is, the heater 150 may be inserted into two or more insertion holes for cold weather or faster preheating.

4 is a schematic perspective view of a preheater according to a modification of the present invention.

As shown in Fig. 4, according to this variant, two heaters 150 are inserted into the radiator 120 and used.

In other words, when the vehicle is exposed to cold weather, the engine exhaust is large, the vehicle interior is large, or the fuel of the vehicle is light, the radiator capacity must be increased, and a lot of heat is used to preheat the engine or warm the room. It is necessary.

In this case, when the two heaters 150 are used as shown in FIG. 4, the engine preheating and radiator heating time may be reduced, thereby enabling faster preheating and radiator heating.

In addition, although two heaters 150 are used in FIG. 4, it should be noted that the present invention is not particularly limited thereto, and three or more heaters 150 may be used as necessary.

The embodiments of the present invention have been described above. However, it is to be noted that the present invention is not limited to the above-described embodiments, and various modifications and changes can be made by those skilled in the art within the spirit and spirit of the claims.

As described above, according to the present invention, it is possible to provide a preheater for automobiles capable of removing the frost attached to the glass of the vehicle in a short time.

In addition, according to the present invention, it is possible to increase the heating capacity if necessary, it is possible to provide a preheater for automobiles that is easy to maintain and repair.
