Description

[0001] DESCRIPTION [0002] Heating system for engine and transmission [

FIELD OF THE INVENTION The present invention relates to engine and transmission heating systems, and more particularly to an automotive engine and transmission heating system using electricity.

Conventionally, in order to solve the cold starting problem of the winter engine (automobile, ship, engine hydraulic system equipment), the engine, the fuel system, the air system and the electric system are separately designed with the heat exchanger and the electrically conductive heat storage material (EHPCM) The heat is stored at a predetermined temperature by releasing the heat stored in the electrically conductive storage material when the temperature of the cold starting system is lowered in the cold start system, and when the electrically conductive heat storage material is insufficient for the warming operation, It is for prevention of cold start through heat of heat storage material and heat storage.

1 is a view showing a configuration of a conventional hybrid serial-parallel type engine cold start preventing device. As shown in Fig. 1, exhaust heat and engine coolant heat storage heat exchange using the heat exchanger 18 using the electrically conductive heat storage material 7 are used to heat engine heat and exhaust gas in an automobile, a ship, or an engine- And the heat exchanger 18 is designed so that the heat exchange plates 3 having a staggered angle of inclination of 120 degrees of the internal angle are equally arranged at the center of the area obtained by bisecting the vertical direction of the path through which the air flows, (7) a heat storage tank filled with a conductive hydrogel-converted latent heat storage material is provided on a heat exchange surface on which the hot plate 3 having a staggered inclination angle is contacted.

The material of the heat exchanger 18 is SUS 316 * 0.6T, which is air-tightly assembled by a brazing method, and the photocatalytic coating area 19, which is the surface of the channel through which the exhaust gas passes, is anatase titanium dioxide coating (386 nm) emitted from the UV lamp (5) installed on the straight surface of the heat exchange tube facing the heat exchange plate, the air supply path decomposes and sterilizes contaminants contained in the outside air, The exhaust gas decomposes and discharges the combustion waste gas, thereby having the effect of simultaneously cleaning the feed air and the exhaust air.

The heat exchange characteristics of the heat exchanger 18 are such that the gas that has been moved to each class and exhaust pipe enters the heat exchanger and flows through the heat exchanger 3 having a staggered angle of incidence The streamline that goes straight in line with the direction of the gas going forward and the streamline that goes straight ahead plays the role of going forward in the main stream and the streamline which is compressed against the slope angle is dispersed to small eddy at the peak of the slope angle, Repeatedly breaking down into smaller vortices, generating numerous small vortices (eddy), attracting heat and matter from the surroundings to disperse and maximize the irreversible phenomenon through the heat exchange plate. The heat radiating pipe of the heat exchanger 18 is divided into a heat exchange heat pipe 21 for circulating engine cooling water, a fuel circulation heat pipe 2 and an engine combustion air heating heat pipe 1.

The engine cooling water heat storage heat exchange circulation of the heat exchanger 18 is divided into the winter season and the always summer season in the auto valve 143 and is always performed in the winter season by the auto valve 143 via the heat radiation pipe 21 7) circulates the heat to the heat core after heat is absorbed and stored from the cooling water absorbing the high temperature of the engine. When the temperature of the heat storage tank is higher than the set temperature by the sensor, or in the case of the summer, it is circulated directly from the auto valve 143 to the heat core.

The fuel heat exchange circulation of the heat exchanger 18 is divided by the automatic valve 142 into the winter season and the summer season and the summer season when the cold start is carried out at all times by the automatic valve 142 via the heat radiation pipe 2, The fuel is heated or vaporized by the heat of the ash 7 and supplied to the engine.

Heat exchange heating of the engine combustion air of the heat exchanger 18 is dividedly performed in the automatic valve 141 during the winter season and during the cold start in the winter season and is always transmitted from the auto valve 141 via the heat radiating pipe 1 The external cold combustion air is heated to a certain temperature and supplied to the turbocharger, compressed and then supplied to the engine.

However, as described above, the structure of the conventional cold start preventing apparatus is very complicated, and the driving system (engine and transmission) is quickly switched to the optimum performance by a method of supplying heat again to the simultaneous cold engine using a heat exchanger Not only the heating time is very slow, but also there is a fatal problem that if the fluid to circulate the heat is frozen in a complicated configuration, the system can become useless.

In addition, recently, a device that maintains a constant temperature by using an engine block heating apparatus using electricity used in cold regions at present is commercialized and sold, and it is easy to start the engine and the transmission while the cooling water and the lubricant are preheated And allows the given performance to be immediately available. Recently, conventional heating systems are systems for maintaining the engine block and the transmission at a constant temperature that is easy to start or using the supplied 110 volt power source as a power source, or for preventing the freezing. These devices have limitations in that they are useless in places where there is no external power supply.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. 2 is a circuit diagram of an engine and a transmission heating system of an automobile using electricity according to an embodiment of the present invention. As shown in FIG. 2, the automotive engine and transmission heating system according to the embodiment of the present invention includes a temperature sensor 100 mounted on the outside of the vehicle engine and the transmission to measure the temperature of the engine and the transmission gear; An engine and a transmission heater mounted on the outside of the automobile engine and the transmission to heat the temperature of the engine and the transmission; A battery 300 connected to the heater 200 for supplying power to the vehicle; And a battery 300 voltmeter 400 for measuring the remaining voltage of the battery 300.

As described above, the present invention proposes a system for shortening the heating time of an engine and a transmission of an automobile, wherein the time required for the engine and the transmission to be heated to an appropriate temperature after the start of the vehicle, The present invention proposes an automobile engine and transmission heating system capable of shortening the heating time of the engine high-speed transmission by using power not used after startup such as the battery 300 for power supply as well as improving fuel efficiency.

The automobile to which the engine and transmission heating system of the present invention is applied includes gasoline, diesel, gas-fueled automobiles and electric automobiles, as well as diesel engines, generators, air compressors, agricultural equipment, water pumps, A mechanical device using a fluid such as a hydraulic oil, an intake manifold, a battery 300, an engine block, a snow remover, a chain saw, a snowmobile, a small engine, a hydraulic system, a pipe, Of course.

Here, the temperature sensor 100 is a sensor for measuring the temperature of an engine and a transmission (Transmission). When the engine and the transmission fall below a specific temperature in the winter, the drive system (engine and transmission) The performance of the engine can not be exerted. When the engine and the transmission are heated through the heater, there is a risk of explosion if the engine is heated too much. Therefore, the drive system of the vehicle is operated stably within an appropriate range, And the temperature of the engine and the transmission needs to be monitored from time to time.

The engine and transmission heater 200 are preferably installed on the outside to use a block type, a magnet type, a dip stick type, and a pad type heater 200 as a heating device for heating the engine and the transmission. This is because it is easy to mount on an engine and a transmission, is compact and does not take up a lot of installation space, and can be easily attached and detached so that it can be easily repaired and replaced as needed.

The battery 300 for power supply is a device for storing the electricity generated by the alternator and for supplying electricity to the electric system of the vehicle. The automobile battery 300 includes a lead acid battery and an MF And a battery 300. In an embodiment of the present invention, both the lead acid battery and the MF battery 300 are usable.

MF battery 300 uses a gel-like material instead of diluted sulfuric acid, and calcium component is added to the alloy component of the internal electrode, so that the battery 300 liquid does not evaporate. Therefore, there is no need to replenish the distilled water, and it has the advantage that the lifetime is much longer because it does not touch like the lead acid battery.

In the embodiment of the present invention, when the temperature of the engine and the transmission is lowered through the temperature sensor 100 during the winter season by supplying power to the heater 200 directly connected to the battery 300, And then the heater 200 is automatically operated to heat the engine and the transmission to prepare the driving system so that the optimum performance can be exhibited in a short period of time.

Conventionally, a method of using an external power source or a method of heating by using a heat exchanger having a complicated structure inside the vehicle is used as described above. However, as in the embodiment of the present invention, 300) power is used, it is possible to shorten the heating time of the engine and the transmission, and to provide a highly user-friendly system that does not require installation and pre-work for using an external power source.

 In the embodiment of the present invention, since the temperature of the engine and the transmission are constantly monitored through the temperature sensor 100, when the temperature of the engine and the transmission is lowered below a predetermined temperature, the heater 200 is operated through the battery 300, When the temperature rises above a certain temperature, the power supply to the heater 200 is automatically shut off, and the system can be quickly changed to an optimal performance in a suitable range.

In addition, as shown in FIG. 2, since the electric power is supplied to the engine and the transmission heating system using the electric power by the heater 200 through the battery 300 according to the embodiment of the present invention, A battery 300 voltage meter 400 for measuring a residual voltage is installed in the battery 300 to prevent a case where all the voltages are discharged.

Battery 300 If the voltmeter 400 is installed and the battery 300 falls below a certain residual voltage capable of supplying sufficient power for starting the vehicle, The main switch 350 or the voltage switch 450, so that the discharge of the battery 300 can be prevented in advance. In addition, even when the user of the vehicle accidentally leaves the vehicle with the electric device such as a light turned on, the residual voltage of the battery 300 is checked through the voltmeter 400 of the battery 300 to cut off the power, Of course.

3 is a circuit diagram of an engine and a transmission heating system of an automobile using electricity according to an embodiment of the present invention. 3, the automotive engine and transmission heating system according to the embodiment of the present invention includes a temperature sensor 100 mounted on the outside of the automobile engine and the transmission to measure the temperature of the engine and the transmission. An engine and a transmission heater mounted on the outside of the automobile engine and the transmission to heat the temperature of the engine and the transmission; A battery 300 connected to the heater 200 for supplying power to the vehicle; An alternator (500) for applying power to the heater (200) after starting the automobile; And a battery 300 voltmeter 400 for measuring the remaining voltage of the battery 300.

3 differs from the embodiment of FIG. 2 in that an apparatus for supplying power to the heater 200 through the alternator 500 after startup is illustrated, and the other configuration is the same as that of the embodiment of FIG. 2, Description thereof will be omitted.

Here, the alternator 500 refers to an alternator, which is used in a vehicle, and refers to a generator capable of charging an accumulator battery even at a relatively low engine speed by generating alternating current electricity.

The alternator 500 has no radio interference, is excellent in durability, and is strong in generating power even at low-speed rotation. A three-phase alternating current is generated in the fixed coil by rotating the magnetic pole excited by the battery 300, and the alternating current is rectified by a diode and drawn out by a direct current.

An alternating-current power generation charger or alternator 500, also referred to as a generator, is an electrical device that converts mechanical energy into electrical energy. The automobile charges the battery 300 while driving engine power to the belt. The alternating current type is also capable of charging even when the battery 300 is idling, and the alternating current generated by the alternator 500 is rectified by the direct current used in the automobile in the diode connected to the inside.

The use of the alternator 500 in the embodiment of the present invention allows the electric power to be continuously supplied to the heater 200 after the automobile starts to supply power to the battery 300 and is generated in the alternator 500 as an alternator The power of the battery 300 can be strategically provided by supplying power to the heater 200 by using a power source, and by using an optimal power source by selectively changing the power supply line as needed, It is because we can plan.

As described above, according to the present invention, by applying power to the heater 200 through the power supply battery 300 or the alternator 500, the cold winter engine and the transmission are heated to assure start-up and instant lubrication, the present invention provides a heating system capable of preventing engine wear due to a cold start, as well as providing a car engine and a transmission heating system which are quick and easy to install and low in cost. In addition, it is possible to shorten the heating time of the engine and the transmission by using unused power after starting.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
