Günümüzde kullamlan motor sogutma sistemleri fan - fan motoru, grubu, davlumbaz, stator, fan çerçevesi ve radyatör - kondenser ~ sogutucu grubundan olusmaktadir. Motor içinde dolasarak motorun sicakligi ile isinan sicak su, radyatör grubunun içinden geçmektedir. Su sicakligi belirli bir degere ulastigin da sicaklik ölçer tarafindan alinan sinyal ile fan motoru devreye sokulmakta ve fan pervanesi (I) dönerek radyatör grubu üzerinden hava emerek (veya basarak) sicak suyun isisinin havaya geçmesi saglanmakta ve su sicakligi düsürülmeye baslanmaktadir. Su sicakligi belirlenen degere kadar azaldiginda sicaklik ölçer 6876.1 19 tarafindan alinan sinyal ile fan ve fan pervanesi devre disi birakilarak asiri sogutma önlenmektedir. Bulus konusu bir motor sogutma sisteminde (1), motorda (2) yer alan egzoz çikis manifoldundan çikan sicak egzoz gazlari, aracin turbo ünitesinden (3) geçerek basinçli hava çikisina (6) gönderilmektedir. Ayni zamanda turbo ünitesi (3) tarafindan temiz hava girisinden (4) çekilen taze hava basinçlandirilarak basinçli hava çikisindan (6) sogutma ünitesine (7) gönderilmekte ve sogutulmaktadir. Sogutma ünitesinden (7) çikan basinçlandirilmis ve sogutulmus hava, tekrar motora (2) gönderilmekte ve böylece motor (2) silindirine daha fazla hava kütlesi iletilmis olmaktadir. Bu durum ise motorun (2) verimi ve gücünü artirmaktadir. bir motor sogutma sistemi (1) çalisir durumda iken sürücü ayagini gazdan çektiginde motora (2) hava girisi azaldigi için olusan karsi basincin turbo ünitesi (3) pervanesini yavaslatip verimi düsürmemesi için bu anda bir by-pass vanasi ile sicak egzoz gazlarinin bir kismi by-pass edilerek turbo ünitesine (3) gönderilmeden dogrudan egzoz çikisina (5) gönderilmekte ve dis ortama aktarilmaktadir. Ayrica motor (2) devri belli bir degerin üzerinde oldugunda, turbo ünitesi (3) devre disi birakilarak motorun (2) kontrolsüz güç artisi önlenmektedir. Bu amaç ile bir motor sogutma sisteminde (1) turbo ünitesi (3) tercihen hareketli kanatçiklardan olusmakta ve egzoz basinci - sicak gaz debisine göre bu kanatçiklar hareket ederek kontrollü bir basinçli hava üretimi elde edilmektedir. Bunun nedeni turbo ünitesinin (3) motorun (2) ihtiyacindan daha fazla basinçli hava üretme kapasitesi oldugundandir. Ancak düsük devirlerde basinç ihtiyacinin karsilanmasi için turbo ünitesinin (3) mevcut kapasitesi asagi çekilemediginden orta ve yüksek devirler için ihtiyaç fazlasi basinçli havanin kullanilabildigi bir motor sogutma sistemi (1) olusturulmaktadir. Böylece turbo ünitesi (3) yüksek devirlerde devre disi birakilmak zorunda kalinmamakta ve üretilen ihtiyaç fazlasi basinçli hava bir motor sogutma sistemi (1) tarafindan kullanilmaktadir. Bununla birlikte sürücü ayagini gazdan çektiginden karsi basinç nedeni ile turbo ünitesi (3) pervanesinin yavaslayip verimi azaltmamasi için ihtiyaç fazlasi egzoz gazlarinin by-pass edilerek dogrudan egzoz çikisina (5) 6876.119 gönderilmesine gerek kalmamaktadir. Bu sekilde ayrica sürücünün ayagini gaz pedalindan çektigi ancak olusmus olan ihtiyaç fazlasi basinçli hava motorun (2) isinmasina tekabül eden çalisma zamaninda kullanilabilmektedir. Bulus konusu bir motor sogutma sisteminde (1), fan - fan motoru yer almamaktadir. Fan motorunun bulundugu yere hava yükseltici (9) yerlestirilmekte ve sogutma islemi bu hava yükseltici (9) araciligiyla gerçeklestirilmektedir. Sogutulmus ve basinçlandirilmis hava by-pass çikisindan (8) hava yükselticiye (9) gönderilmektedir. Buradan beslenen hava, hava yükseltici (9) tarafindan radyatöre (10) dogru üIlenmekte veya emilmektedir. Bu sekilde radyatör (10) içindeki akiskanlar tercih edilen degerlere kadar sogutulmus olur. Sogutma ünitesi (7) tarafindan sogutulmus ve basinçlandirilmis havanin tercihen %95°lik kismi ile motorun (2) beslenmesi saglanmaktadir. Orta ve yüksek devirler de motora (2) giden hava miktarinda herhangi bir azalma gerçeklesmemektedir. Fazla üretilen havanin tamami ise hava yükselticiyi (9) tahrik etmektedir. Bu sekilde ayni sogutma isi yapilmakla birlikte, radyatör fani ve pervanesi, kablolari, rezistör ve kontrol sistemi gibi önceki teknikte yer alan sogutma ekipmanlari kullanilmamaktadir. Bir motor sogutma sistemi (1) ile daha hafif ve daha ucuz bir sogutma islemi elde edilmis olmakla birlikte, radyatörün (10) sogutulmasi için gerekli olan enerji artik egzoz gazlari isisindan karsilanarak yüksek güçlü bir elektrik motoru kullanimi ortadan kaldirilmis olmaktadir. Bu sekilde yakit tasarrufu elde edilmekte ve motor emisyon degerleri azaltilmaktadir. Ayrica elektrik üretimi için kullanilan alternatör veya sarj dinamosu gücü ihtiyaci da azaldigindan tasarruf daha fazla olmaktadir. TRDESCRIPTION AN ENGINE COOLING SYSTEM Technical Field This invention is an engine that is operated by recovering the engine's residual heat. Previous Technique In automobiles powered by an internal combustion engine, the radiator is connected to the cylinder where the coolant is pumped and the cooling channels that circulate throughout the engine block. This fluid is usually water mixed with ethylene glycol (antifreeze). The fluid moves from the radiator to the engine in a closed system, during this movement it carries the heat on the engine parts to the radiator. The radiator is generally mounted on the grilled section at the front of the vehicle. Cold air passes through these grilles and cools the radiator. Here, cold air is sometimes due to the movement of the vehicle, but in some cases it is provided by the cooling fan located in front of the radiator. This cooling fan is expensive and heavy. A large amount of electrical energy is required to operate it. Since the cooling fan system requires complex and moving parts driven by electric motors, the risk of failure is high and the maintenance cost is high. In addition, the fan system has a disturbing noise level, and expensive insulation materials are needed to eliminate this noise. It requires additional space for its placement. In the Russian patent document numbered RU, which is in the state of the art, it is mentioned to increase the systems that regulate the temperature of the cooling medium (water, oil, etc.) of automatic regulators and thermal engines. Thermal engines consist of a cooling medium, a booster and a three-way by-pass valve. The microprocessor combines the thermal engine temperature regulators 6876.119. These regulators have external cooling air, thermal engine power sensor and a flow sensor of the cooling medium of the heat pump passing through the thermal engine. Four sensors are connected to a microprocessor. In the microprocessor, there is a program that performs four operations in a manner similar to a stationary temperature regulation, in accordance with the mathematical model of the cooling system of the thermal engine. Thus, automatic variations of the transition constant of the thermal regulator use the output signals for these four sensors. With the invention, fuel consumption is reduced and the efficiency of the thermal engine is increased. In the international patent document numbered WO9717536(A1) in the state of the art, a device is mentioned that controls the cooling and heating of fluids in vehicles. Compressed air is transmitted to the spiral pipe or air riser. Thus, the compressed air expands and cools rapidly. Cooling occurs at the first outlet of the spiral pipe (14) and at the hotter second outlet (18). The first fuel inlet port (20) of the first heat exchanger (16) is located close to the first outlet (16). Thus, the fuel flow passing through the inlet port (20) is cooled by thermal contact with the first outlet (16) of the spiral pipe (14). The cooled fuel outlet port (22) of the heat exchanger (16) is located close to the first outlet. Therefore, the cooled fuel leaves the heat exchanger (16) for transmission to an engine. A valve and two downstream passages (28, 30) are located with the upstream passage (26). Thus, fuel is delivered to the first fuel inlet port (20) and one of the two downstream passage ports (28,30). Brief Description of the Invention The purpose of this invention is to realize an engine cooling system that can be operated without using an electric fan motor, fan part, engine connection equipment, electrical cable, relay and support parts. 6876.119 Another purpose of this invention is to realize an engine cooling system that provides fuel saving since the necessary air flow is provided by waste heat. Another purpose of this invention is to realize an engine cooling system that does not produce fan noise since it does not have a fan and also does not require maintenance since it does not contain any moving parts. Detailed Description of the Invention An engine cooling system implemented to achieve the purpose of this invention is shown in the attached figures and these figures are; Figure 1. Schematic view of an engine cooling system. Figure 2. Perspective view of a radiator group containing an engine cooling system. Figure 3. Side view of a radiator group containing an engine cooling system. The parts in the figures are numbered one by one and the correspondences of these numbers are given below. An engine cooling system Turbo unit Fresh air inlet Exhaust outlet Compressed air outlet Cooling unit By-pass outlet 9989`??pr Air riser . Radiator 6876.119 An engine cooling system (1) which is operated by recovering the engine's residual heat, and which can be used without the use of an electric fan motor, a fan part, engine connection equipment, electrical cables, relays and support parts, in its most basic form, at least one internal combustion engine (2), - at least one turbo unit (3) which pressurizes the exhaust gases coming out of the engine (2), - at least one fresh air inlet (4) which allows air to be taken from the outside environment in the turbo unit (3), - at least one exhaust outlet (5) which allows the exhaust gases coming from the engine (2) and entering the turbo unit (3) to be transferred to the outside environment, - at least one pressurized air outlet (6) through which the air pressurized in the turbo unit (3) is discharged, - at least one cooling system through which the air coming from the pressurized air outlet (6) is cooled. unit (7), - at least one by-pass outlet (8) that separates some of the air cooled in the cooling unit (7) and moving towards the engine (2), - at least one air riser (9) into which the air coming from the by-pass outlet (8) enters and where high cooling is performed, - at least one radiator (10) that cools the hot water circulated inside by means of the air riser (9). The engine cooling systems used today consist of fan - fan motor, group, hood, stator, fan frame and radiator - condenser ~ cooler group. The hot water circulating inside the engine and heated by the temperature of the engine passes through the radiator group. When the water temperature reaches a certain value, the fan motor is activated by the signal received from the temperature gauge and the fan impeller (I) rotates and sucks air through the radiator group (or presses it) to ensure that the heat of the hot water passes into the air and the water temperature is started to be lowered. When the water temperature decreases to the determined value, the fan and the fan impeller are disabled by the signal received by the temperature gauge 6876.1 19, preventing excessive cooling. In an engine cooling system (1) according to the invention, the hot exhaust gases coming out of the exhaust outlet manifold located in the engine (2) are sent to the pressurized air outlet (6) by passing through the turbo unit (3) of the vehicle. At the same time, the fresh air drawn from the fresh air inlet (4) by the turbo unit (3) is pressurized and sent to the cooling unit (7) from the pressurized air outlet (6) and cooled. The pressurized and cooled air coming out of the cooling unit (7) is sent back to the engine (2) and thus more air mass is transmitted to the engine (2) cylinder. This increases the efficiency and power of the engine (2). When an engine cooling system (1) is running and the driver takes his foot off the gas pedal, the air intake to the engine (2) decreases, so that the back pressure created slows down the turbo unit (3) propeller and reduces efficiency. At this time, a part of the hot exhaust gases are bypassed with a by-pass valve and sent directly to the exhaust outlet (5) without being sent to the turbo unit (3) and transferred to the outside environment. In addition, when the engine (2) speed is above a certain value, the turbo unit (3) is disabled, preventing uncontrolled power increase of the engine (2). For this purpose, the turbo unit (3) in an engine cooling system (1) preferably consists of movable fins and these fins move according to the exhaust pressure - hot gas flow rate, thus obtaining controlled pressurized air production. This is because the turbo unit (3) has the capacity to produce more compressed air than the engine (2) needs. However, since the current capacity of the turbo unit (3) cannot be reduced to meet the pressure requirement at low speeds, an engine cooling system (1) is created in which the excess compressed air can be used for medium and high speeds. Thus, the turbo unit (3) does not have to be disabled at high speeds and the excess compressed air produced is used by an engine cooling system (1). However, since the driver takes his foot off the gas pedal, there is no need to send the excess exhaust gases directly to the exhaust outlet (5) 6876.119 in order to prevent the turbo unit (3) propeller from slowing down and reducing efficiency due to the back pressure. In this way, the excess pressurized air that is created when the driver takes his foot off the gas pedal can be used during the working time corresponding to the warming up of the engine (2). In an engine cooling system (1) which is the subject of the invention, there is no fan - fan motor. An air amplifier (9) is placed where the fan motor is located and the cooling process is carried out by means of this air amplifier (9). The cooled and pressurized air is sent to the air amplifier (9) from the by-pass outlet (8). The air fed from here is blown or sucked by the air amplifier (9) towards the radiator (10). In this way, the fluids in the radiator (10) are cooled to the preferred values. The cooling unit (7) preferably feeds the engine (2) with a 95% portion of the cooled and pressurized air. There is no decrease in the amount of air going to the engine (2) at medium and high speeds. All of the excess air produced drives the air amplifier (9). In this way, the same cooling work is done, but cooling equipment such as the radiator fan and propeller, cables, resistor and control system in the previous technique are not used. With an engine cooling system (1), a lighter and cheaper cooling process is achieved, and the energy required for cooling the radiator (10) is now provided by the heat of the exhaust gases, eliminating the use of a high-power electric motor. In this way, fuel savings are achieved and engine emission values are reduced. In addition, the need for alternator or alternator power used for electricity generation is reduced, resulting in greater savings. TR
