Description

AIR CONDITIONING AND MOTOR COOLING

FOR VEHICLES BY EXHAUST GAS

The present invention relates to a device for air conditioning and cooling of motor vehicles driven by the internal combustion engine. This discovery offers an alternative solution without any consumption of engine power. The invention can u. a. In the following areas of the automotive industry are used: cars, trucks, special vehicles (goods and passenger transport), agricultural machinery, construction machinery and other means of transport, which are powered by internal combustion engines.

The air conditioners currently available on the market are powered by the vehicle engine and consume some of the engine's power, which means that fuel consumption is increased by about one liter. The vehicle engine starts the compressor, which compresses the refrigerant to about 15 bar. The compressed refrigerant is cooled in a condenser, whereupon it vaporizes and absorbs the heat from the ambient air of the air conditioner. The refrigerant contains environmentally harmful chemicals.

The vehicle engine currently sold on the market is cooled using water or a special liquid; this liquid is cooled in a cooler by means of a fan driven by the motor. This consumes a part of the engine power, which leads to its reduction and to increase the fuel consumption.

To avoid the above-mentioned technical and financial disadvantages, a sucker, which works by the residual heat of the leaked engine exhaust gases used. The sucked exhaust air flows through a heat exchanger, in which the air required for the air conditioning is cooled. The sucker also absorbs the air through a cooling system that dissipates the heat of the cooling water to the engine cooling system.

Apply the present invention to all types of internal combustion engines (both foreign and compression-ignition engines) for motor vehicle drive.

The invention consists of two interconnected components.

a. AIR CONDITIONING

This ensures the air conditioning of the vehicle throughout the year (regardless of the season).

b. COOLING SYSTEM

This ensures the engine cooling of the vehicle. Both systems operate by means of a vacuum cleaner (A), (Fig la), which works by means of the residual heat of the leaked engine exhaust gases. a. AIR CONDITIONING

The air conditioner consists of a vacuum cleaner with multiple pipes (A), a heat exchanger (B), several air filters and electronic throttle valves (Fig la):

- fi, f ^* 2, f ₃ - filter for filtering the atmospheric air.

- ei, e ₆ - Adjustable electronic throttles that regulate the flow of air circulating through the pipes. The electronic throttles "e _l5 e ₆ " are controlled by an on-board computer or by a separate (or integrated) electronic control unit.The required temperature is set in the passenger compartment.The on-board computer controls the adjustable electronic throttles and thus regulates the air flow in the heat exchanger for cooling The electronic throttle valves work in a similar way to the carburettor throttle, which can also be manually controlled using levers and cables.

The multi-tube vacuum cleaner (A), (la), absorbs the atmospheric air through the filter (ft), the electronic throttle (e ₂ ), the heat exchanger (B), the pipeline (2) and the electronic throttle ( The air enters the sucker (A) and reaches through the pipe (3) the tailpipe of the exhaust (T), mixes with the exhaust gas and is released into the atmosphere.

In the heat exchanger this air flow cools the air from the second circuit (4) in concentric tubes (FIG. This draft flows through the fan (E) in the vehicle interior. The air circulation system (4) consists of the fan (E), which absorbs the atmospheric air through the filter (f ₂ ), and the electronic throttle (e ₃ ) and the heat exchanger (B). This air circulation system (4) is essential as the air must be cleansed of contaminants, pollen and other allergenic substances and a certain humidity must be ensured.

The vacuum cleaner with multiple tubes (A) is shown in simplified form in FIG. 2. This consists of a housing (1) in the form of a cuboid. The housing (1) is composed of two basins, (2) and (3), which are interconnected by some metal tubes (4) together. In the housing (1) flow through the inlet (5) engine exhaust gases. The exhaust gases surround and heat the tubes (4), flow through the inlet (6) into the outlet pipe (1), (FIG. 1 a), into the exhaust (T) and pass over the pipe (10), (FIG ), into the atmosphere. The air entering from the heat exchanger (B) flows into the tank (2) through the inlet (7), traverses the pipes (4), heats up and rises in the tank (3). From there, the air passes through the inlet (8) and through the pipe (3), (Fig la), in the tailpipe of the exhaust (T).

The multi-tube vacuum cleaner (A) works according to the following principle: in a metal tube, which is positioned upright or inclined and heated by any means, the air inside the tube heats up and circulates from bottom to top with one Speed that is directly proportional to the heating temperature. To ensure the required air cooling, according to the above principle, the multi-tube vacuum cleaner, whose performance is increased by the increasing number of tubes, was built (the tubes may be arranged in one or more rows as needed). The exhaust gas temperature is above 600 ° C; This state allows a sufficiently high air mass throughput for optimal operation of the nipple.

The tailpipe of the exhaust (T), (Fig. 1b), has a special construction. This consists of the tube itself (9), which directs the exhaust gases from the exhaust to the outside and is surrounded by another tube (10); in the latter (10) passes through the inlet (1 1) heated air coming from the sucker. The exhaust gases circulating in the pipe (9) escape at a rather high speed, sucking in the heated air between the two pipes, mixing with it and passing out into the atmosphere. The exhaust gases thereby support the improved operation of the nipple. The air mass flow, which flows out of the nipple, is sufficiently high, so that the mixture with the exhaust gases creates a breathable mixture.

The specific exhaust gas weight is higher than the air weight. By mixing the exhaust gases with the heated air creates a mixture whose specific weight comes close to the weight of the air. This warm mixture, in turn, mixes with the ambient air and rises faster into the atmosphere, resulting in better air quality on the ground than the current one. The present invention thus contributes to environmental improvement.

The heat exchanger is shown in simplified form in FIG. 3. This consists of two basins, (1) and (2), which are interconnected by means of a system of concentric tubes (3) together. The pipe system (3) consists of three concentric pipes, (4), (5) and (6), (Figure 3 a). The basin (1) is divided into three separate areas, (7), (8) and (9). The sections (7) and (8), (Fig. 3a), communicate with each other. The basin (2) is divided into three separate areas, (10), (11) and (12), (Fig. 3a). The sections (10) and (11) are interconnected. The two basins (1) and (2) are united as follows by means of a system of concentric tubes, (4), (5) and (6), (Fig. 3a):

- The section (11) is through the tube (5) in connection with the section (7).

- The section (10) is through the tube (4) in connection with the section (8).

- The section (12) is through the tube (6) in connection with the section (9).

The group of concentric tubes, (4), (5) and (6) are arranged in two rows (Fig. 3 c). The number of tubes and the number of rows are determined depending on the required amount of air.

The air absorbed by the sucker (A) through the filter (fi), (Fig. 3a), the electronic throttle (e ₂ ) and the inlet (13), enters the section (11), from where the air flow over the tubes (5) merges into the section (7). Since the portion (11) is connected to the portion (10), the air from the portion (11) in the section (10) over. About the space between the tubes (4) and (6) then finally enters the section (8). The section (8) in turn is in connection with the Section (7), so that the air flows through the inlet (14) and via the tube (2), (Fig la), in the sucker (A) penetrates the suction pipes and passes through the pipe (3) the end of the Exhaust (T) reached. The section (9), (Fig. 3a) is connected to the section (12) via the space between the tubes (5) and (6). The air sucked in via the blower (E), (FIG. 1 a) is cooled in the heat exchanger (B).

The air sucked in via the blower (E) passes through the filter (f ₂ ), the electronic throttle valve (e ₃ ), (FIG. _{1 a} ), and passes through the inlet (15), (FIG. 3 a) into the section (FIG. 9). From there it penetrates into the section (12) via the space between the pipes (5) and (6) and through the inlet (16) reaches the blower (E) and flows into the vehicle interior. A connection exists between the tubes (5) and (6), as well as the air taken in via the teat; this takes over part of the heat of the air flow which circulates between the pipes (5) and (6), whereby an air cooling is generated. The tubes (3) and (4), (Fig. 3a, Fig. 3b), pass through some metal plates (17).

The heat exchanger is mounted in front of the engine so that the air resulting from the movement of the vehicle cools the plates (17) and the tubes (4), thereby increasing the amount of heat supplied via the circuit (4). By means of the electronic throttle valves, the air mass flow rate circulating through the two circuits can be controlled. Through the outlet of the blower (E), the desired temperature of the cooled air is achieved.

The tubes (4), (5) and (6) and the plates (17) can be made of aluminum and the plastic pelvis. Tubes and plates can also be made of brass or copper, but are heavier and more expensive.

The Klimatisierun ^g in winter: In the winter, the electronic throttle valve (e _2), (Fig la.), And the electronic throttle valve closed (e ₄₎ is opened. In the heat exchanger (B), a warm air flow, which heats the air circulating in the pipe (4), spreads via the pipe (5). By means of the blower (E) this then enters the vehicle interior. By mixing the cold with the warm air, the desired temperature can be set inside the vehicle.

b. ENGINE COOLING

The engine cooling system consists of the vacuum cleaner with the multiple pipes (A) and the radiator (C), (Fig la and Fig. 4):

- The circuit (6), through which the sucker (A) through the filter (f ₃ ), the electronic throttle (e ₅ ), the radiator (C) and the electronic throttle (e ₆ ) absorbs the atmospheric air.

- The warm water circuit from the engine (M) through which the hot water enters the cooler (C) by means of a pump. In the cooler, the water is cooled within a system of concentric tubes by means of the air absorbed by the sucker.

- The cold water circuit (8) through which the cooled water reaches the engine (M). Through the opening of the electronic throttle valves (e ₅ ) and (e ₆ ), (Fig la), air flows through the tubes (4) and (5), (Fig. 4b), the radiator (C) and thereby cools the Water, which flows through the tubes (6), (Fig. 4b), the radiator (C).

To cool the engine coolant under any operating condition, a sufficient air mass flow rate is ensured by means of the vacuum cleaner (A). The sucker (A) may be constructed so that the required amount of air for cooling the coolant is provided by the increasing number of tubes (4), (Fig. 2). The radiator (C) cools the engine coolant above the air absorbed by the nipple and over the vehicle motion resulting air which cools the plates (17) and the tubes (4), (Figure 4b).

The sucker ensures sufficient air mass throughput for water cooling, eliminating the need for a radiator fan and increasing the vehicle's engine output.

The cooler is shown in simplified form in FIG. This consists of two basins, (1) and (2), which are interconnected by the system of concentric tubes (3).

- The pipe system (3) consists of the three concentric pipes (4), (5) and (6).

- The basin (1) is divided into the three sections (7), (8) and (9). The section (7) is connected to the section (8).

- The pelvis (2) is divided into the three sections (10), (1 1) and (12). The sections (10) and (11) are interconnected.

- The section (11) is connected to the section (7) by means of some tubes (5).

- The section (10) is connected to the section (8) by means of the tubes (4).

- The section (12) is connected to the section (9) by means of the tubes (6).

The group of concentric tubes, (4), (5) and (6) are arranged in two rows. The number of tubes and the number of rows are determined depending on the required amount of air.

By the vacuum cleaner (A) absorbed air passes from the atmosphere through a filter (f _3), the electronic throttle valve (e _5), the inlet (13) in the portion (1 1); from there it passes through the tubes (5) in the section (7). Since the portion (11) is connected to the adjacent (10), the air flow flows from the portion (11) in the section (10). From there it passes via the tubes (4) into the section (8), which is combined with the section (7). As a result, the air flows through the inlet (14) via the pipe (6), (Fig. 1), to the sucker (A), passes through the pipes and via the pipe (3) this reaches the tailpipe of the exhaust (T). The portion (9) is connected to the portion (12) over the gap of the tubes (5) and (6).

The hot water coming from the engine passes through the inlet (15) into the section (9) and enters the section (12) through the interspace of the tubes (5) and (6), and returns to the engine through the inlet (16) , The tubes (5) and (6) are in communication with the absorbed air from the sucker, which heat the through the tubes (6) receives circulating water in it. The water is cooled down to a temperature of about 30 ° C, thereby cooling the engine.

The tubes (4) pass through metal plates (17).

The radiator is mounted in front of the engine so that the air resulting from the movement of the vehicle cools the plates (17) and the tubes (4), thereby increasing the amount of heat absorbed by the water. In addition, by means of the electronic throttle valves (e ₅ ) and (e ₆ ), the volume of air for water cooling can be controlled.

The tubes are arranged in two rows. The number of tubes and the number of rows are determined depending on the required amount of air for water cooling under any operating condition.

This system ensures a good engine cooling at all times and can be a positive effect, a waiver of the fan used to date. Further advantages can u. a. be: an increase in engine power and a reduction in vibration and engine noise.

The present invention consists of simply assembled components of common materials:

- The teat with multiple tubes, (Fig. 2), is a simple preparation. This consists of a housing (1), for example of a welded steel plate, which is resistant to temperatures of over 600 ° C. The tubes (4) are also made of steel, so as to be able to withstand the high temperatures.

- The concentric tube cooler (4) consists of two basins, (1) and (2), the tubes (4), (5) and (6) and the plates (17). The basins can be made of plastic or aluminum sheet, copper or brass. The tubes (4), (5) and (6) are commercially available tubes made of aluminum, brass or copper. The plates (17) may be either aluminum sheet, brass or copper.

- The (commercially available) electronic throttle valves work like the valves of carburetor engines.

In addition, a simple underfloor heating can be attached to the vehicle, as it can form a layer of snow and ice in cold winter months. This slows down the movement of the vehicle and leads to an increase in fuel consumption. Through a simple construction using some tubes that attach to the teat, above the tires, then along the door sills to the exhaust, the floor of the vehicle heats up by the heat generated thereby, so that no more ice can form.

The present invention has the following advantages over the current technical standard on the market:

- It ensures an optimal climate in summer and winter months, without any engine power is consumed. - It reduces fuel consumption by about one liter.

- It uses waste heat gas, which currently escapes into the atmosphere.

- It contains no moving parts.

- It does not use environmentally harmful chemicals.

- From the tailpipe of the exhaust escapes a breathable gas mixture.

- The mixing of the exhaust gases with the heated air contributes to the reduction of the specific exhaust weight, whose weight then comes close to that of the air weight. This escaping mixture in turn mixes with the ambient air and rises faster into the atmosphere, so on the ground better air quality than the current is achieved.

- Optimum engine cooling, without any consumption of engine power, is made possible.

- The engine cooling is obtained by using the exhaust heat.

- The absence of the previously used motor fan leads to an increase of the engine power and to a reduction of the vibrations as well as the engine noises.

- In the calculation of the efficiency, ie the ratio of the useful heat to the total heat from the fuel combustion, an improvement in engine efficiency is determined because part of the heat is used for engine cooling.

- Also required for the combustion cylinder air can be cooled.

- By cooling the supply air of the engine increases the coefficient for filling the cylinder and an increase in engine power is brought about.

- The exhaust gas temperature is reduced by more than 50%, the efficiency of the catalyst improves and its life is extended.

- The resulting from the system, offering underfloor heating, which generates heat without additional costs, has further advantages: no further ice formation under the vehicle; a reduction in fuel consumption; Providing corrosion protection for sheet metal and welds; no additional consumption of engine power; and finally a dry and corrosion protected vehicle, which pleases every vehicle owner.

As can be seen from the advantages listed above, the present invention offers a new solution which can be used in the automotive industry.
