• the invention also relates to a cooling method for cooling an oil circuit of an engine by means of a cooling circuit formed by channels in a cooling circuit
• Oil-coolant heat exchanger flowing coolant comprising an engine block and / or a cooler module comprising the steps of directing the coolant through a first section of the cooling circuit that runs through the engine block, passing the coolant through a second section of the
• BESTATIGUNGSKOPIE Cooling circuit which runs through the oil-coolant heat exchanger, and closing the cooling circuit.
• Such cooling devices and methods for cooling an internal combustion engine of a motor vehicle are used today in all motor vehicles. Oil is cooled using a coolant. Different types of cooling devices are distinguished, for example with regard to the coolant.
• a cooling device is the air-oil cooler. This is arranged on the front of the motor vehicle in the air flow generated when driving.
• a disadvantage of this solution is that the coolant used - air - has a relatively small heat transfer coefficient. In order to achieve sufficient oil cooling, a relatively large air-oil cooler is therefore necessary. In addition, the cooling is dependent on the air flow and thus on the driving speed of the motor vehicle. At low
• the air-oil cooler does not provide sufficient cooling power at driving speeds.
• the oil must be directed to the air-oil cooler.
• flexible lines from the engine to the air-oil cooler are used due to the distances to be bridged and the flexible path of the oil. These flexible lines, which are usually designed as a hose, tend to leak after prolonged use.
• Another cooling device is the oil-water heat exchanger.
• This uses water or cooling water as the cooling medium. Due to the higher heat transfer coefficient of water, this heat exchanger has a higher cooling capacity with a smaller construction volume.
• the coolant, more precisely the water, and oil are carried in a pipe system made of hoses or pipes.
• the use of pipes and hoses is with regard to the connections of the pipes and hoses to one another or to the engine or the Oil-water heat exchanger disadvantageous, since the connection tend to leak relatively quickly, especially at the connection points. Furthermore, the fluid mechanical properties of the connections are disadvantageous, since the connections sometimes lead to large resistances in the line system.
• a third cooling device is the oil-water heat exchanger module with an oil filter.
• This solution overcomes some disadvantages of the cooling devices listed above.
• the advantage of the modular design is that the oil-water heat exchanger module has a compact design.
• the oil filter is designed as a filter cartridge, which is flanged to the heat exchanger.
• the oil line system is designed as a channel integrated in the module housing, which significantly reduces the risk of leaks with regard to the oil line.
• the flow of the media - coolant / oil - flowing in the channels takes place one after the other, i.e. in the manner of a series connection.
• the channels build longer, which leads to a larger construction volume.
• the length of the channels results in a greater total resistance of the line system, so that these also have to be compensated for by a larger dimensioning of the flow cross sections of the line system without accepting a loss of performance.
• a goal of such cooling systems in addition to cooling is to keep the pressure difference in the cooling module as low as possible, since this adds up to the total pressure drop in the entire engine system and a Pressure drop represents loss of effectiveness. The higher the pressure drop, the higher the loss of effectiveness.
• the cooling medium flows through the cooling module at high speed, that is to say it has a short residence time in the cooler module or cooler package, as a result of which the cooling medium can absorb and transport little thermal energy, and thus results in less effective cooling .
• the water circuit in the cylinder block and in the cylinder head must also be set separately, that is, it is necessary to readjust the water circuit in the cylinder block and the cylinder head. This creates an additional effort for adjustment work.
• This object is based on a radiator module according to the preamble of claim 1, an engine block according to the preamble of claim 6, an engine cooler module arrangement according to the preamble of claim 7 and a cooling method according to the preamble of claim 10 in conjunction with its characterizing features solved .
• Advantageous developments of the invention are specified in the claims dependent thereon.
• the invention includes the technical teaching that the module coolant channel formed in the housing of the cooler module is at least partially designed as a bypass channel fluidly connected to the oil / coolant heat exchanger to the engine coolant channel in order to divide the coolant flow into two partial flows, and to effect a parallel connection of the coolant flows.
• the module coolant channel can have an additional bypass channel in at least one section or can be designed entirely as a bypass channel.
• the bypass channel can be branched off from a section of the engine coolant channel which is formed in the engine block or already branch off from the water pump.
• any other cooling unit suitable for oil cooling can also be used as the cooling unit for oil cooling.
• This solution has the advantage that the total length of the line system is shortened by the bypass channel and the associated parallel connection of the coolant.
• the coolant used for cooling no longer passes through the heat-emitting engine and is then fed to the heat exchanger, but is fed to the heat exchanger parallel to the passage through the engine.
• the temperature of the coolant when entering the heat exchanger is thus significantly lower, as a result of which a significantly improved cooling capacity is achieved in the heat exchanger.
• Water is preferably used as the coolant. This allows the cooling circuit to be connected directly to the internal water circuit.
• the water is preferably taken directly behind the water pump. It is therefore advantageous that the bypass channel is arranged as close as possible to the water pump.
• the water is still little heated due to the heat that is given off by the engine to the cooling water, so that a relatively low water temperature is achieved when the water flows into the heat exchanger.
• the temperature difference between the entering cooling water and the oil to be cooled is greater than in conventional solutions, which significantly improves the cooling performance.
• the water circuit in the heat exchanger is connected in parallel to the water circuit through the engine block.
• the high pressure difference results in a longer dwell time of the cooling medium in the cooler package or cooler module, as a result of which a larger amount of heat can be absorbed by the coolant or cooling medium and a more effective cooling capacity can thus be achieved.
• the improved heat absorption means that fewer cooling plates are required in the cooler module compared to conventional cooling systems for the same cooling performance. This saves installation space. Overall, the invention thus also results in an increase in the cooling efficiency and thus also a reduction in the cost.
• the module coolant channel is designed to be fluidly detachably connected to a corresponding engine coolant channel in order to guide the coolant flow flowing through an engine block of the engine through the cooler module.
• part of the existing engine coolant channel can be used to transport the cooling water.
• the cooling water is then led through the module to the heat exchanger. This eliminates the need for an external hose line since the motor duct and the bypass duct are each integrated in the module housing.
• the heat exchanger is preferably arranged in the immediate vicinity of the engine, as a result of which the bypass channel length is made relatively short and a compact engine cooling module arrangement is possible.
• bypass channel transports a partial flow of the coolant to the oil cooler arranged on the housing and away from it again.
• the oil cooler is arranged on the cooler module. By connecting the coolant flow in parallel, a partial flow is discharged through the bypass duct. This is led to the oil cooler.
• Cooling water is preferably provided as the coolant. This can be branched off from existing cooling water pipes without having to provide an additional coolant circuit with an additional coolant for supplying the coolant circuit.
• One measure which improves the invention particularly provides that the oil / coolant heat exchanger is at least partially integrated into the module housing.
• a very compact cooler module is realized, which has a short channel length.
• the compact module is easy to assemble and handle with little effort.
• the at least partial integration of the heat exchanger in the cooler module ensures a safer and more reliable mounting, which also ensures an improved vibration behavior of the module.
• the module housing preferably has at least one integrated oil channel for guiding the oil to and from it
• Oil-coolant heat exchanger and / or the oil filter are also integrated in the housing means that external lines are no longer required, which further reduces the risk of leakages.
• the invention further includes the technical teaching that an engine block for cooling an oil circulating in an oil circuit of an engine by means of a coolant comprising at least one integrated engine coolant channel for transporting the coolant is provided, the engine coolant channel being fluid at least in one section has bypass channel connected to the oil-coolant heat exchanger in order to transport or guide one of the two coolant partial flows connected in parallel to and away from the oil-coolant heat exchanger.
• the bypass channel should be as close as possible to that
• Branch coolant cooler from the engine coolant passage to branch a coolant with a temperature as low as possible.
• This solution offers the advantage that the bypass duct is formed directly in the engine block or in the engine block housing, so that an additional module can be dispensed with. This means that fewer components are required overall.
• an engine cooler module arrangement for cooling an oil circulating in an oil circuit of an engine by means of a coolant comprising an engine with an engine block, at least one engine coolant channel integrated in the engine block and one with the engine block comprises fluidically connected cooler module, wherein the cooler module is connected to the engine block such that the at least one engine coolant channel and the at least one module coolant channel or the engine coolant channels and the module coolant channels are fluidly connected to one another to form a closed cooling line system ,
• the embodiment listed here is made in two parts, that is, with an engine and a cooler module.
• the engine block or the engine block housing can be produced with less effort.
• the cooler module can be integrated in the engine block, the cooler module or the channels formed in the cooler module replacing part of the channels otherwise located in the engine block. In this way, the installation space of the engine cooler module arrangement can be further reduced, so that an additional installation space is created.
• An oil / coolant heat exchanger, through which the oil flows, can be arranged in this, for example, as a cooler plate pack.
• the cooler module is at least partially integrated in the engine block, so that at least one area of the cooler module is in the engine block is designed to be integrated so that the at least one engine coolant channel can be at least partially replaced by the module coolant channel and / or the bypass channel.
• the at least partial integration of the cooler module in the engine block ensures a reliable and secure mounting of the module.
• This arrangement provides an engine cooling module arrangement that is optimized with regard to the vibration behavior. The cooler module vibrates less due to the partial integration, so that damage or functional impairments due to vibrations are largely avoided.
• At least one control unit for regulating the oil flow in the oil circuit is additionally formed. So the amount of oil flowing through the oil channel can be controlled depending on the need and application.
• the invention also includes the technical teaching that a cooling method for cooling an oil circuit of an engine by means of a coolant flowing in a cooling circuit formed by channels through an oil-coolant heat exchanger is provided, with an engine block and / or a cooler module comprising the steps: Directing the coolant through a first portion of the cooling circuit that passes through the engine block, directing the coolant through a second portion of the cooling circuit that passes through the oil cooler, and closing the cooling circuit, the steps of directing the coolant through a first portion and passing the Coolant through a second section in parallel.
