Description

  The invention relates in particular to a structural mechanism for a heat exchange device of a motor vehicle.

In automobiles, various heat exchange devices are used in, for example, automobile air conditioners, cooling circuits, or cooling circuits for cooling gear oil or steering booster oil. When used in an automobile, since only a limited structural space can be used, there is always a problem that individual heat exchange devices must be provided with as little space as possible. In addition, more and more value is placed on manufacturing individual components at a low price.
German Patent No. 4238853 European Patent Application No. 0669506

  Accordingly, an object of the present invention is to provide a structural mechanism for a heat exchange device that requires a relatively small space and is more advantageous from the viewpoint of manufacturing cost.

  According to the invention, this object is achieved by a structural mechanism according to claim 1. Advantageous embodiments and refinements are the subject of the dependent claims.

  The structural mechanism of the invention is at least one first heat exchange device, at least one inlet for a first flowable medium, a collection and / or distribution pipe for a first flowable medium. A plurality of first flow-through devices for the first flowable medium, a collection device (hereinafter referred to as a collector), and at least one outlet for the first flowable medium, 1 heat exchange device. Furthermore, according to the present invention, a second heat exchange device is provided adjacent to the first heat exchange device, the second heat exchange device being at least one for the second flowable medium. An inlet, a collection and / or distribution pipe for a second flowable medium, a plurality of second flow-through devices for a second flowable medium, and at least one for said second flowable medium Has two outflows. The collection and / or distribution pipe is preferably a long pipe. The second heat exchange device may extend longer than the first heat exchange device, particularly in the longitudinal direction.

  The collection and / or distribution pipe serves to distribute the flowable medium to a plurality of flow-through devices or to collect the flowable medium that reaches the collection and / or distribution pipe from the flow-through device.

  For this purpose, the collection and / or distribution pipe comprises a plurality of openings through which the end portions of the flow-through device can be inserted. The collection and / or distribution pipe has a cross-section selected from the group of cross-sections including circular cross-sections, elliptical cross-sections, polygonal cross-sections, and combinations thereof.

  The flow-through device is a long tube, particularly a flat tube. These individual flat tubes may comprise one or more spaced channels for the flowable medium.

  The collector preferably has two openings. These openings function as an inflow portion and an outflow portion for a flowable medium. In addition, a drying and / or filtering device is preferably provided in the collector through which the flowable fluid flows. This type of drying and / or filtering device is described in US Pat. This type of collector can be used within the scope of the invention, in particular when the first heat exchange device is configured as a condenser of an automotive air conditioner. Patent document 1, especially the location of the general description in column 1 line 1 to column 2 line 22 and the description of the preferred embodiment in column 2 line 45 to column 5 line 42 are hereby incorporated by reference. Is incorporated by reference.

  Furthermore, the collector used within the scope of the invention may also have the form as described in US Pat. Also in this specification, the general description of the first column, the first line to the first column, the 48th line, and the specific drawing explanation from the second column, the fourth line to the fifth column, the 22nd line are also included in the present application. Subject to disclosure. In this case, this object is particularly important when a filter device is to be installed in the collector.

  Arranging the second heat exchange device adjacent to the first heat exchange device means that these heat exchange devices are not located spatially apart from each other, but are provided closest to each other. Particularly preferably, it is constructed in one piece or is held by the same frame member. In this case, it is preferable that the 2nd heat exchange apparatus is provided in the longitudinal direction side in contact with the longitudinal direction side of the 1st heat exchange apparatus.

  Therefore, the second heat exchange device is formed integrally with the first heat exchange device, preferably by manufacturing simultaneously. That is, both heat exchangers can be brazed simultaneously during manufacture, thereby reducing manufacturing costs. In addition, the space in the engine room can be saved by mounting as a single unit.

  In a preferred embodiment, the at least one collection and / or distribution line for the first flowable medium functions as a collection and / or distribution line for the second flowable medium. For this purpose, at least two chambers are provided in the collection and / or distribution pipe, whereby both media are separated from each other.

  Furthermore, this means that the at least one collection and / or distribution pipe is not only a flow device through which the first flowable medium flows, but also a flow device through which the second flowable medium flows. Can also be understood as merging. The structural mechanism preferably has two collection and / or distribution pipes, both collection and / or distribution pipes each functioning to accommodate substantially all of the first and second flow-through devices. Preferably, two collection and / or distribution pipes are provided in which the first flowable medium and the second flowable medium are each separated from one another in a predetermined manner. Flowing in the part.

  It is preferred that the flow device has two end portions. Each of these end portions protrudes into the collection and / or distribution pipe. In that case, each end portion preferably projects into two different collection and / or distribution pipes. However, it is also possible for the end portions to protrude into the same collection and / or distribution pipe. In that case, the corresponding collection and / or distribution pipes have a first space in which the first end portion of the flow device protrudes and a second space in which the second end portion of the flow device protrudes. It is preferable to have at least one separation device separating the collection and / or distribution pipes. In this way, the end on the inflow side and the end on the outflow side of the collection and / or distribution pipe can be separated from each other.

  In a further preferred embodiment, the plurality of first flow devices are provided in parallel to the plurality of second flow devices. This means that the longitudinal directions of the flow devices are parallel to each other, and the heat exchange medium that flows between the flow devices, especially the cooling fins that improve the heat exchange by air, etc. Is preferably provided between the individual flow-through devices. By interrupting the collection and distribution pipes respectively, it is possible to separate the first flow device from the second flow device.

  The first flow device preferably has substantially the same geometric profile as the second flow device. This eliminates the need to create different types of flow-through devices, thus facilitating manufacturing. However, it may also be advantageous if the first flow device has a different geometric profile than the second flow device.

  Also preferably, the internal geometry of the first flow device and the second flow device may be configured to be the same.

  However, the internal geometry is chosen to be different, especially when the viscosity of the first flowable medium is very different from the viscosity of the second flowable medium.

  In this case, the flow-through device has one or more parallel fluid paths, each of which has a circular cross section, a rectangular cross section, or a triangular cross section. In this case, each cross-sectional shape is configured relatively accurately in terms of geometry, but within the scope of the present invention, especially in the case of a rectangular cross-section or a triangular cross-section, the transition part is rounded. In particular, it may be configured to be concave.

  The hydraulic diameter of each flow section is preferably in the range of 0.3 mm to 10 mm. In this case, the hydraulic diameter is obtained by an equation calculated by multiplying the cross-sectional area of the pipe by 4 and then dividing by the wet circumference of the pipe.

  The first flowable medium is preferably a refrigerant of an automobile air conditioner. In this case, the first heat exchange device is configured as a capacitor. Alternatively, the first flowable medium may be a coolant. In the case of the coolant, the first heat exchange device is preferably configured as an automobile cooling device, and the cooling water flowing through the automobile engine is cooled by the cooling device.

  The hydraulic diameter in the case of the first heat exchange device is preferably between 0.4 mm and 4 mm, particularly preferably between 0.4 mm and 1.3 mm.

  The second flowable medium is preferably automotive hydraulic fluid and is distributed to engine oil for lubricating internal combustion engines, gear oil for lubricating automatic transmissions or manual transmissions, and wheels driving engine drive torque. Provided for lubricating a differential machine (in this case, the differential machine may be a separate differential machine with a separate drive shaft, or may be a distributed differential machine of a four-wheel drive vehicle). Preferably selected from the group including gear oil and the like. Further, the second fluid medium may include steering booster oil, brake fluid, or hydraulic oil for driving the superstructure of a commercial vehicle.

  The hydraulic diameter in the case of the second heat exchange device which functions to cool the hydraulic fluid of the vehicle is preferably between 0.3 mm and 10 mm, particularly preferably between 0.4 mm and 8 mm.

  The oil cooler, i.e. the tube wall of the second heat exchange device, preferably has a thickness of between 0.2 mm and 1.5 mm, particularly preferably between 0.35 mm and 1.0 mm.

  Since gear oil coolers and condensers work under different conditions, especially at different temperatures or temperature differences, undesirable thermal stresses can occur in the intermediate region between the oil cooler and condenser. Thus, for example, in winter the condenser remains cold because the vehicle air conditioner is not in operation. Nevertheless, the oil cooler is heated and cooled when the vehicle is run and stopped. In so doing, the oil cooler tube expands and contracts again, while the condenser tube remains unchanged.

  For the above reasons, it is preferred that the oil cooler tube be constructed to be strong enough to withstand the stresses caused by expansion and contraction. For the reasons described above, the wall is preferably thicker than the tube wall in the case of a single drive oil air cooler where no distortion due to heat occurs. The wall thickness between 0.35 mm and 1.0 mm ensures sufficient strength while reducing material consumption.

  In a further preferred embodiment, the at least one collection and / or distribution line has at least one separation device, whereby a space for the first flowable medium is provided for the second flowable medium. Separate from space. In this case, it is preferable that a partition plate that cannot pass either flowable medium is provided inside the collection and / or distribution pipe.

This means that a plurality of first flow devices provided parallel to each other are followed by at least one continuous device in which no medium flows, which further comprises: A plurality of second flow devices follow through which the second flowable medium flows. This flow device, where the medium hardly flows through, functions to insulate the first flow device from the second flow device. The insulation between these “blind” flow devices and the adjacent first and second flow devices are each configured to have cooling fins. Alternatively, it may be configured not to have cooling fins. In a further preferred embodiment, the end portion of the flow-through device, through which the fluid hardly flows, protrudes into the part of the collection and / or distribution pipe that is delimited on both sides by the partition plate. In this case, there is almost no fluid medium between the two partition plates.

  In a further preferred embodiment, the collector is provided substantially parallel to the collection and / or distribution pipe. In this case, the collector has a cross-section selected from the group of cross-sections including circular and polygonal cross-sections and their mixed shapes.

  The collector is preferably shorter than the collection and / or distribution pipe. In particular, the collector preferably has a length that approximately matches the length of the portion of the collection and / or distribution pipe through which the first flowable medium flows. This means that the collector has approximately the same length as the first heat exchange device. However, the length of the collector may be greater or less than the length of the first heat exchange device.

  In a further preferred embodiment, the collector is provided laterally offset with respect to the flow device, more precisely the plane defined by the entire flow device.

  In a further preferred embodiment, the number of first flow devices is greater than the number of second flow devices. This means that the first heat exchange device also occupies a larger heat exchange surface, more precisely, more space than the second heat exchange device.

  Preferably at least one collection and / or distribution line, particularly preferably both collection and / or distribution lines, have a plurality of separators or dividers. In this way, the first flowable medium can be reciprocated many times between the collection and distribution pipes within the first heat exchange device.

  In a further preferred embodiment, at least one further heat exchange device is provided in contact with the first heat exchange device or the second heat exchange device. In this case, the first heat exchange device can preferably be provided between the second heat exchange device and the further heat exchange device.

  In a further embodiment, a second heat exchange device or a further heat exchange device is provided substantially parallel to the collection and / or distribution pipe. Similarly, the second heat exchange device may be configured such that the surface defined by the first flow device and the surface defined by the second flow device are parallel to each other. Is possible. In this case, the second heat exchange device is provided upstream or downstream of the second heat exchange device in the direction in which air flows.

  The second heat exchange device is preferably a device selected from the group of heat exchange devices including an oil cooler for a steering booster, a gear oil cooler, and the like.

  It is preferable that the inflow part and the outflow part of a 2nd heat exchange apparatus are provided in the edge part which the 2nd heat exchange apparatus opposes. This means that in this embodiment, a second flowable medium, preferably oil, flows into the first collection and distribution pipe and from there substantially the entire second flow device. And is collected in the second collection and distribution pipe and then out through the outflow.

  In a further embodiment, the inflow portion and the outflow portion of the second heat exchange device are provided at the same end portion of the second heat exchange device. In this case, the second flowable medium first flows from the first collection and / or distribution line to the second collection and / or distribution line and from there through a predetermined number of flow devices. Return to the first collection and distribution pipe through the further part of the excess device to the outflow. In this case, it is preferable that the collection and distribution pipe provided with the inflow part and the outflow part have a separation device or a partition plate provided perpendicular to the longitudinal direction of the pipe.
