Definitions

  • the invention relates to a radiator for a heating system of a motor vehicle with a fin / pipe block through which the air to be heated can flow, and which has at least one row of pipes arranged in a heat-conducting manner between the fins.
  • Such a radiator is generally known for motor vehicles.
  • the radiator has a fin / tube block assembled from round or flat tubes and corrugated fins or corrugated fins, to each of which a water box is connected on both ends.
  • Coolant liquid which is heated by the cooling of the motor vehicle engine, is passed through the pipes of the radiator.
  • the corrugated fins or corrugated fins enclosing the tubes are traversed by air across the tubes, the air being warmed up due to the heat-conducting properties of the corrugated fins or corrugated fins.
  • the engine heat generated is not sufficient to sufficiently heat the air flowing through the fin / tube block to heat the passenger compartment.
  • in motor vehicles with an internal combustion engine only after the warm-up of the Motor achieves an effective heating power, because only then is the coolant liquid warmed up accordingly.
  • the object of the invention is to provide a radiator of the type mentioned, which can be electrically heated with simple structural measures and without requiring additional installation space.
  • the tubes are in the form of PTC heating tubes which have cladding tubes provided with integrated PTC heating elements.
  • This measure means that no additional installation space is required for the arrangement of PTC heating elements, since the installation space available for the tubes in the fin / tube block is used in a simple manner for the integration of the PTC heating elements.
  • the arrangement of the PTC heating elements in the cladding tubes results in a compact structure with defined dimensions that do not go beyond the dimensions of the tubes of the finned tube block. The outer dimensions of the fin / pipe block and thus the radiator do not change.
  • the air flowing through the radiator is heated even if the tubes of the fin / tube block either do not have liquid or cold liquid flowing through them will.
  • the cladding tubes with the PTC heating elements are arranged in the radiator either in connection with tubes through which coolant flows, so that the PTC heating elements represent additional heating for the radiator.
  • all tubes of the finned tube block of the radiator be replaced by cladding tubes provided with PTC heating elements, so that an exclusively electric radiator results, the dimensions of which correspond to the known coolant radiators.
  • the heating power of the PTC heating elements and the dimensioning of the fins surrounding the assigned cladding tubes are matched to the heat absorption capacity of the air flowing through the fins. This coordination is intended to prevent the PTC heating elements from heating up adjacent pipes through which coolant flows.
  • the PTC heating elements are only intended to heat the air.
  • every second tube in the fin / tube block is replaced by a PTC heating tube having a cladding tube with PTC heating elements. This results in an even distribution of both types of heating, so that either only the PTC heating elements or only the coolant tubes or both heating options can be in operation in combination.
  • the cladding tubes are integrated components of the fin / tube block.
  • the cladding tubes are therefore integrated together with the corresponding fins and tubes of the fin / tube block in one operation, so that there is no additional structural effort for the integration of the cladding tubes into the radiator.
  • the cladding tubes are advantageously soldered together with the fin / tube block, or the cladding tubes are including the PTC elements integrated into the fin / tube block by mechanical joining.
  • the PTC elements for a cladding tube are combined in a frame adapted to the cladding tube, which can be inserted into the cladding tube.
  • the PTC elements are preassembled into a slide-in component in the form of the frame and, in this compact design, can be easily inserted into the corresponding cladding tube from an open end.
  • the PTC elements are arranged watertight in the cladding tube. This prevents corrosion that could impair the functionality of the PTC elements.
  • an insertion side of the frame is wedge-shaped. This measure makes it easier to insert the PTC elements into the assigned cladding tube.
  • all PTC heating tubes are connected to a common circuit. As a result, all PTC heating elements are switched on and off together. The result is homogeneous electrical heating.
  • a radiator according to FIGS. 1 and 2 has a fin / tube block arranged between an upper water tank (1) and a lower water tank (2).
  • the fin / tube block is provided with several flat tubes (6) running between the two water tanks (1, 2), between which heat-conducting corrugated fins (7) are arranged as fins.
  • the upper water tank (1) is divided into an inflow and an outflow area by a partition (3).
  • the inflow area of the water tank (1) is provided with an inflow connection (4) and the outflow area with an outflow connection (5).
  • the radiator is connected by means of its two connections (4 and 5) in a manner known per se to a coolant circuit for an internal combustion engine of the motor vehicle.
  • the radiator can be used in both passenger cars and commercial vehicles.
  • every second flat tube (6) connecting the two water boxes (1 and 2) to one another is replaced by a respective PTC heating tube (8), each of which represents a cladding tube provided with PTC elements.
  • a total of five PTC heating tubes (8) are arranged, which are each inserted between two adjacent flat tubes (6).
  • Each PTC heating tube (8) is thermally conductive in connection with the respectively adjacent corrugated fins (7), the heating power of the PTC heating elements arranged in the PTC heating tube (8) being dimensioned such that only heating of the adjacent corrugated fins (7) , but not the flat tubes (6) connected to them.
  • the dimensions of the PTC heating tubes (8) essentially correspond to those of the flat tubes (6).
  • each PTC heating tube (8) has a cladding tube which, in the exemplary embodiment, consists of aluminum.
  • each cladding tube is part of the fin / tube block and is soldered together with the flat tubes (6) and the corrugated fins (7).
  • the PTC heating elements are then inserted into the corresponding cladding tubes and electrically connected to one another.
  • a ground tap (10) for forming the electrical circuit is provided on the upper water tank (1). All positive poles of the PTC heating elements are connected to a common positive conductor (9) leading out to the side of the fin / tube block.
  • the radiator according to FIGS. 3 and 4 corresponds in terms of its functional structure to the radiator according to FIGS. 1 and 2.
  • corrugated fins (7a) are provided in this radiator as fins, which together with the flat tubes (6a) and PTC heating tubes (8a) are mechanically joined together to form a fin / tube block.
  • the PTC heating elements for a cladding tube according to FIGS. 9 and 10 are combined in a frame, by means of which a compact PTC insertion part is formed for each cladding tube.
  • the rib / pipe block is first cassetted. When inserted into the cladding tubes, the PTC insert parts are clamped from above with the corrugated fins (7a). The subsequent expansion of the flat tubes (6a) additionally clamps the PTC insert parts in the associated cladding tubes, so that the PTC heating tubes (8a) are adequately secured in the fin / tube block.
  • the PTC insert parts are first inserted into the corresponding cladding tubes and then the cladding tubes together with the PTC insert parts are inserted between the corrugated fins (7a) and braced with them.
  • the cladding tubes or the PTC insertion parts are designed in a wedge shape on their insertion side in order to facilitate insertion.
  • the radiator according to FIGS. 5 and 6 corresponds essentially to the radiator according to FIG. 3, but the radiator has two rows of pipes arranged one behind the other. These rows of tubes are held by means of a corrugated fin package (7b).
  • the rear row of tubes in FIG. 6 represents a row of liquid-carrying tubes and consists of eleven flat tubes (6b).
  • every second flat tube (6b) is replaced by a PTC heating tube (8b).
  • the electrical connections of the PTC heating pipes (8b) with the negative pole (10b) on the upper water tank (1b) and a corresponding positive pole (9b) led outwards correspond to the previously described exemplary embodiments.
  • the radiator is either soldered or mechanically joined.
  • the PTC heating tubes (8b) in the front tube row of the fin / tube block serve as additional electrical heating in accordance with the previously described exemplary embodiments.
  • the radiator according to FIGS. 7 and 8 can only be heated electrically.
  • This heater is not connected to a coolant circuit of an internal combustion engine of the motor vehicle, but is intended to replace a corresponding liquid heater.
  • this radiator corresponds to the dimensions of a liquid radiator.
  • the water boxes are omitted.
  • this radiator can be connected to a heater that is already present in a motor vehicle or is designed for such a motor vehicle, if the motor vehicle has an electric motor.
  • Such a radiator can also be used in low-heat engines, such as optimized diesel engines.
  • the flat tubes (13) of this radiator have no liquid-carrying function, but only contribute to the stability of the finned tube block.
  • the flat tubes (13) are held on their upper end by an upper support (11) and on their lower end by a lower support (14).
  • the radiator has a corrugated fin package (12) corresponding to the known radiators.
  • several PTC heating tubes (15) are inserted between two flat tubes (13) into the plate pack (12) and held mechanically or by soldering in this plate pack.

A form-fitting fixation of the cladding tubes relative to the corrugated fin packs is thus achieved.
  • Each PTC heating tube (15) has a flat, thin-walled aluminum cladding tube (20), the cross section of which corresponds to the cross section of the flat tubes (13).
  • An insertion frame (22) made of plastic is inserted into this cladding tube (20), on which five PTC heating elements (19) are held. All PTC heating elements (19) rest on a plus conductor (18) made of aluminum, which is spaced apart from the inner wall of the cladding tube (20) by means of insulation.
