Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1.
  • Heat exchangers of known design have a tube / rib block, which consists of pipes or flow passages through which a first fluid can flow and ribs which can be flowed over by a second fluid.
  • Tubes and ribs are in heat-conducting connection; For example, they are soldered or mechanically connected.
  • the tubes have over the block protruding pipe ends, which each open into a collection or distribution box, ie communicate with this on the first fluid.
  • the first fluid for. B. a coolant is supplied to the heat exchanger via a connecting piece (inlet nozzle) and withdrawn after flowing through the tube / rib block via a second connecting piece (outlet nozzle) again.
  • the tube / fin block As it flows through the tube / fin block, heat is transferred from one fluid to the other via the fins. For example, air flows through the tube / fin block, which is heated by the coolant.
  • the tube / fin block generally has a plurality of tubes, e.g. As round tubes or flat tubes, which can be arranged in one or more rows.
  • the tubes can be hydraulically connected in parallel, ie all flowed through in the same direction, or individual pipe groups can be connected in series, so that they are flowed through successively and the fluid covers a longer path in the heat exchanger.
  • the deflection of the fluid flow, which from a Pipe group exits, takes place in the collection boxes, which have divided by partitions diverting chambers.
  • a deflection of the fluid flow can either transversely to the second fluid flow, for. B. an air flow - it is then called a deflection in the width of the heat exchanger - or in or against the flow direction of the second fluid (air flow) - one then speaks of a deflection in depth.
  • an at least two-row or two-pipe arrangement of the tubes or flow channels is required.
  • a double-flow design with deflection in the depth can be realized for example by a flat tube with inner partition.
  • radiators of a heating and air conditioning such a temperature stratification is desired: So should the emerging from the radiator in the upper air cooler and the exiting air in the lower area to be warmer. The cooler air is supplied to the head area of the vehicle occupant and the heat air to the foot area of the vehicle occupant.
  • a so-called right / left separation i. H. independent heating of the driver and front passenger side usual.
  • the applicant has been known such a radiator for a motor vehicle heating system, which has a right / left separation.
  • the radiator is divided into two blocks, which are supplied from a common flow with coolant, but each have their own return with flow control. This allows the flow in each sub-block (for right or left) to be set independently, thereby individually controlling the air temperature for the driver and front-passenger sides.
  • the known radiator has additional means to produce a temperature stratification in the above sense (cool head - warm feet).
  • transversely extending distribution pipes are provided both in the lower and in the upper collecting box of the radiator, which effect a different loading of the radiator pipes and thus a stratification of the air temperature.
  • the known heating system is referred to as a water-regulated system, since the air temperature is adjusted via the regulation of the coolant throughput. In air-controlled systems, the coolant flow rate is not regulated, but hot and cold air streams are brought by mixing to the desired temperature.
  • the first fluid flow supplied to the heat exchanger can be deflected both in width and in depth, not in succession but simultaneously.
  • the incoming fluid flow is divided into a first partial flow, which is deflected in depth, and a second partial flow, which is deflected in width.
  • the advantage is achieved that at least two different temperature zones are created for the exiting fluid flow in a relatively narrow space, namely, a first, warm zone from the fluid inlet to the division and deflection of the fluid flow, a second, approximately lukewarm zone, which adjacent to the warm zone is placed, and in a third, cold zone.
  • the tube / rib block can be soldered or mechanically be made, ie consist of flat tubes with corrugated ribs or round or oval tubes with flat ribs.
  • the first collection box has an inlet chamber and the second collection box a deflection chamber, in which the division and deflection of the fluid flow takes place.
  • the first collection box further has an exit chamber which is separated from the entry chamber by a longitudinal dividing wall.
  • an outlet chamber section is arranged in the first collection box, into which the second partial flow diverted into the width opens.
  • the exit chamber section is in fluid communication with the exit chamber.
  • the heat exchanger can be extended by "reflection" in a heat exchanger with separate right / left control. This is done by providing a second inlet chamber with a further connection piece, extended collection boxes with a further deflection chamber and a further outlet chamber portion, which is combined with the first outlet chamber portion.
  • the heat exchanger is designed as a radiator of a Kraft mecanicungs- and / or air conditioning, ie the manifolds and pipes are flowed through by a coolant of a cooling circuit of an internal combustion engine, while the ribs are overflowed by ambient air.
  • the radiator according to the invention is advantageously part of a water-regulated heating system withrezlLinks control. Due to the air temperature profile according to the invention are different tempered air streams, which can be taken directly behind the radiator through channels and the corresponding points in the vehicle can be supplied. For example, the cold air is supplied to the defrost and the head area of the vehicle occupant and the warm air to the foot and rear area of the vehicle. This can be dispensed with devices for mixing cold and warm air such as channels, flaps and mixing rooms.
  • the two flow connection stubs are each arranged on the front side of the heat exchanger, with other arrangements, for. B. side or up abragend possible.
  • the return pipe is preferably also arranged frontally next to one of the two flow nozzles - here are arrangements on the side, top or center possible.
  • An advantage of a central arrangement of the return nozzle is a symmetrical flow in the second row of tubes.
  • the direction of flow of the air is preferably in the direction of the deflection in the depth (cross-DC) - the opposite direction (cross-countercurrent) is also possible.
  • the first partial flow can be throttled by a suitable choke element, so that the ratio of the mass flows changes in favor of the second partial stream: the coolant volume flow V 1 is thus relatively small and the volume flow V 2 relatively larger.
  • a suitable choke element may be formed as a baffle, which is preferably arranged in the outlet chamber section of the return pipe. The baffle is thus transverse to the flow direction of the exiting first partial flow and acts much like a baffle plate - thereby the desired throttling is achieved. The strength of the throttle effect can be adjusted by the arrangement and size of the baffle.
  • the entire radiator can be designed as a soldered all-aluminum heat exchanger, d. H. with flat tubes and corrugated ribs.
  • Fig. 1 shows a heat exchanger 1, which is designed as a radiator of a heating and / or air conditioning, not shown, of a motor vehicle.
  • the radiator 1 has a double-row or double-flow tube / rib block 2 with a first flat tube row 2a and a second flat tube row 2b.
  • the flow channels 2a, 2b can be formed by separate flat tubes or a common flat tube with a partition wall. Between the flat tubes are corrugated ribs, which are not shown.
  • Flat tubes and corrugated ribs are soldered together and form the tube / rib block 2, which of ambient air, represented by an arrow L, can be flowed through (an opposite air flow direction in the sense of a countercurrent flow is also possible).
  • the radiator 1 also has two manifolds, a first (upper), only partially illustrated collection box 3 and a second (lower) collection box 4, in which unillustrated pipe ends of the tube / rib block 2 open.
  • the upper header 3 which has a tube bottom 3a, is divided into a first inlet chamber 5, a second inlet chamber 6 and an outlet chamber 7, consisting of three communicating outlet chamber sections 7a, 7b, 7c.
  • the first inlet chamber 5 has a first inlet or feed pipe 8 and the second inlet chamber 6 has a second inlet or feed nozzle 9, the outlet chamber 7 with its sections 7a, 7b, 7c has an outlet or return pipe 10, wherein all nozzles are arranged frontally.
  • the outlet nozzle 10 may be arranged, for example, centrally and above the outlet chamber section 7b.
  • the first inlet chamber 5 is bounded by the tube bottom 3a, a central longitudinal partition wall 5a and a half transverse wall 5b (longitudinal partition wall 5a and transverse partition wall 5b may also be integrally formed as a longitudinal / transverse partition wall).
  • the symmetrically arranged and symmetrically formed second inlet chamber 6 is bounded by a centrally extending longitudinal partition wall 6a and a transverse half transverse wall 6b, wherein - as mentioned - the lid of the collecting tank 3 is not shown.
  • the lower collection box 4 has a first deflection chamber 11 and a second deflection chamber 12, which is partitioned off from the first deflection chamber 11 by a partition wall 13.
  • the illustrated embodiment has two Schuungsvorin and a common return and is thus suitable for independent heating of the driver and passenger side in a motor vehicle. Deviating from the illustrated embodiment, however, a "halved" heat exchanger or radiator is conceivable, which ends in the plane of the partition wall 13, d. H. has only one flow and one return.
  • the function of the radiator 1 in a Kratt familialoomungsstrom will be described below.
  • the radiator 1 is connected via the two supply line 8, 9 connected to the coolant circuit of an internal combustion engine of the motor vehicle, both heats are independently controllable with respect to their coolant flow rate (water-side control). It is considered at first only the left half of the radiator 1 with the flow pipe 8.
  • the coolant flow passes through the inlet chamber 5 in a tube group of the first row of tubes 2a and flows through them in the direction of the arrow V ⁇ , where V ⁇ denotes the coolant mass flow (mass per unit time).
  • the coolant thus flows into a first passage from the inlet chamber 5 in which is arranged in the lower header box 4 diversion chamber 11, where the total current V into two partial flows V 1, V 2 divided and is deflected in depth and in width.
  • V ⁇ V ⁇ 1 + V ⁇ 2 ,
  • the partial flow with the mass flow rate V ⁇ 1 passes according to the arrow V ⁇ 1 in the rear row of pipes 2b and flows through them from bottom to top.
  • the second partial flow V 2 is deflected according to the arrow V 2 in the width and flow both in the front and in the rear row of tubes up into the section 7b of the exhaust chamber 7.
  • the deflected in the depth partial flow V 1 passes after passing through the rear Tube row 2b in the section 7a of the outlet chamber 7, where both partial flows V ⁇ 1 and V ⁇ 2 reunite and emerge as a total flow through the return pipe 10.
  • temperature zones are shown as rectangles 1a, 1b, II and III in the right half.
  • the two fields Ia and Ib indicate a zone of relatively warm air, i. H. Air with a relatively high outlet temperature.
  • Zone II is a zone of lower air temperature and may be said to be lukewarm, while
  • Zone III is a zone of relatively low air temperature, i. H. less heated air.
  • the air these fields Ia, 1b, II III isolated taken and directed to the desired locations in the passenger compartment.
  • the warm air emerging from the fields Ia, Ib would be supplied to the footwell, while the cold air leaving the region III would be sent to the defroster jets.

  • the flow of the coolant corresponds to the in Fig. 1 , ie, the flow of coolant entering through the feed pipe 8 first flows downward in accordance with the arrow V ⁇ and is there - as in Fig. 1 shown - divided into two partial streams V ⁇ 1 and V ⁇ 2 , so that the first deflected in the depth partial flow V ⁇ 1 flows upwards and enters the outlet chamber section 7 a .
  • baffle 14 an approximately parallel and above the tube sheet 3a extending baffle 14 is arranged.
  • the coolant flow entering from the rear row of tubes 2 a into the outlet chamber section 7 a strikes the guide plate 14 approximately perpendicularly, which thus acts like a baffle plate and increases the flow resistance of the coolant flow or throttles the partial flow V 1 .
  • the guide plate 14 in the drawing on the left side of the radiator 1 of the entering through the right, not shown second inlet nozzle coolant flow increases.
  • the result of the arrangement of the guide plate 14 is a gleichrichte, ie approximately symmetrical temperature distribution, which compensates for the asymmetrical arrangement of the single outlet nozzle 10 (return pipe).
  • a symmetrical arrangement of the return neck 10 z. B. in the middle of the radiator, such a baffle would not be required.
  • the baffle 14 can be modified in terms of its overlap of the partial stream V 1 and with respect to its height above the tube plate 3a so as to achieve the desired air temperature distribution on the heater.
