Definitions
- the invention relates to air-cooled coolers with cooling air flowing through them in succession Cooling levels according to the preamble of the main claim.
- Air-cooled coolers for internal combustion engines with a U-shaped flow of the liquid to be cooled with at least two cooling planes through which cooling air flows in succession are previously known from the document DE 34 33 370 A1.
- Groups of cooling tubes arranged one behind the other and in parallel and connected on one side via a connection space form a cooler unit, in which the outflow and the inflow for the medium to be cooled are arranged on the cooler side directly exposed to the cooling air.
- a first group of cooling tubes forming the first cooling level, to which cooling air is first applied on the upstream side, has the outflow for the medium to be cooled.
- the second group of cooling tubes which is subsequently acted upon by the cooling air and forms the second cooling level, is equipped with the inflow for the medium to be cooled.
- coolers with two successively acted upon by cooling air and the cooling planes flowing through the medium to be cooled from closely behind one another arranged first and second groups of cooling tubes. But it does not reveal any Means or suggestions for achieving high temperature difference between the Cooling tube groups.
- the invention is based on the object for generic air-cooled coolers for liquids to be cooled with a small inflow area, good efficiency and realize high temperature difference between inflow and outflow and advantageous can be used for vehicle units to be cooled.
- the object is achieved by the features mentioned in the characterizing part of the main claim.
- Coolers according to the invention are economically advantageous and can be implemented in a simple manner by arranging and connecting them in series.
- the cooler units form a cooling column by connecting them in series in the flow and, due to the lack of substantial direct heat transfer to one another, furthermore have a high temperature difference between inflow and outflow.
- Cooler 1 is an air-cooled cooler 1, preferably for liquids to be cooled, with at least two cooling levels through which cooling air flows Cooler units 2; 3 schematically shown for liquids to be cooled.
- At least two cooler units flow through one after the other 2; 3 arranged one behind the other without substantial direct heat transfer, the front cooler unit 2, which is acted upon first by the cooling air, is the Drain A2 arranged for the medium M to be cooled. That of the cooling air subsequently acted upon, rear cooler unit 3 assigns the inflow Z3 for the cooling medium M.
- a plurality of rear cooler units 3 can also be used are used, the last from which the heated cooling air is returned to the Free occurs, with the inflow Z3.
- the cooler units 2; 3 are in a housing 4 forming the cooler 1 arranged, which between the cooler units 2; 3 just a little Allows heat transfer and the cooling air KL between the cooling units 2; 3 leads or includes. With this design, the cooler units 2; 3 strong different temperature level.
- the flow direction of the medium M to be cooled in the one behind the other arranged and successively flowed through cooler units 2; 3 can be advantageous be the same, not shown.
- the opposite surface areas of the Arranged cooler units 2 through which cooling air KL flows; 3 each have a large temperature difference in such an embodiment.
- the rear cooler unit 3 has one larger flow cross-section for the already heated cooling air than the front, Cooling unit 2 acted upon directly by cooling air Flowing through both cooler units 2; 3 scored.
- the air-cooled cooler 1 Due to its favorable dimensions, the air-cooled cooler 1 with its Zu-Z3 and drain A2 of the medium M to be cooled directly on an aggregate be connected. It is thus possible for the cooler 1 to be connected to an assembly in the Front or rear area of a vehicle in or near the area of a Wheel arch cutout is arranged and thus favorably acted upon by cooling air.
- the cooler elements made of tubular or flat, with air are advantageous acted cooling lines provided lines formed.
- the front radiator element and / or the rear cooler element (3) can be single or multiple U-shaped flow.
- the lines provided with cooling surfaces are on the upstream or downstream side seen, arranged one above the other. See Fig. 2, it shows the view of the Cooler element 3 counter to the flow of cooling air KL in FIG. 1.
