Abstract
In heat transfer devices, which are constructed as plate oil coolers for motor vehicles, an adapter plate is provided in order to achieve a compact construction with a joint fastening and with feeding openings which are accessible only from one side. The adapter plate is configured such that at least two, but preferably four different plate coolers can be supplied with the same coolant flow. This results in a particularly simple and compact construction.
Claims17
Heat transfer arrangement for motor vehicles, comprising:
- first and second heat transfer devices in which a liquid coolant and a liquid medium to be cooled are guided in adjacent layers which are separated from one another by heat transmitting walls,
- an adapter plate disposed to support the heat transfer devices, said adapter plate defining connection ducts between respective feeding and discharge bores of the first and second heat transfer devices, and
- a cover plate interposed between the first and second heat transfer devices and the adapter plate,
- wherein said cover plate includes:
- a joint connection piece for conducting coolant through the cover plate into a connection duct of the adapter plate,
- openings for transporting coolant from the adapter plate to the first and second heat transfer devices, and
- two additional connections for feeding and removing medium to be cooled in the first and second heat transfer devices supported side by side on the cover plate.
Heat transfer device according to claim 8, and further comprising further heat exchangers for cooling of transmission oil and diesel oil placed on respective blocks of the first heat transfer device and of the second heat transfer device and connections to said further heat exchangers for the coolant.
A method of making a heat transfer arrangement for motor vehicles, comprising:
- providing first and second heat transfer devices in which a liquid coolant and a liquid medium to be cooled are guided in adjacent layers which are separated from one another by heat transmitting walls,
- disposing an adapter plate to support the heat transfer devices, said adapter plate defining connection ducts between respective feeding and discharge bores of the first and second heat transfer devices,
- disposing a cover plate between the first and second heat transfer devices and the adapter plate,
- wherein said cover plate includes:
- a joint connection piece for conducting coolant through the cover plate into a connection duct of the adapter plate,
- openings for transporting coolant from the adapter plate to the first and second heat transfer devices, and
- two additional connections for feeding and removing medium to be cooled in the first and second heat transfer devices supported side by side on the cover plate,
- and fixedly attaching said heat transfer devices, cover plate and adapter plate together to form a multiple heat transfer device unit.
