Abstract
Heat transfer devices, particularly the radiators for internal-combustion engines of motor vehicles are provided with a fan shroud and a fan arrangement. In this case, the shroud must be adapted to the dimensions of the radiator in such a manner that it can be fastened on the coolant tanks. The fastening of the fan shroud is carried out at least partially on the bent outer edges of the fins of the finned tube block, such that differently dimensioned fan shrouds can be connected to different finned block locations.
Claims12
A radiator for an internal combustion engine driven motor vehicle, comprising:
- a finned tube block formed of a plurality of parallely extending tubes and a plurality of fins extending transversely of the tubes, at least some of said fins including bent over ends,
- a fan shroud,
- and a fastening strip connecting the fan shroud to the finned tube block,
- said fastening strip including two interlocking engageable L-shaped strip parts which form a U-profile clamped against said bent over ends of said fins,
- one of said L-shaped strip parts forming part of the fan shroud.
A method of making a radiator for an internal combustion engine driven motor vehicle, comprising:
- forming a finned tube block with a plurality of parallely extending tubes and a plurality of fins extending transversely of the tubes,
- bending ends of at least some of said fins to form bent over ends of said fins,
- providing a fan shroud including an L-shaped strip part,
- and fastening the fan shroud to the finned tube block by interlockingly engaging the L-shaped strip part of the fan shroud with another L-shaped strip part to form a U-profile clamped against the bent over ends of said fins.
