Abstract
A heat exchanger unit (10) comprises a core (25) and manifold (22, 23) assembly (14) mounted in a rectangular sub-frame (13). The sub-frame (13) comprises a U-shaped member (20) the opposed limbs (24) of which form confronting channels receiving side portions of the assembly (14), and a cross-member (21) secured to the assembly (14) and releasably secured to the ends of the limbs (24) to complete the rectangular sub-frame (13) and retain the assembly (14) in it. The unit (10) is fitted to a vehicle with the U-shaped member (20) in an inverted position so that with the cross-member (21) disconnected from it the assembly (14) can be slid into and out of the sub-frame (13) from beneath the vehicle.
Claims8
A heat exchanger unit which includes a core and manifold assembly supported by and mounted in a rectangular sub-frame, characterised in that the sub-frame comprises a U-shaped member, in that the opposed parallel limbs of the U-shaped member form confronting channels to receive side portions of the assembly, and in that the sub-frame further comprises a cross-member secured to the core and manifold assembly and releasably secured to the U-shaped member to retain said assembly in said channels.
A heat exchanger unit as claimed in any one of the preceding claims in which the cross-portion of the U-shaped member joining the parallel limbs thereof is provided with anti-vibration means providing support for for said assembly.
A heat exchanger unit as claimed in any one of the preceding claims which is fitted to a vehicle with the U-shaped member in an inverted position so that the core and manifold assembly can be slid into and out of the sub-frame from beneath the vehicle.
A method of removing a radiator from a heater exchanger unit in which a rectangular sub-frame includes a cross-member which is secured to one end or margin of the radiator, which method is characterised in that said cross-member is separated from the rest of the sub-frame to allow the radiator to be slid out of the rest of the sub-frame in a direction extending in the installed plane of the radiator.
