Abstract
A unit core radiator is provided with support for the top tank and bottom tank so as to prevent the top and bottom tanks from vibrating relative to the support and at the same time to permit expansion and contraction of the core relative to the support. Mating members are carried by the top tank and the side channels and are urged against each other to form slip joints to allow limited movement between the tank top and the side channels in adjusting for temperature changes in the cooling fluid.
Claims8
A unit core radiator having a bottom tank, a top tank, and a heat exchange core extending between said bottom tank and said top tank, a support on which said bottom tank is carried, side channel supports attached to said support and extending upwardly adjacent said heat exchange core and projecting in overlapping relationship to said top tank, low friction means carried by said top tank in contact with said overlapping side support for supporting said top tank relative to said side channel supports, means encircling said side channel supports and said top tank and means on said encircling means for tightening said encircling means to urge said side supports into frictional engagement with said low friction means on said top tank whereby passing heated fluid through said radiator expands said heat exchange core to force the top tank and the low friction means on the top tank to move longitudinally relative to the side support.
In a unit core radiator having a bottom tank, a top tank, and a core extending between said bottom tank and said top tank, a support having a cradle and a pair of side channels attached to said cradle and extending in overlapping relationship to said top tank, in which the improvement comprises a slip joint means carried by said top tank and by said side channels, and means carried by said side channels for increasing the pressure in said slip joint means, whereby said slip joint means permits expansion and contraction of said core to move said top tank further away from or closer to said bottom tank.
