A front construction of a motor vehicle body comprises a front base of the vehicle body and a heat exchanger support frame having an air passing aperture which is defined by upper and lower horizontal members and two mutually spaced side stays which extend between the upper and lower horizontal members. A skirt portion is integral with the lower horizontal member and extends along a lower portion of the lower horizontal member. The skirt portion faces forward with respect to the vehicle body keeping a given inclination relative to the heat exchanger support member to serve as an air guide for the air passing aperture. Recessed seat portions are integrally formed by the skirt portion, and fixing members are used for fixing the recessed seat portions to the front base.

Front construction of motor vehicle body and heat exchanger support frame used therefor

The gist of the present invention consists in an oil cooler for an automatic transmission, wherein opposite corners in a rectangular core made of a plurality of stacked plates are provided with a plate side oil passages, which are connected via an oil tank formed projectingly to the front side of the core, to oil inflow and outflow stud bolts. In the present invention, the opposite corners in the core are provided with plate side oil passages, which are connected via the oil tank formed projectingly to the front side of the core, to oil inflow and outflow stud bolts, which permits the whole core to be supplied with oil.

Oil cooler for automatic transmission

A core for a housingless oil cooler has alternate cooling water passageways and oil passageways, including two sets of aluminum plates coated on one side with a sacrificial corrosion layer and on the other side with a brazing filler metal layer, each plate having a peripheral rim projecting from the outer periphery. The plates of the first and second sets are assembled alternately and arranged so that the brazing filler metal layer coated on each plate of the first set is adjacent to the sacrificial corrosion layer of the next plate of the first set and the plates of the second set have a sacrificial corrosion layer opposed to the sacrificial corrosion layer of the adjacent plate of the first set to define a cooling water passageway therebetween, and the brazing filler metal layer on the outer surface of the peripheral rim of the plates of the second set is bonded to the inner surface of the peripheral rim of the adjacent plate of the first set.
