Report on Gallay Radiator Matrices and Oil Cooler. These matrices and the oil cooler were supplied to us for test by Messrs. Gallay, as being competitive with our present standard products. The radiator matrices etc. tested, were :- (1) A specimen test block of Gallay three row tube core, 17 1/4" square and 50 m.m. deep. (2) A Bentley radiator matrix to EB.518 but in Gallay three row tube core and 50 m.m. deep. (3) A Gallay oval tube type oil cooler matrix, to replace our standard oil cooler matrix. The tests carried out on (1) above were done for us by the Harrison Radiator Corporation of America, and also by Messrs. John Marston of Wolverhampton. The tests on (2) and (3) above were carried out by Messrs. Clayton Dewandre of Lincoln. All test results are shown on attached sheets. Summary :- From attached sheets it is seen that the Gallay matrix is inferior to the Marston matrix from all points of view, while the Gallay oil cooler is inferior as regards heat dissipation and weight, but offers less resistance to oil flow than our standard type of oil cooler. No advantage would be gained therefore, by departing from our standard products. | ||
