METHOD OF MANUFACTURING BRAZED ALUMINUM PLATE AND RING HEAT EXCHANGER

摘要

A plate and ring type heat exchanger (10) and method of manufacture thereof whereby the manifolds are built simultaneously with the cor to obviate the need of welding the manifolds onto the core after furnace brazing. Spacer elements (30) having a pair of spacer parts locateD at the fist and second manifolds (14A, 14B) and a pair of straight lengths extending along the core between the manifold spacer parts may be made in any length to allow for quick and easy changeover between the building of different width cores.
