Abstract
The present invention relates to the field of automotive heat exchanger assemblies, and, in particular, block and manifold assemblies. The present invention also relates to a method of making a positive leak path to determine leaks prior to commercial employment of heat exchanger assemblies. The present invention further relates to a method of determining whether or not a leak seal is properly brazed by providing a positive leak path at the point of assembly or joint of a block and manifold.
Claims12
A heat exchanger assembly which detects temporary seals comprising:
- a block;
- a manifold;
- and
- a means for detecting temporary seals between the block and the manifold.
A method for detecting temporary seals in heat exchanger assemblies comprising:
- providing a means for allowing fluid passage between a manifold and a block via a hole;
- passing a brazing fluid through said passage;
- providing a positive leak path comprising a means for detecting temporary seals in the connecting block manifold or insert of the heat exchanger assembly;
- testing for positive leaks.
