Passive by-pass for heat exchangers
First Claim
1. A heat exchanger comprising:
- a housing defining a fluid inlet chamber and a fluid outlet chamber;
means defining a plurality of heat exchange passages located between and communicating with the inlet and outlet chambers, the heat exchange passages having inlet passages defining an inlet flow manifold communicating with the inlet chamber;
a separator located adjacent to the inlet flow manifold; and
said separator defining a calibrated bypass orifice therethrough located remote from the inlet passages and communicating with the inlet flow manifold for the continuous flow out of the inlet flow manifold of a portion only of the fluid entering the inlet flow manifold.

Abstract
A heat exchanger is disclosed for automotive lubricants and coolants wherein the heat exchanger has a calibrated bypass orifice located therein to maintain the flow therethrough at all times, particularly during cold flow operation, or high pressure transient conditions such as at engine start-up. The heat exchanger has a housing defining a fluid inlet chamber and a fluid outlet chamber. A separator is located between the inlet and outlet chambers and heat exchange passages are located between and communicate with the inlet and outlet chambers. The separator has a calibrated bypass orifice therethrough for the continuous flow of fluid between the inlet and outlet chambers bypassing the heat exchange passages.
