Heat transfer cold plate arrangement
First Claim
1. A heat transfer cold plate arrangement comprising:
- a metallic cold plate provided with coolant passages for circulating a coolant;
an inlet/outlet header made of electrically insulating material affixed to one end of the metallic cold plate to supply coolant through an inlet nozzle to a first set of coolant passages in the cold plate and to receive coolant from a second set of coolant passages in the cold plate for transfer to an outlet nozzle;
a return header made of electrically insulating material affixed to an opposite end of the cold plate providing communication between the first and second set of coolant passages;
the headers and the ends of the cold plate being joined by projections received in recesses; and
mounting means on at least one of the headers whereby the cold plate is supported in an electrically insulating manner.

Abstract
In the embodiments described in the specification a metal heat transfer cold plate has two sets of parallel coolant passages extending between opposite end surfaces and non-metallic headers made of electrically insulating material are attached to the opposite ends of the metal plate. One of the headers provides an inlet to one set of coolant passages and an outlet from the other set of coolant passages and the other header provides fluid communication between the two sets of coolant passages. The headers are affixed to the cold plate by adhesive or by a snap-in connection having a sealing gasket between each header and the cold plate and the assembled cold plate and headers are insulatively supported by mounting feet attached to the electrically insulating headers.
