Thermal connector for printed circuit card equipped with electronic components
First Claim
1. A thermal connector for a printed circuit card equipped with at least one electronic component, said card comprising a heat-conducting substrate, said connector being adapted to be mounted with similar connectors ina frame which receives a plurality of said cards, said connector comprising:
- an elongated unitary block having a major axis and an upper surface including a slot extending along said axis and adapted to receive said heat-conducting substrate of said card, said slot including a vertically extending wall formed of a material which is a good heat conductor;
spring means mounted in said block adjacent to said slot and including a spring adapted to urge said heat-conducting substrate into direct contact with said wall when said card is inserted in said slot;
an internal duct extending along said axis and located beneath said slot, said duct being adapted to receive and circulate a heat-carrying fluid to serve as a heat exchanger for said card;
an entry channel extending into said block from and communicating with said duct for introducing said heat-carrying fluid into said duct; and
an evacuation channel extending into said block and communicating with said duct for evacuating said heat-carrying fluid from said duct.

Abstract
The present invention relates to a thermal connector for printed circuit card mounted with at least one electronic component, the card having a heat-conducting substrate. The connector has at least one wall made of a material which is a good heat conductor in direct contact with a part of the heat-conducting substrate and a means forming a heat sink integral with the wall.
The invention applies in particular to electronic cabinets comprising a large number of cards.
