Modular liquid cooled burn in system
View Patent ↗An electronic device burn-in thermal management system includes Burn-in-Boards (BIBs) with quick disconnect connectors to easily connect and disconnect the BIB ( 102 ) from liquid cooling lines ( 104, 106 ) in a rack that can hold one or more BIBs. The BIB ( 102 ) may include liquid cooled heat sinks ( 408 ) embedded in the BIB sockets ( 406 ) in order to cool the electronic devices undergoing burn-in test (DUT). This arrangement allows the DUT to make positive thermal contact with the heat sink when it is mounted in the BIB socket and allows the user to remove the BIB ( 102 ) quickly after completing a test to load the next batch of DUTs onto a separate BIB.
1. A burn-in board, comprising:
an electrical socket for receiving an electrical component;
a liquid cooled heat sink chamber located in thermal proximity to the electrical socket;
an input liquid supply line coupled to a first quick disconnect connector;
an output liquid supply line coupled to a second quick disconnect connector;
the input and output supply lines coupled to the liquid cooled heat sink chamber in order to supply liquid to the liquid cooled heat sink chamber; and
a flip top coupled to the electrical socket and the liquid cooled heat sink chamber is located on the flip top, the flip top including a hinge for allowing the flip top to move into a closed position over the electrical socket.
2. A burn-in board as defined in claim 1 , wherein the liquid cooled heat sink chamber includes a thermal transfer top which is in thermal contact with the electrical outlet.
3. A burn-in board as defined in claim 2 , further comprising a liquid chamber cavity that receives cooling liquid from the input liquid supply line.
4. A burn-in board as defined in claim 3 , wherein the liquid cooled heat sink chamber includes an input coupled to the input liquid supply line for receiving cooling liquid and an output coupled to the output liquid supply line for removing liquid from the liquid chamber cavity.
5. A burn-in board as defined in claim 1 , wherein the first quick disconnect connector is part of a connector that also includes one or more electrical connections.
6. A burn-in board as defined in claim 1 , wherein the liquid cooled heat sink chamber comes into thermal contact with the electrical component when the flip top is closed over the electrical socket.
7. A burn-in board as defined in claim 6 , further comprising a second liquid cooled heat sink located underneath the electrical socket.
8. A burn-in board as defined in claim 7 , wherein the second liquid cooled heat sink is coupled to the input and output liquid supply lines.
9. A burn-in board as defined in claim 1 , wherein the input and output supply lines comprise flexible fluid lines.
10. A liquid cooled socket, comprising
a socket having electrical connections for receiving an electrical component;
a liquid cooled heat sink chamber located in thermal proximity to the electrical socket;
input and output liquid supply lines coupled to the liquid cooled heat sink chamber;
a flip top coupled to the socket including a hinged section; and
the liquid cooled heat sink chamber is located on the flip top hinged section such that when the flip top is closed over the socket, the liquid cooled heat sink chamber comes into thermal contact with the electrical component.
11. A liquid cooled socket as defined in claim 10 , wherein the input and output liquid supply lines are each coupled to quick disconnect connectors.
12. A liquid cooled socket as defined in claim 10 , further comprising:
a second liquid cooled heat sink chamber located on the flip top and underneath the socket.
13. A liquid cooled socket as defined in claim 10 , wherein the socket is located on a burn in board.
14. A liquid cooled socket as defined in claim 10 , wherein the liquid cooled heat sink chamber includes a heat transfer top that is contact with the socket.
15. A liquid cooled socket as defined in claim 10 , wherein the liquid cooled heat sink chamber makes thermal contact with one or more pins located on the electrical component.
