Abstract
A liquid cold plate heat exchanger includes a heat sink with a plurality of fins received in a cavity between a base plate and a cap. A spring plate may be positioned between a top surface of the heat sink, e.g., over fins of the heat sink, and a lower surface of the cap in the cavity. The spring plate may at least partially and/or completely fill a gap between the heat sink and the cap, aiding in thermal conduction between the cap and heat sink.
Claims20
A liquid cold plate heat exchanger, comprising:
- a base having an upper surface;
- a heat sink having a plurality of fins arranged on the upper surface of the base, the plurality of fins defining a top surface of the heat sink;
- a cap having a lower surface positioned over the upper surface of the base and the heat sink;
- and
- a spring plate positioned between the top surface of the heat sink and the lower surface of the cap,
- wherein with the cap secured to the base, the spring plate is arranged to exert an upward bias on the lower surface of the cap and a downward bias on the top surface of the heat sink.
The liquid cold plate heat exchanger of claim 7, wherein the spring plate is formed of a bent metal sheet that forms the heat sink contacting portion and the first and second cap contacting portions, and wherein the heat sink contacting portion is located in a lower plane positioned below an upper plane in which the first and second cap contacting portions are located.
A liquid cold plate heat exchanger, comprising:
- a base having an upper surface;
- a heat sink having a plurality of fins arranged on the upper surface of the base, the plurality of fins defining a top surface of the heat sink;
- a cap having a lower surface and a cavity formed in a portion of the lower surface, the cavity positioned over the upper surface of the base and the heat sink;
- and
- a spring plate positioned between the top surface of the heat sink and the lower surface of the cap at the cavity,
- wherein a portion of the lower surface of the cap around the cavity is secured to a portion of the upper surface of the base around the heat sink, and the spring plate is arranged to exert an upward bias on the lower surface of the cap at the cavity and a downward bias on the top surface of the heat sink.
