Abstract

A cooling device for cooling a heat generating component, wherein the cooling device comprises a heat sink and at least one heat pipe that is in thermal contact with the heat sink, wherein the at least one heat pipe comprises a thermal contact area that is configured for thermal contact with a heat generating component, and the at least one heat pipe is configured in a shape that provides mechanical spring properties. Such a heat generating component may comprise a pluggable module. Also disclosed is a receptacle assembly comprising a frame having an interior cavity configured for accommodating a heat generating component and having an opening for receiving the heat generating component, characterized in that it comprises a cooling device. Disclosed is also a system comprising a receptacle assembly, and a printed board assembly (PBA) comprising a receptacle assembly.

Claims (15)

1. A cooling device for cooling a heat generating component, wherein the cooling device comprises a heat sink and a heat pipe that is in thermal contact with the heat sink, wherein the heat pipe comprises a first portion having a thermal contact area that is in thermal contact with the heat generating component, a second portion that is in thermal contact with the heat sink, and a third portion that is disposed to reside between ends of the second portion and connected to the first portion, and the third portion to reside between the first portion and the second portion, and wherein the heat pipe is made of flexible material and configured in a shape that provides elastic energy storage properties and without use of a mechanical assisting device between the heat pipe and the heat sink.

2. The cooling device according to claim 1 , wherein the heat generating component comprises a pluggable module.

3. The cooling device according to claim 1 , wherein the third portion comprises at least a part that forms an acute angle or an obtuse angle to at least one of the first portion and the second portion, and thereby achieving mechanical spring properties.

4. The cooling device according to claim 1 , wherein the second portion comprises a first end portion and a second end portion that are in thermal contact with the heat sink, wherein the third portion comprises a first connecting portion that connects the first end portion of the second portion with the first portion and a second connecting portion that connects the second end portion of the second portion with the first portion, and wherein respective first and second connecting portion comprise at least a part that form an acute angle or an obtuse angle in relation to the first end portion and the second end portion.

5. The cooling device according to claim 1 , wherein the third portion connects the first portion to the second portion diagonally that forms an acute angle or an obtuse angle in relation to the second portion.

6. The cooling device according to claim 1 , wherein the heat pipe is a flat heat pipe.

7. A receptacle assembly comprising a frame having an interior cavity configured for accommodating a heat generating component and having an opening for receiving the heat generating component, the receptacle assembly further comprises a cooling device, wherein the cooling device is for cooling the heat generating component, in which the cooling device comprises a heat sink and a heat pipe that is in thermal contact with the heat sink, wherein the heat pipe comprises a first portion having a thermal contact area that is in thermal contact with the heat generating component, a second portion that is in thermal contact with the heat sink, and a third portion that is disposed to reside between ends of the second portion and connected to the first portion, and the third portion to reside between the first portion and the second portion, and wherein the heat pipe is made of flexible material and configured in a shape that provides elastic energy storage properties and without use of a mechanical assisting device between the heat pipe and the heat sink.

8. The receptacle assembly according to claim 7 , wherein the heat pipe is configured to exert a biasing force on the frame.

9. The receptacle assembly according to claim 7 , wherein the heat pipe is configured to exert a biasing force on the heat generating component during insertion into the interior cavity of the frame and to become resiliently deformed when the heat generating component is inserted into the interior cavity of the frame.

10. The receptacle assembly according to claim 7 , wherein the heat pipe is configured to be in thermal contact with the heat generating component via a heat transfer element of the frame, directly with the heat generating component, or both via the heat transfer element and directly with the heat generating component.

11. The receptacle assembly according to claim 10 , wherein the frame comprises a thermally conductive element supported in the frame and forming the heat transfer element of the frame and which the thermally conductive element is configured to be in thermal contact with the heat generating component accommodated in the interior cavity of the frame.

12. The receptacle assembly according to claim 10 , wherein the frame comprises a top opening facing towards the heat sink, wherein the heat pipe penetrates into the interior cavity of the frame via the top opening and is configured to enter into thermal contact with the heat generating component when the heat generating component is accommodated in the interior cavity.

13. The receptacle assembly in accordance with claim 7 disposed as part of a system, which system includes the heat generating component that is insertable into the interior cavity of the frame.

14. The receptacle assembly according to claim 13 , wherein the heat generating component is a pluggable module.

15. The receptacle assembly in accordance with claim 7 disposed on a printed board assembly.
