Flexible Tube Connection for Thermoelectric Solutions for Cooling Multiple Adjacent Processors

Disclosed is a method that uses a flexible wicked or wickless tube connected to two or more vapor chambers (VC) to cool two or more adjacent processors. Benefits include an improved cooling capability and lower thermoelectric (TEC) power consumption.

Background

The following are current strategies for cooling processors:

§         TEC+VC. This solution has no connecting tube and is limited by the VC footprint area, and therefore has a limited COP.

§         Closed Pumped Liquid cooling. This solution uses a water pump which is susceptible to leaking and freezing. In addition, the system requires a remote volume for the heat exchanger.

§         Vapor Compression system. This solution is costly and often unreliable. In addition, it requires a remote volume for the condenser.

General Description

The disclosed method uses a flexible tube connected to two or more vapor chambers (VC) to cool two or more adjacent processors. The tube ensures that the vapor operating temperature is almost the same in both VC. The liquid and vapor are freely circulated through the flexible tube in both directions. The tube may have a wick or be wickless, depending on the orientation of the VCs with respect to gravity.

Figure 1 shows two separate cooling solutions connected by a flexible tube. Each cooling solution is composed of the following: a VC in thermal contact with the heat source, thermoelectric modules attached to the condenser part of the vapor chamber, and thin base fins attached to the thermoelectric modules. The VC’s function is to sprea...
