AI Technical Summary

Technical Problem

Current cooling systems, both active and passive, are complex, expensive, and limited in orientation due to the need for external piping and connectors, and passive systems cannot be oriented arbitrarily relative to the gravity vector.

Method used

A highly integrated heat sink with an integrated coolant pump, utilizing capillary forces and rotating discs to circulate fluid, eliminating the need for external components and allowing orientation in any direction.

Benefits of technology

Provides a closed system with reduced complexity, improved cooling performance, and wider installation possibilities by integrating the pump within the heat sink, enhancing heat dissipation efficiency and reducing maintenance.

Abstract

The disclosure relates to a heatsink (100), comprising a heatsink body (110) made of a heat-conducting material. The heatsink body (110) comprises a base plate (111) attachable to a heat source for receiving heat from the heat source; and a heat dissipation area (114). The heatsink body (110) comprises one or more interconnected fluid channels (112) which are closed to an external ambient. The fluid channels (112) are integrated within the heatsink body (110) between the base plate (111) and the heat dissipation area (114). The fluid channels (112) are filled with a coolant (113). The heatsink (100) comprises one or more coolant pumps (120) integrated within the heatsink body (110). The one or more coolant pumps (120) are configured to circulate (121a, 121b) the coolant (113) through the one or more fluid channels (112) to transport heat from the heat source received by the base plate (111) to the heat dissipation area (114) for dissipation to the external ambient.
