Abstract
A heat management system is provided for an automotive system having a plurality of heat manageable components. The heat management system includes a plurality of heat transferring path having a plurality of heat pipes, and a heat exchanger for each of the heat manageable component of the automotive system. The heat pipes are configured to transfer heat from at least one of the heat exchanger to another heat exchanger.
Claims17
A heat management system for an automotive system having a plurality of heat manageable components, the heat management system comprising:
- a common manifold;
- a plurality of heat exchangers, including a heat exchanger for each of the plurality of heat manageable components of the automotive system;
- a plurality of heat pipes, including a respective heat pipe extending between the common manifold and each of the plurality of heat exchangers;
- a plurality of valves, including a respective valve positioned along each of the plurality of heat pipes;
- wherein each of the plurality of heat pipes is configured to selectively transfer heat from a first heat exchanger of the plurality of heat exchangers to a second heat exchanger of the plurality of heat exchangers based on actuation of the plurality of valves,
- wherein each of the plurality of heat pipes is formed by a heat-transfer device comprising a metal casing, a vapor cavity surrounded by the metal casing, and a wick structure in between the metal casing and the vapor cavity, the heat-transfer device having closed first and second ends and containing a working fluid formed by liquid and vapor such that, upon opening of the respective valve, heat at the first end evaporates the working fluid to absorb thermal energy and migrates the vapor along the vapor cavity to the second end whereupon the vapor condenses to release the thermal energy and the liquid is absorbed into the wick structure to flow back to the first end.
