Patent number: 10088241Abstract: The present invention relates to a multi-mode thermal management assembly with a selectable coolant flow path, and in particular to an assembly that selectably removes latent and/or sensible heat. Coolant (working fluid) is routed through openings in the bottom of the thermal management assembly. The assembly can have two heat exchangers (coolers), each having side-by-side vertical paths whereby coolant both enters and exits from the heat exchangers at their respective bottoms. Plumbing is provided that can be selected to route coolant for one of the user selected cooling modes. Valves allow the user to select at least between a combination mode (latent cooling with sensible reheat) and a sensible only cooling mode. In the combination mode, the latent heat exchanger cools and dehumidifies, and the sensible heat exchanger partially reheats the air while requiring no additional work to be done on the system by external power consuming devices.Type: GrantFiled: March 15, 2013Date of Patent: October 2, 2018Assignee: Engendren CorporationInventor: Alan P.

Patent number: 6924051Abstract: Degradation of membranes in fuel cells 10 due to dehydration by relatively dry incoming reactant gases is avoided through the use of a humidifier 56,58 in the incoming reactant streams, 12,14. At least one of the humidifiers 56,58 is formed in a stack 66 having alternating flow passages 68,70 with the former receiving reactant gases and including fins 102 therein and the latter receiving hot coolant from the fuel cell 10.

Patent number: 5720337Abstract: A thermal energy storage device includes a sealed container having a wall defining a receptacle. An energy storage medium is disposed in the receptacle. The energy storage medium includes water and a gas capable of forming a gas hydrate with the water at a first transition temperature, the gas hydrate being capable of decomposing into water and the gas at a second transition temperature. Additionally, a fin extends from the wall inwardly to an inner region of the receptacle. The fin is in thermal communication with the wall, and defines a thermal energy transfer path between the wall and the inner region of the receptacle to facilitate the decomposition of the gas hydrate into water and the gas. The thermal energy storage device may also includes a mechanism positioned in the receptacle for providing mechanical movement within the thermal energy storage medium and mechanical contact between structural elements of the thermal energy storage device to facilitate the formation of the gas hydrate.Type: GrantFiled: July 30, 1996Date of Patent: February 24, 1998Assignee: Modine Manufacturing CompanyInventors: Mark G.
