| 20120107663 | Heat Exchanger and Battery Unit Structure for Cooling Thermally Conductive Batteries - A heat exchanger and battery unit structure is provided for cooling battery units (or cells) where the thermally conductive nature of the battery forms a cooling path. The heat exchanger is in the form of a cooling element provided with an engaging device formed on or attached to an outer surface of the cooling plate for receiving and/or engaging with a corresponding engaging portion on a battery unit (or cell). The interconnection between the battery unit (or cell) and heat exchanger creates a mechanical interlock between the two components that results in improved heat transfer properties between the two components. | 05-03-2012 |
| 20120061062 | HEAT EXCHANGER WITH MANIFOLD STRENGTHENING PROTRUSION - A plate type heat exchanger having a plurality of stacked plate pairs made up of first and second plates. Each plate pair has opposed manifold members that form respective inlet and outlet manifolds for the flow of a first fluid through a first set of fluid channels formed by the plate pairs. The manifold members space the plate pairs apart to form a second set of transverse flow channels for the flow of a second fluid. A protrusion member is formed at an end portion of the plates and proximal to each of the manifold members and has a mating surface, such that the protrusion members on the second plate of one plate pair align and abut with the protrusion members on the first plate of an adjacent plate pair thereby reinforcing and strengthening the manifold region of the heat exchanger to prevent deformation of the manifold under pressure. | 03-15-2012 |

A relief valve is mounted in the chamber and has a relief valve member movable between closed and open positions in order to close or open pressure relief ports. This relief valve member is biased towards the closed position. Excessive pressure build up in an end section of the chamber causes the relief valve member to move to its open position. | 05-27-2010 |
