Patent number: 8376029Abstract: A fluid flow diverter is provided in a standard rectangular header of a keel cooler for optimizing the coolant flow towards both the interior tubes and also towards the exterior tubes of the keel cooler. The improvement enhances the internal coolant flow and subsequent heat transfer efficiency similar to what has been realized with a non-rectangular header, for example, a header with a beveled wall.Type: GrantFiled: January 23, 2009Date of Patent: February 19, 2013Assignee: Duramax Marine, LLCInventors: Steven Rericha, Jeffrey S. Leeson, Michael W. Brakey

Patent number: 7481262Abstract: A keel cooler having a standard header with an internal beveled bottom wall, with orifices on the inner wall of the exterior tubes extending into the header, the orifices being in the natural flow path of the coolant flow. The orifices are sufficiently large so as not to restrict the flow of coolant. A fluid flow diverter is additionally provided in the header of the keel cooler for facilitating coolant flow towards both the interior tubes and also towards the exterior tubes.Type: GrantFiled: April 9, 2007Date of Patent: January 27, 2009Assignee: Duramax Marine, LLCInventors: Jeffrey S.

Patent number: 7328740Abstract: A multiple-pass heat exchanger having opposing headers with beveled end walls, one header having nozzles on opposite sides of a separator wall for delivering heat exchange fluid at one temperature from one or more nozzles on one side of the separator wall, the heat exchanger having one set of fluid flow tubes for conveying the fluid in one direction to the other header and another set of fluid flow tubes for carrying the fluid in the opposite direction from the latter header for delivering to the header with a nozzle or nozzles for discharging the fluid from the latter header at a changed temperature. There is also disclosed a multiple systems combined heat exchanger having an opposing headers with beveled end walls, wherein at least two heat exchangers independent of each other share the respective headers which are divided from each other by separator walls.Type: GrantFiled: May 15, 2006Date of Patent: February 12, 2008Assignee: Duramax Marine, LLCInventors: Jeffrey S. Leeson, Eric K. Peoples, Michael W. Brakey

Patent number: 4091180Abstract: A vent system for an electric storage battery having a flame arresting capability to minimize the possibility of battery explosion from ignition of explosive gases flowing from the vent plug. The vent system includes a vent plug design having an internal restricted passage and a flange extending around the top of the vent plug which cooperates with the upper surface of the battery cover to create an explosion chamber, so that in the event the explosive gases being vented are ignited, the resulting controlled explosion extinguishes the flame. One embodiment is provided wherein the top surface of the plug is flush with the top of the battery cover. A modified vent well is required for this embodiment, whereby the vent well in the battery cover has a recessed shoulder to receive the flange portion of the vent plug. A second embodiment is also provided wherein the vent plug can be used on conventional battery cover designs, but is not flush with the top of the battery cover.Type: GrantFiled: April 13, 1977Date of Patent: May 23, 1978Assignee: ESB IncorporatedInventors: Albert L. Fox, Jeffrey S. Leeson, Joseph F. Szabo

Patent number: 4072799Abstract: A vent system for an electric storage battery designed to remove the electrolyte which is entrained in the gases that are vented from the particular battery cell to the atmosphere through the vent plug assembly. The liquid gas separation feature has a primary inlet on the sidewall of the vent plug at its uppermost position that still remains in the battery cell, a drain opening in the lowermost portion of the vent plug, and baffles arranged inside the vent plug assembly such that the fluid entering the primary inlet flows in a horizontal direction and is scrubbed to remove the electrolyte. The electrolyte is then collected and returns to the cell through the drain opening while the scrubbed gases eventually reach the atmosphere. The liquid gas separation system can be used in a vent plug having a low profile for use on maintenance free batteries as well as on non-maintenance free batteries.Type: GrantFiled: April 13, 1977Date of Patent: February 7, 1978Assignee: ESB IncorporatedInventors: Jeffrey S.
