摘要:
A cooling apparatus for cooling a fluid by means of surface water, the cooling apparatus comprising more than one tubes for containing and transporting the fluid in its interior, the exterior of the tube being in operation at least partially submerged in the surface water so as to cool the tube to thereby also cool the fluid, at least one light source for producing light that hinders fouling on at least part of the submerged exterior and at least one optic unit for enhancing the distribution of anti-fouling light on the submerged exterior. By this structure anti-fouling of the cooling apparatus can be assured in an effective manner.

An intelligent sea water cooling system including a first fluid cooling loop coupled to a heat exchanger, a second fluid cooling loop coupled to the heat exchanger and including a fluid pump for circulating fluid through the second fluid cooling loop, and a controller operatively connected to the fluid pump. The controller may be configured to monitor an actual temperature in the first fluid cooling loop and to adjust a speed of the fluid pump based on the monitored temperature in order to achieve a desired temperature in the first fluid cooling loop.

The boat engine cooling system provides cooling of the engine of a boat or other nautical vehicle through both chemical coolant, such as an antifreeze solution, and environmental water; i.e., the water the vehicle is passing through. In use, heated engine coolant is expelled by the engine and passes through a coolant inlet port formed through a hollow tank, where it is transported through a coolant pipe to the engine. Further, water from the environment (i.e., the lake, ocean or other body of water the vehicle is passing through) is injected into a cooling reservoir in the hollow tank through a water inlet port. The engine coolant passing through a central portion of the coolant pipe is cooled by the water in the cooling reservoir prior to circulating back through the engine.

A cooling system for a marine propulsion device incorporates both a closed portion and an open portion. The closed portion is operated to encourage nucleate boiling and is provided with a pump and a valve in order to regulate the rate of flow of coolant through certain heat emitting regions of the engine. The pump can be an electric variable speed pump and the valve can be used to direct coolant through a heat exchanger or to bypass the coolant around the heat exchanger.

A personal watercraft is disclosed with a hull, a seating assembly, and a four stroke internal combustion engine below the seating assembly. The engine has at least one intake valve for each of the combustion cylinder chambers, at least one exhaust valve for each of the combustion cylinder chambers, and a valve actuation assembly located in a cylinder head for operating the intake and exhaust valves. At least one air intake passageway is operatively coupled to the combustion cylinder chambers through the intake valves. An air intake manifold is connected to the cylinder bead and operatively connected to the at least one air intake passageway. The engine also has a supercharger for boosting air to the air intake manifold. The watercraft also includes a propulsion unit, operatively coupled to the crankshaft, which is located on one end of the two ends of the crankcase.

An air passage and a cooling water passage can be formed in an intercooler provided on a small planing boat. A cooling water inlet of a cooling water passage in the intercooler can be provided at the lower end of the intercooler. A cooling water outlet can be at the upper end of the intercooler. The intercooler can be vertically elongated and disposed at the front side of the engine. Further, a discharge port of a supercharger can be directed upwardly and an air inlet of the intercooler can be provided on the intercooler at the upper part. Furthermore, the intercooler, the supercharger and an intake manifold can be arranged such that when viewed in the lateral direction, the intercooler and supercharger overlap each other and when viewed in the longitudinal direction, the intercooler and intake manifold can also overlap each other. Moreover, the intercooler can be of a two-pass type.
摘要:
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.
摘要:
A heater and method for delivering heat energy from a water cooled two cycle marine engine is described and which includes an exhaust expansion chamber operably coupled with a two cycle marine engine, and wherein the two cycle marine engine produces a source of heated water; a heater coupled in fluid flowing relation relative to the exhaust expansion chamber, and which receives the source of heated water; and a flow restrictor coupled in fluid flowing relation relative to both the heater and the exhaust expansion chamber, and which delays the delivery of the heated water from the exhaust expansion chamber to the heater to increase the temperature of the heated water.
