Abstract
A jet pump housing is mountable to a hull of a personal watercraft. The jet pump housing comprises a body extending between an inlet and an outlet. The body has an inner wall delimiting an interior of the body and an outer wall. The inner wall and the outer wall are configured to be exposed to water during use of the personal watercraft. The body is shaped and sized to allow water to flow into the interior via the inlet and to expel water from the outlet. The body has one or more fluid passages positioned between the inner wall and the outer wall. The one or more fluid passages are fluidly isolated from the water and are in heat exchange relationship with the water via one or both of the inner wall and the outer wall.
Claims20
A personal watercraft, comprising:
- a jet propulsion system, including:
- a jet pump housing extending between an inlet of the jet pump housing and an outlet of the jet pump housing, the jet pump housing having an inner wall delimiting an interior of the jet pump housing and an outer wall, the inner wall and the outer wall configured to be exposed to water during use of the personal watercraft, the jet pump housing having one or more fluid passages positioned between the inner wall and the outer wall, the one or more fluid passages fluidly isolated from the water and in heat exchange relationship with the water via one or both of the inner wall and the outer wall;
- and
- an impeller positioned within the interior of the jet pump housing and rotatable about an impeller axis to draw the water into the interior of the jet pump housing via the inlet and to expel water from the outlet;
- and
- a thermal management system having a pump and fluid lines extending between the pump and the one or more fluid passages of the jet pump housing, the pump operable to convey a thermal transfer fluid through the fluid lines to one or more components of the personal watercraft to absorb heat from the one or more components, the pump operable to convey the thermal transfer fluid through the fluid lines to the one or more fluid passages of the jet pump housing to release the heat to the water.
A jet pump housing mountable to a hull of a personal watercraft, the jet pump housing comprising:
- a body extending between an inlet of the jet pump housing and an outlet of the jet pump housing, the body having an inner wall delimiting an interior of the body and an outer wall, the inner wall and the outer wall configured to be exposed to water during use of the personal watercraft, the body shaped and sized to house an impeller of a jet pump in the interior of the body and allow water to flow into the interior via the inlet and to expel water from the outlet, the body having one or more fluid passages positioned between the inner wall and the outer wall, the one or more fluid passages fluidly isolated from the water and in heat exchange relationship with the water via one or both of the inner wall and the outer wall.
A personal watercraft, comprising:
- a hull defining a water intake extending along a bottom portion of the hull, the water intake defining an opening covered by a grate;
- a ride plate positioned along the bottom portion of the hull;
- a pump shoe extending between the grate and the ride plate;
- one or more fluid passages positioned in one or both of the grate and the pump shoe;
- and
- a thermal management system having a pump and fluid lines extending between the pump and the one or more fluid passages, the pump operable to convey a thermal transfer fluid through the fluid lines to one or more components of the personal watercraft to absorb heat from the one or more components, the pump operable to convey the thermal transfer fluid through the fluid lines to the one or more fluid passages to release the heat to the water.
