WATERCRAFT WITH CLOSED LOOP COOLING
A watercraft comprising a hull, a first attachment coupled to an exterior surface of the hull, a second attachment coupled to the exterior surface of the hull, and a closed-loop cooling system. The closed-loop cooling system includes a pump, a first channel at least partially formed by the first attachment, a second channel at least partially formed by the second attachment, the second channel in fluid communication with the first channel, and a coolant circulated through the first channel and the second channel by the pump.
1 . A watercraft comprising:
a hull;
a first spray strip coupled to an exterior surface of the hull;
a second spray strip coupled to the exterior surface of the hull; and
a closed-loop cooling system including:
a pump,
a first channel at least partially formed by the first spray strip,
a second channel at least partially formed by the second spray strip, the second channel in fluid communication with the first channel, and
a coolant circulated through the first channel and the second channel by the pump.
2 . The watercraft of claim 1 , wherein the hull includes a keel, and the first spray strip is positioned to one side of the keel and the second spray strip is positioned to another side of the keel.
3 . The watercraft of claim 1 , wherein the hull defines a bow-stern length, and the first spray strip extends at least 50% of the bow-stern length.
4 . The watercraft of claim 3 , wherein the first spray strip extends at least 75% of the bow-stern length.
5 . The watercraft of claim 1 , wherein the closed-loop cooling system further includes a connection line extending between the first channel and the second channel.
6 . The watercraft of claim 1 , wherein the closed-loop cooling system further includes a first plurality of protrusions extending into the first channel and a second plurality of protrusions extending into the second channel.
7 . The watercraft of claim 6 , wherein the first plurality of protrusions extends from the hull and the second plurality of protrusions extend from the hull.
8 . The watercraft of claim 1 , wherein an inlet aperture is formed in the hull at a first end of the first spray strip and an outlet aperture is formed in the hull at a second end of the first spray strip.
9 . The watercraft of claim 1 , further including a skeg coupled to the exterior surface of the hull, and wherein the closed-loop cooling system further includes a skeg channel at least partially formed by the skeg; and wherein the coolant is circulated through the first channel, the second channel, and the skeg channel by the pump.
10 . The watercraft of claim 9 , wherein the closed-loop cooling system further includes a radiator coupled to the hull, and wherein the coolant is circulated through the first channel, the second channel, the skeg channel, and the radiator by the pump.
11 . The watercraft of claim 1 , further including an electric drive and a battery electrically coupled to the electric drive; wherein the closed-loop cooling system is configured to cool the electric drive, the battery, or a combination thereof.
12 . The watercraft of claim 1 , wherein the coolant includes ethylene glycol and deionized water.
13 . A watercraft comprising:
a hull;
a skeg coupled to an exterior surface of the hull; and
a closed-loop cooling system including:
a pump,
a first channel at least partially formed by the skeg, and
a coolant circulated through the first channel by the pump.
14 . The watercraft of claim 13 , wherein the first channel extends between an inlet formed in the skeg and an outlet formed in the skeg.
15 . The watercraft of claim 14 , wherein the first channel is serpentine.
16 . The watercraft of claim 14 , further including a plurality of parallel channels extending between an upstream portion of the first channel and a downstream portion of the first channel.
17 . The watercraft of claim 13 , further including a spray strip coupled to an exterior surface of the hull, and wherein the closed-loop cooling system further includes a second channel at least partially formed by the spray strip; wherein the coolant is circulated through the first channel and the second channel by the pump.
18 . The watercraft of claim 17 , wherein the closed-loop cooling system further includes a radiator including a shell coupled to the bull; and wherein the coolant is circulated through the first channel, the second channel, and the radiator by the pump.
19 . The watercraft of claim 13 , further including an electric drive and a battery electrically coupled to the electric drive; wherein the closed-loop cooling system is configured to cool the electric drive, the battery, or a combination thereof.
20 . The watercraft of claim 13 , wherein the coolant includes ethylene glycol and deionized water.
