Abstract
The invention relates to an apparatus for cooling and maintaining the water temperature in the live wells of fishing vessels. This twelve volt singular device is applied through the live well wall, and through use of thermoelectric technology the ambient water temperature within the live well is decreased. The importance of cooler water is that holds more oxygen and lowers metabolism in fish, which in turn increases the survival rate of captive fish. This invention is targeted for use by sports fisherman for use in tournaments to avoid penalties for dead fish and to promote the conservation of fish for ecological purposes.
Description
- The invention relates to increasing the survival rate of fish in live wells by maintaining a healthy water temperature; via an apparatus that decreases water temperatures when applied to a fishing vessel's live well. It is widely known, within the fishing industry, that high water temperatures are the leading cause of fish death in live wells. As water sits in a live well, even if it's circulated, the temperature increases which makes it almost impossible to hold oxygen. There are various options available to assist with live well oxygenation and circulation, but this simple one-piece device decreases the water temperature, which in turn increases the oxygenation.
- U.S. Pat. No. 7,134,293 to Rabal discloses a cooling and aerating live well system in the form of a device that pumps water out of the live well into a separate cooling chamber, where a thermoelectric device cools the water, and then pumps it back into the live well. It is evident that this system is poorly designed for use in a boat due to its size, complexity, and energy requirements.
- This invention is a device that, once installed in the live well of a fishing vessel, functions to slightly decrease and maintain the current water temperature that is held in the live well. The device is comprised of several components which include a cooling probe, which is cooled through thermoelectric technology. The thermoelectric device transfers heat from the probe to the cooling fins which are located on the back of the device. A twelve volt powered water resistant fan is mounted directly to the back of the unit to assist in cooling the device. The advantages of this invention over the prior art include: its' compact size and simple complexity, which allows for easy installment and use; its' one piece construction is highly energy efficient; it cools the water within the live well without actually removing the water for cooling, which eliminates the extra attached equipment such as pumps, hoses, and controlling devices.
- It is the object of this invention to lower water temperatures in live wells to decrease mortality rates of fish during fishing tournaments to avoid penalties.
- It is another object of this invention to decrease water temperatures in live wells to promote fish conservation for ecological reasons.

FIG. 1 is a side view with portions removed (to simplify the figure) of the cooling apparatus under operating circumstances. -
FIG. 2 is an exploded view of a portion of the cooling apparatus shown inFIG. 1 with some components omitted to simplify the figure. - Referring to
FIG. 1 , anapparatus 10 according to the invention is shown. Awall 12 of alive well 14 has theapparatus 10 incorporated through it. Theapparatus 10 is designed to be used through thewall 12 because direct contact between theapparatus 10 and thewater 16 is pertinent for cooling. Theapparatus 10 has acold sink 18 for producing a reduced temperature to cool thewater 16. Thecold sink 18 has aprobe 20 made of a highly thermally conductive material such as aluminum, copper, and stainless steel. - As shown in
FIG. 2 , theprobe 20 has a threadedportion 22 and abase 24. Thebase 24 is shaped to connect fully with athermoelectric device 26. Preferably, thebase 24 and thethermoelectric device 26 are significantly identical to minimize energy loss. Thethermoelectric device 26 is a commercially available device which produces a reduced temperature on one side and an increased temperature on the other side when a direct voltage is applied to the device. - The
thermoelectric device 26 is arranged so that inFIG. 1 cold side is facing thewater 16 and hot side is facing aheat sink 32. Theheat sink 32 engages thethermoelectric device 26 fully so that heat produced by the thermoelectric device can be removed efficiently and effectively. It is imperative to achieve firm contact between thethermoelectric device 26 and both thecold sink 18 and theheat sink 32 to prevent water leakage. A feature of the invention which prevents potential leakage is the compression of thethermoelectric device 26 between theheat sink 32 and thecold sink 18 by the connectingtabs 34. The connectingtabs 34, which are located on thebase 24, are bolted to theheat sink 32. - An electrically non-conductive, thermally insulating
body 36 has a cut-out 38 to allow it to be positioned so that one flat surface contacts thebase 24 so that the contact between thebase 24 and thethermoelectric device 26 is insulated against external temperature influences. In addition, theinsulating body 36 provides a relatively soft surface for contact with the outside surface of thewall 12. - The
probe 20 extends through a hole in thewall 12 into thewater 16 and is maintained in its position by anut 40 which screws onto the threadedportion 22 and has awasher 42 pressing against the outside surface of thewall 12. Thewasher 42 can be made of silicone, PVC or some other suitable material and seals the hole in thewall 12 against leakage. - It is preferable to position the
washer 42 on the outside surface of thewall 12 to form a reliable seal against leakage rather than positioning thewasher 42 on the inside surface because the threadedportion 22 would not interact with thewasher 42 to distort it into a shape forming a satisfactory seal. Thewasher 42 has a shape in which the surface against thebase 24 is substantially flat, while the surface abutting against thewall 12 is slightly curved so that pressure during the tightening of thenut 40 distorts thewasher 42 to form a very reliable seal. - The
heat sink 32 is a conventional thermally conductive material withfins 44 for dissipating heat. A commercially available waterresistant fan 46 is arranged behind theheat sink 32. Thewires 48 are for the input of twelve volt electrical power into the waterresistant fan 46. The waterresistant fan 46 blows air to cool thefins 44 because the cooling of thethermoelectric device 26 is diminished if the hot side is too hot. Theheat sink 32 is matched to the waterresistant fan 46 to maximize the heat transfer away from thethermoelectric device 26. The waterresistant fan 46 andthermoelectric device 26 are connected to a twelvevolt power supply 50.
