Benefits of technology

The patent describes an evaporative cooler circulation and drain system that can be used in vehicles. The system includes a tank with a drain opening and a valve that can be opened or closed to control the flow of fluid. The system can be used in a circulation mode or a drain-circulation mode. In the circulation mode, fluid is continuously circulated within the tank, while in the drain-circulation mode, fluid is circulated and drained from the tank. The system may also include a UV light and a filter to clean the fluid. The patent also mentions an electronic controller that can control the pumps and valves to implement the circulation and drain modes. The technical effects of the patent are a more efficient and effective evaporative cooling system that can be used in a variety of vehicles and applications.

Problems solved by technology

However, evaporative coolers are subject to being plagued with mineral scale fouling, biological growth and corrosion of metal surfaces.
Where minimal head pressure exists as water drains from a shallow tank into a drain pipe having a minimal slope, a low flow rate can exist which increases the likelihood of plugging in the drain piping.
Such minimal drain flow rate also reduces effectiveness in draining debris and minerals from the tank.

first embodiment

[0045]Referring to FIGS. 1 and 2, the circulation and drain system 10 is presented. As shown, the circulation and drain system 10 includes an evaporator tank 14 having a sidewall 15 and a bottom side 17 that together define an interior volume 11 for holding a fluid 12, such as water. The sidewall 15 may have various cross-sectional shapes as dictated by the requirements of the evaporator, for example square, rectangular, and circular cross-sectional shapes. The bottom side 17 may also be provided with various shapes to accommodate the perimeter defined by the sidewall 15.

[0046]The evaporator tank 14 may be provided with a drain opening 16 located in one of the bottom side 17 and the sidewall 15. In the particular embodiment shown, the drain opening 16 is provided at the bottom side 17 of the tank 14 and is connected to a drain pipe section 110.

[0047]In one aspect, a drain valve 30 having an inlet port 32 and an outlet port 34 is provided. As shown, the inlet port 32 is connected to ...

fifth embodiment

[0062]In operation, the fluid pump 80 directs fluid 12 between the inlet 82 and first outlet 84 when rotated in a first direction and directs fluid 12 between the inlet 82 and the second outlet 86 when rotated in a second direction. As shown, the drain and circulation system 10 is operable between a circulation mode and a drain mode. In the circulation mode, the fluid pump 80 is rotated in the second direction such that fluid 12 is continuously circulated within the interior volume 11 of the storage tank 14. In the drain mode, the fluid pump 80 is rotated in the first direction such that fluid 12 is drained from the interior volume 11 of the tank 14. Where a drain-circulation mode is desired, the discharge pipe section 104 can be reconfigured, for example by orienting the discharge pipe section outlet 104a within the interior volume 11 of the storage tank 14, as shown at FIGS. 1-2.

[0063]Referring to FIGS. 11-12, a sixth embodiment of the drain and circulation system 10 is shown. To ...

sixth embodiment

[0064]the circulation and drain system 10 is different from previous embodiments in that two fluid pumps are provided in a first fluid pump 20 and a second fluid pump 60, and in that no drain valve 30 is provided. The first fluid pump 20 is configured such that the discharge pipe section 104 is directly connected to drain pipe section 114 such that in order to drain the tank 14, the first fluid pump 20 must be activated. The second fluid pump 60 has an outlet 64 connected to the discharge pipe section 106 and has an inlet 62 that is in fluid communication with the interior volume 11 of the storage tank 14. Accordingly, fluid 12 can only be circulated within the tank 14 by operation of the second fluid pump 60 via inlet 62, discharge pipe sections 106, 108 and ultraviolet light 40.

[0065]As configured, the sixth embodiment of the circulation and drain system 10 has a circulation mode, a drain mode, and a drain-circulation mode. In the circulation mode, the first fluid pump 20 is deact...

Abstract

An evaporative cooler circulation and drain system including a fluid pump and a storage tank defining an interior volume for holding a fluid is disclosed. In one aspect, the system is operable between a circulation and drain-circulation operational modes. In the circulation mode, a drain valve is closed and the fluid pump is activated such that fluid is continuously circulated within the storage tank to discourage debris from settling by keeping debris in the tank in suspension. In the drain-circulation mode, the drain valve is opened and the fluid pump is activated such that fluid is both being continuously circulated within the interior volume of the storage tank and draining from the tank. In some embodiments, the system increases the drain flow rate by directing circulated fluid directly at a drain opening of the tank to flush debris through the drain piping and prevent plugging.
