Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic automatic transmissions, and in particular relates to an amphibious heat dissipation device and an amphibious power system for a transmission. Background Art

[0002] Currently, amphibious power platforms can reach speeds exceeding 45 km / h in water and over 100 km / h on land, both reaching high-speed ranges.

If two or more engines are used, the cooling system may suffer from insufficient fan power, leading to high temperatures when operating at full power underwater. Some manufacturers use external cooling tanks cooled by river water or seawater / river water, but this results in poor cooling and corrosion. Summary of the Invention

[0032] The utility model is not limited to the following specific embodiments. All equivalent modifications based on the technical solution of this application fall within the scope of protection of the utility model. All components and devices in the utility model, unless otherwise specified, are all components and devices known in the prior art.

[0033] Example 1

[0034] This embodiment discloses an amphibious heat dissipation device for a transmission, comprising a first heat dissipation unit, the first heat dissipation unit comprising a fan heat dissipation mechanism 1, the fan heat dissipation mechanism 1 comprising a first radiator 1-1, and an oil cooler 2 externally connected to a transmission B. The coolant outlet of a first engine A1 is sequentially connected in series with the oil cooler 2 and the first radiator 1-1, and is cyclically connected to the coolant inlet of the first engine A1.

[0035] The first heat dissipation unit further includes a first air cooling assembly 3 in a loop connection with the first engine A1, a first fuel cooler 4, and a first water tank 7. The fan heat dissipation mechanism 1 further includes a second radiator 1-2. The outlet of the first water tank 7 is sequentially connected in series with the first air cooling assembly 3, the first fuel cooler 4, and the second radiator 1-2 and is loop-connected to the inlet of the first water tank 7.

[0036] Its function is as follows: when the amphibious power system is operating on land, the engine coolant in the first engine A1 flows from the first engine A1 into the oil cooler 2 connected to the transmission B to cool the transmission oil. The coolant then flows to the first radiator 1-1 for cooling before circulating back to the first engine A1 to further cool it, thus achieving a circulating cooling system. Simultaneously, the charge air in the first engine A1 is cooled by the first air-cooling assembly 3, which draws its cooling water from a separate cooling water source. During land operation, water is drawn from the first water tank 7, sequentially entering the first air-cooling assembly 3 and the first fuel cooler 4, then entering the second radiator 1-2 for cooling, and finally returning to the first water tank 7, completing the circulation. Throughout this process, both the coolant and the charge air in the first engine A1 are cooled. The coolant in the first engine A1 flows directly into the first radiator 1-1 for cooling, while the charge air is cooled by the coolant in the first water tank 7. The cooling water in the first water tank 7 then flows into the second radiator 1-2 for cooling. The overall structure is easy to implement, and can achieve simultaneous cooling of the coolant and the pressurized air of the first engine A1 to achieve a heat dissipation effect. At the same time, the transmission B and the fuel can also be cooled and dissipated, solving the heat dissipation problem of the amphibious power system.

[0037] The first engine A1 disclosed in this embodiment is a diesel engine model M16UI. The water tank interface of the first engine A1 is externally connected to a second water tank 8 to ensure the proper engine coolant level and to remove gas and bubbles from the engine coolant. Transmission B is preferably a hydraulic automatic transmission model F6A75. The fan cooling mechanism 1 is preferably an AKG AEL1+AEL3, comprising a first radiator 1-1 and a second radiator 1-2. The first radiator 1-1 is a high-temperature radiator with an optimal inlet temperature of 95°C before cooling and an optimal outlet temperature of 80°C after cooling. The second radiator 1-2 is a low-temperature radiator with an optimal inlet temperature of 55°C before cooling and an optimal outlet temperature of 40°C after cooling. The oil cooler 2 is preferably a hydraulic automatic transmission oil cooler model 81818810-1. The first water tank 7 is an expansion tank.

[0038] The first air-cooling assembly 3 disclosed in this embodiment includes a second air cooler 3-2 and a first air cooler 3-1 connected in series. The second air cooler 3-2 and the first air cooler 3-1 are each cyclically connected to the first engine A1. Both the second air cooler 3-2 and the first air cooler 3-1 are preferably AKG 48A2-205 air coolers.

[0039] Among them, a first water pump 7-1 is also provided at the outlet of the first water tank 7 to provide power for the circulation of the coolant in the first water tank 7.

[0040] Specifically, it also includes a second heat dissipation unit, which includes a first plate cooler 5 and a second plate cooler 6; the coolant outlet of the first engine A1 is connected in series with the second plate cooler 6 and is circulated to the coolant inlet of the first engine A1; the outlet of the first water tank 7 is connected in series with the first air cooling component 3, the first fuel cooler 4 and the first plate cooler 5 in sequence and is circulated to the inlet of the first water tank 7; a first three-way valve a is provided between the first engine A1, the oil cooler 2 and the second plate cooler 6, a second three-way valve b is provided between the first fuel cooler 4, the second radiator 1-2 and the first plate cooler 5, a third three-way valve c is provided between the first water tank 7, the second radiator 1-2 and the first plate cooler 5, and a fourth three-way valve d is provided between the first engine A1, the first radiator 1-1 and the second plate cooler 6;

[0041] Its function is as follows: When the amphibious power system is operating on water, the first three-way valve a, the second three-way valve b, and the fourth three-way valve d's outlet 0, as well as the third three-way valve c's inlet, are closed. The first and second plate coolers 5 and 6 begin operating, and the seawater / river water cools the coolant. The engine coolant in the first engine A1 flows from the first engine A1 to the first three-way valve a and out of port 1. It then flows to the second plate cooler 6, where it is cooled and then flows to port 1 of the fourth three-way valve d. Finally, it circulates back to the first engine A1. Engine A1 requires two streams of charge air to cool, entering the first air cooler 3-1 and second air cooler 3-2, respectively, before returning to engine A1. Similar to the requirements for land operation, a separate cooling water stream cools the charge air. When operating on water, water is drawn from the first water tank 7 and fed into the first water pump 7-1. The water then flows sequentially into the second air cooler 3-2, the first air cooler 3-1, and the first fuel cooler 4. The water then enters the second three-way valve b and exits through port 1 to the first plate cooler 5. Finally, it passes through port 1 and port 0 of the third three-way valve c, returning to the first water tank 7 to complete the cycle. When operating on water, both engine A1's coolant and the charge air are cooled. The first engine A1's coolant flows directly into the second plate cooler 6 for cooling, while the charge air is cooled by the coolant in the first water tank 7. The cooling water in the first water tank 7 then flows into the second plate cooler 6 for cooling.

[0042] The first plate cooler 5 is low temperature, with a coolant inlet temperature of ≤70°C, and the second plate cooler 6 is high temperature, with a coolant inlet temperature of ≤95°C.

[0043] Specifically, the seawater inlet of the first plate cooler 5 is further provided with a first seawater introduction unit 5-1, and the seawater outlet of the first plate cooler 5 is connected in series with the seawater inlet of the second plate cooler 6. That is, low-temperature seawater / river water is introduced into the first and second plate coolers 5, 6, through the first seawater introduction unit 5-1, cooling the coolant in the first and second plate coolers 5, 6 in turn.

[0044] The first seawater introduction unit 5-1 disclosed in this embodiment includes a jet pump 5-11, a switch 5-12, a filter 5-13 and an electric pump 5-14 connected in series in sequence; the jet pump 5-11 to the electric pump 5-14 suck up seawater / river water, and the seawater / river water is filtered through the filter 5-13 and then enters the first plate cooler 5 and the second plate cooler 6 in sequence.

[0045] At the same time, when the amphibious power system is working on water, it also includes a third heat dissipation unit connected to the second engine A2, the third heat dissipation unit includes a third plate cooler 12 and a fourth plate cooler 13, the coolant outlet of the second engine A2 is connected in series with the fourth plate cooler 13 and is cyclically connected to the coolant inlet of the second engine A2, and also includes a third water tank 11, a second air cooling component 9 and a second fuel cooler 10 that are cyclically connected in series with the third plate cooler 12 in sequence, and the second air cooling component 9 is cyclically connected to the second engine A2; the second air cooling component 9 includes a third air cooler 9-1 and a fourth air cooler 9-2 that are connected in series in sequence, and the third air cooler 9-1 and the fourth air cooler 9-2 are respectively cyclically connected to the first engine A1.

[0046] The cooling method of the second engine A2 by the third heat dissipation unit disclosed in this embodiment is exactly the same as the cooling method of the first engine A1 when the system is working on water, and will not be repeated here.

Therefore, two engines can be used for traveling on the water, and both engines can run at full power, so that the system can achieve a water speed of more than 80km / h, reaching the world's advanced level.
