[0024] The following will describe in detail the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and interpreting the present disclosure, and are not used to limit the present disclosure.

[0025] In the present disclosure, unless otherwise stated, the orientation terms such as "top" and "bottom" generally refer to the top and bottom of the corresponding components in the gravity direction in the use state, and "inside" and "outside" refer to the inside and outside relative to the contour of the component or structure itself. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0026] As Figure 1 shown, the present disclosure provides a heat dissipation device, including: a circulating oil circuit 4 for connecting with the gearbox 1 to pump out and return the gear oil in the gearbox 1; a water cooling component 3 and an air cooling component 2, both arranged on the circulating oil circuit 4 to cool the gear oil pumped out of the gearbox 1.

[0027] Through the above technical solution, in the heat dissipation device provided by the present disclosure, the gear oil in the gearbox 1 is pumped out through the circulating oil circuit 4, cooled by the water cooling component 3 and the air cooling component 2, and then transported back into the gearbox 1 to cool the gear oil, thereby cooling and lowering the temperature of the gearbox 1. The present disclosure simultaneously sets the water cooling component 3 and the air cooling component 2, which can improve the heat dissipation efficiency of the gear oil.

[0028] As an optional implementation manner, as Figures 1-3 shown, the water cooling component 3 includes a liquid-liquid heat exchanger 31, a cooling water pipe 33 and a water supply device 32. The liquid-liquid heat exchanger 31 is arranged on the circulating oil circuit 4. The liquid-liquid heat exchanger 31 is provided with a water inlet 311 and a water outlet 312. One end of the cooling water pipe 33 is connected to the water inlet 311, and the other end is connected to the water outlet 312 through the water supply device 32. The liquid-liquid heat exchanger 31 is used for heat exchange between liquids, and dissipates heat from the gear oil with cooling water. The water supply device 32 provides cooling water and the power required for the cooling water circulation for the liquid-liquid heat exchanger 31. For example, the water supply device 32 includes a water tank and a water pump, and is connected to the water inlet 311 and the water outlet 312 of the liquid-liquid heat exchanger 31 through the cooling water pipe 33 to form a cooling water circuit. Of course, the water cooling component 3 may also include a radiator arranged on the cooling water pipe 33 to dissipate heat from the cooled cooling water pipe 33.

[0029] Among them, as Figure 3 shown, the circulating oil circuit 4 includes an oil supply device 41, an oil suction pipe 42, and an oil return pipe 43. An oil inlet 313 and an oil outlet 314 are provided on the liquid-liquid heat exchanger 31. One end of the oil suction pipe 42 is used to connect to the oil drain port 11 on the gearbox 1, and the other end is connected to the oil inlet 313 through the oil supply device 41. One end of the oil return pipe 43 is connected to the oil outlet 314, and the other end is used to connect to the oil filling port 12 on the gearbox 1. For example, the oil drain port 11 can be arranged at the bottom of the gearbox 1 to facilitate the outflow of the gear oil. The oil supply device 41 provides the power required for the circulation of the gear oil and replenishes the gear oil when it is lacking. For example, the oil supply device 41 includes an oil pump and an oil tank. The gear oil is pumped out through the oil suction pipe 42, cooled by the liquid-liquid heat exchanger 31, and then flows back into the gearbox 1 through the oil return pipe 43 to complete the cooling and temperature reduction of the gear oil.

[0030] In addition, as Figure 3 shown, the heat dissipation device further includes a temperature measuring member 5. The temperature measuring member 5 is arranged on the oil suction pipe 42 and is used to detect the temperature of the gear oil pumped out from the gearbox 1. For example, the temperature measuring member 5 is a temperature sensor.

[0031] Optionally, as Figure 1 shown, the liquid-liquid heat exchanger 31 is used to be arranged on the gearbox 1. For example, it is arranged on the top of the gearbox 1. The liquid-liquid heat exchanger 31 is integrally installed with the gearbox 1, which can save space, eliminates the need to separately set an installation position for the liquid-liquid heat exchanger 31, and is convenient for installation and transportation at the same time.

[0032] As an optional implementation manner, as Figure 1 shown, the air-cooling assembly 2 is arranged on the water-cooling assembly 3. The air-cooling assembly 2 and the water-cooling assembly 3 are integrally arranged, eliminating the need to separately set an installation position for the air-cooling assembly 2. At the same time, multiple components are assembled together, which is convenient for transportation and installation.

[0033] Optionally, as Figures 1-2As shown, the liquid-liquid heat exchanger 31 is configured as a plate heat exchanger, and the air-cooling assembly 2 is configured as a fan. The fan is arranged on the plate heat exchanger, and the windward side or the leeward side of the fan faces the exposed part of the heat exchange plates of the plate heat exchanger. The plate heat exchanger is formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, convenient installation and cleaning, wide application, long service life, etc. Under the same pressure loss condition, its heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, and the floor area is one-third of that of the tubular heat exchanger. The fan cools the gear oil passing through the plate heat exchanger, and at the same time can also cool the cooling water. The fan can blow air towards the plate heat exchanger to cool the gear oil, or can blow air in the direction away from the plate heat exchanger to take away the heat.

[0034] As Figure 4 shown, the second object of the present disclosure is to provide a control system, including: the above-mentioned heat dissipation device; a temperature measuring member 5 for detecting the temperature of the gear oil; and a control member 6 for receiving the temperature signal of the temperature measuring member 5 and controlling the water-cooling assembly 3 and the air-cooling assembly 2 to work. For example, the control member 6 can be a single-chip microcomputer. The temperature measuring member 5 sends the temperature signal to the control member 6, and the control member 6 controls the water-cooling assembly 3 and the air-cooling assembly 2 to work through the temperature signal measured by the temperature measuring member 5.

[0035] Optionally, the control member 6 selectively controls the water-cooling assembly 3, and / or, the air-cooling assembly 2 to work. According to different temperatures, a suitable cooling method can be selected. The water-cooling assembly 3 can be used alone for cooling, or the air-cooling assembly 2 can be used alone for cooling, or the water-cooling assembly 3 and the air-cooling assembly 2 can be used simultaneously to cool the gear oil. Not only is the heat dissipation efficiency relatively high, but also the self-power consumption can be reduced.

[0036] As Figure 1 shown, the third object of the present disclosure is to provide a gearbox 1 assembly, including: a gearbox 1; and the above-mentioned control system. The control system is connected to the gearbox 1. The present disclosure simultaneously sets a water-cooling assembly 3 and an air-cooling assembly 2, and a suitable cooling method can be selected according to different temperatures, which can improve the heat dissipation efficiency of the gear oil and reduce the self-power consumption.
