It can change the torque, speed and direction of movement transmitted from the driving shaft to the driven shaft according to different working conditions. A gearbox is generally composed of a housing and several gear pairs.

[0003] The gearbox generates a lot of heat when it is running. At present, water cooling is often used to dissipate heat for the gearbox. The heat dissipation method is relatively simple, so the heat dissipation effect is average. For example, Chinese patent publication number CN208595224U discloses a gearbox with a heat dissipation device. By arranging a heat absorption pipe on the lower side of the gearbox body, the heat of the gearbox body can be transferred to the cooling water inside the heat absorption pipe. Its heat dissipation method is water cooling.

[0004] In addition, the temperature of the water in the cooling water tank will gradually increase after a period of use, resulting in a worse heat dissipation effect. In view of the above problems, it is urgent to develop a heat dissipation device for a gearbox that can maintain a low temperature state of the water flow and has a better heat dissipation effect.

DETAILED DESCRIPTION

[0035] In order to make the purpose, advantages and features of the present invention more clear, a heat dissipation device for a gearbox proposed by the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] A heat dissipation device for a gearbox, such as Figure 1As shown, it includes a gearbox body 1, a water storage tank 2, a circulating cooling mechanism 3, a blower mechanism 4 and a semiconductor cooling sheet 5. Figure 2 , Figure 3 As shown, the water storage tank 2 is arranged on one side of the gearbox body 1, and a plurality of semiconductor cooling sheets 5 are installed on a side wall of the water storage tank 2 away from the gearbox body 1 and are evenly arranged in an array, which is used to cool the water flow in the water storage tank 2, and the semiconductor cooling sheets 5 are connected to an external power supply. The top of the water storage tank 2 is detachably installed with an end cover 201, and water flow can be added to the water storage tank 2 by removing the end cover 201. The circulating cooling mechanism 3 is arranged on the side wall adjacent to the gearbox body 1 and the water storage tank 2, and its water inlet end and water outlet end are respectively connected to the water storage tank 2, which is used to dissipate heat from the gearbox body 1 through water cooling. The air blowing mechanism 4 is used to dissipate heat from the gearbox body 1 through air cooling, and the air blowing mechanism 4 is rotatably installed on the side wall adjacent to the water storage tank 2 and the gearbox body 1, and is located below the water outlet end of the circulating cooling mechanism 3. The air blowing end of the air blowing mechanism 4 is located outside the water storage tank 2, and the power end is located inside the water storage tank 2 and is arranged above the water surface.

[0037] When in use, the water flow in the water tank 2 is transported to the gearbox body 1 through the circulating cooling mechanism 3 to absorb heat, and then the circulating cooling mechanism 3 returns the water flow to the water tank 2. The reflux water sprayed by the circulating cooling mechanism 3 impacts the hair dryer mechanism 4, causing the hair dryer mechanism 4 to rotate. The rotation of the hair dryer mechanism 4 accelerates the circulation of air flow, thereby improving the heat dissipation effect. At the same time, the water flow in the water tank 2 is cooled by the semiconductor refrigeration sheet 5, and the water flow in the water tank 2 is kept at a lower temperature, thereby maintaining the heat dissipation effect.

[0038] like Figure 4 , Figure 5 As shown, the circulating cooling mechanism 3 includes a circulating water pump 301, an output pipe 302, a heat exchange pipe 303, a return pipe 304 and an impact nozzle 305. The circulating water pump 301 is installed at the bottom of the water storage tank 2 and is connected to one end of the heat exchange pipe 303 through the output pipe 302. The heat exchange pipe 303 is attached to the side wall adjacent to the gearbox body 1 and the water storage tank 2, and the other end is connected to the water storage tank 2 through the return pipe 304. The heat exchange pipe 303 is arranged in a bent and rotating form and is made of copper, so that it has good thermal conductivity. The impact nozzle 305 is installed at the end of the return pipe 304 and is located at the top of the water storage tank 2. The impact nozzle 305 is conical, and the large end is installed at the end of the return pipe 304, so that the water outlet at the bottom of the impact nozzle 305 becomes smaller, thereby accelerating the flow rate of the water flow and increasing the impact force on the blower mechanism 4. When in use, the water flow in the water storage tank 2 is transported to the heat exchange pipe 303 through the circulating water pump 301, and the heat on the gearbox body 1 is taken away by cold water. The water flow after absorbing heat flows back to the water storage tank 2 through the return pipe 304 and the impact nozzle 305.

[0039] The blower mechanism 4 includes a rotating shaft 401, a plurality of blades 402 and a plurality of fan blades 403. The rotating shaft 401 is rotatably connected to the side wall of the water storage tank 2 and is located above the water surface and below the impact nozzle 305. The plurality of blades 402 are mounted on one end of the rotating shaft 401 along the circumferential direction and are located inside the water storage tank 2 and above the water surface, and the blades 402 are located below the impact nozzle 305. The plurality of fan blades 403 are mounted on the other end of the rotating shaft 401 along the circumferential direction and are located outside the water storage tank 2 on one side close to the gearbox body 1. When in use, the water flow sprayed from the impact nozzle 305 impacts the blades 402, and the rotating shaft 401 is driven to rotate through the blades 402, and the fan blades 403 are driven to rotate through the rotation of the rotating shaft 401, and wind is generated through the rotation of the fan blades 403, thereby accelerating the flow of airflow.

[0040] The working principle of the heat dissipation device for the gearbox provided by the utility model is:

[0041] The water flow in the water storage tank 2 is transported to the heat exchange pipe 303 through the circulating water pump 301, and the heat on the gearbox body 1 is taken away by cold water, thereby dissipating the heat of the gearbox body 1. The water flow after absorbing heat flows back to the water storage tank 2 from the return pipe 304 and the impact nozzle 305, and the water flow sprayed from the impact nozzle 305 impacts the blade 402, and the rotating shaft 401 is driven to rotate by the blade 402, and the fan blade 403 is driven to rotate by the rotation of the rotating shaft 401, and the rotation of the fan blade 403 generates wind, thereby accelerating the flow of airflow and improving the heat dissipation effect of the gearbox body 1. At the same time, the water flow in the water storage tank 2 is cooled by the semiconductor refrigeration sheet 5, and the water flow in the water storage tank 2 is kept at a lower temperature, thereby maintaining a good heat dissipation effect.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solution of the utility model.
