Description

Technical Field

[0001] This utility model relates to the field of transmission box technology, and in particular, to a high-efficiency heat dissipation transmission box. Background Technology

[0002] The transmission housing is a core structural component in mechanical transmission devices, used to support gears, shafts, bearings, and other transmission parts. Its main function is to fix the spatial positioning of the transmission system and transmit loads; typical equipment includes reducers and gearboxes. During operation, the internal temperature of the transmission housing rises due to the continuous operation of the internal transmission components. If this internal heat cannot be dissipated in time, it will accelerate component fatigue and reduce service life. Therefore, heat dissipation is necessary for transmission housings during use. Traditional heat dissipation methods generally fall into two categories: one is to create ventilation holes in the transmission housing and then use a cooling fan to expel heat through these holes; the other is to add fins to the outer wall of the transmission housing to increase the heat dissipation area and improve heat dissipation. Both of these methods are suitable for transmission housings with low heat generation. However, for transmission housings under high load conditions, the internal heat generation is enormous, and exhaust fans and added fins are insufficient to meet the demand for timely heat dissipation. Therefore, the inventors need to provide a transmission housing that can achieve efficient heat dissipation. Utility Model Content

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please see Figures 1-3 This utility model provides a high-efficiency heat dissipation transmission box, including a transmission box body 1, which is a hollow structure, and its interior is used to install components such as gears, bearings, and transmission shafts. The top of the transmission box body 1 has an exhaust port 11, and an exhaust fan 2 is installed on the exhaust port 11. A heat dissipation circulation pipe 3 is provided around the outside of the transmission box body 1. The heat dissipation circulation pipe 3 includes a fitting pipe 31 that is attached to the outer wall of the transmission box body 1 and a separation pipe 32 that is separated from the outer wall of the transmission box body 1. Cooling water circulates in the heat dissipation circulation pipe 3. A heat spreader plate 4 is provided on the transmission box body 1. The heat spreader plate 4 includes a bottom plate 41 and a side plate 42 that are connected to each other. The heat spreader plate 4 has a closed cavity, and a phase change working fluid is provided in the closed cavity. The bottom plate 41 is fixedly connected to the lower surface of the transmission box body 1. The side plate 42 is inclined and located close to the separation pipe 32. A heat dissipation fan 5 is installed on the side wall of the transmission box body 1. The air blown by the heat dissipation fan 5 passes through the separation pipe 32 and the side plate 42 in sequence. It should be noted that when the phase change working fluid is not heated and evaporated, the liquid phase change working fluid is only located within the bottom plate 41. The phase change working fluid can be alcohol.

[0021] This utility model's high-efficiency heat dissipation transmission housing, during operation, activates the exhaust fan 2, which discharges heat from the transmission housing body 1 to the outside of the transmission housing body 1 through the exhaust port 11. Simultaneously, cooling water flowing through the heat dissipation circulation pipe 3 carries away heat from the outer surface of the transmission housing body 1, further enhancing the heat dissipation effect. During operation, heat transferred from the transmission housing body 1 to its lower surface is transferred to the base plate 41. The phase-change liquid working fluid within the cavity of the base plate 41 absorbs heat in a low-vacuum environment and begins to evaporate, rapidly expanding and quickly filling the entire cavity with gaseous working fluid. At this time, the air blown out by the cooling fan 5 decreases in temperature after passing through the separation pipe 32. When passing through the side plate 42, the gaseous working fluid within the side plate 42 condenses upon cooling, releasing the heat accumulated during evaporation. The condensed liquid working fluid then flows back into the base plate 41 through internal capillaries, thus continuously and promptly dissipating heat.

[0022] In this embodiment, the heat dissipation circulation pipe 3 has a rectangular cross-section, the outer periphery of the transmission box body 1 is rectangular, and the bonding pipe 31 is formed by the three sides of the heat dissipation circulation pipe 3. The bonding pipe 31 is tightly bonded to the outer wall of the transmission box body 1, ensuring that the heat on the transmission box body 1 can be fully transferred to the heat dissipation circulation pipe 3. The separation pipe 32 is connected to the bonding pipe 31. There are multiple separation pipes 32, which are arranged in parallel. A ventilation slot 321 is formed between each pair of adjacent separation pipes 32. The heat dissipation fan 5 is located on the side of the separation pipe 32 away from the side plate 42. During operation, the air blown out by the heat dissipation fan 5 can pass through the ventilation slot 321 and the separation pipe 32, thereby reducing the temperature of the air. When the low-temperature airflow flows to the side plate 42, it can accelerate the condensation of the gaseous working fluid in the side plate 42 and accelerate the change of the phase change working fluid state in the heat exchange plate 4, thereby promoting heat dissipation.

[0023] The cooling fan 5 is fixedly installed on the side wall of the transmission box body 1. The air inlet of the cooling fan 5 is located at the bottom, and the air outlet of the cooling fan 5 is set directly opposite the separation pipe 32.

[0024] In this embodiment, the top portion of the side plate 42 is bent outward to form multiple fins 421. The fins 421 are perpendicular to the side plate 42, and an air duct 422 is formed between each pair of adjacent fins 421. During operation, the air blown out by the cooling fan 5 flows through the air duct 422 after passing through the separation pipe 32, thereby ensuring full contact between the airflow and the fins 421 and greatly improving the heat transfer efficiency.

[0025] In a preferred embodiment, the heat dissipation circulation pipe 3 is provided with an inlet 311 and an outlet 312, both of which are connected to the heat dissipation circulation pipe 3. The separator pipe 32 is positioned close to the inlet 311. In use, circulating cooling water enters the heat dissipation circulation pipe 3 through the inlet 311, preferentially passing through the separator pipe 32, which is closer to the inlet 311. At this point, the temperature of the cooling water entering the heat dissipation circulation pipe 3 is relatively low, ensuring that the cooling capacity on the separator pipe 32 is transferred to the side plate 42 under the action of the cooling fan 5, thereby ensuring the efficient operation of the heat spreader 4. Specifically, the inlet 311 and outlet 312 are respectively connected to the cooling water tank through pipes, and the cooling water circulates under the action of a water pump on the pipes.

[0026] The transmission housing body 1 includes a shell 12 with an opening at the lower end and a chassis 13 mounted on the bottom of the shell 12. A mounting groove 131 is formed on the lower surface of the chassis 13, and a base plate 41 is fitted into the mounting groove 131 to ensure that as much heat as possible from the transmission housing body 1 can be transferred to the base plate 41. In a preferred embodiment, the lower surface of the chassis 13 is coplanar with the lower surface of the base plate 41 to ensure consistency in the external structure and to prevent the base plate 41 from protruding from the lower surface of the chassis 13, thus avoiding interference with the installation operation of the transmission housing body 1. Furthermore, the base plate 41 and the chassis 13 are fixedly connected by welding to ensure the strength of the connection between them.

[0027] As a preferred embodiment, a wing plate 14 is fixedly connected to the outer wall of the transmission box body 1. The wing plate 14 increases the heat exchange area of ​​the transmission box body 1, which is beneficial for efficient heat dissipation.

[0028] In this embodiment, the air inlet of the exhaust fan 2 is located at the bottom, and the air outlet of the exhaust fan 2 is located at the top. When the exhaust fan 2 is started, the hot airflow inside the transmission box body 1 enters the exhaust fan 2 through the air inlet at the bottom, and then flows out to the outside of the transmission box body 1 through the air outlet at the top. According to the principle of hot airflow rising, the exhaust port 11 is located at the top of the transmission box body 1, which makes the exhaust direction of the exhaust fan 2 consistent with the airflow direction, which helps the heat to dissipate more quickly.

[0029] The high-efficiency heat dissipation transmission box of this utility model has a heat spreader plate 4 installed at the bottom of the transmission box body 1. The heat spreader plate 4 transfers heat through the phase change process of evaporation and condensation of the phase change working fluid, which can quickly conduct heat from the heat source to the cooling area. Compared with other heat dissipation methods, its thermal conductivity is outstanding. At the same time, the cooling fan 5 set on one side of the separation pipe 32 can apply the cooling energy of the cooling water flowing through the separation pipe 32 to the side plate 42 of the heat spreader plate 4, thereby accelerating the condensation of the phase change working fluid and further improving the heat dissipation efficiency.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
