Description

Technical Field

[0001] This invention belongs to the field of motor housing technology, and specifically relates to a motor housing that facilitates heat dissipation. Background Technology

[0002] The motor housing serves as an external barrier for the motor, preventing dust, moisture, corrosive gases, metal shavings, and other contaminants from entering the motor and avoiding damage such as corrosion, wear, or short circuits to internal components. It also bears the weight of the internal parts and the inertial forces during operation, ensuring the relative stability of the various components inside the motor and guaranteeing normal operation. In addition, it also functions as electromagnetic shielding, heat dissipation, and insulation.

[0003] Motors generate a lot of heat when they are running. The motor housing can conduct internal heat to the external environment, which can play a role in heat dissipation, prevent the motor from overheating, maintain the motor within the normal operating temperature range, and extend the service life of the motor.

[0004] Currently, motors require heat dissipation, especially high-power motors that run for extended periods. While there are various heat dissipation methods available, such as liquid cooling, heat pipe cooling, and phase change materials, the high operating costs and the need for additional water pumps, heat pipes, or phase change materials mean that most motors still rely on natural cooling. However, natural cooling is too inefficient to be widely used in large and high-power motors.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a motor housing that facilitates heat dissipation.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0033] like Figures 1 to 9As shown, a heat-dissipating motor housing according to one embodiment of the present invention includes: a motor housing body 1, an air-collecting heat dissipation mechanism 2, and a pressure-type flow-blocking mechanism 3. The air-collecting heat dissipation mechanism 2 is installed on one side of the motor housing body 1. The air-collecting heat dissipation mechanism 2 includes an air-collecting component 21, a pair of cooling components 22, and a return flow component 23. The air-collecting component 21 is fixedly installed on one side of the motor housing body 1, the cooling components 22 are slidably installed inside the motor housing body 1, and the return flow component 23 is fixedly installed on the pair of cooling components 22. The pressure-type flow-blocking mechanism 3 is slidably installed inside the motor housing body 1. The pressure-type flow-blocking mechanism 3 includes a cleaning component 31 and a pair of flow-blocking components 32.

[0034] The method of using the heat-dissipating motor housing is as follows: After the motor housing body 1 is installed, when the motor is running, its rotating shaft will drive the air collection component 21, causing the air collection component 21 to continuously draw in outside air and inject the air into the cleaning component 31. The air can be continuously injected into the cooling component 22 through the flow-blocking component 32. At this time, the coolant in the cooling component 22 needs to be cooled after absorbing heat in order to improve the heat absorption efficiency of the coolant. After the air enters the cooling component 22, it will accelerate the cooling of the coolant. Through convection, the heat in the coolant can be exchanged. After the air enters the coolant, it can not only directly exchange heat, but also absorb the heat of the coolant. It can also enhance the convection, accelerate the heat diffusion inside the coolant, and promote evaporation, accelerating the heat loss in the coolant. The evaporated coolant will enter the return component 23 along with the airflow. After dehumidification and condensation by the return component 23, it will flow back into the cooling component 22.

[0035] like Figures 1 to 7 As shown, the air collection assembly 21 includes: an air collection pipe 211, an air collection filter 212, and an air collection fan 213. The air collection pipe 211 is fixedly installed on one side of the motor housing body 1. The air collection pipe 211 facilitates the installation of the air collection filter 212 and can also accommodate the air collection fan 213, guiding the airflow agitated by the air collection fan 213. The air collection filter 212 is fixedly installed inside the air collection pipe 211. Before air enters the air collection pipe 211, the air collection filter 212 can filter the air, reducing the probability of dust entering the air collection pipe 211, improving the cleanliness of the air collection pipe 211, making the operation of the air collection fan 213 more stable, and reducing the probability of dust entering the coolant. The air collecting fan 213 is rotatably installed inside the air collecting pipe 211 and can be driven to rotate by the rotating shaft of the motor. The rotation of the air collecting fan 213 can agitate the air inside the air collecting pipe 211, so that outside air can be continuously injected into the air collecting pipe 211 to replenish the air for the cooling component 22 at any time.

[0036] like Figures 1 to 5As shown, a first air-collecting bearing 214 is rotatably installed inside the air-collecting filter 212. The first air-collecting bearing 214 is in direct contact with the rotating shaft of the motor, which can reduce the friction between the air-collecting filter 212 and the rotating shaft, reduce the probability of the air-collecting filter 212 being driven by the rotating shaft, improve the stability of the air-collecting filter 212, and extend the service life of the air-collecting filter 212 and the rotating shaft of the motor. A second air-collecting bearing 215 is installed between the air-collecting fan 213 and the air-collecting pipe 211. The air-collecting fan 213 is in direct contact with the rotating shaft of the motor and can be driven by the rotating shaft to rotate. The setting of the second air-collecting bearing 215 can effectively reduce the friction between the air-collecting pipe 211 and the air-collecting fan 213, reduce the damage caused by friction, and extend the service life of the air-collecting pipe 211 and the air-collecting fan 213.

[0037] like Figures 1 to 3 As shown, the cooling assembly 22 includes: a cooling containment chamber 221, a cooling barrier mesh 222, a cooling vacuum chamber 223, and a cooling filament layer 224. The cooling containment chamber 221 is slidably installed within the motor housing body 1. The cooling containment chamber 221 can contain coolant, which can absorb heat from the motor, reducing the likelihood of overheating and extending the motor's lifespan. Simultaneously, the cooling containment chamber 221 can be removed for easy replenishment of coolant. The cooling barrier mesh 222 is fixedly installed within the cooling containment chamber 221, filtering out fine dust particles. This reduces the amount of dust entering the coolant, minimizing its impact on convection and improving the coolant's heat dissipation efficiency, while also reducing the impact of dust on the coolant's thermal conductivity. The cooling vacuum chamber 223 is fixedly installed within the cooling containment chamber 221 and extends through it. The cooling vacuum chamber 223 can also contain coolant with higher thermal conductivity and greater volatility, which can rapidly absorb heat from the motor through vaporization. The cooling filament layer 224 is fixedly installed inside the cooling vacuum chamber 223. The cooling filament layer 224 can significantly increase the thermal conductivity of the coolant inside the cooling vacuum chamber 223, significantly increase the contact area between the coolant and heat inside the cooling vacuum chamber 223, and make it easier for the coolant inside the cooling vacuum chamber 223 to vaporize, thereby improving heat dissipation efficiency.

[0038] like Figures 1 to 6 As shown, multiple uniformly distributed cooling fins 225 are fixedly installed inside the motor housing body 1. The cooling fins 225 can dissipate heat inside the motor and can be cooled by air circulation, providing auxiliary heat dissipation for the motor. The cooling fins 225 are set through the motor housing body 1. Multiple cooling vacuum chambers 223 are provided and are uniformly distributed.

[0039] like Figures 1 to 8As shown, the reflux assembly 23 includes: a reflux mounting chamber 231, a reflux liquefaction plate 232, multiple pairs of reflux fins 233, reflux absorbent cotton 234, and a reflux channel 235. The reflux mounting chamber 231 is fixedly installed above a pair of cooling containment chambers 221, collecting evaporated coolant and reducing the likelihood of direct discharge, thus minimizing coolant waste and extending coolant lifespan. The reflux liquefaction plate 232 is fixedly installed inside the reflux mounting chamber 231, condensing the evaporated coolant and allowing it to reflux, reducing coolant discharge. Multiple pairs of reflux fins 233 are fixedly installed on the reflux liquefaction plate 232, extending through the reflux mounting chamber 231 and evenly distributed. The reflux fins 233 directly cool the reflux liquefaction plate 232, improving its liquefaction efficiency. The reflux absorbent cotton 234 is fixedly installed inside the reflux liquefaction plate 232. It can absorb moisture in the air and absorb evaporated coolant. In conjunction with the reflux liquefaction plate 232, it further reduces the chance of coolant leakage. The reflux channel 235 is fixedly installed on the reflux installation chamber 231 and runs through the reflux installation chamber 231 and the reflux liquefaction plate 232. The reflux channel 235 provides a corresponding channel for air to be discharged.

[0040] like Figures 1 to 7 As shown, the cleaning assembly 31 includes: a cleaning sliding chamber 311, a pair of cleaning filters 312, and a cleaning air inlet pipe 313. The cleaning sliding chamber 311 is slidably installed inside the motor housing body 1 and extends through it. The cleaning sliding chamber 311 collects the dust filtered by the cleaning filters 312, preventing dust from re-entering the motor housing body 1 and allowing for cleaning during subsequent maintenance. The sliding nature of the cleaning chamber 311 facilitates cleaning by the user. A pair of cleaning filters 312 are fixedly installed on both sides of the cleaning sliding chamber 311. The cleaning filters 312 filter dust from the air, reducing the likelihood of dust entering the cooling reservoir 221 and improving the cleanliness of the coolant within the cooling reservoir 221. The cleaning air inlet pipe 313 is fixedly installed inside the motor housing body 1 and passes through the air collection pipe 211, the motor housing body 1 and the cleaning sliding chamber 311. The cleaning air inlet pipe 313 can connect the air collection pipe 211 and the cleaning sliding chamber 311.

[0041] like Figures 1 to 5 As shown, the air collection pipe 211 and the cleaning sliding chamber 311 are connected by the cleaning air inlet pipe 313. The air in the air collection pipe 211 can be continuously injected into the cleaning sliding chamber 311. After being filtered by the cleaning filter screen 312, it enters the motor housing body 1 and then enters the air collection pipe 211. The cleaning sliding chamber 311 has a fixing groove that matches the cleaning filter screen 312.

[0042] like Figures 1 to 7 As shown, the flow-blocking assembly 32 includes: a flow-blocking pipe 321, a flow-blocking pressure plate 322, a pair of flow-blocking balance bars 323, and a flow-blocking spring 324. The flow-blocking pipe 321 is fixedly installed inside the motor housing body 1 and extends through the cooling chamber 221. The flow-blocking pipe 321 connects the motor housing body 1 and the air collecting pipe 211, allowing air from inside the motor housing body 1 to enter the air collecting pipe 211, providing a continuous supply of air to the air collecting pipe 211. The flow-blocking pressure plate 322 is slidably installed inside the cooling chamber 221, which can seal the flow-blocking pipe 321, reducing the probability of coolant entering the flow-blocking pipe 321 from the air collecting pipe 211 and extending the coolant's service life. A pair of flow-blocking balance bars 323 are fixedly installed inside the cooling chamber 221. The flow-blocking pressure plate 322 can slide through the flow-blocking balance bars 323. The flow-blocking balance bars 323 provide corresponding balance for the sliding of the flow-blocking pressure plate 322, reducing the probability of the flow-blocking pressure plate 322 tilting and thus improving the stability of the flow-blocking pressure plate 322. The flow-blocking spring 324 is sleeved on the flow-blocking balance bars 323 and can compress the flow-blocking pressure plate 322, causing the flow-blocking pressure plate 322 to seal the flow-blocking pipe 321. When the air pressure inside the motor housing 1 can push open the flow-blocking pressure plate 322, air can enter the air collection pipe 211.

[0043] like Figures 1 to 8 As shown, the flow-blocking plate 322 is matched with the flow-blocking pipe 321, which reduces the probability of coolant leakage. The flow-blocking balance bar 323 is installed through the flow-blocking plate 322, and the flow-blocking spring 324 is installed between the flow-blocking balance bar 323 and the flow-blocking plate 322.
