Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for motor housings, and in particular to a motor housing with an auxiliary heat dissipation structure. Background Technology

[0002] The motor housing is the protective structure of the motor, mainly made of metal, to prevent external contaminants from entering and to ensure the safety of the internal components. Motors generate heat during operation; poor heat dissipation can lead to excessively high temperatures, affecting efficiency and lifespan. Therefore, auxiliary cooling mechanisms are needed to accelerate heat dissipation during operation, preventing overheating and ensuring stable motor operation.

[0003] Traditional motor housing heat dissipation auxiliary mechanisms are divided into air cooling, water cooling, and a combination of air and water cooling. Among them, water cooling is achieved by using a single spiral tube, that is, a spiral tube is set on the inner wall of the housing and coolant is introduced into the spiral tube. The coolant absorbs and carries away the heat, thereby completing the heat dissipation.

[0004] When a traditional motor casing uses a single spiral tube for water cooling, the coolant continuously absorbs heat as it flows from the inlet to the outlet due to the relatively long tube length, causing its temperature to gradually rise. This results in a significant decrease in the heat dissipation capacity of the coolant at the rear of the spiral tube, making it unable to effectively remove heat from the casing. Consequently, the temperature at the rear of the motor remains higher than at the front, creating localized hot spots. Utility Model Content

[0005] Therefore, it is necessary to provide a motor housing with an auxiliary heat dissipation structure to address the problem of uneven heat dissipation.

[0006] A motor housing with an auxiliary heat dissipation structure includes: a housing, wherein two support legs are mounted on the bottom end of the housing;

[0007] The heat dissipation mechanism includes multiple spiral tubes disposed on the inner wall of the housing. Each spiral tube is connected to an inlet pipe and an outlet pipe at both ends. The top ends of the multiple inlet pipes are connected to a central pipe. An adjustment component is disposed between the central pipe and the inlet pipes.

[0008] In one embodiment, multiple spiral tubes are evenly arranged on the inner wall of the shell and enclose the interior of the shell. Multiple liquid outlet tubes are interconnected. A one-way valve is provided inside each liquid outlet tube. Both the liquid inlet tube and the liquid outlet tube penetrate the shell.

[0009] In one embodiment, the regulating component includes a connecting pipe disposed between the central pipe and the inlet pipe, the central pipe and the inlet pipe being connected by the connecting pipe, and an regulating shell being disposed inside the connecting pipe.

[0010] In one embodiment, the surface of the regulating shell is provided with a plurality of water inlets near the bottom end, and the bottom end of the inner wall of the connecting pipe is provided with an annular groove that mates with the water inlets.

[0011] In one embodiment, two sliders are fixedly connected to the surface of the adjusting shell, the two sliders are arranged opposite to each other, and two grooves are correspondingly formed on the inner wall of the connecting tube. The adjusting shell is slidably connected to the connecting tube through the sliders cooperating with the grooves.

[0012] In one embodiment, a limiting rod is fixedly connected inside the groove, the limiting rod passes through the slider, and the slider is slidably connected to the surface of the limiting rod.

[0013] In one embodiment, a spring is fitted onto the surface of the limiting rod, with the top end of the spring fixedly connected to the slider and the bottom end fixedly connected to the bottom of the groove.

[0014] In one embodiment, a coolant distributor is mounted on the surface of the housing, and both the central pipe and the outlet pipe are connected to the interior of the coolant distributor.

[0015] Beneficial effects

[0016] 1. By uniformly arranging multiple spiral tubes inside the shell, heat is dissipated inside the shell. The length of a single spiral tube is reduced, thereby reducing the movement distance of the coolant in each spiral tube. This reduces the problem of reduced heat dissipation effect caused by the accumulation of a large amount of heat when the coolant moves in a single spiral tube. At the same time, multiple water inlet pipes are connected to the water collection pipe to ensure that water enters and exits in multiple spiral tubes at the same time, further improving the uniformity of heat dissipation inside the machine body.

[0017] 2. By installing an adjustment component between the water collection pipe and the water inlet pipe, coolant flows into several water inlet pipes simultaneously when the water pressure in the water collection pipe reaches a certain value. This ensures that the coolant flow rate is uniform across multiple water inlet pipes, avoiding uneven coolant flow distribution and further improving heat dissipation efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-5 This invention describes a motor housing with an auxiliary heat dissipation structure.

[0028] In one embodiment, a motor housing with an auxiliary heat dissipation structure includes: a housing 100, and two support legs 200 are mounted on the bottom end of the housing 100;

[0029] The heat dissipation mechanism 300 includes multiple spiral tubes 310 disposed on the inner wall of the housing 100. The two ends of the spiral tubes 310 are respectively connected to the liquid inlet pipe 320 and the liquid outlet pipe 330. The top ends of the multiple liquid inlet pipes 320 are connected to the central pipe 321. An adjustment component 350 is disposed between the central pipe 321 and the liquid inlet pipes 320.

[0030] In this device, a wind guide shroud is provided at one end of the housing 100, and a fan is provided between the wind guide shroud and the housing 100. The fan is connected to the motor rotor. When the motor starts, it will drive the fan blades to rotate synchronously, forming a directional airflow, thereby dissipating heat from the inside of the housing 100.

[0031] As shown in Figure 2 Figure 3 Figure 4 and Figure 5 As shown, multiple spiral tubes 310 are evenly arranged on the inner wall of the housing 100, enclosing the interior of the housing 100. Multiple outlet tubes 330 are interconnected, and a one-way valve is installed inside each outlet tube 330. Both the inlet tube 320 and the outlet tube 330 penetrate the housing 100. The regulating assembly 350 includes a connecting tube 351 disposed between the central tube 321 and the inlet tube 320. The central tube 321 and the inlet tube 320 are connected through the connecting tube 351, and an regulating shell 352 is disposed inside the connecting tube 351. Multiple water inlets 3521 are opened on the surface of the regulating shell 352 near the bottom end. An annular groove that mates with the water inlets 3521 is provided at the bottom end of the inner wall of the connecting tube 351. Two sliders 3522 are fixedly connected to the surface of the regulating shell 352. The two sliders 3522 are arranged opposite each other. Two corresponding sliding grooves are opened on the inner wall of the connecting tube 351. The regulating shell 352 is slidably connected to the connecting tube 351 through the sliders 3522 engaging with the sliding grooves. A limiting rod 3523 is fixedly connected inside the slide groove. The limiting rod 3523 passes through the slider 3522, and the slider 3522 is slidably connected to the surface of the limiting rod 3523. A spring 3524 is sleeved on the surface of the limiting rod 3523. The top end of the spring 3524 is fixedly connected to the slider 3522, and the bottom end is fixedly connected to the bottom of the slide groove.

[0032] In this embodiment, coolant continuously flows into the water collection pipe under the action of the coolant distributor 340. The coolant entering the water collection pipe enters the regulating shell 352. As the pressure in the water collection pipe gradually increases, the coolant pushes the regulating shell 352 away from the water collection pipe. At this time, the sliders 3522 at both ends of the regulating shell 352 slide in the groove of the connecting pipe 351 and compress the spring 3524 until the bottom end of the regulating shell 352 is flush with the bottom end of the connecting pipe 351. At this time, the water passage is completely in the annular groove, and the sliders 3522 move synchronously to the bottom end of the groove. The regulating shell 352 can no longer move, and the coolant continues to enter the connecting pipe 351. After passing through the connecting pipe 351, it is collected by a collection shell and then enters the water inlet pipe. The bottom surface of the regulating shell 352 and the connecting pipe 351... The inner walls are all made of rubber to improve the sealing between the regulating shell 352 and the connecting pipe 351. When the motor is first started, before the pressure in the water collection pipe reaches a certain value, the top of the regulating shell 352 is flush with the top of the connecting pipe 351 under the action of the spring 3524, while the water inlet 3521 at its bottom is blocked by the inner wall of the connecting pipe 351. At this time, the coolant cannot enter the connecting pipe 351 through the water inlet. The coolant fills the central pipe 321 and the cooling shell. The coolant flowing through the spiral pipe 310 will flow out from the corresponding outlet pipe. Each spiral pipe 310 is equipped with a branch pipe. The top of multiple branch pipes is connected to the main pipe. A one-way valve is set between each branch pipe and the main pipe so that the coolant can only flow from the branch pipe to the main pipe, so as to prevent the branch pipe at the front end from affecting the liquid flow of the branch pipe at the rear end.

[0033] It should be noted that the cooling mechanism of this device optimizes the traditional single spiral tube 310 into multiple spiral tubes 310. Although the number increases, the total length remains unchanged. Therefore, the spiral tubes 310 of this device will not affect the installation. At the same time, the heat dissipation mechanism 300 of this device is located on the inner wall and the outside of the housing 100, so it will not affect the installation of the motor components inside. In addition, this device only dissipates heat inside the motor and will not affect the normal operation of the motor.

[0034] like Figure 1 and Figure 2 As shown, a coolant distributor 340 is installed on the surface of the housing 100, and the central pipe 321 and the outlet pipe 330 are all connected to the interior of the coolant distributor 340.

[0035] In this embodiment, the coolant distributor 340 is a GTO52 type coolant distributor 340, which mainly consists of the following components:

[0036] The reservoir is used to store coolant.

[0037] Centrifugal pumps are used to power the flow of coolant;

[0038] Two connecting channels are connected to the water collection pipe and the water outlet pipe respectively, so that the coolant circulates within the housing 100;

[0039] The coolant distributor 340 is equipped with a radiator. The radiator has a dense array of microchannels inside. After absorbing heat, the coolant enters multiple microchannels to increase the contact area with the air. The air is guided to the surface of the radiator through natural convection, so that the coolant and the air can exchange heat and keep the coolant temperature lower than the temperature inside the housing 100.

[0040] Working principle: When the motor is started, the coolant distributor 340 starts simultaneously, allowing the coolant inside to flow into the central pipe 321. As the amount of coolant in the central pipe 321 increases, the pressure in the central pipe 321 gradually increases, and the coolant enters the regulating shell 352. As the pressure increases, the regulating shell 352 gradually slides towards the bottom of the connecting pipe 351. When the pressure in the central pipe 321 increases to a certain value, the bottom of the regulating shell 352 will be flush with the bottom of the connecting pipe 351. At this time, the water inlet 3521 of the regulating shell 352 connects with the annular slot at the bottom of the connecting pipe 351. The coolant will enter the inlet pipe 320 through the annular slot, and then flow into the spiral pipe 310 through the inlet pipe 320. By reducing heat transfer, the coolant absorbs the heat inside the housing 100, and then flows out through the outlet pipe 330 and into the coolant distributor 340, completing the circulation and thus continuously dissipating heat from the inside of the housing 100.

[0041] It should be noted that the coolant distributor 340, spring 3524, housing 100, support leg 200 and spiral tube 310 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the coolant distributor 340 can be powered by an internal power supply. The specific power supply method can be selected according to the situation, which will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
