Description

Technical Field

[0001] The utility model relates to the technical field of disc motors, in particular to a disc motor cooling structure. Background Art

[0002] The disc motor, also known as the disk motor, has the characteristics of small size, light weight and high efficiency. The rotor and stator of a general motor are installed inside and outside. In order to be thin, the disc motor has a stator on a flat substrate and a rotor covered on the stator. Generally, the stator is a coil and the rotor is a permanent magnet or a disc with a permanent magnet attached.

[0003] Most disc motors use forced air cooling and natural air cooling to dissipate heat during operation. However, the heat dissipation effect of natural air cooling is poor, especially when the motor works for a long time, the heat generated is high, and pure natural air cooling has the problem of insufficient heat dissipation, which affects the life and efficiency of the motor. Therefore, a disc motor cooling structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0007] Preferably, the inner side of the cold and heat exchange tube is connected and penetrated with the inner ring tube through a connecting tube, and the inner ring tube and the cold and heat exchange tube are placed and installed on the inner and outer sides of the stator core. The cold and heat exchange tube and the inner ring tube are connected and penetrated through the connecting tube, so that the coolant can flow between the cold and heat exchange tube and the inner ring tube.

[0008] Preferably, the buckle assembly includes a hook ring, which is buckled on the outside of the heat exchange tube. The center position of the outside of the hook ring is connected to a movable block, and the movable block is inserted into the inside of the frame through a through slot. The hook ring is buckled on the heat exchange tube to facilitate fine-tuning of the position of the heat exchange tube.

[0009] Preferably, a threaded shaft is inserted through a through hole on the outside of the frame, and the shaft end of the threaded shaft is inserted into the movable block through a threaded hole. The movable block is displaced on the surface of the threaded shaft by rotating the threaded shaft to ensure the convenience of hook and ring adjustment.

[0010] Preferably, the cover assembly comprises a cover plate, two plug-in plates are symmetrically connected to both sides of the cover plate, and the plug-in plates are inserted into the plate sleeve through slots. The plate sleeve can guide the plug-in plates so that the plug-in plates can be inserted into the plate sleeve.

[0011] Preferably, a locking bolt is inserted through a through hole on the outside of the plate sleeve, and the axial end of the locking bolt is inserted into the threaded hole of the plug plate.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting up a cooling component, rapid heat dissipation of the stator core is achieved. Compared with the traditional structure, the device places the inner ring tube and the heat exchange tube on the inner and outer sides of the stator core, so that the inner ring tube and the heat exchange tube are connected through the connecting tube. The coolant enters from the liquid inlet pipe, and the coolant passes through the liquid tank and is dispersed to the heat exchange tube and the inner ring tube to flow inside. The coolant in the heat exchange tube and the inner ring tube exchanges heat with the surface of the stator core. The heat generated by the stator core can be quickly taken away during the flow of the coolant, thereby improving the cooling effect of the disc motor unit and ensuring the life and efficiency of the disc motor unit.

[0015] 2. By setting up a cover group, dust can be intercepted during natural air cooling. The device fits the inner side of the arc plate through the inner buckle of the filter mesh plate, so that the arc plate is constrained after passing through the filter mesh plate. The filter mesh plate can intercept the adsorbed dust during air cooling to prevent dust from adsorbing and sticking to the surface of the stator core and affecting the heat dissipation effect. At the same time, the cover plate is buckled on the outside of the frame, so that the plug-in plate is inserted into the plate sleeve and locked by twisting the locking bolt, which is convenient for the staff to remove the cover plate and replace and clean the filter mesh plate.
