Description of the invention: [Technical field to which the invention pertains] The present invention provides a type of fan, in particular, an isotropic feature in which a stator of a driving module is a three-dimensional wing, I, and _ deleting, coffee, and fine materials. A fan that combines a three-dimensional shape flux path. ° [Prior Art] According to 'in recent years, due to the continuous operation of the internal processor (cPU) of the computer, the generation of high power consumption and high freshness _, the trend ^ for the performance requirements of the thermal module More and more high. The conventional heat dissipation method is mainly for recording the upper part of the CPU, and the _MPU is transmitted to the fins. Then, the fan is introduced through the fan above the radiator to introduce the outside cold air, and the heat is dissipated by the forced convection airflow flowing through the surface of the fin, so the fan It plays a very important role in the cooling module of a personal computer. The conventional cooling fan is mainly _leaf, motor and fan Gu Cheng; in the sergeant, the motor is fixed on the fan seat and combined with the fan by the shaft core set in the bearing, and connected to the blade of the wind reduction, and then By energizing the coil of the traitor and inductive stimuli of the rotor, the stator system (four) is stacked and stacked, so that the motor can only be driven by a two-dimensional magnetic circuit; in addition to the magnetic leakage is quite heavy, Since the components of the motor must be installed in the middle of the fan, the motor structure is designed to turn off, so that the wind ride can only be made flat; and since the fan valley occupies a relatively large air outlet area, it is fixed at 200917010. In terms of the fan blowing the transmitted heat sink, the heat of the CPU is directly below the fan valley of the library. The square piece is exactly the most windy to cool the hottest spot on the film* Pure 4 is relatively well-known in the shape of the plane and the relatives of the wind: the blockage of the airflow of the core, so that it can not effectively cool the outside to the hottest _ in the center, resulting in loose _ performance is not good, : (4) called fan speed In order to increase the air volume and wind pressure may make The noise of the fan is increased by one right, so the heat pipe is added to the outside of the collar to enhance the heat dissipation performance, which will make the manufacturing cost worse. Except that the size of the wind is limited by the size of the riding stator, the magnetic pumping of the Shishi steel sheet will be suppressed. The content of si) decreases and the content of cut is 6 t % 6 · 5 wt %, the magnetic loss is the lowest; but the relative brittleness of the material is also increased 'very _; the cap is formed into a thin sheet, which is why the tradition The content of 11 content of Shixi Steel Sheet is mostly _ below 3 wt%; but it can be known from the material properties that the difference in magnetic loss is even 5 1 〇. Right can use a material with lower magnetic loss, which will effectively reduce the voltage and energy loss of the motor. In addition to the above-mentioned materials and the size of the fan hub, the current silicon steel motor fan also has many problems when assembled to the fan; for example, 200917010 to avoid the failure of the fan caused by the breakage of the enameled wire and to maintain The magnetic properties are coated with a layer of magnesium citrate (Mg S i 〇 4 ) on the surface of the silicon steel sheet, so there will be a thin layer of gap between the steel sheets, which can reduce the thirst flow loss but also cause The magnetic properties of the silicon steel sheet are severely attenuated; and the side of the Shixi steel sheet is made of ink, so there is no insulation. Therefore, the upper and lower sides of the stator of the heat-dissipating fan will use plastic gaskets to improve the insulation effect and help the niche. In addition to the large gaps in the winding of the copper wire, Ren also increases the length of the winding * increases the copper loss, these assembly will affect and limit the magnetic characteristics of the motor. For the motor itself, 'how to maintain the magnetic properties of the original magnetic material is important for the phase b& let the fan motor have stronger torque to drive the larger wind. 'The advantage of increasing the fan motor stator magnetic miscellaneous is that the motor can be made At the same working voltage, the greater the torque, from the resistance to the increase in the effect of 'reducing the riding of the stator's finger can reduce the length of the Ma Nuzi around the copper wire: thus greatly reducing the temperature caused by the "copper loss" In addition to the rising effect, it is possible to further reduce the wind and impurity area, and the heat dissipation efficiency of the entire heat dissipation module. "^ Generally, in the AC magnetic field, the induced magnetic flux density will vary with the magnetic field (8), and there will be a delay in the phase, and the loss of _ energy will generate heat, called magnetic loss _ loss (ir 〇 n ! 〇ss or 6 1 〇ss), the iron loss mainly includes magnetic hysteresis loss and eddy current loss, 200917010 where the amount of magnetic hysteresis loss is related to the hysteresis series (the area of β, as for the field changes around eddy and urVe) The resulting (four) born in the magnetic material 'is from the magnetic _ ^, the ratio of the thickness of the material of the vortex, is inversely proportional to the resistance of the magnetic material. t vortex damage will lead to a decrease in the material (4) In addition to the current method of using the paste, it is punched into a thinner thickness of 0.3mm. The eddy current loss of Shixigang is lower than the thickness of 〇5__Xishishan steel sheet _), increasing the grain boundary of the magnetic material. Resistance and lower magnetic loss _ Sex material is also a good way to do it. The magnet stator is usually made of magnetic powder material. The thickness of the motor stator that is formed by twisting, machining, or casting is much thicker than that of the stamping material. As mentioned above, due to the thirst and the thickness of the magnetic material. The square is proportional, so the motor stator made by the above method, if the stator shape is similar to the shape of the stator of the two-dimensional magnetic flux path generated by the conventional Shishi steel sheet, the motor performance will be lower than that of the conventional motor using the silicon steel sheet. As far as the concept of motor design is concerned, since the powder itself has an isotropic property, the motor stator can be designed in a red body to form a three-dimensional magnetic flux path, and the magnetic flux area is increased to greatly increase the torque. Therefore, the design and structure of the existing fan motor stator for heat dissipation are changed to use different magnetic materials to increase the magnetic characteristics of the motor and reduce the eddy current loss, so as to effectively utilize the design of the motor's three-shaped magnetic circuit to improve the performance and wind of the fan. The amount of 200917010 is the direction of the relevant manufacturers engaged in this industry.
