Description

Technical Field

[0001] The present invention relates to the technical field of generators, and particularly to a cooling motor and a temperature regulation method thereof. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators have a wide range of applications in industrial and agricultural production, national defense, science and technology, and daily life.

[0003] The cooling of existing generators mainly adopts the method of forced cooling by fan blades. The fan blades rotate to generate an air flow to dissipate heat inside the generator, and the fan blades are usually installed on the rotor and rotate together with the rotor. There are mechanical losses during the operation of the generator. The mechanical losses mainly include ventilation losses and bearing losses. The change in bearing losses is relatively small, while the ventilation losses are generated due to the friction resistance between the rotating fan blades and the air, and are greatly related to the fan speed and air volume. The proportion of mechanical losses in the generator losses under the rated working conditions of the generator is relatively small, about 25% or so. However, when the generator operates under low load conditions, the proportion of mechanical losses in the generator losses will rise to about 50%, and the energy loss of the generator is relatively large.

The control component 40 is electrically connected to the wind driving component 30; the control component 40 includes a central control component (not shown in the figure) and a temperature measuring component 41 connected to the central control component; the central control component is used to control the rotation speed of the speed-regulating fan 35; the temperature measuring component 41 is used to detect the temperature of the power generation component 20 and the internal environment of the housing 10, and then transmit the temperature electrical signal to the central control component, and the central control component adjusts and controls the rotation speed of the speed-regulating fan 35 according to the temperature signal. The cooling component 50 is arranged in the cooling chamber 16, and the cooling component 50 is arranged between the air inlet 12 and the air outlet 13. The cooling component 50 is used to cool the air flow entering the cooling chamber 16 from the air outlet 13, thereby reducing the working environment temperature of the power generation component 20, achieving a better heat dissipation effect with a smaller air flow velocity, and further improving the operating efficiency of the engine.

[0047] For the above cooling motor 100, by setting an independent speed-regulating fan 35 to control the air flow, the adjustable change of the air flow velocity is ensured. When operating at low load, the rotation speed of the speed-regulating fan 35 can be reduced to lower the air flow velocity, thereby reducing the frictional loss between the air flow and the internal components, reducing the energy loss of the generator, and improving the operating efficiency; and by arranging a cooling component 50 in the housing 10 to cool the air flow, the heat dissipation efficiency is improved, a better heat dissipation effect can be achieved without a large air flow, the energy loss is reduced, and the operating efficiency of the generator is further improved.

[0048] Furthermore, the casing 10 is a hollow seal to cooperate with a cooling member 50 disposed inside the casing 10 to reduce the ambient temperature inside the casing 10; the partition 11 is arranged in a straight plate structure, and the edge of the partition 11 is fixedly connected to the inner side wall of the casing 10.

The air inlets 12 on both sides are correspondingly arranged at both ends of the power generation assembly 20, so that the circulating air flow flows from both ends to the middle position direction in the power generation chamber 15.

The two air outlets 13 are arranged side by side at the middle position of the partition 11. By arranging two air outlets 13 and respectively arranging them corresponding to the two air inlets 12, the formation of two independent circulating air flows is ensured. Compared with one circulating air flow, the heat dissipation area and heat dissipation effect are improved.

[0053] Further, a junction box 46 is provided on the outer side of the machine shell 10, and the junction box 46 is correspondingly electrically connected to the central control component. It can be understood that the central control component can control the speed of the speed control fan 35 by controlling the voltage applied to the speed control fan 35; it can also connect the speed control fan 35 to a PWM (Pulse Width Modulation, pulse width modulation is an analog control method that modulates the bias of the transistor base or MOS transistor gate according to the change of the corresponding load to change the conduction time of the transistor or MOS transistor, thereby realizing the change of the output of the switching regulated power supply) circuit, and control the speed of the speed control fan 35 through the central control component controlling the pulse signal of the PWM.

[0058] See also Figure 6 This embodiment further discloses a cooling motor temperature adjustment method. Based on the above cooling motor 100, the cooling motor temperature adjustment method includes:

[0059] S1: providing a temperature measuring element 41, the temperature measuring element 41 respectively detecting the temperatures at the air inlet 12, the air outlet 13, the stator core 26 and the stator coil; providing a specified temperature range;

[0060] S2: setting the output power of the cooling motor 100, and the central control unit transmits an initial speed signal to the speed-adjustable fan 35 according to the output power value, so that the speed-adjustable fan 35 obtains an initial speed;

[0061] S3: According to the temperature detected by the temperature measuring element 41 and the specified temperature range, the speed of the speed-adjustable fan 35 is adjusted; if the detected temperature is greater than the specified temperature range, the speed of the speed-adjustable fan 35 is increased; if the detected temperature is less than the specified temperature range, the speed of the speed-adjustable fan 35 is reduced; until the temperature detected by the temperature measuring element 41 is stable and within the specified temperature range;

[0062] S4: According to the output power and the corresponding speed of the speed-adjustable fan 35, the initial speed signal transmitted by the central control to the speed-adjustable fan 35 is corrected.

[0063] Furthermore, between step S3 and step S4, the method also includes fitting a curve of the relationship between the speed of the speed-regulating fan 35 and the temperature of the stator core 26 and the stator coil under the corresponding output power factor of the cooling motor 100, based on the temperature detected by the temperature measuring component 41 and the corresponding speed of the speed-regulating fan 35.

[0064] Through the above-mentioned cooling motor temperature control method, the initial speed signal of the speed-regulating fan 35 is continuously learned and corrected to realize the autonomous learning function. Subsequently, when the output power of the cooling motor 100 is the same, the speed of the speed-regulating fan 35 can be controlled in advance to stabilize the operating temperature of the power generation component 20 within the specified range, thereby improving the operating efficiency and heat dissipation efficiency of the motor.
