Detailed Description
The invention is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.
Example 1: referring to fig. 1, the present invention provides a technical solution: a heat dissipating cabinet, comprising: the device comprises a cabinet, a controller 1, a connecting button 2, a fan 3, a motor 4, a plurality of temperature sensors 6 and a setting unit 7, wherein the connecting button is fixed on a belt 5, the belt 5 is connected with the motor, and the fan is clamped on the connecting button to adjust the direction; the temperature sensors are discretely distributed in the cabinet, and the controller, the fan, the motor, the temperature sensors and the setting unit are electrically connected; the setting unit dynamically sets the working mode and the working temperature of the fan.
The cabinet is characterized in that a plurality of heat dissipation holes are formed in the peripheral side wall of the cabinet to ensure cold and hot air circulation, the controller is a single-chip microcomputer, the controller is simple in function, only obtains the temperature value of a temperature sensor, and controls a stepping motor to move to a corresponding position according to the temperature value to control basic functions such as the rotating speed of an electric fan, so that a mature 51-series single-chip microcomputer or a stm 32-series single-chip microcomputer is selected in the embodiment, the motor is a stepping motor, accurate positioning is realized, no special requirement exists, and the model 86BYG250A is selected in the embodiment; the setting unit is connected with a display screen, and the model of the display screen used in the example without special requirements is 12864-B.
The innovation point of the invention is mainly that on the setting unit, the working temperature of the fan can be dynamically set, the temperature of the fan at the lowest rotating speed and the temperature of the fan at the highest rotating speed are respectively set, the display screen simultaneously displays numerical values, for example, the temperature of the fan is set to be 70 degrees corresponding to the highest speed of the fan, the temperature of the fan is set to be 25 degrees corresponding to the lowest speed of the fan, and the temperature change between the fan rotating speeds is adjusted to realize a linear relation by controlling voltage.
When the fan is in operation, the direction of the fan is adjusted according to actual needs and is suitable for different positions of a device to be cooled, and then the working modes are set according to the needs, wherein the fan comprises two working modes: the temperature sensor is in a temperature difference working mode and a highest temperature mode.
The temperature sensor temperature difference working mode means that the difference between the highest temperature and the lowest temperature among the plurality of temperature sensors reaches a specified value, the specified value is dynamically set by the setting unit, for example, the temperature difference is set to 10 ℃, and when the temperature difference between the highest temperature sensor and the lowest temperature sensor reaches the specified value, the controller starts the stepping motor to move the fan to the highest temperature area for heat dissipation.
The highest temperature mode is that the stepping motor moves the fan to the position of the sensor with the highest temperature, and the stepping motor moves along with the temperature change when the fan is used. For example, the highest temperature in the plurality of sensors is 60 ℃, the controller controls the stepping motor to move the fan to the position of the highest temperature sensor for heat dissipation, and when the temperature of the temperature sensor at the position is reduced in the heat dissipation process and the values of the temperature sensors at other positions become maximum, the controller starts the stepping motor to drive the fan to move to the corresponding position for heat dissipation. The scaling factor of the fan speed is: the current temperature minus the temperature corresponding to the lowest fan speed set on the temperature ratio corresponding to the highest fan speed minus the temperature corresponding to the lowest fan speed set, in this example, the scale factor is (60-25)/(70-25), and the highest operating voltage of the fan is multiplied by the scale factor to obtain the operating voltage of the fan, thereby controlling the speed. The current temperature is 70 ℃ or higher, and the scale factor is 1.
