Abstract
The utility model discloses an intelligent temperature-control fan of an electric appliance, which can automatically adjust the rotating speed according to the change of the environmental temperature. A motor and a motor drive part connected in series with the motor are mounted in the fan; the input terminal of the motor drive part is connected with a CPLD central controller; the output of the CPLD central controller is connected with a temperature display; and the outputs of a temperature sensor, a toggle switch and a clock are respectively connected the input of the CPLD central controller. When the temperature of the CPLD rises, the rotating speed of the fan is increased; and when the temperature of the CPLD falls, the rotating speed of the fan is decreased. Corresponding rotating speeds can be set according to different temperatures, the fan rotates at full speed when the temperature of the CPLD reaches a certain point, and the fan stops rotating when the temperature of the CPLD reaches another certain point, therefore the heat dissipation effect is improved, the electric power consumption is reduced, and the noise generated by the high-speed rotation of the fan can be reduced. The intelligent temperature-control fan has the advantages of strong logicality, rapid response, low probability of program running-out, small volume, low cost, etc.
Description
Technical field
The utility model relates to a kind of fan, especially can adjust the fan of rotating speed according to the variation of peripheral temperature automatically.
Background technique
Fan can be used for the heat radiation and the refrigeration of equipment such as communication apparatus, stereo set, refrigerator refrigerator, household electric appliance, computer, has both improved radiating effect, has reduced power consumption again, has triple advantages of heat radiation, energy-conservation and noise reduction.Rotation speed of the fan commonly used is at present controlled by speed regulator, as required by manually-operable.Existing intelligent fan rotating speed is that single-chip microcomputer is installed in controller mostly, and its defective is: volume is big, logicality difference and response time are slow, can't satisfy the requirement of user to the fan rotational stability.
CPLD (CPLD, down together) is the higher logic component of a kind of conformability, belongs to the large-scale integrated circuit (LSI) scope, is used widely in the controller field at present.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of electrical equipment temperature control intelligent fan based on CPLD is provided, can adjusting rotation speed of the fan automatically with the variation of fan ambient temperature.
The technical solution adopted in the utility model is: be equipped with in the fan motor and with the motor driving parts of motor joining, the input end of motor driving parts connects the CPLD master controller, the output of CPLD master controller connects temperature indicator, and the output of temperature transducer, toggle switch and clock is connected the input of CPLD master controller respectively.
The beneficial effects of the utility model are:
1, can adjust rotating speed voluntarily according to system temperature, when the rising of CPLD temperature, the rotating speed of fan just improves; When the reduction of CPLD temperature, the rotating speed of fan just reduces.
2, can corresponding rotating speeds be set at different ambient temperatures, when reaching a certain temperature, the CPLD temperature just rotates at full speed, when the CPLD temperature is lower than a certain temperature, fan stops operating, so both improved radiating effect, reduce power consumption again, also reduced the noise that produces because of the fan high speed rotating.
3, can realize LCD (liquid crystal display, the down together) demonstration in real time of fan ambient temperature.
4, since the utility model based on CPLD, logicality is strong, the response time is fast so have, program is not easy to run and flies, volume is little and low cost and other advantages, overall price/performance ratio is better than existing SCM Based intelligent fan.
