See also No. the 435721st, TaiWan, China patent announcement " fan control device ", this case is that temp-sensitive apparatus is when recording reality or ambient operating temperature and being lower than setting temperature, then control IC and promptly drive accessory circuit, less power supply supply fan is provided, make fan continue rotating speed with about 1/3; And when reality or ambient operating temperature are higher than setting temperature, then control the accessory circuit that IC promptly drives general step-down and control, and full power supply supply fan is provided, make fan do rotating speed at full speed.
But, will there be shortcoming in this accessory circuit, if when reducing to less power supply supply fan by full power supply supply fan situation, will produce power dissipation and heating when step-down, and empty gain of heat amount will make circuit will make the impedance increase easily make control IC and inner body damage.
Please refer to TaiWan, China patent announcement M255636 number " fan control device " again, when this case does not reach the setting temperature of fan running when work or ambient temperature, fan will not turn round, and when work or ambient temperature reach fan running setting temperature, be the drive fan running, it mainly is to carry out work of detection and examination or ambient temperature by thermistor.
There is a little shortcoming in this same case, be working state when being not high load condition, this fan will not turn round, perhaps whether the user will damage by this fan of misidentification, also maybe this device allows temperature be in the relatively-high temperature under a kind of preset temperature and does not start regular, the heat that accumulates will make the impedance increase of circuit and electrical assembly that inner body is damaged, and reduces working life.
The model utility content
The purpose of this utility model is to disclose a kind of two voltage input intelligent temperature control fan circuit devices of computer supply supply, this circuit arrangement provides the result with temperature detecting to produce the power change that gives fan, under the different loads situation, give suitable radiating effect, so, see through this circuit arrangement and can reduce the virtual work loss, in order to raising the efficiency, meet energy saving policy.
Another purpose of the present utility model is to disclose a kind of two voltage input intelligent temperature control fan circuit devices of computer supply supply, this circuit arrangement can produce suitable running at the following fan that makes of different load temperatures, exempt fan and continue to keep the state that runs up, can prolong the life-span that fan uses.
Another purpose of the present utility model is to disclose a kind of two voltage input intelligent temperature control fan circuit devices of computer supply supply, and when utilization low voltage drive fan, the running noise that fan produced is lower.
In a specific embodiment, two voltage input intelligent temperature control fan circuit devices of computer supply supply of the present utility model are made up of to drive a fan a control module circuit, the first power voltage supply module, the second power voltage supply module and temperature detecting device; Wherein, when temperature detecting is installed on detection area scope detecting when being first state, allow the first power voltage supply module that fan is powered by the control module circuit, this fan is a rotational speed under first state to meet the detection area scope; When temperature detecting is installed on detection area scope detecting when being second state, switch to the second power voltage supply module by the control module circuit fan is powered, this fan is a rotational speed under second state to meet the detection area scope.
Wherein, this first power voltage supply module is the 5V powering mode, can provide via the power supply unit in the computer main; This second power voltage supply module is the 12V powering mode, also provides via the power supply unit in the computer main.
Has one group of changeover module switch in this control module circuit, the electronic switch assembly that is generally transistor-like constitutes, see through the temperature detecting device to meeting detection area scope ambient temperature sensing, for example: spend for separating with degree centigrade 80, when temperature is higher than degree centigrade 80 degree, to start fan with the 12V powering mode, fan running faster; When temperature is lower than degree centigrade 80 degree, will start fan with the 5V powering mode, fan running is more at a slow speed.
In addition, this temperature detecting device can be many groups, is laid in the position of different desires detecting temperature respectively, via whole weighted calculation or in wherein analysis modes such as a temperature Gao Zhe, signal is delivered to the control module circuit, select different voltages to offer fan by the control module circuit again.
Can be further understood by following creation detailed description and accompanying drawing about advantage of the present utility model and spirit.
