Description
Technical field
The utility model relates to a kind of controller for heat sink, relates in particular to a kind of controller for heat sink that is used for display.
Background technology
At present, people are extensive use of various displays, as computer monitor, glass bulb TV etc.Because radiating effect is bad, occurs the situation that display damages because of working temperature is too high easily, influences the useful life of display.
The utility model content
The purpose of this utility model provides a kind of controller for heat sink that is used for display, can strengthen the display radiating effect, prolongs display useful life.
The utility model adopts following technical proposals:
A kind of display controller for heat sink, comprise the control unit and first fan, described control unit comprises processor, relay, temperature sensor, button inputting circuits and power module, temperature sensor is installed in display interior, the temperature acquisition signal input part of the signal output part connection processing device of temperature sensor, the signal input end of the signal output part connection processing device of button inputting circuits, powering on of the control signal output ends control relay coil of processor, the power input of power module connection processing device, first end of relay normally open contact connects power module, and second end of relay normally open contact connects the power input of first fan.
Described control unit also comprises display module, the shows signal output of the signal input part connection processing device of display module.
Also comprise the time-delay cooling module, described time-delay cooling module comprises the delay circuit and second fan, and the power input of delay circuit connects second end of relay normally open contact, and the signal output part of delay circuit connects second fan.
Also comprise alarm, described alarm signal input part connects the signal output part of delay circuit.
The utility model is simple and practical, is easy to realize, can effectively reduce the display interior temperature, improves display useful life.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises power module, button inputting circuits, display module, processor, temperature sensor, relay, first fan, second fan, delay circuit and alarm, temperature sensor is installed in display interior, the temperature signal input of the signal output part connection processing device of temperature sensor, the signal input end of the signal output part connection processing device of button inputting circuits, the control signal output ends control relay coil J of processor powers on, the power input of power module connection processing device, power module is connected with the power input of first fan and the power input of delay circuit respectively by the normally opened contact J1 of relay, and the signal output part of delay circuit is connected with the power input of second fan and the power input of alarm respectively.
When the user uses the utility model, can set the safe handling temperature by button inputting circuits, when the display interior temperature high during to the temperature sensor temperature threshold set, processor sends control signal, relay coil J gets, the normally opened contact J1 closure of relay, first fan must be established beginning work by cable, and display interior is carried out radiating and cooling; In the first fan work process, when the display interior temperature was lower than the temperature sensor temperature threshold of setting, processor did not send control signal, relay coil J outage, and the normally opened contact J1 of relay disconnects, and first fan is de-energized and quits work.
During first fan work, if the display interior temperature still is higher than the temperature sensor temperature threshold of setting, the normally opened contact J1 of relay still is in closure state, arrive the time of delay circuit setting when the first fan work time after, second fan and alarm simultaneously electric work, second fan running is strengthened radiating effect, alarm sends alarm signal simultaneously, prompting user display temperature anomaly avoids that display temperature is too high to influence useful life.
Delay circuit is an existing products in markets, is not giving unnecessary details at this.
The power supply of first fan and second fan can use the display interior power supply, also can use external power supply.
The utility model can be installed in display casing left side, right side or upside louvre place, also can be installed on display casing inside.This device is equally applicable to various computer monitors and glass bulb TV, also can be used for domestic television set.The utility model can effectively reduce the display interior temperature, and is simple and practical, is easy to realize, can prolong display useful life.
