Abstract
The utility model relates to the control technical field, in particular to a control device of cooling fans inside a computer case. The utility model is composed of a LED, a control chip, a temperature probe and a switch key; the control chip is respectively connected with the LED, the temperature probe that extending into the computer case, the switch key and the cooling fans inside the computer case. With such a structure, the control chip can control the make-and-break of the cooling fans inside the computer case and the number of the working cooling fans according to the actual temperature inside the case detected by the temperature probe, with the controlling results being displayed on the screen of the LED, thus the utility model can save power and is convenient to be operated.
Description
Technical field:
The utility model relates to the control technology field, refers in particular to the control device of radiator fan in a kind of computer housing.
Background technology:
Computer in use can produce heat in its cabinet, as can not in time dispelling the heat, will badly influence the performance of machine.Therefore the case radiation problem is the problem that computer manufacturer must think better of all the time.For addressing this problem, be provided with some several radiator fans in the present computer housing, these radiator fans are action together along with machine startup, but computer is along with the length difference of service time, temperature in its cabinet also is different, if service time is shorter, temperature in the cabinet can be too not high, do not need the radiator fan in the cabinet all to move, even do not need radiator fan, this shows that the control mode of radiator fan is not quite reasonable in the existing computer housing.
Summary of the invention:
The purpose of this utility model just is to provide at the deficiencies in the prior art part a kind of control device that can detect temperature in the computer housing automatically and correspondingly control the switch of radiator fan.
The utility model is achieved by the following technical solution: it is made up of LCD, control chip, temp probe and on ﹠ off switch, and control chip is connected with LCD, the radiator fan that stretches in temp probe, on ﹠ off switch and the computer housing in the computer housing respectively.
By above-mentioned structure, whether and open what fans and all can be controlled and be presented at by control chip on the display screen of LCD according to the actual temperature in the detected cabinet of temp probe the switch of the radiator fan in the computer housing, saves energy effectively, and use very convenient.
Description of drawings:
Accompanying drawing 1 is circuit theory diagrams of the present utility model
See shown in the accompanying drawing 1, the utility model includes: LCD 1, control chip 2, temp probe and on ﹠ off switch, control chip 2 are connected with LCD 1, radiator fan F1, the F2, the F3 that stretch in temp probe 3, on ﹠ off switch 4,5 and the computer housing in the computer housing respectively;
The model of control chip 2 is EM78P156ELP;
LCD 1 links to each other by the 2nd, 6,7 pin of data line and control chip 2, the 1st pin of temp probe 3 and control chip 2 links to each other, the 12nd pin of on ﹠ off switch 4 control chips 2 links to each other, on ﹠ off switch 5 links to each other with the 3rd, 5,13 of the data line of LCD and control chip respectively, and three radiator fan F1, F2, F3 in the computer housing link to each other with the 9th, 10,11 pin respectively.
Embodiment:
The utility model in use, when temp probe 3 detect in the cabinet temperature when being higher than 15 degrees centigrade, the 9th pin of control chip 2 output 5V high level, first starting fan in the cabinet shows FAN1/ON on the display screen of LCD 1 simultaneously;
When detect when temp probe 3 in the cabinet temperature when being higher than 30 degrees centigrade, the 10th pin of control chip 2 output 5V high level, second starting fan in the cabinet shows FAN2/ON on the display screen of LCD 1 simultaneously;
When temp probe 3 detect in the cabinet temperature when being higher than 45 degrees centigrade, the 9th pin of control chip 2 output 5V high level, the 3rd starting fan in the cabinet shows FAN3/ON on the display screen of LCD 1 simultaneously;
And when temp probe 3 detect in the cabinet temperature below 15 degrees centigrade the time, the 9th, the 10th pin of control chip 2 and the 11st pin are all exported the 0V low level, cabinet internal fan Close All;
The effect of on ﹠ off switch 4 is: when it was pressed, the 9th, the 10th pin and the 11st pin of control chip 2 were all exported the 5V high level, simultaneously, the backlight of LCD 1 is shinny, behind trip switch slurry 4, the 9th, the 10th pin of control chip 2 and the 11st pin recover operate as normal, and backlight does not work;
The effect of on ﹠ off switch 5 is: when pressing on ﹠ off switch 5, the backlight of LCD 1 is shinny, and behind trip switch key 5, backlight still can continue bright 5 times in second.
