Abstract
The utility model relates to a temperature rising preventing device implementing forced heat radiation of actuating system for power supplier after computer shutdown; wherein, the power supplier triggers and starts a delay switching circuit to implement the counting after the computer is shut down and simultaneously the delay switching circuit is connected with a preparation power of the power supply and delivers the power to a fan driving and control unit, and the fan driving and control unit drives a fan of the power supplier and a system fan group to run at a low speed within the time preset by the delay switching circuit and synchronously displays the working state of the fan of the power supplier and the system fan group. In view of the characteristics, the delay switching circuit continues to drive the fan of the power supplier and the system fan group after the computer is shut down to run for a period of time to continuously implement the forced heat radiation of the power supplier and the system so as to effectively solve the problem that the internal integrated circuits and the electronic elements of the computer generate the accumulated heat and temperature-rise effect when the computer is suddenly shut down, thus preventing the phenomenon of the temperature rising.
Description
Technical field
The utility model relates to the temperature rising preventing device of a kind of computer shutdown by power supply unit actuating system forced heat radiation, mainly be behind computer shutdown, continue drive fan running a period of time by delayed switching circuit, continue power supply unit and system's forced heat radiation, suddenly close with effective solution computing machine, long-pending heat and temperature-rise effect that its internal integrated circuit and electronic component produced, and then prevent the phenomenon of rising again.
Background technology
Because the progress of science and technology, progressing greatly of integrated circuit and various electronic component processing procedures, make the also beneficial shape of speed of interior computing of unit interval and processing quick, the relative heat that makes generation constantly increases (for example: it is right that the working temperature of existing Pentium series is about 60 degree friends Celsius, and the working temperature of AMD K7 series is more up to 80 degree Celsius); Again in order to satisfy aforementioned integrated circuit (CPU) and to drive its interior arrangement (as: light; disk drive promptly is) running demand; this power supply unit must provide higher power output; especially bad; every device processing speed at computing machine is increased sharply; the heat that is produced also improves relatively; it dispels the heat and (presses so must install more fan; the power source of fan is still by power supply unit); therefore for the need for electricity of load is provided before providing; make this power supply supply raise and to keep work under the high power output mode; cause cause this in order to the electronic component of step-down rectifier (as commutator; voltage devices etc.) thermal value heightens; only when computer operating; the commutator of this integrated circuit (CPU) and electronic component and power supply unit; transformer etc.; can reach radiating effect by its default fan blows; yet computing machine is when user's shutdown (SoftQff); this fan is cut off power supply simultaneously and shuts down; also stop simultaneously blowing of wind-force; because this integrated circuit and electronic component and commutator; transformer etc.; its general working temperature is promptly quite high; when fan stops suddenly; its remaining heat closes because of not being subjected to wind-force to blow accumulation gradually; make its sudden temperature rise; the often paranormal working temperature of its temperature and lasting one section long time; promptly produce the so-called phenomenon of rising again; in this time in stage; regular meeting causes the damage of integrated circuit or aforementioned every electronic component or influences the serviceable life of system, therefore truly has necessity of being improved.
The utility model content
Fundamental purpose of the present utility model, be to provide the temperature rising preventing device of a kind of computer shutdown by power supply unit actuating system forced heat radiation, behind computer shutdown, trigger the startup delayed switching circuit by power supply unit, utilize delayed switching circuit to connect to draw the pre-stand-by power source of power supply unit, and continue lasting microrunning a period of time of drive fan, and continue power supply unit and system's forced heat radiation, with effective solution integrated circuit and commutator, the long-pending heat and the temperature-rise effect of each electronic component such as transformer, and the infringement of the computer system that phenomenon causes that prevents to rise again.
Secondary objective of the present utility model, be to provide the temperature rising preventing device of a kind of computer shutdown by power supply unit actuating system forced heat radiation, the external time schedule controller of this delayed switching circuit nationality one wherein, and adopt the gate time that the mode of manually alloting is set its time-delay switch unit by the user, the duty of mat display display delayed switch unit has easy-to-use effect simple in structure simultaneously.
