Description
Technical field
The utility model relates to a kind of good computer power that dispels the heat.
Background technology
At present, computer power all only has a radiator fan conventionally, and in computer, each electron device runs up, and while processing more and more data, often causes heat radiation not, and in computer, temperature raises.In some power supplys, adopt two radiator fans, but two fans are all with constant speed rotary, no matter are winter or summer, no matter computer is running or standby, and fan is all with fixed mode operation, does not meet energy-conserving and environment-protective, quiet requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of good computer power that dispels the heat, this power supply has two radiator fans, and can control the rotating speed of two fans and switch whether according to temperature in computer, heat radiation is good, energy saving, can reduce noise, extend the serviceable life of power supply.
The technical solution of utility model is as follows:
The good computer power that dispels the heat, comprises shell, is arranged at first fan at the shell back side, the circuit part that is arranged at the second fan above shell and is arranged at enclosure.Circuit part comprises successively connected AC input end, EMC loop, high-voltage rectifying filter circuit, power conversion transformer, DC/DC translation circuit, DC voltage output circuit.DC voltage output circuit is connected with host computer.Circuit part also comprises single-chip microcomputer, temperature sensor, and the input end of single-chip microcomputer is connected with temperature sensor, DC/DC translation circuit, and the output terminal of single-chip microcomputer is connected with the first fan, the second fan.
Beneficial effect:
The utility model good computer power that dispels the heat, has two radiator fans, temperature sensor and single-chip microcomputer, single-chip microcomputer can be controlled the rotating speed of two fans and switch whether according to temperature in computer, heat radiation well, energy saving, can reduce noise, extend the serviceable life of power supply.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the computer power that this heat sinking is good.
Embodiment
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
As shown in Figure 1, a kind of good computer power that dispels the heat, comprises shell, is arranged at first fan at the shell back side, the circuit part that is arranged at the second fan above shell and is arranged at enclosure.Circuit part comprises successively connected AC input end, EMC loop, high-voltage rectifying filter circuit, power conversion transformer, DC/DC translation circuit, DC voltage output circuit.DC voltage output circuit is connected with host computer.Circuit part also comprises single-chip microcomputer, temperature sensor, and the input end of single-chip microcomputer is connected with temperature sensor, DC/DC translation circuit, and the output terminal of single-chip microcomputer is connected with the first fan, the second fan.
The temperature that single-chip microcomputer detects according to temperature sensor, controls the rotating speed of two fans and switch whether, in summer high temperature season, allows two radiator fans all to run up, and low temperature season, only drives a radiator fan in the winter time, and to slowly run.When computer standby, two fans are also in holding state.
The utility model good computer power that dispels the heat, can control the rotating speed of two fans and switch whether according to the temperature in computer, and heat radiation is good, and energy saving, can reduce noise, the serviceable life of prolongation power supply.
