Accompanying drawing explanation
Fig. 1 is the electrical block diagram of Chip-R of the present invention in printed circuit board (PCB);
Fig. 2 is FB(flow block) of the present invention.
Embodiment
Below, with reference to drawings and Examples, the present invention is described in detail:
As shown in Figure 1, the present invention adopts Chip-R 2512 to be packaged into heating unit based on the Chip-R in 75 Europe, again by the heating unit of series connection two 75 Europe Chip-Rs as 1W, the power supply of each heating unit is 12V, each ohmically rated power is 0.5W, by the heating unit of the multiple 1W of parallel connection, according to actual heating effect, can infinitely go to increase heating power.
Due to Chip-R heating in heating unit, Chip-R is at PCB(printed circuit board, printed circuit board (PCB)) in layout to consider sufficient area of dissipation, simultaneously the Copper Foil of PCB is also good heat dissipation vehicle, PCB preferably independent one piece of platelet of heat patch resistance.
As shown in Figure 2, the method for controlling internal temp of hard disc recording equipment of the present invention, is specially:
I when the sensor of hard disc recording device interior detects that environment temperature is under hard disk operational temperature, and sensor record environment temperature is at that time initial value, and controller controls Chip-R and starts working, and sensor testing environment temperature per second;
II works as sensors sense environmental temperature is greater than working temperature, and the Chip-R working time is when reaching the heat time, controller starts hard disk and the system of hard disc recording device interior, if environment temperature is not greater than working temperature, or not reaching the heat time, Chip-R works on;
III when after the hard disk and system startup of hard disc recording device interior, and Chip-R works on;
IV when sensors sense environmental temperature is greater than temperature hysteresis, and controller controls Chip-R and quits work, if environment temperature is not greater than temperature hysteresis, Chip-R works on.
Environment temperature in described hard disc recording equipment is subzero less than 40 DEG C time, and Chip-R is started working.
In described hard disc recording equipment, the working temperature of hard disk is 0 DEG C.
The heat time of described Chip-R is from Chip-R is started working, the time used when equaling working temperature to environment temperature.
Temperature hysteresis in described hard disc recording equipment is 10 DEG C.
In actual use, also need to consider warm area and temperature rising curve, because temperature is dispelled the heat to device interior heating by air, near the place that Chip-R is near, temperature rises can be very fast; The position of sensor is also important, should as far as possible away from heating plate, because the magnetic head of hard disk is at hard drive internal, heating hard disk heats mainly to its magnetic head assembly, harddisk surface and internal temperature balance needs process.What detect due to sensor is the real time temperature of a point, and harddisk surface temperature-rise ratio inside wants fast, so there is a delayed process.
When cold-starting heating, controller will in conjunction with current detection to temperature spot and the temperature rising curve of hard drive internal carry out synthetic determination, whether met the temperature requirement of hard disk startup.Temperature rising curve is obtained by actual measurement, is converted into time point one by one.Time low temperature cold opens, controller binding time point, as with reference to foundation, estimates the actual temperature of hard drive internal in conjunction with real time temperature, meet and start requirement, start to hard disk and system power-up, temperature starts not, can cause disk cannot carry, reduced lifespan, even damages.
During cold operation, same because hard drive internal temperature declines and also has a delayed process, so sensor can first detect that temperature is too low, as long as so detect that real time temperature goes heating just passable by sensor.But in cold operation, the process that temperature rises, close Chip-R need one delayed, such as can be heated to 10 DEG C more than and stop heating again, instead of temperature just stops immediately to 0 DEG C.
