Add, the power consumption of notebook is also increasing, and the stand-by time that how to prolong when breaking away from electrical network has also become a very important problem.When breaking away from electrical network, notebook relies on powered battery to come work, but battery is a kind of expendable equipment, and along with service time and the increase that discharges and recharges number of times, the electric weight that can store after battery once is full of reduces, and stand-by time also just reduces.Usually, all be to solve this problem in the mode of changing battery, still, the battery price is again relatively very expensive, this has just brought many troubles to the user.
Summary of the invention
The purpose of this invention is to provide a kind of notebook cooling system, this system can also utilize heat energy to generate electricity to notebook in to the notebook heat radiation.
In order to achieve the above object, technical scheme of the present invention has provided a kind of notebook temperature insurance system based on thermo-electric generation, it is characterized in that, comprising:
Temperature difference electricity generation device: temperature difference electricity generation device links to each other each thermal source in the notebook with the notebook radiator fan, and temperature difference electricity generation device utilizes the temperature difference to produce electric energy;
The voltage stabilizing rectification circuit: the input end of voltage stabilizing rectification circuit connects temperature difference electricity generation device, and output terminal connects the battery in the notebook or is powered device, and the stable electric energy by temperature difference electricity generation device output of voltage stabilizing rectification circuit is so that power supply or output voltage stabilization;
The first cold wind isocon: the first cold wind isocon links to each other the notebook radiator fan with temperature difference electricity generation device, and the cold wind that the notebook radiator fan is produced is sent in the second cold wind isocon in the temperature difference electricity generation device.
The present invention has utilized thermo-electric generation, the heat of part in the notebook is converted into electric energy utilizes again.This method both can have been accelerated heat radiation, can recycle energy again, made the time of notebook standby when breaking away from electrical network longer.The present invention is improved on the basis of traditional heat-dissipating, and thermo-electric generation and traditional heat radiation are worked simultaneously, make cooling system more effective like this.Circuit part of the present invention can be integrated on the mainboard, and it is little to take up room; Secondly, therefore total system can not increase any noise to notebook owing to do not have fan.

Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
Embodiment
As shown in Figure 1, be a kind of notebook temperature insurance system provided by the invention based on thermo-electric generation, comprise: temperature difference electricity generation device 1: temperature difference electricity generation device links to each other each thermal source 4 in the notebook with notebook radiator fan 5, and temperature difference electricity generation device utilizes the temperature difference to produce electric energy; The voltage stabilizing rectification circuit: the input end of voltage stabilizing rectification circuit connects temperature difference electricity generation device, output terminal connects the battery in the notebook or is powered device by holding circuit, the stable electric energy by temperature difference electricity generation device output of voltage stabilizing rectification circuit is so that power supply or output voltage stabilization; Holding circuit: holding circuit is connected the battery in voltage stabilizing rectification circuit and the notebook or is powered between the device, holding circuit provides the defencive function that is powered between device, other power supplys of notebook and the native system, prevents phase mutual interference and electric leakage between them; 2: the first cold wind isocons of the first cold wind isocon link to each other notebook radiator fan 5 with temperature difference electricity generation device, the cold wind that notebook radiator fan 5 is produced is sent in the second cold wind isocon 7 in the temperature difference electricity generation device; On voltage stabilizing rectification circuit and holding circuit, be connected with BIOS and support device.
As shown in Figure 2, temperature difference electricity generation device 1 comprises thermoelectric generator 8, heat pipe 6 and is wrapped in the heat pipe 6 second cold wind isocon 7 outward.Wherein, thermoelectric generator 8 is between the heat pipe 6 and the second cold wind isocon 7.Thermoelectric generator 8 is made up of cold junction and hot junction, and the cold junction place has the second cold wind isocon 7 that heat radiation is provided, and makes cold junction be in low-temperature condition with respect to the hot junction, and each interior thermal source 4 of place, hot junction and notebook is connected by heat pipe 6 indirect cover types.Thermal source 4 distributes along temperature difference electricity generation device 1, and the thermoelectric generator 8 and the second cold wind isocon 7 are not set between thermal source 4 place's heat pipes 6 and thermal source 4, but will connect by conducting strip 3.The outside surface of described heat pipe 6 is close in the hot junction, or is embedded in the outside surface of described heat pipe 6.
The first cold wind isocon 2 distributes cold wind from notebook radiator fan 5 and sends in the second cold wind isocon 7, takes away the heat of thermoelectric generator 8 cold junctions, makes the cold junction of thermoelectric generator 8 be in lower temperature; The heat that gives out from each thermal source 4 is collected via conducting strip 3 and heat pipe 6, is delivered to the hot junction of thermoelectric generator 8, makes the hot junction not stop to such an extent that be in the higher temperature state.Like this, just have temperature gap between the cold junction of thermoelectric generator 8 and the hot junction, temperature gap makes between cold junction and the hot junction and produces electromotive force, and heat is converted into electric energy, produces the effect of cooling, insulation and energy recovery.
When notebook was started shooting, its BIOS began detection hardware.Whether the BIOS of native system supports that device detects voltage stabilizing rectification circuit and holding circuit can operate as normal; if which module does not have operate as normal, BIOS receives the abnormal signal of hardware, and notebook gives the alarm; the prompting hardware problem needs the user to carry out certain operation.When detecting just often, native system brings into operation.
After the start, the 4 beginning evolutions of heat of thermals source such as CPU, video card, north and south bridge, the heat temperature that heat pipe 6 is collected these thermals source 4 rises, and is heated up in the hot junction of thermoelectric generator 8.At this moment notebook radiator fan 5 operations pass the heat of coming with air outlet place heat pipe 6 and blow out notebook.Meanwhile, the cold wind of notebook radiator fan 5 is taken away the heat of thermoelectric generator 8 cold junctions by the first cold wind isocon 2 and the second cold wind isocon 7, gives cold-side cooling.Produce the temperature difference between the hot junction of thermoelectric generator 8 and the cold junction, thermoelectric generator 8 absorbs heat energy, and is electric energy with thermal power transfer.
