Description
Technical field
The present invention relates to a kind of heat abstractor, be specially a kind of heat abstractor for laser printer.。
Background technology
Now, print speed is than laser printer faster or adopt the photographic fixing lamp to do on the laser printer of warm-up mill radiator fan all is installed.Fixing member is to produce the maximum parts of heat in the laser printer, and the heat that fixing member produces must be discharged to the printer outside as early as possible.Too much such as the heat of hoarding in the printer, can make the polymer frame deformation in the printer, and affect the stable of printer electronic board.The purpose that radiator fan is installed on the laser printer is that the heat that fixing member produces is discharged to the printer outside.
Radiator fan on the existing laser printer is direct current ventilating fan at the uniform velocity, when printer is carried out print out task, radiator fan by constantly outwards exhausting come the heat in the printer is discharged to outside the printer.Need constantly to consume electric energy during this traditional printer radiator fan self work, and it is not intelligent, whether tape/tube printer does not need heat radiation, as long as printer is worked at the beginning, radiator fan just begins exhausting, and because the printer power supply plate provides constant voltage for it, the radiator fan uniform rotation, this has just directly caused the preheating time of printer fixing member elongated, has also increased the difficulty of printer fixing member heating roller temperature control.
Summary of the invention
The objective of the invention is the deficiency for conventional laser printer radiator fan, propose a kind of energy-conservation Intelligent heat dissipation device.This device mainly is comprised of electrothermal module, electric energy management module and ventilating fan, and electrothermal module is the electric energy input of electric energy management module, and the electric energy management module is again the ventilating fan power supply.
Wherein, electrothermal module is to utilize Seebeck effect, is thermal power transfer the assembly of electric energy, specifically integrates the sheet thermoelectric generator (TEG) that forms by a plurality of thermocouples and forms.The sheet thermoelectric generator both sides temperature difference is larger, transforms the electric energy that obtains more.During implementation, can serve as the material of making the fixing member shell with the polylith thermoelectric generator in printer, at this moment the shell of printer fixing member is exactly electrothermal module.
The electric energy management module mainly is comprised of the special chip with collection of energy function, can be divided into boost module and administration module again, is responsible for promoting input voltage, produces available horsepower, and the energy of collecting is managed.Electrothermal module is that the voltage of electric energy management module input electric energy is very low, for the mV level other, can not directly offer ventilating fan, need boost module that the voltage of input electric energy is promoted certain multiple to the V rank.Administration module be responsible for the boosting management of rear electric energy, rear voltage is compared with the minimum operating voltage of ventilating fan boosting, when the rear voltage that boosts is lower than the minimum operating voltage of ventilating fan, administration module stores pin to Energy transfer to chip and stores, when the rear voltage that boosts is higher than the minimum operating voltage of ventilating fan, administration module to ventilating fan, makes its rotation to the power delivery of boost gained electric energy and storage.
Ventilating fan is installed in an end of fixing member, belongs to speed change direct current ventilating fan, and the electric energy management module is higher for the voltage that it provides, and rotating speed is faster, is responsible for the heat that fixing member produces is discharged to the printer outside.
The heat abstractor that uses the present invention to propose, when laser printer is carried out print out task, warm-up phase at fixing member, because of the both sides temperature difference of the sheet thermoelectric generator that forms electrothermal module less, the output voltage of electrothermal module is very low, gained voltage is less than the minimum operating voltage of ventilating fan after boost module boosts, and administration module just gets up this part energy storage; When warm-up phase draws to an end, rising along with heating roller temperature, it is large that the temperature difference on sheet thermoelectric generator both sides becomes, the output voltage of electrothermal module raises, gained voltage is greater than the minimum operating voltage of ventilating fan after boost module boosts, administration module to ventilating fan, makes its rotation to the power delivery of boost gained electric energy and storage.
Can find out, at the warm-up phase of fixing member, ventilating fan does not rotate, and because the thermal loss of fixing member reduces, fixing member will be rapidly heated, and this just has been equivalent to shorten the preheating time of printer fixing member; On the other hand, when boost module boosts rear gained voltage during greater than the minimum operating voltage of ventilating fan, the fixing member temperature is higher, the temperature difference on sheet thermoelectric generator both sides is just larger, the voltage that the electric energy management module offers ventilating fan is just higher, and the rotating speed of ventilating fan is just larger, will be discharged to more heat energy the printer outside, will form so the higher heat radiation of fixing member temperature faster, so that the temperature of fixing member remains in the scope of needs automatically.
Compare with the at the uniform velocity direct current ventilating fan that the traditional heat-dissipating device adopts, the heat abstractor that the present invention proposes can be accomplished, ventilating fan does not rotate when not needing to dispel the heat, this has just shortened the preheating time of printer fixing member, the rotating speed of ventilating fan becomes large with the rising of fixing member temperature when needs dispel the heat, so that the temperature of fixing member remains in the scope of needs automatically, this has just reduced the temperature controlled difficulty of fixing member, has embodied certain intelligent.
The unnecessary heat energy that the heat abstractor that is used for laser printer proposed by the invention can utilize fixing member to produce dispels the heat for printer, so not only saved energy consumption, and shortened preheating time of printer fixing member, reduced the temperature controlled difficulty of fixing member.
