Through the design, the temperature in the refrigerating pipes is lowered due to the adoption of the refrigerating device, so that the temperature of air around the refrigerating pipes is lowered, when the fan blade rotates, cold air can be sent out, in such a way, the flow of the cold air is increased for directly taking away heat on the original basis that the fan accelerates the air flow for radiating, so that a better radiating effect is realized.
Description
Technical field
The present patent application relates to a kind of fan radiator, and especially a kind of fan radiator with refrigeration, belong to radiating device technical field.
Background technique
Along with developing rapidly of computer technology, at present computer is popularized and is applied, for existing computer, and notebook computer especially, the quality of heat radiation is the principal element that affects the computer life-span.The common computer cooling machine cabinet is all that fan rotates to cooling machine cabinet with common radiation fan, so most radiating effect all approaches.Just can't play radiating effect rapidly if such radiating efficiency is used in rack ultra-thin or MI NI the inside, can make like this computer life-span be subject to loss.
Summary of the invention
The present patent application is for the existing above-mentioned deficiency of current computer radiator, and a kind of radiation fan that is provided with refrigeration plant is provided.
Specifically, the described DC fan of freezing of the present patent application, comprise power supply, the fan body be connected with power supply and refrigeration plant, fan body comprises housing and is positioned at the support of housing, mid-stent is provided with circuit board and motor and electric fan, motor comprises stator and rotating shaft, rotating shaft is fixedly connected with electric fan, rotating shaft can be inserted in the stator of motor, refrigeration plant comprises electronic refrigerator and refrigerator pipes, inner edge at housing has the ventilation slot around electric fan, and refrigerator pipes is positioned at ventilation slot.
Further, described electronic refrigerator comprises semiconductor refrigerating sheet, is attached to the housing of fan body, and number is more than four.
Electronic refrigerating claims again semiconductor refrigeration, perhaps thermoelectric cooling, it is the subject between refrigeration technology and semiconductor technology edge grown up, the P-N knot that it utilizes extraordinary semi-conducting material to form, form thermocouple pair, produce peltier effect, a kind of New Refrigerating method of freezing by direct current, with compression-type refrigeration and absorption refrigeration and be called the large refrigeration modes in the world three.
Such design, refrigeration plant work makes the temperature in refrigerator pipes reduce, so just reduced the temperature of refrigerator pipes surrounding atmosphere, when electric fan rotates, cool air can be sent, increase Air Flow at original fan like this and fall on hot basis, increased flow of cold air and directly taken away heat, can reach better radiating effect.And electronic refrigerating does not need other circuit.
Further, described refrigerator pipes is round metal tube, is positioned at ventilation slot and distributes around electric fan.
Further, the number of described refrigerator pipes is more than one, evenly is arranged in ventilation slot.
The work running of semiconductor refrigerating sheet is to use direct current (d.c.), it not only can freeze but also can heat, decide and realize refrigeration or heating on same refrigerating sheet by the polarity that changes direct current (d.c.), the generation of this effect is exactly the principle by thermoelectricity, the working principle of semiconductor refrigerating sheet is: when a N-type semiconductor material and P-type semiconductor material be coupled to galvanic couple to the time, connect direct current (d.c.) in this circuit after, the just energy-producing transfer of energy, the joint that electric current flows to P type element by the N-type element absorbs heat, become cold junction and flowed to the joint release heat of N-type element by P type element, become hot junction.The size of heat absorption and release is that the element logarithm by the size of electric current and semi-conducting material N, P decides.Refrigerating sheet inside is by the thermopiles that galvanic couple is unified into up to a hundred (as right figure), to reach the effect that strengthens refrigeration (heating).
Semiconductor refrigerating sheet, as extraordinary low-temperature receiver, has following advantage and disadvantage in the technology application:
1, without any need for refrigeration agent, but continuous operation does not have pollution sources there is no rotary component, can not produce gyroscopic action, and there is no slide member is a kind of solid piece part, during work, does not have vibrations, noise, life-span long, installs easily.
2, semiconductor refrigerating sheet has two kinds of functions, can freeze, and can heat again, and refrigerating efficiency is generally not high, but heating efficiency is very high, forever is greater than 1.Therefore use a sheet part just can replace discrete heating system and refrigeration system.
3, semiconductor refrigerating sheet is electric current transducing matrix part, by the control of input current, can realize high-precision temperature control, adds the temperature measurement and control means, is easy to realize remote control, program control, computer control, is convenient to form automatic control system.
4, the semiconductor refrigerating sheet thermal inertia is very little, and the cooling and heating time is very fast, in the situation that the good cold junction zero load of hot-side heat dissipation, energising was less than one minute, and refrigerating sheet just can reach maximum temperature difference.
5, the reverse use of semiconductor refrigerating sheet is exactly thermo-electric generation, and semiconductor refrigerating sheet generally is applicable to middle low temperature area generating.
6, the right power of the single cooling module of semiconductor refrigerating sheet is very little, but be combined into pile, become refrigeration system with the Combination of Methods of pile series and parallel of the same type, it is very large that power just can be done, so refrigeration work consumption can be accomplished the scope of several milliwatts to upper myriawatt.
7, the temperature range of semiconductor refrigerating sheet, can realize to 130 ℃ of negative temperatures from 90 ℃ of positive temperature.
The described DC fan of freezing of the present patent application, have better radiating effect, can be applied in less thinner rack, is equally applicable to various radiation fans.
