The motor comprises a stator and a rotation shaft which is fixedly connected with the fan blades, and the rotation shaft can be inserted in the stator of the motor. The refrigeration unit comprises an electronic refrigerator and a refrigeration pipe. A ventilation groove surrounding the fan blades is opened in the outer edge of the outer frame, and the refrigeration pipe is arranged in the ventilation groove. By means of the refrigerant direct-current fan, the temperature in the refrigeration pipe is reduced due to the refrigeration unit, so that the temperature of air around the refrigeration pipe is reduced, cold air can be sent out when the fan blades rotate, the cold air flowing is increased on the basis of air flowing cooling added on an original fan to take away heat, and a good cooling effect can be achieved.
Description
Technical field
The utility model relates to a kind of fan radiator, and especially a kind of fan radiator with refrigeration, belongs to radiating device technical field.
Background technique
Along with developing rapidly of computer technology, at present computer has been popularized and has been applied, for existing computer, and notebook computer especially, the quality of heat radiation is the principal element that affects the computer life-span.Common computer cooling machine cabinet is all that fan rotates to cooling machine cabinet with common radiation fan, so most radiating effect all approaches.If such radiating efficiency is used in rack ultra-thin or MINI the inside, just cannot play radiating effect rapidly, can make like this computer life-span be subject to loss.
Model utility content
The utility model 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, DC fan of freezing described in the utility model, comprise power supply, the fan body being 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, or thermoelectric cooling, it is the subject between refrigeration technology and semiconductor technology edge growing 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 reduces the temperature in refrigerator pipes, so just reduced the temperature of refrigerator pipes surrounding atmosphere, when electric fan rotates, cool air can be sent, at original fan, increase Air Flow 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, is evenly arranged in ventilation slot.
The work running of semiconductor refrigerating sheet is with direct current (d.c.), it not only can freeze but also can heat, by changing the polarity of direct current (d.c.), decide realization refrigeration or heating on same refrigerating sheet, 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 time, in this circuit, connect after direct current (d.c.), the just energy-producing transfer of energy, the joint that electric current flows to P type element by N-type element absorbs heat, become cold junction and by P type element, flowed to the joint release heat of N-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 technology application:
1, without any need for refrigeration agent, can continuous operation, do not have pollution sources there is no rotary component, can not produce gyroscopic action, there is no slide member is a kind of solid piece part, does not have vibrations, noise, life-span long during work, 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, is forever 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 and control, and adds temperature measurement and control means, is easy to realize remote control, program control, computer control, is convenient to form automatic control system.
4, semiconductor refrigerating sheet thermal inertia is very little, and the cooling and heating time is very fast, and the in the situation that of 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 is generally applicable to the generating of middle low temperature area.
6, the right power of the single cooling module of semiconductor refrigerating sheet is very little, but be combined into pile, with the Combination of Methods of pile series and parallel of the same type, become refrigeration system, it is very large that power just can be done, so refrigeration work consumption can accomplish that several milliwatts are to the scope of upper myriawatt.
7, the temperature range of semiconductor refrigerating sheet, can realize to 130 ℃ of negative temperatures from 90 ℃ of positive temperature.
DC fan of freezing described in the utility model, has better radiating effect, can be applied in less thinner rack, is equally applicable to various radiation fans.
