Abstract
The invention discloses a table-type high-speed centrifugal machine, which comprises a motor, a rotor, a centrifugal cavity and a door cover, wherein the inner side face of the door cover is provided with at least one air ducting device, the door cover is provided with an air outlet and an interembeded air duct. One end of the interbedded air duct is connected with the air ducting device and the other end of the interbedded air duct is connected with the air outlet. The centrifugal machine has the advantages of ventilation and cooling by using the operational characteristics of the centrifugal rotor, simple structure, great reduction of manufacturing and operational cost and lower noise level. The centrifugal machine can achieve better cooling and radiation effect as well as low-noise effect with a self air duct structure instead of a complex and expensive compressor or semi-conductor cooling system and a cooling fan.
Description
Technical field
The present invention relates to a kind of table model high speed centrifuge, relate in particular to a kind of table model high speed centrifuge with low noise cooling structure.
Background technology
In general, table model high speed centrifuge basic structure drives carrying by high-speed electric expreess locomotive and treats that the rotor of centrifuged sample test tube carries out rotation at a high speed and forms in the centrifugal chamber of relative closure.In this process; Drive motors can produce great amount of heat when high-speed cruising; And rotor in running also can because of with centrifugal chamber in windage and produce heat, these heats can make the temperature of air and rotor in the centrifugal chamber rise, and raise thereby make by centrifugal invisible spectro sample temperature; It is not only unfavorable to centrifuge itself that temperature continues to raise, and more can have influence on thermally sensitive specimen.
And existing solution is by compressor refrigeration system or semiconductor refrigerating piece frozen cooling to be carried out in centrifugal chamber; Initiatively cooling fan is lowered the temperature to motor; Though good cooling results, manufacturing cost and operating cost are all very high, for some waste of the sample that does not need accurate constant temperature.
And common non-freezing type is to rely on the centrifugal chamber means such as perforate to carry out the air draft cooling, and not only cooling effect is undesirable, and the noise of wind is huge.
Summary of the invention
The objective of the invention is to propose a kind of table model high speed centrifuge of low noise cooling structure, both possessed good low noise effect, the cooling heat dissipation effect is arranged again.
For achieving the above object, the present invention takes following technical scheme:
A kind of table model high speed centrifuge; Comprise motor, rotor, centrifugal chamber, door closure; Said door closure medial surface is provided with at least one air ducting, and said door closure also is provided with air outlet, and said door closure also is provided with the interlayer air channel; One end in said interlayer air channel is connected with air ducting, and the other end is connected with said air outlet.The motor-driven rotor high-speed rotates, and the air driven rotating tee in the centrifugal chamber is crossed discharged from air outlet after air ducting gets into door closure interlayer air channel again, thereby the inner negative pressure suction fresh air that forms in centrifugal chamber cools off motor, rotor.
Preferably, said door closure medial surface is provided with two air ductings, and said air outlet is located at door closure left surface or right flank, and said interlayer air channel is the labyrinth type air channel.
Further, said air ducting comprises base, body, and said body is a protruding arch and its inside is a cavity, and said body front openings is as air guide hole, and said base and door closure medial surface are fixed together.
The invention has the beneficial effects as follows that rely on the work characteristics of centrifuge rotor self to carry out the air draft cooling, simple in structure, manufacturing and operating cost can reduce greatly, and can keep a lower noise grade.The present invention need not compressor or the semiconductor refrigeration system and the cooling fan of complex and expensive, only depends on the structure of self just can obtain good cooling heat dissipation effect, can realize the low noise effect again.

Specific embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration:
Like Fig. 1, shown in Figure 2, a kind of table model high speed centrifuge comprises motor 1, rotor 2, centrifugal chamber 3, door closure 4; Said door closure 4 medial surfaces are provided with at least one air ducting 5, and said door closure 4 also is provided with air outlet 6, and said door closure 4 also is provided with interlayer air channel 7; One end in said interlayer air channel 7 is connected with air ducting 5; The other end is connected with said air outlet 6, and when centrifuge was worked, motor 1 drove rotor 2 rotation at a high speed; Discharge from air outlet 6 again after air driven rotating tee in the centrifugal chamber 3 are crossed the interlayer air channel 7 that air ducting 5 gets into door closures 4, thereby inner formation the in centrifugal chamber 3 sucks fresh air after the negative pressure motor 1, rotor 2 cooled off.With high speed rotor rotated 2 from as power; With the labyrinth type air channel 7 that gets in door closure 4 interlayers by the air ducting on the door closure 45 after the air nature driven rotary in the centrifugal chamber 3; In this air channel back haul, slow down, mix, thereby reduce the noise level at air outlet 6 places; Because air is got rid of from top, form negative pressure in 3 inside, centrifugal chamber simultaneously, the air inlet in the centrifuge bottom can suck fresh air, gets into centrifugal chamber around the fore-body pcb board of flowing through, centrifugal body, the motor and accomplishes cooling procedure.
Preferably, said door closure 4 medial surfaces are provided with two air ductings 5, and said air outlet 6 is located at door closure 4 left surfaces or right flank, and said interlayer air channel 7 is the labyrinth type air channels that formed by sound-absorbing material, can further reduce pneumatic noise.
Further, as shown in Figure 3, said air ducting 5 comprises base 5A, body 5B, and said body 5B is a protruding arch and its inside is a cavity, and said body 5B front openings is as air guide hole, and said base 5A and door closure medial surface are fixed together.The air ducting that this moulding is unique can effectively reduce the noise of air-flow in the centrifugal chamber.
The present invention drives the air in the centrifugal chamber through rotor, gets into the door closure air channel by air guide hole, in the air channel, slows down; Mix, get rid of, in body, form negative pressure simultaneously by air outlet; Suck fresh air by the fuselage bottom air inlet, when flowing through the pcb board of fore-body, it is lowered the temperature, tentatively slowed down simultaneously; Suck fresh air by the negative pressure that forms naturally, motor and rotor are cooled off.
The foregoing description provides to those of ordinary skills and realizes or use of the present invention; Those of ordinary skills can be under the situation that does not break away from inventive concept; The foregoing description is made various modifications or variation; Thereby protection scope of the present invention do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
