Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
Embodiment mono-
The embodiment of the present invention provides a kind of heat-exchanger rig, can be used in the rack of communication apparatus, information technoloy equipment, each equipment is dispelled the heat, and as shown in Figure 4,5, this heat abstractor comprises: the first circulation air path 1, the first fan 2, the second circulation air path 3, the second fan 4 and heat exchange core 5;
Wherein, the first fan 2 is arranged at described the first circulation air path 1, the first fan 2 and can makes the wind flow in the first circulation air path 1 circulate; The second fan 4 is arranged at described the second circulation air path 3, the second fans 4 can make the wind flow in the second circulation air path 3 circulate;
The first cycle heat exchange air channel 513 of heat exchange core 5 is communicated with the first circulation air path 1, and the second cycle heat exchange air channel 521 is communicated with the second circulation air path 3.Like this can be under the first fan 2 effects, the first cycle heat exchange air channel 513 of the heat exchanging body forming through multiple flat tubes 51 of heat exchange core 5, make interior formation the first heat exchange circulation of the first circulation air path 1, under the second fan 4 effects, the second cycle heat exchange air channel 521 of the heat exchanging body forming through multiple fins 52 of heat exchange core 5, makes interior formation the second heat exchange circulation of the second circulation air path 3.Because heat exchange core 5 is made up of with the multiple fins 52 that are arranged on flat tube 51 outsides the multiple flat tubes 51 that are adjacent to arrangement, effectively increase the area of heat-transfer surface, thereby made this heat-exchanger rig there is good radiating effect.
In reality, the first circulation air path 1 of this heat-exchanger rig can be used as the interior circulation of rack, and the first circulation air path 2 is as outer circulation, also can the first circulation air path 1 as the outer circulation of rack, and the first circulation air path 2 is as interior circulation.
In above-mentioned heat-exchanger rig, the length in the second cycle heat exchange air channel of heat exchange core is less than the length in the first cycle heat exchange air channel.The path in such the second cycle heat exchange air channel is short, and resistance is little, can not affect the circulation of whole the second circulation air path air quantity, also can not affect radiating effect because of deficiency in draught.
In above-mentioned heat-exchanger rig, each fin of heat exchange core is arranged on each flat tube perpendicular to the body of flat tube.
In above-mentioned heat-exchanger rig, the first circulation air path and the second circulation air path are not connected, the second cycle heat exchange air channel and the first mutual square crossing in cycle heat exchange air channel and not connected that heat exchange core forms; Can make like this first cycle heat exchange air channel, the second cycle heat exchange air channel all can be used as interior circulation or outer circulation, and can not influence each other.
In above-mentioned heat-exchanger rig, enhanced heat exchange structure all can be set on the flat tube inwall of heat exchange core and on fin, further to increase the heat-exchange surface of flat tube, enhanced heat exchange structure can be: any one or several in many rib structures, helical structure, salient point, also can adopt other structure that can increase area of dissipation, not go to live in the household of one's in-laws on getting married and tell one by one at this.
In above-mentioned heat-exchanger rig, the heat-exchange working medium in the first circulation air path and the second circulation air path is gas.In such the first circulation air path and the second circulation air path, all can realize absolutely empty heat exchange, needn't adopt other heat radiation working medium, have advantages of that cost is low and be easy to safeguard.
In above-mentioned heat-exchanger rig, can be at the outer setting of the second fan 4 outer cover 6 that keeps out the wind, keep out the wind the air outlet of outer cover 6 corresponding to the air inlet in the second cycle heat exchange air channel 521 of heat exchange core 5, cover the second fan 4 by the outer cover 6 that keeps out the wind like this, guide the wind-force of the second fan 4 into second cycle heat exchange air channel 521, do not increasing under the prerequisite in the second circulation air path 3 spaces like this, with better simply structure, lower cost, ensure the normal circulation operation of wind-force in the second circulation air path 3, can not impact with the second circulation air path 1.
Above-mentioned heat-exchanger rig is absolutely empty heat exchange, can be divided into interior circulation (the circulation cooling passage that multiple flat tubes of the first circulation air path, heat exchange core and the first fan form, be the peripheral passage of arrow A instruction in Fig. 4) and two parts of outer circulation (the circulation cooling passage that multiple fins of the second circulation air path, heat exchange core and the second fan form, the i.e. peripheral passage of arrow B instruction in Fig. 5).Internal circulation heat-exchanging face is multiple flat tubes of spread configuration, and the air stream of interior circulation is through flat tube, carries out heat exchange with heat-transfer surface in flat tube and the tube wall of flat tube.
The heat-transfer surface of external circulation heat exchanging face is multiple fins, and the flat tube of multiple fins and interior circulation is set together, the vertically air channel of interior circulation of heat-transfer surface direction.
The operation principle of inner-outer circulation: the power of interior circulating current is provided by the first fan, in the airflow passes that the first fan provides, the flat tube of circulation, carries out heat exchange with the fin of outer circulation.The power of outer circulation air-flow is provided by the second fan, and air-flow enters external circulation air inlet from the second fan, reaches the air channel of outer circulation, enters the main heat-transfer surface of outer circulation from air channel, and airflow passes heat exchange fin, carries out heat exchange, discharges from outer circulation air outlet.
On the flat tube of interior circulation and the fin of outer circulation, enhancing heat exchange structure can be further set, such as being divided into multiple separate spaces, design salient point, increases groove, and fin is windowed etc.On the cavity of outer circulation, also can increase the structures such as fin, salient point or groove, strengthen heat exchange.
The air intake vent air quantity of outer circulation, through the second fan, enter heat exchange core in cavity, reach the fin district of outer circulation, the fin district that flows through, carries out sufficient heat exchange, then is discharged by air outlet.
The material of above-mentioned making heat exchange core flat tube and fin can gold mining belongs to, the nonmetal or alloy of perfect heat-dissipating etc.
First, second circulation air path material therefor of above-mentioned making can adopt metal, such as aluminium, copper, metal alloy etc.; Also can adopt plastic material.
In use, for multiple flat tubes of the heat exchange core of interior circulation, also can be for outer circulation, and for the fin of the heat exchange core of outer circulation, also can be for interior circulation.Be that heat exchange core can exchange use for the heat exchange structure of inside and outside circulation.
The heat abstractor that the embodiment of the present invention provides, because the heat-transfer surface of its heat exchange core is large, can further promote the exchange capability of heat to rack, meets the growing radiating requirements of product power consumption, and its structural design is simple, and cost is low.
