Abstract
The utility model discloses a wind coil filter with variable resistance coefficients, and relates to wind coil filters. The wind coil filter with the variable resistance coefficients comprises a shell body (1) and a plurality of fan blades (2) arranged in the shell body. The fan blades (2) are connected with the shell body (1) in a pivoted mode, one fan blade (2) is connected with an adjusting knob (3) which is installed on the shell body (1), the fan blades (2) are respectively fixedly provided with a connecting arm (4) and provided with a connecting rod (5), and the connecting arms (4) are connected with the connecting rods (5) in a pivoted mode. According to the wind coil filter with the variable resistance coefficients, the resistance coefficient between Pn and Pn.1 is adjusted by adjusting the air exhaust angle of a filter fan, therefore the pressure at the position of Pn.1 is larger than the pressure at the position of Pn+1.1 no matter how much the pressure at the position of Pn is, the purpose that the hot air flow in an equipment cabinet is exhausted on the condition that the power of a draught fan is not high is achieved, and heat dissipation in an MCC room is achieved.
Description
Technical field
The utility model relates to wind coil pipe filter.
Background technology
It is that the mode of air circulation realizes the cooling of computer room temperature that current power station MCC air conditioner in machine room technology adopts, and by the thermal current that the wind coil pipe will be produced to thermal source, is discharged to outdoorly, simultaneously that outdoor cold air suction is indoor, has reached the assurance indoor temperature.In whole circulation, high-power blower is indispensable, can be described as even the soul of air conditioner in machine room.Simultaneously, because the hot blast of air-conditioning cold wind and equipment discharge is all delivered in the machine room space, both are very easy to mutually mix and cause Efficiency Decreasing.And in for thermal source gas purging process, blower fan must guarantee that the gas pressure of all positions in air channel all will be lower than bleed pressure (P1.1<P2.1<P3.1<P4.1<P5.1), under the condition of natural exhaust: the air draft between P1 and P1.1 is to discharge air-flow by common exhaust outlet, pressure drag is very little, can suppose P1=P1.1, P2=P2.1, if P2<P1, in order to guarantee normal air draft, just must lower the pressure that P2.1 goes out, the discharge of guarantee hot gas, now only way is exactly by blower fan, the air-flow at P2.1 place to be discharged by pressure, can increase the power of the power of blower fan like this.
Summary of the invention
The purpose of this utility model is to provide a kind of wind coil pipe filter of regulating the adjustable resistance coefficient of windage resistance coefficient.
The utility model is that the adopted technical scheme that achieves the above object is: a kind of wind coil pipe filter of adjustable resistance coefficient, comprise housing, be arranged on the flabellum in housing, flabellum and housing pivot joint, wherein a flabellum connects an adjustment knob, adjusting knob is arranged on housing, all flabellums are fixed respectively a link arm, and a connecting rod is set, link arm and connecting rod pivot joint.
Preferably, a rubber tire is set between described link arm and connecting rod.
Preferably, the described vertical support bar that arranges in housing, an end of flabellum is articulated on vertical support bar, and the termination of this end is through vertical fixedly link arm, link arm and connecting rod pivot joint of support bar.
The utility model is regulated the resistance coefficient between Pn and Pn.1 by the air draft angle of regulating the filter fan, thereby realize no matter the pressure at Pn place is much, can guarantee that the pressure at Pn.1 place is greater than the pressure at Pn+1.1 place forever, thereby realize in the situation that the little purpose that thermal current in rack is discharged of power of fan, guarantee to realize the purpose of all heat radiations in the MCC room in the situation that power of fan is less.
The accompanying drawing explanation
Fig. 1 is the floor map of the utility model preferred embodiment;
Fig. 2 is the schematic diagram of another angle of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of wind coil pipe filter of adjustable resistance coefficient, comprise housing 1, be arranged on the flabellum 2 in housing, flabellum 2 and housing 1 pivot joint, wherein a flabellum 2 connects an adjustment knob 3, adjusts knob 3 and is arranged on housing 1, and all flabellums 2 are fixed respectively a link arm 4, one connecting rod 5 is set, link arm 4 and connecting rod 5 pivot joints.
One rubber tire 6 is set between described link arm 4 and connecting rod 5.The pivot joint that is arranged so that between link arm 4 and connecting rod 5 of rubber tire 6 is rotated more smooth and easy.
The described vertical support bar 7 that arranges in housing, an end of flabellum 2 is articulated on vertical support bar 7, and the termination of this end is through indulging fixedly link arm 4 of support bar 7, link arm 4 and connecting rod 5 pivot joints.Separately establish vertical support bar 7 and support flabellum 2, the interlock part is placed to vertical support bar 7 belows, make the utility model more compact on the whole.
Adjust the air draft angle of knob 3 filter electric fans 2 by adjusting and regulate the resistance coefficient between Pn and Pn.1, thereby realize no matter the pressure at Pn place is much, can guarantee that the pressure at Pn.1 place is greater than the pressure at Pn+1.1 place forever, thereby realize in the situation that the little purpose that thermal current in rack is discharged of power of fan, guarantee to realize the purpose of all heat radiations in the MCC room in the situation that power of fan is less.
