Abstract
The invention discloses a dynamic airflow adjusting air valve which comprises a periphery framework, fan blades and gear wheels. The gear wheels are meshed with one another in a staggered mode and then connected with the periphery framework, two of the gear wheels are located at two ends of each of the fan blades and used for clamping the fan blades, the rotation degrees of the fan blades are adjusted by means of the rotation of the gear wheels, and the offset value between each two fan blades is 0.55mm. According to the dynamic airflow adjusting air valve, the possibility of the deformation of the fan blades is considered, the normal operation is guaranteed, the temperature difference in a cabinet is real-timely detected by a temperature sensor, load change values are obtained according to the temperature difference, by means of the deformation of the fan blades, the dynamic airflow adjusting air valve is capable of evenly feeding air, and the function of cooling the cabinets according to the requirement is achieved.
Description
Technical field
[0001] the present invention relates to a kind of controlling device, particularly relate to a kind of dynamic air current and regulate air-valve.
Background technique
Manually (electronic) volume damper generally is installed in air-conditioning, the air system plumbing, and is not enough below manually (electronic) volume damper exists: one, not enough on the function: need the human intervention manual tune, degree of regulation is not high; Can't apply to records center; Can't carry out intelligence according to records center's required refrigerating capacity of single rack and regulate, can't reach energy-saving effect, not have man-machine interaction interface, not have safety protection strategy etc. with records center's precision air conditioner interlock.Two, not enough on the structure: the inconvenient dismounting of frame structure is not easy to safeguard; Fan blade and gear means of fixation are simpler, do not consider that fan blade deformation maybe; The fan blade design causes air distribution chaotic not according to aerodynamics; Appearance design is coarse, does not meet the aesthetic requirement of current society.
Summary of the invention
Technical problem to be solved by this invention provides a kind of dynamic air current and regulates air-valve; It has considered fan blade deformation possibility, guarantees that operation is normal, according to the temperature difference in the temperature transducer actual measurement rack; Obtain load variations numerical value; And, guarantee the balanced ventilation of dynamic air current adjusting air-valve ability through fan blade deformation, reach the function of cooling as required to rack.
The present invention solves above-mentioned technical problem through following technical proposals: a kind of dynamic air current is regulated air-valve; It is characterized in that; It comprises peripheral frame, wind page or leaf, gear; Staggered engagement back is connected with peripheral frame between the gear, and two gears are positioned at the two ends of wind page or leaf and with the clamping of wind page or leaf, regulate wind page or leaf angle of swing through the rotation of gear.
Preferably, the side-play amount between said two wind pages or leaves is 0.55mm.
Positive progressive effect of the present invention is: the present invention has considered that fan blade deformation maybe; Guarantee that operation is normal; Based on the temperature difference in the temperature sensor actual measurement rack; Obtain load variations numerical value; And through fan blade deformation; Guarantee the balanced ventilation of dynamic air current adjusting air-valve ability, reach the function of cooling as required rack.

Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technological scheme of the present invention.
To shown in Figure 3, dynamic air current of the present invention is regulated air-valve and is comprised peripheral frame 1, wind page or leaf 2, gear 3 like Fig. 1, and staggered engagement back is connected with peripheral frame 1 between the gear 3, and two gears 3 are positioned at the two ends of wind page or leaf 2 and with 2 clampings of wind page or leaf.As shown in Figure 4, the side-play amount D between two wind pages or leaves is 0.55mm, considered fan blade deformation maybe, guarantee that operation is normal.The wind page or leaf is under closed state, and two adjacent wind pages or leaves produce less gap, guarantee seal like this.
The present invention is mainly used in the building of data center machine room or similar functions; The working principle that dynamic air current of the present invention is regulated air-valve is following: gear rotates; Drive all wind pages or leaves and rotate together, regulate the size of wind page or leaf angle of swing, thus the air quantity of control air channel exhaust outlet.The present invention has considered fan blade deformation possibility, guarantees to move normally, surveys the temperature difference in the rack based on temperature sensor, acquisition load variations numerical value, and through fan blade deformation, the balanced ventilation of assurance dynamic air current adjusting air-valve ability reaches the function of cooling off as required to rack.The present invention measures the turnover wind-warm syndrome degree on rack surface, and the adjustment air output is to guarantee the threshold limit value of the eternal less than user set of entering air temp that rack is surperficial.The present invention has considered fan blade deformation possibility, guarantees that operation is normal, according to the temperature difference in the temperature transducer actual measurement rack, and acquisition load variations numerical value, and logical
Cross fan blade deformation, guarantee the balanced ventilation of dynamic air current adjusting air-valve ability, reach the function of cooling as required rack.The present invention can distribute and send appropriate air quantity with the ability of instant adjustment air-supply automatically and come cooling equipment to make the blower fan of precise machine room air conditioner to move with optimum efficiency more exactly.Dynamic air current of the present invention regulate that air-valve can be handled diversified burden requirement simultaneously and can the low-density rack of supercooling with energy saving.Because the variable air rate blower fan is arranged by single rack rather than row; Therefore it can reduce the air-supply of low-density rack and increase and comes the balance total blast volume to highdensity rack air output with the different energy consumption density based on rack, and does not increase floor static pressure and expensive precision air conditioner quantity to practice thrift cost.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
