The invention discloses a novel device for evenly adjusting the air intake of a finned heat exchanger, which comprises a fan and a finned heat exchanger. Adjusting devices are distributed symmetrically on both sides of the heat exchanger. The adjusting device includes baffles and springs. The baffles are installed on the side of the finned heat exchanger at equal intervals from top to bottom through springs. The present invention adds baffles and springs to the air inlet side of the original finned heat exchanger. When the incoming air passes through the finned heat exchanger, the wind pressure presses the baffles to make the air inlet channel smaller; At the same time, the active force of the spring is balanced with the effect of the wind pressure. When the wind enters, the upper baffle can have a large closing angle (small opening angle), and vice versa. The air inlet passes through the fin heat exchanger more evenly, which increases the overall heat transfer capacity of the fin heat exchange, and optimizes the distribution of the wind speed and flow field of the fin heat exchanger of the cooling top air outlet system, so that the wind speed distribution tends to be uniform.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, a kind of novel finned heat exchanger enters the wind even regulation device, including blower 1 and finned changes
Hot device 2, the top of finned heat exchanger 2 are equipped with the upward blower 1 of air outlet, and the two sides of finned heat exchanger 2 are symmetrically divided
It is furnished with regulating device 3, regulating device 3 includes baffle plate 31 and spring 32, and baffle plate 31 is equidistant from top to bottom by spring 32
It is mounted on the side of finned heat exchanger 2, baffle plate 31 can swing up and down by spring 32.Baffle plate 31 with it is finned
The angle of heat exchanger 2 is air inlet angle, and angular range is 10 ° -41 °, and angle is sequentially increased baffle plate 31 from top to bottom, guarantees two
The air inlet on side tends to be balanced, and the stress of baffle plate 31 mainly has 2, and one is the active force from wind pressure, another comes
From the torsion of spring 32, when two power are balance, 31 aperture of baffle plate is fixed, and constant motionless, baffle plate 31 is by wind pressure
Calculation of the force is as follows: set angle as θ, length and width a, b, wind speed V,
wp=0.5rv2/ g=wp=v2/1600
FW=wp* cos θ * a*b=cos θ * a*b*v2/1600
Wherein wpFor wind pressure, FWFor wind action power, baffle plate 31 is that calculating is as follows by the torsion of spring 32:
FN=0.5*b* Δ θ
Wherein FNFor torsion, Δ θ is the variation of the angle of spread, stress balance:
FN=0.5*b* Δ θ=FW=cos θ * a*b*v2/ 1600, by above-mentioned simplified formula are as follows:
Δθ∝cosθv2, to obtain the variation very wind-force of angle into similar inverse relation, entering the wind can tend to flat in this way
Weighing apparatus, the therefore it will be seen from figure 1 that intake velocity of finned heat exchanger 2 is roughly the same, as can be seen from Figures 2 and 3 baffle plate
31 expanded angle is different, and the high aperture of wind speed above is small, and wind speed is small, and aperture is big.
From 4 and 5 as can be seen that the size flow velocity that existing top air-out type refrigeration equipment is entered the wind has apparent difference, wind speed
Size from top to bottom, be high to Low.In specific actual use, the gap of the finned heat exchanger air inlet of 1 meter of height has 2.5
More than, the wind speed of most upper one layer (width 100mm) has 2.8 meter per seconds, and the wind speed of basecoat (width 100mm) is about exactly 0.3
Between~0.5 meter.
Working principle: the distance according to finned heat exchanger 2 apart from blower 1, air quantity are had nothing in common with each other, and close air quantity is big, far
Air quantity it is small, increase the partial pressure active force that baffle plate 31 allows wind speed to generate and turn down the gap of air inlet；On baffle plate 31 also simultaneously
The torsion that one spring 32 is formed, the power generated with wind pressure is on the contrary, the two interaction reaches balance.So, apart from wind
Machine 1 into wind speed it is more big, the Action of Wind pressure of generation is big, make baffle plate 31 close angle it is big, the gap of air inlet becomes smaller；Instead
It, distance is remote, and closing angle is small, and the gap of air inlet is big, so that air volume adjustment be made to tend to uniform.
In summary: novel finned heat exchanger provided by the invention enters the wind even regulation device, original finned
The inlet side of heat exchanger 2 increases baffle plate 31 and spring 32, and when air inlet is by finned heat exchanger 2, wind pressure pushes down baffle plate
31, so that the channel of air inlet is become smaller；The active force of spring 32 is balanced with the effect of wind pressure simultaneously, keeps baffle plate 31 to close certain
Angle, there is a multiple groups baffle plate 31 from top to bottom in finned heat exchanger 2, and air inlet when can make the baffle plate 31 of top close angle
It spends big (opening angle is small), following is on the contrary.Air inlet is more average by finned heat exchanger 2, increases the entirety of fin heat exchange
Exchange capability of heat, the wind speed control distribution problem of the finned heat exchanger 2 of optimization refrigeration ejection wind system, is intended to wind speed profile
Uniformly.
