One end, the other end connects the other end of the moving guide rail.As shown in fig. 7, air channel inside has higher temperature and humidity, palpus
Water film thickness measurement motor 9 in water film thickness measurement apparatus is external in the environment.For moving guide rail along rotatable flat
The length direction of plate 6 is moved, while air channel also has certain complete seal, takes the first side plate 10 and the second side plate 12 to reserve
Water film thickness measures the spatial hole of motor 9 and moving guide rail activity, allows the moving guide rail can be in the length of rotatable flat board 6
Arbitrarily move on direction, remaining space protective cover 16 in the first side plate 10 and the second side plate 12, i.e. organ folding is filled up.With
Moving guide rail is driven to move along the length direction of rotatable flat board 6, the elasticity of the local location of protective cover 16 can change, but wind
The integrality in road is not destroyed.
The rotatable flat board outside cooling system air channel that the present invention is provided, also including massive plate substrate and flat board rotary shaft 8；
The rotatable flat board connects the massive plate substrate by the flat board rotary shaft 8.
The principle in the rotatable flat board outside cooling system air channel that the present invention is provided is as follows：From duct insert heater outlet 7 to
Horizontal range between flat board rotary shaft about 1.7m, if directly carrying out rigidity Hard link using stainless steel hard tube, it is impossible to adapt to
The needs of flat board change of pitch angle, so needing to introduce the connection of rectangle flanging canvas soft air duct.If all using being flexible coupling, from wind
The air that channel heater outlet 7 is gone out is easy to strut rectangle flanging canvas soft air duct, then the rotatable entry position of flat board 6
The wind speed at place becomes very unstable.Even if increasing after inlet hole plate carries out current stabilization process in the entry position of rotatable flat board 6, section
Wind speed uniformity and stability are still very poor.Reason is rectangle flanging canvas after air flows through rectangle flanging canvas soft air duct
The shape of soft air duct is being continually changing, and has very large disturbances so as to cause air-flow.Therefore, it is to reduce rectangle flanging canvas light air as far as possible
The deformation in road, takes the method that soft air duct and hard air channel combine, while soft air duct flanging, as shown in Figure 2.When air is passed through
Afterwards, rectangle flanging canvas soft air duct becomes rectangular duct, and comparatively its shape, changes less.In addition, in FIG, air is defeated
From the ground distance is higher to send hard tube 3 and the joint of air delivery hose 2, the extreme lower position of flat board can be highly can exceed that, when can turn
When the inclination angle of dynamic flat board 6 is more than 40 degree, air flow will appear from bending, accelerate disturbance, entry position section VELOCITY DISTRIBUTION
Become uneven.Now, as shown in figure 3, stainless steel air channel Hard link need to be redesigned, it is to avoid air flow bending occurs and shows
As.
Due to its lowest position of rotatable flat board 6, i.e. the porch of air delivery hose 2 is provided with moisture film and collects water tank
15, to compare with the discharge area of air delivery hose 2, the entrance sectional area of air delivery hose 2 has been reduced.In addition,
For opposing circular section, each point velocity distribution uniformity is poor on square-section, so arranging orifice plate current stabilization dress in entrance
Put, promote each point VELOCITY DISTRIBUTION on entrance section as far as possible uniform, as shown in Figure 4.
Cool exterior air conveying flow passage 1 is adopted and made with the following method：Along the length direction of rotatable flat board 6, in its surface structure
Build up the cuboid cavity that a cross section is rectangle.Specifically, by two blocks of stainless steel side plates, i.e. the first side plate 10 and the second side
Plate 12 is respectively welded at the both sides of rotatable flat board 6, along the width of rotatable flat board 6；Then along the length side of rotatable flat board 6
To some brace rods 13 are coupled together on the top of the first side plate 10 and the second side plate 12 with the mode of welding, all supports
Muscle 13 constitutes a supporting plane parallel to planar surface；Finally the space of supporting plane is filled up with some materials.Separately
Outward, there is heater at rotatable massive plate back, can bring up to its surface temperature more than 150 DEG C or so, or even 200 DEG C.Such as
Fruit will bear such hot environment, while be also convenient for observing the surface moisture film flowing of rotatable flat board 6, so must take transparent
The armorplate glass 5 of heatproof, is supported face sealing.The prepared screw-bolt hole on armorplate glass 5, takes bolted mode
It is fixed on brace rod 13.To prevent armorplate glass 5 from crushing, the position contacted with brace rod 13 in armorplate glass 5 is needed
Pad silica gel pad, as shown in Figure 5 and Figure 6.
The specific embodiment of the present invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can within the scope of the claims make various modifications or modification, this not shadow
Ring the flesh and blood of the present invention.
