Embodiment 2:On the basis of embodiment 1, the circulation condensation structure 2 is honeycomb, and honeycomb is by several
The hole 4 of a rule distribution forms.Several holes 4 are that fork row is staggered or in-line arrangement is arranged.The advantage of honeycomb is efficient
Accumulation of heat and heat exchange.The d1mm that the central bore diameter of honeycomb is, outer aperture are d2mm, and the level interval of Kong Yukong is L
Mm, vertical interval are H mm, and the last layer hole heart is away from next layer of the adjacent holes heart away from being W mm.By the hole 4 to honeycomb into
Row fork row is staggered or in-line arrangement is arranged, and enhances the microturbulence of fluid field, improves the heat exchange efficiency of air and hold-over plate,
Fork row is staggered, within the scope of H=0.7L~1.2L, W=0.1L~0.6L, L=1.5d1~5d1, in-line arrangement arrangement, i.e. and W=
Then it is in-line arrangement structure, within the scope of H=0.7L~1.2L, L=20~50mm when 0.In d2=1.2d1~2d2, d1=5mm~
Within the scope of 50mm, the ratio of exit orifice and endoporus is rationally designed, increase the heat exchange area of air and hold-over plate and is further enhanced
Small scale turbulent condition improves air inlet wind speed, shortens hot-air time interval in honeycomb, and it is empty with heat to increase hold-over plate
The heat exchange amount of gas solves the problems, such as that the condensed water of hold-over plate and hot-air drips.
Embodiment 3:On the basis of embodiment 1, the circulation condensation structure 2 is trench structure, and trench structure is by several
The slot 6 of a rule distribution forms.Several slots 6 are that fork row is staggered or in-line arrangement is arranged.The same honeycomb of principle of trench structure
Structure, the rounded jet-like of outlet air of honeycomb, the outlet air of trench structure are in bar shaped jet-like, and the length U=2I of slot 6~
10I, I=5~30mm, rational trench structure are conducive to the VELOCITY DISTRIBUTION in fluid field, improve heat exchange efficiency.Slot 6 is not limited to
It is horizontally-arranged, can also be vertical setting of types, in the case where being disposed vertically, horizontally-arranged heat exchange efficiency is higher than vertical setting of types.Arrangement mode with time slot 6 is also classified into
In-line arrangement and fork row's two ways, the horizontal distance that through-hole is closed on upper layer with lower layer are W1, are that in-line arrangement formula is arranged evenly in W1=U,
In W=0.1U~0.5U, arranged evenly for fork row's formula, the arrangement mode for the row of pitching is more advantageous to the turbulent condition for causing fluid field.
Embodiment 4:On the basis of embodiment 2 or 3, the top and bottom of the handgrips 1 are designed with groove 5.Arc knot
The handgrips 1 of structure, advantage are that user is facilitated to fetch, and are easily installed and dismantle, in hot-air when flowing through hold-over plate handle,
Vortex dead zone is generated, causes to exchange heat unsmooth, is also easy to produce condensed water, if the space of groove 5 is larger, causes the short of fluid field at this
The air amount of flowing through on road, other regions is smaller, causes the whole thermal efficiency relatively low and condensation is dripped, as h3=3~10mm;h5
=0.5h4~0.8h4;Within the scope of h4=40~200mm, handgrips 1 not only increases only heat exchange area, also reduces simultaneously
Fluid boundary layer improves flowing velocity, reduces the vortex dead zone in handle region, solves the problems, such as that condensed water drips.Together
When ensure that in blow-molding process, the material quantity of handle position and the structural strength for increasing handle.The length U=30 of groove 5~
60mm, the diameter I of groove 5, within the scope of I=10-50mm, hold-over plate is inserted and grasped to groove 5 convenient for stretching for finger, while
Moving air and hold-over plate contact area are increased, improves velocity field and the temperature field of air flowing, improves air and hold-over plate
Heat exchange amount.
Embodiment 5:On the basis of embodiment 4, the water filling pore structure 3 includes water injection hole 7 and arcuate structure 8, arc
The shape of structure 8 is similar to trapezium structure, and greatly convenient for the welding of water injection hole, 7 height of water injection hole is the upper opening of arcuate structure 8
H2,3 height of water filling pore structure are h1, and special designing is that 7 height h2 of water injection hole is less than 3 structure height h1 of water injection hole knot, 1~3mm
In the range of, this implementation uses 2mm structure drops, the too small positioning for being unfavorable for technology controlling and process and equipment of drop, the too big work of drop
Skill difficulty is big and water injection hole structure height h1 is larger, is affected to fluid field, this implementation is solved because long-term pull is to water filling
The damage in hole 4, therefore the end cap seal of water injection hole 7 uses ultrasonic bonding, prior art weld to go out head cover and connect for a long time with end plate
It touches and squeezes, cause hold-over plate leakage, do not utilize the long-time service of hold-over plate.Hot-air is when flowing through hold-over plate bottom simultaneously, production
Raw vortex dead zone, causes to exchange heat unsmooth, is also easy to produce condensed water, if the space of water structure 3 is larger, cause fluid field at this
The air amount of flowing through of short circuit, other regions is smaller, causes the whole thermal efficiency relatively low and condensation is dripped, this implementation is reasonably set
Water filling pore structure 7 is counted, the opening width of structure upper is D mm, and structure bottom opening width is d mm, in d=0.5~0.85,
The range of D=10~100mm, the range of h2=5~25mm are conducive to reduce vortex dead zone and improve fluid field.This implementation is noted
The design parameter of outlet hole structure 3 is D=20mm, d=15mm, h2=10mm, and water filling pore structure 3 not only increases only heat-transfer surface
Product, while fluid boundary layer is also reduced, flowing velocity is improved, the vortex dead zone of hold-over plate bottom section is reduced, is improved
The energy utilization rate of hold-over plate solves the problems, such as that condensed water drips..
Embodiment 6:On the basis of embodiment 5, the solidification point of hold-over plate is at 10 DEG C~15 DEG C, the hold-over plate ontology
Internal cold-storage material is mainly made of inorganic salts and deionized water solution, and component ratio accounts for 90% or more, according to solution phase transformation
Principle, increasing sodium chloride composition ratio reduces the solidification point of water, by increasing sodium tetraborate, polyvinyl alcohol 3 and dodecyl
Sodium sulfonate equal solvent further increases the preceding heat of cold-storage material to enhance the viscosity and emulsifying effectiveness of solution.The cold-storage material at present
Amount of latent heat up to 275j/g.
The formula of the hold-over plate cold-storage material of this implementation is as follows:
Ingredient | Sodium chloride | Deionized water | Ammonium chloride | Sodium tetraborate | Dodecyl sodium sulfate | Polyvinyl alcohol |
Ratio | 14% | 78% | 3% | 1% | 1% | 3% |
This example is not limited solely to above-mentioned formula, and sodium chloride accounts for the 4%~18% of total ingredient, deionized water 72~88%
Total ingredient is accounted for, ammonium chloride 1~3%, dodecyl sodium sulfate 1%, sodium tetraborate 1~3%, polyvinyl alcohol 2~4% can
Obtain relatively high amount of latent heat.
