The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, the compound evaporative condenser of remodeling of the plate pipe of the present invention, including blower fan 4, water pump 5,
Water-locator 6, collecting-tank 7；Also include plate pipe composite heat-exchanger 8；Plate pipe composite heat-exchanger 8 is positioned at water-locator
Between 6 and collecting-tank 7, water-locator 6 is connected by water pump 5 with collecting-tank 7；Blower fan 4 is positioned at that plate pipe is compound to be changed
One end of hot device 8.Described plate pipe composite heat-exchanger 8 by multiple plate pipe composite heat-exchange sheets by inlet header and
Outlet header connects composition.As shown in Figures 2 and 3, described plate pipe composite heat-exchange sheet includes being added by heat exchanger tube
(described processing can be that long heat exchanger tube is bent to coil pipe to the coil pipe 1 of work, it is also possible to is changing curved segment
The heat exchanger tube of heat pipe and straight section welds together becomes coil pipe), also include heat transferring plate 2.The present embodiment mid-game
Pipe 1 is formed by the bending of heat exchanger tube continuous S-shaped, and wherein the straightway of heat exchanger tube is the most substantially parallel, it is also possible to
Not parallel, this coil pipe 1 can also use other other shapes being applicable in evaporative condenser.Coil pipe 1
Heat exchanger tube can use copper pipe, stainless steel tube or coating steel pipe etc., and the cross sectional shape of its inner flow passage can be circle
The shapes such as shape, ellipse, spiral type, corrugated or olive shape.As those skilled in the art it is understood that
Coil pipe 1 surfaces externally and internally can use smooth surface, it is preferred to use is provided with the enhanced heat transfer surfaces of internal and external screw thread,
The most described coil pipe 1 outer surface also can be provided with hydrophilic or corrosion-inhibiting coating.This coil pipe 1 be provided with runner entrance and
Outlet, for being connected with inlet header, outlet header.In the present embodiment, the bending of described heat exchanger tube has multiple
Straight length；The straight length of adjacent described heat exchanger tube is parallel to each other, between the pipe of the straight length of adjacent described heat exchanger tube
Away from identical, or tube pitch is from being positioned at the upper strata first accepting spraying cooling water to being followed by by spraying cooling water
Layer tapers into；Can also be that the length of the straight length of described heat exchanger tube first accepts cool water shower from being positioned at
Upper strata is gradually increased to the lower floor being followed by by spraying cooling water.The material of heat transferring plate 2 can be carbon steel sheet, no

Cooling wind flows along the substantial distance direction of described coil pipe 1.
As shown in Figure 3 and Figure 4, described heat transferring plate 2 be provided with mounting groove 21, in the present embodiment, this peace
Put groove 21 to realize by the way of heat transferring plate 2 is carried out punching press, it is also possible to be to be at production heat transferring plate 2
Straight forming；The shape of this mounting groove 21 and the form fit of coil pipe 1.Coil pipe 1 is placed in mounting groove 21
In, the gap between coil pipe 1 and mounting groove 21 is filled with thermoconductive adhesive layer 3.In the present embodiment, described in lead
Thermal adhesive layer 3 is metallic filler layers zinc.Concrete way can be, by heat transferring plate 2, coil pipe 1 at high temperature
Liquid Zn in soak, make the zinc of liquid flow to coil pipe 1 with the gap of mounting groove 21, gap filled up,
The stickiness of liquid metal makes both cling, and when liquid metal cooled and solidified is solid-state, becomes thermoconductive adhesive layer 3,
It is filled between coil pipe 1 and mounting groove 21, both are fixed.In addition to zinc, it is also possible to select stannum, aluminum etc.
Metal or its metallic combination, they all have fusing point feature low, low-cost, cost performance height.
Further, in the present embodiment, the gap between described coil pipe 1 and mounting groove 21 is less than 10 millimeters,
When carrying out liquid metal and soaking, due to the stickiness of liquid metal, liquid metals can occur capillarity,
After infiltrating into the heat transferring plate 2 contact surface inside with coil pipe 1, can make formed in the gap of contact to lead
Thermal adhesive layer 3 is uniformly and thickness is thin, and not only making heat transferring plate 2 and coil pipe 1 fuse completely is an entirety,
And owing to the thickness of thermoconductive adhesive layer 3 is thin, effectively reduce contacting between heat transferring plate 2 with coil pipe 1
Thermal resistance.Gap between coil pipe 1 and mounting groove 21 is the least, and the capillarity of liquid metal infiltration is the most obvious,
The thermoconductive adhesive layer 3 formed can be the most uniform, and relatively cost and difficulty of processing are the biggest；10 millimeter
Gap width is that Optimum cost selects, and the gap width of 5 millimeter is best price/performance ratio selection, 3 millimeters
Within be even results optimal choice.Further, during for ensureing to soak high temperature fluent metal, coil pipe 1
And spacing between heat transferring plate 2 can be sufficiently small, can heat transferring plate 2 stamp out some stopper slots and/or
Tack weld (not shown), before soaking, is welded by stopper slot limit mounting or tack weld part,
First realize pre-fixing to coil pipe 1.The mode that can also use fixture makes both first pre-fix, but operation is more multiple
Miscellaneous.
The heat of coil pipe 1 is conducted to heat transferring plate 2 by thermoconductive adhesive layer 3, and heat transferring plate 2 becomes coil pipe 1
Fin, be greatly increased heat exchange area, directly strengthen coil pipe 1 heat transfer effect；Heat transferring plate 2 is again simultaneously
There is the effect of guide cooling water, make cooling water form solid stream of water on the surface of heat transferring plate 2, it is to avoid cold
But the unordered water that flies of water, improves cooling water use efficiency.Additionally, due to heat transferring plate 2 is an entirety, can keep away
Exempt to couple the staggered flowing of cooling water at place with coil pipe 1, it is ensured that water distribution rate.
On the other hand, described thermoconductive adhesive layer 3 can use heat conduction viscose glue to replace；Only need to be equal for heat conduction viscose glue
At the even mounting groove 21 spreading upon heat transferring plate 2, more directly coil pipe 1 is received in mounting groove 21
Bonding (for partly needing the heat conduction viscose glue being applied in combination, the most also need to smear the heat conduction of cooperation on coil pipe 1
Viscose glue), simple installation, technique are simple.But existing heat conduction viscose glue, such as organosilicon heat-conducting glue, asphalt mixtures modified by epoxy resin
Fat AB glue, polyurethane guide hot glue etc., it is strong that its capacity of heat transmission is all not so good as the metal such as zinc, aluminum, and in cloth glue mistake
Journey easily occurs non-uniform phenomenon, it is possible that air layer when causing coil pipe 1 to be adhered in mounting groove 21
Heat insulation phenomenon, affects heat exchange efficiency.
Perforate, ripple, bending, guiding gutter, dovetail groove, reinforcement can also be set on heat transferring plate 2
Etc. structure, to realize increasing water distribution effect, preventing from flying water and strengthening the effects such as robustness.Further,
The through hole (not shown) of some elongate holes, circular hole or other shapes can be offered at mounting groove 21, when
The when that coil pipe 1 being placed in mounting groove 21, can be exposed to outside mounting groove 21 with some, can be direct
Contacting with condensed water, this kind of way can increase the direct contact surface of coil pipe and water and amass, simultaneously tapping due to
Water flowing is had the effect of disturbance can strengthen copper tube heat exchange by out-of-flatness, but weakens heat transfer plate to a certain extent
The rib effect of sheet.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to limit present invention protection with this
Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the present invention and replacement
Belong to scope of the present invention.
