Background technology
Evaporative condenser generally use coiled set of heat exchange tubes is into heat exchanger on current market.In heat exchanger outer surface
It is cooled down with shower water, and air evaporation is made to take away heat using the shower water of cycle.Due to nothing between the upper down tube of coil pipe
Medium guide cooling water flows, and when cooling water lands from top to bottom, under the traction of vertical wind direction, cooling water is unordered to wave easily
It generates and flies water, water distribution is uneven on coil pipe, easily deposits and does, and reduces exchange capability of heat and there are fouling risks, also having causes to exchange heat
Less efficient, heat exchanger consumptive material is more and the shortcomings such as manufacture cost height;On the other hand, cooling water flow through multilayer coil pipe surface and
Gap, in absorption coil after the heat of gas, temperature rise is larger, even if heat exchange, which occurs, with the cooling air flowed through one
Fixed cooling, but cooling extent is smaller, and the temperature for causing coil pipe region is higher, and is substantially reduced the cooling efficiency of coil pipe.

Specific embodiment
The utility model is further illustrated with embodiment, as described below is only the preferred embodiment of the utility model below
, it is not intended to limit the utility model, it is right although the utility model is described in detail with reference to the foregoing embodiments
For those skilled in the art, can still modify to the technical solution recorded in foregoing embodiments or
Equivalent replacement is carried out to which part technical characteristic.Any modification within the spirit and principle of the utility model, being made,
Equivalent replacement, improvement etc., should be included within the scope of protection of this utility model.
It please refers to Fig.1 with shown in Fig. 2, the utility model includes multiple sub- heat exchangers for the heat exchanger of evaporative condenser
100 and the filler 200 between sub- heat exchanger 100;The filler 200 is filled between sub- heat exchanger 100;The sub- heat exchange
It is in parallel between device 100.Shown in please referring to Fig.3, the filler 200 includes zigzag deflector 210 and water receiving mechanism 220;Please
Refering to what is shown in Fig. 4, the flanging bore 211 being provided with for flowing backwards liquid of the corner of the zigzag deflector 210;Please refer to Fig. 5
