It is preferred that coefficient a span is 6-10.
The utility model also provides a kind of evaporative condenser, and its feature is, it includes a blower fan and an above-mentioned expansion
Pressure pipe, the diffuser pipe is installed at the air outlet of the blower fan.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, produce the utility model it is each compared with
Good example.
Positive effect of the present utility model is:
The evaporative condenser of the present utility model for being provided with diffuser pipe, the evaporative condenser with being fitted without diffuser pipe
Compare, air quantity can be greatly improved;Compared with changing mode of the rotating speed to improve air quantity, power consumption can be greatly lowered.This practicality
New diffuser pipe production and install simple, and install diffuser pipe evaporative condenser energy-saving effect significantly, can push away
Wide application.
Brief description of the drawings
Fig. 1 is the structural representation of the diffuser pipe of the utility model preferred embodiment.
Fig. 2 is the structural representation of the evaporative condenser for being provided with diffuser pipe of the utility model preferred embodiment.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made all belongs to
The scope protected in the utility model.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of evaporative condenser, and it includes a diffuser pipe 1 (see Fig. 1) and one
Blower fan 2, the diffuser pipe 1 is installed on the air outlet of the blower fan 2.
The diffuser pipe 1 is cone, and the inlet diameter of the diffuser pipe 1 is D1, and the outlet diameter of the diffuser pipe 1 is D2, should
The height of diffuser pipe 1 is H, and outlet diameter D2 is more than inlet diameter D1.
Wherein, H and D1 and D2 relation is:H=a* (D2-D1)/2, a is coefficient, and coefficient a span is 6-10,
Inlet diameter D1 numerical value is identical with the air outlet of the blower fan 2.
Inlet diameter D1 value is 1200mm, and outlet diameter D2 value is 1500mm, and height H value is
1160mm。
The effect after diffuser pipe installation in order to verify evaporative condenser, the steaming to being fitted without and being mounted with diffuser pipe
Hairdo condenser is tested contrast.
1st, the instrument and test method that test is used
(1) air-quantity measuring:Use ZRQF types heat bulb (ZRQF be using measure wind speed as basic function and by wind-warm syndrome,
Relative humidity measurement function is combined and one instrument), it is each on 9 fixing points in the vertical horizontal air intake surface of air intake surface and tower top
Tested.
(2) air stagnation pressure value is surveyed in the air chamber of blower fan suction inlet bottom, measuring instrumentss are to use the stagnation pressure with kuppe
Probe (handing over big manufacture) and the YAMA MOTO W0-80 pressure difference meters of Japan's production.
2nd, test result
The total blast volume for being fitted without diffuser pipe is G'=56284m3/h;It is G=to install the total blast volume after diffuser pipe
69844m3/h。
The ratio that air quantity is improved is (G-G')/G=(69844-56284)/69844=24.1%.
3rd, validation test
