Air channel air-out chamber 3 is divided into the first cavity for corresponding to the first blower fan 2 and the second blower fan 4 respectively by the setting of dividing plate 6
31 and second cavity 32, so as to directly impact agitation when eliminating the first blower fan 2 and the second 4 air-out of blower fan, effectively prevent two
Crossfire between blower fan, reduces power loss, has air quantity and is obviously improved, and air-out efficiency is improved.For the noise of unit
A certain degree of improvement can be obtained simultaneously.Solve this area and crave for always and solve but unsolved noise asking greatly all the time
Topic.
In the technical program, dividing plate 6 at least should be isolated the air side of air channel air-out chamber 3.Air side is relative
Region in concept, i.e. air outlet certain distance.In order to preferably reduce impact, dividing plate 6 may extend to whole air channel air-out chamber
3。
By taking type of being blown on 90KW as an example, in the case of operating mode and internal configuration identical, contrast is not provided with dividing plate and set
Put two kinds of situations progress experiments of dividing plate and can obtain data below:
| Experimental project | It is not provided with dividing plate | It is provided with dividing plate |
| Refrigerating capacity | 88KW | 92KW |
| Noise | 64dB | 63dB |
In addition, dividing plate 6 can be from the disassembled and assembled freely of air channel air-out chamber 3, so that eliminating needs some parts of air channel air-out chamber 3
Dividing plate 6 could be taken out after dismounting, improve convenience, it is convenient that the failures such as the blower fan inside air channel air-out chamber 3, circuit are carried out
Safeguard.
Fig. 3 is refer to, the inner side of 3 inner side connection framework of air channel air-out chamber 5 has certain length L, L≤200mm, so set
Meter reduces the size that the edge of air channel air-out chamber 3 is protruded, and in the case where not increasing part, reduces the edge of air channel air-out chamber 3
There is certain gas backstreaming phenomenon in position.
If in addition, conditions permit, can be realized and reduce, even in parts such as the position of air channel air-out chamber 3 increase baffle liners
Eliminate backflow phenomenon.
The present embodiment in the form of air channel air-out chamber bottom air intake, top air-out to illustrate the utility model, but this reality
It is applied to all air intakes and air-out direction identical two fans air channel cavity body structure with new.
In the present embodiment, the first blower fan 2 and the second blower fan 4 are centrifugal blower.It should be evident that the technical program can also be answered
For other blower fan types, such as axial flow blower.
The present embodiment describes the principle of the technical scheme, the first cavity 31 and the second cavity 32 with the situation of two blower fans, i.e.,
Two sub-air channels.It should be evident that the technical scheme applies also for the situation of multi fan, and when blower fan is multiple, adjacent two wind
Dividing plate is provided between machine, air channel cavity is divided into the sub-air channel of correspondence blower fan by dividing plate.
The utility model is simultaneously there is provided a kind of air-conditioning system using the fan air channel structure.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
