In one embodiment, the casing 4 comprises an air supply section 3 between the top of the heat exchanger 7 and the upper air inlet 10, and an air supply fan 6 is arranged in the air supply section 3.
In another embodiment, the counter-rotating axial fans include a first axial fan disposed between the heat exchanger 7 and the upper tuyere 10 and a second axial fan disposed between the lower tuyere 11 and the auxiliary tuyere 12. In this embodiment, since the lower air inlet 11 is located between the two axial fans, the lower air inlet 11 is an air inlet regardless of the upper air outlet or the lower air outlet.
An upper wind sweeping blade 13 is arranged at the upper wind port 10, a lower wind sweeping blade 14 is arranged at the lower wind port 11, and an auxiliary wind sweeping blade 15 is arranged at the auxiliary wind port 12. The size of the air inlet at the upper air inlet 10 can be adjusted by adjusting the wind sweeping angle of the upper wind sweeping blade 13, the size of the air inlet at the lower air inlet 11 can be adjusted by adjusting the wind sweeping angle of the lower wind sweeping blade 14, and the size of the air inlet at the auxiliary air inlet 12 can be adjusted by adjusting the wind sweeping angle of the auxiliary wind sweeping blade 15.
When the wind sweeping blades are perpendicular to the wind outlet, namely when the wind sweeping angle is 90 degrees, the wind sweeping angle is the largest, the area of the wind port is the largest, when the wind sweeping angle of the wind sweeping blades is 0 degrees, the wind sweeping angle is the smallest, and at the moment, the wind port is closed.
A flow guide ring is arranged between the air supply section 3 and the heat exchanger 7.
The water conservancy diversion circle includes circle body 1 and the water conservancy diversion spare 2 of setting on the internal perisporium of circle body 1, and water conservancy diversion spare 2 projects in the internal perisporium of circle body 1 towards the center of circle body 1, and water conservancy diversion spare 2 extends along the axial direction of circle body 1 to carry out the water conservancy diversion to the fluid that flows through the water conservancy diversion circle.
For convenience of description, the following description will be made of the embodiments by taking a fluid as an example.
This water conservancy diversion circle is provided with along axially extended water conservancy diversion spare 2 on the internal perisporium of circle body 1, can carry out water conservancy diversion and regular through the air current of water conservancy diversion circle to 2 pairs of flowings through the water conservancy diversion of spare to effectively improve the air current flow state in the wind-guiding passageway, reduce the random disturbance of air current, reduce the production of vortex, reduce aerodynamic noise, increase air volume.
The water conservancy diversion piece 2 is the sand grip structure for example, and the length extending direction of sand grip is the axial direction of circle body 1 to can carry out effective water conservancy diversion and regular to the air current that flows along the axial through circle body 1 etc. make the stability that the air current flows increase, reduce the probability of appearing of mixed and disorderly vortex, improve the flow efficiency of air current. The structure of sand grip can be many, evenly arranges at interval on the circumference of circle body 1 to guarantee the flow homogeneity of air current better, play more excellent air current water conservancy diversion effect.
In this embodiment, the flow guide member 2 is a plurality of flow guide ribs arranged along the circumference of the ring body 1 at intervals. Preferably, the guide ribs are uniformly arranged along the circumferential direction of the ring body 1 at intervals. Set up water conservancy diversion spare 2 into the rib structure, can standardize the thickness and the shape of water conservancy diversion spare 2 for water conservancy diversion spare 2 reduces the flow resistance of air current, and the water conservancy diversion effect increases, and the mobile effect of air current is better, is difficult for taking place the vortex more.
The number of the flow guide ribs is too small, rectification constraint on airflow is low, the number of the ribs is increased, rectification effect can be improved, turbulent flow is reduced, and air quantity is increased. However, the number of the ribs occupies the flow area in the flow guide ring, so that the number of the ribs needs to be reasonably controlled, the flow guide effect of the ribs and the influence on the flow area can achieve better balance, and preferably, the number of the flow guide ribs is 10-30.
After setting up the water conservancy diversion rib on the internal perisporium of circle body 1 of water conservancy diversion circle, because the water conservancy diversion effect of water conservancy diversion rib, make the air current of flowing through the water conservancy diversion circle flow and be nearly on a parallel with the rib pitch arc, and along with the increase of rib quantity N, the trend that this kind of air current is on a parallel with pitch arc is big more, but the increase of rib quantity influences the air volume, consequently, it is 16 to get N optimum, thereby both can guarantee the restraint effect of water conservancy diversion rib to the air current, improve the stability that the air current flows, can avoid the increase of water conservancy diversion rib to cause great influence to the air volume again, guarantee the air current flow efficiency of water conservancy diversion circle.
The length of the flow guide part 2 along the axial direction of the ring body is equal to or less than the axial length of the ring body 1.
In the present embodiment, the axial length of the baffle 2 is L, and the axial length of the ring body 1 is H, where L is 80% to 100% H. The relationship between the axial length of the flow guide part 2 and the axial length of the ring body 1 is defined as the above relationship, so that the problem that the length of the flow guide part 2 is too short, airflow rapidly enters a large turbulent flow state after leaving the flow guide part 2, the flow guide effect is not obvious, the problem that the flow guide part 2 is inconvenient to process and has adverse effects on the subsequent installation of the flow guide ring when the length of the flow guide part 2 is larger than the length of the ring body 1 can be avoided.
The baffle 2 extends both axially and circumferentially of the collar 1 in a direction along the collar 1 from the first end to the second end.
In this embodiment, the flow guide member 2 does not extend along the direction parallel to the central axis of the ring body 1, but deviates along the circumferential direction, so that the whole flow guide member 2 can form a certain inclined included angle relative to the central axis, and in the process of flowing through the flow guide member 2, the air flow can form a certain spiral flow guide effect under the inclined flow guide effect of the flow guide member 2, so that the air flow has pre-swirl when entering the air duct through the flow guide ring, and the power coefficient and the reaction degree of the air flow are increased.
