In a specific embodiment, the present embodiment provides a heat exchanger air shower device, which may be a centrifugal humidifier. Specifically, the air shower device for the heat exchanger comprises a fan 1, an atomization tooth part and a liquid supply device 3. Other arrangements may of course be included.

The liquid supply device 3 is used for supplying liquid to the rotating part of the fan 1, so that the rotating part of the fan 1 can centrifugally throw out the liquid when rotating at a high speed. The rotating component of the fan 1 may be the impeller 14 of the fan 1, or may be the turntable 11 fixed opposite to the impeller 14, when the turntable 11 is set, the turntable 11 and the impeller 14 may be both fixed on the same rotation shaft, and the rotation shaft may be in driving connection with the main shaft of the motor 13, such as fixed connection or integral forming. The liquid supply device 3 is a pumping device, and can be connected with a municipal water supply system (tap water) to avoid using a pump body, wherein the pumping device can be a motor 13 independently arranged, and can also share the motor 13 with the fan 1. The liquid supply device 3 is used for supplying liquid to the rotating part of the fan 1, namely, mainly two situations are: in one case, the liquid supply device 3 is used for supplying liquid to the impeller 14 of the fan 1, and when the impeller 14 rotates at a high speed, the liquid is thrown out in a centrifugal direction and is thrown out around; alternatively, the liquid supply device 3 is used for supplying the liquid to the rotary disk 11 additionally arranged on the fan 1, and the rotary disk 11 rotates at a high speed along with the impeller 14 to throw the liquid.

The atomizing tooth part is used for being connected with liquid thrown out by the rotating part of the fan 1 in a windward mode so as to differentiate, when the rotating part rotates at a high speed, the liquid is thrown out from the rotating part in a centrifugal mode under the action of centrifugal force, the atomizing tooth part is arranged on a thrown-out path, so that the thrown-out liquid can enter the atomizing tooth part, and the atomized tooth part is beaten at a high speed so that the atomized tooth part can differentiate liquefied liquid particles, and the liquefied liquid particles are mainly crushed to form fine particles.

The impeller 14 of the fan 1 is used for blowing out droplets differentiated by the atomizing tooth parts to form a liquid-containing air body when rotating, and the impeller 14 of the fan 1 is used for pushing the air body at the air inlet side to the air outlet side when rotating. In the pushing process, the wind body flows to bring out liquid particles mixed in the wind body, so that a liquid-containing wind body is formed at the wind outlet side.

Wherein the atomizing tooth portion includes movable teeth 2, and movable teeth 2 can be moved to adjust the circumferential direction tooth density of the atomizing tooth portion in the work position portion, so as to change the atomizing ability. Generally, in the set density range, the larger the circumferential tooth density is, the larger the number of teeth is, and the number of broken teeth is increased; conversely, the smaller the circumferential tooth density, the smaller the number of teeth, and the smaller the number of fractures. Of course, as the circumferential tooth density continues to increase beyond the set range, the amount of chipping does not increase because the teeth have been interfered with, and water accumulation may occur at this time, resulting in water mold realization.

And wherein the atomizing tooth portion is provided with movable teeth 2, there are mainly two modes: in the first mode, only the movable teeth 2 and the atomizing barrel 12 are arranged, the atomizing barrel 12 is fixed at a working position, the movable teeth 2 can enter and exit the working position, when the movable teeth 2 enter the working position, the movable teeth 2 are atomized, and when the movable teeth 2 move out of the working position, the atomizing barrel 12 is slightly crushed, liquid is hit on the surfaces such as a plane or a curved surface and splashed to form particles, and the movable teeth 2 can be a plurality of movable teeth 2 to enter and exit the working position respectively, so that the tooth density is further adjusted; the second way is that the atomizing tooth part is provided with a fixed tooth 4 and a movable tooth 2, and when the fixed tooth 4 and the movable tooth 2 are both in a working position, the tooth parts of the fixed tooth 4 and the movable tooth 2 are staggered to form a synthetic atomizing tooth with a tooth density larger than that of the fixed tooth 4.

In this heat exchanger is with wind drenching device, when using, according to the requirement of fog volume, can adjust whether movable tooth 2 is located the working position, and then change the circumference tooth density of working position. The circumferential tooth density of the working position is changed, the size and/or atomization amount of atomized particles can be correspondingly changed, the inner tooth density is increased in a certain range, the atomization amount is increased, and the atomized particles are reduced. After the size and/or the atomization amount of the atomized particles are changed, the liquid content and the liquid particle size distribution range in the liquid-containing air body can be correspondingly changed, so that the atomization requirement of a use state is further met, and the requirements of different heat exchange efficiency under different states are further met. In conclusion, the air shower device for the heat exchanger can effectively solve the problem that the heat exchange efficiency of the air shower device cannot be adjusted.

In some embodiments, the movable teeth 2 can move relative to the fixed teeth 4 along the axial direction so as to be capable of entering and exiting the working position, and the movable teeth 2 are staggered with the fixed teeth 4 when entering the working position. At this time, the movable teeth 2 can axially translate relative to the fixed teeth 4, for example, move in a direction away from the rotating component and move in a direction away from the air outlet, so as to separate from the working position. In this case, the fixed teeth 4 may include a ring gear and a tooth portion, and the tooth portion and the ring gear may be disposed in parallel in the radial direction or may be disposed in parallel in the axial direction.

When the first tooth portion and the second tooth portion are provided, at least the following two cases can be adopted. One of the situations is that the first tooth part and the second tooth part are axially arranged in parallel and are relatively fixed, only one driving device is needed at the moment, the driving end is fixedly connected with the first tooth part or the second tooth part, when the driving end moves to the first position, the first tooth part enters the working position, the second tooth part is separated from the working position, when the driving end moves to the second position, the second tooth part enters the working position, and the first tooth part is separated from the working position.
