no. 1 approach

[0070] according to Figure 1a and 1b In the first embodiment shown in , the atomizing main channel 23 a is open on the diffuser 5 , in particular approximately at the center of the inlet 21 of the diffuser 5 , and is inside the diffuser 5 , thus at the inlet of the diffuser 5 The downstream of 21 is further divided into a plurality of atomizing sub-channels 23b, 23c.

[0071] refer to Figure 1a and 1b The illustrated example, in a non-limiting manner, the atomizing flow passage 23a can be further divided into: a predetermined number of atomizing lateral secondary flow passages 23b, in this example, four atomizing lateral secondary flow passages 23b; Atomization central sub-channel in the center of the atomization lateral sub-channel 23b. The atomization center sub-flow channel 23c is further arranged substantially in the center of the diffuser 5 .

[0072] According to this embodiment, the spray outlet 19 ′ terminating in the atomizing central secondary flow channel 23 c ...

no. 2 approach

[0077] exist Figure 2a-2c In the second embodiment shown, the difference from the first embodiment is that, according to the direction of flow path of the air flow loaded with droplets of atomizing liquid Fg, the main atomizing channel 23a is upstream of the diffuser 5 and thus in The upstream of the inlet 21 of the diffuser 5 is further divided into a plurality of atomizing sub-channels 23b, 23c.

[0078] This subdivision of the atomizing main channel 23a upstream of the diffuser 5 or this split airflow cooling device 1 provides a simpler solution for decoupling the first embodiment.

[0079] According to the example shown, in order to prevent stagnation of the atomizing liquid in the atomizing secondary channels 23b, 23c, the latter are not downwards with respect to the longitudinal axis A of the diffuser 5 before the outlets 19, 19' of the diffuser 5 tilt.

[0080] For this, as in Figure 2b As better seen in , the atomizing secondary flow channels 23b, 23c extend subst...

Abstract

The invention relates to an air flow refrigeration device (1), in particular for a passenger compartment of a motor vehicle. The air flow refrigeration device (1) comprises: a nebulizing unit (3) which is used for nebulizing liquid in the form of droplets, and an aerator (5) configured to diffuse at least one air flow to the passenger compartment of the vehicle and having a nebulization outlet (19') configured to deliver the nebulized liquid droplets into the at least one air flow to the passenger compartment. According to the invention, the aerator (5) comprises a plurality of nebulization outlets (19, 19'). The invention also relates to a heating, ventilation and / or air conditioning installation comprising such an air flow refrigeration device (1).

Description

technical field [0001] The invention relates to an airflow cooling device for a motor vehicle. The invention also relates to a heating, ventilation and / or air conditioning installation comprising such an air flow cooling device. Background technique [0002] In order to ensure the thermal comfort of the vehicle occupants, motor vehicles for example mostly generally have integrated ventilation and / or air-conditioning systems for establishing a lower temperature in the passenger compartment than the outside temperature. [0003] These ventilation and / or air conditioning systems circulate cooled air so that they provide thermal comfort to the vehicle occupants. A first disadvantage of this system is that the cooled air is dry. In addition, the areas at the rear of the passenger compartment are generally not well ventilated, so that they are not cooled well either. [0004] It should also be noted that not all vehicles are necessarily air-conditioned. [0005] To improve thi...
