Airflow guiding structure 10 typically can be used for the heating ventilation air-conditioning system (HVAC) of automobile.Heating ventilation air-conditioning system usually has There is heating or cooling device, the air in environment to be heated or cooled.The airflow guiding structure 10 is used for air-flow It is directed to one or more air stream outlets from one or more air flow inlets.Specifically, the airflow guiding structure 10 can be with Its air flow inlet receives heated or cooling air-flow, guiding air-flow advances along its gas channel and makes air-flow positioned at spy It positions the air flow outlet set and enters ambient enviroment, such as the passenger compartment of automobile, be adjusted with the temperature to passenger compartment.Air-flow The air flow inlet of guide structure, the quantity of air stream outlet and gas channel and arrangement can have diversified forms.

Typically, as shown in Figure 1, the air-flow from same air flow inlet 9 can be directed to two by airflow guiding structure 10 A different air stream outlet 7,8, the air stream outlet 7,8 can be (but are not limited to) two blow foot outlet or two faces of blowing go out Mouthful.

In the case of existing airflow guiding structure 10, due to different air stream outlets at a distance from air flow inlet not Together, therefore the gas flow temperature of different air flow outlets is different.By taking airflow guiding structure shown in FIG. 1 as an example, in heating mode Under, the analog temperature distribution map which generates is as shown in Figure 8.As can be seen from Figure 8, due to two air-flows Outlet 7,8 is different at a distance from air flow inlet 9, therefore the gas flow temperature at described two air stream outlets 7,8 differs greatly.According to The analog result, under specific entry condition, the temperature difference of two air stream outlets (being exported in this example to blow foot) makes up to 18 DEG C The comfortably experience for obtaining occupant is poor.

In addition, other reasons can also cause the temperature of different air flow outlets different, such as due to airflow guiding structure 10 Different gas channels there is different length, varying cross-section product, different location etc..

In order to reduce the Temperature Distribution difference between different air stream outlets to improve the comfort level of passenger, this practicality is new Type proposes a kind of novel airflow guiding structure 10, and the air-flow proposed to the utility model below in conjunction with attached drawing guides The preferred embodiment of structure 10 is introduced.

The airflow guiding structure 10 that the utility model is proposed may include air flow inlet, air stream outlet and gas channel.Its In, in the scheme that the attached drawing 1-3 of the utility model is shown, the tool of airflow guiding structure 10 there are one air flow inlet 9, air-flow from The air flow inlet 9 enters the public gas channel 1 of airflow guiding structure 10, and then along from 1 branch of public gas channel First gas channel 3 and the second gas channel 4 are advanced, and first gas channel 3 directs air flow to the first air stream outlet 7, Second gas channel 4 directs air flow to the second air stream outlet 8.Wherein second gas channel 4 can have and the first gas The different length of circulation road 3 or cross-sectional area.But the tool of the air flow inlet of the utility model, air stream outlet and gas channel Body quantity and specific configuration are not limited to this.

To solve the above-mentioned problems, the airflow guiding structure 10 that the utility model is proposed is designed such as, in certain air-flow Hatch frame 2 is set on the side wall 11 in channel, and the hatch frame 2 includes opening 6, and optionally includes flow guiding structure portion 5.Institute It is to be formed on the side wall 11 of gas channel to run through opening to state opening 6 so that the gas except gas channel can pass through institute Opening 6 is stated to enter inside gas channel.The flow guiding structure portion 5 is at least partly around the opening 6 and from the side wall 11 It is recessed inwardly.To form drainage channel 12, for guiding the air-flow entered from the opening 6 inside gas channel.It is preferred that Ground is as shown in Figure 4,5, 6, and the drainage channel 12 obliquely intersects with the gas channel.The flow guiding structure portion 5 can omit.

By the way that the hatch frame 2 is arranged on gas channel, the air-flow except gas channel can be inhaled into the gas Circulation road.As it was noted above, airflow guiding structure 10 is used to guide heated or cooling air-flow, that is, airflow guiding structure 10 The temperature of the air-flow of guiding is different from the temperature of ambient enviroment.It is described since surrounding air enters gas channel from hatch frame 2 The temperature of original air-flow can be changed in gas channel.By taking embodiment shown in Fig. 1-3 as an example, only the first gas channel 3 With hatch frame 2.Due to the presence of hatch frame 2, the gas flow temperature at the first air stream outlet 7 of the first gas channel 3 can With the temperature being changed to closer at the second air stream outlet 8.Fig. 9 is in its heating mode using air-flow shown in Fig. 1-3 The temperature profile generated in the case of guide structure 10.As can be seen that compared to the prior art shown in Fig. 8, this practicality is new The airflow guiding structure 10 that type is proposed enables to the gas flow temperature difference at two air stream outlets 7,8 to be substantially reduced.

Fig. 1-3 illustrates a feasible embodiment of airflow guiding structure 10, and Fig. 4-7 illustrates airflow guiding structure 10 Hatch frame 2 a variety of modifications.It should be noted that Fig. 4-7 is merely intended to displaying hatch frame 2, therefore in order to clearly rise See, gas channel has simplifiedly been depicted as to the square duct of rule in figures 4-7, but the utility model gas channel is necessarily Using this square duct, but the channel construction or any other feasible channel construction of Fig. 1 may be used.This practicality is new Type does not limit the concrete shape and construction of gas channel.

The opening 6 can have arbitrary shape or construction.For example, in the embodiment shown in fig. 4, opening 6 has big Cause square configuration；In the embodiment shown in fig. 6, opening 6 has generally circular shape；In the embodiment shown in fig. 6, it opens Shapes of the mouth 6 with general triangular；In Fig. 2 and embodiment shown in fig. 5, opening 6 has irregular shape.
