Problems solved by technology

However, the windshield has a great influence on the flow of wind, which will increase the air resistance in the automobile air conditioner distributor. On the one hand, the noise will increase, and on the other hand, the air volume will decrease significantly.
Therefore, the actual application effect of this existing improved technical solution is not good

Embodiment Construction

[0032] Such as image 3 As shown, a specific embodiment of the automobile air-conditioning distribution box with low flow resistance air guide of the present invention mainly includes a box body, a heating unit 5 and a refrigeration unit 6 . A defrosting tuyere 1, a face blowing tuyere 2, and a foot blowing tuyere 3 are arranged on the box body, and a temperature mixing damper 4 is arranged in the box body. In the present invention, a low-flow-resistance air-guiding element 7 is further provided on one side of the temperature-mixing damper 4 , and the low-flow-resistance air-guiding element 7 has characteristics of relatively low wind flow resistance.

[0033] Such as Figure 4 As shown, in this embodiment, the low-resistance air guide 7 includes four air guides 71 , 72 , 73 , 74 and a connecting piece 78 . The main function of the connecting piece 78 is to fix the aforementioned four air guiding bodies, and to fix the low flow resistance air guiding element 7 with the housi...

Abstract

The invention discloses an automobile air conditioning distribution box with a low-flow-resistance air guide piece. The automobile air conditioning distribution box comprises a box body, a heating unit and a cooling unit, wherein a defrosting ventilation orifice, a face blowing ventilation orifice and a foot blowing ventilation orifice are formed on the box body; a temperature-mixing air door is arranged in the box body; the low-flow-resistance air guide piece is arranged on one side of the temperature-mixing air door; an air guide channel is formed in the low-flow-resistance air guide piece and is provided with an air guide inlet facing to the heating unit, a first air guide outlet facing to the defrosting ventilation orifice, and a second air guide outlet facing to the surface blowing ventilation orifice; and the low-flow-resistance air guide piece has low-flow-resistance appearance the windward side of which faces to the cooling unit. As the automobile air conditioning distribution box adopts the structure design, cool air and hot air can be mixed better in the automobile air conditioning distribution box, and the temperature difference of the orifices is reduced; and simultaneously, the air flow resistance in the whole automobile air conditioning distribution box does not increase obviously, so that the comfortableness of an automobile air conditioner is improved remarkably.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner distribution box with a low-flow-resistance wind guide. Background technique [0002] The automobile air conditioning box is an assembly that includes the air intake unit, blower unit, air purification unit, heating unit, refrigeration unit, air volume distribution unit, etc. of the automobile air conditioner, and is combined according to certain rules. [0003] Among them, the air volume distribution unit is the part connected with the air outlet of the cab. The refrigerated or heated air is finally sent from each air outlet of the automobile air conditioning distribution box to the cab of the automobile according to the required distribution ratio, and the temperature and humidity are adjusted, as well as defrosting and defogging to ensure vision and driving safety. [0004] Usually, the automobile air conditioning distribution...
