The discharge structure of a kind of automobile air conditioning box evaporator core bottom
Technical field
The utility model belongs to air conditioning for automobiles design and fabrication technical field, relates to the design of automobile air conditioning box, is the discharge structure of a kind of automobile air conditioning box evaporator core bottom.
Background technology
Engineering automobile is an important kind in automobile.Due to the general working environment more complicated of Engineering automobile, sometimes under the severe working condition of environment, work, therefore, will be higher than other automobiles to the requirement of the air-conditioning of installing on Engineering automobile.The position of the evaporator core of air conditioning for automobiles routine is (referring to the Fig. 1) that is partial to open by design at present, at air-conditioning box housing 11, near the position of evaporator core bottom 12, be open, because expansion core surface has solidifying water generates, so evaporator core bottom 12 is the maximum position of air conditioning for automobiles ponding often, therefore, in this position, be provided with cavity 13 and osculum 14.But the discharge structure of existing automobile air conditioning box evaporator core bottom is under some operating mode, part ponding can spill under row's wind action, enters distributor box and even can be splashed into driver's cabin, the comfortableness that impact is driven and taken.
Utility model content
The purpose of this utility model is to address the above problem, the discharge structure of a kind of automobile air conditioning box evaporator core bottom is provided, in cavity bottom the evaporator core of easy ponding, increase water-retaining structure, even if also can make ponding under special operation condition discharges smoothly from the osculum of automobile air conditioning box evaporator core bottom, make ponding can not be splashed in air-conditioning box or be splashed into driver's cabin under wind action row, make the environment driving and take better.
For achieving the above object, the utility model has adopted following technical scheme.
The discharge structure of a kind of automobile air conditioning box evaporator core bottom, comprise air-conditioning box housing, evaporator core bottom, cavity, osculum, it is characterized in that, 13mm~15mm is improved in evaporator core bottom, the space of evaporator core two bottom sides and described air-conditioning box housing is increased, and described cavity also increases simultaneously; In the cavity increasing, a water fender is set; Described water fender is up-narrow and down-wide hierarchic structure, contain top layer, fixed edge, water guide limit and breach, described water fender is affixed by lower end and the described air-conditioning box housing of described fixed edge, and evaporator core bottom is set on water fender top layer, on described water guide limit, some breach is set.
Further, described water fender adopts metal plate punching structural member.
Further, the water fender of described hierarchic structure, described in it, the inclination angle of fixed edge and described water guide limit and described top layer is 52 °.
Further, described water guide limit is provided with at least three breach.
Further, described breach is of a size of 50 * 10mm, and arrangement pitches is 50mm, and inclination angle is 52 °.
The good effect of the discharge structure of a kind of automobile air conditioning box evaporator core of the utility model bottom is:
(1) evaporator core bottom is suitably improved, the space of evaporator core bottom periphery and air-conditioning box housing is increased, in cavity bottom the evaporator core of easy ponding, increase the water fender that has water guide function, not reducing in evaporator core bottom and the internuncial situation of air-conditioning box housing, guaranteed better transmissibility.
(2) adopt water fender can support evaporator core bottom, have again good water guide function, meet the requirement of using in automobile air conditioning box evaporator core bottom cavity.
(3) the results show: even if discharge structure of the present utility model also can make ponding discharge smoothly from the osculum of automobile air conditioning box evaporator core bottom under special operation condition, do not have ponding to spray from air outlet, effectively improved automobile, especially Engineering car steering and the comfortableness taken.

The specific embodiment
Below in conjunction with accompanying drawing, further explain the specific embodiment of the discharge structure of a kind of automobile air conditioning box evaporator core of the utility model bottom, but be noted that enforcement of the present utility model is not limited to following embodiment.
Referring to Fig. 2.A discharge structure for automobile air conditioning box evaporator core bottom, comprises air-conditioning box housing 21, evaporator core bottom 22, cavity 23, osculum 24 and water fender 25.The utility model need to be done the adjustment of structure: 13mm~15mm is improved in evaporator core bottom 22, the space of evaporator core 22 both sides, bottom and described air-conditioning box housing 21 is increased, described cavity 23 also increases simultaneously.A water fender 25 is set the cavity 23 increasing is interior.Described water fender 25 is up-narrow and down-wide hierarchic structure (referring to Fig. 3), contain top layer 26, fixed edge 27, water guide limit 28 and breach 29, both, on described top layer 26 both sides, be (52 ° of inclinations angle) up-narrow and down-wide stairstepping and be obliquely installed fixed edge 27 and water guide limit 28.Described water fender 25, by lower end and the described air-conditioning box housing 21 affixed (welding) of described fixed edge 27, arranges evaporator core bottom 22 on water fender 25 top layers 26, and three breach 29 are set on described water guide limit 28.Described breach 29 is of a size of 50 * 10mm, and arrangement pitches is 50mm, and inclination angle is 52 °.
Described water fender 25 can adopt metal plate punching structural member, makes its firmness better.
The foregoing is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
