The specific embodiment
Shown in Fig. 1-9, technical scheme provided by the present invention is, wrap up by air conditioner housing, the inner gas channel that forms of described air conditioner housing (1), be provided with centrifugal blower (2), evaporator core (3), blender door (5), wind-mixer (7), heater core (6), air outlet (20) etc. along air channel, be provided with the wind-mixer (7) that makes hot and cold air-flow change direction between described blender door 5 and the air outlet 20; Described wind-mixer 7 is arranged on the position of cold and hot mixed zone, blender door 5 backs, and the wind-mixer that is installed in described air-conditioner is installed on the locating hole 16; Described wind-mixer 7 comprises dividing plate, membrane support muscle 14, and described dividing plate is adjustable dividing plate; Described dividing plate comprises streamlined dividing plate 8 and/or flat type dividing plate 9, and described streamlined dividing plate 8 and flat type dividing plate 9 are connected as one by flat board, and two kinds of blades are unified design thickness and are 1.5-2.2mm; Described streamlined dividing plate 8 and the 9 staggered combinations of flat type dividing plate form hot and cold air channel respectively, and the air channel air inlet is of a size of between the 28-38mm, and inwardly being dried by curved slab simultaneously in two air intake air ports, and locates to carry out in the middle of curved slab to mix; The shape-designing of streamlined dividing plate 8 is followed smoothness, reduces windage and certain linear variation principle is arranged on the described wind-mixer 7, and the power curve of walking that specifically constitutes curved surface is the curves in 3-5 rank, and curvature changes evenly; Described wind-mixer 7 hot and cold gas channels are 3-10/part altogether, and each moulding dividing plate adds up to 6-20, and the dividing plate altitude range is 60mm-200mm.
Wind-mixer 7 effects provided by the present invention are to shunt by dividing plate, the shunting of generation heat, reach heat balance, finally finish the temperature effect of uniform, Fig. 7 does not use the air-flow of wind-mixer 7 to move towards floor map for certain case, under the state that does not have wind-mixer 7, hot and cold air-flow PARALLEL FLOW does not have effective heat exchange; Fig. 8 uses the air-flow behind wind-mixer 7 for this case and moves towards floor map, use wind-mixer 7 after, the mutual blending of hot and cold air-flow, heat fully mixes, temperature is at air outlet 20 uniformities.
As shown in Figure 2, have two kinds of dividing plates on wind-mixer 7 structures: a kind of for flat type dividing plate 9---9 indications among the figure are, another kind of each dividing plate is connected as one by flat board for streamlined dividing plate 8---8 indications among the figure are, and two kinds of blades are unified design thickness and are 1.8mm; Guarantee that by reinforcement 17 air port is indeformable simultaneously.
Two kinds of staggered combinations of dividing plate form hot and cold air channel respectively, and the air channel air inlet is of a size of about 33mm, are inwardly dried by curved slab simultaneously in two air intake air ports, and locate to carry out in the middle of curved slab to mix, and specifically can illustrate referring to Fig. 9.
On the physical dimension, can be according to intensity or process conditions, with wind-mixer 7 one-shot formings or sectional forming, but do not influence the result of use of wind-mixer 7.
Wind-mixer 7 fixed forms determine according to the peripheral structure condition, but are basic principle not change the dividing plate form, and 16 are depicted as specific cases and use and install and fix a little among Fig. 4.
Dividing plate density of wind-mixer 7 (being the dividing plate number on every wind-mixer 7, individual/part) or spacing---among Fig. 3 shown in 15, need adjust, can reach re-set target according to different air-conditioning internal gas flow states, and incomplete uniformity.
The dividing plate height of wind-mixer 7 can inhomogeneous unanimity, needs according to the stream condition adjustment, and dividing plate of the left and right sides shown in Fig. 3 and internal partition height are all inconsistent.
The shape-designing of streamlined dividing plate 8 is followed smoothness, reduces windage and certain linear variation principle is arranged on the wind-mixer 7, and the power curve of walking that specifically constitutes curved surface is the curves in 3 ~ 5 rank, and curvature changes evenly.
Installing and using of technical solution of the present invention:
Use wind-mixer 7 effects to show through a plurality of projects, wind-mixer 7 is placed the key area of hot and cold air mixing, and simultaneously according to each air-conditioner housing internal structure, install and fix mode and stream condition is adjusted wind-mixer 7 moulding, can reach the enhanced heat exchange effect, make air outlet 20 temperature uniformities.
By the case practice, Figure 10 uses the contrast of wind-mixer 7 front and back air outlets 20 temperature uniformity effects for certain air-conditioning.Wherein Figure 10 a is air outlet 20 temperature conditions of previous status, and as can be seen from the figure, because cold and hot wind fully do not mix, differ greatly with the temperature of blowing pin/blow air port, back in the face that the blows air port that causes this air-conditioning, and blows pin/the blow abnormal conditions that the back temperature also has fluctuation; For head it off, we have increased a wind-mixer 7 in cold and hot Mixed Zone, and after the reinforcement mixing by wind-mixer 7, Figure 10 b is for using the back result of the test.Contrast is used the front and back effect as can be seen, and the HVAC behind the use wind-mixer 7 blows the face air port and blows pin, and the temperature spread of blowing the air port, back reduces greatly, and temperature changing trend is basically identical also, can satisfy user's instructions for use.
Wind-mixer 7 design concepts provided by the present invention also comprise the content of the following aspects:
1. wind-mixer 7 moulding: the resulting structure of wind-mixer 7 is straight dividing plate and streamlined dividing plate 8, can not change on the former air-conditioner housing basis, uses this part to realize promoting the effect of temperature homogeneity.
2. wind-mixer 7 physical dimensions: the structure and specification of wind-mixer 7 need just can accomplish the end in view according to different housings and the adjustment of internal gas flow state thereof, on adjusting, the density of runner dividing plate (every wind-mixer 7 on number of channels), highly be decisive factor, wind-mixer 7 hot and cold gas channels are 3 ~ 10/part altogether, each moulding dividing plate adds up to 6 ~ 20, the dividing plate altitude range is 60mm ~ 200mm, and thickness range is at 1mm ~ 2mm.
3. the scope of application: this wind-mixer 7 uses on single zone and multizone air-conditioning of air conditioning for automobiles.
