Embodiment one：
It is illustrated in figure 5 a kind of wind cooling refrigerator of uniformity of temperature profile of the present embodiment, is filled on the rear wall of wind cooling refrigerator
Equipped with refrigeration air duct cover board 502, it is equipped with the Tibetan object room of upper and lower structures distribution in the front of refrigeration air duct cover board, which can
To be freezing chamber, refrigerating chamber, ice greenhouse or simple layer frame.Positioned at that Tibetan object of top layer in the wind cooling refrigerator of the present embodiment
Room is ice greenhouse 503, and the temperature control mode of the ice greenhouse 503 is fuzzy temperature control.It is arranged in the 503 corresponding front of ice greenhouse
There is the water dispenser water tank 505 on refrigerator door.
As depicted in figs. 1 and 2 for refrigeration air duct cover board 502, refrigeration air duct cover board on be provided with eight air outlets (101~
108), two air outlets 101,105 of the top are corresponding with the ice greenhouse of top layer in wind cooling refrigerator, in the two air outlets
101, it is removably fixed with wind-guiding block respectively on 105.
As shown in Figure 8 and Figure 9, air outlet exports for straight tube-like, and wind-guiding block includes curved slab 901, the curve of curved slab 901
Shape is that second-degree parabola removes the shape after half.The front end of curved slab 901 is equipped with head 801, and head 801 is annular shape,
The middle part of annulus is fixed in the front end of curved slab 901, the part for being located at 901 top of curved slab on head with before curved slab 901
End surrounds wind-guiding block front end exit 804.The lower recess 805 on head 801 is that material is blocked up and shrink in order to prevent, so just staying
The groove gone out.The size on head 801 be more than air outlet front port, peak at the front end of air outlet, head 801 upper edge side and
Both sides are extended back along side equipped with coaming plate 806, and coaming plate 806 is enclosed on the lateral wall of air outlet front end.
Curved slab 901 extends to air outlet inner end to back lower place bending, and downward barb is equipped in the rear end of curved slab 901
803,803 hook of barb is in the rear end that straight tube-like exports, to which wind-guiding block to be connected in air outlet.The right side of curved slab 901 is set
There are vertical fixed plate 802, the upper end of fixed plate to peak at the upper wall of straight tube-like outlet so that curved slab 901 cannot be rotated up,
So in use, barb 803 would not also be detached from the rear end of air outlet.
As shown in figure 5, being equipped with drive end bearing bracket 504 in the front end of ice greenhouse 503, the top of drive end bearing bracket 504 is upper with Tibetan object room
Gap 501 is equipped between wall.Flow trace 506 of the cold wind in ice greenhouse is illustrated in figure, when cold wind is by curved slab
After above, blow out, and move to the front upper place of air outlet from wind-guiding block front end exit 804, cold wind when encountering drive end bearing bracket 504,
Two parts will be divided into, a part of cold wind is flowed outwardly from gap 501 to be acted on the water dispenser water tank 505 in front, another portion
Divide the lower part for being back to hide object room 503 downwards.From flow trace 506 as can be seen that cold wind has flowed through the top of ice greenhouse under
Portion has also acted on water dispenser water tank 505, and temperature will be uniformly distributed.
It is determined through testing measuring temperature field distribution situation, when the area that the area of wind-guiding block front end exit 804 is air outlet
25%~35% when, temperature reaches national standard in the ice greenhouse of the present embodiment, and Temperature Distribution is the most uniform in refrigerator,
Advantageously reduce energy consumption.
Fig. 3 illustrates the flow trace 301 of cold wind when without wind-guiding block, and Fig. 4 illustrates cold after installing wind-guiding block
The flow trace 401 of wind, can significantly be compared.
Embodiment two：
It is illustrated in figure 6 a kind of wind cooling refrigerator of uniformity of temperature profile of the present embodiment, embodiment two and embodiment one
