Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment.

In description of the present utility model, it should be noted that term " interior ", " outward ", " on ", D score, "left", "right" It is with under air-cooled refrigerating equipment normal operating condition in the orientation indicated or position relationship, defines relative to the position of user , it is for only for ease of description this utility model and simplifies description rather than instruction or imply that the device of indication or element are necessary There is specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.

Refering to Fig. 2-Fig. 6, it is an embodiment of the air channel structure of the air-cooled refrigerating equipment that this utility model is proposed, this Air-cooled refrigerating equipment in embodiment is refrigerated display cabinet, can also be wind cooling refrigerator etc. in other embodiments.Air-cooled cold preservation sets For including casing and being positioned at cold room 1 and the air channel structure of casing, air channel structure has the return air inlet connected with cold room 2 and air outlet 3, also there is in air channel structure fan 4, vaporizer 5；Wherein return air inlet 2 is positioned at the upper front end of cold room 1, Air outlet 3 is positioned at the upper rear end of cold room 1, and the air-out direction of air outlet 3 vertically downward, and is located at the rear wall 11 of cold room 1 Place, namely from the cold wind of air outlet 3 blowout, flows downward along rear wall 11, blows to bending flow forward behind bottom, then to upstream Move and return in return air inlet 2.

In the present embodiment, participating in shown in Fig. 2 and Fig. 3, the air channel structure of air-cooled refrigerating equipment also includes being arranged on air outlet 3 The air duct board 6 at place, air outlet 3 is divided into before and after's two parts by air duct board 6 so that from air outlet 3 cold wind out by air duct board 6 It is divided into before and after two part, blows to bottom from the cold wind of the rear portion of air outlet 3 blowout along rear wall 11 and air duct board 6, then bending is forward Flowing, then flow up and return in return air inlet 2, front part cold wind blows to the front portion of cold room 1 and arrives return air inlet 2；In air channel Plate 6 is provided with multiple guide vane 61 extended forward, and guide vane 61 is horizontally disposed with, and namely guide vane 6 is suitable to air outlet 2 Part air-out guides return air inlet 2 direction；So from the cold wind of the anterior blowout of air outlet 3, along the front end face of air duct board 6 to dirty Dynamic, arrive the cold wind of guide vane 61, through the drain flow forward of guide vane 6, arrive the front end of cold room 1 bending afterwards upwards Flowing into return air inlet 2, this part cold wind arrives return air inlet 2 through shorter path so that the temperature near return air inlet 2 reduces, and carries Temperature uniformity in high cold a surname room 1, is conducive to accelerating the rate of cooling of load.

In the present embodiment, air duct board 6 extends along the air-out direction of air outlet 3, and namely air duct board 6 is downward along air outlet 3 It is vertically arranged, flows along air duct board 6 from the cold wind of air outlet 3 blowout；Air duct board 6 be arranged in parallel with rear wall 11, air duct board 6 with after The extension air duct connected with the rear section of air outlet 3 is formed so that from the cold wind of air outlet 3 rear section blowout along prolonging between wall 11 Stretch air channel to flow downward.

In the present embodiment, see shown in Fig. 2 and 6, so that the both sides of extension air duct are closed, the left and right two of air duct board 6 Side has the flanging 62 extended back, and flanging 62 is connected with rear wall 11, it is to avoid the cold wind in extension air duct is in the lateral direction Flowing, improve the air quantity that flows downward of cold wind.Outward extending flange 63, flange it is respectively equipped with in the end of two flangings 62 63 are fixed on rear wall 11, by arranging flange 63, air duct board 6 are fixed on rear wall 11, increase stablizing of air duct board 11 Property.

In the present embodiment, air outlet 3 is divided into two parts that anteroposterior dimension is equal by air duct board 6, namely air outlet 3 The distance of fore-and-aft direction is equal to two times of the air duct board 6 spacing with rear wall 11.In other embodiments, air duct board 6 can also will go out Air port 3 is divided into the unequal two parts of size.

In the present embodiment, shown in Figure 4, air duct board 6 is provided with multiple guide vane 61 extended forward, guide vane 61 In the vertical direction interlaced arrangement, concrete, guide vane 61 is provided with multiple rows of along the above-below direction of air duct board 6, often arranges parallel Show multiple guide vane 61, guide vane 61 interlaced arrangement of two rows；So be conducive to improving the air quantity arriving guide vane 61 Uniformity, improve further the temperature uniformity in cold room 1.Reinforcement 65 it is provided with between guide vane 61 and air duct board 6, Reinforcement 65 is fixing with the lower surface of guide vane 61 to be connected, and the effect of reinforcement 65 is to reinforce guide vane 61, increases guide vane 61 Structural strength.

In the present embodiment, see shown in Fig. 2, Fig. 4 and Fig. 5, be vertical direction from the cold wind of the anterior blowout of air outlet 3, Guide vane 61 is horizontal direction, impacts cold wind the most all bending forward, the cold wind under the drain of guide vane 61 of guide vane 61 Impulsive force for guide vane 61 is excessive, may send noise；In order to buffer the impact for guide vane 61, on air duct board 6 Offering the through hole 64 identical with guide vane 61 width, guide vane 61 is positioned at the downside of through hole 64, guide vane 61 and through hole 64 phase Even；So make a part of cold wind impacting on guide vane 61 can be entered the rear side of air duct board 6 by through hole 64, namely In entrance extension air duct, being conducive to the impact reducing cold wind for guide vane 61, what reduction cold wind impact guide vane 61 sent makes an uproar Sound；And by arranging through hole 64, the cold wind in extension air duct can also flow to the front of air duct board 6 by through hole 64, so Can ensure that the pressure flowing through the forward and backward cold wind of air duct board 6 is identical, it is to avoid the noise produced due to pressure reduction.

The above, be only preferred embodiment of the present utility model, is not that this utility model is made other form Restriction, any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as equivalent The Equivalent embodiments of change.But every without departing from technical solutions of the utility model content, real according to technology of the present utility model Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still falls within the guarantor of technical solutions of the utility model Protect scope.
