Description

Technical Field

[0001] The invention relates to a vertical double air curtain cabinet. Background Art

[0002] On the market, such as Figure 1-Figure 3 As shown, there are two types of vertical air curtain cabinets, single air curtain cabinet and double air curtain cabinet, including foam boat bottom 1; foam back plate 2; external air curtain system 3; foam top plate 4; external air curtain outlet 6; internal air curtain outlet 7; shed column 8; layer plate 9, wherein the double air curtain cabinet has two forms: form a - the air duct of the air curtain is on the inner side of the foam layer; form b - the air duct of the inner air curtain is on the inner side of the foam layer; the air duct of the outer air curtain is on the top of the outer side of the foam layer. The existing technology and its disadvantages are as follows:

[0003] Form a: The outer air duct occupies the space inside the cabinet, reducing the effective volume inside the cabinet; the load-bearing parts inside the cabinet often need to cross the outer air duct to be fixed on the foam layer; due to space limitations, using one set of fans cannot accurately achieve air volume distribution;

[0004] b form: the outer air curtain inhales the ambient air, and there is more heat exchange between the inner and outer air curtains; the temperature difference between the inner and outer air curtains is large, and condensation is easy to occur at the connection between the inner and outer air outlets;

[0005] In addition, outer air curtains of types a and b cannot be added to single-layer air curtain cabinets. Summary of the invention

[0006] The present invention mainly solves the problems existing in the above-mentioned prior art and provides a vertical double air curtain cabinet, including a vertical double air curtain cabinet, characterized in that it includes: a foam layer insulation structure, including a foam boat bottom, a foam back and a foam top; an inner layer air duct, fixed on the inner side of the foam layer insulation structure; a layer plate, arranged on the inner layer air duct; an outer air curtain fan, including an outer air curtain fan support, under the outer air duct, behind the outer air duct and on the outer air duct, installed on the outer side of the cabinet body foam layer insulation structure.

[0007] Optionally, the static pressure chamber of the external air duct further includes a lampshade connecting plate fixed on the top of the foam.

[0008] Optionally, it also includes left, middle and right lampshade connecting end plates, which are supported between the lampshade connecting plate and the middle of the lampshade connecting plate.

[0009] Optionally, it also includes a static pressure chamber cover, which is fixed on the lampshade connecting plate and the foam top and is connected to the external air duct.

[0010] Optionally, the lampshade connecting plate is provided with a row of rectangular holes, and a plurality of fixing holes are provided on the folded edge connected to the lampshade connecting plate; the rectangular holes can make way for fixing screws to fix the lampshade connecting plate.

[0011] Optionally, a honeycomb support is further included, which is fixed on a lampshade plate, and a row of rectangular holes is formed on the lampshade plate, and airflow can pass through the rectangular holes to reach the honeycomb.

[0012] Optionally, the honeycomb support has an angle, equivalent to an inner chamfer, which can give way to the 90-degree straight edge of the honeycomb and make the component have a rebound effect, so that the honeycomb is reliably fixed on the lampshade plate.

[0013] Optionally, the rear side of the external air curtain fan support has an angled flange with a chamfer, which can be inserted when connected to the lower part of the external air duct; the front side of the external air curtain fan support has another angled flange, which can be connected and fixed to the bottom of the foam boat. The flange and the flange can make the external air curtain fan support easy to remove when repairing the fan.

[0014] Optionally, it also includes a skirt board, a plurality of inclined ventilation holes are opened on the upper part of which, and the cooler air flow overflowing from the cabinet passes through the ventilation holes and enters the outer air duct.

[0015] The above structure of the present invention is different from the pure inner double air curtain cabinet of type a and the outer double air curtain cabinet of type b with pure ambient wind. It has the same volume and load-bearing capacity as the single air curtain cabinet, but has an independent inner air curtain, which reduces the load inside the cabinet and makes it difficult for condensation to form between the inner and outer air curtains. An outer air curtain can be added to the single air curtain.

[0016] The structural form of the present invention has the following advantages:

[0017] 1. The internal structure of the air curtain cabinet is the same as that of the single air curtain cabinet, and the volume remains unchanged;

[0018] 2. The structure of the shelves and columns is the same as that of the single air curtain cabinet, and the load-bearing capacity remains unchanged;

[0019] 3. The air duct of the inner air curtain is the same as that of the single air curtain cabinet, and there is no interference with the outer air curtain due to the shared fan;

[0020] 4. The external air curtain inhales the overflow air of the cabinet, the temperature of which is lower than the ambient temperature, and the load inside the cabinet is reduced;

[0021] 5. The temperature difference between the inner and outer air curtains is small, and condensation is not easy to occur between the outer air curtains;

[0022] 6. It can be added to the original single-layer air curtain cabinet to form a double air curtain. BRIEF DESCRIPTION OF THE DRAWINGS
