Description

a vertical cabinet

technical field

The utility model relates to cabinet design technology, in particular to a vertical cabinet.

Background technique

Electronic equipment cabinets are generally made of cold-rolled steel plates or alloys. They are used to store computers and related control equipment. They can provide protection for storage equipment, shield electromagnetic interference, and arrange equipment orderly and neatly to facilitate future maintenance of equipment.

At present, for most cabinets, the electronic equipment placed there, such as computers, are working 24 hours a day, so in the design, in addition to considering the mechanical protection and electromagnetic compatibility of electronic equipment, heat dissipation must also be considered. .

In order to enhance the heat dissipation of the electronic equipment, a heat dissipation device is generally arranged in the cabinet. The heat dissipation device for electronic equipment generally adopts air-cooling technology, that is, the heat is discharged through the principle of rising hot air, and it is necessary to design a reasonable air duct and set up air inlets and outlets; forced air cooling technology can also be used, that is, driven by a power unit. The airflow removes the heat, and the power unit is usually an electric fan. At present, many air ducts for heat dissipation devices for electronic equipment are designed to go forward and out, that is, the air inlet is in the front and the air outlet is in the back. Of course, due to the principle of hot air rising, the air outlet will be slightly higher than the air inlet. In this way, It is more in line with the structure of the cabinet. The cabinet is generally designed with vent holes that are staggered in front and back, and the heat dissipation effect is better. However, some electronic equipment have a special structure. Right in and left out, that is, the air inlet is on the right and the air outlet is on the left.

The vertical cabinet is a common cabinet for installing electronic equipment. Its shape is generally much higher than the length and width, so it can be set up and down with multiple layers for placing multiple electronic equipment. But the problem that this brings to heat dissipation is: if the design directions of the cooling air ducts of the upper and lower electronic equipment are different, it will greatly affect the effect of heat dissipation. The air duct of the electronic equipment is right in and left out, so a large part of the hot air blown from the air outlet (left) on the lower layer will enter the air inlet (front) of the upper electronic equipment, because the hot air rises, the upper air inlet ( front) is negative pressure. In this way, the heat of the lower electronic equipment will enter the upper electronic equipment, superimposed with the heat generated by the upper electronic equipment, the temperature will rise sharply, the working environment of the upper electronic equipment will be deteriorated, and the work of the upper electronic equipment will be greatly affected.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

A vertical cabinet according to an embodiment of the utility model includes a frame and a panel assembled around the frame; the frame is provided with more than two cabinets arranged up and down, and each cabinet is provided with a heat dissipation An air inlet and an air outlet; in the middle of two adjacent cabinets, a blocking device is provided to block the airflow from the air outlet of the lower cabinet from entering the air inlet of the upper cabinet.

Here, the frame is generally assembled by profiles, such as aluminum profiles, angle steel, etc. The assembly method can be through welding, riveting and threaded connection, etc. way fixed on the rack;

Further, in order to facilitate the heat dissipation and dehumidification of the equipment inside the cabinet, the panel is generally provided with ventilation holes; and in order to facilitate the heat dissipation of the equipment in the cabinet, a heat dissipation device is also provided, that is, an air duct is designed on the chassis, that is, the air ducts located at both ends of the chassis Air inlet and outlet.

Specifically, due to the large space in the height direction, the vertical cabinet generally has multiple chassis arranged up and down for placing multiple electronic devices; however, limited to the structure of the equipment, the air ducts of some chassis are designed in the front and rear directions , such as forward and backward, some are designed in left and right directions, such as right in and left out; and when the chassis with different upper and lower air ducts are adjacent to each other, the heat dissipation effect of the electronic equipment in it is relatively poor; such as the upper layer The air duct of the chassis is front and back, and the air duct of the lower chassis is right in and left out, so a large part of the hot air blown from the air outlet (left) of the lower will enter the air inlet of the upper chassis, because the hot air rises, the upper The air inlet is negative pressure. This will cause the heat of the lower electronic equipment to enter the upper electronic equipment, superimpose with the heat generated by the upper electronic equipment, and the temperature will rise sharply, which will deteriorate the working environment of the upper electronic equipment and greatly affect the work of the upper electronic equipment;

Of course, in order to improve the heat dissipation effect, in addition to natural air cooling, it can also be forced air cooling, that is, a fan is installed in the air duct. It is common to install a hair dryer at the air inlet or a suction fan at the air outlet, and it will be selected according to the structure of the equipment. Suitable fan types, such as axial or centrifugal, are not described in detail.

However, no matter whether it is natural air cooling or forced air cooling, it cannot solve the above-mentioned problem that the heat of the lower equipment is superimposed on the upper equipment; , a blocking device is provided to prevent the airflow from the air outlet of the lower chassis from entering the air inlet of the upper chassis;

Here, the blocking device is aimed at the situation that the air outlet of the lower layer is very close to the air inlet of the upper layer, that is, the direction of the air ducts of the upper and lower layers is inconsistent, and the hot air flow of the air outlet of the lower layer is prevented from entering the air inlet of the upper layer directly or quickly. , so that the hot air from the air outlet of the lower layer cannot enter or enter the air inlet of the upper layer in a detour, so that the heat of the electronic equipment on the lower layer will not be brought into the electronic equipment on the upper layer.

If the direction of the air passage of the upper and lower floors is the same, then the air outlet of the lower floor and the air inlet of the upper floor are far away from each other, so there is no need to adopt the blocking device of the embodiment of the present invention.

The two sides of the second partition in the width direction are respectively attached to the inner wall of the first panel and the outer wall of the lower chassis, the upper end of the second partition is attached to the bottom surface of the first partition, and the lower end is attached to the bottom surface of the first partition. The lower extension is greater than the height of the lower chassis.

In addition, since the chassis is fixed on the rack, if the four sides of the chassis are not aligned with the outer surface of the rack, the shape of the first partition needs to be adjusted accordingly, such as "concave" or "convex". The glyph, which is relatively sealed, will not be described in detail.

In order to explain more clearly, according to the direction of the air duct of the upper and lower chassis, if the upper level is forward and then out, and the lower level is right in and left out, then the blocking device is set on the left side of the cabinet, so that the airflow from the air outlet of the lower chassis Just can't flow up and forward; Effectively block the airflow of the air outlet of the lower chassis from entering the air inlet (front) of the upper chassis;

If the upper layer is right-in and left-out, and the lower layer is forward-backward, the blocking device is set at the back of the cabinet, so that the airflow from the air outlet of the lower chassis cannot flow upward and to the right; effectively blocking the airflow of the air outlet of the lower chassis Air intake into the upper chassis (right).

In the second type, the first partition is arranged in the space between the second panel of the cabinet and the upper chassis, the second panel is opposite to the air inlet of the upper chassis, and the first partition is horizontal place;

The lower end of the second partition vertically intersects the end of the first partition close to the air outlet of the lower chassis, and the upper end of the second partition extends upwards to a height greater than that of the upper chassis;

Specifically, the two ends of the width direction of the first partition are attached to the inner wall of the second panel and the outer wall of the upper cabinet respectively, and the two ends of the length direction of the first partition are respectively attached to the the inner wall of the other side panel intersecting with the second panel in the cabinet;

Wherein, the blocking device is fixed in the cabinet in a detachable manner. In this way, the position can be flexibly adjusted according to the position of the air outlet and air inlet of the upper and lower chassis;

Further, the detachable way may be screw fastening. Screws are common fasteners, which are easy to implement and low in cost.

Wherein, the first partition board and the second partition board are also assembled together in a detachable manner, of course, they can be fixed in the cabinet after being assembled, or can be fixed separately.
