Description

Technical Field

[0001] The utility model relates to the technical field of electric control equipment, in particular to a negative pressure driven fixed-point cooling type electric control cabinet. Background Art

[0002] Most existing electrical control cabinets are designed with a single air inlet at the bottom and a single air outlet at the top.

[0003] The forced airflow is controlled by the method of bottom-in and top-out. The low-temperature air sucked in from the bottom will increase in temperature after passing through the lower heating components, affecting the heat dissipation of the upper heating components. Due to the settling of dust, the air in the lower part of the room often has a high dust content, which is easy to accumulate in large quantities in the chassis, affecting the operation of the components. Utility Model Content

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a negative pressure driven fixed-point cooling electric control cabinet, comprising a base, a bracket is arranged on the base, and an air inlet component is arranged on the side wall of the bracket;

[0005] The air inlet assembly includes: a door, an air inlet part, a display screen, an exhaust fan, an exhaust hole and a top cover;

[0006] The door is arranged on the side wall of the bracket, the air inlet is arranged on the door, the display screen is arranged on the air inlet, the exhaust fan is arranged on the top of the bracket, the exhaust hole is arranged on the top cover, and the top cover is arranged on the top of the bracket;

[0007] The air inlet portion comprises: a shaping structure layer, a uniform air inlet layer, reinforcing ribs and a fixed-point air inlet layer;

[0008] The modeling structure layer, the uniform air intake layer, the reinforcing ribs, the fixed-point air intake layer and the display screen are sequentially spliced ​​and assembled.

[0009] Preferably, the shaping structure layer and the uniform air intake layer are both mesh structures, the reinforcing ribs are rectangular frame structures, and the fixed-point air intake layer is assembled with the display screen.

[0010] Preferably, an electrical installation plate is provided on one side of the bracket.

[0011] Preferably, exterior panels are provided on opposite side walls of the bracket.

[0012] Preferably, the outer side wall of the base is provided with a frame.

[0013] Beneficial Effects

[0014] The utility model provides a negative pressure driven fixed-point cooling electric control cabinet, which has the following beneficial effects: the exhaust fan is arranged at the top and the number and position are flexibly changeable, which can adapt to various different scenes. Compared with the traditional front air intake and front air exhaust design, the airflow organization is better, and the airflow can be better guided to the heating elements. The airflow distribution is designed according to the actual heat dissipation needs in the control cabinet. The holes at the bottom are slightly larger and the holes at the top are slightly smaller to prevent a large amount of air from short-circuiting and losing from the top.

[0015] The main air inlet is at a high distance from the ground, which not only meets the cooling requirements of the lower part, but also does not attract a large amount of dust from the ground into the cabinet, thus extending the life of internal components and reducing the frequency of cleaning.

DETAILED DESCRIPTION

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] Example: See Figure 4 In order to adapt to various scenarios, compared with the traditional design of front air intake and exhaust, the airflow organization is better, and the airflow can be better guided to the heating element. The airflow distribution is designed according to the actual heat dissipation requirements in the control cabinet. The lower hole is slightly larger and the upper hole is slightly smaller to prevent a large amount of air from short-circuiting from the upper part. The specific working principle is as follows, including a base, a bracket is arranged on the base, and an air intake assembly is arranged on the side wall of the bracket;

[0023] The air inlet assembly includes: a door, an air inlet part, a display screen, an exhaust fan, an exhaust hole and a top cover;

[0024] The door is arranged on the side wall of the bracket, the air inlet is arranged on the door, the display screen is arranged on the air inlet, the exhaust fan is arranged on the top of the bracket, the exhaust hole is arranged on the top cover, and the top cover is arranged on the top of the bracket;

[0025] The air inlet portion comprises: a shaping structure layer, a uniform air inlet layer, reinforcing ribs and a fixed-point air inlet layer;

[0026] The modeling structure layer, the uniform air intake layer, the reinforcing ribs, the fixed-point air intake layer and the display screen are sequentially spliced ​​and assembled.

[0027] In the above solution, the shaping structure layer and the uniform air intake layer are both mesh structures, the reinforcing ribs are rectangular frame structures, and the fixed-point air intake layer is assembled with the display screen.

[0028] In the above solution, an electrical installation board is provided on one side of the bracket.

[0029] In the above solution, exterior panels are provided on opposite side walls of the bracket.

[0030] In the above solution, the outer side wall of the base is sleeved with a frame.

[0031] The main structure consists of a frame, a top cover (with exhaust holes), an exterior panel, a fixed-point cooling multi-layer cabinet door, an electrical installation panel, an exhaust fan, etc. The frame is assembled from a base and a combined bracket, which is easy to assemble and has strong size adaptability.

[0032] Exhaust holes are arranged around the top cover, and multiple exhaust fans are arranged inside the exhaust holes. The number and position of fans can be flexibly adjusted according to the actual installation position of the control cabinet and the heat generated by the internal components. For example, if the back is against the wall, the exhaust will be blocked, so no fan is installed on the back; if the side is close to other objects, no fan is installed on the side. The rear of the exhaust hole plate without fan is encapsulated with sheet metal.

[0033] The fixed-point cooling multi-layer cabinet door is composed of a shape structure layer, a uniform air intake layer, reinforcement ribs, a fixed air intake layer, and a display screen. The uniform air intake layer is a porous plate design, which stabilizes the airflow and reduces noise. The fixed air intake layer is customized with holes of different sizes and positions, and its position and size correspond to the heat-generating electrical components on the electrical installation board.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
