Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, specifically a power cabinet cooling device for power applications. Background Technology

[0002] A power cabinet is a type of control cabinet. A control cabinet is a closed or semi-closed metal cabinet or panel in which switching equipment, measuring instruments, protective electrical components, and auxiliary equipment are assembled according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger personal safety or the safety of surrounding equipment. During use, the electrical components inside the power cabinet generate a significant amount of heat over prolonged operation, especially in summer. If this heat is not dissipated in time, it can easily damage the internal instruments and equipment, affecting the power cabinet's use in the power system.

[0003] Most existing power cabinets currently use fans to ventilate and cool them. However, after prolonged use, dust from the air can easily enter the interior of the power cabinet. Dust adhering to the surface of the electrical equipment can easily cause short circuits and result in unnecessary losses. Therefore, we propose a power cabinet cooling device for electrical applications. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling device for power cabinets used in power applications, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power cabinet cooling device for power applications, comprising:

[0006] The power cabinet has a door at its front end and a cooling mechanism. The cooling mechanism includes a heat collection component and a cooling component. The heat collection component includes two heat collection covers, which are respectively fixedly welded to the side walls of the power cabinet. Multiple evenly distributed through slots are formed on the side wall of the power cabinet within the heat collection cover cavity. Heat dissipation fins are fixedly installed in these slots. Heat absorption plates are fixedly adhered to the inner walls of both sides of the power cabinet. The heat absorption plates are fixedly adhered to the multiple heat dissipation fins using thermally conductive adhesive. The cooling component includes a blower with an air inlet cover and an air duct. A T-junction is fixedly installed at the end of the air duct furthest from the blower. Two air supply pipes are fixedly installed on the T-junction, and the ends of the two air supply pipes furthest from the T-junction are respectively fixedly installed on the top walls of the two heat collection covers.

[0007] Preferably, a chiller is fixedly installed on the rear wall of the power cabinet on one side of the air inlet hood. Two connecting pipes are fixedly installed on the chiller, and the same serpentine circulation pipe is fixedly installed on the two connecting pipes. The serpentine circulation pipe is fixedly installed in the inner cavity of the air inlet hood.

[0008] Preferably, a controller is fixedly installed on the rear side wall of the power cabinet, and the controller is electrically connected to the blower and the refrigeration unit respectively via wires.

[0009] Preferably, a temperature sensor is fixedly installed on the inner wall of the top side of the power cabinet, and the temperature sensor is electrically connected to the controller via a wire.

[0010] Preferably, ventilation windows are provided on both sides of the power cabinet.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In use, the power cabinet dissipates heat only through the ventilation window during daily operation. When the internal temperature of the power cabinet reaches a certain level, the temperature sensor transmits a signal to the controller. The controller then activates the blower and the chiller. The chiller circulates coolant into the serpentine circulation pipe, thereby cooling the air passing through the air inlet shroud. The blower blows the low-temperature air into the heat collection shroud through the air inlet shroud, the blower pipe, and two air supply pipes, cooling multiple heat dissipation fins. Meanwhile, the hot air inside the power cabinet transfers heat to the multiple heat dissipation fins through the heat absorption plate, thus achieving cooling of the power cabinet and preventing damage to internal components due to excessive temperature.
