Description

Technical Field

[0001] The utility model belongs to the technical field of converter cabinets, and in particular relates to a novel converter cabinet. Background Art

[0002] Converters are electrical devices that change the voltage, frequency, number of phases, and other electrical quantities or characteristics of a power system. With the increasing development of society and the economy, total electricity consumption and frequency have increased significantly, including for industrial, residential, and special applications. This has led to greater demand and higher requirements for converter cabinets. Conventional converter cabinets are primarily used to safely store various electrical equipment and ensure their functional connectivity and operation.

[0003] At present, the existing converter cabinet generates a lot of heat due to the operation of the internal electrical components. The traditional ventilation and heat dissipation through fans can achieve good heat dissipation effects. However, external dust can easily enter the equipment through the ventilation holes, causing dust to accumulate inside the equipment. Long-term accumulation can easily affect the self-heating of the electrical components inside the equipment, causing the electrical components to overload and thus reduce the service life of the electrical components. For this reason, we propose a new converter cabinet. Utility Model Content

[0004] The purpose of the present invention is to provide a new converter cabinet to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new type of converter cabinet, comprising a cabinet body, a heat dissipation trough and a cooling fin, a heat dissipation trough being provided inside the shell of the cabinet body, and heat conduction plates being provided at multiple positions inside the heat dissipation trough, the heat conduction plate being fixedly embedded in the inner wall of the shell of the cabinet body, one side of the heat conduction plate extending to the interior of the cabinet body, and the other side of the heat conduction plate being placed inside the heat dissipation trough, a cooling fin being fixedly installed on the surface of one side of the heat conduction plate placed inside the heat dissipation trough through thermal silicone grease, the heat absorbing end of the cooling fin being fixedly connected to the heat conduction plate, and the heat releasing end of the cooling fin being fixedly connected to the cooling fin through thermal silicone grease, the cooling fin being placed inside the heat dissipation trough, a layer plate being provided inside the cabinet body, and heat conduction plates being also provided on the top and bottom surfaces of the layer plate.

[0006] Preferably, an air inlet is provided at the bottom end of one side of the cabinet, an exhaust port is provided at the top end of one side of the cabinet away from the air inlet, and fans are fixedly installed on the inner sides of the air inlet and the exhaust port.

[0007] Preferably, heat conducting rods are provided around the outside of the refrigeration fins, and two sides of the heat conducting rods are in close contact with the heat conducting plate and the heat dissipating fins respectively.

[0008] Preferably, a heat insulating layer is filled between the heat conducting plate and the heat dissipating fins, and the heat insulating layer wraps around the periphery of the cooling plate and the heat conducting rod but does not affect the contact between the two and the heat conducting plate and the heat dissipating fins.

[0009] Preferably, dustproof nets are provided on the peripheries of the air inlet and the exhaust port, and the dustproof nets are fixedly installed on the outer sides of the air inlet and the exhaust port by gluing.

[0010] Preferably, a cabinet door is provided on an outer side of the cabinet body, and one side of the cabinet door is movably connected to the cabinet body through a hinge.

[0011] Preferably, an observation window is provided in the middle of the cabinet door, and the inner side of the observation window is inlaid with tempered glass.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. A heat dissipation slot is opened inside the cabinet shell, and a heat conducting plate is embedded inside the heat dissipation slot near the inner wall of the cabinet. The heat conducting plate absorbs the heat generated by the operation of the equipment inside the cabinet, and then the heat is transferred to the heat dissipation fins by the cooling plate. The heat dissipation fins diffuse the heat into the heat dissipation slot. Finally, the fans in the air inlet and exhaust ports ventilate and dissipate the heat inside the heat dissipation slot, thereby achieving the purpose of heat dissipation by heat transfer, while ensuring efficient heat dissipation and preventing the entry of external dust.

[0014] 2. By setting heat conducting rods around the cooling plate, the contact area of ​​the cooling plate is increased, thereby improving the efficiency of heat transfer and indirectly achieving the purpose of improving the heat dissipation efficiency. By wrapping the outer periphery of the cooling plate with a heat insulation layer, the heat absorbing end of the cooling plate is prevented from being affected by the temperature inside the heat sink, thereby ensuring the stable operation of the cooling plate.
