Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, and in particular to a multi-layer drawer-type electrical cabinet with good heat dissipation. Background Art

[0002] A drawer-type electrical cabinet is a type of electrical cabinet. It is a closed shell made of steel plates. The electrical components of the incoming and outgoing line circuits are installed in a removable drawer, forming a functional unit that can complete a certain type of power supply task. The functional unit is separated from the busbar or cable by a grounded metal plate or a functional board made of plastic, forming three areas: the busbar, the functional unit, and the cable. There are also isolation measures between each functional unit. The drawer-type electrical cabinet has high reliability, safety, and interchangeability. It is a relatively advanced electrical cabinet. Most of the electrical cabinets currently produced are drawer-type electrical cabinets. There are still some problems with the existing drawer-type electrical cabinets during use:

[0003] 1. Poor heat dissipation. The internal components of the existing drawer-type electrical cabinets generate a lot of heat. If the internal heat cannot be dissipated well, the internal electrical components of the electrical cabinet may burn out. In severe cases, a fire may occur due to the increase in temperature, resulting in a safety accident.

[0004] 2. Poor dust and moisture proofing effects. In the process of using the existing drawer-type electrical cabinets, in order to improve the rapid cooling of the components inside the electrical cabinet, most of them use flowing cold air to blow directly into the electrical cabinet, thereby achieving the cooling treatment inside the electrical cabinet. However, with long-term use, the air constantly blown in from the outside will be accompanied by a large amount of dust, and the dust will stick to the electronic components and break the static balance, thereby greatly reducing the service life of the electronic components.
