Example Embodiment

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0015] See Figure 1-3 , A convection heat-dissipating power distribution cabinet, including a base 1 and a cabinet 2. The cabinet 2 is installed on the base 1. A cabinet 2 and a cover 3 are arranged above the base 1. The cross-sectional area of ​​the cover 3 is larger than that of the cabinet. The cross-sectional area of ​​the body 2, the cover plate 3 is set above the cabinet body 2. The cover plate 3 is used to protect the cabinet bod...

Abstract

The invention discloses a convection heat-radiating power distribution cabinet. The convention heat-radiating power distribution cabinet comprises a base and a cabinet body, wherein the cabinet body and a cover plate are arranged above the base, a side plate is provided with a ventilation hole and an air inlet, the air inlet is located above the air inlet, the side plate is also provided with a baffle plate and an air inlet air duct, and the air inlet air duct is connected with the air inlet. According to the convection heat-radiating power distribution cabinet, the low-temperature air outsidethe power distribution cabinet enters the power distribution cabinet from the air inlet to cool electrical equipment, the baffle plate and the air inlet air duct can respectively prevent rainy waterfrom entering the power distribution cabinet from the air inlet so as to ensure the dryness in the power distribution cabinet, an opening of the air inlet air duct downwardly inclines for 30 degrees,cold air cools the electrical equipment in all directions from bottom to top, the electrical equipment can be uniformly cooled, an exhaust fan is used for exhausting the air, hot air in the power distribution cabinet is discharged to be above the exhaust fan, the position of the ventilation hole is higher than the position of the exhaust fan, and the hot air is dissipated into the atmosphere by virtue of the ventilation hole, so that the exhaust fan accelerates the flow speed of the air and improves the heat radiation efficiency.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a convection heat dissipation type power distribution cabinet. Background technique [0002] The power distribution cabinet is an electrical equipment that assembles various electrical components in a box. It is generally installed outdoors. Due to the influence of the external ambient temperature and the heating of its own components, the switch in the distribution box will frequently trip in the summer high temperature season. It affects the reliability of power supply. In order to cool down the power distribution cabinet, in the prior art, there are generally cooling holes on the cabinet body of the power distribution cabinet to achieve the purpose of cooling. However, if the cooling holes are too small, the heat dissipation requirements cannot be met, and the heat dissipation efficiency Low, if the area of ​​the heat dissipation holes is increased, the hea...
