Description

Technical Field

[0001] The utility model belongs to the technical field of electrical cabinets, and in particular relates to a high and low voltage electrical drawer cabinet. Background Art

[0002] High and low voltage electrical drawer cabinet is a modular design of power distribution equipment with a drawer structure. It can easily replace and upgrade the internal switch components and protection components, which is convenient for maintenance and management. The main function of the drawer type high and low voltage switch cabinet is to distribute electrical energy to various load parts and to provide power-off protection when abnormal conditions such as short circuit and overload occur in the circuit. Its main components include circuit breakers, contactors, intermediate relays and buttons. Among them, the circuit breaker is used to distribute power and protect components such as power lines; the contactor consists of an electromagnetic mechanism and a contact system, which is used to switch the main circuit and the control circuit; the intermediate relay is used to convert the input signal into multiple output signals or amplify the signal; the button is used to control the on and off of the circuit.

[0003] There may be many reasons why the heat dissipation of high and low voltage electrical drawer cabinets is poor. Here are some possible reasons:

[0004] Design issues: During the design of the drawer cabinet, the heat dissipation requirements may not be fully considered. For example, the location and size of the radiator and the density of the heat sink may not be set properly, resulting in poor heat dissipation. In addition, if the heat dissipation holes and heat dissipation slots are not designed properly or the number is insufficient, it will also affect air circulation, thereby affecting the heat dissipation effect.

[0005] Excessive load: When the load inside the drawer cabinet is too large, the heat generated by the electrical components will increase significantly. If the cooling system cannot dissipate this heat in a timely and effective manner, the temperature inside the drawer cabinet will be too high.

[0006] Poor ventilation: Ventilation is a key factor in heat dissipation. If the vents of the drawer cabinet are blocked or the ventilation design is unreasonable, it will affect air circulation, resulting in poor heat dissipation. In addition, if the installation environment of the drawer cabinet itself is poorly ventilated, it will also have a negative impact on the heat dissipation effect.

[0007] Airflow dead corners: The existing heat dissipation structure causes poor airflow, which reduces the heat exchange efficiency. After the airflow is discharged, it is very easy to stir up dust, causing static electricity to attach dust. Utility Model Content
