Electrical component mounting apparatus driven and powered by solar energy and provided with good heat dissipation performance

Abstract

An electrical component mounting apparatus driven and powered by solar energy and provided with a good heat dissipation performance is disclosed. The mounting apparatus comprises a cross beam (13) for fixing electrical components (131), and a cooling assembly connected with the end part of the cross beam (13); the cooling assembly comprises a shell frame (7) fixed in the end part of the cross beam (13) and a fan apparatus (2) capable of rotating relative to the shell frame (7); the fan apparatus (2) comprises a mounting shell (17) with an airflow flowing opening (171), a fan motor (221) mounted in the mounting shell and fan blades (22) in power connection with the fan motor (221); a plurality of heat dissipation fins (220) for absorbing and dissipating the heat generated in the running process of the fan motor (221) are transversely arranged on the surface of the shell of the fan motor (221); and a small-sized exhaust fan (219) for accelerating the dissipation of the heat absorbed by the multiple heat dissipation fins (220) for improving the heat dissipation efficiency is fixed on the heat dissipation fins (220), so as to prevent the fan motor (221) from being burnt caused by the overhigh temperature in a long-term operation.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power electric component installation device with good heat dissipation performance and powered by solar power. Background technique [0002] In the field of power and electricity, some electrical components such as relay switches, overload protectors, circuit breakers and other devices often generate heat during use. This heating phenomenon will not directly affect the safety of electricity use and equipment installation in a short period of time, but the long-term heating and overheating phenomenon will have an adverse effect on the mechanical structure of the device's shell, bracket, etc., and cause the mechanical strength of these structures to fail. , resulting in serious accidents. [0003] In cooling devices for these devices, fans uniformly installed on the box body are often used to centrally dissipate heat from the internal space containing these devices. This plays a ...

Problems solved by technology

However, it is still difficult to play a targeted role in the cooling and heat dissipation of the main heat-generating devices that are significantly higher than other devices during use.

Moreover, some centralized heat dissipation equipment is likely to cause difficulties in the maintenance of such main power devices, which may interfere with the positioning and installation of such power components during operation, and may also cause interference to the operation of such power devices
