Control circuit board heat dissipation mounting box with conveniently disassembled filter screen plate

Abstract

The invention discloses a control circuit board heat dissipation mounting box with a conveniently disassembled filter screen plate. The control circuit board heat dissipation mounting box comprises amain base plate and a mounting box body, wherein the top surface of the main base plate is fixedly connected with the mounting box body through bolts; the middle part of the mounting box body is provided with a middle mounting plate; the front wall surface and the rear wall surface of the middle mounting plate are fixedly connected onto the front wall plate and the rear wall plate of the mountingbox body through bolts; vertical plates are fixedly arranged on the left and right sides of the top surface of the middle mounting plate; a plurality of circulating ventilation fans are fixedly arranged on the outer side walls of the two vertical plates respectively; air outlets of the circulating ventilation fans face ventilation holes in the vertical plates; and an upper circulating ventilationfan is fixedly arranged at the bottom of the middle part of the top plate of the mounting box body. According to the control circuit board heat dissipation mounting box, the middle mounting plate is mounted inside the mounting box body, the circulating ventilation fans and the upper circulating ventilation fan are arranged on the middle mounting plate so as to realize rapid air inlet and air outlet inside the mounting box body, the heat dissipation effect is good, the efficiency is high, simultaneously, the control circuit board heat dissipation mounting box is provided with the filter screenplate capable of preventing dust and sundries, and the filter screen plate is convenient to disassemble, change and maintain.

Description

Technical field: [0001] The invention relates to the technical field of radio electronic equipment, and more specifically relates to a control circuit board heat dissipation installation box with a filter screen board that can be easily disassembled. Background technique: [0002] Existing controllers, control circuit boards, etc. are generally fixed in the installation box, and the existing electric control installation box generally only has heat dissipation through holes, and there are no other heat dissipation components. At most, the chips are installed on the heat dissipation board. Comes with cooling fan, its effect is limited. [0003] At the same time, there is no dust-proof device such as a filter screen in the existing installation box, so that dust or other sundries can easily enter the installation box through the heat dissipation through holes of the installation box, affecting the use. Invention content: [0004] The object of the present invention is to ad...
