Problems solved by technology

[0005] The fan of the above-mentioned patent is not installed on the machine core support, but is installed on the chassis; the first air duct communicates with the heat dissipation channel formed by the fan through the air inlet opened on the machine core support, and is limited by the air inlet It will directly affect the air volume in the first air duct and thus affect the cooling effect of the movement
If the heat dissipation object of the first air duct is larger than the heat dissipated by the core, the heat dissipated by the first air duct is far from achieving the cooling effect

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] refer to figure 1 , is a movement support disclosed by the present invention, including an L-shaped base 1, a circular air inlet 2 is opened on the vertical plate of the L-shaped base 1, and a fan is installed on the air inlet 2 in this embodiment. A first mounting plate 6 is vertically installed on the horizontal plate of the L-shaped base 1 below the air inlet 2 , and one end of the first mounting plate 6 is vertically connected to the vertical plate of the L-shaped base 1 . The first mounting plate 6 away from the end connected to the horizontal plate of the L-shaped base 1 is vertically connected to one end of the first supporting plate 7 , and the first supporting plate 7 is arranged parallel to the horizontal plate of the L-shaped base 1 .

[0041] refer to figure 2 , A first inner cavity is formed between the base 1 , the first mounting plate...

Abstract

The present invention relates to the technical field of brackets, and relates to a movement bracket, including a base, an air inlet is opened on the base, a drainage plate is installed on the base on the side of the air inlet, and a drainage plate is installed on the base on the side of the drainage plate. A first heat dissipation flow passage communicated with the air inlet is formed, and a second heat dissipation passage communicated with the air inlet is formed on the base on the other side of the flow guide plate. Heat dissipation runner connection setting. In the present invention, the first heat dissipation flow channel and the second heat dissipation flow channel are directly connected to the air inlet, and the drainage plate only drains the air intake from the air inlet, which not only reduces the unsatisfactory local heat dissipation effect, but also ensures that the air intake from the air inlet The air volume can fully dissipate heat.

Description

technical field [0001] The invention relates to the technical field of brackets, in particular to a movement bracket. Background technique [0002] The inverter welding machine rectifies and filters the three-phase or single-phase 50Hz power frequency AC to obtain a smoother DC. The inverter circuit composed of IGBT or field effect tube converts the DC into 15-100kHz AC. After the main transformer is stepped down, it is rectified and filtered again to obtain a stable DC output welding current (or re-inverted to output AC with the required frequency). The control circuit of the inverter welding and cutting equipment is composed of a given circuit and a drive circuit. By processing the feedback of voltage and current signals, the cycle control of the whole machine is realized. The control technology of pulse width modulation (PWM) is used as the core to obtain a fast pulse. Widely modulated constant current characteristics and excellent welding and cutting process effects. ...
