Soldering furnace waste heat treatment equipment based on convective heat exchange

Abstract

The invention discloses soldering furnace waste heat treatment equipment based on convective heat exchange. The equipment structurally comprises a closing cylinder, a bottom support, a dustproof net, a reinforcing plate, a liquid feeding pipe, a liquid return pipe, a hand valve, an oil pump, an oil guide bin, a bottom edge, a top cover, a heat exchange ring pipe, a liquid inlet connecting pipe, a liquid guide connecting pipe, heat conduction oil, heat dissipation holes, a liquid inlet pipe, a heat conveying mechanism, a heat conveying ring pipe, a heat storage mechanism, a heat detection probe and a heat insulation mechanism. The equipment has the following beneficial effects that after a heat exchange guide pipe makes contact with heat flow, heat is absorbed and exchanged through the heat conduction oil, heat is guided through the heat conveying mechanism after the heat conveying ring pipe absorbs the heat, the heat is dissipated after the heat is stored through the heat storage mechanism, preheating heat is provided for plates, the welding heat flow and waste heat can be effectively treated and recycled, the heat energy loss during operation is reduced, the heat utilization rate is increased, and the energy-saving effect is improved.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a convective heat transfer based soldering furnace waste heat treatment equipment. Background technique [0002] The solder furnace is mainly used in wave soldering or manual soldering to melt lead-free solder wire for soldering of circuit boards, printed circuit board industry and copper clad laminate industry. The welding process is usually performed by wave soldering or reflow soldering; [0003] When the existing soldering furnace is in use, whether it is wave soldering or reflow soldering, it is often necessary to preheat the board during soldering. The traditional methods are hot air convection, electric heating plate convection, Electric heating rod convection and infrared heating, etc., and when welding is often accompanied by more heat flow diffusion on the welding surface, the lost heat flow is often accompanied by higher temperature, which is prone to produce more was...

Problems solved by technology

[0003]When the existing soldering furnace is in use, whether it is wave soldering or reflow soldering, it is often necessary to pre-heat the board during soldering. Heat treatment, the traditional methods are hot air convection, electric heating plate convection, electric heating rod convection and infrared heating, etc., and when welding is often accompanied by more heat flow diffusion on the welding surface, the lost heat flow is often accompanied by higher temperature, it is easy to generate more waste heat, which makes it difficult to collect the waste heat in the welding process when the solder furnace is running, which is easy to cause waste of heat energy. and energy-consuming equipment
