Description

Technical Field

[0001] The utility model relates to a monitoring device, in particular to a novel water flow monitoring device applied to a reflow furnace, belonging to the technical field of water cooling systems of reflow furnaces. Background Art

[0002] The reflow oven water cooling system is a key heat dissipation technology in PCB manufacturing. It utilizes water's excellent thermal conductivity to effectively absorb and dissipate the substantial heat generated within the reflow oven through a circulating flow, ensuring stable temperatures during the soldering process, preventing soldering defects, and improving product quality. This system not only offers high heat dissipation efficiency but also operates quietly and with high adaptability, allowing for customization and optimization based on diverse soldering requirements.

[0003] The soldering furnace's water cooling system, as the core component of equipment cooling, is directly related to the stability and quality of the product process. During the operation of the water cooling system, any water flow anomalies, such as insufficient or fluctuating flow, can cause the soldering furnace's temperature control to fail, significantly increasing product scrap rates and posing quality risks. The current industry-wide strategy is to monitor the temperature range of the cooling zone and manage it by setting upper and lower temperature limits. However, this approach ignores the critical parameter of real-time flow rate, failing to immediately reflect the cooling effect or provide real-time feedback for cooling effect adjustments. Therefore, a new water flow monitoring device for reflow ovens is proposed. Utility Model Content
