AI Technical Summary

Technical Problem

In the existing technology, thin-walled corrugated pipes are prone to cracking and leaking water during the cooling process of reflow ovens, and the corrosiveness of water causes equipment damage, affects the quality of welds and causes economic losses. In addition, the existing heating devices have poor heating and heat preservation effects.

Method used

It adopts an integrated molded cooling coil, combined with a spiral design and insulation unit. Heat exchange is carried out through the spiral cooling coil, and the cooling coil is connected by clamps and flanges to achieve convenient installation and maintenance. The insulation board is set to isolate the influence of external temperature.

Benefits of technology

It improves cooling efficiency, prevents cooling coils from cracking due to stress concentration, achieves good temperature control and insulation, and simplifies the installation and maintenance process.

Abstract

This utility model relates to a heating device based on an integrally molded cooling coil, including a furnace chamber and a furnace chamber sealing plate installed on the furnace chamber. The device also includes a heating unit, a cooling coil, a first connecting pipe, a second connecting pipe, a water outlet connector, a water inlet connector, a heat insulation unit, and a check valve. The heat insulation unit is installed inside the second connecting pipe. The cooling coil passes through the first connecting pipe and the heat insulation unit in sequence and is connected to the water outlet connector and the water inlet connector respectively. The check valve is connected to the water outlet connector. The first connecting pipe is installed on the heating unit and the cooling coil is located inside the heating unit. The second connecting pipe is installed on the furnace chamber sealing plate of the furnace chamber. The cooling coil of this utility model is integrally molded. In traditional manufacturing processes, residual stress will be generated. Under the pressure of cooling water and the action of residual stress, cracking will occur, causing water leakage. The structure avoids stress concentration caused by welding points.
