Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in fig. 1 and 2, a high-efficiency sea fresh water heat exchanger core comprises tube plates 1 arranged at two sides, and a plurality of heat exchange core tubes 2 are uniformly distributed between the tube plates 1; the tube plate 1 is provided with a tube hole; in the tube hole was penetrated to 2 both ends of heat transfer core pipe, 2 tip of heat transfer core pipe were formed with expansion mouth 3 through the extrusion in the port department, made heat transfer core pipe 2 fixed with tube sheet 1 through expansion mouth 3, and the specially-made tapered column of accessible extrudees the tube hole wholly during the extrusion, need not the welding, and production and processing efficiency is high on the one hand, and on the other hand avoids the smog of welding production, and the processing mode is environmental protection more.
After the expansion opening 3 is formed, a tin soldering layer 4 is infiltrated between the periphery of the expansion opening 3 and the tube plate 1 in an infiltration mode, the tin soldering layer 4 enables the tube plate 1 and the heat exchange core tube 2 to be sealed, leakage is avoided, redundant tin inside the expansion opening 3 is removed through a tin cleaning machine after infiltration, the redundant tin outside the expansion opening 3 is removed, the tin soldering layer 4 is enabled to be flush with the surface of the expansion opening 3, and appearance quality is ensured.
In this embodiment, heat exchange core pipe 2 adopts the copper pipe, and copper pipe heat exchange efficiency is high, and the equipartition has polylith baffling board 5 on heat exchange core pipe 2 simultaneously, utilizes baffling board 5 to improve the inside shell side of inside heat exchanger, improves heat exchange efficiency.
A check ring 6 is integrally formed on the outer ring of the tube plate 1, and two annular grooves are processed on the outer side of the check ring 6; the annular groove is sleeved with a sealing ring 7, and the tube plate 1 and the heat exchanger are sealed by arranging the sealing ring 7.
The present invention is not limited to the embodiments described above, and those skilled in the art may make modifications or changes within the scope of the disclosure without departing from the spirit of the present invention, so that the scope of the present invention is defined by the appended claims.
