Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Of course, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on The claims in the present invention, except for the embodiments but within the scope of the claims, also belong to the protection scope of the present invention.

[0015] as attached figure 1 , figure 2 , image 3 Figure 4 , Figure 5 As shown, the main structure of the present invention is basically two parts: plate 1 and fin 2 (the main water inlet or water outlet is welded with pipe fittings or screw joints), and they are all stamped and formed. The plate is provided with water tanks and ribs. The two plates are superimposed in reverse to form a waterway; a fin is implanted between the stacked plate groups; holes are arranged on the plates...

Abstract

The invention discloses a plate-fin heat exchanger which is formed by brazing multiple plate sheet sets and multiple fins at intervals in an implanting mode. Each plate sheet set comprises two identical plate sheets, water channels and ribs are arranged on the plate sheets, every two plate sheets are overlapped inversely to form a water path, openings are formed in the plate sheets in a central axis symmetry mode, holes are correspondingly formed in the fins, after the fins are implanted into the plate sheet sets, forming is carried out through one-time brazing, and the main flow path of the plate sheet sets is formed by overlapping the openings formed in the plate sheets in the central axis symmetry mode and the corresponding holes of the fins. The plate-fin heat exchanger is simple in processing and manufacturing, only two kinds of accessories (the plate sheets and the fins) need to be stamped, one-time forming can be achieved through overlapping brazing, the plate sheets form water flow ways, components are saved, heat loads can be increased, the heat effect is improved, the problems of the air stagnation phenomenon of transverse small space above the water paths, water resistance and air resistance are effectively solved through the hole punching structure and the hole forming mode of the plate sheets, and heat exchange efficiency is high.

Description

technical field [0001] The invention relates to a heat exchanger, more specifically, a plate-fin heat exchanger used for gas boilers, gas wall-hung boilers, gas water heaters and the like. Background technique [0002] Existing products of the same type are usually alternately laminated with plates and fins, and the fins are sealed with multiple heads around them. The gaps in the fins form air passages, and there are main water inlet pipes (and water inlets) that must be welded separately and The main water outlet pipe (mouth), its water channel is usually a tube body or a flat tube; the plates in it are mainly used to separate two adjacent fins to form a water channel or an air channel, and have a certain strengthening effect. There are many parts, the product volume is large (occupying space), the production and maintenance costs are high, the process is complicated, the thermal efficiency is low, and it cannot be formed in one time. Contents of the invention [0003] T...
