Embodiment Construction

[0018] like Figure 1-3 As shown, the anti-corrosion light-weight and high-efficiency finned heat exchanger includes several laminated fins 1, and several inner tubes 2 are installed on the fins 1, and there is a The slot 3 is used to connect two adjacent fins 1 through the slot 3 .

[0019] In order to ensure the service life of the heat exchanger in the corrosive environment and improve the corrosion resistance, ceramicization and sealing treatment are performed on the surface of the heat exchanger fin 1 to form a strong and dense anti-corrosion film to prevent acid and alkali corrosion and oxidation.

[0020] Due to the adoption of ceramic treatment technology, conditions are created for the use of light metals with poor corrosion resistance. The invention makes it possible to manufacture anti-corrosion heat exchangers using materials such as aluminum and aluminum alloys, magnesium and magnesium alloys, titanium and titanium alloys. .

[0021] The invention adopts a new d...

Abstract

The invention relates to an anti-corrosion light high-efficiency finned type heat exchanger, which comprises a plurality of laminated fins. A plurality of inner tubes are arranged on the fins; an insert grooves are arranged at joints of the fins and the inner tubes; and two adjacent fins are connected through the insert groove. In order to ensure the service life of the heat exchanger in a corrosive environment and improve corrosion resistance, the surface of each fin of the heat exchanger is subjected to ceramic and seal treatment to form a strong and compact anti-corrosion film, so that acid and alkali corrosion and oxidation are prevented. By the ceramic treatment technology, conditions are created for using light metal with low corrosion resistance. The anti-corrosion heat exchanger made of materials such as aluminum and an aluminum alloy, magnesium and a magnesium alloy, titanium and a titanium alloy and the like is realized. The close fit among the fins, and the close fit among the fins and the inner tubes are realized, a gap does not exist and a soldering process can be saved. Innovative designs are adopted, so the product has the advantages of high cost performance, good economic benefit, energy conservation and emission reduction, low manufacturing cost and easy marketing.

Description

technical field [0001] The present invention relates to a heat exchanger. Background technique [0002] The structure of similar products adopts the butt joint method. After the fins are butt joint, in order to ensure that there is no gap in the connection, a welding process must be used for welding connection. In this way, the quality of the equipment is affected by the quality of the welding, and after welding, it is easy to generate internal stress, which makes the equipment prone to problems such as cracks. Contents of the invention [0003] The object of the present invention is to provide an anti-corrosion, lightweight and high-efficiency finned heat exchanger, which solves the problem that the equipment needs to be welded and is restricted by the welding process. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] Anti-corrosion, lightweight and high-efficiency finned heat exchanger, including several lam...
