Problems solved by technology

In order to closely match the steel pipe and the aluminum fin, it is necessary to insert the steel pipe into the longitudinal through hole of the aluminum fin first, and then use the pipe expansion process. Due to the size error of the steel pipe, the aluminum fin is sometimes cracked and scrapped.
In order to avoid such a situation, the usual practice is to improve the dimensional accuracy of the longitudinal through holes of the steel pipe and the aluminum fin, which increases the cost and affects the market competitiveness of the product

Embodiment Construction

[0014] As shown in Figures 1 and 3, the improved steel-aluminum composite column fin radiator includes a column fin radiator 1 and an upper header pipe 2 and a lower header pipe 3 communicating with it, the column fin radiator 1 It includes an aluminum cylinder 11, an aluminum fin 12 is provided on the outer peripheral surface of the aluminum cylinder 11, and a steel pipe 4 closely matched with it is arranged inside the aluminum cylinder 11, and the two sides of the steel pipe 4 The ends are respectively welded with the upper header pipe 2 and the lower header pipe 3. The aluminum cylinder 11 is provided with at least one longitudinal opening 5, and this embodiment is provided with two opposite longitudinal openings 5. The aluminum cylinder 11 A clamping device 6 is provided at the longitudinal opening 5; through the clamping device 6, the aluminum cylinder 11 can be elastically deformed to a certain extent, so as to be tightly hugged on the steel pipe 4. In this way, not only ...

Abstract

The improved finned heat sink with composite steel-aluminum tubes includes heat radiating finned tubes, and upper collecting box and lower connecting box connected to the heat radiating finned tubes. The heat radiating finned tube includes one aluminum tube, aluminum fins around the aluminum tube and one steel tube fitted closely inside the aluminum tube. The steel tubes are welded to the upper collecting box and the lower connecting box, and the aluminum tube has at least one longitudinal slot for enclasping the steel tube tightly through elastic deformation. The present invention has simple steel tube-aluminum tube combining process and lowered production cost of the finned heat sink with composite steel-aluminum tubes.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a column-fin radiator composed of steel pipes and aluminum fins. Background technique [0002] A known steel-aluminum composite column fin radiator includes a column fin radiator and upper and lower header pipes communicating with it, the column fin radiator includes a cylindrical aluminum fin with a longitudinal through hole inside, In the longitudinal through hole of the aluminum fin, there is a steel pipe tightly matched with it, and the two ends of the steel pipe are respectively welded to the upper and lower header pipes. Due to the use of cylindrical aluminum fins, the heat dissipation area of ​​the radiator is increased and the heat dissipation efficiency is high; at the same time, the longitudinal through holes of the aluminum fins are equipped with steel pipes that are closely matched with them, and the water flows through the steel pipes to avoid contact with the alum...
