Abstract

The radiator of the utility model takes external ribbed aluminium tubes via extrusion molding as a main body. The cross-section of an inner wall forms a rectangular shape with a small round angle, and an outer wall is provided with a plurality of longitudinal ribs connected with the wall of the tubes as an entity. An upper port and a lower port are respectively welded with cast molding external ribbed aluminium end covers having two side walls with screw holes. The utility model has the advantages of uniform wall thickness, high density, high pressure bearing capability, favorable heat transfer performance, large heat dispersion area, strong corrosion resistance, smooth and beautiful appearance, light structure and simple processing.

Description

Radiator with external-assistant aluminium conduit

The design is in the comprehensive improvement aspect material and the version to popular radiator.

Be popular in the radiator of several main types of society at present, its chief and deficiency are respectively arranged: (1) sheet metal welded radiator, though wall is thin, production process needs through operations such as blanking, punching press, welding, assembling, japannings, and outside wall surface is difficult to make more radiated rib; (2) fin-tube radiator, though constitute bigger area of dissipation with more fin, poling is thin, with pipe in the hot fluid heat exchange area that flows less, and poling is not one with the string sheet, the thermal resistance that the structure interval existence is bigger; (3) cast iron external fin formula radiator, though have bigger water cavity and more and water cavity wall are the outer fin of one, wall thickness, heaviness, heat transfer coefficient is less.

The design's radiator has been drawn the advantage of above-mentioned radiator and has been given up its deficiency, and then form following feature: (1) with the external fin formula thin-walled aluminium pipe 1 of the extrusion modling main body as radiator, and the cross section of its inwall is that to be shaped on some and tube wall on the rectangle that has little fillet, the outer wall be the longitudinal fin J of one ₁, weld respectively with the external fin formula thin-wall aluminum alloy end cap 2 of die cast and 3 and constitute water cavity K at 1 upper and lower port place; (2) outside wall surface of the flared end of upper end cover 2 and 1 internal face match and are welded in 1 upper port place; 2 the E of end socket portion is vertical semicircle tubulose, removes the part of welding mutually with 1 upper port on 2 the outside wall surface, to be shaped on some axis with E perpendicular and become the thin fin J of similar figures with 2 wall ₂Respectively be shaped on round boss G and the tapped through hole H concentric with this boss on 2 the two side, the H hole can match with external pipe fitting; (3) structure of bottom end cover 3 and all identical with 2 with the form of joining at 1 lower port place; (4) the 1st, by the intercepting section (the type pipe of making on the extruded threads generally is longer than six meters) of the external fin formula thin-walled aluminium pipe of the design's feature extrusion modling, 2 and 3 is through the one-time formed external fin formula of die casting thin-wall aluminum alloy structural member.

Produce heat sink assembly by extruding and die casting advanced technologies, not only the production efficiency height and also make that the design's radiator has that thin-walled is even, close withstand voltage, the good heat-transfer of matter, area of dissipation is big, corrosion resistance is strong, advantages such as gloss is attractive in appearance, and because of the light and handy manufacture craft of structure simple.If need the height of change radiator, then only be the intercepted length of change 1 on extruded threads, thereby as long as one pair of mold and one pair of crowded mould can be produced the radiator of differing heights.

When using the design's radiator, a H hole of upper end cover 2 is connect the hot fluid pipeline, revolve with the plug with small-sized exhaust steam valve in another H hole; A H hole of bottom end cover 3 is taken back waterpipe, and revolve with plug in another H hole.Also can connect and the parallel form of formation the design radiator with the adjacent H hole of pipe fitting with several the design's radiators side by side.

Fig. 1 is the structural representation of the design's radiator, Fig. 2 be part 1 cross-sectional view, be the A-A profile of Fig. 1, Fig. 3 be part 2 sectional view, be the B-B cutaway view of Fig. 1, Fig. 4 is the side view of the design's radiator.Among the figure:

1: outer rib aluminium shaped tube

Claims

The outer rib aluminium shaped tube radiator, feature is as follows:

1, with the external fin formula thin-walled aluminium pipe 1 of extrusion modling as main body, the cross section of 1 inwall is that to be shaped on some and tube wall on the rectangle that has little fillet, the outer wall be the longitudinal fin J of one ₁, weld respectively with the external fin formula Thin-walled Aluminum end cap 2 of die cast and 3 and constitute water cavity K at 1 upper and lower port place;

2, the outside wall surface of the flared end of upper end cover 2 and 1 internal face match and are welded in 1 upper port place, 2 the E of end socket portion is vertical semicircle tubulose, removes the part of welding mutually with 1 upper port on 2 the outside wall surface, to be shaped on some axis with E perpendicular and become the thin fin J of similar figures with 2 wall ₂, respectively being shaped on round boss G and the tapped through hole H concentric on 2 the two side with this boss, the H hole can match with external pipe fitting;

3, the structure of bottom end cover 3 and all identical with 2 with the form of joining at 1 lower port place;

4, the 1st, by the intercepting section of the external fin formula thin-walled aluminium pipe of the design's feature extrusion modling, 2 and (or) the 3rd, by the one-time formed external fin formula of die casting Thin-walled Aluminum structural member.
