CN2101842U - Radiator with external rib al type pipe - Google Patents

Abstract

The radiator of the utility model takes an external fin aluminium pipe via extrusion molding as a main body. Two ends of the radiator are matched with connecting pipes, and the connecting pipes are provided with threads or flanges for connection. The utility model has the advantages of simple structure, convenient production, low cost, large heat dispersion area, high metal fever intensity, favorable air tightness, strong corrosion resistance, good mechanical property, smooth and beautiful surface, etc. The radiator can be used as a heating appliance for vehicles, ships, high-rise buildings, etc.

Description

Radiator with external rib Al type pipe

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

With series connection and the tubular radiator that combines in parallel, be popular in vehicle, boats and ships, and a considerable amount of civil buildings in.Constitute the steel pipe of this class radiator, be the carrier pipe of fluid, be radiating tube (for example vertical steam heating pipe under the seat of passenger car railway carriage or compartment) again, its advantage is simple structure, convenient by dress, air-tightness is better; But, and can not satisfy the needs of some circumstances heating owing to the surface area release less, heat of body is restricted; If enlarge area of dissipation by quantity and the length that increases pipe simply, then not only increase the consumption of material, and be subjected to the restriction in space.

By " thermal conduction study " basic theories as can be known, the heat transfer of metal wall both sides differential temperature fluid, should strengthen the less side of exothermic coefficient (as seeing as described in " thermal conduction study basis " chapter 6 the 5th joint that the inscription on pottery select edited) emphatically, and the thermal conductivity of metal and corrosion resistance also are the key factors that influences the radiator result of use.The design's radiator adopts the main body 1 of the outer rib aluminium shaped tube (promptly be shaped on some with tube wall be the longitudinal fin J of one) of extrusion modling as radiator on the outside wall surface of type pipe, in the welding connecting tube 2 of the two-port place of main body 1, in connecting tube 2, can be shaped on screw thread or the flange 3 of making to connect usefulness, can be shaped on nut through hole H on the flange 3.This outer rib aluminium shaped tube radiator is configured in water, the steam heating system with series connection and parallel form.

Though the design's radiator simple structure has following comprehensive advantage: the outer rib aluminium shaped tube of producing on (1) extruded threads reaches several meters, can be random length according to the designing requirement scale, the extrusion process maturation, production efficiency is higher, and profile wall is evenly thin, thereby has reduced the cost of radiator.(2) though the outer rib aluminium shaped tube wall is thin, air-tightness is good; Its some outer fins are fin, are the reinforced sheets of type pipe again, thereby can make radiator water pressure resistance intensity reach 15kg/cm ², and competent vehicle, boats and ships, with skyscraper etc. to water, the higher specification requirement of steam heating system.(3) outer rib aluminium shaped tube proportion is little, thermal conductivity is high, and the surface radiating area is big; If equal heat dissipation capacity, its body weight only is equivalent to some/one of iron and steel radiator, thus can alleviate vehicle, boats and ships, skyscraper from heavy load.(4) surface of outer rib aluminium shaped tube radiator need not the coating anticorrosive coat, and gloss is attractive in appearance, and is prolonged anti-corrosion, has better practicability.

Fig. 1 is the structural representation (be shaped in its connecting tube 2 and connect screw thread) of the design's radiator, Fig. 2 also is the structural representation (being shaped on connecting flange 3 in its connecting tube 2) of the design's radiator, Fig. 3 is the A-A cutaway view of Fig. 1, and Fig. 4 is the B-B cutaway view of Fig. 2.Among the figure:

1, radiator body, be outer rib aluminium shaped tube

2, the connecting tube at outer rib aluminium shaped tube two-port place

3, the connecting flange in the connecting tube 2

Outer fin on J, the outer rib aluminium shaped tube 1

Bolt hole on H, the connecting flange 3

Claims (2)

1, a kind of tubular radiator is characterized in that: with the main body 1 of the outer rib aluminium shaped tube of extrusion modling (promptly be shaped on the outside wall surface of type pipe some with tube wall be the longitudinal fin J of one) as radiator, in the preparation connecting tube 2 of the two ends of this main body 1.

2, outer rib aluminium shaped tube radiator as claimed in claim 1 is characterized in that: be shaped on screw thread or the flange 3 of making to connect usefulness in connecting tube 2.
