Abstract

The utility model relates to an embedded type double-metal rolled high-efficiency fin pipe for an air cooler. A base pipe of the fin pipe is provided with a notch of 0.1 to 3 mm, and the notch is spiral or circular, a part provided with the notch and a part which is not provided with the notch are covered with aluminum pipes, and fins are manufactured on the aluminum pipes. Compared with the prior fin pipe, the embedded type double-metal rolled fin pipe has good heat transfer effect and high corrosion resisting capability and is applicable to higher temperature media, thereby improving the cooling capability and the service life of the air cooler and ensuring the safety of the air cooler at high temperature.

Description

A kind of air cooler rolling high-efficiency fin pipe of mosaic bimetallic
Technical field
The utility model relates to a kind of industries such as oil, chemical industry, metallurgy, electric power that are applied to, and finishes the heat exchange software of medium cooling, a kind of specifically air cooler rolling high-efficiency fin pipe of mosaic bimetallic.
Background technology
At present, the applied finned tube form of known air cooler mainly contains around sheet (L type), annular knurl rolls sheet (DR type) and empiecement (G type) around sheet (KL type), bimetallic, and these finned tubes all have introduction in GB15386 and API661, be commonly used.It mainly is to use fin to strengthen the heat transfer of air side, but the serviceability temperature of L type, KL type, DR type is all lower, and because fin heat resistance is bigger, so some operating mode must adopt G type finned tube.Heat transfer coefficient is the highest in theory for G type finned tube, can be high temperature resistant, and it is that parent tube is slotted earlier, then aluminium strip is inlayed in the groove.In fact make very difficulty, can't guarantee that aluminium strip inlays in the groove.So can not guarantee its performance, because the parent tube of G type finned tube exposes in atmosphere, be easy to corrosion again.
The utility model content
Technical problem to be solved in the utility model is: improve the heat-transfer effect and the resistance to corrosion of air cooler finned tube, thereby improve the cooling capacity and the life-span of air cooler, the safety under the high temperature of assurance air cooler.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: provide a kind of mosaic bimetallic rolling high-efficiency fin pipe, this finned tube parent tube fluting 0.1~3mm, fluting is screw type or annular, partly cover aluminum pipe at slotted section and unslotted, on aluminum pipe, manufacture fin.
Operation principle of the present utility model is: in pipe during high-temperature medium, air is during by fin, because the finned tube parent tube is slotted, what fin was firm is set in the parent tube, so improved serviceability temperature, has also reduced fin gap thermal resistance, has improved finned tube efficient.
Description of drawings
Fig. 1 is the schematic diagram of a kind of air cooler of the utility model with the rolling high-efficiency fin pipe of mosaic bimetallic;
Specific embodiments
1 is the parent tube of finned tube in the accompanying drawing 1, and its effect is inner for medium inflow and outflow, and 2 are fluting, 3 aluminum pipes for covering, and 4 is fin, and 3 and 4 is one, and elder generation penetrates parent tube aluminum pipe then with the parent tube fluting, rolls out finned tube with special equipment.The parent tube of finned tube can be any material, and fin is generally aluminium.What provide in the accompanying drawings is a specific embodiment, and groove is a rectangle.Groove can also be V-arrangement, U-shaped or other curved shape.
The utility model is compared with known common air cooler, owing to open at the parent tube of bimetal rolled finned Groove has formed mosaic texture, and fin improves the heat transfer coefficient of air side in conjunction with more firm, has improved fin The serviceability temperature of pipe, parent tube no longer are exposed in the atmosphere, have improved resistance to corrosion, and have kept bimetallic The strong character of rolled finned tube.
The utility model is made simple, and unit heat exchange amount metal consumption is few, reaches the manufacturing equipment expense of saving With, the purpose of raising cooling effect.
Therefore the utility model advanced person, reliable can be widely used in the fields such as oil, chemical industry, can Promote the use of.

Claims (3)

1. an air cooler is made up of parent tube and fin with the rolling high-efficiency fin pipe of mosaic bimetallic, and feature is to slot on parent tube, and outer side covers aluminum pipe, aluminum pipe are set in the groove, forms mosaic texture, rolls out fin on the aluminum pipe.
2. a kind of air cooler according to claim 1 is characterized in that with the rolling high-efficiency fin pipe of mosaic bimetallic fluting can be a spirality, also can be annular.
