Abstract
The utility model provides a novel fin. The novel fin is characterized by comprising two one-sided fins (1) which are arranged symmetrically to be integrally H-shaped, a fillet (3) is formed on each one-sided fin (1), and a heat exchange tube matching notch (2) is formed on each one-sided fin (1). With the fillet design, on the premise of not affecting the heat exchange efficiency of the fined tube bundle, the consumption of fin materials is reduced, the total weight of a heat exchanger is reduced, the heat exchange efficiency per unit weight is increased, and the electrode of a welding machine is protected from being worn by the H-shaped finned tube bundle during butt welding.
Description
Technical field
The utility model relates to a kind of novel H type finned tube and uses fin, is used for present coal-fired boiler in power plant flue and processes with H type finned tube with afterheat heat exchanger.
Background technology
At present, be used for coal-fired power plant's smoke gas afterheat heat exchanger and all gradually adopt H type finned tube group, changing the pipe group, to have a dust stratification few, and the flow of flue gas resistance is little, advantage such as compact conformation, weight of equipment are light.And heavy at H type finned tube group smoke gas afterheat heat exchanger, the shared heat exchanger gross weight of H type fin over half so H type fin itself is designed, can reach the reduction gross weight of equipment, and the optimizing equipment structure improves the Unit Weight heat exchange efficiency.Existing H type fin is the rectangle design, and fin is 90 ° of right-angle design for four jiaos.Fin welds through H type finned tube intermediate frequency welding machine and heat exchanger tube.
Summary of the invention
The purpose of the utility model provides a kind of novel fin, can under the prerequisite that guarantees heat exchange area, reduce the material utilization rate, thereby reduce gross weight of equipment.
The technical scheme of the utility model is:
A kind of novel fin comprises 2 symmetrically arranged one-sided fins, and integral body is the H type, and each one-sided fin is provided with fillet.
Said one-sided fin is provided with heat exchanger tube coupling breach.
Novel fin adopts the fillet design for four jiaos.Promptly carry out the fillet Design and Machining, save the fin manufacturing materials in the fin outside.
The beneficial effect of the utility model is:
The novel fin of the utility model improves the Unit Weight heat exchange efficiency guaranteeing to reduce weight of equipment under the heat exchange area prerequisite.And flue gas is on being flushed in fin the time; Owing to adopt the fillet design; Lowered flue gas resistance, reduced the wearing and tearing of fin four corners position, and adopted the intermediate frequency welding to carry out butt-joint in the finned tube group to add man-hour; Reduced the extrusion abrasion of four angle-butt weld machine electrodes, the service life of having improved electrode welder.
It adopts the fillet design the novel fin of the utility model; Under the prerequisite that does not influence finned tube group heat exchange efficiency, can practice thrift the fin rapidoprint, alleviate the heat exchanger gross weight; Improve the Unit Weight heat exchange efficiency, and reduce the wearing and tearing that the butt-joint of H type finned tube group adds butt welding machine electrode in man-hour.
Description of drawings
Fig. 1 is the planar structure sketch map of the utility model.
Fig. 2 is the perspective view of the utility model.
Among the figure: 1 is that one-sided fin, 2 is fillet for heat exchanger tube matees breach, 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1 to 2,
1.A kind of novel fin comprises 2 symmetrically arranged one-sided fins 1, and integral body is the H type, and each one-sided fin 1 is provided with fillet 3.
One-sided fin 1 is provided with heat exchanger tube coupling breach 2.
Novel fin adopts the fillet design for four jiaos.Promptly carry out the fillet Design and Machining, save the fin manufacturing materials in the fin outside.Punch press adds to be handled carrying out fillet around the fin man-hour.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Do not breaking away under the utility model design concept prerequisite; Common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model, and the technology contents that the utility model is asked for protection all is documented in claims.
Claims (2)
1. a novel fin is characterized in that comprising 2 symmetrically arranged one-sided fins (1), and integral body is the H type, and each one-sided fin (1) is provided with fillet (3).
2. novel fin according to claim 1 is characterized in that said one-sided fin (1) is provided with heat exchanger tube coupling breach (2).
