Abstract

A steel tube with cast fins is provided, which relates to a tube for heat dissipation, aiming to solve the problems of the prior heating pipe free of fins, such as small heat dissipation area and low heat dissipation efficiency; and the problems of the prior tube with fins, such as fault connection between fins and tube and poor heat transfer effect. The steel tube with cast fins comprises a tube (1) and fins (2) cast on the outer wall of the tube (1), wherein the fin is square and has a central opening for allowing the tube to pass therethrough. The fins (2) are cast on the outer wall of the tube (1), thereby simplifying the manufacturing process. Compared with the prior welding process, the casting process is suitable for fins of larger sizes. The fin is structured to be square to increase the heat dissipation area and to facilitate the preservation of tubes with square fins. A connection bar is arranged between two adjacent fins to tighten the fins.

Description

Have the steel pipe of casting the wing

Technical field: the utility model relates to a kind of pipe of heat transmission.

Background technology: be not provided with fin on the heating installation pipe, exist little, the inefficient problem of area of dissipation, and have the pipe of fin because fin area is little, radiating efficiency is low, owing to is connected badly between fin and the pipe, so heat-transfer effect is bad, same influence is dispelled the heat again.

The utility model content: the purpose of this utility model is to provide a kind of area of dissipation big and heat-transfer effect is good has the steel pipe of casting the wing, and it comprises pipe 1, is connected to fin 2 at the outer wall direct casting of pipe 1, and fin 2 has the square of pipe perforation for the center.Advantage of the present utility model is: fin 2 castings are connected on the outer wall of pipe 1, it is succinct that it has reduced technological process and the operation made, compare with welding manner, casting connects mode and can bear more large-area fin, casting connects mode and bears more than the twice that the diameter of fin is a welding manner, fin is set to square, compare with circle, square have a bigger area of dissipation, and the pipe that has square fin is taken care of easily and is laid, be provided with connection strap between adjacent fins, connection strap plays the effect that makes fin firmer.

Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the structural representation of the specific embodiment two, and Fig. 4 is the vertical view of Fig. 3.

The specific embodiment one: with reference to Fig. 1, Fig. 2, present embodiment comprises pipe 1, is connected to fin 2 at the outer wall direct casting of pipe 1, and described fin 2 has the square of pipe perforation for the center, fin 2 is aluminum products, light, the good heat dissipation effect of body, casting connect mode and can make and be connected more firmly between fin and the pipe, make heat transfer effect better, pipe 1 is a steel pipe, steel pipe has extremely strong barotolerance, is not easy to damage, can be according to the dimensioned manufacturing of user's needs.

The specific embodiment two: with reference to Fig. 3, Fig. 4, what present embodiment and the specific embodiment one were different is, fin 2 is a rectangle, on the minor face of two adjacent fins 2, be connected with connection strap 3, connection strap 3 play make fin firmer, prevent the effect that fin fractures, so rectangular long limit can be long slightly, area of dissipation can be bigger and can not fractures like this.

Claims

1, a kind of steel pipe of casting the wing that has, it comprises pipe (1), it is characterized in that being connected to fin (2) at the outer wall direct casting of pipe (1), described fin (2) has the square of pipe perforation for the center.

2, the steel pipe of casting the wing that has according to claim 1 is characterized in that the described square square or rectangular that is.

3, the steel pipe of casting the wing that has according to claim 1 is characterized in that being connected with connection strap (3) between adjacent two fins (2).
