Abstract

The utility model discloses an aluminium radiator for hot water boiling or steam heating, which has the advantages of better radiation effect and non-perishable deformation of the radiating pipe. The utility model comprises a water inlet pipe 1, a water return pipe 2, a flat aluminium radiating pipe 3, a water header 4 and a vent valve 5. The utility model is characterized in that two opposite walls of four walls of the flat aluminium radiating pipe 3 are planes; at least one of another two opposite walls is a curved surface.

Description

High-effect aluminium radiator

The utility model relates to a kind of radiator, particularly about a kind of hot water or steam heating aluminium radiator.

At present, known aluminium radiator, the cross section of its radiating tube is a square or rectangular.Its existing problems and weak point are: one, and heating agent and radiating tube inwall contact-making surface are less, and the coefficient of heat transfer is less, and radiating effect is relatively poor; Its two, mechanical strength is low, radiating tube easily deforms etc.

The purpose of this utility model is to overcome above-mentioned problems of the prior art and weak point and a kind of heating agent and radiating tube inwall contact area increases, radiating tube is difficult for deforming novel flat aluminum pipe radiator are provided.

The purpose of this utility model can reach by following measure: it has water inlet pipe 1, return pipe 2, flat aluminum pipe radiating tube 3, water manifold 4, vent valve 5.Its improvements are in four walls of flat aluminum pipe radiating tube 3, and it is the plane that two relative walls are arranged, and have at least one to be curved surface in two other relative wall.

Can also reach by following measure: have at least the inner surface of a wall to have in said two relative walls that have a curved surface at least along the axial rib 6 of radiating tube 3.

Can also reach by following measure: the cross section of the curved wall of said radiating tube 3 has trapezoidal to radiating tube 3 indents at least.

Can also reach by following measure: the cross section of the curved wall of said radiating tube 3 has trapezoidal to radiating tube 3 evaginations at least.

Can also reach by following measure: the cross section of the curved wall of said radiating tube 3 has an arc to radiating tube 3 evaginations at least.

Can also reach by following measure: the cross section of the curved wall of said radiating tube 3 has an arc to radiating tube 3 indents at least.

Can also reach by following measure: the cross section of the curved wall of said radiating tube 3 has a zigzag to radiating tube 3 evaginations at least.

Can also reach by following measure: the cross section of the curved wall of said radiating tube 3 has a zigzag to radiating tube 3 indents at least.

Can also reach by following measure: the face at two inequilateral places of said flute profile water manifold 4 is the plane.

Compared with the prior art the utility model has following advantage and actual effect:

1, (cross section of curved wall can be trapezoidal to have one or two curved wall in four walls of flat aluminum pipe radiating tube of the present utility model, it also can be arc, also can be zigzag), and the tube wall inwall has rib, therefore with respect to square flat aluminum pipe radiator, increase heat medium pipe inwall contact area, improved coefficient of heat transfer, radiating effect is better, shows that according to test heat dissipation capacity has improved more than 20%;

2,, show that according to test metal thermal intensity has improved about 0.5 etc. because the change of the utility model shape has improved the mechanical strength of self, and radiating tube is difficult for deforming.

The utility model embodiment in conjunction with the accompanying drawings is described further:

Fig. 1, Fig. 2, Fig. 3 provide first embodiment.As can be seen from Fig. 3, the cross section of radiating tube 3 curved walls is concave trapezoidal, certainly, also can make cambered outwards trapezoidal.The curved wall inwall has some ribs 6.It comprises water inlet pipe 1, return pipe 2, flat aluminum pipe radiating tube 3, inequilateral flute profile water manifold 4, vent valve 5.Two inequilateral place faces of wherein said flute profile water manifold 4 are the plane.The oblique angle is cut at radiating tube 3 two ends, this oblique angle is consistent with two formed inclination angles of inequilateral line of unequal-sided flute profile water manifold, radiating tube 3 is transversely arranged, the oblique angle of radiating tube 3 is cut in the same side, weld together then, inequilateral flute profile water manifold 4 is welded at radiating tube 3 two ends behind.Other is a known technology, so do not narrate.

Fig. 1, Fig. 2, Fig. 4 provide second embodiment.From Fig. 4 as seen, the cross section of radiating tube 3 curved walls is cambered outwards arc, certainly, also can make the arc that concaves.The curved wall inwall has some ribs 6, omits among Fig. 4.All the other are identical with first embodiment.

Fig. 1, Fig. 2, Fig. 5 provide the 3rd embodiment.From Fig. 5 as seen, the cross section of radiating tube 3 is cambered outwards zigzag, certainly, also can make the zigzag that concaves.The curved wall inwall has some ribs 6, omits among Fig. 5.All the other are identical with first embodiment.
