Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator in which a convection promoting plate is attached to the radiator to increase the capacity of the radiator.

[0002]

2. Description of the Related Art A conventional radiator has a basic structure consisting of a header A, a flat tube B, and a fin C as shown in FIG. 3, but the fin portion surrounded by the fin C and the flat tube B is surrounded by the surroundings. There is little heat diffusion to, and the draft effect promotes natural convection as shown by the arrow in the figure. Due to heat transfer in other areas, the draft effect promotes natural convection in about half of the fins.
Related to this kind of structure, for example
-3327 etc. are mentioned.

[0003]

In the prior art, fins are attached for the purpose of increasing the natural convection of the radiator, but the effect of promoting the natural convection of the fins by the draft effect is as follows.
Only about half of all fins.

In the present invention, in order to promote natural convection due to the draft effect from the entire fin, and further to increase the fin area, a convection promoting plate is attached, and in addition, secondary natural convection is provided between the convection promoting plate and the wall. The purpose is to promote convection and expand the heat dissipation effect of the fins.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention encloses a flat tube and fins by attaching one or many convection promoting plates to the fin attached to the flat tube. .. This increases the draft effect in the fin portion and promotes natural convection. Further, to promote secondary natural convection between the convection promoting plate and the wall body, the distance between the convection promoting plate and the wall body is set to be equal to or less than the fin height, and the convection promoting plate and the wall body are surrounded to improve draft effect Increase.

[0006]

The convection promoting plate surrounds the flat tube and the fins to facilitate the draft effect, further increase the fin area and increase the heat radiation amount. Further, the draft effect is easily generated between the convection promoting plate and the wall body by bringing both end portions of the convection promoting plate into contact with or close to the wall body. It is to be noted that keeping the distance between the convection promoting plate and the wall below the fin height causes the flat tube and the air temperature in the part surrounded by the fin and the convection promoting plate to drop, so if the distance is increased the draft will increase. This is because the effect will not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The radiator of the present invention will be described below with reference to the illustrated embodiments. In the figure, reference numeral 1 denotes a header of a radiator, which is provided with a flat tube 2 through which warm water passes, and fins 3 are provided in contact with the flat tube 2. The header 1 and the flat tube 2 are joined by welding or the like to be integrated.

Further, the flat tube 2 and the fins 3 are joined by welding or the like so that the heat conduction between the flat tube and the fins is good. Reference numeral 4 is a hot water inlet socket projecting from the header 1, 5 is a hot water outlet socket provided in the header 1 below the hot water inlet socket 4, and 6 is an air vent valve projecting from the top of the header.

Reference numeral 7 is a convection promoting plate disposed on the surface of the fin 3, and an example of one plate is shown. However, a large number of convection promoting plates have the same effect only at necessary portions, and the structure thereof is not limited. The convection promoting plate 7 and the fins 3 are joined by welding, screws, etc.,
Both ends of the convection promoting plate 7 are bent in order to come into contact with or approach the wall 8.

FIG. 2 shows a state in which it is attached to a wall body, or attachment fittings and the like are omitted. And the floor surface 9 connected to the wall body 8
There is a gap for ventilation between the radiator and the radiator.

In the structure as described above, as in the conventional radiator shown in FIG. 3, the flat tube 2 has only the fins 3.
In the area surrounded by the fin 3 and the fins 3, natural convection is promoted by the draft effect as shown by the arrow F, but in the area not surrounded by the arrow G, heat transfer causes the effect of convection. Is reduced. In the conventional embodiment shown in FIG. 3, the draft effect can be expected only in about half of the entire fin. However, when the convection facilitating plate 7 according to the present invention is attached as shown in FIG. 1, heat is transferred and cold air enters the room due to the draft effect like 10-10 as shown in FIG. Promote.

The attachment of the convection promoting plate 7 also has the effect of increasing the area of the fin 3 portion. Further, when b ≦ a in the attached state with the wall body 8 and the convection promoting plate 7 is as shown in FIG. 2, and when it comes into contact with or comes close to the wall body, the draft effect shown by 11-11 in FIG. 2 occurs, A secondary natural convection effect will occur. This is because the relationship of b ≦ a is naturally lower in 11 than in air temperature of 10, and when b> a, the draft effect is reduced.

[0013]

According to the present invention, a convection promoting plate is attached to the fins of the radiator to increase the amount of convection heat dissipation, and further, the distance between the convection radiator plate and the wall is limited to promote secondary convection. As a result, the effect of the fins of the radiator can be increased, the heating capacity of the radiator can be increased, and secondary natural convection with the wall can be generated even when the radiator is installed. There is an effect that can be.
