Abstract
The utility model discloses a kind of electric heater fin and electric heater, belong to fin technical field, designing for solving the problems such as existing fin area of dissipation is little, radiating efficiency is low.A kind of electric heater fin, comprises heat sink body and along the outwardly directed multiple radiating fin of described heat sink body both sides difference, each described radiating fin two sides is equipped with multiple groove and projection, for increasing the area of dissipation of fin.This fin good heat dissipation effect, heat radiation more abundant.A kind of electric heater, described electric heater is provided with multiple above-mentioned fin, and this electric heater radiating efficiency is high, good heat dissipation effect.
Description
Technical field
The utility model relates to fin technical field, is specifically related to a kind of electric heater fin and has the electric heater of this fin.
Background technology
Utilize fin to be also the most basic technical approach to increase the area of heat radiation be the most common in thermal management technology, the trend increased along with electronic device heat generation density, the demand of heat radiation increases day by day, also more and more stricter to the cooling requirements of fin.
At present, the fin overwhelming majority is all have radiating fin the both sides of heat radiator body are protruding, and this radiating fin is usually in straight-tooth shape, and the fin area of dissipation of this structure is limited, radiating effect is not good, needs to improve in configuration aspects.
Utility model content
An object of the present utility model is that a kind of area of dissipation of proposition is larger, dispel the heat electric heater fin more fully.
Another object of the present utility model is that a kind of radiating efficiency of proposition is high, the electric heater of good heat dissipation effect.
For reaching this object, on the one hand, the utility model is by the following technical solutions:
A kind of electric heater fin, comprises heat sink body and along the outwardly directed multiple radiating fin of described heat sink body both sides difference, each described radiating fin two sides is equipped with multiple groove and projection, for increasing the area of dissipation of fin.
As a preferred version of the present utility model, the cross section of each described radiating fin is cambered surface, and the angle between its bottom and described heat sink body is acute angle or obtuse angle.
As a preferred version of the present utility model, each described radiating fin is all interval with described groove and described projection on the two sides along described heat sink body axis.
As a preferred version of the present utility model, described groove is deep-slotted chip breaker, and described projection is arc convex.
As a preferred version of the present utility model, each described radiating fin in the two sides along described heat sink body axis all in wavy surface.
On the other hand, the utility model is by the following technical solutions:
A kind of electric heater, described electric heater is provided with multiple above-mentioned fin.
The structure of electric heater fin to radiating fin that the utility model provides is improved, and being designed to by radiating fin is arcuate structure from the side, is wavy shaped configuration, increases area of dissipation viewed from front, makes the heat radiation of this fin more abundant.
The electric heater that the utility model provides is provided with multiple fin, and radiating efficiency is improved, radiating effect is better.
Accompanying drawing explanation
Fig. 1 is the front view of the electric heater fin that the utility model preferred embodiment one provides;
Fig. 2 is the partial enlarged drawing of part A in Fig. 1;
Fig. 3 is the top view of the electric heater fin that the utility model preferred embodiment one provides;
Fig. 4 is the partial enlarged drawing of part B in Fig. 3.
Be labeled as in figure:
1, heat radiator body; 2, radiating fin; 21, groove; 22, protruding.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Preferred embodiment one:
This preferred embodiment discloses a kind of electric heater fin.As shown in Figure 1, this electric heater fin comprises heat sink body 1 and distinguishes outwardly directed multiple radiating fin 2 along heat sink body 1 both sides, each radiating fin 2 two sides are equipped with multiple groove 21 and protruding 22, for increasing the area of dissipation of fin.
Concrete, the cross section of each radiating fin 2 is cambered surface, and the angle between its bottom and heat sink body 1 is acute angle or obtuse angle.Two sides along heat sink body 1 axis are all interval with groove 21 and protruding 22, in the present embodiment, groove 21 is deep-slotted chip breakers, protruding 22 is arc convex, this deep-slotted chip breaker and this arc convex interval close-packed arrays thus forming wavy surface respectively along the two sides of heat sink body 1 axis, the wavy surface that these two sides are formed can be the consistent wavy surface of ripple glaze, also can be the inconsistent wavy surface of ripple glaze.Fin entirety is curved from the side, undulate viewed from front, good looking appearance, generous.
Above-mentioned fin is processed by shovel piece formula and one-body molded, and manufacturing procedure is simple.This fin is larger than existing fin area of dissipation, heat radiation is more abundant.
Preferred embodiment two:
This preferred embodiment discloses a kind of electric heater fin, and its structure is substantially identical with preferred embodiment one.This electric heater fin comprises heat sink body and along the outwardly directed multiple radiating fin of heat sink body both sides difference, each radiating fin two sides is equipped with multiple groove and projection, for increasing the area of dissipation of fin.
Difference is: the structure of radiating fin is not limited to the structure that cross section is cambered surface, can also be other curved-surface structures, as long as can meet increasing heat radiation area; It is arcuate structure that groove and projection are also not limited to, and can also be V-arrangement or trapezium structure, can meet increasing heat radiation area.
Preferred embodiment three:
This preferred embodiment discloses a kind of electric heater, and this electric heater includes multiple fin as described in preferred embodiment one or preferred embodiment two, and this electric heater good heat dissipation effect, radiating efficiency are high.
Below by reference to the accompanying drawings embodiment of the present utility model is described; but the utility model is not limited to above-mentioned detailed description of the invention; those skilled in the art is not departing under the ambit that the utility model aim and claim protect; also can obtain a lot of form, these are all within protection domain of the present utility model.
