The rear side panel of piece is connected with each other, thus constituting independent air channel by the first fin 3, the second fin 4 and rear side panel 5.
Because the side-walls in this air channel are in closed state, convection current therefore can be avoided further to the heat radiation of front panel 2
Caused impact, also can improve convection current performance simultaneously, thus improving the radiating efficiency of radiator further.
Alternatively, second it is fixedly connected multiple connected modes may also be employed, for example can be using clamping, grafting or overlap joint side
Formula.For example, mode can be fixedly connected using what any embodiment in Fig. 5 to Fig. 7 was related to.
Figure 12 is the schematic diagram of the another embodiment of radiating fin of the present invention.Compared with above-described embodiment, real shown in Figure 12
Apply in example, be also provided with side rib piece 6 on the second fin 4 further.
By being provided with side rib piece 6 on the second fin 4, can further improve the heat dispersion of radiating fin.
Alternatively, side rib piece 6 can be arranged in parallel with the first fin 3.
Alternatively, in the above-described embodiments, front panel 2 can be arranged in parallel with the first fin 3.
Alternatively, in the above-described embodiments, front panel 2 can be arranged in parallel with rear side panel 5.
It is uniformly arranged by above-mentioned, so that convection current is more uniform, can further improve the radiating efficiency of radiator.
The present invention also provides a kind of radiator, and this radiator includes multiple radiating fins being related to as above-mentioned any embodiment
Piece.
By using radiating fin involved in the present invention, thus effectively prevent the impact that convective heat transfer radiation causes,
Improve radiating efficiency, and improve Consumer's Experience.
Figure 13 is the schematic diagram of one embodiment of radiator of the present invention.As shown in figure 13, except in inclusion in radiator
Outside the radiating fin stated, also include at least one blower fan 7.By arranging this blower fan 7, can help to preferably in radiating fin institute
Form convection current, to improve the radiating efficiency of radiator in the air channel being formed.
In fig. 13, in radiator, the front panel 2 of radiating fin provides the user with heat radiation, passes through blower fan 7 simultaneously
Effect, forms convection current, Figure 13 in the air channel that the first fin 3 by radiating fin, the second fin 4 and rear side panel 5 are constituted
In arrow instruction convection current direction.Certainly, also dependent on need change convection current direction.
By implementing the present invention, following beneficial effect can be obtained：
The radiating of radiator to be realized mainly by the heat radiation of front panel, but front panel is due to the thermal resistance of material
There is certain limitation, thus result in the partial heat in thermal source and can not exhale the other ribs it is therefore desirable in radiating fin
Piece and rear side panel are radiated.Because the other fins in radiating fin and rear side panel can form air channel in radiating, and
Convection current in air channel can interfere to the heat radiation of front panel, therefore has influence on radiating efficiency and users'comfort.
In order to avoid this problem, the present invention proposes to be isolated heat radiation with the convection current in air channel, thus ensure that scattered
The thermal efficiency and users'comfort.
Further, since the heat radiation in the present invention is isolated with convection current, and air channel can be able to be airtight with side wall
, therefore can realizing strengthening convection current in air channel by blower fan, heat dissipation capacity being further enhanced, thus improving the comfortable of user
Degree.
According to the supply water temperature of national regulation radiator heating, design supply and return water temperature typically now is 80 DEG C/60 DEG C.
But be conducive to now with source heat pump heat, industry preheating thermal source, solar source etc. the low-temperature heat source of energy-conserving and environment-protective opening and
The progressively popularization and application of heating cause, the hot water temperature for end more and more lower so that traditional heat sinks end heating equipment with
And not enabling the benefit of due function and energy-conserving and environment-protective, low-grade heat source is difficult to directly utilize.
And in the present invention, by being isolated heat radiation and convection current, thus avoiding caused by convective heat transfer radiation
Impact, realizes forced convertion by blower fan simultaneously, increased the heat sinking function of radiator, and can be adjusted by force by controlling blower fan
Convection intensity processed, meets user's request so as to preferably be applied to low temperature water supply, is conducive to the exploitation of low-grade heat source.
Description of the invention is given for the sake of example and description, and is not exhaustively or by the present invention
It is limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Select and retouch
Stating embodiment is in order to the principle of the present invention and practical application are more preferably described, and so that those of ordinary skill in the art is managed
The solution present invention is thus design is suitable to the various embodiments with various modifications of special-purpose.
