Abstract
The invention discloses a radiator with self-cleaning radiating fins, and belongs to the technical field of heat exchangers. The radiator comprises radiating fins arranged on a base (3). The radiating fins are bimetal composite radiating fins, each of which is composed of an upper metal piece (1) and a lower metal piece (2) which fit closely into a bent shape and are metal sheets with different thermal expansion coefficients. In a non-working state, the bimetal composite radiating fins are kept in the original shape. In a working state, the bimetal composite radiating fins unfold into a bent shape as the temperature rises. In the working process, the shape of the bimetal composite radiating fins changes under the temperature effect, so that the radiating fins are in a constant motion state and thus has a dust blowing effect, namely, a self-cleaning function. Therefore, dust accumulation is prevented, and the radiator has a larger radiating area and a better radiating effect.
Description
Technical field
The present invention relates to a kind of radiator, specifically a kind of automatically cleaning radiating fin radiator, belongs to heat exchanger technical field.
Background technology
The heater members of the various electronic equipments in heat-exchange apparatus technical field, all needs to install various radiators and dispels the heat.As everyone knows, the convection transfer rate between air and metal is very little, thus need to increase the heat exchange area of air side, thus reduce thermal resistance, strengthen heat transfer effect.Common way is that the periphery of radiator is manufactured to fin shape at present, and in order to increase area of dissipation, modal flat fin structure radiator as shown in Figure 1.In some cases, above-mentioned radiator is auxiliary with radiator fan again, accelerates radiator ambient air and flows, and takes away more heat, strengthens radiating effect.
Above-mentioned radiator, in application process, is easy to deposit dust between fin and fin, cause heat dispersion to decline, and when serious, can cause the object Yin Gaowen that is cooled to burn.Having under the application conditions of fan enhance heat, the dust of deposition can be blown out by radiator fan, affects health.
For preventing the harm of dust to human body, normally by improving the installation form of Air Filter, by the dust isolation in air-flow, thereby reduce the dust that enters radiator, reach dust-proof effect.But what adopt is dustproof partition means, can not alleviate spreader surface radiating fin be stained with grey characteristic, fail isolated dust still can stick in spreader surface, can form equally dust accumulation, greatly reduce radiating efficiency.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of automatically cleaning radiating fin radiator, can effectively prevent stockpiling of dust, simultaneously can increasing heat radiation area to strengthen radiating effect.
To achieve these goals, the technical solution used in the present invention is: a kind of automatically cleaning radiating fin radiator, comprise be arranged on base radiating fin, the serve as reasons bimetallic composite radiating fin of upper sheet metal and lower sheet metal composition of described radiating fin, upper sheet metal and lower sheet metal fit together and are bending; Wherein, upper sheet metal and lower sheet metal are sheet metal, have two kinds of different thermal coefficient of expansions; Under non operating state, the bimetallic composite radiating fin shape that holds its shape, under operating state, with the bending that temperature raises, bimetallic composite radiating fin is expansion.
Bimetallic composite radiating fin is U-shaped.
Also comprise the enhanced heat exchange operating state being formed by bimetallic composite radiating fin, base and radiator fan.
Compared with existing radiator: the present invention adopts the bimetallic composite radiating fin of upper sheet metal and lower sheet metal composition, wherein sheet metal has different thermal coefficient of expansions, in the course of the work, bimetallic radiating fin is subject to the impact of temperature, self can there is the variation of shape, make radiating fin in continuous motion state, have and brush lightly the effect of stroking dust, be self-cleaning function, prevent stockpiling of dust; Because sheet metal and lower sheet metal fit together and be bending, the length of having extended fin in limited space, has more area of dissipation, has strengthened radiating effect.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 2 and 3, a kind of automatically cleaning radiating fin radiator, comprise be arranged on base 3 radiating fin, the described radiating fin bimetallic composite radiating fin that upper sheet metal 1 and lower sheet metal 2 form of serving as reasons, upper sheet metal 1 and lower sheet metal 2 fit together and are bending; Wherein, upper sheet metal 1 and lower sheet metal 2 are for having the sheet metal of two kinds of different thermal coefficient of expansions; Between bimetallic composite radiating fin and base 3, link together, when work, base 3 is with together with heat radiation object contact, and heat distributes by base 3 and bimetallic radiating fin.
Wherein, bimetallic composite radiating fin shape is bending, can be for U-shaped but do not limit to U-shaped also can be for other forms; U-shaped radiating fin has extended the length of fin in limited space, has more area of dissipation, therefore can strengthen radiating effect.
As shown in Figure 4: non operating state holds its shape; In the course of work, heat is from being transmitted to base 3 by heat radiation object, bimetallic radiating fin receives the heat coming from base 3 conduction, self temperature increases, because upper sheet metal 1 and lower sheet metal 2 have different thermal coefficient of expansions, after being heated, open from initial U-shaped, become the shape shown in Fig. 4, the Curved of opening.
Shown in Fig. 2 and Fig. 4: in the time of non operating state and operating state, radiating fin is from U-shaped to the shape of opening, radiating fin spacing can great changes will take place, make radiating fin in continuous motion state, brush lightly the effect of stroking, therefore can prevent that dust from continuing to assemble on radiating fin, there is self-cleaning function.
As Fig. 5 provides a kind of operating state of enhanced heat exchange mode, formed by upper sheet metal 1 and lower sheet metal 2, base 3 and radiator fan 4, radiator fan 4 can be accelerated flowing of wind speed, strengthens the radiating effect of automatically cleaning radiating fin.
