Abstract
The utility model discloses a kind of automatically cleaning radiating fin radiator, belong to heat exchanger technology field, comprise be arranged on base (3) radiating fin, described radiating fin is the bimetallic composite radiating fin be made up of upper sheet metal (1) and lower sheet metal (2), and upper sheet metal (1) and lower sheet metal (2) fit together and be bending; Wherein, upper sheet metal (1) and lower sheet metal (2) are for having the sheet metal of different thermal coefficient of expansions; Under non operating state, bimetallic composite radiating fin holds its shape shape, under operating state, raises with temperature, bimetallic composite radiating fin is in the bending launched; In the course of the work, bimetallic radiating fin is by the impact of temperature, and the change of shape can occur for self, make radiating fin be in continuous motion state, there is the effect of brushing lightly and stroking dust, i.e. self-cleaning function, prevent stockpiling of dust, there is more area of dissipation and better radiating effect.
Description
Technical field
The utility model relates to a kind of radiator, and specifically a kind of automatically cleaning radiating fin radiator, belongs to heat exchanger technology field.
Background technology
The heater members of the various electronic equipments in heat-exchange apparatus technical field, all needs to install various radiator and dispels the heat.As everyone knows, the convection transfer rate between air and metal is very little, so need the heat exchange area increasing air side, thus reduces thermal resistance, strengthens heat transfer effect.Way common is at present that the periphery of radiator is manufactured fin shape, 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 the flowing of radiator ambient air, takes away more heat, strengthen radiating effect.
Above-mentioned radiator, in application process, is easy between fin and fin deposit dust, causes heat dispersion to decline, cooled object Yin Gaowen can be caused time serious to burn.Under the application conditions having fan enhance heat, the dust of deposition can be blown out by radiator fan, affects health.
For preventing dust to the harm of human body, normally by improving the installation form of Air Filter, by the dust isolation in air-flow, thus reducing the dust entering radiator, reaching dust-proof effect.But what adopt is dust-proof partition means, and what can not alleviate the radiating fin of spreader surface is stained with grey characteristic, and the dust failing to completely cut off still can stick in spreader surface, can form dust accumulation equally, greatly reduce radiating efficiency.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model 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 adopted in the utility model is: a kind of automatically cleaning radiating fin radiator, comprise be arranged on base radiating fin, described radiating fin is the bimetallic composite radiating fin be made up of upper sheet metal and lower sheet metal, and upper sheet metal and lower sheet metal fit together and be 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, bimetallic composite radiating fin holds its shape shape, under operating state, raises with temperature, bimetallic composite radiating fin is in the bending launched.
Bimetallic composite radiating fin is U-shaped.
Also comprise the enhanced heat exchange operating state be made up of bimetallic composite radiating fin, base and radiator fan.
Compared with existing radiator: the bimetallic composite radiating fin that the utility model adopts sheet metal and lower sheet metal to form, wherein sheet metal has different thermal coefficient of expansions, in the course of the work, bimetallic radiating fin is by the impact of temperature, can be there is the change of shape in self, make radiating fin be in continuous motion state, have the effect of brushing lightly and stroking dust, i.e. self-cleaning function, prevents stockpiling of dust; Fit together due to sheet metal and lower sheet metal and be bending, in limited space, extend the length of fin, there is more area of dissipation, enhance radiating effect.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 2 and 3, a kind of automatically cleaning radiating fin radiator, comprise setting on the base 3 radiating fin, described radiating fin is the bimetallic composite radiating fin be made up of upper sheet metal 1 and lower sheet metal 2, and upper sheet metal 1 and lower sheet metal 2 fit together and be 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; Link together between bimetallic composite radiating fin and base 3, during work, base 3 contacts together with by thermal dissipating object, and heat is distributed by base 3 and bimetallic radiating fin.
Wherein, bimetallic composite radiating fin shape is bending, and can be U-shaped but not limit to U-shaped also can be other forms; U-shaped radiating fin extends 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 transmitted to base 3 from by thermal dissipating object, bimetallic radiating fin receives and conducts from base 3 the heat of coming, own temperature increases, because upper sheet metal 1 and lower sheet metal 2 have different thermal coefficient of expansions, open from initial U-shaped after being heated, become the shape shown in Fig. 4, the Curved namely opened.
With reference to shown in Fig. 2 and Fig. 4: when non operating state and operating state, radiating fin is from U-shaped to the shape opened, radiating fin spacing can great changes will take place, radiating fin is made to be in continuous motion state, brush lightly the effect of stroking, therefore can prevent 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, be made up of upper sheet metal 1 and lower sheet metal 2, base 3 and radiator fan 4, radiator fan 4 can accelerate the flowing of wind speed, strengthens the radiating effect of automatically cleaning radiating fin.
