Description
Technical field
The utility model relates to field of lighting devices, is specifically related to a kind of high thermal louver.
Background technology
Light fixture is when luminescence, and the temperature of himself can raise gradually, in continuous firing process, if the heat that light fixture produces cannot leave in time, affects the service life of light fixture by causing light fixture to be damaged.Existing light fixture dispels the heat by polylith fin usually, and its radiating effect is relatively poor, and makes lamp assembled process loaded down with trivial details.
Utility model content
In view of this, the purpose of this utility model is to provide the simple high thermal louver of a kind of structure.
The utility model is solved the problem by following technological means: a kind of high thermal louver, comprise light fixture and be connected with light fixture and the selfexcited oscillating-flow heat pipe of bending repeatedly, described selfexcited oscillating-flow heat pipe side is provided with evaporimeter, opposite side is provided with condenser, in described selfexcited oscillating-flow heat pipe, pipeline bearing of trend is provided with multiple rack, described rack comprises upper filter screen and lower filter screen, and described upper filter screen, lower filter screen and selfexcited oscillating-flow heat pipe inwall form the chamber for placing solid particle.
Further, described selfexcited oscillating-flow heat pipe comprises the extra heavy pipe body and capillary base that alternately connect.
Further, filter is provided with in described chamber.
The beneficial effects of the utility model: high thermal louver of the present utility model, comprise light fixture and be connected with light fixture and the selfexcited oscillating-flow heat pipe of bending repeatedly, described selfexcited oscillating-flow heat pipe side is provided with evaporimeter, opposite side is provided with condenser, in described selfexcited oscillating-flow heat pipe, pipeline bearing of trend is provided with multiple rack, described rack comprises upper filter screen and lower filter screen, and described upper filter screen, lower filter screen and selfexcited oscillating-flow heat pipe inwall form the chamber for placing solid particle.This high thermal louver has the simple and advantage of good heat dissipation effect of structure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plane of selfexcited oscillating-flow heat pipe.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in Figure 1-2: a kind of high thermal louver, comprise light fixture 1 and be connected with light fixture and the selfexcited oscillating-flow heat pipe 2 of bending repeatedly, described selfexcited oscillating-flow heat pipe side is provided with evaporimeter 3, opposite side is provided with condenser 4, in described selfexcited oscillating-flow heat pipe, pipeline bearing of trend is provided with multiple rack, described rack comprises upper filter screen 5 and lower filter screen 6, described upper filter screen, lower filter screen and selfexcited oscillating-flow heat pipe inwall formed for placing solid particle 7(millimeter or micron order) chamber.Radiation processes is: the heat that light fixture produces passes to selfexcited oscillating-flow heat pipe, working media is packaged with in selfexcited oscillating-flow heat pipe, working media forms liquid in pipe, plunger between vapour phase, in evaporator end, working media is heated, cause air bubble expansion, and promote liquid-vapour plug flow to condenser break condensation shrink, utilize the Convective Heat Transfer between the two-phase fluid of Three Dimensional Transient Phase Transformation Process and selfexcited oscillating-flow heat pipe wall to dispel the heat, because liquid-vapour plunger is interspersed, thus in pipe, produce strong reciprocating vibration motion, this makes Convective Heat Transfer greatly strengthen because being subject to the effect of violent Pulsating Flow, simultaneously, when liquid phase working media flows through rack, between solid particle and solid particle, between solid particle and liquid, the interphase interaction of solid particle and selfexcited oscillating-flow heat pipe and collision, make liquid cross-sectional VELOCITY DISTRIBUTION smooth, decrease laminar sublayer, enhance flow turbulence intensity, heat conduction and heat-sinking capability are promoted further, in addition, compare and directly in liquid phase working media, add solid particle, under the restriction of rack, can effectively avoid solid particle because being subject to electrostatic force, brown force etc. act on and accumulate in generation wearing and tearing and clogging together.Therefore the high thermal louver of this structure, not only structure is simple, and heat dispersion is superior.
As the further improvement of technique scheme, described selfexcited oscillating-flow heat pipe comprises the extra heavy pipe body 21 and capillary base 22 that alternately connect.So constitute the selfexcited oscillating-flow heat pipe of nonuniform section, make tube fluid along extra heavy pipe body rapid expanding after evaporator end is heated, and flow to condenser, after condenser end condensation, flow back to evaporator end along capillary base, this effectively improves the circulation power of working media, improves heat-sinking capability.
As the further improvement of technique scheme, in described chamber, be provided with filter 8.Filter can avoid solid particle to flock together further.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
