Abstract

The utility model discloses a cylindrical wind cooling radiation device, which comprises a radiation base and radiation fins (1). The radiation base is formed by enclosing a box-shaped structure with an inner cavity (4) with a cover (2) with an air hole and a bottom plate (3). A radiation fan (5) is arranged inside the inner cavity (4), the air hole arranged on the cover (4) is formed by a plurality of arc-shaped holes (6) distributed on the cover (2) at positions of a plurality of concentric circles with increasing radiuses. Each radiation fin (1) is in a cylindrical shape. A plurality of radiation fins (1) with different diameters are embedded and sleeved at the top surface of the cover (2) in a concentric mode. The cylindrical wind cooling radiation device is reasonable in structure, excellent in radiation performance, novel in shape and adaptable to requirements for more application.

Description

Cartridge type wind-cooling heat dissipating device
Technical field
The utility model relates to the radiating appliance field, and particularly a kind of LED lamp with fan is used heat abstractor.
Background technology
Light emitting diode is as a kind of new light sources, and its basic principle of luminosity is to emit excess energy in the carrier recombination process in the semiconductor, causes photo emissions and electric energy is converted into luminous energy; More existing incandescent lamp, gas discharge lamps have plurality of advantages such as principle of luminosity advanced person, no mercury pollution, along with improving constantly of technology, technological level; Just progressively replace the conventional light source scheme with LED as the illumination scheme of light source in growing field, still, because luminescence process is not only arranged during LED work; Also be attended by a large amount of heating processes, and the generation of these heat energy is huge or even fatal to the influence of LED illuminating product; Especially all the more so for high brightness, high power applications, so heat dissipation design is emphasis and the difficult point in the LED application scheme; Existing radiator is made up of heat-radiating substrate and the heat radiating fin that is arranged in parallel within the number of plate-shaped on the heat-radiating substrate, and heat-radiating substrate absorbs heat and is delivered to heat radiating fin, and dependence radiator radiations heat energy towards periphery dispels the heat; This radiator causes the heat alluvial easily; Radiating effect is bad, and structure is single, and is poor for applicability.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of novel structure is provided, and the better cartridge type wind-cooling heat dissipating of radiating effect device.
The utility model adopts following technical scheme to realize: cartridge type wind-cooling heat dissipating device; Include cooling base, be formed with heat radiating fin in a side of cooling base, said cooling base is surrounded by capping that offers the wind hole and base plate and constitutes; Cooling base forms the box like structure that has internal cavity; Have radiator fan to be placed in the internal cavity, the wind hole in the capping is made up of some circular holes, and said circular hole is arranged in the capping according to several concentric circles positions that radius increases gradually; It is cylindric that heat radiating fin becomes, the capping end face of arranging of several diameter different radiating fin nested, concentric.
Further technical scheme is, the height of said heat radiating fin has nothing in common with each other, and is outside by the center, and the height of heat radiating fin reduces gradually.
Adopt the cartridge type wind-cooling heat dissipating device of this structure, its heat radiating fin is high, not only rational in infrastructure to the labor aptitude of radiator fan, heat dispersion is excellent, and shape is novel, can adapt to more application demands.
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection domain of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model;
Fig. 2 is the blast structural representation of the utility model;
Fig. 3 is another blast structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
To shown in Figure 3, this cartridge type wind-cooling heat dissipating device includes by capping 2 and base plate 3 and surrounds the cooling base that constitutes, and is formed with heat radiating fin 1 in the top side of cooling base like Fig. 1; Offer the circular port 7 that serves as the wind hole on the base plate 3; Offer the circular hole 6 that serves as the wind hole in the capping, circular hole 6 is arranged in the capping 2 according to several concentric circles positions that radius increases gradually, and is outside by the center at the capping end face; In the capping 2 of arranging of six cylindric heat radiating fins 1 according to from high in the end order nested, concentric; And the two-layer heat radiating fin of outermost 1 is outward-dipping, and capping 2 surrounds out internal cavity 4 with base plate 3, and radiator fan 5 is arranged in internal cavity 4.

Claims (2)

1. cartridge type wind-cooling heat dissipating device; Include cooling base, be formed with heat radiating fin (1) in a side of cooling base, said cooling base surrounds formation by capping that offers the wind hole (2) and base plate (3); Formation has the box like structure of internal cavity (4); Have radiator fan (5) to be placed in the internal cavity (4), it is characterized in that: the wind hole in the capping (2) is made up of some circular holes (6), and several concentric circles positions that said circular hole (6) increases according to radius gradually are arranged in the capping (2); It is cylindric that heat radiating fin (1) becomes, the capping of arranging (2) end face of several diameter different radiating fin (1) nested, concentric.
