Abstract
The invention discloses a side draft type LED (light-emitting diode) heat radiator. A heat radiation base is in a box-shaped structure defined by an upper substrate (2) and a lower substrate (3), wherein an upward concave cavity (4) is formed in the center of the bottom surface of the upper substrate (2); the top of the concave cavity is provided with air holes; a heat radiation fan (7) is arranged in the concave cavity (4) of the upper substrate; a plurality of heat radiation fins (1) are formed on the upper side surface of the upper substrate; a plurality of rib pieces (6) are formed on the upper side surface of the lower substrate (3); the rib pieces (6) are uniformly arranged at the upper side of the lower substrate (3) in a circumferential manner; a sealing cover of the upper substrate (2) is arranged on the lower substrate (3); and a plurality of air inlets are formed at the side circumference of the heat radiation base. The side draft type LED heat radiator is especially applicable to an LED lamp made of traditional high-density light source plate structures, is simple in structure and favorable in heat radiation effect and facilitates the integration process.
Description
Technical field
The present invention relates to the LED field of light fittings, relate in particular to a kind of LED radiator of side air inlet structure.
Background technology
Light emitting diode is as a kind of new light sources, its basic principle of luminosity is to emit excess energy in the carrier recombination process in the semiconductor, cause photo emissions and electric energy is converted into luminous energy, more existing incandescent lamp, gas-discharge lamp etc., has the principle of luminosity advanced person, without plurality of advantages such as mercury pollution, the range of application expanding day, but, 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, as can not in time distributing performance and the life-span of possible serious harm LED illuminating product, so, heat dissipation design is the Focal point and difficult point in the LED application scheme, especially for high brightness, high power applications is all the more so, and traditional scheme dependence radiator towards periphery radiations heat energy dispels the heat, cause easily the heat alluvial, weak heat-dissipating, after occurred air-cooled, water-cooleds etc. are applicable to the heat abstractor of great power LED, but complex structure, have increased the integrated difficulty of light fixture.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of integrated, radiating effect is better, simple in structure, diode is installed side-suction type LED radiator without any restriction.
The present invention is realized by the following technical solutions: side-suction type LED radiator, include cooling base, top at cooling base is formed with radiating fin, cooling base is enclosed by upper substrate and infrabasal plate and forms box like structure, the bottom central part position of upper substrate is formed with cavity upwards, the cavity top offers the wind hole, there is radiator fan to be placed in the cavity of upper substrate, the upper side of upper substrate is formed with some radiating fins, the infrabasal plate upper side is formed with some muscle sheets, described muscle sheet circumferential evenly is arranged in the infrabasal plate upside, and upper substrate is sealed on the infrabasal plate, forms some air inlets in the side week of cooling base.
The further technical scheme of the present invention is: the upper side of described infrabasal plate raises up.
The present invention further technical scheme is: the muscle sheet on the described infrabasal plate only is distributed in the peripheral position of infrabasal plate upper side, crosses cavity at the middle position of infrabasal plate upside by the muscle sheet.
Adopt the side-suction type LED radiator of this structure, be particularly suitable for adopting the LED light fixture of traditional high intensity light source plate structure to use, owing to adopt the radiating airflow channels designs of side air intake, not only guaranteed radiating effect, and to the installation of diode without any restriction, utilize convex surface design and the muscle chip architecture of infrabasal plate, can make things convenient for, effectively make up the air inlet in cooling base side week, that whole radiator has is simple in structure, good heat dissipation effect, be convenient to integrated advantage.
Below in conjunction with drawings and Examples the present invention is further set forth.
Description of drawings
Fig. 1 is blast structural representation of the present invention;
Fig. 2 is the blast structural representation of another angle of the present invention.
The specific embodiment
Such as Fig. 1, shown in Figure 2, this side-suction type LED radiator is by upper substrate 2, infrabasal plate 3, and radiator fan 7 assembles, the bottom central part position of upper substrate 2 is formed with cavity 4 upwards, the cavity top offers wind hole 5, some radiating fins 1 are formed on the upper side of upper substrate, the upper side of infrabasal plate 3 is convex surface, article 18, muscle sheet 6 is evenly distributed on the periphery of the upper side of infrabasal plate 3, and reserve cavity 8 at middle position, upper substrate 2 is accommodated in the radiator fan 7 of the incorgruous structure of bilayer in the cavity 4, and be sealed on the infrabasal plate, each muscle sheet 6 fills up between upper substrate 2 and infrabasal plate 3 and is separated out air inlet.
