Abstract
The invention discloses a tube type heat radiator which comprises a heat radiation base and heat radiation fins (1), wherein the heat radiation base is defined by a lower substrate (4) provided with air holes (2) and an upper substrate (3) provided with heat radiation fins (1); the whole heat radiation base is in a box-shaped structure in which an inner cavity is formed between the upper substrate (3) and the lower substrate (4); a heat radiation fan (5) is arranged in the inner cavity; the heat radiation fins (1) are hollow cylindrical ones, and each heat radiation fin (1) is provided with a through hole (6) in the middle; the heat radiation fins (1) are arranged on the top surface of the upper substrate (3) at intervals; the air holes are arranged on the upper substrate (3) and are only corresponding to the heat radiation fins (1); and the air holes of the upper substrate are communicated with the through holes (6) of the heat radiation fins. According to the tube type heat radiator, the heat radiation structure is reasonable, the heat radiation effect is enhanced, the heat radiation action of the outer surface of the upper substrate is optimized, and the whole heat radiation performance is excellent.
Description
?
Technical field
The present invention relates to LED lamp radiator, relate in particular to a kind of tubular radiator with fan.
Background technology
Led light source has long service life, start-up time is short, energy-saving effect is remarkable, without ultra-violet radiation, can not bring mercury pollution, the plurality of advantages such as safety in utilization height, becoming gradually the main flow of lighting source, but, although the luminous efficiency of LED is in continuous improve, but heat generation in the course of the work still can't be avoided, especially for high-power, high-density applications, these heats can badly influence life-span and the performance of product, existing LED light fixture, main dependence heat radiation is dispelled the heat, heat dispersion is limited, the application needs that improve constantly in order to adapt to the heat radiation requirement, existing by fan being set to strengthen the device appearance of dissipation of heat, Chinese patent literature CN201401764Y discloses a kind of " with the high-power LED lamp structure of fan ", this high-power LED lamp structure with fan is characterised in that: be provided with fan, radiator is the tubular body that is provided with the hollow tube chamber, fan is fixed in the center of radiator tail end, though this successful fan being incorporated in the heat sink conception of LED of high-power LED lamp structure with fan, but on the one hand, its current path is unreasonable, and radiating effect has much room for improvement; On the other hand, this way of acquiring fan in the radiator outside causes fitting structure complicated, is not easy to the assembling production of light fixture, also is difficult to the reliability that guarantees that fan is installed.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of integrated, rational in infrastructure, the better embedded air-cooling heat-dissipating of radiating effect is provided.
The present invention is realized by the following technical solutions: tubular radiator, include cooling base and heat radiating fin, described cooling base is enclosed with the upper substrate that is provided with heat radiating fin by the infrabasal plate that offers the wind hole and forms, the whole box like structure that becomes between upper substrate and infrabasal plate, to be formed with internal cavity of cooling base, there is radiator fan to be placed in the internal cavity, described heat radiating fin is hollow tube-shape, the centre has through hole, the heat radiating fin interval is built up in the upper substrate end face, upper substrate and only offer the wind hole in position corresponding to heat radiating fin, the wind hole of upper substrate is communicated with the through hole of heat radiating fin.
Further technical scheme is, described heat radiating fin includes some groups of differing heights, highly different heat radiating fins arranging separately.
Further technical scheme is, the through hole of described heat radiating fin is lower large little taper pore.
Adopt the tubular radiator of this structure, not only fan and radiator are combined, form the standarized component of LED light fixture, and radiator structure is reasonable, by the radiating fin of tubular type, has not only increased area of dissipation, has improved gas channel, and strengthened air velocity, strengthened radiating effect by the taper pore design to the through hole of heat radiating fin, also by being intervally arranged of differing heights heat radiating fin, optimized the thermolysis of upper substrate outer surface, the integral heat sink excellent performance.
Below in conjunction with drawings and Examples the present invention is further set forth, protection scope of the present invention includes but are not limited to accompanying drawing and the disclosed content of embodiment.
Description of drawings
Fig. 1 is the blast structural representation of one embodiment of the invention;
Fig. 2 is the blast structural representation of another embodiment of the present invention.
The specific embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
Embodiment one: as shown in Figure 1, be provided with sidewall around the upper substrate 3 of this tubular radiator, the end face of upper substrate 3 is provided with heat radiating fin 1, described heat radiating fin 1 is hollow tube-shape, the centre has through hole 6, through hole 6 is lower large little taper pore, heat radiating fin 1 is applied on the upper substrate 3, the lower port of through hole 6 has namely been served as the wind hole of upper substrate, the remainder complete closed of upper substrate, evenly offer wind hole 2 on the infrabasal plate 4 of this tubular radiator, upper substrate 3 and infrabasal plate 4 enclose the formation cooling base, and two radiator fans 5 are placed in the cavity of cooling base.
Embodiment two: as shown in Figure 2, the difference of the tubular radiator of the present embodiment and embodiment one only is, heat radiating fin 1 includes three groups of two kinds of height, and one group the height that is positioned at central authorities is low, has two groups of high heat radiating fins 1 of height to be arranged in its both sides.
Embodiments of the present invention are not limited to above-described embodiment, all should belong within protection scope of the present invention not breaking away from the various variations that the present invention conceives under the prerequisite.
