Abstract

The utility model discloses a LED lamp circuit board heat abstractor, comprising a base plate, the bottom plate upper surface is equipped with the frame, the inside equal thermal dissipation baffle in interval that is equipped with of frame, thermal dissipation baffle is unified transverse arrangement, thermal dissipation baffle is per to be equipped with the pivot between two, the pivot both ends articulate on the frame, the pivot runs through the commentaries on classics leaf, be equipped with in the pivot and change the isometric rotation festival of leaf, through thermal dissipation baffle with change the leaf, increased heat radiating area and circulation of air speed, make the heat of LED lamp circuit board can better distributing away, simultaneously, change the leaf and flow the in -process at the air and can rotate because of air force, drive a plurality of commentariess on classics leaves simultaneously and rotate, will turn into kinetic energy because of the heat that the circuit board produced, the joining of having avoided power device makes the too big problem that can't the use of radiator volume.

Description

A kind of LED circuit plate heat dissipating device
Technical field
The utility model is related to heat abstractor technical field, specially a kind of LED circuit plate heat dissipating device.
Background technology
The basic structure of LED is one piece of electroluminescent chip of semiconductor material, with elargol or latex solidified on support, Then with silver wire or gold thread connection chip and circuit board, then surrounding epoxy sealing, plays the work of protection internal core With, shell is finally installed, so the anti-seismic performance of LED is good, with field the daily household electrical appliances such as mobile phone, desk lamp, household electrical appliances are related to With machinery production aspect, LED luminaire applications more and more extensively, but LED can also produce in use one Fixed heat, can to a certain extent affect the service behaviour of LED, therefore the heat dissipation problem of LED wiring board is to be solved Problem, due to the smaller problem of LED circuit plate bulk so as to large-scale heat dissipation equipment cannot be installed to be radiated, be this It is proposed that a kind of LED circuit plate heat dissipating device.
Utility model content
The purpose of this utility model is to provide a kind of LED circuit plate heat dissipating device, to solve above-mentioned background technology in The problem of proposition.
For achieving the above object, the utility model provides following technical scheme:A kind of LED circuit plate heat dissipating device, bag Base plate is included, the plate upper surface is provided with housing, the equal heat-dissipation spacer in interval, the heat-dissipation spacer are provided with inside the housing It is transversely arranged for unification, rotating shaft is provided between the heat-dissipation spacer each two, the rotating shaft two ends are hinged on housing, described turn Axle runs through rotating vane, and the rotating shaft is provided with the rotation section isometric with rotating vane.
Preferably, the quantity of the rotating vane is at least 2, and is contacted by rotating shaft.
Preferably, it is provided with slip ring between the rotating vane each two.
Preferably, ventilation interval is provided between the rotating vane and heat-dissipation spacer.
Compared with prior art, the beneficial effects of the utility model are:By heat-dissipation spacer and rotating vane, radiating surface is increased Product and air passage rates, the heat for enabling LED wiring board is preferably distributed, meanwhile, rotating vane is in air flow process In can be rotated because of air force, be kinetic energy by the converting heat produced because of wiring board while driving multiple rotating vanes to rotate, keep away The addition of power set is exempted from so that the excessive problem that cannot be used of radiator volume.
Description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the mounting means figure of the utility model rotating vane and rotating shaft;
Fig. 3 is the utility model A-A ' places unit cutaway view Amplified image.
In figure:1st, base plate, 2, rotating vane, 3, housing, 4, heat-dissipation spacer, 5, rotating shaft.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme:A kind of LED circuit plate heat dissipating device, including bottom Plate 1, for the carrier and pedestal that are arranged on whole device on LED wiring board, the upper surface of the base plate 1 is provided with housing 3, outward Frame 3 is square frame, for installing heat-dissipation spacer 4, the equal heat-dissipation spacer 4 in interval is provided with inside the housing 3, described to dissipate Hot dividing plate 4 is transversely arranged for unification, increases the area of dissipation of whole device, and between each two of the heat-dissipation spacer 4 rotating shaft is provided with 5, it is that rotating vane 2 is installed to provide basic mounting structure, the two ends of the rotating shaft 5 are hinged on housing 3, are to install rotating vane 2 to provide installation Space, the rotating shaft 5 runs through rotating vane 2, determines the operating position of rotating vane 2, while the initial installation site of rotating vane 2 is all horizontal State, the rotating shaft 5 is provided with the rotation section isometric with rotating vane 2, facilitates the work of rotating vane 2.
Specifically, the quantity of the rotating vane 2 is at least 2, and is contacted by rotating shaft 5, realizes the independence of each rotating vane 2 Operating, the power needed for reducing.
Specifically, slip ring is provided between each two of the rotating vane 2, reduces rubbing when independently rotating between each rotating vane 2 Wipe, the aerodynamic energy needed for reducing.
Specifically, ventilation interval, when air flow is weaker, Ke Yishi are provided between the rotating vane 2 and heat-dissipation spacer 4 The function of now radiating, it is to avoid rotating vane 2 does not turn the space-closed for causing.
Operation principle:When LED wiring board works, heat production point can heat the base plate 1 of current location, and base plate 1 is heated Partial air also can be heated, the expansion pressure increase of current location air, and hot-air is moved upwards, while taking away partial heat The rotation of rotating vane 2 is driven, cold air is brought into into from other side in rotation process, so circulation makes rotating vane 2 surround rotating shaft 5 Rotated, rotating vane 2 rotates the flowing velocity for increasing air, improved the efficiency that heat is taken away;Simultaneously heat-dissipation spacer 4 also can be the bottom of by The heat that plate 1 absorbs distributes a part, further improves the effect of radiating.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
