Description

Heat abstractor

Technical field

The utility model is a kind of heat abstractor, and is particularly a kind of by the buckle mode of working in coordination, and makes integrated first and second parts be combined into one and is the radiator of stereo structure, and save the activity duration of fixing welding and the heat abstractor that reaches best insulation effect.

Background technology

The light source of normal contact has old-fashioned bulb in daily life, quartz bulb, fluorescent bulb and mercury vapor lamp etc., be different from aforesaid lamp source, light emitting diode belongs to chemiluminescence, it is low to have power consumption, component life is long, need not warm up the lamp time, advantages such as reaction speed is fast, it is little to add its volume, vibration resistance, be fit to volume production, demand on the fit applications is made easily, so light emitting diode (LED) has become critical elements indispensable in the daily life, but with light emitting diode as illuminating light source, because of electrical-optical conversion efficiency problem, can produce high heat during use, and the high heat that continues can cause damage for electronic component.

Now generally as illuminating led lamp, it mostly is provided with radiating seat, this radiating seat one side is provided with the radiating fin of a plurality of marshallings, those radiating fins and radiating seat are vertical configuration, and this radiating seat is provided with a recessed frame, be fixed with at least one lamp socket respectively on this recessed frame, those lamp sockets electrically connect with circuit board respectively, and be separately installed with a light emitting diode on those lamp sockets, thus, though can the hot type that circuit board produced be removed by radiating seat, and make the light emitting diode running normal, because of it is to concentrate on the circuit board, and only see through that a radiating seat dispels the heat, tend to take place heat retention on circuit board, can't rapidly thermal conductance be shed and situation that light fixture is scalded excessively, very undesirable in the use.

Moreover, please refer to shown in Figure 1, it is a kind of radiator of using as LED heat radiating 100, this radiator 100 is provided with a base 110, the floor 120 of lining up ring-type in the snapping mode is housed on this base 110, those floors 120 are as the usefulness of fin, and those floors 120 are expanded to the top gradually by the bottom, be provided with a ring 130 in those floor 120 top outer race, this ring 130 combines with welding manner and those floors 120, and ring has installed a disk body 140 in those floor 120 tops, and this disk body also is provided with the opposite disk body of opening direction 140 for 140 times, supplies to put light emitting diode and circuit board (not shown) in those disk bodies 140 respectively; During use, earlier this entire heat dissipation body 100 is handled through anode,, again those upper and lower disk bodies 140 are fixed in the interior ring of those floors 120 by welding manner so that this radiator 100 forms state of insulation; But thus, usually cause entire heat dissipation body 100 to have the on-insulated situation of part easily and cause user's danger, the fraction defective that also therefore produces this radiator 100 is too high, so that increases production cost, and is very undesirable in the use.

The utility model content

Main purpose of the present utility model is to provide a kind of heat abstractor in view of above-mentioned shortcoming, when combination, not only can save weld job, and increase the insulation effect of this heat abstractor, and can reach the purpose of rapid heat radiation.

A kind of heat abstractor that the utility model provides, it is mainly a kind of heat abstractor that is applied on light emitting diode (LED) light fixture, and this heat abstractor includes:

One first parts, it is made by heat-conducting and has heat-conducting effect, these first parts its for being integrated stereo structure, and these first parts are provided with first fastener;

One second parts, itself and first parts are worked in coordination, and these second parts also are integrated stereo structure, and these second parts are provided with second fastener that cooperates with first fastener;

During combination, can first and second parts be combined, thus, can save the activity duration of fixing welding and reach best insulation effect by the mutual buckle of first and second fastener.

A purpose more of the present utility model is to provide a kind of heat abstractor, is folded with between its first and second parts to have a heat conducting element at least, and this heat conducting element is good tablet that material constituted or a net of thermal conductivity, to increase radiating effect.

Another purpose of the present utility model is to provide a kind of heat abstractor, and the inner edge of its heat conducting element and second parts joins, to increase radiating effect.

Another purpose of the present utility model is to provide a kind of heat abstractor, can cooperate the overlapping heat conducting element that is folded with the unequal number amount of light emitting diode (LED) light fixture of different luminous powers between its first and second parts, to increase radiating effect.

According to such scheme, the utility model is significant with respect to the effect of prior art: on the heat abstractor that is provided as illuminating light emitting diode (LED) light fixture that the utility model provides, be provided with work in coordination first, two parts, this is first years old, two parts are respectively integrated stereo structure, and first, be respectively equipped with on two parts work in coordination first, two fasteners, when combination, can be by first, the mutual buckle of two fasteners, make first, two parts combine, thus, not only can save weld job and increase the insulation effect of this heat abstractor, and can reach the purpose of rapid heat radiation.
