In order to preferably improve the mobility of the heat eliminating medium, the LED module is taken away to improve the heat eliminating medium The rate of the heat of generation, and then heat dissipation performance is improved, for example, the recirculation assembly includes the pump housing and power supply mould group, the electricity Source mould group and the pump housing are electrically connected, the pump housing respectively with the second end of the inflow hole and the circulating line second End connection;For another example, at least two tap holes, and at least two circulating lines of setting, each circulation are set The first end one-to-one correspondence of pipeline is connected to the second end of a tap hole, is produced when in this way, being worked normally using the pump housing Raw negative pressure can provide required power when heat eliminating medium flowing, continuously so as to preferably improve The mobility of the heat eliminating medium, to improve the rate that the heat eliminating medium takes away the heat that the LED module generates, Jin Erti High heat dispersion.For another example, the power supply mould group also with the LED module be electrically connected, for another example, the power supply mould group also with outside Power supply connection.For another example, the circulating line is additionally provided with communicating pipe, and the runner pipe is provided with valve, when the closing valve Men Shi, the communicating pipe closes, and when opening the valve, the communicating pipe is opened, for example, working as the liquid-cooling LED headlamp It, can be by the valve and the communicating pipe come to the liquid cooling when heat eliminating medium inside tool is needed replacing or supplemented Heat eliminating medium inside LED illumination lamp needs replacing or complement operation, shines so as to greatly extend the liquid-cooling LED The service life of bright lamp tool.
The circulation path of the circulation medium is as follows:
When not opening the recirculation assembly, the heat eliminating medium is in non-circulation device, i.e., the described heat eliminating medium is in institute Accommodating inside cavity is stated to remain static.
When opening the recirculation assembly, based on the negative pressure that the recirculation assembly generates, the heat eliminating medium is by the appearance One end that the installation tube body is entered to inside cavity 310 is set, i.e., the described heat eliminating medium inside the accommodating cavity 310 by entering To the second go side of the circulation cavity, after the circulation cavity for flowing through the installation tubular body, the inflow hole is entered to Inside flows into the circulation module internal by the inflow hole again later, then, flows out to the stream by the cyclic module group In portalling, and the circulation inside cavity is flowed out by the tap hole or flow back into, is followed in this way, the heat eliminating medium completes one Ring flow-through operation, in this way, heat eliminating medium can be during circulating, it can quickly, in time and continually area The heat generated when walking 500 normal luminous of LED module to avoid heat there is a phenomenon where accumulating, and then avoided thermogenetic Light decay, in this way, liquid-cooled and/or air-cooled heat dissipation effect can be played.
It should be noted that the LED module, in adstante febre, most heat can be transferred directly to the installation tube body On, and the heat eliminating medium of circulation can also be taken away described other than it can directly take away the heat that the LED module generates The heat being transmitted on installation inboard wall of tube body and outer wall by the LED module, in this way, can efficiently and in time take away The heat that LED module generates, and by these even heats be transferred in the entirety of the heat eliminating medium, it is situated between by the heat dissipation Matter plays liquid-cooled heat dissipation effect further by these heat losses into extraneous air.
In addition, the heat eliminating medium of circulation can also further increase venturi effect relative to static heat eliminating medium, That is flow-disturbing effect, in this way, can reduce to a certain extent the rotten of the heat eliminating medium or other by static the problem of bringing.
In order to further increase the heat dissipation performance of the installation tube body, for example, referring to Fig. 2, installation tube body 410 has spiral shell Shape structure is revolved, and the side wall of the installation tube body 410 offers several auxiliary exchange hole (not shown), several auxiliary are handed over It changes between hole and is provided with interval, in this way, the installation tube body of helical structure can greatly improve the installation of LED sub-light source Area, brightness and power higher lighting requirements more so as to meet quantity, and it is based on above structure, it can also be into One step improves the cooling surface area of the installation tube body, so as to take into account high power and the big requirement of quantity of heat production, and then can be with Further increase the heat dissipation performance of the installation tube body.
In order to further increase the heat dissipation performance of the installation tube body, for example, the installing pipe has distortion and/or bending Helical structure;For another example, there are the installation tube body several spires to connect to be formed, and each spire is additionally provided with auxiliary Communicating pipe, the auxiliary communication pipe are connected to the circulation cavity;For another example, the installation tube body has first end and second end, The internal diameter of the installation tube body is gradually increased by the first end to the second end;For another example, it is set on the installation tube body The quantity of the auxiliary exchange hole be gradually reduced by the first end to the second end;For another example, the auxiliary exchange hole Hole wall is obliquely installed, and the extending direction of the auxiliary exchange hole is arranged towards the second end, in this way, institute can further be increased The cooling surface area of installation tube body and the trafficability performance to heat eliminating medium are stated, and then can be further improved the installation tube body Heat dissipation performance.
It is appreciated that being dissipated described since the volume of the accommodating cavity is far longer than the volume of the circulation cavity Flow velocity of the thermal medium inside the lampshade is far longer than the flow velocity of the installation tubular body, therefore, in the installing pipe body The heat eliminating medium in portion is better than external heat dissipation effect to the transport effect of heat, i.e. heat dissipation effect, therefore, in order to further mention The heat dissipation performance of the high installation tubular body, for example, referring to Fig. 4, installation tube body 410 includes being sequentially overlapped setting first to dissipate The heat dissipation of thermally stratified layer 412, second layering 413 and third heat dissipation layering 414, the first heat dissipation layering are set towards the accommodating cavity It sets, the third heat dissipation layering is arranged towards the circulation cavity;For another example, it is described first heat dissipation layering, second heat dissipation layering and The identical setting of material phase exclusive or of third heat dissipation layering;For another example, the first heat dissipation layering, the second heat dissipation layering and third heat dissipation The thickness of layering successively successively decreases;For another example, the installation tube body has distortion, spiral or/and warp architecture;For another example, described first Heat dissipation layering opens up fluted far from the side of the second heat dissipation layering, and the installation position is formed on the bottom of the groove;Again Such as, it is provided with mounting jaw at the marginal position of the installation position, in this way, can be further improved dissipating for the installation tubular body Hot property.
