Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the structural section schematic diagram of one embodiment of the utility model.
Specific embodiment
Below with reference to drawings and examples the utility model is described further, but this reality should not be limited with this
With novel protection scope.
As shown in Fig. 1, the utility model provides a kind of lamps and lanterns cooling cavities, the tubulose which extends along its length
Cavity, the section of the tubular housing include 9 part of outer wall section, middle partition 1 and cavity.
Wherein, outer wall section includes superposed fixing plate 4, the left and right two of the fixing plate 4 and outer wall section top
Side, upwardly extending the upper end of wall 5 from a pair of outer wall section, the horizontal axis to the length direction of cooling cavities prolongs respectively
It stretches.
The lower end that a pair upwardly extends wall 5 is connected by middle partition 1, and partition 1 connects a pair and upwardly extends wall 5 in this
Lower end and level extension.
The a pair of fixing plate 4, a pair upwardly extends wall 5 and middle partition 1 together constitutes a complete luminous component
Holding part.In use, high power LED device 7 is mounted on circuit board 6, by the circuit board 6 and great power LED device
The insertion a pair of the fixing of part 7 plate 4, a pair upwardly extends wall 5 and middle partition 1 together constitutes the appearance of a complete luminous component
Set portion.And the height that a pair upwardly extends wall 5 is 2-3mm bigger than the thickness of the circuit board 6, so that the circuit board 6 is in the appearance
Set has certain mobile surplus in above-below direction in portion.
A pair of outer wall section extends downwardly wall 2 and bottom plate 3 and middle partition 1 constitutes 9 part of cavity of a sealing.
This extends downwardly end vertical of the wall 2 therefrom at left and right sides of partition and extends downwardly, and in the lower end and bottom for extending downwardly wall 2
Plate 3 is attached.Preferably, it extends downwardly the lower end of wall 2 and the connection of bottom plate 3 is that fillet is connect, to reduce thermal cycle
Stress in the process is concentrated.
It can be filled with heat recipient fluid appropriate inside the hollow cavity 9, for example, air, inert gas or heat absorption liquid
Body.
Groove 8 is set in the middle position of bottom plate 3, which can be the continuous V-shaped in cavity length azimuth axis
The v type groove for the certain length that slot is either spaced apart in cavity length azimuth axis.
Material of partition 1 and outer wall section can choose as the heat radiating metal with certain elasticity, such as Cu, Al in this,
Or the alloy material of above-mentioned material.Its with a thickness of 3-5mm, the thickness guarantee certain mechanical strength to can reduce device whole
The weight of body, furthermore metal material has certain elasticity under above-mentioned thickness, can preferably realize the effect of the utility model
Fruit/
When high power LED device 7 and circuit board 6 are mounted on above-mentioned holding part, circuit board 6 is due to gravity
With the middle closely connection of partition 1, heat-conducting fluid export of the heat by partition 1 in this into cavity 9.The heat-conducting fluid and outer wall
After portions under heat, expansion can be generated, so that centering partition and outer wall section cause pressure P as shown in Figure 1, so that in
Partition 1 and bottom plate 3 protrude outward, since holding part remains the surplus on circuit plate thickness direction, even if middle partition 1
It projects upwards, the deformation of circuit board 6 will not be caused, and can be improved the closeness of contact of middle partition 1 and circuit board 6, into
One step improves heat dissipation effect.
Further, since the groove 8 on bottom plate 3 makes bottom plate 3 have bigger flexible deformation surplus, the production of stress is avoided
It is raw, protect cavity structure caused by cumulative stress in thermal cycle to destroy.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and is modified.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right
Some modifications and changes of the utility model should also be as falling into the protection scope of the claims of the present utility model.In addition, to the greatest extent
It is used some specific terms in pipe this specification, these terms are merely for convenience of description, not to the utility model
Constitute any restrictions.
