Laminated cooling structure

Abstract

An overlapped heat radiation structure comprises a bearing abutment, a supporting assembly, an overlapped assembly and a guide plate. The bearing abutment is provided with an installing surface. The supporting assembly comprises a supporting rod, a buffering ring and a locking ring, the supporting rod is arranged on the installing surface and sleeved with the buffering ring and the locking ring, the locking ring and the supporting rod are in threaded connection, and the locking ring abuts against the side surface, far away from the bearing abutment, of the buffering ring. The overlapped assembly is arranged on the installing surface and clamped between the buffering ring and the bearing abutment. The overlapped assembly is provided with a receding groove, and the supporting rod is located in the receding groove. The overlapped assembly comprises a plurality of overlapped plates which are overlapped. The guide plate is arranged on the installing surface and located in the receding groove, and the guide plate abuts against the inner side wall of the receding groove. In this way, different heat radiation loads can be adjusted correspondingly by adjusting the number of the overlapped plates of the overlapped assembly. In addition, the overlapped assembly is clamped between the buffering ring and the bearing abutment, and the overall structure stability is higher.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a stacked heat dissipation structure. Background technique [0002] Luminaires refer to appliances that can transmit light, distribute and change the light distribution of the light source, including all parts required to fix and protect the light source except the light source, as well as the necessary line accessories for connection to the power supply. Generally, in order to dissipate heat from the lamps and ensure the normal use of the lamps, the Radiator is used for the heat generated by the lamps when the lamps are working, so that the lamps can dissipate heat and cool to increase the service life of the lamps and ensure normal working performance. Therefore, the quality of the bearing base directly affects the life and normal working performance of the lamp. [0003] Generally, the heat dissipation load of the existing lamps is fixed, that is, the heat dissipation load...

AI Technical Summary

Problems solved by technology

[0003] Generally, the heat dissipation load of the existing lamps is fixed, that is, the heat dissipation load borne by the components that undertake the heat dissipation function in the lamps is fixed. However, when the lamp needs to install a lamp group or increase the power of the lamp group, it will inevitably cause The heat dissipation demand of the lamp is greatly increased. If the heat dissipation load borne by the components responsible for the heat dissipation function is fixed and cannot be changed, the heat dissipation performance of the lamp will be affected.

[0004] In particular, the overall structural stability of the parts that undertake the heat dissipation function of the existing lamps is relatively low
