Retractable Thermal Assemblies

Abstract

The invention discloses a storage type heat dissipation assembly. The storage type heat dissipation assembly comprises a bearing base, an installing table and a heat dissipation unfolded assembly; the two ends of the installing table are provided with a small-diameter end and a large-diameter end respectively, and multiple storage grooves are formed in the edge of the large-diameter end; the heat dissipation unfolded assembly comprises multiple heat dissipation unfolded parts, and the heat dissipation unfolded parts are arranged in the storage grooves in a one-to-one correspondence mode; each heat dissipation unfolded part comprises a heat dissipation unfolded sheet and a rotating shaft, wherein the rotating shaft is fixed to the inner side wall of the corresponding storage groove, the heat dissipation unfolded sheet is provided with a rotating hole, and the rotating shaft is rotatably arranged in the rotating hole in a penetrating mode. In the packaging and transporting process, the heat dissipation unfolded sheets are contained in the storage grooves, therefore, the surface of the overall structure is smoother, fewer protrusive structure exists, and limitation for packaging operation is lower; when the storage type heat dissipation assembly needs to be used, the heat dissipation unfolded sheets are exposed out of the storage grooves, therefore, the heat dissipation area is increased, the heat radiation and heat convection heat dissipation effect can be improved, and the heat dissipation performance is better.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a retractable heat dissipation assembly. Background technique [0002] At present, a lamp refers to an appliance 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, and also need to install heat dissipation components to ensure proper cooling performance. [0003] However, in actual situations, in order to improve the heat dissipation performance of the heat dissipation component, especially in order to increase the heat dissipation surface area of ​​the heat dissipation component, usually, the heat dissipation component will be provided with sheet-shaped, prismatic, column-shaped or / and dot-shaped and other structures used to increase the heat dissipation surface area, alth...

Problems solved by technology

[0003] However, in actual situations, in order to improve the heat dissipation performance of the heat dissipation component, especially in order to increase the heat dissipation surface area of ​​the heat dissipation component, usually, the heat dissipation component will be provided with sheet-shaped, prismatic, column-shaped or / and dot-shaped and other structures used to increase the heat dissipation surface area, although these structures can better improve the heat dissipation surface area of ​​the heat dissipation components, but due to these protruding structures, there are more discontinuous surfaces, that is, the overall surface is not smooth enough, and the , these protruding structures will generate large local stress on the packaging structure, which is easy to cause its own bending, and also easy to cause problems such as depressions in the corresponding areas of the packaging structure, and because the surface is not smooth enough, it will cost more packaging Material, that is to say, existing heat dissipation components due to the unevenness of the surface of the overall structure during packaging and transportation, thereby increasing the restrictions on packaging operations
