Heatsink with built-in fan

Abstract

The invention relates to a radiator with a built-in fan. The radiator comprises a radiating base, a radiating fin module and the fan, wherein a plurality of slots the periphery at intervals, surrounding the periphery of an inner end face of the radiating base are arranged for a plurality of radiating fins of the radiating fin module to be inserted respectively in a matching manner; the slots are subjected to extrusion deformation through stamping so that the radiating fins are tightly bonded on the radiating base; besides, the built-in fan is configured and bonded in the radiating fin module; when the radiating base absorbs the heat, the fan can be started to rapidly exhaust heat and temperature, thus achieving the aim of rapid radiation; and more than one heat pipe can be configured and bonded between the radiating base and the radiating fin module to improve the radiation efficiency of the radiator.

Description

technical field [0001] The present invention relates to a radiator design, in particular to a radiator design with a built-in fan. Background technique [0002] Conventional heat sinks for electronic components to dissipate heat mainly consist of a heat dissipation base (aluminum or copper bottom) and a heat dissipation fin module, or combined with a fan to form a heat sink, or can also be configured Combining more than one heat pipe to improve heat dissipation efficiency, it uses the heat dissipation base to attach to the electronic components to absorb heat, so that the heat can be transferred through the heat dissipation fin module to achieve the purpose of heat dissipation, or through heat pipes or With the help of the fan, the task of rapid heat dissipation is completed.

Problems solved by technology

[0003] Such as the conventional cylindrical heat sink, it consists of a cylindrical body and a plurality of cooling fins, each cooling fin is integrally formed (or welded) and radially extended on the peripheral wall of the cylindrical body, The electronic component is attached to the bottom surface of the cylindrical body, so the heat can be transferred to the plurality of heat dissipation fins on the surrounding wall through the bottom surface of the body to achieve the purpose of heat dissipation; Therefore, the number of fins is limited, the distribution density is low, and the fins are quite thick, so the weight is heavy, not only the heat dissipation efficiency is not good, but the cost is also expensive

In addition, the conventional cylindrical radiator has a cylindrical peripheral wall, so an external fan can only be directly installed on the upper end of the body, and the fan cannot be installed inside the body, resulting in an even larger radiator.

[0004] At present, there is also a stamping method to clamp and combine the heat dissipation fins on the peripheral wall of the above-mentioned cylindrical body to solve the lack of integral molding of the heat dissipation fins. This conventional structure still needs to have a cylindrical body, and in the The peripheral wall of the cylindrical body is provided with a plurality of vertically adjacent clamping grooves for inserting the heat dissipation fins one by one, and then combined by stamping, so that the plurality of heat dissipation fins are combined with the cylindrical body in a radial direction, so the cylinder The cylindrical body is still an indispensable main component, but because the cylindrical body has accounted for a considerable proportion of the weight and consumables, it is impossible to reduce the overall weight, nor can it effectively save consumables and reduce costs
