Heat sink fin structure

This creation is about a heat sink fin structure, especially a heat sink fin structure suitable for a heat dissipation module with high heat dissipation performance.

Cloud computing is a computing operation that uses a network to communicate multiple servers. It automatically splits a large number of computing programs into a myriad of smaller subroutines through the Internet, and then is composed of multiple cloud servers. The huge system, through the search and operation analysis, passes the processing result back to the user to achieve high-performance network services. The server that performs such calculation is called the cloud server.

With the advancement of technology, devices such as smart phones and satellite navigation (GPs) are all implemented through cloud computing, while the demand for cloud servers is increasing, and the server computing performance and hardware configuration density are relatively increased. The CPU (CPU) generates heat during the operation. For the high heat generated by the high watt processor, the heat dissipation performance will directly affect the operation of the server. Taking the standard size of the heat dissipation module as an example, since the size is limited in the width and height, if the conventional fin is directly added to the standard size, the gap between the fins is reduced to reduce the heat dissipation. It is not possible to directly increase the conventional fins to achieve better heat dissipation.

For the above reasons, the purpose of this creation is to provide a suitable for high dispersion. The heat-dissipating fin structure on the heat-dissipating heat-dissipating module effectively utilizes the fin beveling process to increase the throughput of the cold air and the total number of fins of the heat-dissipating module to improve the heat-dissipating efficiency of the heat-dissipating module.

In order to achieve the aforementioned objectives, the present invention provides a high heat dissipation performance. The heat dissipation fin structure on the heat dissipation module includes: a body having: a fixed surface, an air outlet end, a windward end, a cutting surface, and a cutting line. The fixing surface is located at the bottom in the height direction of the body. The outlet end is located at one end of the longitudinal direction of the body, wherein the width of the outlet end is the same as the width of the fixed surface; the windward end is the other end of the length direction of the body, and the wind is opposite to the wind end, and the wind is facing The width of the top end is thinner than the width of the wind end and the width of the fixed surface, and the width of the bottom of the windward end is the same as the width of the fixed surface; the body has at least one cutting surface, and the cutting surface is located in the width direction of the body. One side of the side; wherein the width of the fixing surface has a uniform width from the wind end to the windward end.

According to a first embodiment of the present creation, the body has at least one cutting line. It is located at a tangent to one side of the width direction of the body intersecting the cutting surface, and the cutting line is cut from the top of the outlet end to the bottom of the windward end.

According to a first embodiment of the present creation, the body has two cutting faces and two cutting lines.
