Description

Fin ring heat sink

technical field

The utility model relates to a heat sink, in particular to a heat dissipation device which can solve the problem of heat generated by electronic heating components such as CPUs.

Background technique

In order to solve the heat dissipation problem of high-heat-generating electronic components such as the central processing unit (CPU) of a computer, the heat pipe has become one of the indispensable components of the current heat dissipation device. In addition, in order to make the fins on the cooling device have a good distribution and cooperation with the air volume provided by the fan, the fin ring is also arranged on a cylindrical heat conduction seat, just like China Taiwan Announcement No. 575154 "Heat pipe heat dissipation The new type patent case of "device".

The new patent discloses a heat pipe cooling device, which includes a flat base, a cylindrical heat conduction cylinder with openings at both ends, a plurality of heat pipes and a plurality of heat dissipation fins, wherein the heat conduction cylinder is placed horizontally on the base And integrated with it, while the heat pipe passes through the base horizontally and is combined on the wall of the heat conduction cylinder in a loop shape. The fins are radially distributed inside the heat conduction cylinder for contact, and a fan can be installed inside the heat conduction cylinder. So that the fan can play the best heat dissipation effect.

However, although the above-mentioned heat pipe cooling device can produce good distribution and cooperation with the air volume provided by the fan, it ignores that the contact area between the heat pipe and the fins is too small to effectively exert the heat transfer effect of each heat pipe. Because the heat pipe cooling device not only uses the heat conduction cylinder as the heat conduction medium between the heat pipe and the fins, the heat energy cannot be directly transferred to the fins, which affects the heat transfer effect, and at the same time, each heat pipe is in contact with the heat conduction cylinder and is flat. , and only a single flat surface is in contact with the heat conduction tube, while the opposite flat surface is not connected with any fins or heat dissipation structure, so the contact area of the heat pipe at the condensing part and the heat dissipation structure is small, and it is difficult to The heat conducted by it is driven away as quickly as possible, so that the working fluid in the heat pipe cannot be quickly condensed and returned to a liquid state, and the heat exchange phenomenon cannot be carried out smoothly.

In view of this, the present inventor intends to improve and solve the above-mentioned shortcomings. Naite devoted himself to research and combined with the application of theories, and finally proposed a utility model with a reasonable design and effectively improved the above-mentioned shortcomings.
