Description

Technical Field

[0001] The utility model relates to the technical field of improvements for facilitating cooling, ventilation or heating, and particularly relates to a high-strength aluminum profile heat sink. Background Art

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multi-sheets, etc. Its function is to conduct the heat generated by the components to the heat sink and then dissipate it into the surrounding air.

[0003] The heat dissipation fins on the high-strength aluminum profile heat sink are an important part of the heat sink. The heat dissipation fins are responsible for heat dissipation. However, the strength of the heat dissipation fins themselves is not high, and most of the current heat dissipation fins are fixedly connected to the heat conduction platform. When impacted by external objects, the heat dissipation fins are very easy to bend and deform. Once bent, it will affect the heat dissipation effect of the entire heat dissipation device. At the same time, some heat dissipation fins will be damaged due to certain reasons, and then the heat dissipation effect of these heat dissipation fins will also decrease. In order to ensure the heat dissipation effect of the heat sink, the entire heat sink needs to be replaced, which increases the maintenance cost of the heat sink. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a high-strength aluminum profile heat sink, which has the function of connecting the heat dissipation fins to the heat conduction platform by means of clamping. Thus, when some heat dissipation fins are damaged, only these heat dissipation fins need to be replaced, and there is no need to replace the entire heat sink, thereby reducing the maintenance cost of the heat sink.

The connection structures of the two clamping mechanisms are the same and are arranged symmetrically front and back. The baffle is connected to the fixing blocks through the two clamping mechanisms;

[0010] The clamping mechanism includes a limit block groove, a limit block, a first clamping groove, a sliding groove, a clamping block, a spring, a second clamping groove, a control groove and a control rod.

[0011] Preferably, the limit block groove is opened on the upper side of the fixed block, the rear wall of the limit block groove extends out of the fixed block, and the limit block is fixedly connected to the front side of the baffle.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a high-strength aluminum profile heat sink, which has the following beneficial effects:

[0018] (1) For this high-strength aluminum profile heat sink, when pulling the control rod to the left, after transmission, the clamping block will no longer be adapted to the first clamping groove and the second clamping groove to form a clamp. Then, in the same way, the clamping state of the rear clamping mechanism is also released. Then, the baffle can be removed, and then the damaged heat dissipation fins can be removed from the heat conduction platform for replacement. After the replacement is completed, the installation can be completed according to the above method. In this way, the heat dissipation fins can be connected to the heat conduction platform by clamping. Therefore, when a part of the heat dissipation fins are damaged, only these heat dissipation fins need to be replaced, and the whole heat sink does not need to be replaced, thus reducing the maintenance cost of the heat sink.

[0019] (2) For this high-strength aluminum profile heat sink, the spring will push the clamping block to move to the right, so that the clamping block moves into the second clamping groove, and then the clamping block forms a clamp with the first clamping groove and the second clamping groove, and the clamping state will not be released during the working process, thus improving the stability of the clamping mechanism during operation.
