Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to an internal toothed radiator and its heat dissipation system. Background Technology

[0002] With the continuous development of science and technology and industry, humans have invented many machines and devices to help them work or live. Most of these devices require energy to provide power. During use, it is inevitable that some of this energy will be converted into heat. Excessive temperature will affect the use of these devices and may even cause damage. Furthermore, if the heat cannot be dissipated in time, it may also damage the internal components of the device, leading to malfunction or instability. Currently, heat dissipation methods include adding cooling fans to the outside of the device or installing cooling fans or water cooling mechanisms on the components that generate heat inside the device. Due to the characteristics of the device and the limitations of the environment, some devices are used to increase the heat dissipation area to reduce or stabilize the temperature of the device.

[0003] Typically, finned heat sinks are used for cooling high-power IGBTs, especially in rectifiers and inverters, and are widely used in photovoltaic, wind power and other new energy sources, motors, water pump drives, and other applications. The fins are cut into standard spacing and with a certain thickness and height using a special finning machine. However, the existing finned heat sinks have poor structural design. The fins are exposed, making them prone to contact with other objects during transportation or use due to vibration, which can cause damage. This results in poor heat dissipation efficiency, poor stability, and limited applicability of the finned heat sink.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

This meets the connection and layout requirements between the workpiece position and the auxiliary heat dissipation device on different equipment, resulting in excellent usability.
