[0002] CPU is one of the main devices of electronic computers. Its function is mainly to interpret computer instructions and process data in computer software. CPU appeared in the era of large-scale integrated circuits. The iterative update of processor architecture design and the continuous improvement of integrated circuit technology have prompted its Continuous development and improvement CPU has been developing rapidly since its birth. Currently, there are many types of radiators for desktop computer CPUs, and the technology is constantly maturing. There are self-cooling radiators, air-cooling radiators, water-cooling radiators, semiconductor radiators and heat pipe radiators. , as the heat sink continues to mature, with the development of electronic technology, the volume of electronic components is getting smaller and smaller, and the electronic assembly technology is also developing, making its integration density higher and higher, and the heat density it generates is also increasing , so the heat dissipation capacity of the radiator is extremely high. At present, air-cooled radiators and water-cooled radiators are mostly used in the market, but the structures of air-cooled radiators and water-cooled radiators are complex and inconvenient to use.

[0003] Currently authorized in China on April 1, 2007, the pulsating heat pipe radiator for electronic cooling with the authorized public number CN1946276A provides a new solution based on the above problems. It is equipped with cooling fins, pulsating heat pipes and a heat dissipation base. , easy to use, and convenient to dissipate heat, but the patent still has the following problems during use: the outside of the heat dissipation base lacks a good connection structure, and the heat dissipation base is connected with electronic components such as the CPU by adhesive bonding, which is inconvenient to install and disassemble; the pulsating heat pipe It is integrally formed by welding and is set in a serpentine circuit. The heat loss of the pulsating heat pipe is relatively slow, the heat dissipation time is relatively long, and the installation of the pulsating heat pipe is inconvenient.
