working principle:

An extended water-cooled heat pipe radiator of the present invention, as the name implies, expands the liquid cooling function on the basis of the heat pipe radiator, and involves two working modes as follows: air-cooled heat dissipation of the heat pipe and water-cooled heat dissipation. The heat dissipation effect of the heat pipe is equivalent to that of the conventional heat pipe radiator. The heat is directly added to the heat pipe water cooling seat 2 and the heat pipe 1 through the electronic device. Part of the heat is conducted to the heat dissipation fin assembly 4 through the efficient heat transfer of the heat pipe 1, and the heat is taken away by the forced air cooling of the fans 5 on both sides to realize the efficient heat transfer of the heat pipe under air cooling;

Secondly, the water cooling mode can be used when the electronic device has higher heat generation or has water circulation equipment. In the water cooling mode, you can choose not to use the fan to avoid the use of the fan and water cooling at the same time, which will cause greater vibration and affect the normal operation of the device. Similarly The heat is directly added to the heat pipe water cooling base 2 and the heat pipe 1 through the electronic device, and part of the heat is transferred to the water cooling fins and then to the atmosphere through the heat pipe. 2-3 is circulated to the external water-cooling machine to achieve good water-cooling heat dissipation effect.
