Description

Technical Field

[0001] This application relates to liquid cooling heat dissipation devices, and more particularly to a liquid cooling heat dissipation device that protects the water cooling radiator by means of a fan housing. Background Technology

[0002] In existing technology, water-cooled radiators (water cooling radiators) are usually equipped with fans to improve heat dissipation efficiency. When the fan is running, airflow passes through the blades and enters the cooling fins of the water cooling radiator to exchange heat and remove it. However, the fan is usually attached to one side of the water cooling radiator, making that side of the radiator generally exposed, which can easily lead to accidental contact and damage to the cooling fins or injury to the user.

[0003] In view of this, I have devoted myself to studying the existing technology and applying the relevant theories to try my best to solve the problems mentioned above, which has become my goal for improvement. Utility Model Content
