TECHNICAL FIELD
[0001] The utility model relates to a radiator technical field especially point to a radiator module of promoting heat dissipation effect. BACKGROUND
[0002] In modern electronic products, especially high-performance graphics cards, the design of the radiator is particularly important. This is because electronic devices generate a large amount of heat when they are working, especially in high-load operations such as graphics processing and complex computing tasks. The main reason for generating heat is the power consumption of the components. When current passes through semiconductor materials, resistance will cause part of the electrical energy to be converted into heat energy. If the heat cannot be dissipated in time, the temperature rise will cause the performance of the components to decline, and even damage.
[0003] Currently, the traditional cooling methods mainly include air cooling, liquid cooling and heat pipe cooling. Air cooling relies on fans to remove heat from the surface of electronic components, which is a widely used and cost-effective method, but it often has the problem of insufficient cooling efficiency in high-performance products; liquid cooling removes heat through liquid circulation, which is more efficient and has lower noise, but the structure is complex, the cost is high and leakage prevention measures are required; heat pipe cooling uses materials with good thermal conductivity to quickly transfer heat to the heat sink area, but it is limited by the upper limit of heat pipe design. Especially in high-performance graphics cards, as the computing power increases, the heat generated rapidly rises. If the cooling system cannot quickly reduce the temperature, the graphics card will reduce the frequency to protect itself, resulting in performance degradation.
[0004] For example: China patent authorized announcement number CN 101605442B's radiator, in the technical scheme disclosed in this patent, the radiator is mainly used for cooling the circuit board, the radiator includes a base, a radiator, a fan, and a cover. When working, the base and the circuit board are fixed to the circuit board by the fixing member, the bottom surface of the base can contact one or more electronic components, and the heat conduction effect can be enhanced by applying heat-conducting glue between the bottom surface of the base and the top surface of the electronic components. Insulating film can be placed between the radiator and the circuit board to provide insulation and cushioning. Since the heat pipe is a high-efficiency heat-conducting plate-shaped heat pipe, the heat generated by the electronic components can be absorbed by the heat pipe and quickly and evenly distributed throughout the heat pipe. The heat is conducted to the entire radiator, and finally the airflow generated by the fan passes through the airflow channel in the radiator to quickly remove the heat, thereby achieving the effect of quickly cooling the electronic components.
[0005] As described in the above patent, since the heat dissipation devices on the market are all using the airflow generated by the fan to blow through the heat sink or the heat conductor to take away the heat, the heat dissipation efficiency is largely dependent on the heat conductivity of the heat sink or the heat conductor, when the heat conductivity of the heat sink or the heat conductor is reduced due to dust accumulation or other reasons, the electronic components are prone to instantaneous high temperature, which leads to the performance degradation or damage of the electronic components, therefore, ensuring the continuous and stable heat dissipation of the electronic components is an important factor for maintaining the performance of the electronic products and improving the service life.
