Description

TECHNICAL FIELD

[0001] The utility model relates to a radiator technical field, concretely relates to a solar flower radiator with directional air duct structure. BACKGROUND

[0002] The air-cooled heat dissipation mode occupies more than 90% of the market in the electronic product heat dissipation field with the advantages of simple system, low cost and light weight. The air-cooled heat dissipation is generally composed of a fan and a radiator. The fan is the driving part of air flow. The fan drives air to blow through the surface of the radiator at a high speed, so that the air and the surface of the radiator exchange heat by convection, the heat generated by the electronic device is transferred to the air, and the air is taken out of the equipment, so that the purpose of cooling or temperature control of the electronic device is realized.

[0003] The radiator is used to increase the heat dissipation area and reduce the heat flux density of the unit solid surface in contact with the air. The radiator is used with the fan to reduce the temperature of the electronic component. According to Newton's cooling formula Q=hAΔt, when the heat dissipation Q remains unchanged and the heat dissipation area A is a constant, the effective method to reduce the temperature difference Δt is to improve the convection heat transfer coefficient h. In engineering application, it is to improve the air flow rate through the heat dissipation fin as much as possible, and to increase the air flow. For the air-cooled heat dissipation module, the outflow or inflow of the fan through the radiator is as much as possible.

[0004] The traditional air-cooled solar flower heat dissipation module is composed of a fan (turbine fan or axial flow fan) and a solar flower radiator. The inflow (turbine fan) or outflow (axial flow fan) of the fan flows through the radiator, and carries the heat on the surface of the radiator by convection heat exchange. The traditional solar flower radiator is open around the fin. In this type of radiator, the air flows through the fin in the process of flowing through the fin, and is affected by the surrounding air pressure (the surrounding air pressure is constant). Usually, the air flows out of the fin along the length direction of the fin, so that the effective air flow through the fin is reduced, the convection heat transfer coefficient is reduced, and the temperature of the electronic component is increased.
