Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, and in particular to a low-noise fan with energy-saving heat dissipation. Background Art

[0002] Cooling fans are mainly used for heat dissipation and cooling, and are widely used in computers, industrial equipment, home appliances and other fields. Cooling fans are divided into axial flow fans, centrifugal fans, mixed flow fans, cross-flow fans and the like. Among them, the blades of the axial flow fan push the air to flow in the same direction as the axis. The impeller of the axial flow fan is somewhat similar to a propeller. When it is working, most of the airflow flows parallel to the axis, in other words, along the axis. When the inlet airflow of the axial flow fan is free air with zero static pressure, its power consumption is the lowest. When it is running, the power consumption will increase as the back pressure of the airflow increases. Axial flow fans are usually installed on the cabinets of electrical equipment, and are sometimes integrated into the motor. Due to their compact structure, axial flow fans can save a lot of space and are easy to install, so they are widely used. In the existing technology, cooling fans still have the problems of high energy consumption and high noise. Utility Model Content

[0027] Referring to the accompanying drawings of the specification, in an embodiment of the present utility model, an energy-saving and heat-dissipating low-noise fan comprises a fan assembly 1 and a heat-conducting structure 2 connected to the fan assembly 1, wherein a mounting bracket 3 is connected to the bottom of the heat-conducting structure 2;

[0028] The fan assembly 1 includes a frame 101, on which a ventilation duct 104 is provided. Four groups of reinforcing ribs 105 are fixedly arranged in a circular array on the inner wall of the ventilation duct 104. The same motor mounting platform 107 is fixedly arranged at one end of the reinforcing ribs 105 close to each other. A fan motor 106 is fixedly installed in the motor mounting platform 107, and multiple groups of fan blades 108 are fixedly installed on the output shaft of the fan motor 106.

The ventilation duct 104 is opened along the axis of the mounting ring 103 and passes through the mounting plates 102 on both sides. The four corners of the mounting plate 102 are provided with mounting holes 109.

[0030] As a possible example, in this embodiment, the heat conduction structure 2 is made of pure copper with good thermal conductivity. The heat conduction structure 2 includes a heat sink fin group consisting of a plurality of parallel stacked heat sink fins 201 and a heat pipe 202 extending through the heat sink fin group. The bottom end of the heat sink fin group is fixedly connected to a copper base 203, which is provided with a threaded hole for connecting to the mounting bracket 3.

[0031] Specifically, in this embodiment, the heat pipes 202 are U-shaped as a whole and are arranged in four groups in a staggered manner. The upper surface of the copper bottom 203 is provided with grooves matching the heat pipes 202 .
