Description

Technical Field

[0001] The invention belongs to the technical field of heat pipe heat dissipation, and in particular relates to a heat pipe radiator with an air guiding function. Background Art

[0002] With the increasing miniaturization and high performance of electronic devices, heat dissipation issues have received more and more attention. In order to cope with the heat dissipation challenges brought about by high power density, various radiators have come into being. Among them, heat pipe radiators are widely used due to their efficient thermal conductivity characteristics; the working principle of heat pipe radiators is based on the phase change principle of heat pipes, and heat is transferred by the vapor-liquid phase change of the working fluid in a fully enclosed vacuum tube. The heat pipe is filled with a low-boiling-point liquid. When one end of the heat pipe is heated, the liquid quickly evaporates into steam, and the steam flows to the other end under a small pressure difference, and condenses into liquid after releasing heat. The liquid then flows back to the evaporation section along the porous material by capillary force, and the cycle continues, and heat is continuously conducted from one end of the heat pipe to the other end.

[0003] The existing announcement number "CN221203139U" discloses a heat pipe radiator with an air guiding function, including a box body and an air inlet, a base is installed in the box body, and a plurality of heat sinks are installed on the base, the air inlet is fixedly installed on one side of the box body, and a handle is movably installed on one side of the air inlet, one end of the handle is fixedly connected to a transmission block, and the two ends of the transmission block are respectively connected to a first transmission frame and a second transmission frame, a first guide plate is fixedly installed on one end of the first transmission frame, and a second guide plate is fixedly installed on one end of the second transmission frame, and an air outlet is fixedly installed on one side of the box body. This device changes the direction of cooling air entering the box body by adjusting the inclination angles of the first guide plate and the second guide plate, thereby realizing the function of adjusting the heat dissipation position of the heat sink, thereby improving the practicability of the device.

[0004] The above-mentioned prior art solutions have the following defects: in actual use, after manually adjusting the guide plate, the wind direction is usually fixed, and it is unable to adapt to the changes in heat dissipation requirements caused by changes in environmental conditions (such as temperature, wind speed, etc.) during the use of the equipment. At this time, some heat sinks may not be able to fully dissipate heat due to uneven airflow, resulting in a decrease in the heat dissipation effect. In addition, manually adjusting the position of the guide plate to optimize the heat dissipation efficiency is not only time-consuming and labor-intensive, but also not efficient enough. It is difficult for users to make frequent adjustments during actual use, especially when the equipment load fluctuates greatly. The effect of manually adjusting the guide plate may not respond in time, resulting in fluctuations in the operating temperature of the equipment, affecting the stability and service life of the equipment. Summary of the invention
