AI Technical Summary

Technical Problem

Existing technologies have poor heat dissipation efficiency. Hot air forms turbulence inside the heat sink housing, affecting heat dissipation efficiency. Furthermore, the power supply is prone to damage due to overheating, posing a safety hazard.

Method used

Design a heat dissipation system for a heat dissipation pad, with air vents located on both sides of the heat dissipation pad. The exhaust direction of the fan is consistent with the intake direction to avoid turbulence. The power supply is located at the end away from the main exhaust vent to prevent hot air from affecting the power supply temperature. Guide strips and baffles are used to optimize the airflow structure, improving heat dissipation efficiency and safety.

Benefits of technology

It improves heat dissipation efficiency, extends the service life of the power supply and cooling system, enhances safety, and prevents the risk of power supply overheating and spontaneous combustion or explosion.

Abstract

The embodiment of the utility model discloses a heat dissipation system of a heat dissipation patch. The heat dissipation system comprises a shell, a power source and a heat dissipation assembly. Wherein the shell comprises an upper cover and a lower cover; the lower cover comprises a bottom wall and a side wall extending upwards from the bottom wall, a mounting opening is formed in the bottom wall, and a machine body cavity with an opening is defined by the bottom wall and the side wall; a circulation opening is formed in the shell, the upper cover covers the opening of the machine body cavity, another circulation opening is formed in one side of the shell, one circulation opening is used for air inlet, and the other circulation opening is used for air outlet; the heat dissipation assembly comprises a heat exchange sheet, a heat dissipation body and a heat dissipation fan, wherein the two end faces of the heat exchange sheet are provided with silicon-containing heat conduction paste. The heat exchange sheet is fixedly arranged in the mounting opening; one end surface of the heat dissipation main body is connected with the heat exchange sheet and is positioned in the machine body cavity; the power supply is arranged in the machine body cavity, is far away from one end of the circulation port for air outlet, and is electrically connected with the cooling fan and the heat exchange sheet respectively. According to the heat dissipation system, the two circulation openings are formed in different directions, so that turbulent flow is prevented from being generated during air outlet, and the heat dissipation efficiency is improved.
