Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of controller accessories, in particular to a controller shell with sealing and heat dissipation functions. BACKGROUND

[0002] In the use process of the controller, a large amount of heat will be generated by the electronic components inside. If the heat cannot be dissipated in time, it will cause the temperature of the components to be too high, thereby affecting the performance and service life of the controller. At the same time, in some harsh working environments, such as humid and dusty environments, the controller shell needs to have good sealing performance to prevent moisture, dust and other impurities from entering the shell and causing damage to the electronic components. However, the traditional controller shell often has difficulty in simultaneously considering both sealing and heat dissipation, two important functions. Some shells pursue good sealing performance by adopting a tightly fitted structure, but this hinders the dissipation of heat; while some shells that focus on heat dissipation have poor sealing performance and cannot effectively resist the intrusion of external impurities.

[0003] The related technology in the above considers that:

A plurality of ventilation and heat dissipation fins are arranged on the inner bottom wall of the lower shell and the inner wall of the upper shell. The ventilation and heat dissipation fins in the lower shell and the ventilation and heat dissipation fins in the upper shell abut each other to form an air duct. Ventilation openings and exhaust openings are respectively formed on the opposite two side walls of the lower shell. Strengthening ribs in an inclined structure are arranged between adjacent ventilation and heat dissipation fins. The upper end surface of the strengthening rib located in the lower shell is inclined towards the ventilation opening in the horizontal direction, and the upper end surface of the strengthening rib located in the upper shell is inclined towards the exhaust opening in the horizontal direction. The present application has the advantages of simple structure, good heat dissipation efficiency, effective prevention of overheating of the shell, good protection of the connecting wires, and strong practicality.
