DETAILED DESCRIPTION

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the model of the controller, the model of the temperature sensor, how the controller cooperates with the temperature sensor, the model of the cylinder 11, how the controller controls the cylinder 11, the model of the cooling fan group 8, how the controller controls the cooling fan group 8, the material of the heat dissipation fins, and the cooling principle of the heat dissipation fins, etc.

A sealing mechanism is installed inside the fixed cover 9. The housing 1 has several mounting areas 15 corresponding to the air outlets 10. Each mounting area 15 has a temperature sensor and heat dissipation fins, with the heat dissipation fins located between the air inlet channel 3 and the air outlet channel 7. The controller controls the sealing mechanism to close or open the air outlets 10 based on the data monitored by the temperature sensor.

[0025] Multiple installation areas 15 are configured, each equipped with a temperature sensor. When the temperature sensor in a particular installation area 15 detects excessively high temperatures requiring cooling, the controller precisely activates the cooling fan assembly 8 and simultaneously opens the corresponding air outlet 10 via the sealing mechanism. The air blown by the cooling fan assembly 8 is then concentrated through the opened air outlet 10 and precisely delivered to the cooling fins of that area for efficient cooling. This design avoids indiscriminate airflow across all areas, achieving on-demand cooling. Because the airflow from the cooling fan assembly 8 can be precisely delivered to the areas requiring cooling, it does not need to maintain high-speed operation, thus reducing the operating power of the cooling fan assembly 8 and lowering energy costs. Simultaneously, the reduced fan speed effectively reduces noise during operation, improving the user experience.
