Heat dissipation device

The utility model provides heat dissipation equipment. The heat dissipation equipment comprises a sensor, a controller, a relay and a fan, the sensor is arranged in the heat dissipation equipment, isconnected with the controller, and is used for measuring the temperature of the tested equipment and transmitting a measurement result to the controller; and the controller is connected with the relayand is used for adjusting the resistance of the relay according to the received temperature data so as to control the rotating speed of the fan. According to the utility model, the problem of low heat dissipation efficiency caused by the fact that the heat dissipater rotates at a constant rotating speed once being started in the prior art is solved. 本实用新型提供了一种散热设备，包括：传感器，控制器，继电器和风扇；所述传感器内置在所述散热设备中，与所述控制器连接，用于测量被测设备的温度，并将测量结果传输到所述控制器；所述控制器，与所述继电器连接，用于根据接收到的温度数据调节所述继电器的电阻以控制所述风扇的转速。通过本实用新型，解决了相关技术中散热器一旦启动就会以恒定的转速进行转达导致散热效率低的问题。
