Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a geophysical exploration electrical signal filter device. Background Technology

[0002] Geophysical signal filtering is a technique used to process electrical signals obtained from geophysical measurements. Its main purpose is to extract useful signal information from complex measurement data, suppress noise and interference, and ensure the accuracy and reliability of the data. Electrical signal filtering is a fundamental technique in electronics and signal processing, used to improve signal quality, suppress noise or interference, and ensure the clarity and accuracy of the signal.

[0003] However, traditional geophysical exploration electrical signal filtering devices usually lack dedicated heat dissipation mechanisms. Electronic components are prone to overheating during operation, leading to performance degradation or damage, affecting the accuracy of measurement results and the lifespan of the equipment. Furthermore, without filters or guide structures, dust and particles in the air can easily enter the equipment, increasing the risk of impurity deposition, which can easily interfere with electronic components and even cause short circuits or malfunctions.

Under the detection of a temperature sensor, the processing module automatically controls the number of small fans to be activated via a control base. In conjunction with the filter screen and guide plate, the device reduces the possibility of dust particles entering and allows the airflow to be directed more precisely to the heating components. This ensures that the heating components are not damaged by overheating, extends the service life and stability of the equipment, reduces the impact of impurities on electronic components, and improves the reliability and maintainability of the equipment.
