Abstract:
The present invention belongs to the technical field of wave recorders. Disclosed is a dustproof and heat-dissipation type wave recorder. The dustproof and heat-dissipation type wave recorder comprises a shell and an end cover, wherein a wave recording device is arranged in the shell. The shell comprises a bottom, wherein an edge of an upper surface of the bottom is provided with a frame which extends upwards to a preset height, and the top of the frame is provided with a dustproof connecting part used for installing the end cover. The end cover comprises a cover body, wherein an edge of a lower surface of the cover body is provided with a butt joint part matching the connecting part, and the connecting part and the butt joint part are assembled to form a sealed connection. According to the present invention, the sealed connection is formed by means of cross connection of the shell and the end cover, thereby improving the sealing performance of the joint; and a bolt connecting part is isolated by means of the sealed connection, so that the dustproof effect is further achieved. The shell is made ultra-thin, and the airflow of internal air during operation is increased by means of different hollowed-out structures, so that cooling treatment is achieved.
