Specifically, as shown in fig. 2, in the present embodiment, the housing 1 is provided with accommodating grooves 7 on the upper side wall, the lower side wall, the left side wall and the right side wall; the sliding block is a limiting protrusion extending along the length direction of the side plate 2, and in other embodiments, the sliding block may also be a T-shaped structure, which is not limited herein; each accommodating groove 7 is detachably provided with an air cooling plate 4.

In this embodiment, the air-cooled heat dissipation plate is connected with the accommodating groove 7 through a connecting piece, in order to enhance convenience and stability of installing the air-cooled heat dissipation plate 4, an installation hole with internal threads is arranged at the bottom of the accommodating groove 7, and a connecting hole corresponding to the installation hole is arranged on the air-cooled heat dissipation plate 4, and the installation hole and the connecting hole are in threaded installation connection through the connecting piece. The connecting piece is specifically a screw 6, and the air cooling plate 4 can be easily installed and replaced through the screw 6. The connecting hole is specifically a countersunk hole 9, when the screw 6 is screwed down, the nut end of the screw 6 is just embedded into the countersunk hole 9, and the outer side wall of the air-cooled heat dissipation plate 4 is relatively flat.
