[0004] However, existing DTU terminal devices rely on a single metal casing for heat dissipation, which has low heat dissipation efficiency and is prone to overheating, affecting the normal use of the DTU terminal device. Moreover, after the DTU terminal device is fixed on the wall, the back of the device is in close contact with the surface of the fixed object, and the connection is more prone to overheating, resulting in poor heat dissipation effect of the DTU terminal device. Therefore, it does not meet existing needs. In this regard, we have proposed a DTU terminal device with good heat dissipation effect. Utility Model Content

[0012] Preferably, the upper surface of the first mounting plate is provided with mounting holes, and the mounting holes include bolt holes and hanging holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model sets side heat dissipation components on both sides of the DTU main body, sets a lower heat dissipation component at the lower end of the DTU main body, and uses the height difference between the support frame and the DTU main body to ensure that there is space between the bottom of the DTU main body and the wall after the main body is mounted on the wall, so as to facilitate air circulation for heat dissipation, and fix the lower heat dissipation component in this space. After the main body of the DTU is mounted on the wall, the side heat dissipation fins of the two side heat dissipation components accelerate the heat dissipation effect on both sides of the DTU main body, and the bottom heat dissipation fins of the lower heat dissipation component dissipate heat to the bottom surface of the DTU main body, avoiding the phenomenon of overheating caused by close contact with the wall after the main body is mounted on the wall, thereby improving the overall heat dissipation effect.

The side heat dissipation component can be quickly replaced and selectively installed as needed after the DTU body is wall-mounted, which improves flexibility and convenience. It solves the problem that the existing DTU terminal equipment relies on a single metal shell for heat dissipation, has low heat dissipation efficiency, is prone to overheating, and affects the normal use of the DTU terminal equipment. In addition, after the DTU terminal equipment is fixed on the wall, the back is in close contact with the surface of the fixed object, and the connection is more likely to overheat, resulting in poor heat dissipation effect of the DTU terminal equipment.

[0015] 2. By setting limit rotating plates on the upper ends of both sides of the DTU body, one end of the threaded fastener passes through the limit rotating plate and is threadedly fixed to the fastener hole. The limit rotating plate is rotated so that one end of the limit rotating plate is located at the upper end of the side heat dissipation component and contacts the upper surface of the side heat dissipation component for extrusion and fixation. This has the effect of limiting the side heat dissipation component and preventing it from falling, thereby improving stability. BRIEF DESCRIPTION OF THE DRAWINGS
