Referring to FIG. 1 , the heating component 2 may be electronic components such as a control circuit board, a CPU, and the like.

As shown in FIG. 1 , the heat dissipation assembly includes a heat dissipation frame 1 , a fan 3 , an air duct 4 , a thermally conductive silica gel 5 and a power supply assembly 6 . The heat dissipation frame 1 includes a bottom plate and a side plate. The side plate extends vertically from the bottom plate to form an accommodating slot 11 (see FIG. 2 ) around the bottom plate. The fan 3 and the air duct 4 are accommodated in the accommodating slot. The heating component 2 is installed on one side of the heat dissipation frame 1 , specifically the outside of the bottom plate. The thermally conductive silica gel 5 is sandwiched between the bottom plate and the heating element 2 to improve the heat flow efficiency. The heat dissipation frame 1 is provided with a heat dissipation exhaust port 12 and a heat dissipation air inlet 13 . Specifically, the heat dissipation exhaust port 12 and the heat dissipation air intake 13 are provided on the side plate, and are provided with a plurality of them at intervals.

Specifically, the panel has a heat detector module 7 and an associated control system. In particular, due to the overall layout of the panel, the heat detector module 7 is installed in the middle of the top edge of the heat dissipation frame 1 .

In this embodiment, the panel has a temperature sensor and associated control system. The temperature sensor monitors the internal temperature of the accommodating groove 11 in the panel. When the internal temperature of the accommodating tank 11 is lower than the set value, the fan 3 will not start; when the internal temperature of the accommodating tank 11 is greater than or equal to the set value, the temperature sensor transmits a signal to the relevant control system to start the fan 3 .

Referring to FIGS. 2 and 3 , the heat dissipation vents 12 are arranged on the top of the heat dissipation frame 1 , including a first group of heat dissipation exhaust ports 121 and a second group of heat dissipation exhaust ports 122 , and the two groups of exhaust ports are respectively located at the top of the heat dissipation frame 1 .

Assuming that the hot air is discharged from the bottom or both sides of the heat dissipation frame 1 , the hot air will still rise, which may cause misjudgment by the heat detector module 7 .

Specifically, the heat dissipation slot 14 is provided outside the side plate of the heat dissipation frame 1, which enhances the efficiency of heat conduction and radiation directly from the heat dissipation frame 1 to the outside.

In this embodiment, the fan 3 is a ball bearing type electric centrifugal fan with a silent high air volume, including a rotor and a casing. The rotor can suck air in from the axial direction of the rotor, and then use centrifugal force to blow the air out from its circumferential direction.

Referring to FIG. 4 , the casing of the fan 3 is provided with fan air inlets 31 on both axial sides of the rotor, that is, on both sides of the fan 3 . The casing of the fan 3 is provided with a fan exhaust port 32 on the upper part of the rotor, that is, on the top of the fan 3 .

Specifically, the arrow marks in FIG. 4 represent the airflow direction when the fan 3 is operating. The air duct 4 guides the hot air discharged from the fan exhaust port 32 to be led out through itself and the heat dissipation exhaust port 12, so as to prevent the hot air from blowing directly on the top center of the heat dissipation frame 1, and ensure that the heat detector module 7 will not misjudge.

Specifically, the air duct 4 is made of flame-retardant plastic. Flame retardant plastic is a modified PC with ABS added, which has the properties of heat resistance, flame retardant and good formability.

Referring to FIG. 5 , the power supply assembly 6 is used to supply power to the relevant electrical components of the panel including the fan 3 . The casing has a heat dissipation slot 61 for the power supply assembly, which enhances the efficiency of the heat generated by the power supply assembly 6 being conducted and radiated to the outside through the casing.
