[0022] Example: Reference Figure 1-4 The heat pipe radiator shown includes a device base 1, a semiconductor cooling sheet 17 and a face recognition machine 2. The semiconductor cooling sheet 17 is composed of a cold sheet and a hot sheet assembly. The bottom of the device base 1 is fixedly connected to a connecting seat 5 through a metal tube 4, and the device base 1, the metal tube 4 and the inner cavity of the connecting seat 5 are conductive. The face recognition machine 2 is embedded in the front end surface of the device base 1. A heat pipe box 15 is fixedly connected inside the device base 1. The cold sheet and the hot sheet are respectively fixed to the inner and outer walls of the front end surface of the heat pipe box 15. The hot sheet is fixedly connected to a heat sink 16 abutting against the rear end surface of the face recognition machine 2, and a heat exchanger 18 is fixedly connected to the outer wall of the heat pipe box 15.

[0023] The semiconductor refrigeration chip 17 has two thermal conductive plates. The thermal conductive plate for inputting cold is placed inside the heat pipe box 5 to provide a stable cold source for the face recognition machine. The heat pipe box 15 can timely conduct away the heat input from the hot surface of the semiconductor refrigeration chip 17. If the input heat cannot be conducted away, the refrigeration will fail or the semiconductor refrigeration chip 17 will burn out. Therefore, heat exchangers 18 are connected on both sides of the heat pipe box 15 to assist the heat pipe box 15 in heat dissipation. The heat dissipated by the two sets of heat exchangers 18 will be transferred to the inner cavity of the device base 1. A channel is also formed between the metal tube 4, the device base 1 and the connecting seat 5, so that heat is exchanged with the heat in the inner cavity of the device base 1, thereby further improving the heat dissipation effect, and the metal tube 4 can also be directly used as a bracket for the device base 1.

[0024] A fixing plate 13 is fixedly connected to the top of the connecting seat 5, the outer surface wall of the bottom of the metal tube 4 is slidably matched with the inner surface wall of the top of the connecting seat 5, and the outer surface wall of the metal tube 4 is overlapped with a fixedly matched strap 8 and a fixing frame 6, a linkage part for vertical linkage of the strap 8 and the metal tube 4 is provided between the strap 8 and the metal tube 4, a positioning part for vertical positioning of the fixing frame 6 is provided between the fixing plate 13 and the fixing frame 6, the linkage part includes a protrusion 7 fixedly installed on the outer surface wall of the metal tube 4, and the outer surface wall of the protrusion 7 is inserted into the inner surface wall of the strap 8 through a slot, the adjacent surfaces of the strap 8 and the fixing frame 6 are in contact with each other, and the strap 8 and the fixing frame 6 are fixedly connected by a mounting rod 9;

[0025] By rotating the positioning rod 12 to make its open end detach from the outer wall of the bottom rod 10, the bottom rod 10 and the fixing frame 6 lose their restraint. At this time, the equipment base 1 is vertically moved, and the equipment base 1 will drive the metal tube 4 to slide and cooperate with the connecting seat 5 until the equipment base 1 reaches the specified height. At this time, the position of the metal tube 4 is locked by the positioning rod 12, so that the height of the equipment base 1 can be adjusted, and the sealing gasket 14 connected between the fixing plate 13 and the metal tube 4 always ensures the airtightness of the connection between the metal tube 4 and the inner cavity of the connecting seat 5.

[0026] The front face of the device base 1 is integrated with multiple groups of rectangularly distributed LED fill lights 3 to fill in the front face light, solving the problem of outdoor backlight failure.

[0027] The positioning part includes a bottom rod 10 and a sleeve rod 11 that are slidably matched. The bottom rod 10 and the sleeve rod 11 are fixedly connected to the fixing frame 6 and the fixing plate 13 respectively. The inner wall of the sleeve rod 11 is screwed with a positioning rod 12, and the open end of the positioning rod 12 abuts against the outer wall of the bottom rod 10. The positioning rod 12 is rotated to make its open end close to the outer wall of the bottom rod 10, so that the bottom rod 10 and the sleeve rod 11 are fixed by friction. The inner wall of the fixing plate 13 is fixedly connected with a sealing gasket 14, and the inner wall of the sealing gasket 14 is tightly fitted with the outer wall of the metal tube 4. The sealing gasket 14 connected between the fixing plate 13 and the metal tube 4 always ensures the airtightness of the connection between the metal tube 4 and the inner cavity of the connecting seat 5.

[0028] Working principle of the utility model: the semiconductor refrigeration sheet 17 has two thermal conductive sheets, and the thermal conductive sheet for inputting cold is placed inside the heat pipe box 5 to provide a stable cold source for the face recognition machine. The heat pipe box 15 can timely conduct away the heat inputted from the hot surface of the semiconductor refrigeration sheet 17. If the input heat cannot be conducted away, the refrigeration will fail or the semiconductor refrigeration sheet 17 will burn out. Therefore, heat exchangers 18 are connected on both sides of the heat pipe box 15 to assist the heat pipe box 15 in heat dissipation. The heat dissipated by the two sets of heat exchangers 18 will be transferred to the inner cavity of the device base 1. A channel is also formed between the metal tube 4, the device base 1 and the connecting seat 5, so as to exchange the heat with the heat of the inner cavity of the device base 1, thereby further improving the heat dissipation effect. The metal tube 4 can also be directly used as a bracket for the device base 1.

[0029] By rotating the positioning rod 12 to make its open end detach from the outer wall of the bottom rod 10, the bottom rod 10 and the fixing frame 6 lose their restraint. At this time, the equipment base 1 is vertically moved, and the equipment base 1 will drive the metal tube 4 to slide and cooperate with the connecting seat 5 until the equipment base 1 reaches the specified height. At this time, the position of the metal tube 4 is locked by the positioning rod 12, so that the height of the equipment base 1 can be adjusted, and the sealing gasket 14 connected between the fixing plate 13 and the metal tube 4 always ensures the airtightness of the connection between the metal tube 4 and the inner cavity of the connecting seat 5.
