The size of the groove 143 is just enough to accommodate the third closed ring The closed loop 8 and the first closed loop 3, the first closed loop 141 and the second closed loop 147 are wrapped around the third closed loop 8 and the first closed loop 3 to form a triangular shape as a whole. Then, the block 1410 is inserted into the slot 142 at the front end of the first closed loop 141 and the second closed loop 147. At this time, the preliminary fixation between the main body 1 and the head 6 is completed. Finally, the screw 146 is used to fix it through the screw holes 145 opened on the first bracket 144 and the second bracket 148 respectively. At this time, the installation of the main body 1 is completed. Compared with the conventional method of fixing by multiple groups of bolts, the device is more convenient to install by installing the sealing mechanism 14, and it is easy to disassemble. The screw 146 is removed from the first bracket 144 and the second bracket 148, and then the block 1410 is removed from the slot 142, so that the head 6 and the cold material device 10 can be separated from the main body 1, which is convenient for cleaning the heat pipe in the main body 1 to avoid dust accumulation that increases the thermal resistance of the heating surface and reduces the heat transfer capacity of the equipment.

[0031] By adopting the above technical solution, the design of the installation sealing mechanism 14 can improve the fixing ability of the main body 1 after installation. The size of the groove 143 provided in the first closed ring 141 and the second closed ring 147 is just the size after the third closed ring 8 and the first closed ring 3 are closed. The installation sealing mechanism 14 is triangular in shape as a whole. The first closed ring 141 and the second closed ring 147 are fixed by the clamping block 1410. After fixation, the first closed ring 141 and the second closed ring 147 complete the fixation of the main body 1 and the head 6. Then, the installation sealing mechanism 14 is installed by the screw 146 to fix the main body 1. After fixation, the installation sealing mechanism 14 restricts the first bracket 144 and the second bracket 148, so that the rear ends of the first bracket 144 and the second bracket 148 are close to the wall surface for installation, so that the installation sealing mechanism 14 cannot be as Figure 4 As shown, the installation sealing ability of the installation sealing mechanism 14 on the main body 1 is further improved, and it has a double fixing ability. The triangular structural design enables the installation sealing mechanism 14 to have good stability after installation.

After the main body 1, the head 6 and the cold material device 10 are installed, the installation sealing mechanism 14 is used to fix them. First, the first closed loop 141 is connected to the second closed loop through the rotating shaft 149. The first closed ring 141 and the second closed ring 147 are separated, and the first closed ring 141 and the second closed ring 147 are sleeved on the third closed ring 8 and the first closed ring 3 by using the groove 143 provided in the first closed ring 141 and the second closed ring 147. The size of the groove 143 is just enough to accommodate the third closed ring 8 and the first closed ring 3. After the first closed ring 141 and the second closed ring 147 sleeve the third closed ring 8 and the first closed ring 3, the whole is triangular in shape. Then, the clamping block 1410 is clamped into the clamping groove 142 at the front end of the first closed ring 141 and the second closed ring 147. At this time, the preliminary fixation between the main body 1 and the head 6 is completed. Finally, the screw 146 is used to pass through the first bracket 144 and the second bracket respectively. The screw holes 145 opened on the bracket 148 can be used to fix the main body 1. At this time, the installation of the main body 1 is completed. Compared with the conventional method of fixing by multiple sets of bolts, the design of the installation sealing mechanism 14 of the present device is more convenient to install and easy to disassemble. The screw rod 146 is removed from the first bracket 144 and the second bracket 148, and the block 1410 is taken out from the slot 142, so that the head 6 and the cold material device 10 can be separated from the main body 1, which is convenient for cleaning the heat pipe in the main body 1, avoiding dust accumulation to increase the thermal resistance of the heating surface and reduce the heat transfer capacity of the equipment. The design of the installation sealing mechanism 14 can improve the fixing ability of the main body 1 after installation. The first closed loop 141 and the second closed loop The size of the groove 143 opened in 147 is just the size after the third closed loop 8 and the first closed loop 3 are closed. The overall shape of the installation sealing mechanism 14 is triangular. The first closed loop 141 and the second closed loop 147 are fixed by the clamping block 1410. After the fixation, the first closed loop 141 and the second closed loop 147 complete the fixation of the main body 1 and the head 6. Then the installation sealing mechanism 14 is installed by the screw 146 to fix the main body 1. After the installation sealing mechanism 14 is fixed, the first bracket 144 and the second bracket 148 are restricted so that the rear ends of the first bracket 144 and the second bracket 148 are close to the wall surface for installation, so that the installation sealing mechanism 14 cannot be as Figure 4 As shown, the installation sealing ability of the installation sealing mechanism 14 on the main body 1 is further improved, and it has a double fixing ability. The triangular structural design enables the installation sealing mechanism 14 to have good stability after installation.
