Figure 1-5 As shown, the control device includes a control cabinet 1 and a control body 2, the control body 2 is installed inside the control cabinet 1, a heat dissipation hole 3 is opened on the rear surface of the control cabinet 1, the inner wall of the control cabinet 1 is connected to two limit rails 4, a heat dissipation plate 5 is arranged between the two limit rails 4, a hydraulic telescopic rod 6 is installed between the bottom of the heat dissipation plate 5 and the inner wall of the control cabinet 1, the surface of the hydraulic telescopic rod 6 is connected to a connecting wire 7, and the end of the connecting wire 7 is connected to a temperature control switch 8.

[0026] Among them, the cross-section of the limiting track 4 is L-shaped, the heat sink 5 and the limiting track 4 are slidingly connected, the surface of the heat sink 5 is provided with square holes matching the heat sink holes 3, and a hydraulic lifting structure is formed between the heat sink 5 and the hydraulic telescopic rod 6.

[0027] In actual use, the hydraulic telescopic rod 6 can squeeze the heat sink 5 when it is extended. The heat sink 5 can move upward on the inner wall of the limiting track 4 under the squeezing, so that the position of the heat sink 5 can be adjusted.

[0028] Secondly, the model of the temperature control switch 8 is KSD-302, and the temperature control switch 8 and the hydraulic telescopic rod 6 are electrically connected through the connecting wire 7.

[0029] In actual use, when the temperature monitored by the temperature probe exceeds the set maximum value, the temperature control switch 8 can be turned on and the operation of the hydraulic telescopic rod 6 can be controlled by connecting the wire 7.

[0030] Next, a water channel 9 is provided on one side of the control cabinet 1 , and a rubber strip 10 is connected to the side surface of the water channel 9 .

[0031] In actual use, the rubber strip 10 can be used to seal the control cabinet 1 and the water guide groove 9, thereby preventing water from seeping downward from the control cabinet 1.

[0032] In addition, a connecting block 11 is connected to the side surface of the water channel 9. A fixing hole 12 is opened on the surface of the connecting block 11. A fixing bolt 13 passes through the fixing hole 12. A threaded hole 14 is opened on the surface of the control cabinet 1 near the fixing bolt 13.
