[0029] The coolant in the box body 2 3 is sucked into the cooling pipe 4 by the water pump 1 33, and the coolant is circulated by the internal structure of the box body 1 2. After the circulation, the coolant enters the coolant concentration tank 341 in the box body 2 3 again, and the excess heat in the coolant is discharged to the outside by the action of the I-shaped heat conductive plate 343 and the heat sink 344. After the heat is discharged, it flows into the box body 2 3 through the liquid outlet 345, and at the same time, the coolant is cooled by starting the cooler 31 and through the vertical pipe 32. The model of the cooler 31 is Minichiller 280 OLÉ, and the I-shaped heat conductive plate 343, the strip port 1, the strip port 2 and the coolant concentration tank 341 are arranged in the vertical direction to slow down the flow rate of the coolant, thereby achieving better heat dissipation.

[0030] like Figure 4 As shown, a plate 21 is fixedly connected to the upper part of the inner wall of the box body 2, an inclined surface is arranged on the upper surface of the plate 21, a partition 22 is fixedly connected to the rear side of the lower surface of the plate 21, a heat conducting plate 23 is fixedly connected to the upper part of the inner wall of the box body 2, a partition 24 is fixedly connected to the front and rear sides of the upper surface of the heat conducting plate 23, a water pump 28 is fixedly connected to the front side of the lower surface of the inner wall of the box body 2, the output end of the water pump 28 passes through the outside of the box body 2 and is fixedly connected to the right end of the cooling pipe 4, a plurality of circular holes 1 are opened on the rear side of the upper surface of the partition 24, and the lower surface of the heat conducting plate 23 is fixedly connected to the upper part of the heat conducting plate 23. A plurality of T-shaped plates 27 are fixedly connected to the rear side, and an inclined plate 26 is fixedly connected to the rear side of the outer surfaces of the plurality of T-shaped plates 27.

The outer surface of the heat conducting plate 25 is fixedly connected to the inner wall of the box body 2. A plurality of circular holes 2 are opened on the front side of the upper surface of the heat conducting plate 25, which are connected up and down. The I-shaped heat conducting plate 343, the heat sink 344, the heat conducting plate 1 23, the heat conducting plate 25, the inclined plate 26, and the T-shaped plate 27 are made of copper.

[0031] Through the action of water pump 1 33 and cooling pipe 4, the coolant enters into box body 1 2, and flows to heat conducting plate 1 23 due to the setting of inclined surface in plate 21, and the flow speed of coolant is slowed down through the setting of partition 1 22 and partition 2 24, and the coolant flows to heat conducting plate 2 25 through the setting of circular hole 1, and the coolant has a certain storage effect through the setting of inclined plate 26. When a large amount of coolant passes through the top of inclined plate 26 and flows to the bottom of box body 1 2 through circular opening 2, it is sucked by water pump 2 28 and enters into box body 2 3 through pipe 5, so as to realize the circulation effect. The setting of inclined plate 26, heat conducting plate 1 23, heat conducting plate 25 and T-shaped plate 27 slows down the flow speed of coolant and transfers heat to the outside, so as to realize the effect of heat dissipation and cooling of excess heat of coolant.

[0032] like Figure 5 - Figure 6As shown, the front and rear sides of the heat sink 1 are provided with square openings that communicate with the inside and outside, and the inner wall of the rear square opening is fixedly connected with a dustproof net 11, the front sides of the upper and lower surfaces of the heat sink 1 are provided with grooves 12, and the rear side of the grooves 12 is provided with a plurality of positioning grooves 13, the adjustment component 6 includes a slide bar 61, the left and right ends of the slide bar 61 are fixedly connected with vertical blocks 62, the lower surface of the vertical block 62 is fixedly connected to the upper surface of the heat sink 1, the outer surface of the slide bar 61 is slidably connected with a T-shaped block 63, the outer surface of the T-shaped block 63 is provided with a mounting hole that communicates with the front and rear, a tightening component 64 is fixedly connected to the lower rear side of the T-shaped block 63, and a positioning block 65 is fixedly connected to the rear end of the tightening component 64, the outer surface of the positioning block 65 is plugged into the inside of one of the positioning grooves 13, and the tightening component 64 includes a spring 641 and a telescopic shaft 642, and the outer surface of the spring 641 is sleeved with the inside of the telescopic shaft 642;

[0033] By moving the positioning block 65, the positioning block 65 is separated from the interior of the positioning groove 13. At this time, the positions of the telescopic shaft 642 and the spring 641 are in a retracted state. Then, by moving the T-block 63 and sliding on the surface of the slide rod 61, the installation position can be adjusted. After the position is adjusted, the positioning block 65 is released, and the elastic action of the spring 641 pushes the positioning block 65 to move and enter the interior of the positioning groove 13, so as to facilitate the restriction of the adjusted position. The installation hole in the T-block 63 is set to facilitate the installation and connection with the chlor-alkali chemical electrical equipment through the fixing bolt.

[0034] The following is a detailed description of the working principle of the heat dissipation device for chlor-alkali chemical electrical equipment.

[0035] The coolant is sucked in the cooling pipe 4 by the water pump 33. When the chlor-alkali chemical electrical equipment is working, the heat is allowed to enter the heat dissipation box 1 through the heat dissipation port and contact the cooling pipe 4, so that the heat is transferred inside and contacts the coolant to cool down and dissipate heat. At the same time, the coolant enters the box body 2, and the speed of the coolant flow is slowed down by the setting of the plate 21, the heat conducting plate 23, the partition 1 22, the partition 24, and the inclined plate 26. The setting of the inclined plate 26, the heat conducting plate 1 23, the heat conducting plate 25, and the T-shaped plate 27 slows down the flow rate of the coolant and transfers the heat to the outside, thereby achieving the effect of dissipating and cooling the excess heat of the coolant. After the coolant circulates and enters the coolant concentration box 341 in the box body 2 3 again, The interior is provided with an I-shaped heat conducting plate 343 and a heat sink 344, thereby discharging excess heat in the coolant to the outside. After the heat is discharged, it flows into the box body 2 3 through the liquid outlet 345. At the same time, the coolant is cooled by the cooler 31 to complete the operation. The positioning block 65 is moved to separate the positioning block 65 from the interior of the positioning groove 13. At this time, the positions of the telescopic shaft 642 and the spring 641 are in a retracted state. The T-shaped block 63 is moved and slides on the surface of the slide rod 61 to achieve the effect of adjusting the installation position. After the position is adjusted, the positioning block 65 is released due to the elastic action of the spring 641, thereby pushing the positioning block 65 to move and enter the interior of the positioning groove 13, thereby facilitating the restriction of the adjusted position.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
