[0012] As a further solution of the utility model: a magnetic pad is installed on the inner side of the upper end of the guide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a heat dissipation structure of an industrial control cabinet, including a control cabinet 1 and a heat dissipation mechanism 2, characterized in that the heat dissipation mechanism 2 includes: a dust baffle 203, a filter 204, the outer side of the dust baffle 203 is located on the inner side of the control cabinet 1 and a baffle slot 205 is opened, the dust baffle 203 is snap-connected with the baffle slot 205, a guide slider 206 is installed on the outer side of the upper end of the dust baffle 203, the outer side of the guide slider 206 is located on the inner side wall of the control cabinet 1 and a guide groove 201 is installed, a magnetic pad is installed on the inner side of the upper end of the guide groove 201, a storage cylinder 207 is installed inside the guide groove 201, the storage cylinder 207 is made of a metal material with strong thermal conductivity, the interior of the storage cylinder 207 is filled with anhydrous ethanol, and it can also be a liquid that is easily expanded when heated, a piston rod 208 is arranged inside the storage cylinder 207 below the guide slider 206, and the lower end of the piston rod 208 is located inside the storage cylinder 207 and a sealing piston is installed.

[0024] like Figure 2-3 As shown, in this embodiment, a fan 209 is provided at one end of the heat dissipation mechanism 2 on the outside of the control cabinet 1, an electric control switch 202 is installed on the inner wall of the control cabinet 1 above the dust baffle 203, an electric control wire 3 is connected between the fan 209 and the electric control switch 202, the electric control wire 3 is electrically connected to the fan 209 and the electric control switch 202, a closed cabinet door 4 is installed on the front surface of the control cabinet 1, the closed cabinet door 4 is rotatably connected to the control cabinet 1, and a protective net 210 is installed on the outside of the fan 209.

[0025] The working principle of the utility model is as follows: when in use, the closed cabinet door 4 is in a sealed state as a whole. When the electrical components inside the control cabinet 1 are working, more heat will be generated. When the heat rises as a whole, the temperature of the storage cylinder 207 will rise as a whole. Then, the anhydrous ethanol inside the storage cylinder 207 will be heated and expanded as a whole under the action of heat transfer. The expanded liquid will move upward inside the storage cylinder 207 as a whole, so that the piston at the lower end of the piston rod 208 will be pushed upward inside the storage cylinder 207. The storage cylinder 207 will control the movement of the guide slider 206 to realize the control of the dust baffle. 203 is pushed upward as a whole inside the baffle slot 205, thereby disconnecting the dust baffle 203 from blocking the filter 204, and the passage between the heat dissipation mechanism 2 and the control cabinet 1 as a whole is opened, so that heat exchange between the control cabinet 1 and the outside can be achieved. When the dust baffle 203 is pushed upward as a whole to the uppermost position of the guide groove 201, the dust baffle 203 will squeeze the electric control switch 202, and open the electrical path of the fan 209 and the electric control wire 3. The magnetic block on the inner side of the upper end of the guide groove 201 will be adsorbed by the guide slider 206, and the fan 209 can be used to increase the heat exchange efficiency between the control cabinet 1 and the outside.
