Description

Technical Field

[0001] This utility model relates to an electrical box, and more particularly to an electrical box for a printing press. Background Technology

[0002] Currently, the electrical box of a printing press is a metal enclosure with a door. Inside, the printing press circuit boards and electrical switches are arranged. Because the circuit boards generate heat during operation, and the electrical box is sealed for dust prevention, the air circulation inside the box is poor, resulting in poor heat dissipation. This can cause the electrical switches inside the box to trip, preventing the printing press from operating normally. Summary of the Invention

[0003] In view of the above-mentioned shortcomings, the purpose of this utility model is to provide an electrical box for a printing press with good heat dissipation.

[0004] The technical content of this utility model is as follows: an electrical box for a printing press, comprising an electrical box body, characterized in that it further comprises a heat dissipation box body, a first cooling fan, a second cooling fan, a sealing partition, a first dust filter cover, a second dust filter cover, and a radiator; the radiator is a double-row aluminum fin type; the heat dissipation box body is disposed on the side of the electrical box body; the sealing partition is vertically disposed in the middle of the heat dissipation box body, the sealing partition dividing the heat dissipation box body into an outer box chamber and an inner box chamber, the radiator is disposed in the middle of the sealing partition, the two rows of aluminum fins on the radiator are respectively located in the outer box chamber and the inner box chamber, the first cooling fan is disposed on the heat dissipation box body above the outer box chamber, the first dust filter cover is disposed on the heat dissipation box body below the outer box chamber; the second dust filter cover is disposed on the heat dissipation box body above the inner box chamber, and the second cooling fan is disposed on the heat dissipation box body below the inner box chamber.

[0005] The advantages of this utility model compared with the prior art are as follows: This utility model uses a second cooling fan to dissipate the heat inside the electrical box through the radiator and the first cooling fan, thereby achieving the effect of cooling the electrical box of the printing press. This allows the printing press circuit boards and electrical components inside the electrical box to work normally, thus not affecting the normal operation of the printing press. Attached Figure Description

[0007] Figure 2 This is a schematic diagram of the heat sink in this utility model. Detailed Implementation

[0008] like Figure 1 and Figure 2As shown, an electrical box for a printing press includes an electrical box body 1, characterized in that it further includes a heat dissipation box body 2, a first cooling fan 3, a second cooling fan 4, a sealing partition 5, a first dust filter cover 6, a second dust filter cover 7, and a radiator 8; the radiator 8 is a double-row aluminum fin type; the heat dissipation box body 2 is disposed on the side of the electrical box body 1; the sealing partition 5 is vertically disposed in the middle of the heat dissipation box body 2, and the sealing partition 5 divides the heat dissipation box body 2 into an outer chamber 2.1 and an inner chamber 2.2, the radiator 8 is disposed in the middle of the sealing partition 5, and the two rows of aluminum fins on the radiator 8 are respectively located in the outer chamber 2.1 and the inner chamber 2.2, the first cooling fan 3 is disposed on the heat dissipation box body 2 above the outer chamber 2.1, the first dust filter cover 6 is disposed on the heat dissipation box body 2 below the outer chamber 2.1; the second dust filter cover 7 is disposed on the heat dissipation box body 2 above the inner chamber 2.2, and the second cooling fan 4 is disposed on the heat dissipation box body 2 below the inner chamber 2.2.

[0009] The working principle of this utility model is as follows: the second cooling fan 4 blows the hot air in the electrical box 1 into the inner chamber 2.2, and then the air is cooled by the radiator 8 before entering the electrical box 1 through the second dust filter cover 7. At the same time, the first cooling fan 3 blows the air in the outer chamber 2.1 out of the outer chamber 2.1. The air outside the electrical box 1 enters the outer chamber 2.1 through the first dust filter cover 6 and exchanges heat with the radiator 8 to cool the radiator 8. Then the air is discharged from the outer chamber 2.1 by the first cooling fan 3, thereby achieving the cooling effect inside the electrical box 1.
