Description

Technical Field

[0001] This utility model relates to the field of welding machines, and specifically to an adjustable radiator for welding machines. Background Technology

[0002] An electric welding machine is a device that uses the high-temperature electric arc generated when positive and negative electrodes are short-circuited for a moment to melt objects and then join them together. Electric welding machines are mainly used in the industrial and mining industries. When an electric welding machine is working, it will generate extremely high temperatures in an instant. If it is not cooled down during long-term operation, the device is prone to self-damage.

[0003] Existing welding machines typically use fans and cooling grilles on the welding machine casing for heat dissipation. The fans are located at the rear of the casing, and the cooling grilles are located on both sides. Airflow enters the casing through the fans and exits through the cooling grilles. However, in actual use, it has been found that the frequency converter is often located at the front of the welding machine casing. In such welding machines, the airflow moves from rear to front, making it difficult to effectively dissipate heat from the frequency converter.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of ineffective heat dissipation of electrical components in existing welding machines, this utility model provides an adjustable heat sink for welding machines. The adjustable heat sink includes: a housing having a rear wall, a top wall, and side walls; at least two cooling fans mounted on the rear wall; and an air guiding structure including air ducts with their ends facing the cooling fans and the frequency converter respectively, and an adjusting plate mounted on the end of the air duct facing the cooling fans; the adjusting plate is rotatably mounted on the air duct and configured to adjust the size of the air inlet of the air duct.

[0006] This utility model discloses an adjustable heat sink for welding machines, comprising a housing, a cooling fan, and an air guide structure. The cooling fan and air guide structure are mounted on the housing. The air guide structure includes an air duct and an adjusting plate. One end of the air duct faces the cooling fan, and the other end faces the frequency converter, directly delivering the airflow from the cooling fan to the frequency converter for cooling. The adjusting plate is rotatably mounted on the air duct and can adjust the size of the air inlet, thereby regulating the airflow entering the air duct; a larger air inlet results in a larger airflow and better cooling effect on the frequency converter. Through the above design, this utility model's adjustable heat sink for welding machines can directly cool the frequency converter, preventing overheating and damage, and the adjustable airflow into the air duct meets the needs of various cooling conditions.

[0007] Furthermore, the air duct includes a partition wall installed on the side wall and a baffle plate arranged at one end of the partition wall; the partition wall and the baffle plate form an air outlet facing the frequency converter.

[0008] Furthermore, a heat dissipation grille is provided on the top wall.

[0009] Furthermore, one side of the adjusting plate is hinged to the surrounding plate, and the other side is provided with an adjusting rod; an adjusting groove matching the adjusting rod is provided on the rear wall.

[0010] Furthermore, a dustproof cloth is provided on the rear wall to enclose the adjustment groove; the dustproof cloth is connected to the adjustment rod.

[0011] Furthermore, the housing also includes a bottom wall arranged opposite to the top wall, and a mounting post is provided between the enclosure and the bottom wall.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] The air guide structure includes an air duct and an adjustment plate. One end of the air duct faces the cooling fan, and the other end faces the inverter. It can directly deliver the airflow blown out by the cooling fan to the inverter to dissipate heat. The adjustment plate is rotatably mounted on the air duct and can adjust the size of the air inlet of the air duct, thereby adjusting the air volume entering the air duct. The larger the air inlet, the more airflow, and the better the heat dissipation effect on the inverter. Attached Figure Description
