Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating equipment, and in particular relates to a rectifier used for electroplating processing. Background Art

[0002] The electroplating process is a surface treatment process that uses the principle of electrolysis to plate a layer of other metals or alloys on certain metal surfaces. The plating layer prevents metal oxidation, improves wear resistance, conductivity, reflectivity, corrosion resistance, and enhances aesthetics. The electroplating process involves injecting electrolyte into an electrolytic cell, placing the metal workpiece to be electroplated in the electrolytic cell, and then using a rectifier to convert alternating current into direct current. The rectifier is connected to the electrolytic cell to achieve the electrolysis process, thereby completing the electroplating process. However, during the use of the rectifier, the rectifier mechanism of the rectifier will generate a lot of heat, which needs to be dissipated by a heat dissipation mechanism to avoid excessively high temperatures in the rectifier mechanism, which will affect the service life of the rectifier.

[0003] In the prior art, the heat dissipation mechanism of the rectifier usually includes a heat dissipation fan and a vent on the chassis, but the heat dissipation efficiency is low. The existing heat dissipation mechanism also has a plurality of heat sinks arranged in an array mounted on the heat dissipation fan. This method increases the heat dissipation area and improves the heat dissipation efficiency. However, the contact time between the heat dissipation fan and the heat sink is short, and the heat sink cannot fully exchange heat, so the heat dissipation efficiency is limited. Utility Model Content

[0004] The purpose of the utility model is to provide a rectifier for electroplating processing in response to the above-mentioned technical problems, in which the heat generated by the rectifier mechanism is transferred to the heat sink, and the cooling fan blows cold air through multiple heat sinks. The multiple heat sinks increase the heat dissipation area, and the wind generated by the cooling fan flows smoothly in the multiple heat dissipation channels of the heat sink, prolonging the time that the wind contacts the heat sink, so that the heat sink can fully exchange heat and improve the heat dissipation efficiency.

It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0031] Embodiment 1:

[0032] This embodiment provides a rectifier for electroplating, comprising:

[0033] The invention comprises a chassis, a rectifying mechanism arranged in the chassis, an operation panel installed on the chassis and a heat dissipation mechanism installed on the chassis, wherein the heat dissipation mechanism comprises:

[0034] A cooling fan 1 is installed on one side of the inner wall of the chassis;

[0035] The heat sink 2 is installed inside the heat sink fan 1, and the heat sink 2 includes a frame 21 and a plurality of heat sinks 22 arranged in the frame 21;

[0036] Among them, the heat sink 22 includes a first sheet 221, a second sheet 222 and a third sheet 223 which are arranged in sequence from the outside to the inside, and heat dissipation channels are respectively formed between two adjacent first sheets 221, between two adjacent second sheets 222 and between two adjacent third sheets 223; 3, the outer end of the second sheet 222 is bent along one side of the X-axis to provide a first guide sheet 224, the outer end of the third sheet 223 is bent along the other side of the X-axis to provide a second guide sheet 225, and two first heat dissipation ports 5 are formed between the outer end of the first guide sheet 224 and the inner ends of the two adjacent first sheets 221, and two second heat dissipation ports 6 are formed between the outer end of the second guide sheet 225 and the inner ends of the two adjacent first sheets 221, and a vent 4 is provided on the side of the chassis away from the heat sink 2.

[0037] In this technical solution, if Figure 1-Figure 3As shown, the chassis may be a rectangular parallelepiped, the rectifier mechanism may be an existing rectifier mechanism capable of converting AC power into DC power, and the rectifier may include a rectifier transformer, a rectifier bridge, a filter capacitor, and a control circuit. The operation panel may include a plurality of operation switches and a display screen, and the operation panel is used to operate the rectifier and observe the working status of the rectifier. The heat dissipation mechanism is used to dissipate the heat generated by the rectifier mechanism.

[0038] Among them, Figure 4 As shown, the heat dissipation fan 1 of the heat dissipation mechanism can be an existing conventional heat dissipation fan 1, a window can be opened on the left side of the chassis, and the heat dissipation fan 1 can be installed on the inner side of the window by using screws.

[0039] like Figure 4-Figure 6 As shown, a plurality of heat sinks 22 of the heat sink 2 are arranged and installed in a frame 21, and the plurality of heat sinks 22 are parallel to each other.

[0040] When the rectifier mechanism is running, heat is generated, and the heat generated by the rectifier mechanism is first transferred to the heat sink 22. The main function of the cooling fan 1 is to blow cold air through the multiple heat sinks 22 to accelerate the exchange of heat with the external air. The wind generated by the cooling fan 1 blows toward the multiple heat sinks 22 to take away the hot air and introduce more cold air to maintain a relatively low temperature on the surface of the heat sink 22.

[0041] Among them, the vent 4 arranged on the side of the chassis away from the heat sink 2 can be an air outlet, and the window close to the cooling fan 1 can be an air inlet. The air inlet is responsible for introducing cold air from the outside, while the air outlet discharges the heat-saturated air in the chassis. The vent 4 and the window can achieve good air flow so that the heat inside the device can be effectively taken out, thereby improving the heat dissipation efficiency. The cooling fan 1 can accelerate the air flow and enhance the heat dissipation effect.

[0042] The wind generated by the cooling fan 1 first blows toward the cooling channel between the two adjacent first sheets 221; 3, and then the wind is guided to the two first cooling ports 5 respectively through the first guide plate 224, so that the wind flows to the cooling channels on both sides of the second sheet 222; 3, and then the wind is further guided to the two second cooling ports 6 respectively through the second guide plate 225, so that the wind flows to the cooling channels on both sides of the third sheet 223; 3.

[0043] The heat dissipation area is increased by multiple heat sinks 22 to improve the heat dissipation efficiency, and the wind generated by the heat dissipation fan 1 flows smoothly through the multiple heat dissipation channels of the heat sink 22; 3, the time for the wind to contact the heat sink 22 is extended, so that the heat sink 22 can fully exchange heat, further improving the heat dissipation efficiency.
