Description

Technical Field

[0001] The utility model relates to the technical field of micro-arc oxidation power supplies, in particular to a micro-arc oxidation power supply with a heat dissipation structure. Background Art

[0002] Micro-arc oxidation power supply is a specially designed power supply device, which is mainly used to realize micro-arc oxidation process. This power supply can generate and control tiny arc discharge phenomenon on the surface of metal materials, thereby forming a hard and dense ceramic oxide film on the surface of the material, significantly improving the wear resistance, corrosion resistance and insulation performance of materials such as aluminum alloy and magnesium alloy.

[0003] The heat dissipation effect of some micro-arc oxidation power supplies is not ideal. Continuous high-temperature operation will cause the internal components of the power supply to age faster, reduce the stability and durability of electronic components, and thus shorten the service life of the entire power supply equipment. Poor heat dissipation will lead to reduced power supply efficiency, unstable output power, and inability to continuously provide stable high voltage and current, which will affect the stability of the micro-arc oxidation process and the quality of film generation.

Poor heat dissipation will lead to reduced power supply efficiency, unstable output power, and inability to continuously provide stable high voltage and current, which will affect the stability of the micro-arc oxidation process and the quality of film generation.

[0005] To achieve the above object, the utility model provides the following technical solution: a micro-arc oxidation power supply with a heat dissipation structure, comprising a power supply box, the power supply box comprising a box body, a battery body is arranged inside the box body, and a heat dissipation mechanism is arranged above the inner wall of the box body:

[0006] The heat dissipation mechanism includes an exhaust pipe fixed to the inside of the box body, a plurality of nozzles are fixedly connected to one side of the exhaust pipe, a cooling box is fixedly connected to the top of the box body, a condenser is arranged inside the cooling box, one end of the condenser passes through the cooling box and is fixedly connected between the box body and the top of the exhaust pipe, the other end of the condenser extends to the outside of the cooling box and is fixedly connected to a connecting pipe, one end of the connecting pipe is fixedly connected to the exhaust end of the fan, and the fan is fixedly connected to the top of the cooling box.

[0007] As a preferred micro-arc oxidation power supply with a heat dissipation structure of the utility model, a plurality of heat dissipation grooves are equidistantly opened on one side of the box body, a dustproof net is connected inside the heat dissipation groove, and a plurality of blocking covers are fixedly connected to one side of the box body, and the blocking covers are correspondingly arranged between the heat dissipation grooves.

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

[0014] 1. In the utility model, since the battery body generates a lot of heat after working for a long time inside the box, in order to avoid heat accumulation inside the box, the operator can start the fan, and the fan draws the gas in the environment into the fan and transports it to the inside of the condenser along the connecting pipe for cooling. In this way, the gas can exchange heat through the condenser, and the condensing medium such as water or refrigerant inside the cooling box absorbs a lot of heat to achieve cooling of the air inside the condenser. The cold air is transported to the inside of the exhaust pipe along the condenser and blown to the battery body along multiple nozzles. The exhaust pipe and multiple nozzles can effectively discharge the heat generated by the battery body when working into the box through the internal circulating air. The set nozzles can evenly disperse the airflow, increase the heat dissipation area, and help to quickly conduct and dissipate heat. The above design aims to achieve the effective discharge of high-temperature gas inside the power supply by combining internal circulation heat dissipation with external air cooling, and reduce heat accumulation by condensation cooling means, thereby ensuring that the battery body and other electrical components in the power box can operate stably and permanently at a suitable working temperature, avoiding various adverse effects caused by overheating, and effectively extending the service life of the entire power supply equipment.

[0015] 2. The utility model connects the circulating water pump with the bottom of the cooling box through a pumping pipe, so that the coolant can circulate. After being pressurized by the circulating water pump, the coolant is transmitted to the input end of the external refrigeration equipment through the drain pipe. The refrigeration equipment will cool the coolant to greatly reduce its temperature, providing a lower temperature cooling medium for the subsequent cooling cycle. The cooled low-temperature coolant then flows from the output end of the refrigeration equipment into the top of the cooling box through the water injection pipe. This design makes full use of the principle of gravity, allowing the low-temperature coolant to sink naturally, covering and contacting the condenser, thereby efficiently taking away the heat in the condenser. This liquid cooling circulation system greatly improves the heat dissipation performance of the micro-arc oxidation power supply, and is particularly suitable for high-power and long-term continuous working occasions. It can effectively suppress the internal temperature rise of the power supply, ensure the stable operation of the power supply equipment, extend its service life, and is conducive to improving the quality and efficiency of the micro-arc oxidation treatment.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 6 A micro-arc oxidation power supply with a heat dissipation structure includes a power supply box 1, the power supply box 1 includes a box body 101, a battery body 2 is arranged inside the box body 101, and a heat dissipation mechanism 3 is arranged above the inner wall of the box body 101:

[0024] Furthermore, the heat dissipation mechanism 3 includes an exhaust pipe 305 fixed inside the box body 101, a plurality of nozzles 306 are fixedly connected to one side of the exhaust pipe 305, a cooling box 301 is fixedly connected to the top of the box body 101, a condenser 302 is provided inside the cooling box 301, one end of the condenser 302 passes through the cooling box 301 and is fixedly connected between the box body 101 and the top of the exhaust pipe 305, the other end of the condenser 302 extends to the outside of the cooling box 301 and is fixedly connected to a connecting pipe 304, one end of the connecting pipe 304 is fixedly connected to the exhaust end of the fan 303, and the fan 303 is fixedly connected to the top of the cooling box 301.

[0025] Since the battery body 2 generates a lot of heat after working for a long time inside the box 101, in order to avoid heat accumulation inside the box 101, the operator can start the fan 303, and the fan 303 draws the gas in the environment into the fan 303 and transports it to the condenser 302 along the connecting pipe 304 for cooling. In this way, the gas can exchange heat through the condenser 302, and the condensing medium such as water or refrigerant inside the cooling box 301 absorbs a lot of heat to achieve cooling of the air inside the condenser 302. The cold air is transported along the condenser 302 to the exhaust pipe 305, and blown toward the battery body 2 along the multiple nozzles 306. The exhaust pipe 305 is 5 and multiple nozzles 306 can effectively discharge the heat generated by the battery body 2 when working out of the box body 101 through the internal circulating air. The set nozzles 306 can evenly disperse the airflow, increase the heat dissipation area, and help to quickly conduct and dissipate heat. The above design aims to achieve effective discharge of high-temperature gas inside the power supply through a combination of internal circulation heat dissipation and external air cooling, and reduce heat accumulation by condensation cooling, thereby ensuring that the battery body 2 and other electrical components in the box body 101 can operate stably and permanently at a suitable working temperature, avoiding various adverse effects caused by overheating, and effectively extending the service life of the entire power supply equipment.

[0026] Furthermore, a plurality of heat dissipation slots 102 are equidistantly provided on one side of the housing 101 , dustproof nets 103 are connected inside the heat dissipation slots 102 , and a plurality of blocking covers 104 are fixedly connected to one side of the housing 101 , and the blocking covers 104 are correspondingly arranged with the heat dissipation slots 102 .

[0027] The multiple heat dissipation slots 102 are provided to assist in heat dissipation. The purpose of designing these heat dissipation slots 102 is to enhance the air circulation inside and outside the box 101, and help transfer heat from the inside of the box 101 to the external environment, so as to achieve the effect of effective heat dissipation. On the one hand, the dustproof net 103 allows air to circulate smoothly to assist in heat dissipation; on the other hand, it can effectively block dust and other particles from entering the inside of the box 101, protect the power supply equipment from dust pollution, extend the life of the equipment, and also reduce the risk of reduced heat dissipation efficiency due to dust accumulation. The cover 104 can effectively prevent rainwater from entering the inside of the box 101.

[0028] Furthermore, a circulating water pump 4 is fixedly connected to one side of the box body 101 , a pumping end of the circulating water pump 4 is fixedly connected to a pumping pipe 6 , and one end of the pumping pipe 6 is fixedly connected to one side of the bottom of the cooling box 301 .

[0029] Furthermore, a drainage pipe 5 is fixedly connected to the drainage end of the circulating water pump 4, one end of which is fixedly connected to the input end of the external refrigeration equipment. A water injection pipe 307 is fixedly connected to one side of the top of the cooling box 301, and one end of the water injection pipe 307 is fixedly connected to the output end of the external refrigeration equipment.

[0030] The pumping pipe 6 connects the circulating water pump 4 with the bottom of the cooling box 301, so that the coolant can circulate. After being pressurized by the circulating water pump 4, the coolant is transmitted to the input end of the external refrigeration equipment through the drain pipe 5. The refrigeration equipment will cool the coolant to significantly reduce its temperature, providing a lower temperature cooling medium for the subsequent cooling cycle. The cooled low-temperature coolant then flows from the output end of the refrigeration equipment into the top of the cooling box 301 through the water injection pipe 307. This design makes full use of the principle of gravity, allowing the low-temperature coolant to sink naturally, covering and contacting the condenser 302, thereby efficiently taking away the heat in the condenser 302. This liquid cooling circulation system greatly improves the heat dissipation performance of the micro-arc oxidation power supply, and is particularly suitable for high-power and long-term continuous operation occasions. It can effectively suppress the internal temperature rise of the power supply, ensure the stable operation of the power supply equipment, extend its service life, and is conducive to improving the quality and efficiency of the micro-arc oxidation treatment.

[0031] Furthermore, a protective door 7 is movably connected to the front side of the box body 101 . The protective door 7 includes a door panel 701 . A control panel 702 is fixedly connected to the front side of the door panel 701 .

[0032] The protective door 7 is provided mainly to facilitate the operator to safely and conveniently access and maintain the battery body 2 and other electronic components inside the micro-arc oxidation power supply. The control panel 702 fixedly connected to the door panel 701 concentrates various control functions and display information of the power supply, such as power on / off, voltage and current adjustment, working mode switching, fault alarm prompts, etc. This design not only enhances the safety of the equipment and avoids non-professionals from accidentally touching the internal components, but also facilitates the operator to intuitively monitor the operating status of the power supply and make necessary parameter adjustments and maintenance operations at any time.

[0033] Furthermore, a handle 703 and a safety lock 704 are fixedly connected to the front side of the door panel 701 .

[0034] The handle 703 is provided to facilitate the operator to easily open and close the protective door 7 for daily inspection, maintenance or quick response in emergency situations. With the handle 703, the operator can easily operate the protective door 7 without the aid of other tools, thereby improving the convenience of use. The existence of the safety lock 704 means that only authorized personnel can open the protective door 7 by unlocking it, which greatly improves the safety level of the equipment, ensures the personal safety of the operator and the stable and reliable operation of the micro-arc oxidation power supply.

[0035] Furthermore, the box body 101 and the door panel 701 are both made of stainless steel.

It can effectively resist the erosion of the box body 101 and the door panel 701 by electrolytes or other possible corrosive media.
