Description

Technical Field

[0001] The invention relates to the field of converter heat dissipation structures, in particular to a converter ventilation structure. Background Art

[0002] The types of converters include: rectifier (AC to DC <ac dc>), inverter (DC to AC <dc ac>), AC converter (AC inverter <ac ac>) and DC converter (DC chopper <dcchopper>), wherein the photovoltaic inverter is a type of converter frequently used in the photovoltaic industry. In the prior art, in order to solve the problem that the temperature of the photovoltaic inverter is too high, the DC boost circuit is directly cut off, resulting in the photovoltaic inverter being unable to continue to supply power to the load, and the load is facing a sudden power outage.

[0003] A Chinese patent with publication number CN218006879U discloses a photovoltaic inverter, which has the function of enhancing the heat dissipation effect by turning on the cooling fan and the air outlet when the temperature of the photovoltaic inverter body reaches a preset value, so that the photovoltaic inverter body continues to operate to supply power to the load, thereby improving the user experience.

[0004] Although the above scheme realizes that the fan of the inverter body is turned on for heat dissipation when the temperature reaches the preset value, ensuring that the photovoltaic inverter body continues to operate to supply power to the load, the method of directly blowing air into the shell to dissipate heat for the photovoltaic inverter body through the cooling fan and flowing out of the shell through the air outlet does not effectively guide the airflow, and the airflow cannot effectively flow through the gap to cool down. In a high temperature environment, it cannot achieve a good heat dissipation effect, which can easily cause high temperature of internal components. Moreover, long-term heat dissipation will increase dust inside the body, increase the continuous working time of the cooling fan, and increase heat dissipation energy consumption.

The pump pipe can pump the water in the water tank to the outer cover. The air storage chamber is under the water tank. There are multiple air pipes, one end of which is fixed and connected to the air storage chamber, and the other end is fixed to the bottom surface of the water tank, and both are connected to the water tank. The air storage chamber is connected to the air outlet end of the blower assembly, one end of the bent pipe is fixed and connected to the upper end of the water tank, and the other end extends to the mounting plate. The liquid level in the water tank does not exceed the bent pipe. There are two circulation pipes, which are respectively installed at the upper and lower ends of the side wall of the water tank. The other end of the circulation pipe passes through the cabinet and is equipped with a valve.

[0009] Preferably, a water storage box is installed at the upper end of the outer cover corresponding to the dripping holes, the dripping holes are all in the water storage box, and one end of the pump tube away from the water tank is connected to the water storage box and communicated with the interior thereof.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The inverter ventilation structure is provided with a water-cooled dust reduction component. The fan pumps the external cold air into the air storage chamber, and enters the water tank along multiple air pipes. After being flushed by cold water at the bottom of the water tank, the air is transported to the mounting plate to cool the front and back of the mounting plate. The filter can reduce the amount of dust in the incoming air, and the dust particles contained in the air flowing through the water tank can be adsorbed by cold water, so that the air transported to the mounting plate carries less dust. During long-term blowing, dust is not easy to accumulate, which extends the service life of the equipment and improves the cooling effect.

[0017] 2. The inverter ventilation structure is provided with a heat exchange component. When the semiconductor refrigeration sheet takes effect, the cooling fins cool and the heat dissipating fins dissipate heat. The air in the cabinet that has absorbed the heat of the mounting plate will gradually heat up and then be discharged from the air duct to the outside. At this time, the discharged air can enhance the air flow at the position of the heat dissipating fins, which is used to cool the heat dissipating fins, and the cooling fins can cool the water droplets dripping from the water storage box. With the circulation of the pump pipe, the temperature of the water flow falling into the water tank will slowly decrease. Therefore, the external air will cool down after being flushed by the water flow in the water tank, which has a better cooling effect on the mounting plate.

[0018] 3. The inverter ventilation structure is provided with a mounting plate, a base and a guide groove. The base is used to install the inverter element. When installed in parallel, the heat will be concentrated on the protruding end, and the mounting plate will also heat up. The heat of the inverter element can also be transferred to the back of the mounting plate through the heat groove, thereby actively dissipating the heat and preventing the heat from being too concentrated. The curved pipes on the water tank correspond to the front and rear of the mounting plate respectively, and are used to cool the surrounding of the mounting plate, avoiding the existing problem of cooling only one side and causing the temperature of the other side to rise. In addition, the guide groove can increase the contact area between the airflow and the mounting plate, prolong the contact time, and improve the efficiency of heat exchange.

[0019] 4. The inverter ventilation structure is provided with air ducts and heat dissipation slots. The air ducts are attached to the rear of the cabinet. When the cabinet is installed, the heat can be dissipated to the ground at the rear without affecting the use of the adjacent cabinets. Moreover, the air ducts not only cool the heat dissipation fins through internal air outlet, but the heat dissipation slots themselves can also allow flowing air to pass through, thereby taking away the heat from the heat dissipation fins.

There are two circulation pipes 802, which are respectively installed at the upper and lower ends of the side wall of the water tank 801. The other end of the circulation pipe 802 passes through the cabinet 1 and is equipped with a valve.

[0039] The circulation pipe 802 is used to connect to an external water pipe. A water pipe can be set up outside to regularly circulate the cooling water in the water tank 801 to keep the cooling water inside clean. The external water pipe can be connected to the municipal tap water pipe. At the same time, a water pipe can be set up to connect multiple devices.

[0040] A water storage box 1007 is installed at the upper end of the outer cover 1005 corresponding to the drip hole 1006, and the drip holes 1006 are all in the water storage box 1007. The end of the pump tube 803 away from the water tank 801 is connected to the water storage box 1007 and communicated with the interior thereof.

[0041] When the water flow is concentrated inside the water storage box 1007, it will flow downward due to gravity.

[0042] There are two groups of curved pipes 804, each group has two curved pipes.

The fan 901 pumps the external cold air into the air storage chamber 805 and enters the water tank 801 along multiple air pipes 806. After being flushed by the cold water at the bottom of the water tank 801, it will slowly cool down, and the dust particles contained in the air flowing through the water tank 801 can be adsorbed by the cold water. The curved pipes 804 on the water tank 801 are respectively installed correspondingly. The front and rear of the plate 2 are used to cool down the surrounding area of ​​the mounting plate 2, avoiding the existing problem of cooling down only one side, causing the temperature of the other side to rise. In addition, the guide groove 5 can increase the contact area between the airflow and the mounting plate 2, prolong the contact time, and improve the efficiency of heat exchange. The air in the cabinet 1 that has absorbed the heat of the mounting plate 2 will gradually heat up and then be discharged from the air duct 7 to the outside. At this time, the discharged air can enhance the air flow at the position of the heat sink fins 1004, which is used to cool the heat sink fins 1004.
