Description

Technical Field

[0001] The utility model relates to a ventilation and heat dissipation structure of an energy storage, boost and current conversion integrated machine. Background Art

[0002] The existing air duct design for ventilation and heat dissipation of energy storage boost converters is almost always to install one or more heat dissipation axial flow fans on the top or side of the cabinet, and use strong exhaust to remove the heat. It almost still follows the traditional fixed way of thinking. This method has poor heat dissipation effect and extremely high noise. The design of the circulating air duct is almost not considered. The operation guarantee of the internal equipment of the energy storage boost converter is poor, affecting its work efficiency. It cannot effectively remove the high temperature generated by the internal equipment during operation, which may affect the normal operation of the energy storage boost converter, and even cause failures, thus affecting the normal operation of the energy storage power station.

[0009] Figure 1 The utility model is a schematic diagram of the ventilation and heat dissipation structure of an energy storage, boost and converter integrated machine. DETAILED DESCRIPTION

[0010] The technical solution of the utility model is further explained below in conjunction with the accompanying drawings.

[0011] like Figure 1 As shown, a ventilation and heat dissipation structure of an energy storage boost converter integrated machine of the utility model comprises two energy storage converters 1 and an energy storage container 2 arranged adjacent to the energy storage converter 1, and a wiring conduit 3 is arranged between the energy storage converter and the energy storage container; the energy storage converter 1 comprises a cabinet and a power unit module and a reactor arranged in the cabinet, the power unit module is arranged at the upper part of the cabinet, and the reactor is arranged at the lower part of the cabinet;

[0012] A main air duct outlet 5 is provided at the top of the side of the energy storage converter adjacent to the energy storage container, and a main air duct inlet is provided at the top of the side opposite to the energy storage container (not shown in the figure due to visual obstruction, and its position corresponds to the air outlet), and a centrifugal fan is installed at the main air duct inlet position;

[0013] A bracket 4 is provided at the bottom of the energy storage converter, and the energy storage converter 1 is lifted by the bracket 4, and at the same time, the bottom of the reactor in the cabinet is also lifted by the bracket; an air inlet of the reactor air duct is provided on the bottom surface of the energy storage converter cabinet (not shown in the figure due to visual obstruction), and an air outlet 6 of the reactor air duct is provided in the middle of the side of the energy storage converter adjacent to the energy storage container, and the air outlet (6) of the reactor air duct is located at the top of the reactor; an axial flow fan is vertically installed at the air inlet of the reactor air duct, and an axial flow fan is horizontally installed at the air outlet of the reactor air duct;

[0014] The energy storage container includes a transformer compartment and a low-voltage compartment placed side by side; a transformer compartment air duct air inlet 7 is provided at the bottom of the compartment door of the transformer compartment, and a transformer compartment air duct air outlet 8 is provided at the top of the compartment door of the transformer compartment; a low-pressure compartment air duct air inlet 9 is provided at the bottom of the compartment door of the low-pressure compartment, and a low-pressure compartment air duct air outlet 10 is provided at the top of the compartment door of the low-pressure compartment.

[0015] Main air duct of the inverter: Air inlets and outlets are designed at the front and back of the top of the inverter to form a horizontal air duct, which can discharge most of the heat generated by the inverter. A high-power centrifugal fan is designed and installed on the top to quickly take away the heat generated by the normal operation of the cabinet.

[0016] Converter reactor air duct: An air duct designed for the vertical direction of the converter reactor. The air inlet of the air duct is set on the bottom surface of the converter at a position corresponding to the reactor. The area of ​​the air inlet can also be larger than the reactor. At the same time, the bottom of the reactor is also raised by the bracket. After the cold air enters the converter, it is dispersed to all sides of the reactor. Compared with the traditional converter side air inlet, the contact area between the cold air and the reactor can be greatly increased, and the heat generated by the converter reactor during operation can be quickly taken away in a horizontal manner. The reactor air duct outlet will be designed at the position of the reactor in the middle of the energy storage converter. The bottom of the energy storage converter is raised by a bracket, and the bottom air inlet is designed to allow the bottom cold air to flow up to the position of the middle reactor for cooling and heat dissipation. An axial flow fan is installed vertically at the reactor air duct inlet, and an axial flow fan is installed horizontally at the reactor air duct outlet. The reactor air duct outlet is designed on the back of the middle position of the energy storage converter to take away the heat of the reactor. The above-mentioned way of designing the air duct conforms to the principles of aerodynamics. The density of cold air at the bottom is generally larger, and the density of hot air is smaller. The cold air is transported upward and the hot air is discharged out of the cabinet. The fan selected in this way is an axial flow fan, which has low noise and good heat dissipation effect, thereby improving the efficiency of heat dissipation. In the energy storage converter, the reactor and the power unit module are the devices that generate the most heat. The utility model arranges an air outlet at the position of the reactor to quickly take away the heat generated by the reactor, and the part that is not completely dissipated can also be discharged again through the main air duct outlet on the top, thereby achieving the purpose of further heat dissipation and exhaust.

[0017] Transformer compartment air duct: The vertical air duct designed for the low-voltage control part inside the energy storage boost converter can quickly remove the heat generated inside the low-voltage compartment during operation. The air inlet at the bottom of the compartment door is designed, and the air outlet is designed at the top side to remove the high temperature generated inside during operation.

[0018] Low-voltage warehouse air duct: The vertical air duct designed for the boost transformer part of the energy storage boost converter can quickly remove the heat generated by the boost transformer during operation. The air inlet at the bottom of the warehouse door is designed, and the air outlet is designed at the top side to remove the high temperature generated during internal operation.
