Description

Technical Field

[0001] This application relates to the field of energy storage converter equipment, and in particular to a heat dissipation structure for an energy storage converter. Background Technology

[0002] Energy storage converters are key components in energy storage systems, used to convert direct current (DC) from batteries to alternating current (AC), or alternating current from the grid to DC, to facilitate battery charging and discharging. Energy storage converters play a vital role in renewable energy systems, microgrids, electric vehicle charging stations, and industrial energy storage applications.

[0003] Most existing energy storage converter housings are equipped with fans and are split-type. In actual equipment installation, the assembly process is relatively complicated, requiring individual positioning and fixation. With gaps between the housings, the thermal resistance is high, the heat dissipation effect is poor, and it cannot take care of most of the heat-generating components that need heat dissipation. Utility Model Content

[0004] To facilitate unified heat dissipation for most heat-generating components, this application provides a heat dissipation structure for an energy storage converter.

[0005] The heat dissipation structure for an energy storage converter provided in this application adopts the following technical solution:

[0006] A heat dissipation structure for an energy storage converter includes a housing body, a top cover plate, and an integrated base. The integrated base is installed inside the housing body and has a cavity inside. A heat dissipation device for dissipating heat from electronic components is installed in the cavity. An inverter inductor slot, a grid-side inductor slot, and a filter capacitor slot are integrally formed on the upper surface of the integrated base. The top cover plate is installed on the housing body and can cover the electronic components installed inside the integrated base.

[0007] By adopting the above technical solution, inverter inductor slots, grid-side inductor slots, and filter capacitor slots are opened on the integrated base. Electronic components are installed through the inverter inductor slots, grid-side inductor slots, and filter capacitor slots. A heat dissipation device is set inside the integrated base, so that various electronic components can be integrated and installed, and it is convenient to uniformly dissipate heat from most heat-generating components.

[0008] In one specific implementation scheme, the inverter inductor slot, the grid-side inductor slot, and the filter capacitor slot are sequentially formed on the upper end face of the integrated base.

[0009] By adopting the above technical solution, the inverter inductor slot, the grid-side inductor slot, and the filter capacitor slot are sequentially opened on the upper end face of the integrated base, which allows the various electronic components to be arranged in a reasonable manner, effectively reducing the space occupied inside the housing, improving heat dissipation efficiency and overall structural compactness.

[0010] In one specific implementation, the heat dissipation device includes a water inlet, a water outlet, and a heat pipe. The water inlet and the water outlet are both installed on the side wall of the integrated base and connected to the cavity. The heat pipe is installed inside the cavity, with one end of the heat pipe connected to the water inlet and the other end of the heat pipe connected to the water outlet.

[0011] By adopting the above technical solution, the heat dissipation device includes a water inlet, a water outlet, and a heat pipe. The water inlet and water outlet are installed on the side wall of the integrated base and connected to the cavity. The heat pipe is installed in the cavity and connected to the water inlet and water outlet, thereby achieving efficient liquid cooling and improving the overall cooling effect.

[0012] In one specific implementation, the heat pipe is arranged in a U-shape within the cavity.

[0013] By adopting the above technical solution, the heat pipe is arranged in a U-shape in the cavity, which increases the contact area between the heat pipe and the air in the cavity, improves the heat dissipation efficiency, and further optimizes the cooling effect of the overall heat dissipation structure.

[0014] In one specific implementation, at least three grid-side inductor slots are provided and arranged side by side, and the grid-side inductor slots are configured as semi-circular slots.

[0015] By adopting the above technical solution, at least three grid-side inductor slots are arranged side by side, and these slots are designed as semi-circular slots. This achieves effective component placement and heat dissipation, improving the space utilization and heat dissipation efficiency of the heat dissipation structure.

[0016] In one specific implementation, at least three filter capacitor slots are provided and arranged side by side, and the filter capacitor slots are configured as rectangular slots.

[0017] By adopting the above technical solution, at least three filter capacitor slots are set and arranged side by side. The filter capacitor slots are set as rectangular slots, which allows the filter capacitors to be arranged more closely, reducing the space occupied inside the housing and improving the space utilization rate. At the same time, the semi-circular slot design helps to improve the heat dissipation effect.

[0018] In one specific implementation, at least three inverter inductor slots are provided and arranged side by side, and the inverter inductor slots are rectangular slots.

[0019] By adopting the above technical solution, at least three inverter inductor slots are set up side by side. The inverter inductor slots are set as rectangular slots, which makes the installation of inverter inductors more stable, improves heat dissipation efficiency, and facilitates the compact layout of the overall structure.

[0020] In one specific implementation, the integrated base is provided with a plurality of positioning tubes, and the inner sidewall of the positioning tubes is provided with internal threads. The integrated base is fixedly connected to the cover plate by screws passing through the cover plate and connecting to the positioning tubes.

[0021] By adopting the above technical solution, the fixed connection between the integrated base and the upper cover plate is more stable, simplifying the assembly process and improving assembly efficiency. The positioning tube allows the screws to be accurately connected to the cover plate, ensuring the stability of the overall structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The integrated mounting base has inverter inductor slots, grid-side inductor slots, and filter capacitor slots. Electronic components are installed through these slots. A heat dissipation device is installed inside the integrated mounting base, which enables the integrated installation of various electronic components and facilitates unified heat dissipation for most heat-generating components.

[0024] 2. The inverter inductor slot, the grid-side inductor slot, and the filter capacitor slot are sequentially located on the upper surface of the integrated base, which allows for the rational layout of various electronic components, effectively reduces the space occupied inside the housing, and improves heat dissipation efficiency and overall structural compactness.

[0025] 3. The heat pipes are arranged in a U-shape inside the cavity, which increases the contact area between the heat pipes and the air inside the cavity, improves heat dissipation efficiency, and further optimizes the cooling effect of the overall heat dissipation structure.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] This application discloses a heat dissipation structure for an energy storage converter.

[0033] like Figure 1 As shown, the heat dissipation structure of the energy storage converter includes a housing body 1, a top cover plate 2, and an integrated base 3. The integrated base 3 is installed inside the housing body 1, and a cavity 31 is formed inside the integrated base 3. A heat dissipation device 4 for cooling electronic components is installed within the cavity 31. The upper surface of the integrated base 3 has an inverter inductor slot 32, a grid-side inductor slot 33, a relay slot, and a filter capacitor slot 34, all integrally formed. The top cover plate 2 is installed on the housing body 1 and can cover the electronic components installed inside the integrated base 3. This design achieves unified integrated heat dissipation, simplifies the assembly process, and improves heat dissipation performance.

[0034] like Figure 2 As shown, the inverter inductor slot 32 is a rectangular slot, the grid-side inductor slot 33 is configured with at least three slots arranged side by side, and the filter capacitor slot 34 is configured with at least three slots arranged side by side. The inverter inductor slot 32 adopts a rectangular design to facilitate the installation of the inverter inductor, the grid-side inductor slot 33 adopts a semi-circular slot design, and the filter capacitor slot 34 adopts an elliptical slot, which are arranged side by side in the slots. Several relays can be installed side by side on the upper surface of the integrated base 3 between the relay slot and the filter capacitor slot 34, thereby making the most of the space in the integrated base 3 to install more electronic components and uniformly dissipate heat from the electronic components.

[0035] like Figure 4 As shown, the integrated base 3 is also equipped with several positioning tubes 5. The inner wall of the positioning tubes 5 is provided with internal threads. The positioning tubes 5 are connected to the cover plate by screws passing through them, thereby fixing the integrated base 3 to the cover plate. The positioning tubes 5 are made of high-strength threaded tubes and stainless steel. The internal thread diameter and wall thickness are the same.

[0036] like Figure 3 and Figure 4As shown, the cooling structure includes an inlet nozzle 41, an outlet nozzle 42, and a heat pipe 43. The inlet nozzle 41 and outlet nozzle 42 are mounted on the side wall of the integrated base 3 and connected to the cavity 31. The heat pipe 43 is installed inside the cavity 31, with one end connected to the inlet nozzle 41 and the other end connected to the outlet nozzle 42. Specifically, the inlet nozzle 41 and outlet nozzle 42 are installed in parallel to ensure uniform water flow. The inlet nozzle 41 can be a stainless steel inlet nozzle with a valve design. The outlet nozzle 42 is also made of stainless steel but without a valve design.

[0037] The heat pipe 43 is specifically arranged in a U-shape within the cavity 31 to enhance heat flow and heat dissipation uniformity. The heat pipe 43 is composed of multiple straight and bent pipe sections, and is fixed to the integrated base 3 by welding to ensure structural stability and sealing.

[0038] The implementation principle of the heat dissipation structure of the energy storage converter in this application embodiment is as follows: the inverter inductor, filter capacitor, and grid-side inductor are respectively installed in the inverter inductor slot 32, filter capacitor slot 34, and grid-side inductor slot 33. Several relays can be installed side by side on the upper surface of the integrated base 3 between the relay slot and the filter capacitor slot 34. The upper cover plate 2 is installed on the housing body 1 and connected to the positioning tube 5 by screws through the cover plate, thereby fixing the integrated base 3 to the cover plate. Coolant is then introduced into the water inlet 41. The coolant is discharged from the water outlet 42 after passing through the U-shaped heat conduction pipe 43. The U-shaped heat conduction pipe 43 increases the contact area between the heat conduction pipe 43 and the air in the cavity 31, improves the heat dissipation efficiency, and further optimizes the cooling effect of the overall heat dissipation structure. Moreover, the integrated base 3 enables the integrated installation of various electronic components, which facilitates the unified heat dissipation treatment of most heat-generating components.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
