Description

Technical Field

[0001] This utility model relates to the field of energy storage converter technology, specifically to a hybrid heat dissipation energy storage converter. Background Technology

[0002] A power storage converter (PCS) controls the charging and discharging process of a battery, converting AC to DC power, and can directly supply power to AC loads in the absence of a power grid. A PCS consists of a DC / AC bidirectional converter, a control unit, etc. The PCS controller receives control commands from the backend via communication and controls the converter to charge or discharge the battery according to the sign and magnitude of the power command, thereby regulating the active and reactive power of the power grid.

[0003] During long-term operation, the internal components of the energy storage converter will continuously generate heat. The main internal components that generate heat during continuous operation include the transformer and the power supply module. If the transformer and the power supply module cannot be effectively cooled, the continuous rise in temperature will affect the working efficiency of the transformer and the power supply module, and may even damage them.

[0004] Existing energy storage converters typically employ localized heat dissipation structures, such as water cooling or air cooling, near the transformer or power supply module to rapidly dissipate heat from relevant heat-generating components. However, due to the compact internal space of energy storage converters, heat dissipation is not ideal, easily leading to heat accumulation within the cabinet. This prevents rapid heat exchange with the external environment, affecting normal operation. Summary of the Invention

[0005] The purpose of this invention is to provide a hybrid heat dissipation energy storage converter to solve the problem of poor heat dissipation efficiency caused by the compact space in the prior art.

[0006] To solve the above problems, the hybrid heat dissipation energy storage converter involved in this utility model adopts the following technical solution:

[0007] A hybrid heat dissipation energy storage converter includes a cabinet and electrical components arranged inside the cabinet. The cabinet is formed by four side panels and two end panels. At least one end panel has an opening and closing structure to connect the interior of the cabinet with the outside. An air-cooled heat dissipation unit is provided inside the cabinet near the corresponding end panel. The air-cooled heat dissipation unit includes a mounting bracket arranged on the side near the corresponding end panel, and a cooling fan is arranged on the mounting bracket. A through opening is arranged on the end panel. The opening and closing structure includes an opening and closing plate that blocks the through opening, and a drive mechanism for driving the opening and closing plate to open and close.

[0008] Furthermore, there are two opening and closing structures, which are respectively arranged on the upper and lower end plates of the cabinet. The airflow direction of the corresponding two air-cooled heat dissipation units is consistent, so as to carry away the heat inside the cabinet.

[0009] Furthermore, the mounting bracket has several mounting ports, and there are multiple cooling fans, each corresponding to one of the mounting ports.

[0010] Furthermore, the mounting bracket is a plate-shaped structure, and a filter screen is arranged on the side of the mounting bracket corresponding to the fan.

[0011] Furthermore, there are multiple opening and closing plates arranged side by side in the through opening, with adjacent opening and closing plates staggered. Each opening and closing plate is rotatably assembled in the through opening, and a pull rope is connected to one side of each opening and closing plate. A torsion spring is connected between the opening and closing plate and the side wall of the through opening. The driving mechanism is integrally connected to each pull rope to drive the pull rope to pull the opening and closing plate to flip and open and close the through opening.

[0012] Furthermore, the driving mechanism includes a driving rod horizontally placed on the through opening, the moving direction of the driving rod being consistent with the arrangement direction of each opening and closing plate, and the driving mechanism also includes an electric push rod connected to the driving rod.

[0013] Furthermore, a reversing rod is provided on the side wall of the through opening, and the pull rope passes around the reversing rod and connects to the drive rod.

[0014] Furthermore, the airflow direction of both air-cooled heat dissipation units extends upwards.

[0015] The beneficial effects of this utility model are as follows: This hybrid heat dissipation energy storage converter makes reasonable use of the space near the two end plates inside the cabinet. During the heating process of the internal components, the air-cooled heat dissipation unit works in conjunction with the module's own heat dissipation structure to achieve a hybrid heat dissipation combining air cooling and water cooling, quickly dissipating the heat inside the cabinet to the outside, thus maintaining the same temperature between the inside and outside of the cabinet. Furthermore, the opening and closing structure at the through-hole can be selectively opened and closed according to actual heat dissipation needs, effectively preventing external dust and debris from entering the cabinet and causing contamination and damage to the components. It has a simple structure, excellent heat dissipation effect, and high heat dissipation efficiency. Attached Figure Description

Detailed Implementation

[0022] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Specific embodiments of the hybrid heat dissipation energy storage converter involved in this utility model are as follows: Figures 1 to 4 As shown, the hybrid heat dissipation energy storage converter includes a cabinet 1 and electrical components arranged inside the cabinet 1. The cabinet 1 is formed by surrounding side plates 3 and upper and lower end plates 2. The electrical components are basically the same as those of existing energy storage converters, including transformers and corresponding power supply modules. Water-cooled and air-cooled heat dissipation structures are arranged on each heat-generating electrical component to dissipate heat from specific heat-generating electrical components.

[0024] Both end plates 2 are equipped with opening and closing structures 4, which connect the interior of the cabinet 1 to the outside, facilitating the outflow of internal gas and the entry of outside air into the cabinet 1 for heat exchange. Specifically, a through-hole 5 is arranged on the end plate 2 of the cabinet 1. The opening and closing structure 4 includes an opening and closing plate 6 that is positioned on the through-hole 5, and a drive mechanism that drives the opening and closing plate 6 to open and close. The drive mechanism moves the opening and closing plate 6, thereby opening and closing the through-hole 5 to control the position of the end plate 2.

[0025] Preferably, there are multiple opening and closing plates 6 arranged side by side within the through opening 5, with adjacent opening and closing plates 6 staggered. Each opening and closing plate 6 is rotatably assembled within the through opening 5. A pull rope 8 is connected to one side of each opening and closing plate 6, and a torsion spring is connected between the opening and closing plate 6 and the side wall of the through opening 5. The drive mechanism is integrally connected to each pull rope 8 to drive the pull rope 8 to pull the opening and closing plate 6 to flip and open and close the through opening 5. The drive mechanism includes a drive rod 7 horizontally placed on the through opening 5, and the direction of movement of the drive rod 7 is consistent with the arrangement direction of each opening and closing plate 6. The drive mechanism also includes an electric push rod 10 connected to the drive rod 7.

[0026] In the actual opening and closing control process, the control module controls the electric push rod 10 to move, driving the drive rod 7 to move horizontally, thereby pulling the pull rope 8. The pull rope 8 causes the opening and closing plates 6 to flip in the same direction, thus opening the through-hole 5 and realizing internal and external passage. When it is necessary to close the through-hole 5, the electric push rod 10 returns to its original position, and the torsion spring causes the opening and closing plates 6 to flip in the opposite direction. The through-hole 5 is closed by the staggered arrangement of the various opening and closing plates 6. In order to ensure synchronous driving of each opening and closing plate 6, a reversing rod 9 is also provided on the side wall of the through-hole 5. The pull rope 8 passes around the reversing rod 9 and connects to the drive rod 7. The lengths of the pull ropes 8 are consistent, the reversing positions are arranged at the same height, and the connection positions of each pull rope 8 and each opening and closing plate 6 are also consistent, thereby ensuring synchronous control.

[0027] The cabinet 1 described above is equipped with air-cooled heat dissipation units near the corresponding two end plates 2. Each air-cooled heat dissipation unit includes a mounting bracket 12 arranged on one side near the corresponding end plate 2, and a cooling fan 11 is arranged on the mounting bracket 12. The two opening and closing structures 4 described above are respectively arranged on the upper and lower end plates 2 of the cabinet 1. The airflow direction of the two corresponding air-cooled heat dissipation units is the same to carry away the heat inside the cabinet 1. In this embodiment, in order to meet the requirements of rapid heat dissipation and to prevent dust and debris from falling into the through opening 5, the airflow direction of the two air-cooled heat dissipation units is arranged to extend upwards.

[0028] When internal heat accumulates, the temperature sensor detects excessive internal heat. The control module then activates the fan and simultaneously controls the electric push rod 10 to open the opening and closing mechanisms 4 on both sides. The bottom cooling fan 11 then blows cool outside air into the cabinet 1, where it undergoes rapid heat exchange with electrical components. The heat-exchanged air is then exhausted to the outside by the top cooling fan 11. This effectively increases the airflow rate and heat exchange rate of cool outside air within the cabinet 1, thus significantly improving heat dissipation efficiency.

[0029] To ensure effective heat exchange at all locations within the cabinet 1, the mounting bracket 12 has several mounting ports, and multiple cooling fans 11 are installed in each port, ensuring that cool air can pass through all horizontal locations within the cabinet 1 for heat exchange. To facilitate the installation of the cooling fans 11 and prevent external dust accumulation, the mounting bracket 12 has a plate-like structure, and a filter screen 13 is arranged on the side of the mounting bracket 12 corresponding to the fan.

[0030] In actual use, the air-cooled heat dissipation units on the two end plates 2, combined with the heat dissipation structure of the electrical components themselves, can quickly and effectively dissipate heat inside the cabinet 1, resulting in good heat dissipation effect and high heat dissipation efficiency.

[0031] In other embodiments, the opening and closing structure 4 may also adopt a structure similar to an electric louver window.

[0032] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
