Description

Technical Field

[0001] This utility model relates to the field of power module technology, specifically to an installation structure for a power management module of an underwater power supply system. Background Technology

[0002] Modular power supplies are power supplies that can be directly mounted on printed circuit boards to provide power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads. These modules are called point-of-load (POW) power supplies or point-of-use (POU) power supplies. Due to the significant advantages of their modular structure, modular power supplies are widely used in communication fields such as switching equipment, access equipment, mobile communications, microwave communications, optical transmission, and routers, as well as in automotive electronics, aerospace, and other industries.

[0003] The heat dissipation of the power management module of the existing underwater power supply equipment can only meet the power requirements of voltage conversion below 600V DC. For high-voltage 900VDC high-power 15kKW power supplies, the heat generated by the power supply is large. If heat dissipation is not carried out in time, the temperature inside the tank will rise, thereby affecting the working efficiency of the circuit components inside the tank.

[0004] Therefore, it is necessary to design a power management module installation structure for an underwater power supply system that can improve the above-mentioned problems. Summary of the Invention

[0005] To address the problems of existing technologies, this utility model provides a power management module installation structure for an underwater power supply system, including an outer cylinder. An installation frame is provided inside the outer cylinder. The installation frame includes a plurality of partitions arranged horizontally and parallel from bottom to top. A first windbreak guide plate is vertically arranged between each pair of adjacent partitions. The top of the partition is connected to the bottom of the first windbreak guide plate. A second windbreak guide plate is also installed at the bottom of the outer cylinder. The second windbreak guide plate has a guide opening groove.

[0006] The first windbreak guide plate has a power supply function unit on one side, and the power supply function unit is installed on the baffle. The baffle has several heat conduction holes, and several support columns are circumferentially connected to the baffle. The baffle is perpendicular to the support columns.

[0007] A blower fan is provided on one side surface of the outer cylinder, located at the top of the area enclosed by the outer cylinder and one side of the first air-blocking guide plate along the length direction. A heat dissipation hole is provided on the outer cylinder at the position of the blower fan, and the air outlet of the blower fan faces the exhaust hole. An exhaust fan is provided on the other side surface of the outer cylinder, located at the top of the area enclosed by the outer cylinder and the other side of the first air-blocking guide plate along the length direction. An exhaust hole is provided on the outer cylinder at the position of the exhaust fan, and the air outlet of the exhaust fan faces the heat dissipation hole.

[0008] Furthermore, the partition is disc-shaped, and the support pillars include 12 pillars, which are evenly distributed around the partition.

[0009] Furthermore, the outer cylinder, partition, and support are all made of hard aluminum alloy.

[0010] Furthermore, the outer cylinder includes a bottom mounting plate, a top cover plate, and a cylinder body. The mounting bracket is disposed inside the cylinder body. The top cover plate is disposed at the top of the cylinder body, and the bottom mounting plate is disposed at the bottom of the cylinder body. The top cover plate, the cylinder body, and the bottom mounting plate are connected by several pillars to form an integral structure.

[0011] Furthermore, a one-way airflow guiding structure is installed in the airflow guiding opening groove to guide the airflow from the area enclosed by the outer cylinder and one side of the first windproof guide plate to the area enclosed by the outer cylinder and the other side of the first windproof guide plate;

[0012] Furthermore, a circuit board is provided at one end of the upper cover plate near the air blower. The circuit board is located on one side of the power multifunction unit, and the side of the circuit board is attached to one end of the upper cover plate.

[0013] Furthermore, the unidirectional flow structure is a Tesla unidirectional flow structure;

[0014] Furthermore, the top of the upper cover plate is equipped with symmetrically arranged foldable handles;

[0015] The beneficial effects of this utility model are:

[0016] The power management module installation structure of this utility model includes an outer cylinder, inside which is a mounting frame. The mounting frame includes several partitions arranged horizontally and parallel from bottom to top. A first air-blocking guide plate is vertically arranged between each pair of adjacent partitions. The top of the partition is connected to the bottom of the first air-blocking guide plate. Several support columns are also circumferentially connected to the partitions. The partitions and the support columns are arranged perpendicularly to each other. When airflow passes through the area enclosed by the outer cylinder and one side of the first air-blocking guide plate, the heat generated by the power function unit on each partition can be carried away through the heat-conducting holes. Thus, when a high-voltage, high-power power supply is placed inside the outer cylinder, the power supply can have a large heat dissipation efficiency. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-4This utility model provides a power management module installation structure for an underwater power supply system, including an outer cylinder 1. An installation frame 2 is provided inside the outer cylinder 1. The installation frame 2 includes multiple horizontally and parallel partitions 21 arranged sequentially from bottom to top. A first wind-blocking guide plate 22 is vertically arranged between adjacent partitions 21. The top of each partition 21 is connected to the bottom of the first wind-blocking guide plate 22. A second wind-blocking guide plate is also installed at the bottom of the outer cylinder 1. The second wind-blocking guide plate has a guide opening groove for guiding cold air from one side of the top layer of the outer cylinder 1 to the bottom layer via a blower fan 3, and then returning to the top layer from the other side of the outer cylinder 1. Heat is then carried away by an exhaust fan 4. The first wind-blocking guide plate 22 is an L-shaped baffle, and the second wind-blocking guide plate is also an L-shaped baffle with a guide opening groove.

[0025] A power supply unit is provided on one side of the first air-insulating baffle 22, and the power supply unit is mounted on the baffle 21. The baffle 21 is provided with several heat-conducting holes, and several support columns 23 are circumferentially connected to the baffle 21. The baffle and the support columns 23 are arranged perpendicularly to each other. When airflow passes through the area enclosed by the outer cylinder 1 and one side of the first air-insulating baffle 22, the heat generated by the power supply unit on each baffle 21 can be carried away through the heat-conducting holes. Thus, when a high-voltage (900VDC) high-power (15kKW) power supply is placed inside the outer cylinder 1, the power supply can have a large heat dissipation efficiency.

[0026] A blower fan 3 is provided on one inner surface of the outer cylinder 1. The blower fan 3 is located at the top of the area enclosed by the outer cylinder 1 and the first air-blocking guide plate 22 along the length direction. A heat dissipation hole is provided on the outer cylinder 1 at the position of the blower fan 3, and the air outlet of the blower fan 3 faces the exhaust hole. A ventilation fan 4 is provided on the other inner surface of the outer cylinder 1. The ventilation fan 4 is located at the top of the area enclosed by the outer cylinder 1 and the first air-blocking guide plate 22 along the length direction. A ventilation hole is provided on the outer cylinder 1 at the position of the ventilation fan 4, and the air outlet of the ventilation fan 4 faces the heat dissipation hole.

[0027] It should be noted that the mounting frame 2 adopts a four-layer unit integrated architecture consisting of three-layer partitions 21 and support columns 23. The power conversion unit is installed on the bottom mounting plate 13, the power rectification and filtering unit is installed on the second partition 21, the power PWM control unit is installed on the third partition 21, the power input, output filtering and protection control unit is installed on the fourth partition 21, and the power input and output electrical connections are installed on the top cover plate 12. The four-layer functional unit integrated architecture enables the power management module to complete the high-voltage 900VDC-15kW power conversion within a volume of 320mm in diameter and 389mm in height.

[0028] Furthermore, the partition is disc-shaped, and the support columns include 12 support columns 23. The partition 21 is also circumferentially connected with 12 support columns 23. The included angle between two adjacent support columns 23 is set to 60°. The mounting frame is divided by the support columns 23 at 60°. The 12 support columns 23 connect the four functional units of the power management module and the upper cover plate 12 to form an integral structure, ensuring that the power management module meets the usage requirements of the underwater power supply system.

[0029] Furthermore, the outer cylinder 1 includes a bottom mounting plate 13, an upper cover plate 12, and a cylinder body 11. The mounting bracket 3 is disposed inside the cylinder body 11. The upper cover plate is disposed on the top of the cylinder body 11, and the bottom mounting plate is disposed on the bottom of the cylinder body 11. The upper cover plate 12, the cylinder body 11, and the bottom mounting plate 13 are connected by several support columns 23 to form an integral structure; this is used to ensure that the power management module meets the requirements of the operating environment.

[0030] Furthermore, a one-way airflow guiding structure 5 is installed in the airflow guiding opening groove to guide the airflow from the area enclosed by the outer cylinder 1 and the first air-insulating guide plate 22 on one side to the area enclosed by the outer cylinder 1 and the first air-insulating guide plate 22 on the other side.

[0031] The heat-conducting through-hole on the partition 21 near the bottom mounting plate 13 is located directly above the ventilation hole, which facilitates the dissipation of heat through the ventilation hole;

[0032] Furthermore, a circuit board is provided at one end of the upper cover plate 12 near the air supply fan 3. The circuit board is located on one side of the power multifunction unit, and the side of the circuit board is in contact with one end of the upper cover plate 12. When the airflow enters the outer cylinder 1, it can prevent the airflow from directly flowing out from the heat dissipation fan near the power multifunction unit, thereby increasing the heat carried away by the airflow.

[0033] like Figure 4 As shown, the unidirectional flow structure 5 is a Tesla unidirectional flow structure;

[0034] Furthermore, the outer cylinder 1, partition 21, and support column 23 are all made of hard aluminum alloy, which facilitates heat conduction. Furthermore, the top of the upper cover plate 12 is equipped with symmetrically arranged foldable handles, ensuring that the power management module can be quickly installed, removed, and moved.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
