Description

Technical Field

[0001] This utility model relates to the field of inverter power supply technology, and in particular to a multi-layer structure inverter power supply. Background Technology

[0002] A vehicle inverter is a convenient power conversion device for vehicles that converts the direct current (DC) from the car engine or battery into alternating current (AC) for use by general electrical products.

[0003] Currently, existing vehicle-mounted inverter power supplies have the following defects: (1) They are single-layer inverter power supply structures, occupy a large area, do not make full use of the height space inside the box, have a single size, and are difficult to adapt to different installation environments; (2) The DC / DC converter and inverter share a circuit board, which makes the installation of the DC / DC converter and inverter less flexible; (3) They have poor electromagnetic compatibility and heat dissipation characteristics, which leads to unstable working performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a multi-layer inverter power supply with simple structural design, multi-layer assembly, utilization of the height space inside the box, adaptability to different installation environments, flexible installation, good electromagnetic compatibility and heat dissipation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-layer structure inverter power supply, including a cabinet and a reverse connection protection module, a filter module, a DC / DC converter, an inverter and a control module disposed in the cabinet. The reverse connection protection module and the filter module are arranged in parallel and are located in front of the inverter. The DC / DC converter is mounted on the inverter and the control module is mounted on the reverse connection protection module. The reverse connection protection module, the filter module, the DC / DC converter and the inverter are connected in sequence. The control module is connected to the reverse connection protection module, the DC / DC converter and the inverter respectively.

[0006] Furthermore, air vents are provided at both the left and right ends of the DC / DC converter and inverter.

[0007] Furthermore, several ventilation holes are respectively provided on the left and right side panels of the box body.

[0008] Furthermore, handles are provided at both ends of the front panel of the box.

[0009] The beneficial effects of the utility model are:

[0010] (1) The DC / DC converter and inverter in this utility model adopt a two-layer installation design, which realizes the two-layer installation structure, reduces the floor area, makes use of the height space inside the box, and facilitates the installation of the inverter power supply, so as to adapt to different installation environments; combined with the setting of the filter module, the capacitor compatibility performance of the inverter power supply is improved.

[0011] (2) In this utility model, the DC / DC converter and the inverter are set up independently and controlled by two circuit boards respectively, which makes the installation of the DC / DC converter and the inverter more flexible.

[0012] (3) The air vent in this utility model improves the heat dissipation capacity of the DC / DC converter and inverter, which can meet the requirements of use in high temperature environment, thereby ensuring the working performance of the DC / DC converter and inverter.

[0020] Example 1

[0021] like Figure 1-Figure 4As shown, a multi-layer inverter power supply includes a housing 100 and a reverse connection protection module 200, a filter module 300, a DC / DC converter 400, an inverter 500, and a control module 600 disposed within the housing 100. The reverse connection protection module 200 and the filter module 300 are arranged side by side and are positioned in front of the inverter 500. The DC / DC converter 400 is mounted on the inverter 500, and the control module 600 is mounted on the reverse connection protection module 200. The reverse connection protection module 200, the filter module 300, the DC / DC converter 400, and the inverter 500 are connected in sequence, and the control module 600 is connected to the reverse connection protection module 200, the DC / DC converter 400, and the inverter 500 respectively. The DC / DC converter 400 and inverter 500 adopt a two-layer installation design, reducing the footprint and utilizing the internal height space of the enclosure 100. This also facilitates the installation of the inverter power supply, making it adaptable to different installation environments. Combined with the filter module 300, the capacitor compatibility of the inverter power supply is improved. The DC / DC converter 400 and inverter 500 are independently configured and controlled by two separate circuit boards, making their installation more flexible. Specifically, the left and right side panels of the enclosure 100 have several ventilation holes 110 to release internal heat; the left and right ends of the front panel of the enclosure 100 have handles 700 for easy movement of the entire power supply; the casings of both the DC / DC converter 400 and inverter 500 are shielded with stainless steel, and other components also use fully enclosed casings, further improving the capacitor compatibility of the inverter power supply.

[0022] like Figure 3 As shown, to improve the heat dissipation capacity of the DC / DC converter 400 and inverter 500, vents 410 are provided at both ends of the DC / DC converter 400 and inverter 500, enabling them to operate in high-temperature environments and thus ensuring their performance. Specifically, there are two vents 410 at each end.
