Power conversion device and integrated machine

A cabinet air duct, a cabinet assembly and a photovoltaic inverter are provided according to the present application, where the cabinet air duct includes a cabinet and an air duct arranged in the cabinet. The cabinet is provided with an air inlet and an air outlet that are in communication with the air duct. The air inlet is arranged on a first side surface of the cabinet, the air outlet is arranged on a second side surface of the cabinet, and the first side surface and the second side surface are two opposite side surfaces of the cabinet.

Cabinet air duct, cabinet assembly and photovoltaic inverter

A heat dissipating system and a power cabinet are provided. The heat dissipating system includes a cabinet, a first circulating fan and a heat exchanger. The cabinet has an outer circulating air duct and a sealed inner circulating air duct. The air inlet and the air outlet connected to the outside are arranged in the outer circulating air duct, and the heat exchanger is arranged in the cabinet and configured to exchange heat between the inner circulating air duct and the outer circulating duct. The first circulating fan is arranged outside the air inlet of the outer circulating air duct or arranged inside the outer circulating air duct, and configured to supply air to the outer circulating air duct. The heat dissipation efficiency of the inner circulating air duct is improved.

Heat dissipating system and power cabinet

An outdoor cabinet and a top structure thereof are provided. The top structure of the outdoor cabinet includes a top beam, wherein the top beam is a bending plate; the number of the top beams is at least two, one of two connected top beams is provided with a first locating breach, and the other is provided with a first protruding portion in cooperation with the first locating breach for locating. Compared with that the top beam in the conventional art is a flat plate, the top structure of the outdoor cabinet provided effectively improves the strength of the top beam by designing the top beam to be the bending plate, which improves the strength of the overall top structure, reduces the influence on the hoisting of the outdoor cabinet, and improves the flexibility of the hoisting of the outdoor cabinet.

Outdoor cabinet and top structure thereof

An inverter power cabinet includes a cabinet body and power devices arranged in the cabinet body. The cabinet body includes a low-protection grade installation cavity and an airtight high-protection grade installation cavity hermetically isolated from each other; the power devices include high protection grade power devices arranged in the low-protection grade installation cavity and low-protection grade power devices arranged in the high-protection grade installation cavity; the low-protection grade installation cavity has an outer cold air inlet and an inner hot air outlet in communication with outside world, and a first fan is provided in the low-protection grade installation cavity; and the inverter power cabinet includes a heat exchanger configured to dissipate heat of the high-protection grade installation cavity. The inverter power cabinet can avoid direct contact of the low-protection grade power devices with a harsh environment, thereby preventing the contaminated cold air from damaging the low-protection grade power devices.
