Electrical box, outdoor unit, photovoltaic conditioning system and electrical appliance

Abstract

The invention provides an electrical box, an outdoor unit, a photovoltaic conditioning system and an electrical appliance. The electrical box comprises a housing; a heating area is formed in the housing. The electrical box, the outdoor unit, the photovoltaic conditioning system and the electrical appliance have the advantages that a condensing plate or a separator is provided, a condensing space is formed, negative pressure generated by a fan enables the electrical box to form condensation only in the condensing space, and the problems are effectively avoided that condensation in the electrical box causes short circuit and that condensation due to a reflow of cold air to the heating area upon loss of the negative pressure of the fan causes short circuit; a heat-dissipating structure can transfer heat in the electrical box into an air duct, the flow of air generated by the fan in the photovoltaic power generation mode is utilized to bring away the heat, and enhanced heat dissipation isprovided for the electrical box; an exhaust port, an intake port and an air outlet enable the negative pressure of the fan to form a flow of air in the electrical box in forced manner, and dissipationfor the heat in the electrical box is enhanced.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to an electrical box, an outdoor unit, a photovoltaic air-conditioning system and electrical equipment. Background technique [0002] Photovoltaic air conditioners, especially full DC photovoltaic air conditioners, use a large number of power devices (such as photovoltaic inverter grid-connected DC / AC modules, rectifier AC / DC modules, DC load power supply DC / DC modules, etc.), which require good space and The cooling channel is used to ensure the safe and reliable operation of the unit, but the side air outlet shell of the existing photovoltaic air conditioning system cannot meet the heat dissipation requirements and condensation will occur. Contents of the invention [0003] In order to solve the above-mentioned technical problems, an electrical box, an outdoor unit, a photovoltaic air-conditioning system, and electrical equipment that increase heat dissipation ef...
