Embodiment Construction
[0023] A method of circulating refrigeration in a charging pile, which uses a refrigeration device to generate a low-temperature cooling area inside the cabinet of the charging pile, heats and conducts heat outside the cabinet of the charging pile, and the energy is conserved, and the external fan (which can be the cooling device itself) external exhaust fan) to discharge the heat-conducting hot air from the cooling device to the outside of the cabinet to complete the heat exchange with the outside environment; ) pump the hot airflow generated by the heating module in the charging pile cabinet into the low-temperature cooling area, where the hot airflow is cooled in the low-temperature cooling area, realizing the heat exchange of cooling; the low-temperature cooling area recirculates and blows the low-temperature cold airflow into the heating module and In the area where the heating module is located, the hot air flow generated by the cold air flow flowing through the heating m...

The invention provides a method for internal circulation refrigeration of a charging pile. The method is characterized in that a low-temperature refrigeration area is generated inside a cabinet of thecharging pile through a refrigeration device, the outside of the cabinet of the charging pile is heated and conducted with heat, and hot air is exhausted from the cabinet to complete heat exchange with the external environment, hot air flow generated by a heating module in the cabinet of the charging pile is drawn into the low-temperature refrigeration area, low-temperature cold air flow is circularly blown into the heating module and an area where the heating module is located from the low-temperature refrigeration area, and hot air flow generated by the cold air flow flowing through the heating module and the area where the heating module is located flows into the low-temperature refrigeration area again through an induced draught fan, in this reciprocating cycle, due to the continuouscirculated injection of the cold air flow, cooling and constant-temperature operation of component modules in the cabinet in the charging pile is realized. The method can realize the circulation of hot and cold air in the cabinet, and complete heat exchange with the external environment, the refrigeration effect is good, and the medium contact with the external environment is avoided, thereby realizing zero pollution in the cabinet.
Description
technical field [0001] The invention relates to the technical field of charging pile equipment, in particular to a method for circulating refrigeration in a charging pile. Background technique [0002] Traditional charging pile cabinets use fan pumping and exhaust cooling methods. Generally, industrial-grade fans are installed on both sides of the cabinet to exhaust the high temperature generated inside the cabinet to the outside of the cabinet, allowing the internal air to form convection to cool down. role. But it also exposes its existence to have the following disadvantages: [0003] (1) In order to prevent the dust and water of the air in and out, the ventilation and heat exhaust circulation port of the traditional fan uses multi-layer sponge as the filter plate, resulting in only a very small amount of air in and out, and over time, the filter sponge plate of the air inlet There may be a risk of being completely blocked by the external gray layer, which will greatly ...
