Description

Automatic change electric cabinet of cooling

Technical Field

The utility model relates to the technical field of power conversion cabinets, in particular to an automatic cooling power conversion cabinet.

Background

The battery changing cabinet is a cabinet specially used for changing a battery pack to be charged of the electric vehicle into a charged battery pack, a user can directly put the battery pack to be charged into the battery changing cabinet and directly change the battery pack to be charged, normal riding can be met, the trouble of charging can be omitted for the user, the charging mode of the existing electric vehicle is broken, and the time of the user is saved. However, in the charging process of the battery changing cabinet, the internal heat accumulation phenomenon is serious, and the cooling system of the battery changing cabinet generally uses an exhaust fan at present, so that the purpose of cooling the battery pack is achieved by circulating air in the cabinet body. Because the baffle is arranged between the battery bins of the battery replacement cabinet, the air fluidity between the bins is poor, and the exhaust fan can not rapidly exhaust the air in each bin. And the temperature of the air at the periphery of the battery cabinet is also high, and after the exhaust fan is used for exhausting hot air in the bin, the external high-temperature air can also enter the bin under the action of air pressure, so that the cooling performance of the exhaust fan is greatly reduced. Most of the existing batteries are lead-acid batteries and lithium batteries, and the use place of the battery changing cabinet is generally located in a place without cold air outdoors. When the battery is charged in summer, the temperature of the battery is high, and the temperature is high, so that the battery is extremely easy to generate thermal runaway.

Although some existing battery-changing cabinet manufacturers improve the structure with active heat dissipation function outside the traditional exhaust fan, some problems still exist in practical application, such as the utility model patent with application publication number of CN 110611139A, namely, a continuous cooling system for the battery-changing cabinet, the system can realize rapid cooling of the battery compartment by spraying coolant into the battery compartment, although the refrigeration performance is far from that of the traditional exhaust fan, the coolant is a substance which cannot be continuously regenerated and used, and needs to be replenished after a period of use, and the high-pressure medicament bottle also has explosion safety risk inside the cabinet body with higher temperature. In addition, some battery changing cabinets with active heat dissipation structures, such as the battery changing cabinet with active cooling structure disclosed in patent number CN 217692264U, are realized by semiconductor refrigerating sheets, but each compartment only carries out air flow exchange through small doors on the inner wall, the air flow channels are of corner structures rather than straight line through, the circulation of cold air is not rapid enough, and the compartment walls of the compartment and the cabinet walls of the battery changing cabinet form two heat insulation barriers, so that the transfer efficiency of the battery charging heat in the compartment is reduced. In addition, the heat end of the semiconductor refrigerating sheet is also required to be provided with a heat dissipation exhaust fan, and the heat dissipation of the heat end of the semiconductor refrigerating sheet is poor under the long-time working condition, so that the refrigerating effect of the semiconductor refrigerating sheet is reduced.
