Description
Technical Field
[0001] The utility model relates to the technical field of locomotive air conditioners, in particular to a high-temperature improved locomotive air conditioner with a spray system. Background Art
[0002] The locomotive is the power source of the entire train. It is equipped with a large number of high-power energy-consuming equipment inside, which will generate a lot of heat. At the same time, since the locomotive structure is made of metal iron, it has strong thermal conductivity. It is difficult for train drivers to work in the locomotive for a long time in the hot summer. Therefore, it is necessary to have a stable and reliable locomotive air-conditioning system to support it.
[0003] The existing devices have the following shortcomings when in use: when the temperature is too high in a high temperature environment, the air conditioner may have difficulty in heat dissipation when cooling, resulting in high-pressure protection of the air conditioner compressor. The air conditioner will not be able to cool and cannot meet the needs of the train driver, resulting in constant complaints from the driver and posing a hidden danger to locomotive safety. Utility Model Content

The condensed water sprayed from the nozzle forms water mist and is sprayed on the locomotive air conditioner to cool the locomotive air conditioner. At the same time, the fan installed on the spray plate blows air to dissipate heat for the locomotive air conditioner. The blowing and cooling of the fan increases the air circulation to evaporate the water mist and prevent the water mist from accumulating into water flow. At the same time, the process of liquid evaporation into gas is an endothermic process, which can absorb more heat from the locomotive air conditioner, improve the heat dissipation effect of the locomotive air conditioner, and effectively avoid the problem of high-pressure protection of the compressor of the air conditioner due to excessively high ambient temperature, which meets the normal use of the driver in the hot summer.
