Technical Field

[0001] The invention relates to the technical field of condensing fan equipment, in particular to a condensing fan mesh cover with snow prevention and snow removal functions. Background Art

[0002] Among the current air-conditioning components of new energy electric buses, the condensing fan is an important component for the normal operation of the air-conditioning. Its function is to achieve the purpose of ventilation and heat exchange through forced ventilation. When the condensing fan is running, the wind direction of the air-conditioning condensing fan is generally gathered to the center of the condensing fan through the mesh cover on the condensing fan, thereby forming a high-pressure airflow and pushing it out, thereby ensuring the normal heat exchange of the condenser.

[0003] When an electric bus is in a snowy environment, once the mesh cover on the condensing fan is covered with snow, the airflow in the condensing fan will be difficult to discharge, making it impossible for the condensing fan to effectively exchange heat and the air conditioning system of the bus to operate normally. After the condensing fan outdoor unit is covered with snow, it needs to be cleaned by personnel before the air conditioning can be turned on normally. Manual cleaning is very inconvenient and the cleaning process is relatively cumbersome. Summary of the invention

[0006] The beneficial effect of the present invention is that when the mesh cover of the condensing fan is covered with snow, it is heated by the arranged heating part, so that the temperature of the mesh cover base and the mesh cover top seat will rise rapidly, so that the snow can melt rapidly. After the snow is eliminated, the air conditioner condensing fan can be turned on normally, ensuring the normal operation of the air conditioner heating function.

[0007] Based on the above technical solution, the present invention can also be improved as follows.
