Description
Technical Field
The utility model relates to a passenger train air conditioner field specifically relates to a ventilation heat radiation structure of passenger train overhead air conditioner electrical system assembly.
Background
The electric system of the air conditioner of the pure electric overhead bus integrated in new energy in the current market is generally integrated in an independent structural cavity of the overhead air conditioner, and the air conditioner performs ventilation and heat dissipation with electric elements and the air of the external environment of the bus when in operation, but the following failure modes exist:
1. the air is ventilated and radiated with the external environment for a long time, excessive dust inevitably enters an electrical system, and faults such as short circuit, overheating and the like of an internal circuit of the electrical system can be caused;
2. when the external environment is in a high-humidity environment for a long time, the inside of the electric appliance is possibly reduced in insulation level due to overlarge humidity through ventilation and heat dissipation, and the safety risk of the electric appliance exists.
3. When the external environment is in an extremely high temperature environment, the electrical system cannot perform effective thermal efficiency heat dissipation with the external air, which may cause that the normal service life of some electrical components is reduced or even damaged due to overhigh temperature.
SUMMERY OF THE UTILITY MODEL
To the above situation, the utility model provides a ventilation cooling structure of passenger train overhead air conditioner electrical system assembly.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a ventilation cooling structure of passenger train overhead air conditioner electrical system assembly, includes the fixed bolster, the fixed bolster passes through bolt fastening in evaporating chamber return air inlet department, be equipped with dustproof construction on the fixed bolster, be equipped with electrical assembly power electrical components in the dustproof construction, dustproof construction is including setting up in the shield at fixed bolster top and setting up in fixed bolster dust guard all around, be equipped with ventilation structure on the fixed bolster, ventilation structure department is equipped with the ventilation cooling fin piece, ventilation structure is the vent that sets up on the fixed bolster of a plurality of bilateral symmetry.
Furthermore, the fixing support is made of aluminum alloy.
Furthermore, the dust guard and the fixed support can be detached and fixedly connected.
Further, the fixed support is matched with the evaporation chamber in shape and size.
Has the advantages that:
the ventilation and heat dissipation structure of the bus overhead air-conditioning electrical system assembly reduces the cavity space of the independent external electrical structure by moving the electrical system to the air return port of the evaporator, so that the product structure is more compact, and the product weight can be reduced; the electric appliance radiating fins are integrated at the position where the internal circulation air duct flows through, the electric appliance system is ventilated and radiated through the internal environment of the vehicle during operation, and the power electric element of the electric appliance assembly is completely isolated from the ventilation air duct, so that the temperature, the humidity and the cleanliness of the working environment of the electric appliance system assembly are greatly improved compared with the traditional structure.
