Description
Technical field
The utility model and a kind of air supply rate, be specifically related to the hermetically-sealed construction of a kind of fan heater air door axle and housing.
Background technology
Fan heater of vehicle air conditioner air door mainly plays guiding and the switching effect of air flow within air-conditioning systems, its sealing ensure that wind direction is in handoff procedure, can carry out accurately switching and leading, ensure that each air outlet enough air output and air-out effect accurately, the actual refrigerating capacity of air-conditioner air outlet or heating capacity demand to greatest extent, meets the demand of client to air-conditioning effect.
Be subject to the factors such as design tixed thinking and client ignore, we are at air door design phase in early stage, do not consider air leakage phenomena when air door and heater unit axially coordinate, think that this position is leaked out smaller, or it is inevitable (because there being the gap of axis and radial fit when axle of the air door and heater unit housing coordinate to leak out, otherwise air door cannot freely rotate), therefore often do not consider to leak out in this position at design phase, or know obviously that its existence is leaked out, but wait until that product mold out carries out day after tomorrow leakage detection afterwards and fills a vacancy.
Existing air-conditioning, adopt gap fiting mode between axis hole on its axle of the air door and air-conditioner housing, but gap value is wayward in Design and manufacture process, if tolerance clearance is less than normal, air door can be caused to rotate difficulty, tolerance clearance axle of the air door generation end float misalignment and the radial direction while rotation of allowing again bigger than normal is rocked, and causes Air Leakage.Therefore existing air door structure more difficult control air door end float misalignment, radial direction are rocked and Air Leakage.
