Abstract

The DC60 (22/08/44) Vehicle air conditioning unit incorporates a swivel frame cover. Blower fan with volute air duct and heat exchanger unit. The heat exchanger unit is attached to the swivel housing. and has an air intake port connected to the air outlet of swivel cover The wall adjusts the wind direction to be straight. Sort the air released from the air outlet. Straightening walls will be placed. in a position corresponding to the inward radial position of both the air outlet of the swivel cover and the air inlet of the heat exchanger unit Noise may be suppressed. and blowing performance in a wide range during operation where large pressure loss and low pressure loss operating may be added. By the wall straightening the air passages, noise in operating at high pressure loss is effectively suppressed. and may prevent degradation of blowing efficiency The vehicle air conditioning equipment includes a swivel frame cover. Blower fan with volute air duct and heat exchanger unit. The heat exchanger unit is attached to the swivel housing. and has an air intake port connected to the air outlet of swivel cover The wall adjusts the wind direction to be straight. Sort the air released from the air outlet. Straightening walls will be placed. in a position corresponding to the inward radial position of both the air outlet of the swivel cover and the air inlet of the heat exchanger unit Noise may be suppressed. and the efficiency of blowing in a wide range during operation where large pressure loss and low pressure loss operating may be added. By the wall straightening the air passages, noise in operating at high pressure loss is effectively suppressed. and may prevent degradation of blowing efficiency

Claims (2)
