Automotive electric drive air conditioner

Abstract

The invention discloses an automotive electric drive air conditioner, and relates to the technical field of air conditioner manufacturing. The automotive electric drive air conditioner comprises a box shell. One end of the box shell is provided with an air inlet. The other end of the box shell is provided with an air chamber. The air chamber is provided with three air outlets which form an air flow passageway together with the air inlet. An evaporator, an air feeder and a heater are sequentially arranged in the air flow passageway from the air inlet. The included angle between the air feeding direction of the air inlet and the air feeding direction of the evaporator is 90 degrees. The direction of the inlet of the evaporator is the same as the direction of the inlet of the air feeder. The spatial included angle between the evaporator and the heater is 90 degrees. The heater is arranged in front of the outlet of the air feeder. A rotating air door is arranged in the air chamber. The automotive electric drive air conditioner can solve the problems that due to the facts that an existing automotive electric drive air conditioner is large in size, connecting pipelines and air ducts are too long and pipeline arrangement is complex, cold air loss and hot air loss are large when the air conditioner is used, and efficiency of the air conditioner is low.

Description

technical field [0001] The invention relates to the technical field of air conditioner manufacture, in particular to an air conditioner used for adjusting the temperature in the cab of an automobile. Background technique [0002] At present, the main parts of the air conditioner on the car, such as evaporator, blower and heater, etc., are generally arranged under the dashboard in the car, connected by pipelines, and the air duct is connected with the cab of the car. The blower is arranged on the air inlet side or the air outlet side of the evaporator and heater, and the heating box has a complex structure and a large volume. [0003] This kind of vehicle electric drive air conditioner has the following disadvantages: 1. The connecting pipes and air ducts of each air-conditioning component are too long, and the arrangement is complicated, and the loss of cold and hot air is relatively large in actual use; 2. It is connected with the engine, generator, oil pump, If the water ...
