- the cooling heat exchanger is characterized in that the cooling heat exchanger is tilted so that the lower end portion is positioned in front of the vehicle traveling direction with respect to the upper end portion in the vehicle vertical direction ( Claim 1).
- the blower unit and the air conditioning unit main body are arranged with an offset along the vehicle width direction. Further, the defrost blowing opening and the vent blowing opening are opened in the upper surface of the unit case. Further, the side surface portion of the unit case on the side of the firewall is erected substantially vertically in the vertical direction of the vehicle so that the air conditioning unit main body can be disposed close to the firewall. .
- the air mixed A is arranged on the windward side of the heat exchanger for heating and is arranged in a hot air door for adjusting the amount of air sent to the heat exchanger for heating and a cold air passage, and the heat exchanger for heating is A cold air door for adjusting the amount of air to be bypassed, and when the hot air door closes the windward side of the heating heat exchanger, the leeward ventilation surface of the cooling heat exchanger and the temperature A substantially triangular space is defined by the wind dough and the side surface of the unit case, and the top of the substantially triangular space and the cold air passage are continuous (claim 2). ).

- the hot air door 10A with the upper side closed and the side surface 11B on the side of the fire wall 4 can act as an air guide to smoothly send air to the cold air passage 25, so ventilation is possible even in the full cool mode. In addition to reducing resistance, it is possible to secure a large air volume and reduce noise in the full cool mode.
- the air from the blower unit portion 2 is taken in from the air intake port 7 positioned relatively below the unit case 11 and is relatively upper. Because it flows along the vertical direction of the vehicle toward the blowout openings 16, 17, 18, it is not necessary to define a useless air passage, and the width along the longitudinal direction of the vehicle is reduced. Can do. Furthermore, in this air flow, the cool air passage 25 and the defrost blowing opening 17 are in a substantially linear position in the vertical direction of the vehicle, so the flow of the cool air becomes smooth and the air resistance can be reduced.
- the blower unit portion 2 has the winding start end portion 23A of the scroll-shaped unit case 2A positioned on the lower end portion side with respect to the tilting direction of the cooling heat exchanger 8.
- the winding terminal end 23B of the unit case 2A is positioned on the upper end side with respect to the tilting direction of the cooling heat exchanger 8.
- the air intake 7 has a wide opening area at the rear side in the vehicle traveling direction and a narrow opening area at the front in the vehicle traveling direction. Accordingly, according to the relationship with the blower unit 2 having the above-described configuration, the winding start end 23A of the unit case 2A Since the opening area on the winding end 23B side of the unit case 2A, which has a large opening area on the side, becomes smaller, the mainstream part of the air on the winding start end 23A side of the unit case 2A is the vehicle in the air inlet 7 It can pass through a relatively large opening area on the rear side in the traveling direction with a relatively small pressure loss. Therefore, since the air volume from the blower unit 2 to the air conditioning unit body 3 can be increased, the performance of the air conditioning unit 1 can be improved.
