And a restricting portion that abuts the fixing cover at the fixed position.

  Therefore, when the heat exchanger is inserted into the air conditioning case through the opening, the fixing cover is guided to the predetermined fixing position by the guide portion of the air conditioning case, and the fixing cover comes into contact with the regulating portion at the fixing position. It is positioned by doing. As a result, when inserting and assembling the heat exchanger from below into the air-conditioning case, the pipe can be easily guided to a predetermined fixed position via the fixing cover and securely fixed in a positioned state.

  In addition, by positioning the fixing cover by the regulating portion and fixing the fixing cover by the fixing member, the fixing cover positioned to the fixing position by the guide portion can be more firmly fixed by the fixing member.

  Furthermore, by using the heat exchanger as the indoor heat exchanger of the heat pump, the fixing cover is made of a heat-resistant material, so that the indoor heat exchange becomes higher than the piping of the heater core connected to the cooling water circuit of the internal combustion engine. Since the piping of the container can be held by the fixing cover, it is not necessary to form the air-conditioning case with a heat-resistant material, so that the manufacturing cost can be reduced.

  Furthermore, the guide portion is formed so as to open downward on the side surface of the air conditioning case, so that when the heat exchanger is inserted upward through the opening portion of the air conditioning case, the guide portion simultaneously moves upward. The cover can be easily inserted into the inside from below the opening of the insertion guide.

  Furthermore, since the restricting portion has the first restricting portion extending in the vehicle width direction and the second restricting portion extending to the front side of the vehicle, the restricting portion contacts the first restricting portion. It is possible to restrict the movement of the fixing cover in the vehicle longitudinal direction and to restrict the movement of the fixing cover in the vehicle width direction by contacting the second restricting portion.

It has a mix damper 100, a first switching damper 102 for switching the ventilation state of the vent ventilation port 26 and the defroster ventilation port 28, and a second switching damper 104 for regulating the ventilation state to the foot ventilation port 30.

  The vehicle air conditioner 10 according to the embodiment of the present invention is basically configured as described above. Next, a case where the indoor heat exchanger 18 is assembled to the air conditioning case 14 will be described. It is assumed that a fixing cover 70 is previously attached to the pipe connection portions 66 of the heat pipes 64a and 64b.

  First, the heat exchange portion 60 of the indoor heat exchanger 18 is inserted into the inside from the lower side of the air conditioning case 14 shown in FIG. 1 through the insertion port 32, thereby obliquely upward along the guide wall 34 (in the direction of arrow D in FIG. 1). ) And are stored. At the same time, the heat pipes 64a and 64b wrap around the lower side of the first split case 22 and the side wall 22a, and the fixing cover 70 attached to the pipe connection portion 66 moves obliquely upward along the side wall 22a and is fixed. Approaching the part 36.

  Then, by moving the indoor heat exchanger 18 further obliquely upward along the guide wall 34, the upper tank portion 62b approaches the holder 58 of the air-conditioning case 14 and the insertion portion 82 of the fixing cover 70 Becomes a position facing the insertion guide 38 of the fixing portion 36, and the main body portion 84 is inserted upward from the widened portion 44 of the insertion guide 38. At this time, since the insertion guide 38 has the widened portion 44 gradually widened in the insertion direction of the insertion portion 82 at the opened lower end portion, the insertion portion 82 can be easily inserted into the inside. It becomes possible.

  By moving the indoor heat exchanger 18 further upward, the upper tank portion 62b is held by the holder 58, the lower tank portion 62a is housed inside the insertion port 32, and the fixing cover 70 In the insertion portion 82, the main body portion 84 moves from the widened portion 44 of the insertion guide 38 to the inside of the linear portion 42, and the wide portion 86 is housed in the widened portion 44. As a result, the fixing cover 70 is inserted into the insertion guide 38 of the first split case 22 so that the insertion portion 82 having substantially the same shape is inserted into the insertion guide 38, so that the fixing cover 70 is relatively moved in the front-rear direction of the vehicle (the direction of arrows A and B). Is restricted (see FIG. 3B).

  4B, the arm portion 76 of the first cover member 72 contacts the first regulating portion 52 provided at the lower end of the insertion guide 38 on the vehicle rear side (in the direction of arrow B). The hook 78 abuts and engages with the second restricting portion 56 on the side wall 22a side of the first split case 22 (in the direction of arrow C2 in FIG. 4A). Thereby, the relative movement of the fixing cover 70 in the front-rear direction (the directions of arrows A and B) of the vehicle is regulated by the contact between the first cover member 72 and the first regulating portion 52, and the second regulating portion The movement in the width direction (the direction of arrow C) is also restricted by the contact with 56.

  At this time, in the fixing cover 70, the holes (not shown) of the first cover member 72 face the first and third screw holes 48 and 54, and the holes of the second cover member 74 correspond to the second screw holes 50. It is arranged to face.

  Finally, the fixing screws 46 are inserted into the holes of the first and second cover members 72 and 74, and screwed into the first to third screw holes 48, 50 and 54, respectively, to thereby form the first and second holes. The fixing cover 70 composed of the two cover members 72 and 74 is fixed to the fixing part 36, and accordingly, the heat pipes 64 a and 64 b including the pipe connecting part 66 are fixed to the fixing part 36 of the first split case 22. Securely fixed. Thereby, the work of assembling the indoor heat exchanger 18 to the air conditioning case 14 is completed.

  Next, the operation of the vehicle air conditioner 10 in which the indoor heat exchanger 18 is assembled to the air conditioning case 14 as described above will be described with reference to FIG.

  First, when performing a cooling operation for supplying cool air to the vehicle interior, the first air mix damper 96 is fully closed and the second air mix damper 100 is fully opened based on an operation of a passenger (not shown). , The downstream side of the evaporator 16 and the bypass passage 98 communicate with each other. Further, the first switching damper 102 is rotated toward the defroster air outlet 28 side, and the vent air outlet 26 and the bypass passage 98 are communicated. As a result, the air supplied from the blower (not shown) to the air conditioning case 14 and cooled by the evaporator 16 is supplied to the vent ventilation opening 26 opened through the bypass passage 98 and is blown to the vicinity of the occupant's face in the vehicle interior. .

  Next, when switching from the cooling operation to the heating operation described above, the first air mix damper 96 is turned from the fully closed state and the second air mix damper 100 is turned based on the operation of a passenger (not shown). By setting the fully closed state, the communication between the downstream side of the evaporator 16 and the bypass passage 98 is cut off. Thereby, the air cooled by the evaporator 16 is supplied to the indoor heat exchanger 18 on the downstream side, and the hot air heated by passing through the indoor heat exchanger 18 is, for example, supplied to the second switching damper 104. The air is blown to the vicinity of the foot of the occupant in the passenger compartment through the foot air vent 30 opened under the rotation action.

  As described above, in the present embodiment, in the air conditioning case 14 configuring the vehicle air conditioner 10, the indoor heat exchanger 18 is inserted upward into the air conditioning case 14 through the insertion opening 32 opened downward. At this time, the fixing cover 70 that covers the pipe connection part 66 that bundles the ends of the heat pipes 64a and 64b has the insertion part 82 provided on the inner side in the width direction (the direction of the arrow C2). By being inserted into the insertion guide 38 provided in the part 36), it is easily guided to a predetermined fixed position. Further, the arm portion 76 of the fixing cover 70 abuts on the first regulating portion 52 of the regulating rib 40 provided on the air-conditioning case 14, and the hook 78 provided at the end of the arm portion 76 engages with the second regulating portion 56. The movement of the fixing cover 70 in the vehicle front-rear direction (arrows A and B directions) and the width direction (arrow C direction) of the fixing cover 70 is regulated.

  As a result, when the indoor heat exchanger 18 is inserted into the air conditioning case 14 from below and assembled, the pipe connection portions 66 provided at the ends of the heat pipes 64a and 64b can be easily moved to the fixing position of the air conditioning case 14. And it can guide and position reliably.

  After the indoor heat exchanger 18 is inserted into the air-conditioning case 14 through the insertion opening 32, the fixing rib 40 is fixed in the vehicle front-rear direction (arrow A and B directions) and the vehicle width direction (arrow C direction). By fixing the cover 70 to the fixing portion 36 with the fixing screw 46, it is possible to more firmly fix the ends (the pipe connection portions 66) of the heat pipes 64 a and 64 b to the air conditioning case 14. The restricting ribs 40 function particularly effectively when the indoor heat exchanger 18 is inserted upward toward the front of the vehicle as in the present embodiment.

  Further, the heat pipes 64a and 64b in the indoor heat exchanger 18 of the heat pump used as a heater have a higher temperature than pipes of a heater core connected to a cooling water circuit of the internal combustion engine, and therefore generally have higher heat resistance. Although it is necessary to form the air-conditioning case 14 with a member having high heat resistance, the air-conditioning case 14 according to the above-described embodiment adopts the fixing cover 70 made of a heat-resistant material, thereby making the air-conditioning case 14 heat-resistant. Since it is not necessary to form from a material and can be formed with an inexpensive material, it is possible to reduce the manufacturing cost.

  The vehicle air conditioner according to the present invention is not limited to the above-described embodiment, but may adopt various configurations without departing from the gist of the present invention.
